Malicious traffic attack can prolong the transmission delay of normal data flows by exhausting the limited bandwidth with injecting numerous invalid data packets. For the networked load frequency control (LFC) systems, the traffic attacks can cause the control performance deterioration or even instability. In this paper, an adaptive LFC scheme where the controller gains can be flexibly adjusted according to the attack intensities is proposed. Firstly, to quantitatively evaluate the impact of traffic attacks on the network transmission performance, the relationship between attack intensity and transmission delay bounds of normal data flows in multi-hop transmission process is well revealed based on deterministic network calculus. Secondly, to alleviate the adverse impacts of traffic attacks and improve the control performance under low-level attack intensities, the studied systems are described as a series of subsystems with the actual transmission delays of normal data flows as the switching decisions. Thirdly, a controller bank corresponding to all the attack intensities is elaborately constructed. The constraints and update criteria of each controller in the bank are strictly deduced in the switching control framework. Finally, the effectiveness of the proposed adaptive method is verified by four case studies.

恶意流量攻击下互联电力系统的攻击强度依赖自适应负载频率控制

恶意流量攻击可以通过注入大量无效数据包来耗尽有限带宽,从而延长正常数据流的传输延迟。对于网络负载频率控制(LFC)系统,流量攻击会导致控制性能恶化甚至不稳定。在本文中,提出了一种自适应 LFC 方案,其中控制器增益可以根据攻击强度灵活调整。首先,为了定量评估流量攻击对网络传输性能的影响,基于确定性网络演算很好地揭示了多跳传输过程中正常数据流的攻击强度与传输延迟界限之间的关系。第二,为了减轻流量攻击的不利影响并提高低级攻击强度下的控制性能,将研究的系统描述为一系列子系统,以正常数据流的实际传输延迟作为切换决策。第三,精心构建了对应所有攻击强度的控制器库。银行中每个控制器的约束和更新准则在交换控制框架中被严格推导。最后,通过四个案例研究验证了所提出的自适应方法的有效性。银行中每个控制器的约束和更新准则在交换控制框架中被严格推导。最后,通过四个案例研究验证了所提出的自适应方法的有效性。银行中每个控制器的约束和更新准则在交换控制框架中被严格推导。最后,通过四个案例研究验证了所提出的自适应方法的有效性。
