CONTROL DEVICE FOR DC MICROGRID AND CONTROL METHOD THEREOF, DC MICROGRID SYSTEM

摘要

The present invention provides a control device for a direct-current (DC) microgrid and a control method thereof, and a DC microgrid system. The control device of a DC microgrid comprises a detection module configured for detecting a voltage change rate of the DC bus, and a regulation module configured for regulating energy compensation by the energy compensation means to the DC bus based on the voltage change rate of the DC bus that is detected by the detection module. In the control device for a DC microgrid provided by the present invention, the detection module detects in real time the condition of voltage change of the DC bus, and the control module regulates in real time the energy compensation by the energy compensation means to the DC bus based on the result detected by the detection module, such that stability of voltage of the DC bus is increased, and the DC microgrid can be operated stably.
