摘　　要：分布式电源是智能电网的重要组成部分。针对配电网中分布9式电源优化配置问题,文章建立了两阶段多维动态模型,即第一阶段通过计算并甄选节点电压-网损灵敏度,以降低网损为目标进行分布式电源选址;第二阶段考虑配置成本和系统可靠性建立目标函数,通过仿电磁学算法进行分布式电源定容。同时,为了改善第二阶段中使用的仿电磁学算法的性能,对该算法在合力计算、粒子更新和局部搜索方面加以改进,提高了算法的寻优能力和收敛能力。最后通过IEEE39节点系统进行仿真及结果分析,表明此方法在分布式电源优化配置中得到了较好的结果。Distributed Generators （DG） is an important part of smart grid. To solve the optimization allocation prob- lem of distributed generator, this article put forward a two-stage multidimensional dynamic model, which calculated and selected node loss-voltage sensitivity for DG site selection in order to reduce network loss in its first stage. Consid- ering allocation cost and system reliability, this article use the Electromagnetism-like Mechanism（ELM） algorithm for DG capacity selection in the second stage. In order to improve the performance of ELM, this article mainly improved force calculation, particle update and local search, ＇which can enhance the convergence and optimization efficiency of the ELM. Finally, through the IEEE39 node system simulation and result analysis, it shows that good results obtained in optimization allocation of DG.
