摘　　要：针对含分布式电源(Distributed Generators,DG)配电网络优化运行的问题,进行了配电网重构优化算法的研究,对含有DG的配电网络应用改进二进制粒子群优化算法进行重构,建立基于多种负荷方式(最大、最小、一般负荷方式)的配网重构模型,建立计及DG的配网辐射状判定依据,并对配电网潮流计算进行了改进,使其适用于拓扑结构变化频繁的网络。最后运用IEEE33节点测试系统对所提算法进行仿真验证,结果表明所提优化算法可使含DG配电网络的网络损耗明显降低,在一定程度提升系统的电压水平。As to the problem of the optimal operation of distribution network with distributed generators（DG）, distribution network reconfiguration optimization algorithm is studied, an improved binary particleswarm optimization algorithm reconstructed the distribution network with DG is used, the distributionnetwork reconfiguration model is established which based on a variety of load mode （large, small, mediumload mode）, established radiate judgment basis of distribution network with DG, the power flow falculationof distribution network is improved, making it applicable to the network which topology changes frequently.Finally, IEEE33 node test system is used to simulate theproposed optimization algorithm of distribution networkenhance the voltage level of the system certain extent.proposed algorithm, the results showed that theincluding DG can significantly reduce losses,
