About Directions that DC microgrids can take
A DC microgrid can be:run independently of the national (AC) power grid, generating, storing, and transporting its own renewable DC energy, ora grid-connected system, where the incoming AC power supply supports some (or all) of the power provision required, where the AC current is centrally converted to DC before distribution across the microgrid.
