Review and Rethink of Power System Resilience Against Extreme Weather Events: Current Practices, Challenges, and Future Trends

Extreme weather events with low probabilities but high impacts can cause widespread power outages. This necessitates that power systems must be capable of resisting, adapting to, and recovering from severe disruptions caused by extreme weather events, i.e., resilience. Research into the resilience of power systems against extreme weather events is still ongoing, seeking to identify the causes of power outages, assess their socioeconomic impacts, and explore ways to harden power systems. This paper first outlines the basic concept and research framework of power system resilience. It then consolidates and reviews the progress of the research field, including socioeconomic resilience metrics, resilience assessment methods, and resilience reinforcement strategies. Based on a comprehensive literature review, we also point out current research challenges and suggest future research trends.
