Control structures for the unified power flow controller
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014The basic principles of UPFC operation are discussed and the series inverter dynamics are explained. Two control strategies — the Cross-Coupling method and the Advanced Control method are discussed in detail and their bode plots are analyzed. The two control methods are implemented in PSCAD for the NYPA UPFC at Marcy substation.

Basic control of unified power flow controller
IEEE Transactions on Power Systems, 1997A unified power flow controller (UPFC) is a typical FACTS device capable of instantaneous control of three power system parameters. This paper presents a basic control system which enables the UPFC to follow the changes in reference values of the active and reactive power supplied from the outer system controller.

Investigation of a unified power flow controller
IEE Proceedings - Generation, Transmission and Distribution, 1999Power flow in an AC transmission system depends on three basic parameters: transmission line impedance, voltage magnitude and phase angle. Maximum utilisation of the power system can be ensured by the control of these parameters in real-time. It is shown experimentally that a unified power flow controller (UPFC) can control each of the parameters ...
