Increasing load demand in distribution system, needs extension of distribution system or restructure of network. All the changes in the distribution network, to respond load demand increasing, known as development of distribution system. Due to the development of distribution systems and increasing electricity demand, and in order to overcome the shortcomings of distribution systems such as high loss and low loadability, the use of distributed generation (DG) and FACTS devices such as DSTATCOMs are increasing. The placement of these devices is a significant factor affecting network loss reduction and improving network performance. In this paper, in order to achieve optimal places of DGs and DSTATCOMs, a new objective function is proposed and optimized based on the genetic algorithm (GA). The objective function includes system loadability and network loss. The proposed method is applied to the IEEE 33-bus and 69-bus test system and optimal places of DGs and DSTATCOMs are achieved by the proposed method. The results show the effectiveness of the proposed method to loadability improvement and loss reduction. As metaheuristic algorithms cannot exactly find optimal point in some problems, the results of this paper are near-optimal points for places of DGs and DSTATCOMs.
