In this paper optimum size and location of the capacitors and distributed generators (DGs) are determined for power loss reduction using Genetic Algorithm (GA). The main innovation of this paper is using both DG and Capacitor for the power loss reduction. The objective function includes power losses reduction and voltage profile improvement using GA. Allocating the capacitors and DGs should be carefully determined with the consideration of different planning incentives. It shows the importance of installing the exact amount of capacitors and of DGs in the best suitable location. Studies also show that if the capacitors and of DGs are connected at non-optimal locations or have non-optimal sizes, the system losses will be increased. The proposed method is tested for Mazandaran network (16-bus) system, by connecting suitable size of DG, capacitor, and DG and capacitor simultaneously at the optimal location of the system. The results show a considerable reduction in the total power loss in the system and improved voltage profiles of all the buses.
