Abstract

UPFC is the best featured device among FACTS devices for different applications in power systems. The main problem with UPFC is the voltage across the dc link varies according to the variation of parameters in the transmission line. This paper proposes a new model of UPFC integrated with a DC source instead of dc link capacitor. Hysterisis current control methods is used for switching the voltage source converters. Model is simulated in SIMULINK MATLAB platform to show the effectiveness of result. The results show that UPFC integrated with the voltage source can reduce the oscillations and transients. Proposed model can control the real and reactive power flow to the power system.
