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 ...

Experimental verification of deadbeat control for unified power flow controller
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015Flexible AC Transmission System (FACTS) component is available to manage a number of varied situations of the power line. The Unifier Power Flow Controller (UPFC) as one of the FACTS is used in order to keep conditions of the power line. The UPFC consists of two inverters. One is connected in parallel to the power line, the other is connected in series.

Comparison of the 'Sen' transformer with the unified power flow controller
2003 IEEE Power Engineering Society General Meeting (IEEE Cat. No.03CH37491), 2003The independent control of active and reactive power flow in a transmission line is necessary for the transfer of bulk power along a desired path in the most economical way. A "Sen" transformer (ST) uses transformer and tap changers that are traditionally used to build a voltage-regulating transformer (VRT) and a phase angle regulator (PAR).

Optimal power flow control in open power market using unified power flow controller
2001 Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.01CH37262), 2001Optimal 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 ...

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), 1995This 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
