摘　　要：为了更合理地将分布式电源并入配电网中,提出考虑配网结构变化影响的DG规划。首先采用损耗灵敏度因子对DG进行最优布置,然后建立了以最大减少系统网损为目标的网络重构与DG容量配置的综合优化模型,并通过改进的细菌觅食算法对所提模型进行求解,最后用IEEE33和IEEE69节点系统进行仿真计算。计算结果表明,考虑配电网结构变化的DG规划更加实际、有效。In order to connect DG to distribution network more reasonably, a new method of DG planning considering the variation of the distribution network structure is put forward. Firstly, this paper uses the loss sensitivity factor to get the optimal layout of DG. To minimize the system loss, the comprehensive optimization model is built to configure the network reconstruction and DG capacity. Secondly, the improved bacterial foraging algorithm is used to solve the proposed model. Finally, the IEEE33 and IEEE69＇s node system are used for simulation calculation. The calculation results indicate that the DG planning considering the variation of the distribution network structure is more practical and effective.
