Unified Power Flow Controller (UPFC)
A Unified Power Flow Controller (UPFC) is a device used in electrical power systems to manage and optimize the flow of electricity. It combines two technologies—shunt and series devices—to control voltage, power flow, and stability in the transmission network. By adjusting these parameters, the UPFC can improve the efficiency of power delivery, reduce losses, and enhance system reliability. Essentially, it acts like a smart regulator, ensuring electricity moves smoothly and securely from generators to end users, even when demand or network conditions change.
