The DC microgrid provides a flexibility of using DC-based distributed sources (PV, storage, etc.) and electronic devices and loads such as electric vehicles, laptops, chargers, and so on. The energy from DC sources, often after processing by DC-DC converter, is utilized directly by DC loads.
Two ways to ensure continuous electricity regardless of the weather or an unforeseen event are by using distributed energy resources (DER) and microgrids. DER produce and supply electricity on a small scale and are spread out over a wide area. Rooftop solar panels, backup batteries, and emergency diesel generators are examples of DER.
