Abstract

In order to improve the Voltage Stability Index (VSI), real and reactive power loss compensation, there is a solution in terms of Distributed Generation (DG). By incorporating DGs at proper location with suitable size the power losses will be reduced and there is an improvement of voltage profile. For this a new approach was introduced which is a hybridization of Firefly Algorithm (FA) with Gravitational Search Algorithms (GSA). After finding the real power losses using conventional method like Backward/Forward (BW/FW) sweep approach, the new approach was implemented to prove that it was the better algorithm than the other approaches. All these approaches have been implemented on standard IEEE-33 radial test system. MATLAB software was used to simulate the results and to find optimal DG sizing and siting on IEEE-33 test system.
