Abstract

Accompanying with many flexible AC transmission system(FACTS) devices put into operation, the safety and reliability of power system operation have been suffering more serious influence and unprecedented challenge. Moreover, it's always difficult to comprehensively and accurately analyze the impacts of UPFC, the most versatile FACTS, on the operation characteristics of power system. This paper presents a framework for UPFC modeling based on the user-defined modeling (UDM) theory as well as a leading-edge stability analysis software named DSAToolsTM. Furthermore, the characteristics of steady-state and dynamic responses are compared and analyzed under the condition of two-machine system. Numerical results from various simulations verify the feasibility and effectiveness of the proposed UPFC in terms of both the independent regulation of power flow and the improvement of transient stability.
