An Enhanced Swarm Optimization Algorithm for Network Reconfiguration

Power distribution networks are mostly operated in a radial configuration. The dynamics of distribution system operation often requires reconfiguration of the network. Distribution network reconfiguration is achieved by using sectionalizing switches that remain normally closed and tie switches that remain normally open. The main purpose of reconfiguration is to minimize active power losses in order to improve distribution system performance. Particle Swarm optimization to find the best switching pattern which leads to minimum load confined to all equality and inequality constrains allied to distribution system. The objective of the optimization is minimizing active power loss and to improve voltage profile while the distribution network is maintained in the radial structure. In this paper, reconfiguration of IEEE-33 Bus distribution system is done using PSO and results obtained are compared with existing algorithms. The outcome attained illustrates the improvement in voltage profile of each bus and reduction in loss profile as compared with existing algorithms.
