In view of a sensitive frequency band existing in wind power fluctuation, the invention provides a wind power stabilization control method based on a digital band stop filter. Through designing a control algorithm for the digital band stop filter, corresponding parameters are changed, the central frequency and the bandwidth of the filter are adjusted, the parameters are applied to a wind power stabilization control system, improvement effects on the wind farm fluctuation power stabilization control by the control algorithm for the band stop filter are analyzed, and target reference power in need of throughput by an energy storage system is obtained, the control effect that the energy storage system and the filter are matched to together stabilize wind power fluctuation can be realized, the fluctuation power can be extracted accurately, the target power for throughput by the energy storage system is clear, and the method is scientific, reasonable, strong in applicability and good in effects.
