Optimum Power Flow and Optimum Placement of Unified Power Flow Controller (UPFC) using Optimization Techniques

This paper presents the Optimum Power Flow (OPF) and Optimum placement of UPFC using optimization techniques, Particle Swarm Optimization (PSO) and Cuckoo Search (CS) Algorithm. The IEEE 30 bus system is used as a test system and performance of PSO and CS algorithm evaluated with and without UPFC on test system. The optimum placement of UPFC is carried out using OPF. Further it is seen that by using CS algorithm transmission loss, generation cost are minimized compared to PSO algorithm. The optimum placement of UPFC improves the voltage profile of test bus system.
