Due to the attack signal injection on the DC microgrid system, voltage regulation and current sharing cannot be guaranteed and the overall system may even be destabilized. To solve this problem, a generalized extended state observer (GESO)-based distributed attack-resilient control method is proposed for DC microgrids in this paper. The presented control scheme can detect and mitigate the unknown dc/low-frequency/grid-frequency attack signals while achieving voltage regulation and accurate current sharing among distributed generation (DG) units. In addition, benefiting from employing the proposed distributed control strategy, the information exchange among the DG units is updated in an aperiodic way. As a result, the communication burden of the DC microgrid communication network can be greatly reduced. The stability of the proposed method is verified by the Lyapunov function, and no Zeno behavior will exist. Finally, the experimental results are illustrated to validate the effectiveness of the proposed approach.

直流微电网基于广义扩展状态观测器的分布式抗攻击控制



由于攻击信号注入直流微电网系统,无法保证调压和均流,甚至可能导致整个系统失稳。针对这一问题,本文提出了一种基于广义扩展状态观测器(GESO)的直流微电网分布式抗攻击控制方法。所提出的控制方案可以检测和减轻未知的直流/低频/电网频率攻击信号,同时实现分布式发电(DG)单元之间的电压调节和精确均流。此外,受益于采用所提出的分布式控制策略,DG 单元之间的信息交换以非周期性方式更新。从而可以大大减轻直流微电网通信网络的通信负担。通过Lyapunov函数验证了该方法的稳定性,并且不会存在Zeno行为。最后,通过实验结果验证了所提方法的有效性。
