Details on the specifications of turbines, farms, and the characteristics of the inflow in each case are provided in Table I in our PRX paper. Structures of the datasets: The datasets include efficiency values for all turbines in each case for different incoming wind directions, with a step of 2 degrees. The turbine efficiency is the ratio of its power to the extracted power if it were standing upstream. Turbine-level data for Cases 1-4 contain 28,800 data points. Case 5 adds 14,400 data points, and Cases 6 and 7 add 17,280 data points to the dataset (60,480 data points in total). The datasets include 11 different features of data for each turbine: - Turbine's ID- Turbine's x coordinate- Turbine's y coordinate- Turbine's rotor diameter- Turbine's hub height- Turbine's thrust coefficient- Turbine's power coefficient- Inflow velocity at the hub height- Inflow turbulence level at the hub height- Wind direction- Turbine's efficiency How to cite: To cite our datasets, please use the following Bibtex records:@article{PRXEnergy.2.013009, title = {Physics-Guided Machine Learning for Wind-Farm Power Prediction: Toward Interpretability and Generalizability}, author = {Zehtabiyan-Rezaie, Navid and Iosifidis, Alexandros and Abkar, Mahdi}, journal = {PRX Energy}, volume = {2}, issue = {1}, pages = {013009}, numpages = {17}, year = {2023}, month = {Mar}, publisher = {American Physical Society}, doi = {10.1103/PRXEnergy.2.013009}, url = {https://link.aps.org/doi/10.1103/PRXEnergy.2.013009}}
