Abstract: Nowadays, the demand for electricity generation is increased tremendously as the utilization of it and other distributed power systems have expanded drastically. With respect to demand of power, at times, it is not possible as well as economical to set up new /transmission lines. The increment in the non-linear loads and the consumption of electrical energy in power systems tend to force the electrical power utilities to provide a large electrical power and this is the cause that this problem becoming more and more significance in power systems. Hence in Electrical Power System for governing, UPFC is the most promising FACTS controller. UPFC is the versatile facts device which can provide full dynamic control of transmission line parameter, bus voltage, line impedance as well as angle, for improvement of system stability and security. In this paper, Unified Power Flow Controller is studied to improve the power flow over a transmission line in a standard IEEE 14 bus system by using MATLAB / SIMULINK. For the selected system, active and reactive power flows are compared with and without UPFC.
