摘要: 主要研究了多区域互联电力系统下遭受欺骗攻击的滑模负荷频率控制(load frequency control, LFC)问题. 在考虑欺骗攻击的情况下, 设计了一个龙伯格观测器来观测系统的状态, 利用Lyapunov-Krasovskii (L-K)泛函法构造了一个积分滑模面, 并且给出了系统渐进稳定的充分条件. 然后, 基于观测器的滑模控制器将系统运动轨迹驱使到预先设计的滑模面上, 并使系统最终稳定. 在此基础上, 还引入了事件触发机制, 用以减少控制器更新和节点间通信的频率. 最后, 以一个三区域互联网络电力系统仿真验证了设计方案的有效性.

Abstract: In this paper, the problem of sliding mode load frequency control (LFC) is probed for the multi-area interconnected power system under deception attacks. In the case of deception attacks, a Luenberger observer is designed to generate state estimation of the multi-area power systems. An event-triggered mechanism is introduced to reduce the frequency of controller updates and communication between nodes. Sufficient conditions are proposed to achieve asymptotical stability by utilizing sliding mode control and Lyapunov-Krasovskii (L-K) functional method. Then the sliding mode controller is synthesized to ensure that the trajectory of the closed-loop system can be driven onto the prescribed sliding surface. Finally, the effectiveness of the design scheme is verified by a three-area interconnected power system.

Key words: Load frequency control, deception attacks, sliding mode control, event-triggering mechanism
