Application of Deep Learning Models in Wind Farm Power Output Forecasting
Abstract
Wind energy stands out as one of the fastest-growing clean energy sources worldwide, driven by global commitments to decarbonization, enhanced energy security, and sustainable development. Accurate forecasting of wind farm power output thus becomes a key prerequisite for better harnessing renewables and optimizing grid management. The non-stationary, stochastic, and multi-scale nature of wind speed and direction poses serious limitations for traditional forecasting models. In recent years, the rise of deep learning has sparked a major revolution in time series prediction, particularly outperforming classical statistical and machine learning methods in wind energy forecasting. This paper analyzes recent research on wind power prediction, focusing on deep learning architectures, spatial-temporal models, physics-informed approaches, and hybrid designs. It also reviews data sources such as Supervisory Control And Data Acquisition (SCADA), Meteorological Data (Meteo), Numerical Weather Prediction (NWP), remote sensing, and multi-source structures. Beyond offering a conceptual classification, quantitative and qualitative comparisons of methods, analysis of research challenges, computational complexity reviews, and identification of knowledge gaps, the study outlines future research directions. Findings reveal that attention-based models excel at capturing inter-turbine relationships, while decomposition-driven hybrids like Wavelet–LSTM, VMD–BiLSTM, and EMD–GRU deliver the highest accuracy and stability. Persistent challenges include data heterogeneity, spatial-temporal wind variations, the need for probabilistic forecasts, lack of interpretability, and demand for lightweight architectures.
