摘　　要：为应对可再生能源大量并网和网络传输安全问题,研究了异构多区域电力系统HMAPSs(heterogeneous multi-area power systems)在切换网络攻击下的的负荷频率控制。首先,提出了一种带有能量受限的具有非周期拒绝服务DoS(denial of service)攻击和随机虚假数据注入FDI(false data injection)攻击在时间域上切换的切换网络攻击模型。接着,设计了一种基于确认ACK(acknowledgement)机制的弹性事件触发方案。进一步,通过Lyapunov稳定性理论和切换系统方法,导出了切换网络攻击下HMAPSs的均方指数稳定性判据。最后,仿真实验结果验证了所提方法的有效性。To cope with incorporating a large amount of renewable energy into the grid and the issue of cyber security,the load frequency control of heterogeneous multi-area power systems(HMAPSs)under switching cyber attacks is studied in this paper.First,a model of energy-limited switching cyber attacks is proposed,in which aperiodic denial of service(DoS)attacks and random false data injection(FDI)attacks switch in the time domain.Second,a resilient eventtriggered scheme based on the acknowledgement(ACK)mechanism is designed.Furthermore,the exponential meansquare stability criterion for HMAPSs under switching cyber attacks is derived by the Lyapunov stability theory and the switching system method.The results of numerical simulations verify the effectiveness of the proposed method.
