Abstract: Power systems are the backbone of modern society, but high-impact and low-probability natural disasters pose unprecedented challenges to power systems in recent years. Power systems consist of generation, networks, and loads, which have their own characteristics. Different sectors need to various responses and strategies in the face of natural disasters. This paper presents a systematic review on power system resilience from four dimensions: (1) Impact analysis. In this dimension, typical disaster-related power outages are quantitatively analyzed, and the impacts of the events on the power systems from the perspective of generation/networks/loads are qualitatively analyzed. (2) Impact quantification. The quantification metrics of the impacts of different events on generation, networks, and loads are systematically reviewed. These systematical quantification metrics are essential prerequisites for resilience improvements. (3) Resilience improvement. Adaptation options from the component-level perspectives are first introduced, and then the optimal strategies from the system-level perspectives are presented. Various power sources have different power production characteristics against different kinds of natural disasters, and coordinated scheduling of different power sources is an effective means to improve generation resilience. System networks are important to bridge generation and loads, and they need to have strong resilience in the face of varying and uncertain impacts caused by natural disasters with system hardening, reconfiguration implementation, microgrid formulation, etc. Loads are becoming more smart and responsive, and these smart/responsive loads have outstanding potential regulating abilities for improving power system resilience. (4) Future research directions with regard to power system resilience improvements are discussed.
