Its purpose is to enable the flexible and efficient use of distributed power sources, address distributed power grid integration issues, promote the large-scale integration of distributed power sources and renewable energy, and improve power supply reliability and energy efficiency. Microgrids require the use of a DC power supply, a device that maintains a constant voltage and current in a circuit.
