Abstract :
To maintain synchronism with grid in power system for quality power delivered to consumer purpose. Due to this stability problem arises which affects the power flow and transmission efficiency on the transmission line. A rapid growth of power electronics area which introduces the FACTS devices that is able to solve the instabilities problem easily. The Unified Power Flow Controller (UPFC) is a latest generation of FACTS device which can control the parameters of line impedance, terminal voltages, voltage angles and then damping of electromechanical oscillations between interconnected systems for secure operation and also improve system stability. This paper focuses on the UPFC with conventional POD controller and UPFC with PI controller are placed between two machine system inorder to support voltage and damp the oscillation using MATLAB.
