increasing demand of electrical power for different types of load is degrading the quality of power in the system. So, to improve the power quality, different Flexible AC transmission system (FACTS) devices are used to maintain controllability and capability of electrical power system FACTS controller includes unified power flow controller (UPFC), Static synchronous compensators(STATCOMs), Thyristor controlled series compensators (TCSC), Static series synchronous compensators (SSSCs) and Static VAR compensators (SVCs), are able to improve the real and reactive power flow control through a transmission line at a particular bus in a power system. The (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. It is used to control the flow of power over the transmission line by controlling the impedance, voltage magnitude and phase angle. In this paper we see the performance of UPFC and how it increases the transmission capacity in the transmission line. This paper presents the results of computer simulation and MATLAB program is used to model UPFC and to verify the performance of UPFC under different system conditions.
