  • 摘要: 本文将电动汽车(Electric vehicles,EVs)引入到典型的信息物理系统(Cyber-physical systems,CPS)智能电网中,采用负荷频率控制(Load frequency control,LFC)方法,能够快速抑制系统扰动所引发的频率变化.在考虑拒绝服务(Denial-of-Service,DoS)攻击的情况下,提出了一种弹性事件触发机制,使系统能够容忍攻击所造成的数据丢失.与此同时,PI型静态输出反馈控制器的输入按需更新,减少了通信负担.对于建立的闭环时滞系统模型,构造新型李亚普诺夫泛函,对系统进行稳定性分析,推导出系统所能承受的最大DoS攻击持续时间,并对控制器增益和弹性事件触发矩阵进行协同设计.最后,通过多域电力系统仿真,验证了所提出方法的有效性.
