dcterms.abstractThe invention relates to a method for forecasting short-term wind speed of a wind farm based on data driving. The method comprises the following steps: S1, determining an input variable and an output variable of a relevance vector machine forecasting model according to a preset forecasting time interval; S2, training the relevance vector machine forecasting model by use of a training sample set; and S3, forecasting the wind speed according to the trained relevance vector machine forecasting model to obtain corresponding wind speed forecasting value. The invention also relates to a system for forecasting short-term wind speed of the wind farm based on the data driving. The system comprises a variable determination module for determining the input variable and output variable of the relevance vector machine forecasting model according to the preset forecasting time interval; a training model for training the relevance vector machine forecasting model by use of the training sample set; and a forecasting module for forecasting the wind speed according to the trained relevance vector machine forecasting model to obtain the corresponding wind speed forecasting value. The method provided by the invention is established based on the relevance vector machine, and can accurately forecast the wind speed.-
