摘要:

随着网络化电力系统复杂程度越来越高,传统的控制方案很难满足实际需求,带宽受限、网络安全,以及执行器饱和等问题成为影响电力系统稳定性的重要因素。针对带宽资源受限问题,引入改进的事件触发机制以提高带宽资源的利用率;同时,构造欺骗攻击和执行器饱和下的电力系统新的数学模型;基于该系统模型,根据Lyapunov理论推导出电力系统稳定的充分条件,并利用线性矩阵不等式(LMI)技术,给出安全控制器的设计方案;最后,通过一个电力系统实例来说明所提方案的有效性。

关键词: 网络控制系统, 自适应事件触发机制, 网络攻击, 执行器饱和

Abstract:

With the increasing complexity of networked power systems, traditional control schemes are difficult to meet the actual needs. Bandwidth constraints, network security and actuator saturation have become important factors affecting the stability of power systems. An improved event trigger mechanism was introduced to improve the utilization rate of bandwidth resources for the problem of bandwidth resource limitation, and a new mathematical model of power system under deception attack and actuator saturation was constructed. Based on this number model, the sufficient conditions for the asymptotic stability of the power system were obtained by Lyapunov theory, and the design scheme of the security controller was given by using linear matrix inequality technique. Finally, an example of power system was given to illustrate the effectiveness of the proposed scheme.

Key words: Network control systems, Adaptive event triggering mechanism, Network attacks, Actuator saturation
