Simplified Solid State Transformer modeling for Real Time Digital Simulator (RTDS)

The Solid State Transformer will be an essential component in the smart grid and it would have made much more impact. This paper proposed a simplified model that is suitable for simulations in RTDS and it is also suitable for general power system studies. While most of the fast dynamics of SST is ignored, all the main control functionalities are kept in this model. The simplified model is tested and verified by comparing with a detail full switching model and cycle-by-cycle average model built in MATLAB and PLECS.
