Distribution Network Reconfiguration Based on Particle Swarm Optimization and Chaos Searching

As the connection between transmission network and consumers facilities, distribution network has been paid more and more attentions about its planning.A scientific and efficient optimization project for distribution network structure can save investment,reduce power-cutting and the line losses, as well as improve the quality of electric power,which is currently one of the important task of the departments of power system.This paper introduces chaos into the distribution network planning,and a new planning method is based on the particle swarm optimization. A restoration scheme is given aiming at the problem of production of the lots of infeasible solutions due to the application of the genetic algorithm in distribution network planning.And the improved forward-backward sweep method of distribution network is given based on analytic network process.The restlts from calculation example shows that the proposed method is effective.
