在本文中，我们研究了潜在的状态相关的假数据注入网络攻击对孤岛交流微电网频率同步和有功功率管理的影响。影响微电网可靠性的一种潜在方法是迫使发电中断。因此，攻击者可能会通过恶意注入操纵其频率来破坏微电网中基于逆变器的资源的同步。攻击信号被注入以操纵控制输入通道、传感器节点、参考值以及通过通信网络交换的信息。为了减轻此类网络攻击的不利影响，首先，在存在网络攻击的情况下，对传统的基于分布式共识的二次控制方法进行了修改和补充。其次，利用虚拟层与主网络层互联的概念，提出了一种弹性协同分布式二次控制方案。第三，提供了互连矩阵的理论稳定性、弹性分析和设计考虑。最后，通过MATLAB/Simulink仿真和实验结果验证了所提控制方案的鲁棒性。
In this article, we investigate the impact of potential state-dependent false data injection cyber-attacks on frequency synchronization and active power management in islanded ac microgrids. One potential way of affecting microgrid reliability is by forcing a generation outage. Thus, the attacker could potentially aim to desynchronize inverter-based resources in microgrids by manipulating their frequency with malicious injections. The attack signals are injected to manipulate control input channels, sensor nodes, reference values, and the information exchanged through communication networks. In order to mitigate the adverse impacts of such cyber-attacks, first, the conventional distributed consensus-based secondary control approach is modified and complemented in the presence of cyber-attacks. Second, a resilient cooperative distributed secondary control scheme is proposed by utilizing the concept of a virtual layer interconnected with the main network layer. Third, theoretical stability, resilience analysis, and design considerations of interconnection matrices are also provided. Finally, simulations through MATLAB/Simulink and experimental results are presented in order to illustrate the robust performance of the proposed control scheme.
