Investigation of advanced control for unified power flow controller (UPFC) to improve the performance of power system

Journal of Applied and Emerging Sciences, 2021
Recently, global power demand has significantly increased. As this demand does not have proportional impact with transmission capacity and power generation. The new techniques are used to improve power system performance. The Flexible Alternating Current Transmission System (FACTS) devices are applied to improve the existing transmission network ...

Optimal robust stabilizer design based on UPFC for interconnected power systems considering time delay

Archives of Electrical Engineering, 2017
A robust auxiliary wide area damping controller is proposed for a unified power flow controller (UPFC). The mixed H2 / H∞ problem with regional pole placement, resolved by linear matrix inequality (LMI), is applied for controller design.

INJECTION POWER UPFC MODEL FOR INCORPORATION OF UNIFIED POWER FLOW CONTROLLER IN LOAD FLOW STUDIES [PDF]

JES. Journal of Engineering Sciences, 2007
This paper is devoted to the incorporation of the s teady-state model of the unified power flow controller (UPFC) in power flow programs using a UPFC injection model. The adopted UPFC injection mo del is based on the representation of UPFC in steady-state conditio ns by two voltage sources in series with certain reactances.
