Summary

A new domain adaptation approach significantly improves cross-farm power curve modeling for wind energy site-planning. This method addresses the challenge of transferring power curve models, trained on data from an operating wind farm, to an undeveloped farm. Traditionally, such transfers rely on distance, layout, or terrain characteristics. The proposed technique, however, uses domain adaptation to establish a reliable similarity metric between the temporal environmental variates and spatial terrain variables of the source and target farms. Empirical results demonstrate that this domain-adapted power curve consistently outperforms competing approaches, offering more accurate site-planning power predictions. This advancement is critical for evaluating turbine performance, quantifying upgrades, and supporting strategic site-planning decisions in the wind energy industry.

Key takeaway

For wind energy engineers and site planners evaluating new farm developments, adopting domain-adapted power curve models can significantly enhance prediction accuracy. You should consider integrating this transfer learning approach, which utilizes temporal environmental and spatial terrain variables, to improve site-planning decisions, turbine performance evaluations, and upgrade quantifications. This method offers a more robust alternative to traditional distance or terrain-based transfer techniques, leading to more reliable power forecasts for undeveloped sites.

Key insights

Domain adaptation offers a more reliable approach for transferring wind turbine power curve models across different wind farm sites.

Principles

• Cross-farm power curve transfer benefits from domain adaptation.
• Domain similarity can be based on temporal and spatial variables.

Method
