In this study we present the evolution of the Eolos’ original machine learning (ML) turbulence intensity (TI) correction model. In 2024, Eolos developed a ML model specifically designed to correct TI measurements for the FLS200 buoy, a widely used floating lidar system.
Floating LiDAR Systems (FLS) are essential for delivering cost-effective and high-quality wind data in the offshore wind industry. While the 10-minute average Horizontal Wind Speed (HWS) measured by FLS compares well with traditional cup or sonic anemometers, significant discrepancies arise when assessing Turbulence Intensity (TI).
In this work we introduce a supervised Machine Learning (ML) model to correct the Turbulence Intensity (TI) measured by Floating LiDAR Systems (FLS) in offshore environment. The model was developed using data from 46 EOLOS-FLS200 validation campaigns (≈4.6 years) carried out at three reference sites in the North Sea.
In this study a correction of the measured TI from floating lidars is applied for wind resource characterization. Two EOLOS FLS200, mounting a ZX300M continuous wave lidar, are currently measuring wind conditions in the New York bight as part of a wind resource assessment campaign by the New York State Energy Research and Development Authority (NYSERDA).
