Power Flow Control through Transmission Line with UPFC to Mitigate Contingency

This paper is based on practical contingency condition of a transmission line, over which a study using UPFC is done without sacrificing the available generation capacity. The Unified Power Flow Controller (UPFC) is the most versatile and complex power electronic equipment that has emerged for the control and optimization of power flow in electrical power transmission system. Installing the UPFC makes it possible to control an amount of real power flow through the line. This paper presents control of power flow through overloaded/under loaded line under study. Simulation were carried out using MATLAB software to overcome the contingency condition by using UPFC .
