Why are DC microgrids more attractive?

Most distributed generation (DG) systems now use storage and offer DC power to their loads, making DC microgrids more attractive. As more RE sources are added to the grid, the system’s rotational inertia diminishes because Power Electronic Converters (PECs) do not contribute any.
