基于DE算法的电力系统经济负荷分配

摘要

建立了计及发电机阀点效应和网络损耗的电力系统经济负荷分配的数学模型。对优化算法进行了研究，并对微分进化算法（DE算法）以及遗传算法（GA算法）进行对比；提出了DE算法的计算流程；以IEEE3机9节点标准测试系统为例，采用微分进化算法进行测试，计算结果验证了所提算法的有效性。%Establish the mathematical model of the economic load distribution of electric power system, which considering the point effect and generator network loss. This paper studies the optimization algorithm and compares the differential evolution algorithm （DE algorithm） and genetic algorithm （GA）. Puts forward the calculation procedure of DE algorithm. At last, the article puts a test using the method of differential evolution algorithm. The numeric results on 9-bus test system show the effectiveness of the proposed algorithm.
