An Effective Hybridized GWO-BSA for Resolving Optimal Power Flow Problem with the Inclusion of UPFC

The key intention of this research paper is to find a solution to the optimal power flow problem for four different scenarios such as minimization of fuel cost, minimization of voltage deviation at the buses, minimization of real power loss and enhancing the voltage stability of the system. An effective hybridized Grey Wolf Optimization (GWO) and Backtracking Search optimization Algorithm (BSA) is introduced in this paper to resolve the optimal power flow problem with incorporation of Unified Power Flow Controller (UPFC), a versatile FACTS device. The efficacy of the suggested approach is verified using IEEE 30-bus test system. Finally, results of this hybrid method are compared with the results accessible in literature and found to be superior. Keywords- Optimal power flow; Hybrid GWO-BSA method; FACTS Controller; UPFC.
