摘要 为了最大化降低配电网运行中的有功功率损耗,对接入分布式电源(DG)的最优容量和选址进行研究。提出了一种改进的萤火虫算法(FA),通过分析配电网的线路数据,并在萤火虫个体的更新过程中加入淘汰与变异操作,选择有功网损为目标函数。以IEEE-33节点标准测试系统为算例,仿真结果表明,算法具有一定的准确度,改进后的萤火虫算法比传统算法具有更好的寻优速度。 In order to minimize the active power loss in the operation of power distribution network,the optimal capacity and location ofdistributed generation(DG)are studied.An improved Firefly Algorithm(FA)is proposed by analyzing the line data of power distribution network and adding elimination and mutation operation in the update process of individual fireflies,as well as selecting the active power loss as the objective function and taking the IEEE-33 node standard test system as an example.The simulation results show that the algorithm has a certain accuracy,and the improved Firefly Algorithm has a better optimization speed than the traditional algorithm.
