Integration of Silicon Carbide devices to increase the AEP (Annual Energy Production) in a PM based wind generation system

Abstract

A radical energetic change is needed nowadays and enhancing renewable energies should play a main role. For its superior performance and lower losses, SiC devices are identified as a potential technology to improve wind energy generation systems AEP. A 2 MW PM generator based WGS (Wind Generation System) is modeled, and Si IGBT, hybrid and full SiC MOSFET devices are tested in different operation points, as well as different locations. Higher efficiency in the converter based on SiC MOSFETs is observed in all the operation points. This leads to an increment in AEP, mostly in regions with lower average annual wind speeds, making them more interesting for wind energy. The work is replicable tuning the simulation models to obtain precise results for an exact WGS.
