Literature Survey on Loss Reduction Methods for Three Phase Unbalanced Radial Distribution Network

Abstract

The large network of power system ends at distribution system, where voltage is low and current is high. For primary distribution, three phase ac line parameters are considered. Mutual coupling and unbalanced loading makes unsymmetrical current flow and irregular voltage drop in the network, consequently branch losses are different in each phase. This paper has brief description about loss minimization approaches like Distributed generator (DG), capacitor placement and feeder reconfiguration for unbalanced radial distribution network.
