| 摘 要： | 随着分布式电源(distributed generation,DG)在配电网中安装比例逐年增加,配电自动化应加强对DG的优化调度功能,发挥DG对配电网优化的有利作用。配电网重构是配电网优化的重要措施,DG联网后,DG注入配电网功率直接影响配电网重构结果。为使配电网性能达到整体最优,提出了一种基于粒子群优化算法(particle swarm optimization,PSO)的配电网重构和DG注入功率综合优化算法。该算法根据PSO并行计算的特点,采用PSO和二进制粒子群优化算法(binary particle swarm optimization,BPSO)相结合的方式,对转换开关状态和DG注入功率2种控制变量同时处理,达到配电网网损、电压偏差最小的目的。将DG作为可调度设备,对配电网重构和DG注入功率进行综合优化,提高了含DG配电网的电能质量和供电可靠性。将该算法应用到3馈线配电系统,仿真结果验证了所提算法的有效性。

| Abstract: | Due to the increase of distributed generation (DG) installed in distribution network with years,it is necessary to enhance the optimal dispatching of DG in distribution automation to play the favorable role of DG in distribution network optimization. Distribution network reconfiguration is an important measure for distribution network optimization,after the grid-connection of DG the power of DG infected into distribution network directly influences the reconfiguration result of distribution network.
