针对交流微电网中大规模分布式发电机的频率同步问题，提出了一种新的分布式事件触发控制方法。所提出的基于事件通信机制的基于共识的分布式频率控制策略是完全分布式的，并且只在自己的事件时间触发，与连续时间反馈控制相比，有效地降低了控制器的更新频率。此外，每个DG只需要在最后一个事件触发时间使用低带宽通信链路进行分布式控制，从自己和一些最近的邻居（但不是全部）进行本地电压和电流测量。设计了通信拓扑对渐近跟踪期望值的最小要求。在MATLAB/SimPowerSystems的微电网系统中进行了仿真研究，验证了所提控制方法的有效性。
A novel distributed event-triggered control method is presented for frequency synchronization of massive distributed generators (DG) in ac microgirds. The proposed consensus-based distributed frequency control strategy based on the event-based communication mechanism is fully distributed and only triggered at their own event time, which effectively reduces the frequency of controller updates compared with continuous-time feedback control. Moreover, each DG only requires the local voltage and current measurement from its own and some nearest neighbors (but not all) for the distributed control at the last event-trigger time by using low-bandwidth communication links. The minimum requirement on communication topologies to asymptotically track desired values is devised. Simulation studies in a microgrid system of MATLAB/SimPowerSystems demonstrate the effectiveness of the proposed control method.
