Power loss minimization by the placement of DG in distribution system using GA

Abstract

Power loss minimization is an important aspect of distribution System where the load variation is more compared to other systems. There are different methods to minimize the power loss like DG placement, capacitor placement, load balancing etc. Among those methods DG placement was much more beneficial because it is directly related to real power loss. This paper is based on power loss minimization by the placement of distributed generators (DG) in the distribution system. The location of DG is found with the help of voltage stability index (VSI) and DG size is varied in small steps and corresponding power loss is calculated by running the power flow and the result obtained is verified by Genetic Algorithm. The simulation study is carried out on a 33 bus Distribution System by considering different load models. © 2012 Springer-Verlag.
