摘要:

随着电力系统的数字化发展,电力系统中监控与数据采集网络带来了网络安全风险,文章聚焦于车网互联电力系统在拒绝服务攻击下的主动防御体系构建,首先构建了车网互联电力系统的负载频率控制架构,通过引入动态事件触发方案设计优化通信效率,以降低网络带宽占用。同时提出一种监督重启控制器策略,该策略对控制器反馈进行实时监测,当检测到控制器反馈异常时,触发控制器动态重启以主动隔离异常。然后,通过构造合适的Lyapunov-Krasovskii函数,推导出系统在拒绝服务攻击下的指数稳定性判据,为防御策略参数设计提供量化依据。最后,通过仿真实验验证了所提方案的有效性。

Abstract:

With the digital development of power systems, the monitoring and data acquisition networks in power systems bring network security risks. This paper study focused on the construction of an active defense strategy under denial-of-service (DoS) attacks in vehicle-to-grid power systems. Firstly, a load-frequency control strategy was constructed for the power system, and a dynamic event triggering scheme design was introduced to optimize the communication efficiency in order to reduce the network bandwidth consumption. Besieds, a supervised restart controller algorithm was proposed, which monitored the controller response in real time, and triggered the controller to restart dynamically when an abnormality was detected. Further, by constructing appropriate Lyapunov-Krasovskii functionals, the exponential stability criterion of the system under DoS attacks was derived, which provided a quantitative basis for the parameter design of the defense strategy. Finally, the effectiveness of the proposed scheme is verified by simulation experiment.
