本文研究了微电网集群之间的有功功率共享问题，该集群由一组交流和直流微电网通过一组互连转换器（IC）网络互连而形成。提出了一种基于事件的分布式一致性控制方法，每个IC被分配为一个Agent，只需要其本地和相邻IC的信息。我们首先为每个IC构造代理系统，并设计其一致性控制协议。该控制机制采用协作方式间接调节各个微网的有功负荷，从而实现微网间的有功潮流导航。因此，可以按比例实现互连微电网之间的有功功率共享。然后，一个基于事件的控制方案被用来设计共识协议，它可以显着减少IC之间的通信。还考虑了通信时间延迟和无功功率支持。该分布式控制方法允许稀疏的通信结构和更高的可靠性和灵活性操作。仿真结果证明了所提出的控制方法。
This paper investigates the issue of active power sharing among a cluster of microgrids formed by a set of ac and dc microgrids network-interconnected through a set of interlinking converters (ICs). An event-based distributed consensus control approach is proposed to address this issue, in which each IC is assigned to be an agent that needs only the information of its local and neighboring ICs. We first construct the agent system for each IC and design its consensus control protocol. This control mechanism uses a cooperative approach to indirectly adjust the active power load of individual microgrid and, accordingly, navigate the active power flow among them. Thus active power sharing among the interconnected microgrids can be achieved proportionally. Then, an event-based control scheme is utilized to design the consensus protocol, which can dramatically reduce the communication between ICs. Communication time delays and reactive power support are also considered. The proposed distributed control method allows a sparse communication structure and higher reliability and flexibility operation. Simulation results are presented to demonstrate the proposed control method.
