Evaluation of Power Systems Resilience to Extreme Weather Events: A Review of Methods and Assumptions

An Evaluation of Sustainable Power System Resilience in the Face of Severe Weather Conditions and Climate Changes: A Comprehensive Review of Current Advances

“…This has resulted in the classification of planning into long-term and short-term categories, further delineated into hardening and operational approaches, contributing to the evolution of larger and smarter power systems [38]. Enhancing resilience goes beyond achieving the fastest system recovery; it involves fortifying the system in four distinct aspects, including robustness, resourcefulness, rapid recovery, and adaptability [1,43,44]. The planning and preparedness for a power system are devised with these considerations in mind.…”

“…In recent times, assessment and improvement techniques for power system resilience have gained considerable traction due to amplified concerns stemming from high-impact low-frequency events. These events are recognized for their rapid and devastating nature, leading to widespread damage across multiple components over expansive regions [1,2]. A survey conducted by the United States Government Accountability Office (GAO) presented findings on the profound impact of climate change on the resilience of the power system in 2021.…”

Metrics and Strategies Used in Power Grid Resilience

“…Resiliency definitions [1][2][3][4][5] Resiliency enhancement [1,2,[6][7][8] Resilience metrics or indices [1,3,9,10] Resilience Cyber-physical [9,[11][12][13]] Extreme events [2,5,[7][8][9] Most of the methods used in studies to define the states of the power grid are based on physical models and the analysis of its infrastructure. However, this approach is unsuitable for handling the increasing uncertainty in the new variables that add complexity to the system.…”

Research on the construction of a “full-chain” rapid response system for power emergencies

“…Kapucu, with Hurricane Katrina and other natural disasters as empirical evidence, discusses and reveals the existence of the problems and shortcomings in the United States of America emergency management joint agreement [ 10 ]. Francis et al evaluated the resiliency of the power system in the event of emergencies and offered measures to improve its resilience [ 11 ]. Only with the occurrence of emergencies and the growth of the reform and opening-up policies have Chinese scholars begun to pay attention to emergency management.…”
