摘要

配电网供电恢复后

为实现多微网内各区域自治系统稳定及快速有序地并入配电网

提出一种考虑稳定性和联网时长的单相/三相(简称单三相)混合供电制式多微网联网路径搜索算法及源荷储恢复策略:基于单三相混合供电制式多微网图论模型

将联网路径搜索转换成最小生成树问题

利用改进Prim算法进行最短路径搜索;联网完成后

通过基于混合整数规划的粒子群算法

将多微网区域自治时被切除的次要负荷、被限制的新能源出力以及储能电池的电量进行集中式恢复。基于DIgSILENT的单三相多微网仿真平台对所提算法进行仿真验证

证实了所提算法的有效性和实用性。

Abstract

For the realization of each regional autonomous system within single-phase/three-phase multi-microgrids(TP/SP MMGs)reconnected to the distribution network steadily

fleetly and orderly

a connected sequential path search algorithm applied to TP/SP MMGs which considers the time of synchronism check and stability is proposed. Based on the TP/SP MMGs graph model

the connected sequential path search problem can be transformed into a minimum spanning tree problem

and the improved Prim search algorithm is used to search the minimum tree. After the success of reconnection to the distribution network

the particle swarm optimization algorithm based on mixed integer programming is executed to centrally recover the removed minor loads

confined new energy output and electric quantity of energy storage battery. Finally

the proposed algorithm is verified by the platform of multi-microgrids with single-phase/three-phase architecture based on DIgSILENT

which proves the validity and practicability of the proposed algorithm. This work is supported by National High Technology Research and Development Program of China(863 Program)(No. 2014AA052001)and Key Laboratory of Clean Energy Technology of Guangdong Province
