Power Flow Control by Unified Power Flow Controller [PDF]
Engineering, Technology & Applied Science Research, 2019 The demand for electricity is increasing day by day and we have to produce more electrical energy to meet the load demands. Most of the experts prefer to extend the existing electrical networks over building the new network with greater costs. In this paper, the implementation of the flexible AC transmission systems (FACTS) devices in a simple ...

Control design and simulation of unified power flow controller [PDF]
IEEE Transactions on Power Delivery, 1998 The unified power flow controller (UPFC) is a solid-state controller which can be used to control active and reactive power flows in a power transmission line. In this paper, the authors propose a control strategy for UPFC in which they control real power flow through the line, while regulating magnitudes of the voltages at its two ports. They design a

Control and analysis of a unified power flow controller [PDF]
IEEE Transactions on Power Electronics, 1999 This paper presents a control scheme and comprehensive analysis for a unified power flow controller (UPFC) on the basis of theory, computer simulation and experiment. This developed theoretical analysis reveals that a conventional power feedback control scheme makes the UPFC induce power fluctuation in transient states.
