Abstract  Judging and forecasting types of strong convective weather causing velocity mutation are important to wind power ramping events.By considering the actual wind farm operation of regional power grid,power system operation mode,and the starting speed and capacity of hot standby,the definition of the wind power ramping and decision criteria of ramping weather scenario are determined.Based on this definition,the introduction of the support vector domain description method for wind power ramping scenario classification is used to establish an initializaed extremum model.Through appropriate significant parameters and preliminary classification results,the wind power ramping scenario classification model is established.Then according to the meteorological meaning,typical ramping weather types and related characteristics parameter thresholds are obtained.As a result,the case study shows that the establishment of the wind power ramping scenario classification model and the settled classification thresholds of the significant parameters can provide a good guidance for judging and forecasting the wind power ramping weather types in the target area.
