Optimal Distribution Network Reconfiguration to Improve the System Performances using PSO with Multiple-Objectives

摘要

This This paper presents an effective method to find the optimal reconfiguration of the distribution system to reduce the active and reactive power losses, voltage deviation and to enhance the reliability of the system. The optimal reconfiguration is proposed based on a multi-objective function which includes active and reactive power loss index, voltage deviation index and reliability index using Particle Swarm Optimization Technique (PSO). Here we have considered IEEE 69 bus distribution system with different tie-switches for optimal reconfiguration. The proposed work has been carried out with MATLAB/MatPower tool and the obtained results are compared and verified using proposed methodology with other existing work. After analyzing the obtained result we can conclude that the optimal reconfiguration with proposed multi-objective function using Particle Swarm Optimization Technique is an efficient approach.
