Operational Planning & Real-Time Reliability

Foreword

Foreword

This professional reference is one of a series Energy Compliance, Inc. publishes for registered entities and the people who run their compliance programs.

I’ve spent more than thirty years on every side of the bulk electric system. I’ve operated control centers as a Reliability Coordinator, Transmission Operator, and Power System Operator. I’ve audited grid facilities and signed off on findings as a senior compliance auditor. I’ve worked enforcement matters from inside the regulator’s process. For the last several years I’ve advised registered entities directly through the firm I founded.

The entities that do reliability well share a common habit. They take the standards seriously without confusing them with reliability itself. They know that a NERC Reliability Standard is a floor, not a ceiling. They know that compliance is something an auditor evaluates, but reliability is something a system either delivers or doesn’t. They prepare for audits by building programs that survive real questions, not binders that look thick.

That’s the perspective these references try to share. Each one focuses on a single topic. A standard family, an operational function, a regulatory framework, or an emerging industry challenge. Each one walks through how the topic actually works.

These references are written for the compliance manager who wants to understand the system, not just memorize requirements. For the legal counsel who has to brief a board honestly. For the senior operator who’s been told that compliance and reliability are the same thing and suspects they aren’t. And for the new compliance hire who got handed a binder and told good luck.

These references aren’t marketing material disguised as content. They’re the result of three decades of doing this work and watching it succeed and fail. I’ve written them in the same voice I use in a control room or in front of a Regional Entity audit team. Direct, evidence-grounded, honest about what the standards do and do not require.

Energy Compliance exists because most of the consulting offered to registered entities today is structured for billable hours rather than for outcomes. Every engagement is led by one senior practitioner. We don’t bring five people to a meeting that needs one. We automate the work that should be automated. We apply senior judgment to the work that requires it. If that approach matches what you’re looking for in a compliance partner, the back of this reference has our contact information.

If not, the reference still belongs to you. Take what’s useful. Apply it well. And remember the only test that ultimately matters: when the system needs to perform, does it?

EC-WP-304 Operational Planning and Real-Time Reliability

Chapter 1

The Reliability Framework Linking Planning and Real-Time Operations

Real-time reliability is largely dependent upon having adequate system models, boundaries and system behavior descriptions to ensure system conditions are known and identified at all times. This information is typically derived from planning activities and is used by the operator to “anticipate” the expected performance of the system and to prepare for expected or unexpected system events. In the event that the planning information is deemed to be inadequate (out of date, missing or incorrectly applied), the

real-time actions of the operator, regardless of the extent to which they exercise their available authority and discretion, may be rendered ineffective.

The article also addresses the role of reliability oversight in observing interactions between planning and operations. Oversight does not control operations or dictate planning methods. Rather, it observes if interfaces between planning and operations support reliable operations, that information is being properly used in real time and identifies emerging system wide issues and gaps as the system evolves.

This publication is for: - planners - operators - reliability coordinators - compliance personnel - other interested parties wishing to obtain knowledge of the interface between planning and real-time operation activities in support of reliability through a reliabilitybased perspective. The publication takes a reliability-based perspective to show how reliability is maintained across time horizons and, thereby, does not address operational or planning activities that must be undertaken to ensure that reliability goals and requirements are met.

Operational planning and real-time operations are distinct activities within the Bulk Electric System, but they are highly interdependent from a reliability perspective. Planning activities set expectations for system performance under defined scenarios, and real-time operations manage system performance as those scenarios actually occur or change. Reliability is preserved through operational coordination by synchronizing these activities through a framework of assumptions, information flows, and operational boundaries.

In the NERC reliability framework, planning and operations are viewed as two interdependent horizons: Planning Horizons (Standards 1 and 2) define the criteria that allow an hRP to ascertain the reliability of the system in the forward looking planning horizon (i.e., it establishes whether the future system has sufficient reserve to meet future load and handle expected outages); whereas Operations is viewed as a present and near future horizon that is tied to the planning horizon through operational planning that reflects the operational significance of the planning horizon assessments in a manner that does not dictate operational actions in real-time.

Operational planning uses Planning Study results, system model data and expected operating conditions to develop operating limits, expected contingencies and operational awareness tools. This enables operators to understand the expected behaviour of the system and the likely risk events that may arise. From a reliability perspective, operational planning is not about predicting the actual outcome of every scenario as and when it occurs, but rather about minimizing the level of uncertainty and providing a common framework to support everyday operational decisions made both during normal and abnormal operating conditions.

Real time operations are only effective if planning derived information is reliable. A major part of the Operating Constraint is based on information that has been derived from previous planning exercises.

Successful real time operation requires all planning assumptions to be valid to the conditions in the system at the time, for example, ratings derived from previous studies are valid and limits derived from planning studies are adequate to handle anticipated real time faults, otherwise real time operations whatever quality of operation is carried out will not be reliable to the extent determined by the failure of assumptions to meet real time conditions.

Reliability R v1.1 introduces the operational planning reliability framework, which accounts for the differing time horizons and conditions under which planning and operations activities occur. While planning activities involve a set of assumed conditions (scenarios) derived from forecasts of system operating conditions, operations occur based on real-time system conditions that can change quickly. Operational planning links planning to operations in a way that presents planning information in an operational context and that accounts for the uncertainty inherent in operational planning, while maintaining adherence to reliability standards.

Coordination between planning and operations is important, but potentially more complex in an interconnected system environment where actions in one area can cause wide-area effects. Reliability Coordinators, Transmission Operators, and other entities need to have an understanding of system limits and operating characteristics that is derived from planning work. Operational planning helps to coordinate the views of regional and local systems within a reliability framework.

These five high level oversight questions focus on the outcome of the interface between planning and real time operation. Reliability oversight focuses on whether the planned information is translated into a suitable operational environment and whether insights gathered from operations are reflected in reliability assessments. This dynamic interaction is important to ensure the planning environment adjusts to changing grid conditions, composition of resources, and operational practices.

The subject of this chapter is the relationship between planning, operational planning and real-time operations in a reliability context, and it has explained how these relationships support reliable outcomes and hence identifies potential points of divergence or misalignment and their reliability implications.

End-of-Chapter Summary

Planning and Real-Time Operations are two interdependent reliability functions that are tightly coupled through operational planning. Reliability planning identifies expected behaviors in the power system, while reliability real-time operations (RTO) corrects actual power system performance as it varies from the expected. Operational planning bridges the gap between the “what if” of reliability planning and the “as is” of power system operation, thereby reducing degree of uncertainty in operational decisions and increasing operational confidence in the planning assessments.

Maintenance of reliable operations is directly related to maintaining alignment of operational functions and effective use of operational experience feedback. Having established the foundation that defines the relationship between planning and operations and their role in supporting reliable operation of the Bulk Electric System (BES), the chapter then delves further into the interfaces and mitigation of related risks.

FROM THE FIELD

Day-Ahead planning and real-time operations are two different jobs with two different mindsets. The handoff is where reliability either holds or breaks.

Planning is what you do before. Operations is what you do during. The framework expects coherent transition between them, not parallel exercises.

Programs that staff planning and operations as separate domains miss the transition. The transition is the function the standards actually audit.

Chapter 2

Operational Planning as the Bridge Between Planning Horizons and Real- Time Conditions

Operational planning is a special class of reliability service within the reliability framework. Operational planning bridges the period between planning assessments of future system reliability and performance capacity, under forecasted conditions for the future, and real-time system operation. The planning assessments cover long-term future system reliability and performance capacity under forecasted conditions, while real-time system operation deals with present system performance. Operational planning ensures that the intentions of the planning assessments are translated into near-term reliability needs and conditions, thereby ensuring successful bridging between the two time frames. Operations planning usually deals with time frames from a day or so up to a season. In this horizon the planning environment is more certain than in the longer term strategic horizon, but still highly uncertain. Load forecasts and resource availability are more accurate and the planned configuration of the system is known. From a reliability viewpoint operational planning serves to reduce the amount of possible system states the operations personnel have to deal with. Operational planning has a number of reliability functions including: 1. Preparation of operating limits based on analyses carried out to determine the system’s ability to operate safely and reliably under both normal and emergency conditions. Operating limits are based on planning analyses that are performed to determine the ability of the transmission system to operate normally and to recover from disturbances in accordance with established reliability criteria. Operational planning does not establish reliability criteria - it is a function of taking the results of planning analyses and ensuring that the operational actions are suitable for the expected operating conditions in the near term. Reliability oversight determines whether the operational planning has successfully performed this function. An added benefit of operational planning is the enhancement of contingency awareness. Planning studies are developed with identification of credible contingency scenarios and system sensitivities in mind. With operational planning, this knowledge is tailored to expected system configurations and operating conditions for the planned period. The resulting knowledge of most-relevant risks is therefore not overloaded with information about contingencies that are unlikely to occur given the system conditions of the time. Operational planning and real-time operations interact in a cycle of approximation and correction. Once operational planning information is

incorporated into real-time operational decisions, the actions that occur reflect not only the plans, but the actual conditions experienced during real-time operations that may have not been captured in the planning. These experiences, in turn, contribute to reliability as planning assumptions are updated or modified for subsequent planning periods. This misalignment at the transmission and distribution interfaces is one of the biggest reliability challenges. When operational procedures are developed under outdated assumptions, missing system and load component models and misinformation about resource capabilities, the information that is available to operational personnel does not match realtime system behavior. Reliability oversight focuses on the impact of potential misalignments based on operational outcomes and observed practices as opposed to a prescriptive review of operational procedures and planning practices. Reliability Coordination and Operations Operational planning serves to coordinate operational activities among the various functions within the power system. Reliability Coordinators, Transmission Operators and Balancing Authorities are all using information derived from the operational planning processes to provide a common view of the operational state of the power system and to facilitate operating in a manner that is consistent with the established system parameters. Inadequate coordination in operational planning leads to operational misconceptions, which in turn cause potential operating problems during high voltage events to be untreated, due to uncoordinated actions by different groups. From a reliability perspective, operational planning is used to manage the uncertainty of the system state rather than to eliminate it. The structured planning context in which near term operations are considered, is a reliability resource that can be drawn upon, even when actual system conditions differ from planned conditions. Reliability oversight is used to determine that this operational planning function is effective in supporting real time reliability without constraining the method of how operational planning is conducted. This chapter examined the role of operational planning as a connective layer between the planning horizons and real-time conditions. By elucidating the nature of this role and its boundaries it laid a foundation for understanding how reliability risk occurs when planning and operational conditions drift apart.

End-of-Chapter Summary

Operational planning is the activities carried out to provide a bridge between planning assessments and system operation, whereby planned assumptions are translated into short term reliability conditions, improved forecasts, operating limits and contingency knowledge to ultimately reduce uncertainty for the operational personnel.

Reliability Risk at the Operations Interface The level of reliability that can be achieved in an operating system is directly dependent on the reliability of the information supplied to operations in a timely and relevant manner, i.e., consistency, timeliness, and adaptability. Misalignment at this interface can

introduce significant reliability risk and hence operational planning must be recognized as an important control for reliability.

FROM THE FIELD

Operational planning bridges weeks-out studies and minute-by-minute operations. It's a service the framework relies on but doesn't always make visible.

The operational planner who hasn't sat the operating desk doesn't understand what the operator will face. The desk experience changes the planning judgment.

Planning that doesn't consider operating constraints produces studies that operations can't use. The studies become reference documents, not operational tools.

Chapter 3

Translation of Planning Assumptions into Operating Limits and Tools

Real time reliability is heavily dependent on how planning assumptions are translated into operational limits and situational awareness tools. The planning studies that are performed are based on certain assumptions about the expected state of the grid, and the resulting planned states need to be translated into some form of operational construct(s) that the operations team can use in real time. From a reliability framework perspective, this translation of planned states into operational constructs is a very vulnerable interface, where the potential for misalignment and resulting exposure to systemic risk exists. Relates to planning assumptions: Planning assumptions are highly abstract and deal with postulated system states, load scenarios, resource capacity and contingencies. These assumptions are valid for the analysis environment but not for the operational environment. Thus the main purpose of operational planning functions is to translate these assumptions into: Operating limits that reflect the desired actions at the time of a disturbance Monitored variables to ensure adherence to the assumed planning conditions Analytical aids such as prediction of system performance and assessment of emergencies. Operational limits are one of the clearest expressions of planning assumptions in realtime operations. In addition to resource adequacy planning and operational studies addressing post contingencies or stressed operations, reliability oversight would examine whether operational limits are associated with corresponding planning assessments and analyses, and whether these operational limits are maintained current as the system configuration and parameters change. Again, it is not the numerical value of the limits that is the focus of the oversight but the connection between planning and their operational application. - Situational awareness tools are another example of planning assumptions. Contingency analysis tools, system models, and monitoring constructs are based on the system topology and resource behavior assumptions made during planning. If these assumptions hold in the actual system, then operator situational awareness will be enhanced. However, if the assumptions no longer hold, then the operator will be dealing with increasing

amounts of uncertainty and the task of taking adequate control actions will become correspondingly more difficult. A repeating reliability risk comes from assumptions being present in operating tools for longer than they are valid or applicable. Shifts in the energy mix, network configuration, or operating

procedures can significantly alter system behaviors that are reflected in the operating procedures and dynamic models used in planning. The reliability oversight does not have anything to do with whether changes were made to operating procedures, dynamic models or planning assumptions; it deals with whether mechanisms were in place to handle assumption drift in relation to the particular operating procedures, dynamic models or planning assumptions in place at that time. Translation involves prioritisation as well. Although planning studies may cover a range of sensitivities and contingencies, operational tools have to focus on those that are relevant in the current operating context. In operational planning, the components, parameters and scenarios that need to be tracked in greater detail are determined based on the current operating context and needs. Reliability oversight will then ensure that operational priorities are in line with current system risk rather than historical planning priorities. Coordination among entities is another reliability concern in the translation of planning assumptions. Consistency of operating limits and operational tools among the various entities that use them, such as Transmission Operators, Balancing Authorities, and Reliability Coordinators, is important for coordinated wide area system response. Discrepancies or differences in assumptions and models among entities can lead to different views of system conditions during disturbance, which affects reliability. From a reliability perspective, the conversion of planned conditions to operational criteria and operational tools is a dynamic process. It is not a static process and conditions in a power system can change dynamically. This reliability activity monitors the impact of any difficulties that arise from the interface between planned conditions and system performance with the realization that any major system disturbance can highlight any unreliability in the power system which may be at variance with the planned conditions. Reliability Control, Operation Planning Chapter 10 discussed the translation of planning assumptions into operational constraints and operational tools for ensuring reliability in real time. Because of its focus on alignment, traceability and adaptability, this interface is perhaps the most important reliability control point.

End-of-Chapter Summary

Plans assumptions affect the real-time reliability of a traffic management system through their translation into operational limits and situational awareness tools. This translation step transforms planning evaluation judgments into operational context.

Reliability risk occurs when the limits and tools for operating within those limits are no longer relevant to the current state of the system or its planned condition. This chapter highlights the importance of maintaining traceability and coordination and making adjustments as required in order to ensure that the assumptions in the planning process are still applicable in the applications used for operating the system.

Chapter 4

Information Flow, Coordination, and Shared Situational Awareness

Real-time reliability of the Bulk Electric System can only be assured if the assumptions used for planning and operational planning are correct and within agreed upon limits and if there is good communication and coordination of information between operational entities. The reliability context is created by the planning and operational planning processes, but it must be disseminated, understood and agreed to in order to facilitate shared situational awareness. Failure to communicate, which is a fundamental aspect of RRS, can compromise even the most reliable planning and operational practices from a reliability framework perspective. Realtime reliability information is derived from a variety of activities including, but not limited to, planning and operational planning studies. This information typically includes information related to planned system states and boundaries, operating limits, expected constraints, and sensitivities. Operational planning processes and integrates this information to support operator, reliability coordinator, and other real-time reliability stakeholder activities throughout the operating horizon. Achieving shared situational awareness (SA) means that all entities share the same interpretation of the same information. This implies that Transmission Operators (TOs), Balancing Authorities (BAs), and Reliability Coordinators (RCs) each operate at different scopes and time horizons but are tightly interdependent in their actions. Common understanding of the Bulk Power System (BPS) SA from generation to consumption and across the various domains including system planning and operational planning is critical to achieving Reliability. This scenario identifies a coordination challenge arising from incomplete, stale or missing information that may be scattered among various entities. It addresses the ambiguity that can arise from the use of different models, assumptions or data sources leading to different perceptions of the state of a system. Reliability in this scenario is more concerned with the means by which ambiguities are addressed and resolved, rather than with the communication media used to address them. The timing of information sharing is also an area to consider for reliability. Without timely and dynamic planning-derived information, operational personnel may find the data insufficient for their near-term needs. This could result in the need for more frequent or other forms of information sharing. Operational planning is essential to enabling timely and relevant information to be provided to operational personnel in advance of execution, thus enabling on-going updates to the information shared. Reliability assessment of information sharing covers whether the necessary information is received in a timely manner to support operational planning and execution decisions. This source of reliability risk is the risk of information overload. When preparing the system for entry into

operation and in the process of developing detailed operational planning activities may produce vast amounts of analysis. However it is not all relevant to the operational conditions. In operational planning it is important to present only the essential information to ensure that the operators have right level and amount of knowledge for their work at any time. Reliability of oversight is about whether information is presented in a way that secures focus and concentration on the essentials. One of the key elements of information flow in relation to Reliability is the backward link from real-time operations to the planning and operational planning functions. Such experience is very valuable in terms of highlighting where discrepancies occur between system design assumptions and actual performance, so as to correct assumptions and thus improve the basis for future planning studies. A reliable system requires that such links exist and are effective. Section 5 Reliability through Information Flow and Co-ordination This chapter gives particular emphasis to the information flow and co-ordination required to connect the strategic planning phase with the tactical operations phase. It focuses upon common situational awareness and communication, to establish that reliability is more than just about the accuracy of preventive maintenance; that it also requires continuity in complex systems across organisational and spatial boundaries.

End-of-Chapter Summary

Timely and relevant information exchange is critical to the sustainment of shared situational awareness across levels of war from planning through operational planning and real time tactical operations. Relevant planned information must be transmitted, understood, and judged as critical or pertinent by all affected elements, functions, and systems to enable military success.

Reliability risk is a classic example of reliability risk due to outdated, disjointed or too much information. This chapter has emphasized the importance of communication within ODS, between OTS and Operations and the use of feedback loops to ensure alignment between planned operational actions and actual real-time operational conditions and activities.

FROM THE FIELD

Planning data flows to operations. Operating data flows back to planning. If the loop is broken, both sides operate on outdated information.

Shared situational awareness across planning and operations isn't a poster on the wall. It's a procedural commitment, evidenced by communication discipline.

Programs that have weekly planning meetings without operations participation don't have shared situational awareness. They have parallel meetings.

Chapter 5

Managing Uncertainty Across Planning and Real-Time Horizons

The operation of the Bulk Electric System (BES) inherently involves a degree of uncertainty. Planning activities rely on forecasts and modeled scenarios, while real time operations happen in a best effort to reflect the actual conditions of the BES, which may differ from the planning scenarios. Reliability considerations include recognizing that uncertainty is unavoidable but manageable through defined interfaces between planning, operational planning and real time operations activities. Reliability through the management of uncertainty is an important consideration. Planning uncertainty is caused by assumptions concerning future load, generation availability, system configuration and operation. While assumptions are required for any analysis, they can significantly affect the accuracy of the resulting planning studies. The Reliability Oversight considers that no planning study can provide perfect insight into real time system performance, but the Planning Uncertainty process is used to assess the extent to which planning and operational planning activities address and deal with this uncertainty. Operational planning reduces uncertainty by progressively diminishing the ambiguity of initial assumptions as the planning horizon draws nearer. The accuracy of forecasts, the precision of system operating parameters and the reliability of underlying resource data will all improve. From a reliability perspective, the uncertainty facing the operator during real time management of the system is reduced by narrowing the domain of possible states that the system might be in, as opposed to reducing the inherent variability of these states. Inherent to real time operations is the residual uncertainty that cannot be fully resolved through the planning process. Real time operations deal with unexpected outages, weather events, or any other rapid changes to system conditions which make it impossible to have complete information for operational decisions. However, reliability is improved where the original planning and operational planning work has prepared the operator for possible contingencies and provided the operational degrees of freedom needed to manage credible contingency events and variability. The main source of uncertainty in real-time operations is discrepancies between assumptions built into plans and real world conditions. When unexpected phenomena are encountered in the system, real-time operations become very dynamic and time sensitive. Reliability oversight serves to establish whether these discrepancies are one-off events or manifestations of more widespread lack of planning and operational planning alignment. Reliability is about being prepared to unexpected events. Reliability is all about dealing with the unexpected, using the concept of margins, of having reserves, and being able to adjust. Planning and operational planning are elements that contribute to ensure reliability. They help identifying critical

points where potential unexpected events can create significant stress, and therefore allow operators to better prepare to counter potential unexpected changes resulting from uncertainties. Feedback mechanisms are used to deal with uncertainty as it arises over time. Operations experience are used to modify forecast assumptions and to fine tune the operational plan. Enhancing the level of reliability is a matter of transitioning uncertainty in operations into understanding (learning) rather than ongoing surprise. The previous chapter of this book examined how different types of uncertainty are managed across time scales in a reliability context. Here we introduce the reliability framework with the underlying assumption that uncertainty is always present except during extraordinary periods, and explore in more detail how reliability planning and operations can be made robust to these effects across planning and real-time horizon.

End-of-Chapter Summary

Uncertainty is present in both the planning and real time operation stages, due to assumptions included in the short term and medium term forecasts as well as due to changes that occur in the system conditions. Reliability is not built to eliminate this uncertainty, but by making this uncertainty manageable by defining proper interfaces between planning, operational planning and real time operations.

Operational planning reduces uncertainty as conditions become clearer and real-time operations manage remaining sources of uncertainty. This chapter links together the themes of alignment, resilience and feedback to consider their relationship to uncertainty within a reliability context.

FROM THE FIELD

Day-Ahead, hour-ahead, real-time. Three horizons, three different jobs. Each requires different tools, different staffing, and different decision authorities.

Programs that try to handle all three with the same staff and process underperform on all three.

The standards calibrate expectations to the time horizon. A delay that's tolerable in Day-Ahead is unacceptable in real-time.

Chapter 6

Operational Experience as Feedback to Planning Assumptions

All utility operating experiences are a rich source of actual BES performance information. Reliability planning and operational planning practices typically rely on model assumptions and forecasts. However, operational experience is a valuable check on the validity of the assumptions and forecasts used for these planning activities. Through the reliability operating experience feedback process, utilities may improve the correspondence between planning objectives and operating practices. Some operating conditions are not readily derived from typical planning studies. The dynamic performance of resources, or the unknown interactions and dynamic system behavior encountered, can differ from what is envisioned in static studies. From a reliability viewpoint these differences are not caused by inadequate planning but simply a consequence of limited foresight, requiring further study and/or more understanding of the particular system and operating conditions encountered. Reliability oversight concerns the level of visibility and accountability associated with ensuring that operational experience is being appropriately factored into management of the generation and transmission planning and operating processes. It does not refer to a reactive or an event triggered redesign of planning procedures. Rather it means that there is a constructive process of learning from experience where any deviations in system behavior from previous studies are captured and used to support updating of reliability assessments and promoting ongoing reliability awareness. One of the key sources of feedback to reliability planning is the incidence of disturbances, near-miss events, and other unusual operating conditions. These conditions expose system sensitivity and potential trouble spots that may not be revealed during normal system operation. Reliability oversight determines whether operational feedback from unusual system performance is properly analyzed and communicated back to the planning process where operating assumptions and design and operational limits are defined. This feedback loop contributes also to the calibration of the modeling expectations. As already mentioned, the planning models represent a simplified picture of the system behavior, and the operational experience can then be used as a validation benchmark. In the context of reliability oversight the focus is on the level of abstraction at which this calibration takes place, and not on the details of the adjustments that have to be made. Giving timely feedback is a reliability concern. Operational insights provided at some future time may no longer be pertinent to the current situation because the environment is dynamic and continues to change. Operational planning bridges this gap, capturing short-term operational knowledge and making it available within the planning context for the next operational cycle. Operations feedback

aids in developing a shared view among Functional teams. planners, operators and reliability coordinators will have a consistent view of how operations validate the assumptions in planning, thereby enhancing reliability and reducing opportunities for misunderstandings to occur. This chapter examined the role of operational experience as a feedback signal in reliability theory. This can be achieved by treating real time performance as input to planning rather than the exception.

End-of-Chapter Summary

Operational experience provides data that can be used to validate assumptions that were made during the planning stages of a system, as well as to determine where further information is needed. Deviations between planning assumptions and system performance provide insight for the need for model refinements as well as for general understanding of system performance.

Reliability is maintained through the provision of operational information on an ongoing basis in the operations centre. This information must be captured, interpreted and disseminated and must be integrated into operational planning processes and activities. The Chapter highlights through the use of feedback loops, the importance of agile reliability governance frameworks and their resilience.

FROM THE FIELD

Planning identifies the risks that could materialize in operations. Risk identification quality determines operating preparedness.

A planning study that didn't consider the contingency that materialized in operations is a study that missed something. The miss has to be examined; the lesson has to be codified.

Operating events that weren't planned for become the basis for the next planning cycle. The cycle works only if the lesson reaches planning.

Chapter 7

Reliability Risk Arising from Planning and Operations Misalignment

The mismatch between planning assumptions and real-time operating conditions is a persistent reliability risk to the Bulk Electric System. Planning and operational planning provide a basis for expected system performance. Real-time operations deal with actual system conditions that may be quite different from those assumed in planning and operational planning. When these differences become material, reliability risk to the BES can arise, even in the absence of operational error or planning deficiency, when viewed in isolation. Misalignments can occur in various forms within Planning and Operations activities. The Planning Assessment could be based on system or resource conditions derived from a system configuration or resource behavior snapshot that does not represent the current state of the grid. Operational tools or staff may still reference constraints, transfer limits or transfer risk sensitivities derived from the previous planning assessment. Or, operational events are developing so quickly that it becomes impractical to observe a full planning cycle between operations and planning activities. Reliability oversight monitors events for this type of misalignment based on what happens over time rather than whether a particular action was individually appropriate. - One of the reliability issues associated with misalignment is “Erosion of Predictability” (EOP). Reliability and operational effectiveness of grid operations benefits from a relatively high degree of situational awareness that operators possess as a result of their understanding of their system and operational expectations based on solid planning. Their expectations of system behavior to normal and unusual operating situations and disturbances or contingency events are a direct result of their planning activities. If the actual behavior of their system is sometimes “materially” different from the expected behavior, the situational awareness may be “eroded,” significantly increasing the effort required to respond to dynamic events in real time, thereby reducing effectiveness of otherwise sound operating actions. Misalignment can also impact system margins. Planning studies define credible limits and operating expectations in order to provide adequate margin for system operation. If these limits

are not verified to be correctly aligned with the current operating capability of the system, the margins defined may be either excessively large or too small, introducing new sources of risk. Excessively large margins may cause the system to be operated closer to its limits and boundaries than is desired, while excessively small margins may limit or unnecessarily restrict operational flexibility and can complicate system operations. From a reliability perspective, misalignment is rarely the result of a single event.

Rather, misalignment can be the result of the sum of many things, including: – evolution of the system; – persistence of assumptions; – timing misalignments between updates and operational implementation of planning decisions. Reliable monitoring of the grid therefore involves the detection of recurring events or patterns, including unanticipated system behavior or persistent discrepancies between planned and actual system operations. The interconnectedness of the Bulk Electric System (BES) magnifies the potential for consequence of misalignment. Differences in assumptions or models for BES planning and operations can create varying understanding and perceptions of BES conditions among parties. These disparate views of system conditions can heighten the potential for uncoordinated BES responses or increased time to restore normal operating conditions in the event of stressed system conditions even when all parties operate within their assigned control areas. Reliability oversight does not consider misalignment as a failure condition per se, but rather as an indicator of potential vulnerability, and aims at identifying the locations where the degree of alignment is decreasing and possibly requiring some form of remedial learning activity or re-assessment. No detailed changes to planning or procedures are required, it is more about bringing awareness to the impact of considering reliability in the risk assessment process. This chapter examined the sources of reliability risk due to the mismatch between planning and real time. This chapter further developed the themes of predictability, margins and coordination to demonstrate the importance of synchronization between different time horizons in order to ensure high reliability of system performance.

End-of-Chapter Summary

Reliability risk is increased whenever there is a misalignment between planning assumptions and real time system conditions, leading to uncertainty, tight margins and coordination challenges. Misalignment of planning assumptions and real-time system conditions can develop over time as the initial planning assumptions become outdated and no longer reflect current system conditions.

Reliability oversight treats misalignment as an indicator of vulnerability (i.e., other than an isolated event) as well as other trends and conditions that indicate a system’s alignment may be deteriorating. This chapter describes why preserving continuous alignment between the Reliability Planning processes and the operations of the BES is important to reliability of the BES.

FROM THE FIELD

The handoff from operational planner to real-time operator is procedural. Programs that improvise the handoff produce inconsistent execution.

Operating shifts overlap with planning briefings. The overlap is intentional. It's where the planner's situational awareness becomes the operator's.

Programs that minimize handoff time as an efficiency measure are optimizing the wrong thing.

Chapter 8

Role of Reliability Coordinators in Bridging Planning and Operations

Reliability Coordinators have a view of the Bulk Electric System (BES) based on planned operations and expected real-time conditions, providing a broad perspective on the BES. Their role necessarily spans several time frames and, therefore, serves as a critical interface between the planning, planning-oriented operations planning activities, and real-time reliability activities. Reliability Coordinator activities serve an integrating function within reliability frameworks, rather than a directing or controlling one. Reliability Coordinators (RCs) use planning derived information to maintain situational awareness of system conditions relative to planning derived system limit capacities, credible contingency robustness, and interarea transfer capacities and sensitivities. This information impacts how wide area system conditions are characterized and the determination of potential reliability threats. While RCs do not perform comprehensive long term planning analyses, their operational effectiveness is highly dependent upon the adequacy, timeliness, relevance and consistency of the planning derived information they receive from Planning Authorities, Transmission Planners and other operating entities. In ERCOT, the Output of Operational Planning is an RLC input that gives insight into the Reliability Coordinator functions. Short term knowledge of the system topology, transfer capabilities and potential constraints is used as an input in the wide-area real-time monitoring and relief activities. The Reliability function is to ensure that operational planning inputs are consistently viewed in the same manner across the grid, focusing on the what is done (techniques are irrelevant) rather than the why. In real-time operations, a Reliability Coordinator combines its planned exposurebased reliability forecast with knowledge of the real-time performance of the grid within its footprint to help discover anomalies in real-time system behavior that may not be readily apparent at the individual power station or distribution level. The Reliability Coordinator brings this knowledge to the attention of other stakeholders and helps to verify that an actual anomaly has occurred. Upon verification, the Reliability Coordinator then begins its analytical work to understand why an

unusual condition may have been observed. One aspect that also points out the importance of consistency between the planning and operational views is the Reliability Coordinator (RC) role. Because of the different assumptions or models used by different Transmission Operators or Balancing Authorities it becomes difficult to agree on any wide-area view of the system state. Reliability comes down to ensuring that there are means to resolve the disagreement, and thus to ensure that there is

some common view of the system state at the wide-area level. The RC’s role is heavily based on communication. The RC communicates planning related information such as forecasting, operational plans and real time information to enable coordination of actions. Reliability oversight is often a view on the effectiveness of the communication to ensure that all parties have a common view of events in real time as opposed to the content of individual orders or alerts. As the Bulk Electric System (BES) continues to evolve, the role of Reliability Coordinators as a “bridge” between different parts of the system will grow in importance. Increasing system complexity, changes in resource characteristics, and decreasing margins for error all argue for a more comprehensive view of the system and a greater understanding of the connections between engineering, operational, and planning decisions that are needed to ensure that planning objectives are carried forward in real time through the system. Reliability oversight considers the Reliability Coordinator role as a defense-in-depth measure that enables synchronization across different time horizons without the need for real-time local control. Reliability Coordinators – Connecting Planning and Real Time This chapter examined the role of Reliability Coordinators in bridging the planning and real-time operations periods. Through the integration of planning-based expectations with real-time knowledge and real-time coordination activities, Reliability Coordinators contribute to systemwide reliability and deal with risk caused by mismatches between planning and real-time.

End-of-Chapter Summary

Reliability Coordinators are a key interface between planning assumptions, planning results and real time system states. With a wide area view, they can identify potential reliability problems early on and act as a coordination mechanism between utilities.

Using consistent planning inputs and mechanisms for communication between time horizons, the Reliability Coordinator can mitigate the effects of differing time horizons without prescribing actions for each entity in the Bulk Electric System. This chapter examines the function of a Reliability Coordinator and its effect on reliability among entities of the Bulk Electric System.

FROM THE FIELD

Operational planning is audited. The standards expect documented procedures, traceable assumptions, and validated outputs.

A finding on operational planning often traces to a documentation gap, not an analytical one. Programs that did the work and didn't document it produce findings.

Self-Reports on operational planning gaps are increasing. Programs that surface their own issues experience different enforcement than programs that don't.

Chapter 9

Planning Horizons, Operational Timeframes, and Reliability Continuity

Reliability of the Bulk Electric System (BES) must be maintained across a broad spectrum of timeframes that vary in terms of horizon, scope, level of certainty, and level of decision-making authority. These timeframes include long-term planning, operational planning, and real-time operations each addressing a different reliability question. However, the ultimate system reliability is the result of reliability being maintained across all horizons. From a reliability framework perspective, the space between these horizons represents a potential reliability weakness, where assumptions, information, or decision making authority may not align. Long-term planning looks to the future and addresses system adequacy and vulnerability, including analyses of future conditions and post-contingency scenarios. The longterm planning activities help to establish hypotheses or assumptions regarding system futures, including potential system capabilities, transfer limits and credible contingencies. Long-term planning does not directly address short-term planning and operational decisions, but rather serves as the analytical basis for the subsequent planning and operational activities. Operational planning is focused on near-term conditions with a lower level of uncertainty. Operational planning uses updated forecast, system model, and resource forecasts to revise assumptions made in the long-term planning process. Reliability continuity is maintained to the extent that the operational planning process captures the intent of the long-term planning process while accommodating uncertainties and unknowns that were not known at the time of the initial reliability planning analysis. Real-time operations are characterized by the narrowest time frame and the most uncertainty. In realtime the operational control of the actual system state is done by using tools, constraints and assumptions generated by the initial preplanning activities. Reliability continuity is preserved as long as these tools, constraints and assumptions adequately represent the present system state and credible contingencies. This category of discontinuities between horizons can occur for a number of reasons including -Assumptions may have been used as the basis for planning and decisions

for a period of time greater than their validity. Decisions based at one horizon may not have been properly accounted for at other horizons. A long term plan outcome or constraint may still be required in the short term operating parameters after there has been a significant change in the system conditions. Reliability oversight will look at the impact (if any) that these types of changes have on operations and overall plant performance rather than trying to pinpoint where in the planning process the decision to

allow these types of discontinuities to occur was made. Yet another challenge to continuity comes from differing objectives at differing timescales. The perspective of long term planning is one of adequacy and sufficiency; that of operational planning, one of stability and security in the here and now. Operation planning bridges this gap in order to transform the vision of the future into the circumstances of the present; the reliability task is one of assessing whether this has been done in a way which does not conflict with continuity, as opposed to simply reinforcing or conflicting with the other differing objectives. Continuity across all horizons is particularly important during stressed system conditions. Events that cover more than one time frame such as periods of prolonged extreme weather or extended outages highlight the need for consistency between planning assumptions and system capability. Reliability oversight verifies that the planning and operational constructs in place support reliable delivery of voltage and continuity of supply throughout the time frames that are of importance to customers. This chapter examined planning horizons and operational timeframes that support reliability continuity. It illustrated the importance of horizon alignment and information flow to ensure that the systems that provide reliable BES performance are in sync across time.

End-of-Chapter Summary

The reliability of the Bulk Electric System (BES) must be considered on a continuous basis across all three horizons: long-term planning, operational planning, and real-time operations. The BES reliability questions that must be addressed in each horizon differ, and misalignment across these horizons can create potential BES vulnerabilities.

Reliability oversight focuses on identifying changes or events that disrupt alignment of plans and expectations across different horizons and determining whether operational plans are designed to bridge the inevitable differences and gaps that inevitably arise

between these horizons. This chapter expands on the need for alignment between planning horizons and operational horizons in order to support reliable operation of the grid.

Chapter 10

Oversight Perspective on Planning and Operations Integration

Reliability oversight examines the interaction of reliability planning and reliability operations from an outcomes-oriented, system-wide perspective. Rather than focus on specific reliability planning studies or operations decisions, reliability oversight addresses the interfaces between Reliability Functions and assesses the reliability of the Bulk Electric System (BES) given a range of assumptions and scenarios. The BES Reliability Oversight provides an integrated, system-wide perspective and focuses on interfaces, consistency and adaptability across Reliability Functions rather than on process steps for compliance with specific Reliability Standards. Integration oversight can be assessed by comparing each other for consistency with planning assumptions, operational planning outputs, and actual system performance. Oversight does not need to be exact to the plan, rather an understanding if any discrepancies are understood, in context, and considered for future oversight efforts. Any inconsistencies or lack of understanding of any discrepancies could be an indicator of reliability risk due to degradation of integration. Ensure that roles and responsibilities within planning and operations are well defined and appropriately bounded. Each Planning Authority, Transmission Planner, Reliability Coordinator and operations organization brings unique expertise to the reliability effort and these contributions are best integrated when carefully coordinated and transitions from one role to another are well understood. Reliability oversight verifies that gaps or excess redundancy in roles and responsibilities have not led to inconsistencies or uncertainties. Another area for focus in oversight is the functioning of feedback systems. The planning and operational planning processes are intended to be dynamic, evolving as a result of lessons learned from operations, changes to the system or to the performance of components. Oversight should verify the presence of a feedback mechanism and that the feedback loop is functioning in a manner that is timely and effective. An ineffective feedback mechanism can allow outof-date assumptions to remain in place, thereby increasing the risk of deviation between planned and actual operational effect. Transparency is a factor in reliability from an oversight perspective. The act of overlooking systems often relies on assumptions about how certain elements of the planning process are carried over into design and implementation, and how the results of implementation are carried back into planning. The reliability of the oversight process can be enhanced by reliable documentation and proven links between design elements, which allow for uninumbergated examination of the system from a policy and political perspective, without need for detailed knowledge of procedural details or algorithms. Reliability oversight retains a non-prescriptive approach to control and management of

means and procedures for integration. It does not: - Instruct entities about their procedures for preparation of and active engagement in operations; - Impose on entities specific measures for coordination. It verifies that the management or control measures in place are adequate to secure the required level of reliability. In this way, oversight is flexible and allows the means and procedures of integration to take account of the evolving characteristics of the system or entity structure. The ongoing modernization of the Bulk Electric System underscores the need for reliability oversight of planning and operations integration activities. Complex systems with reduced reserves and increasingly variable operating conditions are associated with higher risks of reliability performance disruptions, emphasizing the importance of ensuring adequate integration activities. Reliability oversight using observed reliability performance, trends and patterns is an important tool to confirm that any needed integration has been accomplished or to identify areas where additional review and monitoring may be appropriate. This chapter investigated the view from the oversight community with respect to planning versus real-time operations. By focusing outcomes, and the alignment of both planning and operational activities to those outcomes and by focusing feedback within an operational reliability framework, the possibility exists for governance models that are adaptive in nature, while still ensuring reliability is maintained despite changing system conditions.

End-of-Chapter Summary

Reliability oversight assesses how the utility aligns its short-term and long-term plans and ensures that operational activities align with those plans. It evaluates the extent to which operational activities align with the desired level and quality of service defined in the utility’s long-term plans, and assesses operational procedures, staff roles and responsibilities, and communication processes to determine whether they enable operational personnel to perform needed work and make appropriate operational decisions. It also assesses whether operational activities, including those undertaken in response to significant disruptions, are aligned with the intended outcome of the utility’s longterm plans, which includes ensuring reliable service.

By taking a non-prescriptive, outcomes-based approach, oversight monitors through observable trends and patterns in real time rather than through individual decisions. This chapter describes how effective oversight can ensure that plans and actions in the BES remain synchronized over time.

FROM THE FIELD

"Planning is engineering, operations is real-time" — partly true, but the connection between them is the function the standards audit.

"Operational planning is just shorter-term planning" — no. It's a different discipline. Planning Coordinators and operational planners aren't interchangeable.

Chapter 11

SYSTEM EVOLUTION AND INCREASING DEPENDENCE ON PLANNING– OPERATIONS ALIGNMENT

The increased complexity of the Bulk Electric System (BES) has heightened the need for planning and real time operations to be synchronized. Shifts in the composition of resources, their modes of operation and the dynamic nature of the system all add pressure to the points where planning and operations interact. These consequences and interactions are viewed through the lens of the reliability framework where the impact of misalignment to reliability is increased and the need for synchronization and symmetry between time points is more pronounced. In today’s systems, increased variability and frequency of changing operating conditions are the norm. Studies and analyses cover a broad spectrum of possible system states to accommodate greater complexity, and real-time operations experience a higher frequency and degree of uncertainty in system conditions. Operational planning provides a means of dealing with these changes, and reliability supervision verifies that the complexity of the system conditions is adequately translated into the operational context. This module deals with the effects of system changes on planning assumption longevity. Assumptions that were previously valid for extended periods may now need to be updated at a faster pace due to changes in load and/or operating patterns. Reliability continuity planning and operational planning processes must be able to detect when assumptions are becoming outdated and to adjust accordingly. Oversight in this area means that assumptions are being updated and revalidated at a pace that matches the speed of system change. A consequence of this system evolution is an increased level of interconnection between different regions and assets. Power flows, contingency affects, and system sensitivities may now extend well beyond original planning and operational boundaries. This increased level of interconnection emphasizes the need for reliability planners and operations personnel to share a common view of the system as developed by the RCT, TOs and BA’s. Reliability analysis verifies that the planning and operational planning tools for the large, complex system support this common view. Planning– operations alignment is becoming more prevalent as a means to improve reliability.

Margin and buffer analysis is also becoming more important to ensure that reliability control can be achieved. As margins shrink, the effect of planning model errors and planning assumptions on operations become more pronounced. Reliability oversight does not dictate margins or operational procedures, but

rather assesses whether planned margins and procedures are sufficiently large and robust to be able to manage a system in a reliable manner in the event of a credible contingency. System evolution is a further argument for learning-oriented governance. One cannot reliably plan for or react to system changes that are unpredictable in terms of their timing, nature, or likelihood from current system modelling and planning frameworks. Reliability will be enhanced where operational experience is routinely incorporated into system planning, and where planning processes remain agile and dynamic to reflect system changes as they evolve. Oversight in this regard considers whether this adaptive learning occurs in a more systematic fashion rather than on a case by case basis. This chapter examined the implications of WSGE system evolution on reliance on planning-time versus real-time optimization and control activities. It highlighted the ongoing importance of maintaining flexible relationships between these activities and between the short-term and long-term planning horizons in order to effectively manage shared understanding and assumption validation of an changing Bulk Electric System.

End-of-Chapter Summary

Changes in the evolving system require better integration of short-term planning and real-time operations because more recent information is generally needed to prevent decisions from being made with stale information and to preclude the necessity of making separate interpretations for different groups. Such a requirement is due to greater variability, complexity and interdependencies in the system.

Reliability oversight is concerned with whether the system is properly responding to dynamic conditions arising from changing patterns of generation and consumption, shifts in operational planning and real time operations, or changing conditions within the power system itself. This chapter has made a case for sustained alignment and learning-oriented forms of governance as prerequisites to achieving reliability in the increasingly complex and dynamic Bulk Electric System.

FROM THE FIELD

Operational planning is being reshaped by IBR penetration, storage, and demand response. The studies need to model resources that didn't exist when the planning frameworks were designed.

The standards governing planning are revising. The pace is increasing. Programs that build for the direction stay positioned.

Real-time and planning are converging. The horizon distinctions are blurring as the system speeds up.

Chapter 12

Synthesis and Reliability Perspective on Planning and Real-Time Operations

Operational planning and real-time operations are interwoven aspects of the Bulk Electric System (BES) reliability. Planning activities occur before power is transmitted and set the performance expectation for how the BES is expected to behave. The operational planning activity integrates the planning horizon information and the anticipated real-time BES state into a near-term operational perspective, and real time operations ultimately implement the desired BES performance. To maintain reliability, the planning, operational planning, and real-time operations must work together as an integrated whole rather than as distinct activities. One of the underlying themes of this publication has been the importance of consistency between time horizons. The assumptions that go into the planning horizon have to somehow affect or link into the operating limits, tools and procedures and level of situational awareness that people are working with, which in turn affects what is learned and understood from real time operations against the actual behaviours of the system. Reliability oversight starts to see that the interplay between these time horizons affect the learned reliability performance of the systems that are being monitored. There is no single time horizon that should dominate or overlook the others. Rather all must be connected and the connections between them all must be supported and consistent for the desired level of performance to be realized. Operational planning is becoming an increasingly important bridge connecting forecasting and real time operation. Improved operational planning assumptions for current operating conditions help reduce uncertainty and provide operators with a defined framework in which to operate. A timely, transparent and adaptive operational planning process helps ensure high predictability and accordingly enables high quality real-time operational decisions. In the absence of such an effective operational planning process, operational planning can become a point where reliability risk accumulates due to its not being in line with the state of the system. This section also mentions information flow, coordination and situation awareness.

According to the publication, reliable system operation requires that all function elements uniformly interpret the context derived from the system planning, within both the internal system organization and across the organizational boundaries of the system. Disruptions to information flow, or discrepancies in assumptions, can undermine even apparently reliable system element behaviour, and reliability

monitoring and control in these interfaces is more important than at points where apparent individual element decisions are made. Uncertainty management is yet another parameter that keeps on recurring. The reliability framework does not pretend to eliminate uncertainties but manages them via “bailouts”, flexibility and monitoring. Preparation through planning and operational planning for expected variability, as well as the management of unexpected residual uncertainties in real time, are all part of the reliability approach. Increasing operational reliability also implies that lessons learned in operation should feed into the planning cycle and that knowledge sharing becomes a cultural practice rather than an exceptional occurrence. All of these pressure points are being intensified by the ongoing evolution of the grid. Low margins and ever increasing system complexity create high costs when discrepancies between forecasts and real time are not minimized. Reliability analysis based on actual data, trends and patterns ensures that the effectiveness of the integration is sustained in a flexible and non-intrusive manner. Operational planning and real-time operations are integrated in a reliability control that covers from the analytical phase to the execution phase. Their interactions enable to understand how planned, operational and system factors meet or contradict each other. This chapter has summarized the ideas explored in this publication and re-affirmed the fundamental premise that reliable system operation is a function of being aligned, successfully translating planning assumptions to real time and learning across time horizons. From a reliability framework perspective, the relationship between planning and real time operations is not a transaction or event, but rather a function of ongoing governance to ensure BES reliability.

End-of-Chapter Summary

The successful operation of the Bulk Electric System (BES) depends on the continuity of synchronization among three fundamentally interrelated activities - planning, operational planning and real-time operations. Planning establishes the foundation of expected activity among all elements of the BES; operational planning sets out conditions expected to be in place during that timeframe; and real-time operations manage to the uncertain conditions as they actually exist.

Reliability oversight monitors performance and conducts reviews on a spectrum of circumstances from past performance through to future potential events, focusing on outcomes, connection and learning rather than simply compliance. This chapter has reflected on the long term benefits of sustained integrated approaches across time horizons, in the context of developing a dynamic reliability governance system.
