The Unified Power Flow Controller (UPFC) is used to control the flow of power in the transmission systems by controlling the impedance, voltage magnitude and phase angle. 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 controller offers advantages in terms of static and dynamic operation of the power system. It also brings in new challenges in power electronics and power system design. FACTS devices are mostly used to control the flow of power, to increase the transmission capacity and to optimize the power system stability. The most widely used FACTS device is Unified Power Flow Controller (UPFC). The controller used in the considered system has a significantly effects on improving the real power and compensating the reactive power. In this paper, the capability of UPFC is observed for the transmission line based on PI and fuzzy logic controllers (FLC).
