近年来，极端事件(如飓风、地震和洪水)和人为攻击(网络攻击和物理攻击)的频率急剧增加。这些事件严重影响了电力系统，从长时间停电到主要设备(如变电站、输电线路和发电厂)损坏。这就要求制定控制和运行方法以及规划战略，以提高电网对此类事件的复原力。迈向这一目标的第一步是制定复原力指标和评估方法，以比较规划和行动备选方案，并为增强复原力提供技术经济理由。虽然在文献中已经提出了几种电力系统弹性的定义、度量和评估方法，但这些定义、度量和评估方法尚未被普遍接受或标准化。本文对当前电力系统弹性度量和评估方法的实践进行了全面和批判性的回顾，并讨论了未来的方向和建议，以促进普遍接受的和标准化的定义、度量、评估方法和增强策略的发展。本文深入分析了不同组织和学者对电力系统复原力概念的共识，以及现有和目前正在实践的复原力增强方法。还提供了研究差距、相关挑战以及针对现有限制的潜在解决方案。
The frequency of extreme events (e.g., hurricanes, earthquakes, and floods) and man-made attacks (cyber and physical attacks) has increased dramatically in recent years. These events have severely impacted power systems ranging from long outage times to major equipment (e.g., substations, transmission lines, and power plants) destructions. This calls for developing control and operation methods and planning strategies to improve grid resilience against such events. The first step toward this goal is to develop resilience metrics and evaluation methods to compare planning and operation alternatives and to provide techno-economic justifications for resilience enhancement. Although several power system resilience definitions, metrics, and evaluation methods have been proposed in the literature, they have not been universally accepted or standardized. This paper provides a comprehensive and critical review of current practices of power system resilience metrics and evaluation methods and discusses future directions and recommendations to contribute to the development of universally accepted and standardized definitions, metrics, evaluation methods, and enhancement strategies. This paper thoroughly examines the consensus on the power system resilience concept provided by different organizations and scholars and existing and currently practiced resilience enhancement methods. Research gaps, associated challenges, and potential solutions to existing limitations are also provided.
