A Novel Method for Optimal Distributed Generator Placement in Radial Distribution Systems

Abstract

Optimal placement of distributed generators is essential, as inappropriate placement may increase the system losses. This article proposes a novel methodology for finding the optimal size and location for installation of Distributed Generators (DGs) so as to minimize total power losses in radial distribution systems. Distribution load flow is used to find the power loss in the system. The Proposed methodology is tested with 69-node radial distribution system with single and multiple DGs and the efficacy is compared with the Acharya's method and classical grid search algorithm. Effect of optimal DGs placement on system voltage profile and branch power losses are also computed and reported
