AC and DC hybrid micro grid coordinated control system

The present invention relates to an AC and DC hybrid micro grid coordinated control system which comprises an AC micro grid and a DC micro grid. The AC micro grid comprises an AC bus. The DC micro grid comprises a DC bus. The AC bus and the DC bus are connected through a coordination controller. According to a construction target, an AC and DC hybrid micro grid is connected to a public connection point PCC through the AC bus or the DC bus and is connected to an AC or DC grid. The energy storage device of the AC micro grid is connected to the AC bus through an energy storage inverter. The energy storage device of the DC micro grid is connected to the DC bus through an energy storage converter. The invention provides the AC and DC hybrid micro grid coordinated control system, the system can be adapted to multiple operation modes of the hybrid micro grid and is effectively adapted to the needs of different construction targets, through the above control mode based on the two hybrid micro grids, and the stable control of AC and DC hybrid micro grid under different operation modes can be realized.
