Distributed Generations (DG) Allocation sources are becoming more prominent in distribution systems due to the incremental demands for electrical energy. Determination of optimal location and size of DGs is one of the major problems of distribution utilities. In This paper presents multi-objective function to determine the optimal locations with NSGA II Algorithm to place DGs in distribution system to minimize power loss of the system and enhance reliability improvement and voltage profile. The method has a potential to be a tool for identifying the best location and rating of a DG to be installed for improving voltage profile, line losses reduction and reduce Expected Energy Not Served (EENS) in power system. Moreover, current reduction is obtained in distribution system.
