Active Distribution Network Reconfiguration Based on Prim Algorithm and Chaos Particle Swarm Optimization

Abstract

According to the character of active distribution network that it could actively control and manage distributed energy resources, this paper puts forward a distribution network reconfiguration method for active distribution network. Because of the random power of distributed generation driven by renewable energy, this paper regards power of controllable load and electrical energy storage as controllable value and takes the effect of V2G(Vehicle-to-grid)into consideration, thus establishes a multi-objective optimization model. Based on knowledge of Graph Theory, this paper proposes a reconfiguration strategy containing island partition, and uses a hybrid algorithm of Prim algorithm and chaos particle swarm optimization to solve the model and optimize reconfiguration project. The validity of the proposed method of active distribution network reconfiguration is verified by simulation results of IEEE 33-node distribution system.
