This paper investigates the load frequency stability of power systems within networked environments. In a networked environment, there may be packet loss when network transmission channel transmits signals, which affects the fluctuation of load frequency in power system. In view of this phenomenon, an auxiliary random sequence is proposed to represent the overall data flow in networked power system. Furthermore, in order to preserve scarce network bandwidth, the event triggered scheme and network factors are simultaneously analyzed, and the controller is devised to uphold the stability of the closed-loop system concerning the actual input states. Ultimately, simulation experiments are conducted on the interconnected power system spanning two regions. These simulations aim to validate the efficacy of modeling networked data flow and to ensure the stability of load frequency control within the power system’s operational framework.
