在当前能源与环境问题日趋严重的背景下,分布式能源被越来越多的人所重视.但是,由于分布式电源自身的特性,以及其间歇性的随机、波动特性,使传统配电网络的灵活性不足,给电网的安全稳定运行带来了极大的挑战.近年来,智能电网等相关技术的发展与应用,使配电网络呈现出一种开放性的特点.但是,在新能源占比不断增加的同时,新能源接入也给配电网络带来了诸多负面效应.主动配电网络(Active Distribution Network,ADN)就是为解决上述问题而提出的.在主动配网中,新能源接入可使其具有更高的灵活性与高效性,并有效提升其安全稳定程度,降低其对传统电网的冲击.基于此,对ADN在规划、运行过程中面临的问题与挑战进行了分析.
Analysis of Key Technologies for the Planning and Operation of Active Distribution Networks
Against the current backdrop of increasingly serious energy and environmental issues,distributed energy resources are being increasingly valued by more and more people.However,due to the own characteristics of dis-tributed power sources and their intermittent random and fluctuating characteristics,traditional distribution net-works lack flexibility,which poses great challenges to the safe and stable operation of the power grid.In recent years,with the development and application of related technologies such as smart grids,the distribution network has shown an open characteristic.However,as the proportion of new energy continues to increase,new energy integra-tion has also brought many negative effects to the distribution network,and the active distribution network(ADN)is proposed to address the above issues.In the ADN,new energy integration can make it more flexible and efficient,effectively improve its security and stability levels,and reduce its impact on traditional power grids.Based on this,the article analyzes the problems and challenges faced by the ADN in the planning and operation process.
