Multiterminal unified power flow controller

IEEE Transactions on Power Electronics, 2000
This paper describes a multiterminal unified power flow controller (M-UPFC) for the management of real and reactive powers of several transmission lines emanating from a single bus. The example of the paper consists of the bus of a generator station. The M-UPFC is based on synthesizing several of L. Gyugyi's UPFCs so that they share a single pair of DC

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 ...

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), 2002
The 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, 2015
Flexible 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), 2003
The 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).
