摘　　要：优化低压电网拓扑结构,有效利用电能是太阳能光伏供电系统研究中的重要课题.首先将太阳能光伏电站的供电范围用K-means聚类算法分成若干个较小区域,然后在每个区域内用改进的最小生成树算法进行网络拓扑结构优化,从而完成了对整个太阳能光伏供电网络的整体优化.仿真结果表明,优化后的低压供电网络有效降低了供电线损,提高了光伏系统电能的利用率.To optimize the topology of low-voltage network so as to take advantage of electric power efficiently is of importance to the research on solar photovoltaic power systems. An approach is therefore presented that the power supply zone of a solar photovoltaic power station should be divided into several subzones by the K-means clustering algorithm, then the topology of network is optimized with the improved Simulation results showed that the line improved greatly the utilization of electric minimum spanning tree algorithm in every subzone. loss of low-voltage network decreases, which thus power
