The general objective of the Task 32 is to identify and mitigate barriers to the use of lidar for following wind energy applications:
- Site Assessment,
- Power Performance,
- Loads and Control,
- and Complex Flow.
These four applications will be addressed individually, since they are on different technology readiness levels. While for the more traditional applications Site Assessment and Power Performance the difficulties remain more in the implementation, the challanges for new applications such as Loads and Control and Complex Flow are more related to research.
More specific details related to each application area can be found below.
Additional objectives are:
- Provide an international open platform for regular and continuous exchange of experience and progress from individual research activities and existing measurement projects on the performance of lidar devices and associated measurement techniques.
- Interconnect and leverage experience from several international research projects.
- Identify areas for further research and development as well as standardization needs.
- Continue to collect and summarize competences gained in IEA Recommended Practices and Expert Reports.
• Revise IEA Recommended Practices for ground-based remote sensing
• Revise IEA Recommended Practices for floating lidar systems
• Explore ways to improve lidar systems regarding cost, reliability and accuracy
Loads & Control
• Explore the economic benefits of lidar-assisted control.
• 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.
• Understand the needs of measurements of complex flow in wind energy and describe the limitations of lidar systems.
• Find metrics to compare flow simulations and lidar field measurements.
Three 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. It is expected, that the extension will further strengthen the international exchange of knowledge, experience, and ideas and will further foster the use of lidars in wind energy.
