What is the Function of Unified Power Flow Controller?

In a number of cases, it may be possible to increase the grid’s capacity through enhanced control of the active and reactive power flow in the transmission network independently of busbar voltage. The Unified Power Flow Controller (UPFC) provides the reactive shunt compensation, active and reactive series compensation and phase shifting. It is thus capable of regulating the magnitude and phase angle of sending and receiving end voltages, hence controlling power flow in the transmission line and selectively changing transmission line impedance.
