Abstract—Unified Power Flow Controller (UPFC) is the most effective FACTS device. UPFC is able to control the real and reactive power along with voltage magnitude and phase angle. When we talk about the interconnected network, the main concern is maximum use of the transfer capacity of interconnected line. Within the line limits conditions, UPFC is capable to maximize the power transfer capacity between the two interconnected power systems. This paper proposes use of phasor model of UPFC to maximize the power transfer capacity of interconnected power systems. UPFC is installed at the interconnecting line. The modeling is done in Matlab/Simulink using test system consisting of 20 bus system incorporating UPFC. The simulation results clearly show that the model using UPFC has maximum value of power transfer as compared to the model without UPFC.
