Research ArticleOpen accessPhrase in the titlePower System Stability Enhancement Using Unified Power Flow ControllerPrechanon KumkratugProblem statement: The enhancement of transient stability of the power system is one of the most challenging research areas in power engineer. Approach: This study presents the method to enhance transient stability of power system by Unified Power Flow Controller (UPFC). The mathematical model of power system equipped with a UPFC is systematically derived. The parameters of UPFC are modeled … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 7,675 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleRobust Decentralized Control of Unified Power Flow ControllerHossein Shayeghi, Ali AbdolalipourA new approach based on structured singular value is proposed for the robust decentralized Unified Power Flow Controller (UPFC) design. To achieve decentralization, using the schauder fixed point theorem the synthesis and analysis of Multi-Input Multi-output (MIMO) control system is translated into set of equivalent Multi-Input Single-Output (MISO) control system. Power systems such as the other industrial plants contain different … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,151 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePower System Oscillations Damping Using Unified Power Flow Controller-Based StabilizerLokman H. Hassan, M. Moghavvemi, Haider A.F. MohamedProblem statement: The Phillips-Heffron model of a power system with UPFC published by AJAS, demonstrates the effect of the UPFC in improving power system oscillation stability. Unfortunately, some of the equations have not been correctly derived and so working with this model in its existing form is misleading. Approach: In this study, the model is revisited and the equations are … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,936 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign of UPFC Controller Using Modified Bilinear Equation for Improving Transient StabilityMajid Nayeripour, Taher NiknamBased on the use of the modified bilinear equation for the unified power flow controller (UPFC), this paper proposes a new control strategy to improve the transient stability of power system. This control strategy is applied to shunt and series inverters of UPFC as the modulating signals at the operating point. This input signals are such that the derivative of … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,638 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign of Robust Decentralized Control for UPFC Controller Based on Structured Singular ValueSeyed Abbas Taher, Shahabeddin Akbari, Ali Abdolalipour, Reza HemattiNew approach based on structured singular value (µ-synthesis) was proposed for the robust decentralized unified power flow controller (UPFC) design. To achieve decentralization, using the Schauder fixed point theorem the synthesis and analysis of multi-input multi-output (MIMO) control system translated into a set of equivalent multi-input single-output (MISO) control system. Power systems similar to other industrial plants contain different kinds … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,032 accessesView PDFCite
