| Summary: | To address the problems of control signal loss and increased frequency deviation， an event-triggering load frequency control （LFC） strategy was proposed to address periodic denial of service （DoS） attacks and time delays in new energy interconnected power systems. First， a new energy-interconnected power system LFC model under network attacks and communication time delay was established. Generalized cross-correlation （GCC） estimation was used to detect online system time delays. A sliding mode control algorithm was used to reduce the impact of time delay and enhance the robustness of the system. Second， an improved periodic event-triggering mechanism was proposed based on the traditional sliding mode control， which determined the sampling state based on the divided time interval to reduce the amount of data exchange in the network and solve periodic DoS attacks. Finally， simulation experiments were conducted under different scenarios using MATLAB/Simulink to demonstrate that the proposed strategy can effectively overcome the problem of increased frequency deviations caused by network attacks and communication delays. This can also improve the frequency stability of new energy-interconnected power systems. |
