Distribution Network Reconfiguration Based on Differential Evolution Algorithm

Abstract

On the base of the special configuration of distribution network, solved generating a large number of infeasible solutions in reconfiguration of distribution network by using cyclic coding strategy, this paper proposed corresponding decimal encoding and its mutation, crossover and selection operators. For the previous discussion about radial structure decision, further cleared its definition, figured out the issue that reverse of current flow in part of network branches after reconfiguration, and finally simulate the IEEE 33-bus system based on differential evolution algorithm. The result shows that the method proposed is fast and effective.

A Quick Judgment Method for the Infeasible Solution of Distribution Network Reconfiguration

“…[6] puts forward a new decimal encoding genetic algorithm coding rule. As decimal encoding can solve the problem that binary encoding generate most infeasible solutions, so it is applied to differential evolution algorithm [7] and improved immune genetic algorithm [8].However, the evolution or crossover progress also produce most infeasible solutions. So just rely on decimal encoding can't completely solve the problem of infeasible solutions and research of the infeasible solution judgment method is still a important topic.Based on existing researches, the method named switch -loop matrix and node-layer strategy (called SLNS for short) based on integer loop encoding for judging infeasible solution is proposed.…”
