Due to the droop control applied in islanded DC microgrids, DC bus voltage recovery, and current sharing cannot be guaranteed simultaneously. To solve this problem, a distributed dynamic event-triggered control method is proposed in this paper. The presented control scheme can remove DC bus voltage deviation while achieving the current sharing among distributed generation (DG) units. In addition, the proposed method requires no global information, and only the DC bus voltage from the physical network is needed. Moreover, the data of neighboring DGs at only event-triggered times are involved, which greatly reduces the communication burden of the DC microgrid communication network. The stability of the proposed method is demonstrated through the Lyapunov function, and Zeno behavior can be excluded as well. Finally, the experimental results with four case studies are presented to validate the effectiveness of the proposed method.

直流微电网电压恢复和均流的分布式动态事件触发控制

由于孤岛直流微电网采用下垂控制，因此无法同时保证直流母线电压恢复和均流。针对这一问题，本文提出了一种分布式动态事件触发控制方法。所提出的控制方案可以消除直流母线电压偏差，同时实现分布式发电 (DG) 单元之间的电流共享。此外，所提出的方法不需要全局信息，只需要来自物理网络的直流母线电压。而且，仅涉及相邻DGs的事件触发数据，大大减轻了直流微电网通信网络的通信负担。所提出方法的稳定性通过李雅普诺夫函数证明，并且芝诺行为也可以被排除。最后，
