摘　　要：针对孤岛交流微电网控制系统中不可避免的虚假数据注入攻击问题,当存在外部干扰时,设计了主动容侵控制策略。首先针对孤岛交流微电网逆变系统,构建系统状态空间模型。将控制系统传感器侧可能受到的虚假数据注入攻击信息当作一个辅助状态向量,设计滑模攻击观测器对系统中的状态变量和虚假数据注入攻击信息同时进行估计。在获得攻击的估计信息后,利用积分滑模容侵控制器对虚假数据注入攻击和外部有限能量干扰进行主动容侵控制,以确保微电网系统的稳定运行。最后,通过仿真验证了所提方法的可行性和有效性。In this paper,an active intrusion tolerance control strategy is designed for the inevitable false data injection attack in the control system of island AC microgrid when there is external interference.Firstly,the state space model of the island AC microgrid inverter system is constructed.A sliding-mode attack observer is designed to estimate both the state variables and the false data injection attack information in the control system.After obtaining the estimated information of the attack,the integrated sliding mode intrusion tolerance controller is used to actively control the false data injection attack and external finite energy interference to ensure the stable operation of the microgrid system.Finally,the feasibility and effectiveness of the proposed method are verified by simulation.
