摘　　要：随着电网形态和运行方式的日益变化,以及国家安全体系和安全治理能力的现代化,电网韧性建设成为提高电力安全水平的必要手段。首先,通过阐述电网韧性的基本概念和特征,综述了国内外韧性研究的主要成果和经验教训,回顾了韧性增强的典型措施和关键技术。然后,以典型受端城市配电网为例,从提升配电网的感知力、协同力、应变力、防御力和恢复力5个角度,概述某典型城市进行韧性配电网建设的典型措施;从网架、电源、负荷与应急手段4个方面评估电网韧性水平现状,从供应安全、系统安全和非常规性安全问题3个方面明确城市电网未来发展面临的制约和挑战。最后,讨论电网韧性建设的基本路径和关键技术,基于电网特性明确提升韧性水平的关键科技布局。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.
