摘　　要：在配电网电源充裕的前提下,通过调节可控分布式电源的功率输出来优化配电网运行,稳定节点电压,降低线路损耗.结合PQ控制理论,通过调节分布式电源的功率因数来控制分布式电源有功功率和无功功率的输出.利用粒子群算法求解可控分布式电源的最优功率因数值,智能优化配电网运行.最后选取IEEE33节点配电系统进行算例分析,以验证该方法的有效性.In the condition of sufficient distribution network power operation of the distribution network is optimized by adjusting the power output of the controllable distributed generation, including stabling node voltage and reducing line losses. By adopting PQ control theory, the active and reactive power output of distributed generation can be controlled by adjusting the power factor of distributed generation. The optimal power factor of distributed generation is searched by particle swarm algorithm. Finally, the effectiveness is verified by the simulation results of IEEE 33-bus system with D Gs.
