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 ...

Power flow control and loss minimization with unified power flow controller (UPFC)
Canadian Conference on Electrical and Computer Engineering 2004 (IEEE Cat. No.04CH37513), 2004In this paper, the UPFC injection model is used to investigate its effect on load flow and loss reduction in power systems. In this study, the Newton-Raphson algorithm is modified to consider the benefits of having a UPFC in the power system. Simulations have been implemented in MATLAB and the IEEE 14-bus system has been used as a case study ...

A new approach for the dynamic control of unified power flow controller (UPFC)
2001 Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.01CH37262), 2001This paper presents a new approach for the dynamic control of FACTS apparatus, such as the UPFC and the STATCOM. With the new control strategy, the capabilities of the UPFC can be exploited not only for steady state power flow control but also to improve damping and transient stability assuring a good behavior during contingencies and the protection of

Unified power flow controller (UPFC) under nonlinear control
Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003The equations of the PWM voltage-source converter (PWM-VSC) are inherently nonlinear. This paper applies the nonlinear control, associated with A. Isidori, to the unified power flow controller (UPFC). Since the UPFC comprises two PWM-VSCs, this paper is one step further in complexity than the previous application of nonlinear control to the static ...

A novel method of power flow analysis with unified power flow controller (UPFC)
2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002This paper presents a novel method for power flow analysis with unified power flow controllers (UPFC). A UPFC power flow model has been proposed, in which the impacts of UPFC devices on the system are modeled as the equivalent loads. According to typical control objectives of UPFCs, several sets of calculation formulas for the equivalent loads are ...
