Abstract

A system includes a power source configured to provide constant-current power to a medium-voltage direct current (MVDC) bus. The system also includes a first rotating electrical machine configured to receive the power from the MVDC bus. The system further includes a plurality of second rotating electrical machines connected in series with the first rotating electrical machine, with a long distance transmission line between adjacent rotating electrical machines. In addition, the system includes a flywheel energy storage coupled to each of the rotating electrical machines, where each flywheel energy storage is configured to store inertial energy. Each of the rotating electrical machines is electrically connected to a battery or ultra-capacitor subsystem and a pulse forming network (PFN).
