Determination of simultaneously contributions of several distributed generation for reduction of losses

So far a variety of methods were applied to optimized placement of distributed generation which we can refer to casual-based algorithms such as PSO, analytical method and load flow method. In this paper, we have used an analytical method based on minimizing loss and generalized it for simultaneous placement of two DGs in two sample networks and we have found the best places and capacities for installation of DGs. To evaluate the results, consideration method for all modes is applied in this network. Moreover, the results were compared with those obtained by PSO method. 33 and 69 buses systems were studied too. The findings show that the proposed method is more accurate than PSO method, and its convergence speed is better than that of consideration method for all possible modes
