Modulation and Control of Transformerless UPFC

IEEE Transactions on Power Electronics, 2016
In this paper, a modulation and control method for the new transformerless unified power flow controller (UPFC) is presented. As is well known, the conventional UPFC that consists of two back-to-back inverters requires bulky and often complicated zigzag transformers for isolation and reaching high power rating with desired voltage waveforms.

Control system for a UPFC in a transmission line

IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2000
This paper focuses on the control of the power flow through a transmission line using a PWM.based UPFC. The dynamic model of the UPFC has been developed using the space-vector representarion of the instantaneous three-phase variables. The Park’s transformation and the reference frame selected reduce the control of the real- and reactive-power ...

Dynamic security corrective control by UPFCs

IEEE Transactions on Power Systems, 2001
This paper deals with the development of a nonlinear programming methodology for evaluating corrective actions to improve the dynamic security of power systems when transient instability is detected. Remedial actions are implemented by exploiting the fast response of unified power flow controllers (UPFCs). The algorithm is implemented and tested on the
