This paper mainly proposes a novel distributed secondary event-triggering control strategy for AC islanded microgrid, which not only achieves the consistency of frequency and voltage but also considers the proportional sharing of active power. Compared to the traditional fixed periodic communication, the proposed multiple event-triggered strategy only conducts a sparse communication among distributed generators (DGs). For accelerating the convergence speed and saving the control costs efficiently, a time-varying adaptive updating law for frequency and voltage is proposed. Furthermore, it is confirmed that there is no Zeno behavior. Combined with Lyapunov stability theory, the control strategy is proven to be capable for driving the stability and consistency of microgrid. Finally, three numerical simulations are presented to demonstrate the effectiveness of control mechanisms.
本文主要提出了一种用于交流孤岛微电网的新型分布式二次事件触发控制策略，该策略不仅实现了频率和电压的一致性，还考虑了有功功率的比例分配。与传统的固定周期通信相比，所提出的多事件触发策略仅在分布式电源（DG）之间进行稀疏通信。为了有效加快收敛速度并节省控制成本，提出了一种频率和电压的时变自适应更新律。此外，证实不存在芝诺行为。结合李雅普诺夫稳定性理论，证明该控制策略能够驱动微电网的稳定性和一致性。最后，通过三个数值仿真来证明控制机制的有效性。
