The increasing demand for electrical energy and the necessity to enhance the efficiency and stability of power networks have made the integration of distributed generation (DG) resources in distribution networks a key solution. However, the proper selection of DG resources and their parameters plays a significant role in their effective utilization. In this study, the impact of various types of distributed generation resources, as well as their quantity effect, is examined in a real radial distribution network. For this purpose, the sizing and placement of these resources are conducted using the Particle Swarm Optimization (PSO) algorithm. The analyses focus on two objectives: the optimal location and sizing of DG units in the network and the evaluation of parameters related to power losses and voltage profile. The results indicate that deploying distributed generation units at the proposed locations with the recommended capacities and quantities can significantly reduce energy losses and improve the voltage profile. MATLAB software was used for the simulations in this research.
