Optimum Position and Optimum Size of the Distributed Generators for Different Bus Network using Genetic Algorithm

The computation of excellent location and the optimum size of Distributed generator (DG) play an important role in electrical power system. It results to reduced power losses and increased voltage profiles. In a real time situation finding the suitable DG position and size is difficult due to various restriction in the distribution system. An advance technique for placement and sizing of DG in electric power system is carried out in this paper. This paper introduces an Optimization technique called Genetic algorithm (GA) for finding an optimum place and size for DG. In recent years the government subsidized programs and improved Distribution network has increased the use of Distributed generator(DG) in commercial and domestic electrical power output. GA fitness function is applied to voltage constraints, active & reactive power losses constraints & DG size constraints. This method is carried out on 14 buses, 30 bus, 57 bus distribution system. The optimization process has been examined using Newton Raphson (N-R) method and by Genetic Algorithm (GA) method for different bus system.
