A Distributed Event-Triggered-Based Control Strategy and its Stability Analysis

This paper investigates the problem of stable control strategy for microgrids with reactive power sharing. Firstly, the idea of multi-agent is introduced to construct the model of microgrid. Then, based on the droop-voltage control, the event-triggered control method is employed to design a control strategy. And an event-triggered-based controller for the reactive power sharing is proposed. Based on those work, the Lyapunov method is introduced to analyze the stability of constructed microgrid system. Finally, a new stability criterion is obtained.
