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

Basic control of unified power flow controller

IEEE Transactions on Power Systems, 1997
A unified power flow controller (UPFC) is a typical FACTS device capable of instantaneous control of three power system parameters. This paper presents a basic control system which enables the UPFC to follow the changes in reference values of the active and reactive power supplied from the outer system controller.

Simulation Study of Fuzzy Based Unified Power Flow Controller on Power Flow Controlling

2008 Workshop on Power Electronics and Intelligent Transportation System, 2008
Unified power flow controller (UPFC) is the most widely used FACTS device to control the power flow and to optimize the system stability in the transmission line. The controller used in the control mechanism has an important effect on the performance of UPFC.

Locating unified power flow controller for enhancing power system loadability [PDF]

2005 International Conference on Future Power Systems, 2005
In a power system transmission network, there are some corridors which are lightly loaded whereas some of the corridors are critically loaded and thus power system is operating near to critical state. Flexible AC transmission systems (FACTS) plays a vital role in improving the power system performance, both the static and dynamic, and enhanced the ...
