Unified Power Flow Controllers for Security-Constrained Transmission Management
IEEE Transactions on Power Systems, 2004Although flexible ac transmission system (FACTS) devices and unified power flow controllers (UPFCs) have proven to be powerful tools for the exploitation of network capacities, their performances with regard to transient stability have not been deeply explored yet.

Dynamic control of a unified power flow controller
PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002The performance of a unified power flow controller (UPFC) with four different controllers is evaluated through simulation and implementation in an experimental laboratory model. The controllers which were investigated are the PI controller, PI controller with decoupling, cross-coupling controller and robust H/spl infin/ controller. It is found that the

Versatile control strategy of the unified power flow controller (UPFC)
2000 Canadian Conference on Electrical and Computer Engineering. Conference Proceedings. Navigating to a New Era (Cat. No.00TH8492), 2002The unified power flow controller (UPFC) is a third generation flexible AC transmission system (FACTS) that uses solid state electronics to control the flow of power through lines in a faster and more economical fashion. In this paper, we propose a versatile control strategy of the UPFC that joins shunt active filtering and system balancing ...

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 ...

Damping function of unified power flow controller
IEE Proceedings - Generation, Transmission and Distribution, 1999The paper presents the establishment of a linearised Phillips-Heffron model of a power system installed with a unified power flow controller (UPFC). On the basis of the linearised model, the damping function of the UPFC is investigated. Basic issues on the design of the UPFC damping controller are discussed, regarding the effectiveness and robustness ...
