Single Stage Integration of PMSG to the Grid Using MMCC-TSBC for WECS

This paper proposes single stage integration of PMSG to the grid through a modular multilevel cascaded converter(MMCC) based on triple star bridge cells (TSBC). It is a direct three-phase AC to AC conversion system. It has capability to allow power flow in both directions(bidirectional). The paper also talks about control methodologies to allow suitable operation of the TSBC. It can find its applications in medium-voltage/high-voltage systems. The validity and effectiveness of the control mechanisms has been verified in this paper using MATLAB based software simulation.
