摘　　要： 随着能源危机和环境挑战,越来越多基于包含小水电的分布式电源并入配电网运行。为了充分利用小水电的发电能力,分析了小水电群的运行特性,提出了计及电容器投切约束和小水电弃水的优化控制方法与策略,利用改进的PSO智能算法进行目标的优化求解。利用IEEE9节点系统对该方案进行测试仿真计算,结果表明该算法能够很好地获取全局最优解。该方法可应用于含有小水电等分布式电源的配电网优化运行分析中。 With the energy crisis and environmental challenge,more and more distributed generation（DG）based on small hydropower station has been connected to the distribution network.In order to make full use of the small hydropower exploitation capacity,the operation characteristics of small hydropower station are analysed,and an optimization control method and strategy containing the capacitor-switching limitation and the water discharge of small hydropower station is proposed.A new intelligent PSO algorithm is proposed to solve this objective optimization of small hydropower.The proposed method is tested by IEEE 9-bus system,the investigations reveal that method is capable of obtaining global optimal solutions efficiently.The satisfying result shows that the method proposed can be used in the optimal operation analysis of distribution network with distributed generations such as small hydropower station,etc.
