Webrelation between NWP wind speed and SCADA wind speed. Buhan [17] clustered the NWP grid information, and for each cluster, an artificial neural network or support vector machine (SVM) model is constructed to learn the relationship between the wind patterns of NWP data and wind speed data measured by wind tower. WebYan [ 15] established an NWP correction model with multiple inputs and multiple outputs by analysing the deviation patterns between the NWP data and the measured data of the wind tower. However, it only reduces the dimension of NWP and does not improve the accuracy of NWP wind speed prediction.
