Power Loss reduction and Voltage Profile improvement in radial distribution system by implementation of Photovoltaic Generation (PVDG) are the objectives of this study. The multiobjective function based on system performance indices of ILP and ILQ, related to real and reactive power losses, and IVD, related to voltage profile improvement, are utilized in the present work. The Particle Swarm Optimization (PSO) has been employed to minimize the multiobjective function. Two scenarios have been studded in this work. In the first scenario, the constraint for PVDG unit size has not been considered. In the second scenario, the constraint for PVDG unit size has been considered and in both scenario problem has been solved with one PVDG. The studies have been carried out on IEEE 33 bus test. The results show that PVDG penetration has decreased power loss and improved voltage profile. Comparison of the results obtained by the proposed method with those attained in other studies shows the effectiveness of the proposed method.
