提出了一种基于粒子群优化算法的灵活优化方法,通过合理地确定分布式电源的容量和位置,从优化有功和无功功率损失指数、电压分布指数、MVA容量指数和短路水平指数四方面出发,建立了分布式电源综合效用的多目标函数,并结合38-母线径向测试系统研究了不同独立电压负荷模型情景下分布式电源的最优选址和定容问题。 A flexible optimization method based on Particle Swarm Optimization (PSO) algorithm is proposed. By reasonably determining the capacity and location of distributed power supply, this paper presents four aspects of optimizing active and reactive power loss index, voltage distribution index, MVA capacity index and short circuit level index Based on the 38-bus radial test system, the optimal location and volume capacity of distributed generation under different independent voltage load models are studied.
