Blackouts, Restoration, and Islanding: A System Resilience Perspective

The resilience (or resiliency) of a system is characterized by its resistive, anticipative, absorptive, adaptive, and restorative capacities when facing adverse events. Resilience is an umbrella term that goes beyond related concepts like robustness and protection, redundancy and fallback options, or reliability. A system is considered resilient when it can provide a high level of service, even after highimpact, low-probability events. For every system, resilience regarding a specific event can be analyzed by studying the system's performance over time.
