In this paper, the issue of interarea oscillations in wide-area power systems with false data injection (FDI) attacks is studied. A wide-area robust sliding mode controller (WARSMC) is proposed to defense the hacker attacks and damp out the interarea oscillations. First, an extended observer is designed to estimate the states and defense actuator attacks simultaneously. Then, a WARSMC based on the estimated states is presented. In which a new sliding function is constructed, meanwhile, the new reaching law is designed. Furthermore, the system dynamics under designed control law is analyzed and the convergence of the proposed algorithm is proved. Finally, the case studies are based on the two-area four-machine and the 16-machine 68-bus power system. Simulation results verify the effectiveness of the designed method for defensing the FDI attacks and damping out the interarea oscillations.

具有错误数据注入攻击的电力系统广域鲁棒滑模控制器

本文研究了带有误数据注入（FDI）攻击的广域电力系统中的区域间振荡问题。提出了一种广域鲁棒滑模控制器（WARSMC）来防御黑客攻击并抑制区域间振荡。首先，设计一个扩展的观察者以同时估计状态和防御执行器的攻击。然后，提出了基于估计状态的WARSMC。在构造新的滑动函数的同时，设计了新的到达律。此外，分析了设计控制律下的系统动力学，并证明了该算法的收敛性。最后，案例研究基于两区四机和16机68总线电源系统。
