Optimal Placement And Sizing Of Pvdgs In Radial Distribution System Using Hybrid Pso-gsa
Authors : Zellagui Mohamed .
Abstract
The objectives of this work are to minimize power losses and improve voltage profile in the radial distribution system by the optimal placement and sizing of Photovoltaic Distributed Generators (PVDGs). The hybrid Particle Swarm Optimization-Gravitational Search Algorithm (PSO-GSA) been employed to minimize a multi-objective function. Two scenarios have been studied in this work. In the first scenario, the constraint for PVDG unit size has not been considered and problem has been solved for different number of PVDGs (one, two and three). In the second scenario, the constraint for PVDG unit size has been considered and problem has been solved while using one PVDG. The studies have been carried out on IEEE 33-bus test system. The results show that PVDG penetration has decreased power loss and improved the voltage profile. Comparison of the results obtained by the proposed optimization PSO-GSA with those attained in other studies shows the effectiveness of the proposed method.
