| Summary: | With the increasing complexity of grid configuration and operation modes as well as the modernization of the international security system and security governance capacity， grid resilience construction has become an important means of improving power security. This study first expounds on the basic concept and characteristics of grid resilience and then reviews the main achievements and lessons drawn from domestic and foreign resilience research， as well as resilience enhancement measures and key technologies. Considering a typical receiving urban distribution network in Beijing as an example， the measures for building a resilient distribution network are outlined based on five perspectives： improving the perception， coordination， adaptability， defense， and resilience. The current resilience level of urban power grids is evaluated based on four aspects： grid， power supply， load， and emergency type. The constraints and challenges facing the future development of urban power grids are clarified based on the following three aspects： supply security， system security， and non-conventional security issues. Finally， the basic technical paths and key technologies for grid resilience construction are discussed， and the key technology layout for improving the resilience level is clarified based on grid characteristics. |
