Effective Loss Minimization in Main Distribution System by Assignment of Numerous Distributed Generators

This paper clarifies an effective improved methodology for numerous distributed generator-DG placement in main distribution system for loss reduction. Optimal location for distributed generator-DG is placed by Improved Analytical expressions and the optimal DG size calculated by Improved Analytical-IA method and loss sensitivity factor-LSF method. The effective method is totally based on IA expressions to formulate the optimal size of 4-types of different DG types and a methodology to select the best Placement for DG allocation. A technique to get the optimal power factor is submitted for DG capable of presenting real and reactive power these two methods are tested on two bus systems 33-bus and 69-bus radial distribution systems. The output reliability of the DG is economical or non economical on the system will relays on the placement and size of the DG. DG has become most popular as it is seen to be the reliable option for solving bigger problem in energy industry which has attained the following goals like reduction of huge loss, decrease line losses, improving voltage profile at feeders and environmental effect are the overall advantages. The MATLAB simulation results gained gives the performance of the IA method over the LSF method.
