Optimum Placement of UPFC Using Evolutionary Algorithms

Among the different FACTS devices the cost of Unified Power Flow Controller (UPFC) are more expensive, optimum location of these devices plays important role in power system. This paper proposes a multi-objective optimization problem work using Gray Wolf Optimizer- Cuckoo Search (GWO-CS) algorithm for UPFC to place optimally. The cost of generation is used as the objective function, by considering optimum power flow. The results of proposed algorithm are compared with Particle Swarm Optimization (PSO) and Cuckoo Search (CS) algorithms. Comprehensive study includes the proposed algorithms for placement of UPFC, cost of generation & voltage profile of IEEE 62 bus test system.
