摘要
分布式电源逐渐高比例接入已成为城乡配电网发展的趋势,源、荷、自然环境等各种不确定性因素带来的各种扰动不可忽略,因此配电网需要具备一定的抵御不同扰动并能快速恢复的能力,这种能力被称为配电网韧性。同时,配电网源网荷储各侧灵活性资源可为配电网供需平衡和韧性提升提供一定支撑。如何准确刻画各类扰动事件的影响、有效挖掘源网荷储各侧灵活性资源的协同作用,是研究配电网韧性的关键问题。文章旨在对新型配电网规划、安全稳定运行以及韧性研究给出一定的建设性的思路。首先,介绍了配电网韧性的基本概念,分析了配电网所面临的各类扰动及扰动下配电网韧性特征;随后,归纳了极端灾害类扰动和波动类扰动建模方法和韧性评估方法的研究进展;接着,介绍了配电网在扰动前、中、后三阶段下韧性提升的关键技术;最后,对未来配电网韧性待研究的关键问题进行了展望。
The development trend in urban and rural power distribution networks is to gradually access a high proportion of distributed power sources.However,the various types of disturbances caused by uncertain factors,including power sources,loads,and the natural environment,cannot be ignored.Therefore,the distribution network must have the ability to resist various disturbances and recover quickly,which is called the resilience of the distribution network.Meanwhile,all types of flexible resources from the source,network,load,and storage of distribution networks can provide support for the balance between supply and demand,and improvement of toughness of the distribution network.Accurately describing the impact of various disturbance events and effectively determining the synergy of flexible resources on the source,network,load,and storage sides are key factors in studying the resilience of distribution networks.This study aims to provide insights and constructive ideas for the planning,safe and stable operation,and resilience research of new distribution networks.This study first introduces the basic concept of distribution network resilience,and analyzes various types of disturbances faced by the distribution network and the characteristics of distribution network resilience under disturbances.The study then summarizes the research progress in extreme disaster disturbances,wave disturbance modeling methods,and resilience evaluation methods.Next,the key technologies for improving the resilience of distribution networks in the pre-disturbance,mid-disturbance,and post-disturbance stages are also introduced.Finally,the key problems in the future research on distribution network resilience are discussed.
