Allocating Loss with Network Reconfiguration in Radial Distribution Networks

In this paper, loss is allocated to the various nodes in a radial distribution network when the network undergoes reconfiguration to reduce the overall power loss. A new method of loss allocation is formulated using the bus identification scheme described. Network reconfiguration is performed using branch exchange based heuristic method where the bus identification scheme changes dynamically with changing topology of the network for obtaining a minimum power loss configuration. Loss allocation is then performed for the reconfigured network and the original network. The loss allocation results of a 69-bus radial distribution system are analysed and compared.
