Network Reconfiguration for Loss Minimization by Using Johnson's Algorithm

Abstract

Power distributed to the consumers faces many disturbances in the path of the distribution network which leads to severe consequences such as unregulated voltage and real power loss. This problem can be solved effectively by using a technique called network reconfiguration. It is useful to reduce the real power loss and to keep the voltage magnitude within the limits. The proposed work is presented by using Johnson's algorithm which is used to calculate the total minimum impedance to reach the destination feeder. The main purpose of the proposed work is to obtain the shortest path, so that the real power loss can be minimized and voltage regulation can be improvement. Therefore, the proposed algorithm for reconfiguring the network is investigated on IEEE test systems 33 and 118 radial distribution system and their performance is tested with distribution load flow analysis for comparing the real and reactive power loss before and after network reconfiguration.
