Objectives

Our Objectives

Wind lidar allows lots of information about wind characteristics to be collected at wind energy development sites before they are built, during their construction and commissioning, and during operations. Designing, selecting, installing and operating such devices effectively, and making appropriate decisions from the data they provide, requires new understanding and approaches compared to other sources of data but also brings new possibilities.

Task 32 exists to enable exchange of experience and ideas between the many different stakeholders that are involved with the use of wind lidar by the wind industry, helping everyone make the best use of wind lidar.

Application Areas

The general objective of Task 32 is to identify and mitigate barriers to the use of lidar for four wind energy applications, including site assessment, power performance, loads and control, and complex flow.

These four applications are addressed individually as they are on different technology readiness levels. Specific objectives for the application areas are:

Site Assessment

  • Revise the IEA Recommended Practices #15 for ground-based remote sensing for wind resource assessment and the IEA Recommended Practices #18 for floating lidar systems.
  • Explore ways to improve lidar systems regarding cost, reliability and accuracy.

Power Performance

  • Identify gaps in standards and transferability that may prevent widespread adoption.
  • Explore if and how new standards for the use of ground-based lidar systems needs to be adapted for the use of nacelle or spinner-based or floating lidar systems.

Loads and Control

  • Explore the benefits of lidar-assisted control for the cost of wind energy.
  • Give recommendations on how to improve lidar systems for control application.
  • Initiate guidelines on how to use lidar in the load verification process of wind turbines.

Complex Flow

  • Understand the needs of measurements of complex flow in wind energy and describe the limitations of lidar systems to provide recommendations for adjustments.
  • Find metrics to compare flow simulations and lidar field measurements.

Workshops will be held for each of the applications and reports will summarize how the objectives have been accomplished, including the revision of two IEA Recommended Practices.
