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.

Fuzzy OPF incorporating UPFC

IEE Proceedings - Generation, Transmission and Distribution, 2004
A new optimal reactive power flow (ORPF) method is proposed which considers the inclusion of unified power flow controllers (UPFC). The modelling and inclusion of UPFC in the solution of power flow equations is presented. The ORPF problem is formulated as a fuzzy optimisation problem considering the objectives of minimising system transmission loss and

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

Simulation of UPFC

2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002
This presentation describes the modeling techniques for a voltage source converter (VSC)-based flexible alternating current transmission systems (FACTS) controller, such as a unified power flow controller (UPFC). The model is implemented in an Electro-Magnetic Transients Program (EMTP) simulation package and the results are compared with the ...
