摘　　要：由于分布式电力系统中电源、负荷和线路参数存在不对称性,传统的配电网潮流算法已不适用于这类网络。在对风力发电机组、光伏发电系统、燃料电池、蓄电池、高频微型燃气轮机及工频热电联产机组的运行和控制性能详细分析的基础上,建立各种分布式电源潮流计算模型,考虑配电网三相参数不平衡和环网问题,对广泛用于辐射型配电网的前推回代潮流算法进行改进,提出适用于含多种分布式电源的弱环配电网的前推回代三相潮流算法。算例表明,该文提出的算法是有效和可行的。Traditional power flow algorithms are not applicable to the distribution network with distributed generation because of the unbalance in power source, load and line. Based on the analysis of wind turbines, photovoltaic system, fuel cell, storage battery, high frequency micro turbines and power frequency combined heat and power （CHP）, their models in power flow calculation were presented. In view of unbalance in three phases and weakly meshed characteristics of the distribution network, the back/forward sweep algorithm in power flow calculation was improved, which was widely used for the radial distribution network. A new three phase back/forward sweep power flow calculation for the weakly meshed distribution network with the distributed generation was presented. The example has proved the efficiency and feasibility of the algorithm.
