To address the challenges of achieving continuous parameterization and the limited application of graph neural networks in existing deep learning-based wind farm wake modeling
this study proposes a Graph Transformer-based wind farm wake model. Firstly
a large-scale wake dataset is constructed
encompassing diverse environmental and control parameters. A coordinate-based sampling and distance-priority strategy is employed to design the wake graph structure
generating node feature matrices that include wake field coordinates
environmental
and control parameters for neural network training. Subsequently
a Graph Transformer-based wake modeling algorithm
i.e.
GT-Wake
is developed. In which the self-attention mechanism is leveraged to dynamically adjust the weight allocation of neighboring nodes in the graph structure
thereby enhancing the model’s ability to capture both local and global wake characteristics. Experimental results demonstrate that compared to MLP
CNN
and GraphSAGE
GT-Wake significantly improves modeling accuracy and achieves a favorable balance between generalization capability and computational efficiency.
