Nowadays, increasing the numbers of DG units has affected the system parameters like stability and power losses. Controlling these parameters makes the power system operators optimize the placement and penetration level of these sources. Consequently, several methods with various targets have been studied until now. In this paper, the evaluation of placement and penetration level of DG units considering stability improvement and power losses reduction has been investigated. To achieve these goals, different objective functions with several operating constraints were proposed. The well-known NSGA_II was utilized to optimize the objective functions considering the operating constraints. NSGA_II is an evolutionary based multi-objective optimization tools which has great advantages in comparison with other evolutionary algorithms. The utilized method was applied to IEEE 14-bus and 57-bus test systems. The ability of the proposed method in enhancing of voltage stability, improvement of voltage profile, and reduction of power losses were confirmed using simulation results.
