[email protected] Abstract This paper describes the theory and simulation
by mat lab of flexible Alternative Current Transmission Systems (FACTS) devices
used in the disturbed power systems. One of these devices, Unified Power Flow
Controller (UPFC) will be chosen for a specific application, detailed in this paper.
Simulation investigate the effect of UPFC on the voltage of the related bus, it s also
considers the effect on the amount active and reactive power flowing through the
transmission system. Finally simulation results have been presented to indicate the
improvement in the performance of the UPFC to control voltage in disturbed power
systems. Index Terms Facts, UPFC, Power Systems, disturbances, Interface,
Modeling, Controls. I.INTRODUCTION The term FACTS (Flexible AC
Transmission Systems) covers several power electronics based systems used for AC
power transmission and distribution. The most interesting for transmission
