| Summary: | 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. |
