Abstract

In this paper, the distributed secondary voltage and frequency restoration problem is addressed in AC microgrid systems subjected to hybrid false data injection (FDI) and denial-of-service (DoS) attacks. Firstly, a new distributed resilient iterative estimator based on the k-step estimation method is proposed that can accurately estimate the FDI attack signals as well as the voltage and frequency of each distributed generation (DG) even under the impact of DoS attacks. Then, based on the mean value of the attack estimation signal, a distributed resilient secondary controller is designed to compensate for the considered hybrid attacks. Compared with existing researches on resilient control of AC microgrids under hybrid attacks, the voltage and frequency regulation errors of the microgrid system converge to zero for the first time. Finally, the precise convergence of voltage and frequency in the AC microgrid system under the proposed method is verified through a real-time controller-hardware-in-the-loop experiment in OPAL-RT.

针对混合攻击的交流微电网分布式弹性二级控制

本文探讨了交流微电网系统在受到混合虚假数据注入（FDI）和拒绝服务（DoS）攻击时的分布式二次电压和频率恢复问题。首先，提出了一种基于 k 步估计法的新型分布式弹性迭代估计器，即使在 DoS 攻击的影响下，也能准确估计 FDI 攻击信号以及各分布式发电（DG）的电压和频率。然后，基于攻击估计信号的平均值，设计了一种分布式弹性二次控制器来补偿所考虑的混合攻击。与现有的混合攻击下交流微电网弹性控制研究相比，微电网系统的电压和频率调节误差首次收敛为零。最后，通过在 OPAL-RT 中进行实时控制器-硬件在环实验，验证了所提方法下交流微电网系统电压和频率的精确收敛性。
