With large-scale and high penetration level wind integration, it is difficult to meet power grid need when only conventional units participate in primary frequency modulation, so the participation of wind power is urgently needed. Based on the research of wind power frequency modulation control, a unit commitment model considering the wind turbines participating in primary frequency modulation is proposed. By systematically adding the constraints of steady-state frequency, minimum frequency and rate of change-of-frequency, the model ensures that enough spare capacity is reserved to support primary frequency modulation. The big M method is used to transform the nonlinear model into a mixed integer linear programming model, and then the CPLEX package of Matlab is used to solve the problem. Finally, the validity of the proposed model is verified on IEEE 39-bus system. The simulation results show that the proposed model can improve the capacity of the system to withstand load disturbance, so as to meet the standby requirement of primary frequency modulation under larger load disturbance.
