An Analytical Approach for Optimal Siting and Sizing of Distributed Generation in Radial Distribution Systems

Prem Prakash, Dheeraj K. Khatod

Abstract


In this study, an analytical approach based technique is presented for optimal sizing and siting of distributed generation (DG) units in balanced radial distribution system. The formulations of developed technique are based on reducing the active and reactive components of system loss related to branch currents. In the proposed technique the magnitude of branch current is reduced by installation of DG units at various positions in distribution system. According to present technique, it identifies a group of buses where DGs are to be placed. Further, the loss saving formulations is used for obtaining optimum size of DG units by classical optimization technique. An algorithm is also developed to optimum placement of DG in distribution system. The developed method is relatively simple it needs the solution of base case load flow only. The developed technique has been checked on a 15-bus radial test distribution network. The developed analytical method is very much effective to reduce the system losses as it can be seen from results.

Keywords: analytical technique, distribution system, loss reduction, optimal sizing and siting
