Method for establishing wind speed-power conversion probability model

The invention provides a method for establishing a wind speed-power conversion probability model. The method includes the following steps that a history dataset is established; wind speed sections are divided; the probability density of power is estimated; the wind speed-power conversion probability mode is established. A mapping relation between wind speed and wind electricity power is established based on technologies including power probability statistics and the like, accuracy of establishing the wind speed-power probability model is improved, and the efficiency of establishing the model is improved, so that accuracy of predicating the wind electricity power is improved.
