Flexible AC transmission system is an evolving technology-based solution to help electric utilities fully utilize their transmission assets. The idea behind the FACTS concept is to enable the transmission system to be an active element in increasing the flexibility of power transfer requirements and in securing stability of integrated power system. FACTS devices improve the existing power system's efficiency and reliability thus enabling us to meet power system load and performance requirements without the need to install new transmission lines or generation utilities. Among the FACTS devices the UPFC is the most versatile and effective device. The UPFC consists of two voltage source converters connected back to back through a DC capacitor. The UPFC is used for real-time control and dynamic compensation of ac transmission systems, providing multifunctional flexibility required to solve many of the problems facing the power industry. The UPFC is able to control, simultaneously or selectively, all the parameters affecting power flow in electric transmission. Alternatively, it can independently control both the real and reactive power flow in the line unlike all other controllers.
