直流微电网分布式协同控制比传统集中式控制更具灵活性,但分布式控制架构使其更容易遭受网络攻击。虚假数据注入(FDI)攻击作为一种常见的网络攻击形式,可以改变系统的运行状态甚至破坏微电网系统的稳定性。为此,文中研究了一类无界FDI攻击下的直流微电网电流分配和电压恢复问题,提出了一种集FDI攻击检测和系统恢复于一体的控制方法。首先,设计了一种基于总输出电流和母线电压反馈的残差评估函数,通过实时监测该函数值与设定阈值的关系实现FDI攻击检测。在此基础上,提出了一种基于分散式滑模观测器的直流微电网电流分配和电压恢复的弹性控制策略,以抵御并消除FDI攻击影响。最后,通过仿真案例验证了该方法的有效性。
The distributed cooperative control of DC microgrid is more flexible than the traditional centralized control
but distributed control architecture makes it more vulnerable to network attacks. As a common form of network attack
the false data injection (FDI) attack can change the operation state of the system and even destroy the stability of the microgrid. Therefore
this paper studies the current distribution and voltage recovery of DC microgrid under a class of unbounded FDI attacks
and proposes a control method integrating FDI attack detection and system recovery. First
a residual evaluation function based on the total output current and bus voltage feedback is designed
and FDI attack detection is realized by monitoring the relationship between the function value and the set threshold value in real time. On this basis
a resilient control strategy of current distribution and voltage recovery in DC microgrid based on the decentralized sliding mode observer is proposed to resist and eliminate the impact of FDI attacks. Finally
the effectiveness of the method is verified by a simulation case
