Overall Objectives

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.

Expected Results

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.
