Optimal Sizing and Sitting of Distributed Generator to Improve Efficiency of Distribution System: A Comparative Analysis

Abstract

Improvement in efficiency of distribution system by the placement of small-size generators (distributed generators), where the locations and ratings of DGs are obtained by any optimization algorithm, is now a major challenge for researches. This article presents an overview of different approaches (conventional, analytical and heuristic) for proper placement and sizing of distributed generators in distribution network. In this article, heuristic approach is applied to optimize the DG’s placement and results are compared with classical and analytical approaches. Comparative results are presented to show the effectiveness of the methodologies.
