Abstract:
This paper touches on three key areas of full electronic DC grid systems, in particular Medium Voltage DC (MVDC) grids, and presents advances at optimized DC grid planning, control stability, and efficient power converters. A solution of the specific mathematical optimization problem of DC grids allows targeted optimization while considering their unique flexibility. An advanced control approach demonstrates voltage stability, independent of grid configuration. A robust soft-switching extension to the DAB converter extends high-efficient operation to the full operation area.
