摘要: 针对网络化的微电网系统中存在通信延时、高采样率、控制器更新次数多等问题,将事件驱动方法与一致性算法结合,提出一种基于事件驱动一致性的微电网系统分布式协同控制方法.将分布式电源作为分布式稀疏网络中的智能节点,应用一致性算法设计状态观测器,根据智能节点的状态信息设计事件触发条件.当事件触发时,观测器将实际状态值传输到控制器,同时向邻居控制器传输信息.该控制方法要求分布式控制器在事件触发时进行通信,能有效减少控制器更新次数,降低系统对网络带宽的要求.利用Lyapunov函数分析了控制系统的稳定性.最后,搭建MATLAB/Simulink仿真平台,验证了所提控制方法在通信延时下具有良好的动态性能.

Abstract: There are some problems such as communication delay, high sampling rate, and frequent controller updates in the networked microgrid system, the paper proposes a distributed coordination control method for a microgrid system based on event-triggered consensus algorithm, which combines the event-triggered method with the consensus algorithm. The distributed generation unit is an intelligent node in the distributed sparse network, and the state observer is designed using the consensus algorithm, and designs event-triggered conditions based on the state information of smart nodes. When an event is triggered, the observer transmits the actual state value to the controller, while also sharing the information to the neighbor controller. This control method requires the distributed controller to communicate when the event is triggered, effectively reducing the number of controller updates and minimizing thesystem’s requirements for network bandwidth. The stability of the control system was analyzed by the Lyapunov function. Finally, simulation platform is built by Matlab/Simulink simulation software to validate the proposed control method, demonstrating its robustness dynamic performance under communication delay.
