摘　　要：台风、暴雨和地震等极端事件愈加频繁发生,严重停电事故暴露了配电网应对灾害能力的不足。为减少极端灾害造成的配电网故障问题,配电网韧性评估与提升研究具有重要的理论价值和现实意义。首先,简要介绍了韧性定义,将韧性与可靠性、安全性、鲁棒性进行归纳区分。然后,依据评估方法的不同侧重点对韧性指标进行分类,梳理了韧性评估指标体系。针对提高配电网韧性这一问题,基于极端天气量化分析和配电网故障建模,分别对配电网灾前、灾中、灾后三阶段韧性提升策略进行论述。最后,从故障表征、韧性评估及韧性提升3个方面出发,探讨了未来配电网韧性研究领域的关键问题和发展方向。Extreme events such as typhoons,heavy rains,and earthquakes are occurring with increasing frequency,revealing the inadequacies of the distribution network to respond to disasters.To mitigate distribution network failures caused by extreme events,research on the assessment and enhancement of distribution network resilience is of significant theoretical and practical importance.This article begins by providing a concise definition of resilience and distinguishes it from related concepts such as reliability,security,and robustness.Subsequently,it classifies resilience indicators based on various assessment methodologies and organizes a resilience assessment index system.To address the challenge of enhancing distribution network resilience,this article discusses three-stage strategies for improvement before,during,and after a disaster,based on quantitative analyses of extreme weather and fault modeling of the distribution network.Finally,key issues and future development directions in the field of distribution network resilience research are explored,focusing on fault characterization,resilience assessment,and resilience enhancement.
