| 摘 要： | 分析分布式电源接入对配电网络重构的影响对于智能配电网自愈控制的研究具有十分重要的意义.利用配电系统仿真程序OpenDSS,通过IEEE33节点系统的仿真发现分布式电源接入对配电网络重构产生了积极的影响.当网络正常运行时,分布式电源的接入可以提高配电网络重构可行解数量,降低配电网络重构优化解对应的网络损耗,优化了配电网运行.当网络发生故障导致不存在满足网络约束条件的拓扑结构时,分布式电源的接入可以产生网络可行解,从而保障了网络的正常供电.

| Abstract: | The analysis on the impact of DG on distribution network reconfiguration is very important to the research of self-healing control of smart grid. The impact was analyzed in both normal operation and fault condition. Distribu-tion system simulation was performed with the open distribution simulator software（OpenDSS）,and a case study of IEEE33-bus system has reached positive conclusions：in normal operation,the integration of DG increases the num-ber of distribution network reconfiguration feasible solutions and reduces the total network loss of the optimal solution,and thus helps to optimize the operation of the network;while in fault condition,feasible solution can emerge with the integration of DG where there wasn’t any feasible solution originally,and so the integration of DG helps to ensure network power supply. |
