在本研究中，为智能电网开发了一种基于带宽分配的分布式事件触发负载频率控制（LFC），以应对混合网络攻击，例如拒绝服务（DoS）攻击和虚假数据注入（FDI）攻击。首先，为了防止混合网络攻击导致 LFC 系统开环不稳定运行，我们提出了分布式事件触发通信（ETC）策略。为了实现带宽的最大利用，基于资源可用性以及当前状态与平衡状态之间的误差，动态带宽分配机制与ETC方法相结合。这种带宽预留和分配方法旨在检测攻击并将带宽分配给分发网络的不同通道。然后，借助Lyapunov方法，建立了指数稳定性判据。此外，在控制过程中证明了所设计系统的芝诺行为的排除性。最后，综合案例研究表明，该方法能够提高网络资源的利用率。
In this study, a bandwidth allocation-based distributed event-triggering load frequency control (LFC) has been developed for smart grids to deal with hybrid cyber-attacks, for example, denial-of-service (DoS) attacks and false data injection (FDI) attacks. Firstly, to prevent hybrid cyber-attacks from causing open-loop unstable operation of the LFC systems, we propose a distributed event-triggering communication (ETC) strategy. To attain the maximum usage of bandwidth, a dynamic bandwidth allocation mechanism is integrated with the ETC approach on the basis of resource availability and error between the current state and equilibrium state. This bandwidth reservation and allocation approach aim at detecting attacks and assigning bandwidth to the different channels of distribution networks. Then, by virtue of the Lyapunov approach, the exponential stability criteria are established. Further, the exclusion of Zeno behavior of the designed systems is proved during the control process. Finally, comprehensive case studies show that the proposed method can improve the utilization rate of the network resource.
