— In this paper, a methodology techniques used for the radial distribution system for determining size of the conductor, location and number of capacitors to be placed in the system and also selection of optimal conductors. The main Objective of this paper is for two purposes. One is to minimize the real and reactive power losses in the system and to maximize the total saving in cost of conducting material while maintaining the acceptable voltage levels in order to better quality supply to consumers. In this paper, an Index Vector based Algorithm for determining the suitable candidate nodes, for capacitor allocation in the radial distribution systems is presented. This method also gives the size and the number of capacitors to be placed in the system. As capacitor placement problem is a non-linear optimization problem, Genetic Algorithm technique is used to determine the rating of the capacitors. Further, Genetic Algorithm is proposed for selecting the optimum size of conductors, of feeder segment of radial distribution networks to meet the increasing demands more reliably and economically. The effectiveness of the proposed method has been tested on Agricultural feeders of Andhra Pradesh Northern Power Distribution Company Limited (APNPDCL).
