were coupled with ensemble empirical mode decomposition (EEMD) and Grey wolf algorithm (GWO) to construct hybrid models to predict wind speed of Huan County wind farm in Longdong area of Loess Plateau in China. And then the forecasting results of each hybrid model were taken as input variables
and the minimum sum of squares of prediction errors was regarded as the objective function
the combined model without negative constraint theory (NNCT) was proposed to realize the accurate prediction of wind speed in the study area
while the weight of the combined model was optimized by using GWO algorithm. Numerical simulation results show that the GWO-NNCT model can effectively reduce the risk of model selection and has higher prediction accuracy than that of the hybrid models and single machine learning model.
