摘　　要：基于配电网中含有分布式电源(DG)以及其辐射状的网络特性,提出了一种层次网络分解的配电网孤岛划分方法。该方法将配电网的支路按结构进行分层,形成层次矩阵、层次支路两端的节点矩阵以及层次之间相连的关联矩阵,通过层层删减层次矩阵的支路连接实现自上而下的网络搜索,可以减少网络搜索的复杂度。根据孤岛划分的原则,利用层次网络分解方法,对配电网络进行自上而下的孤岛划分方案搜索,以确定满足约束条件的孤岛方案。IEEE 69节点配网的仿真结果表明,所提出的算法能生成合理的孤岛划分方案。Based on the distribution network containing distributed generator and its radiating characteristics of network, a hierarchical network decomposition method for distribution network islanding was presented. The branch of distribution network according to the structure to form the level matrix was stratified, node matrix that due to the ends of level branch and correlation matrix connected to each levels. A top-down web search was implemented through layer upon layer cut network branch connection. What＇s more, the complexity of the network search was reduced greatly. Based on islanding principle, a network decomposition method was used to search out all the islanding solutions of the distribution network from top to bottom, and then determines an optimal islanding solution which satisfies the constraint condition. Simulation results based on IEEE 69-node distribution system demonstrate that the proposed algorithm can generate a reasonable islanding solution.
