Dual voltage source inverter (DVSI) scheme to enhance the power quality and reliability of the microgrid system

Abstract

The thesis focuses on a Dual-commutated voltage source Inverter (DVSI) connected to a grid in a wind energy application. The proposed scheme is involved two inverters, which empowers the micro grid to trade power created by the distributed energy resources (DERs) furthermore to compensate the nearby unbalanced and nonlinear burden. The control calculations are produced taking into account instantaneous symmetrical component theory (ISCT) to work DVSI in grid sharing and grid infusing modes. The proposed plan has expanded unwavering quality, lower data transfer capacity necessity of the primary inverter, lower taken a toll because of diminishment in channel size, and better use of micro grid power while utilizing lessened dc-link voltage rating for the fundamental inverter.
