Power flow control capability analysis of unified power flow controller

i-manager's Journal on Power Systems Engineering, 2022
In the field of power system restructuring, Flexible Alternating Current Transmission System (FACTS) technology has become indispensable for alleviating the challenges of load flow control, voltage control, transient stability, and dynamic stability. The Unified Power Flow Controller (UPFC) is the fastest, most flexible, and most capable FACTS device ...

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.

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 ...

Multi-terminal unified power flow controller

PESC 98 Record. 29th Annual IEEE Power Electronics Specialists Conference (Cat. No.98CH36196), 2002
This paper describes a multi-terminal unified power flow controller (UPFC) for the management of the 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 multi-terminal UPFC (M-UPFC) is based on synthesizing several of L.

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 ...
