Optimal placement of DG in distribution system using genetic algorithm

Abstract

Power loss minimization is one of the important aspects in the distribution system..This paper deals with power loss minimization by the placement of distributed generators (DG) in the distribution system. The optimal location and sizing of DG for minimization of the power loss and cost of DG is found using GA. These two objectives power loss and cost are conflicting in nature. Moreover in such case only one compromised solution satisfying both objectives is obtained according to the choice of the decision maker. The Multi objective optimization algorithm (NSGA-II) is used to solve these two objectives to get a set of pareto optimal solutions. The simulation study is carried out on a 33 bus Distribution System for different load models. © 2013 Springer International Publishing.
