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

Abstract

Abstract. The radial and connectivity of distribution network are the constraint conditions in distribution network reconfiguration. Large numbers of infeasible solutions will be produced in the random search of Quantum particle swarm optimization (QPSO). A quick method for judging the infeasible solution of distribution network reconfiguration is presented in this paper. First, the switches in network are coded based on integer loop encoding rules. Large numbers of infeasible solutions will be eliminated through integer coded. Then, infeasible solutions are divided into two types: loop infeasible solutions and island infeasible solutions. The method named switch -loop matrix and node-layer strategy (NS) for judging infeasible solution is proposed. Finally, the judgment method is tested on IEEE33-bus distributed systems to demonstrate the performance and effectiveness of the proposed method.
