Reconfiguration of Distribution Network Base on Differential Evolution Algorithm

配电网重构是降低电力系统中网络损耗的主要途径。将微分进化算法应用于配电网重构中,通过改变开关的闭合状态来改变网络的拓扑结构,从而达到网损最小的目的。并通过两种不同的智能优化算法对IEEE33节点系统进行仿真测试,测试结果表明:微分进化算法具有收敛速度快、鲁棒性好、计算精度高等特点。

Reconfiguration of distribution network is the primary means of reduce the network loss in the electric power system. In this paper, differential evolution algorithm was applied to the reconfiguration of distribution network. In order to acquire minimum network loss network topological structure was changed through altering switch closing. And through two different types of intelligent optimization algorithm IEEE33-bus system simulation testing, the results showed that differential evolution algorithm has fast convergence and better robustness and high accuracy.
