A Weighted Multi-objective Index Based Optimal Distributed Generation Planning in Distribution System

Distributed Generation (DG) sources have been popular due to their potential solution for some issues, like the deregulation in power system and improving the performance of Distribution System. The optimal placement of DG is needed for maximizing the DG benefits in power system such as improving reliability and stability. There are several similar works have been done to find the optimal DG site by their imposed constraints and objectives. In this paper, the siting and sizing of Distributed Generators (DG) in distribution networks are determined using multi-objective indices. The objective is to minimize the real power loss and to improve the voltage profile of the system. To minimize power losses, it is important to find the location and size of local generators to be located in power distribution systems. Best location of the DG is determined by using multi-objective voltage index analysis and size of DG is computed by finding its optimal power factor using Fast Approach. This paper presents the results of simulations for standard Civanlar16-bus and 12 bus Practical Distribution systems.
