Dynamic modeling of UPFC based on indirect matrix converter

Abstract

One of the most effective Flexible AC Transmission Systems (FACTS) that was used in power system, is the unified power flow controller (UPFC). In this paper, the modeling of a new structure of UPFC based on indirect matrix converter (UPFC-IMC) that is controlled by space vector modulation (SVM), is developed to consider of dynamic studies of power system. Through the presented modeling, the transient and steady states responses of UPFC-IMC are well investigated. The results of the investigation are presented for the transient and steady states by simulating the proposed system in MATLAB changing each system parameter.
