Abstract: With the increasing proportion of wind turbine units installed capacity year by year, the stability of electric power system frequency is seriously threatened. By configuring energy storage, the pressure of system frequency regulation can be effectively alleviated, but at the same time, it increases investment costs. Therefore, in order to balance the frequency regulation effect and economic benefits, a primary frequency regulation strategy based on the frequency regulation response characteristics of the wind turbine is proposed, which is coordinated with the rotor kinetic energy of the super capacity and doubly fed induction generator(DFIG). Accelerate the reduction of output of the wind turbine rotor under high-frequency operating conditions and continuously monitor subsequent frequency changes. If low-frequency operating conditions occur in the short term, release stored kinetic energy to provide support, forming a wind turbine kinetic energy recovery release mechanism. Under low-frequency conditions, power support is mainly provided by supercapacitors to compensate for the insufficient support capacity of the fan under low-frequency conditions. Finally, based on the actual frequency and wind speed curves, a simulation model is built for DFIG with supercapacitor and the frequency regulation responses of different control strategies are compared in Matlab/Simulink. The simulation results showed that this mechanism can meet the primary frequency regulation requirements while reducing the system’s demand for overcharging and discharging, thereby reducing the economic cost of frequency regulation.
