为了智能电网的安全可靠运行，及时检测网络攻击至关重要。此外，考虑到更聪明和更有能力的攻击者，需要强大的检测机制来抵御各种网络攻击。有了这些目的，我们提出了一个强大的在线检测算法（可能结合）虚假数据注入和干扰攻击，还提供了在线估计的未知和随时间变化的攻击参数和恢复状态估计。此外，考虑到更聪明的攻击者，能够设计隐形攻击，以防止检测或增加检测延迟的算法，我们提出了额外的对策。数值研究说明了快速和可靠的响应所提出的检测机制对混合和隐形网络攻击。
For a safe and reliable operation of the smart grid, timely detection of cyber-attacks is of critical importance. Moreover, considering smarter and more capable attackers, robust detection mechanisms are needed against a diverse range of cyber-attacks. With these purposes, we propose a robust online detection algorithm for (possibly combined) false data injection and jamming attacks, that also provides online estimates of the unknown and time-varying attack parameters and recovered state estimates. Further, considering smarter attackers that are capable of designing stealthy attacks to prevent the detection or to increase the detection delay of the proposed algorithm, we propose additional countermeasures. Numerical studies illustrate the quick and reliable response of the proposed detection mechanisms against hybrid and stealthy cyber-attacks.
