Offshore wind farms are becoming increasingly distant from onshore centralized control centers

and the communication delays between them inevitably introduce time delays in the measurement signal of the primary frequency control. This causes a deterioration in the performance of the primary frequency control and

in some cases

may even result in frequency instability within the power system. Therefore

a frequency response model that incorporates communication delays was established for power systems that integrate offshore wind power. The Padé approximation was used to model the time delays

and a linearized frequency response model of the power system was derived to investigate the frequency stability under different time delays. The influences of the wind power proportion and frequency control parameters on the system frequency stability were explored. In addition

a Smith delay compensation control strategy was devised to mitigate the effects of communication delays on the system frequency dynamics. Finally

a power system incorporating offshore wind power was constructed using the MATLAB/Simulink platform. The simulation results demonstrate the effectiveness and robustness of the proposed delay compensation control strategy.
