Transient analysis of low voltage DC grids with high penetration of DERs

Abstract

High penetration of Distributed Energy Resources (DERs) with different dynamic responses cause interaction between components in a DC microgrid. This paper proposes a method called object-oriented modeling, which allows analyzing converter-interfaced DC microgrids in steady states and transients. The analysis mainly focuses on transient behavior of external electric values, as well as internal controller states.
