摘　　要：网络重构和电容器投切组合是配电网络综合优化的两个重要内容,区别以往综合优化时采用先重构后投切的交替迭代模式,将开关状态变量和电容器投切组数同时作为控制变量,采用统一同步求解模式,在此基础上针对二进制化改造的差分进化算法,对其控制参数进行了自适应优化改进,并将其应用到配电网综合优化中。算例结果表明了对配电网络进行综合优化的有效性,同时也反映了改进二进制差分进化算法的优越性。Network reconfiguration and capacitor switching are two main measures to realize comprehensive optimization of distribution networks. Different adopting reconfiguration prior to capacitor switching in the conventional comprehensive optimization, the switch state and the number of switched capacitor banks were both taken as the control variables and given the unified solving mode. Based on that, the improved binary differential evolution （DE） algorithm was used to optimize the self-adaptability of the control parameters. The new algorithm was applied to compre- hensive optimization of the distribution network, and the calculation example proves it effective.
