A State-of-the-Art Literature Survey of Power Distribution System Resilience Assessment

With increased threats from frequent natural disasters, power distribution network resilience has been gaining momentum in recent years. In the literature, a variety of methods have been proposed for assessing the resilience level of the power distribution system. This paper conducts a comprehensive review of the state-of-the-art methods on resilience evaluation framework and metrics in the literature. At first, the core conceptions of the resilience are clarified, and different phases before and after the incidents are analyzed. Subsequently, evaluation methods are classified into several categories based on their features and limitations, and reviewed respectively. Finally, challenges and promising topics in this area are discussed and summarized. The value of this paper is to gain a deep insight into this import research area and envision some future works, which can assist the operator/planner to formulate more effective restoration strategies and produce more effective countermeasures to increase the resilience of distribution network.
