Presentation Description: A pressing question in the wind industry remains - how can we reduce the cost of wind energy and de-risk future projects? The Consortium for Advancing Remote Sensing (CFARS), an industry consortium comprised of a diverse group of stakeholders, launched to answer this cardinal question by striving to accelerate the use of remote sensing devices (RSDs) during various stages of wind resource assessment.
The CFARS RSD Site Suitability Subgroup seeks to provide data-driven answers to key RSD site suitability science questions and support the development of pragmatic solutions to hurdles that hinder the acceptance of RSD use for site suitability assessment; focusing on turbulence intensity (TI) measurements first. While RSD TI measurements offer several advantages compared to cup anemometers (e.g., higher height wind measurement range, higher ROI, mobile systems, etc.), given fundamental differences between the sensors’ wind measurement techniques, bias in TI measurements often exist.
The CFARS Subgroup established a series of benchmarking tests that targeted the following research questions; 1) What is intrinsic cup to redundant-height cup TI measurement error?, 2) How do corrected RSD TI measurements, using various methods, compare to intrinsic cup-to-cup TI error?, 3) How does TI measurement error impact turbine site suitability assessment decisions?
This work examines the final results of this industry-wide initiative compiled by the distribution of an opensource python tool, evaluating based on the foundational premise that inherent TI measurement error from cup anemometry on the same tower at the same height could also be considered RSD TI correction methods’ de facto acceptance threshold for error.
Methodology: We will present graphical visualizations summarizing the most compelling results of this study.
