Abstract EN
Short-term wind speed forecasting is crucial to the utilization of wind energy, and it has been employed widely in turbine regulation, electricity market clearing, and preload sharing.
However, the wind speed has inherent fluctuation, and accurate wind speed prediction is challenging.
This paper aims to propose a hybrid forecasting approach of short-term wind speed based on a novel signal processing algorithm, a wrapper-based feature selection method, the state-of-art optimization algorithm, ensemble learning, and an efficient artificial neural network.
Variational mode decomposition (VMD) is employed to decompose the original wind time-series into sublayer modes.
The binary bat algorithm (BBA) is used to complete the feature selection.
Bayesian optimization (BO) fine-tuned online sequential extreme learning machine (OSELM) is proposed to forecast the low-frequency sublayers of VMD.
Bagging-based ensemble OSELM is proposed to forecast high-frequency sublayers of VMD.
Two experiments were conducted on 10 min datasets from the National Renewable Energy Laboratory (NREL).
The performances of the proposed model were compared with various representative models.
The experimental results indicate that the proposed model has better accuracy than the comparison models.
Among the thirteen models, the proposed VMD-BBA-EnsOSELM model can obtain the best prediction accuracy, and the mean absolute percent error (MAPE) is always less than 0.09.
