An alternative control strategy of a UPFC, based on hysteresis control of the switches is presented. It is shown that a UPFC under hysteresis control will have nearly sinusoidal injected output current and voltage for reactive power and real power compensation while keeping the UPFC in its simplest configuration.

UPFC Modeling in the Harmonic Domain
IEEE Transactions on Power Delivery, 2006This paper outlines the extension of harmonic domain modeling to flexible ac transmission system (FACTS) devices which contain series voltage injection elements. The proposed iterative technique is capable of modeling generic combinations of series and shunt converters; representing these elements as harmonic current and voltage sources, respectively ...

2007 IEEE Power Engineering Society General Meeting, 2007
Summary form only given. This paper presents a screening technique for greatly reducing the computation involved in determining the optimal location of a unified power flow controller (UPFC) in a power system. The first-order sensitivities of the generation cost with respect to UPFC control parameters are derived.

Multi-teriminal UPFC for power system deregulation
2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002One original purpose of FACTS controllers is to increase the transmission capacity of existing lines thus deferring the necessity of building new lines. FACTS, such as the unified power flow controller (UPFC), have also been regarded as controllers for routing power in the market-driven, deregulated power systems.

Dynamic decoupled compensator for UPFC control
Proceedings. International Conference on Power System Technology, 2003It has been reported that there is a strong dynamic interaction between the active and reactive power flow through a transmission line when they are controlled by a unified power flow controller. This paper proposes a dynamic decoupled (DD) compensator, used in conjunction with a proportional-integral (PI) controller, to eliminate the dynamic ...

Optimal parameters of UPFC for power flow
2006 India International Conference on Power Electronics, 2006Unified power flow controller (UPFC) is a versatile flexible AC transmission system (FACTS) controller which can be used for voltage and power flow control. In some situations such as transient stability control, it is required to maximize and minimize the power flow on certain transmission lines.
