Optimal Placement Of Svc Using Fuzzy And Pso Algorithm

In any power system network, voltage stability is a major concern for secure operations. But recently due to their stressed operations for increasing loading, voltage instability and voltage collapse are evitable, which is a major threat to power system. So it is very important to maintain voltage profile within the limits for overloading conditions also, which can possible through optimal placement of Static Var Compensator (SVC). A new approach is proposed in this paper, which is a combination of Fuzzy and Particle Swarm Optimization (PSO). For Optimal locations Fuzzy approach is used. The rating value of SVC is approximated through PSO for different loading conditions. In this paper 125%, 150% and 175% overloading cases are considered. It is observed from the results that the voltage profile of the power system are increased and are within limits, also real power losses are reduced there by optimally locating SVC device in the power system. The proposed method is tested on IEEE 14 bus, IEEE 30 bus system.
