Optimal control of unified power flow controller (UPFC) to enhance power system transient stability



This paper investigates the feasibility of a unified power flow controller (UPFC) to improve power system transient stability. Based on the developed model, the impact of control strategy, parameters, and location of UPFC on power system transient stability are discussed. The direct method approach is used for this study, because its simplicity enhances understanding of the measures that have been taken to improve stability
