| description | The invention provides a direct-current microgrid system for electric vehicles and a control method thereof. The DC microgrid system is adopted as an intermediate system between a public network and an electric vehicle, so that the stability of a public network system can be better protected; the DC microgrid system can reduce the number of times of electric energy conversion and improve the electric energy utilization efficiency; a bidirectional AC/DC converter is adopted to connect the public network and the DC microgrid system, and the stability of the two systems is adjusted through bidirectional flow control of energy; and meanwhile, a bidirectional charging device is designed, a discharging function is provided for a large number of electric vehicle storage batteries connected into the DC microgrid system, charging and discharging control is conducted in combination with user benefits and system stability, internal stability of the DC microgrid system can be maintained, the burden of the public network |
