This paper presents an effective network reconfiguration method for distribution of distributed photovoltaic power to minimize the active power loss in the distribution network. An improved binary particle swarm optimization(SPSO) algorithm is proposed to solve the problem of network reconfiguration. Based on the sensitivity analysis, the distributed photovoltaic power source is optimally configured. The simulation test proves that the proposed method can reduce the power loss and bus voltage drop through the network reconfiguration and optimization configuration on the IEEE 33 distribution network at three different load levels and shows a better performance compared with other algorithms Excellent performance.
