交直流混合微电网协调控制系统
摘要：
本发明涉及一种交直流混合微电网协调控制系统，包括交流微电网和直流微电网，交流微电网包括交流母线，直流微电网包括直流母线，交流母线和直流母线之间通过协调控制器连接，根据建设目标将交直流混合微电网通过交流母线或者直流母线连接公共连接点PCC并入交流或直流电网；交流微电网的储能装置通过储能逆变器连接到交流母线；直流微电网的储能装置通过储能变流器连接到直流母线。本发明提供的一种交直流混合微电网协调控制系统，能够适应混合微电网的多种运行模式，有效的适应不同建设目标的需要；通过基于上述两种混合微电网进行的控制方式，能够很好的实现混合微电网的不同运行模式下交直流混合微电网的稳定控制。
摘要（英）：

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.
