Abstract：Recently, the concept of cyber physical system (CPS) has been widely applied in micro-grid. But it has also caused a lot of communication problems. Therefore, an event-triggered hierarchical control strategy is proposed in this paper. It’s used to improve the control effect on the obtained voltages and frequency by droop control of distributed energy resources (DERs) when considering with packet loss and communication disturbance. The structure of the control strategy is divided into the cyber layer and the physical layer. In the cyber layer: A novel virtual leader-following consensus control (VLFCC) and a predictive compensation method combined with extreme learning mechanism (ELM) and model predictive control (MPC) is designed to solve the problem of packet loss; A method combined with sliding mode control (SMC) and the VLFCC (SVLFCC) is designed to solve the problem of communication disturbance. And the implementations of the above methods are based on event-trigger mechanisms. In the physical layer: Based on the proposed event-trigger mechanisms, a secondary control method on DERs is designed in this layer. Finally, the effectiveness of the proposedhierarchical control strategy is verified by simulation experiments.
