Resilience (power system)

Definitions for power system resilience vary, but a commonly cited definition was proposed by the Federal Energy Regulatory Com- mission (FERC), which defines it as ”the ability to withstand and reduce the magnitude and/or duration of disruptive events, which includes the capacity to anticipate, absorb, adapt to, and/or rapidly recover from such an event". Attributes that define a resilient system are, for example, predictive capacity, robustness, adaptability, rate of recovery and adaptive capacity. All systems have different vulnerabilities, and resilience is therefore studied in both a system- and event-specific manner. The event scope for resilience is often defined as high-impact low-probability events, or extreme events. However, as extreme climate-related events and cybersecurity events have grown more common, a more universal definition is that resilience deals with n-k, k>5 events.
