In the current scenario of power system transmission, the demand for more optimal and profitable operation is very essential. One of the major concerns in utilizing electric power is to maintain steady voltage in the system. Improved utilization of existing power system can be achieved through the application of FACTS devices which improves the transmission quality and efficiency of power transmission by supplying inductive or reactive power to the grid. In this paper, an IEEE 5 bus system is considered for detailed analysis and load flow studies is done using Newton Raphson method. The algorithm named Particle Swarm optimization (PSO) is used to detect the best position and minimum rating for SVC to maintain voltage within the stipulated limits. Modelling of SVC is done using MATLAB software. Fuzzy logic controller (FLC) is used for control of SVC. SVC is placed at optimal location and the voltage stability is verified by varying the loads.
