Reliability, Resilience, and Probability Applications (RRPA) Subcommittee, Task Force on Power System Resilience Metrics and Evaluation Methods
The North American Electric Reliability Corporation (NERC), which is responsible for developing reliability standards for the bulk power system, defines reliability in terms of two fundamental concepts. It should be robust enough to be reliable and have the ability to predict and prepare for potential outages. A resilient EPS should ensure an uninterrupted power supply, even in the face of minor faults and major disruptive events. Regardless of the reasons, one growing concern https://bookaustraliatravel.net/what-are-the-benefits-of-a-carbon-neutral-australian-getaway/ is that power outages result in economic losses and hardship for people who have become increasingly reliant on electricity for even basic comforts. As these events are rare, there is limited data available on their effects, which makes calculating the risks of the events challenging.
Additionally, the interdependence of different infrastructures, such as energy, transportation, and communication, can exacerbate the impact of a disruptive event. High-impact low-probability events can be caused by for example, extreme weather, human error, ageing infrastructure or cyberattacks. The generation of high-resolution climate information by applying empirical relationships, established from historical data, between large-scale climate variables and local weather conditions.
- In the United States, electric utility firms have registered over 2500 significant power outages since 2002, with almost half of them (specifically 1172) attributed to weather events, including storms, hurricanes, and other unspecified severe weather occurrences.
- Distributed energy resources are rapidly growing in some states, but most U.S. customers will continue to depend on the large-scale, interconnected, and hierarchically structured electric grid.
- In this Review we argue that resilience must be redefined as a long-horizon, event-independent property that governs power system performance across the range of futures a system may encounter.
- All authors made a substantial contribution to the discussion of content and reviewed early versions of the article.
- There is no single solution that fits all situations when it comes to avoiding, planning for, coping with, and recovering from major outages.
Resilience of renewable power systems under climate risks
Analytical methods in which constraints are required to hold with a specified probability rather than under all conditions. A post-processing step that adjusts climate model output so that its statistical properties match those of observed data over a reference period. We formulate this concept of long-horizon resilience, set it against the event-based paradigm it replaces and develop a unified https://clomidxx.com/wind-and-solar-power-forecasting-innovation/ framework for studying, gauging and reinforcing it.
Resilience Metrics Development for Power Systems
The goal of this report is to provide a road map for standardizing resilience metrics for power grids that align with ongoing industry efforts and regulatory requirements. Distributed energy resources are rapidly growing in some states, but most U.S. customers will continue to depend on the large-scale, interconnected, and hierarchically structured electric grid. These “smart grids” use improved sensing, communication, automation technologies, and advanced metering infrastructure. The use of automation at the high-voltage level can improve grid reliability, but also introduces cybersecurity vulnerabilities.
Therefore, strategic resilience planning for mitigating the negative effects of future events requires a comprehensive approach that considers a range of potential disruptive events and their potential impact across the power system infrastructure. Therefore, strategies to enhance electric power resilience must consider a diverse set of technical and institutional arrangements and a wide variety of hazards. However, the planners and operators of the system have made great efforts over many years to ensure that the electric system is engineered and operated with a high level of reliability.

In this Review we argue that resilience must be redefined as a long-horizon, event-independent property that governs power system performance across the range of futures a system may encounter. As extreme weather evolves and its uncertainties compound across decades, resilience measured event by event becomes variable and difficult to interpret, and offers no reliable basis for long-term planning. The report also identifies research gaps and future directions to enhance resilience measurement methodologies. The use cases presented in this report demonstrate how these metrics can be applied in practice and highlight their relevance across different decision-making contexts.

Resilience is not just about preventing these outages from happening, but also limiting their scope and impact, restoring power quickly, and preparing for future events.
The Committee on Enhancing the Resilience of the Nation’s Electric Power Transmission and Distribution System has developed strategies that seek to reduce the impact of large-scale, long-duration outages. In the United States, electric utility firms have registered over 2500 significant power outages since 2002, with almost half of them (specifically 1172) attributed to weather events, including storms, hurricanes, and other unspecified severe weather occurrences. Climate-related issues have intensified the attention on energy sustainability and resilience. It also encompasses the ability to rebound and cope with outages effectively by reducing their impacts, regrouping quickly and efficiently after the event ends, and learning to handle future events better. For example, a severe storm can knock out power to a large geographical area, while a cyberattack on the communication systems can disrupt the entire power grid.
