“…The term is rooted in economics and has been applied in financial management to measure the consequences of adversity those may or may not be of monetary value. According to the 2007 grant guidance of the Homeland Security Grant Program (HSGP) in the USA, the risk is defined as the product of the probability of attack, vulnerability, and measure of consequences [19]. In power systems, the risk of an event is measured by

normalRisk = normalProbability normalof normaloccurence \times normalSeverity normalof normalevent .

Different risk indices like overload risk index, low voltage risk index, and loss of load risk index have been proposed [18].…”

Modern societies these days are more dependent on electrical energy and they expect a continuous supply as per demand. In this regard, the complex power system is designed to supply electrical energy with a certain level of quality and continuity though it is still susceptible to vandalism, natural disasters, and extreme weather. The black sky event where the power grid goes down is more of a possibility nowadays than ever due to more frequent severe weather events. This in turn has increased the need to study resilience in the context of the power system. This study presents a comprehensive review of the literature on power system resilience from various perspectives. First, well‐developed power system safety concepts are discussed and critically reviewed in view of large‐scale power outages. Then, the various definitions and confounding features of resilience in the power system domain are presented. Subsequently, several frameworks, resilience curves, and quantitative metrics proposed in recent years for power system resilience are investigated, followed by a summary of hardening strategies. Next, a case study is presented to illustrate how the resilience of a 69‐bus system is assessed against a hurricane. Finally, the study highlights challenges and proposes several future works to achieve a resilient power grid.
