Abstract
The ability to control power flows in electric power systems is one of the crucial factors affecting the overall development of modern power systems. Among FACTS devices, the Unified Power Flow Controller (UPFC) is one the most efficient controller, offering a unique combination of shunt and series fast compensation. This device can be used to control both the active and reactive power of a transmission line. In this paper, a new methodology for incorporating the UPFC in a classical power system transient stability model is proposed. Due to UPFC model simplicity, the study of the dynamic behavior of a power system with embedded power electronics is made easier. A case-study is presented in order to show the effectiveness of the proposed approach. As a by-product, the contribution to enhance power system operation provided by UPFC devices is highlighted.
