With the increase of wind power permeability

the randomness of the system is further enhanced

while the traditional way of providing primary frequency regulation（PFR） reserve only for conventional units will lead to serious shortage of system reserve.Therefore

the adaptive control mode of wind turbine participating in PFR of the system is studied in this paper.Firstly

the de-loaded operation mode of reserving PFR reserve for wind turbines is studied.Secondly

the adaptive control mode of wind turbines participating in PFR is studied on the basis of traditional PFR control mode of wind turbines.Its virtual inertia parameters and droop control parameters can be adaptively adjusted with the actual operating state of the wind turbine and the system frequency.It is shown by the study that the adaptive control method adopted in this paper will further enhance the stability and security of the system.
