A hybrid algorithm for optimal allocation of DG in radial distribution system

Due to the incremental demands for electrical energy, Distributed Generator (DG) sources are prominent in distribution systems. At the same time, the Locations and Capacities of DG sources have profoundly influenced the system losses in a distribution network. In this paper, a Hybrid algorithm using Power Loss Index (PLI) & Genetic Algorithm (GA) presented for optimized Location and sizing of DG with the objectives of minimizing network power losses, improving voltage regulation and good voltage stability within the framework of system operation and security constraints on 15 Bus and 33 Bus radial distribution systems(RDS). The performance analysis has made by comparing all objectives of all systems with and without DG Installation. To this end, a comparison of real power loss and voltage profile has been made between PLI-GA and GA approaches.
