Abstract—The unified power flow controller (UPFC) is a pair of back to back power electronic inverters which controls the real and reactive power flow in a transmission line. This paper describes the modeling and simulation of IEEE 30 bus system employing UPFC. Simulink models are developed for IEEE 30 bus system with and without UPFC. Digital simulation using MATLAB/SIMULINK is done with these models and the results are presented. The effect of UPFC on real power, reactive power and the voltage is also presented.
