A data-driven LFC system is proposed to address the performance issues caused by uncertain factors such as random de-lay,packet loss,and load fluctuations in load frequency control.By establishing a decentralized control structure,optimizing feedback variables,and proposing a selective event triggered controller,communication resource consumption has been reduced and the opera-tional efficiency of the system has been improved.The simulation results show that compared with H ∞ control and PSO-PI control strategies,SETC control not only shortens PTFD by 76.7％and 23.2％,but also reduces FRST by 64.5％and 17.2％,respective-ly.The design of SETC not only balances the relationship between reduced communication and system performance,but also demon-strates excellent recovery capability and robustness,which is of great significance for improving the flexibility and reliability of power systems.
