摘要:

针对互联电力系统负荷频率控制通信网络带宽受限及易遭受恶意网络攻击的问题,文中研究了拒绝服务攻击下弹性事件触发机制和负荷频率控制器的联合设计问题。在拒绝服务攻击参数已知的情况下,提出了一种既能缓解通信带宽压力,又可同时消除拒绝服务攻击影响的弹性事件触发机制。文中构建了一种基于弹性事件触发机制及拒绝服务攻击的负荷频率控制时滞切换系统模型。应用分段李亚普洛夫函数对切换系统稳定性进行了分析,并进行了触发参数和控制器的联合设计。最后,通过一个两区域互联电力系统仿真验证了所提方法的有效性。

Abstract:

Focusing on the scenario that the communication network of load frequency control for multi-area power systems is bandwidth-constrained and subject to Denial-of-Service attacks, the problem of the co-design for resilient event-triggered communication scheme and controller was investigated in this study. As DoS parameter is well known, a resilient event-triggered communication scheme was proposed, which could ease the pressure on network bandwidth and eliminated the impact of DoS attacks. In addition, a switched time delay system model was also formulated. The system stability was analyzed by using the piecewise Lyapunov function, and a co-design method for triggered parameter and controller was designed. Finally, the effectiveness of the proposed method was demonstrated with a two-area power system.

Key words: load frequency control, denialof service attacks, event-triggered control, networked control system, cyber physical system, exponential stability
