Abstract: In order to improve the economy and stability of distribution network with DG, an optimal reconfiguration model of distribution network with DG is established by using multi-objective weighting method with the minimum sum of system loss and node voltage deviation as the comprehensive objective function. The wolf colony algorithm is improved by using Levy flight and adaptive step size, which reduces the number of iterations and improves the convergence performance of the algorithm. The improved wolf colony algorithm is used to solve the optimization reconfiguration model of distribution network with DG. The analysis results of the example show that the reasonable access of distributed generation and distribution network reconfiguration can effectively reduce the network loss and improve the node voltage, which verifies the correctness and superiority of the distribution network reconfiguration method proposed in this paper.
