This paper explores the use of a Unified Power Flow Controller (UPFC) for global power system control. Coordinated control schemes are assigned to the UPFC, Power System Stabilizer (PSS) and generator excitation to maintain transient stability and voltage stability following a disturbance. The extension to use of UPFC in damping inter-area oscillation is also considered. Under the proposed coor...

Among stability issues, the damping of electromechanical oscillations has been recognized as an important issue in electrical power system operation. This paper investigates the ability of Genetic Algorithm (GA) to design power system stabilizer (PSS) to damp the inter area oscillation. For this the parameter of the PSS are determined by GA using a phased-based objective function. The numerical...

Unified Power Flow Controller (UPFC) is a power electronic based device that has capability of controlling the power flow through the line by controlling appropriate its series and shunt parameter. It has been reported that UPFC can improve transient stability of a simple system. This paper investigates the improvement of transient stability of inter-area power system. The mathematical model of...
