Abstract

Wind power is one of the most attractive forms of electricity from the viewpoints of cost efficiency and environmental protection. However, the instability of wind power has a serious impact on a grid system. Reliable wind power forecasting will help to utilize storage systems and backup generators effectively for mitigating the instability. This paper proposes a feature extraction procedure for numerical weather prediction (NWP) data based on the three-dimensional convolutional neural networks (3DCNNs). An advantage of 3D-CNNs is to automatically extract the spatio-temporal features from NWP data focusing on the targeted wind farm. Feature extraction based on 3D-CNNs was applied to real-world datasets; the results show significant performance in comparison to several benchmark approaches, and also show that the proposed extraction scheme based on 3DCNNs achieves to derive intrinsic features for prediction of wind power generation from NWP data.
