With the large-scale integration of renewable energy and the increasing penetration of wind power in power systems

the pressure on system frequency regulation is escalating

posing new challenges to grid stability.To address this issue

this paper proposes a primary frequency regulation control strategy based on rotor speed and the rate of change of system frequency(RoCoF).A logistic function with self-regulating characteristics is introduced to construct an adaptive droop coefficient adjustment mechanism that can respond in real-time to the rotor kinetic energy state.The RoCoF is further incorporated as a dynamic adjustment parameter

enabling rapid tuning of the droop coefficient during sudden frequency drops to shorten the response delay of wind turbines.A doubly-fed induction generator-based wind turbine simulation model is established on the SIMULINK/MATLAB.Simulation results show that the proposed strategy effectively suppresses the maximum frequency deviation and reduces the frequency recovery time.
