AEP unified power flow controller performance

IEEE Transactions on Power Delivery, 1999
The installation of the world's first unified power flow controller (UPFC) has been completed and a series of commissioning tests were conducted at the Inez Substation of American Electric Power (AEP) in eastern Kentucky. The project is a collaborative effort between AEP, the Westinghouse Electric Corporation, and the Electric Power Research Institute (

An advanced unified power flow controller

Electrical Engineering, 1996
This paper describes the implementation of a new control approach for the Unified Poer Flow Controller (UPFC), which provides active filtering capabilities to this equipment, besides the functions of power flow control and voltage control, as originally proposed by L. Gyugyi [1,2].

Z-sourced unified power flow controller

6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012), 2012
This paper presents a brief review of Z-source converter. This converter employs a unique impedance network to couple the converter main circuit to the power source thereby overcoming the limitations of the traditional converters and provides a novel power conversion concept.

Optimal power flow control in open power market using unified power flow controller

2001 Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.01CH37262), 2001
Optimal power flow control in open power market using unified power flow controller (UPFC) has been developed in this paper, with static point of view, for congestion management. Installation of UPFC requires a two-step approach. First, the proper location of these devices in the network must be ascertained and then, the settings of its control ...

Power flow control and loss minimization with unified power flow controller (UPFC)

Canadian Conference on Electrical and Computer Engineering 2004 (IEEE Cat. No.04CH37513), 2004
In 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 ...

Genetic algorithms-based power flow control with unified power flow controller

3rd International Conference on Advances in Power System Control, Operation and Management (APSCOM 95), 1995
This paper uses a genetic algorithm (GA) to solve optimal power flow control problems with a unified power flow controller (UPFC). UPFC is used as a continuous phase shifter to regulate both angle and magnitude of branch voltage. The GA, coupled with P-Q power flow, selects the best regulation to minimize the real power loss and keep the power flows in

Power system damping using fuzzy controlled unified power flow controller

2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002
The paper presents a design of a UPFC damping controller using two fuzzy logic schemes one based on Mamdani inference engine using the center of gravity method to find the controller output, and the second based on Takagi-Sugeno engine computing the controller output as linear combination of the inputs.

Unified power flow controller (UPFC) under nonlinear control

Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003
The 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 ...

Control structures for the unified power flow controller

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
The 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.
