Congestion Management in Deregulated Power System by Fuzzy Based Optimal Location and Sizing of UPFC
Authors: , ,
Abstract: This paper presents a congestion management methodology in deregulated power systems by optimal location and sizing of Unified Power Flow Controller (UPFC) in a transmission network. A multi-objective optimization problem has been developed by considering total congestion cost, power loss and system severity. A Fuzzy based approach has been proposed to identify the optimal location and sizing of UPFC for relieving congestion in a deregulated power system. The reliability of the proposed work has been analyzed under severe contingencies and line overloading. Simulation results obtained from the Fuzzy method are compared with the solutions obtained by the conventional Sequential Quadratic Programming (SQP) approach. This comparison confirms the effectiveness of the proposed fuzzy method for relieving congestion. The validation of the proposed work is analyzed using IEEE 30-bus system.
