Damodar Reddy Journal on Power Systems Engineering 2322–0376 4 3 39 43 Conductors, Losses, Grey Wolf Optimization, MATLAB Conductor selection plays an important role in distribution system. The usual approach is to select the conductor with the least cost. This has an adverse effect on the losses. There is a need to determine the conductors in such a way that there is reduction in the cost of conductor and reduction in losses. Initially, the type of conductors are selected based on flat voltage profile. To reduce the cost of losses incurred on energy and cost of depreciation and interest, the optimization method named as Grey Wolf Optimization (GWO) is proposed. Also the increase in load which can be applied to the network without changing the configuration of the conductors obtained after optimization is determined. The systems used to test the given objective are 16 bus, 22 bus, and 24 bus systems with MATLAB. August - October 2016 Copyright © 2016 i-manager publications.
