Workshop 3:

Lidar measurements for wake assessment and comparison with wake models

October 4, 2016

Workshop leaders Task 31: Javier Sanz Rodrigo (CENER, Spain). Task 32: Davide Trabucchi (ForWind - University of Oldenburg, Germany)

Venue: Technical University of Munich, Munich, Germany

Meeting Goals

Some possibilities to measured complex flows such as wakes with lidars have been explored recently with positive results. These studies suggest that lidar measurement could be included in the verification and validation process of wake models. These models are important for wind turbine and wind farm design as well as wind farm control. However, the use of the lidar technology in this field is hindered by different knowledge of lidar measurement limitations and wake models and limited access to data.

This workshop addresses these challenges by bringing together different IEA Wind Tasks. Task 31 aims to verify, validate, and quantify the uncertainties of the most widely used models on the basis of experimental datasets. Task 32 deals with wind lidar measurements in order to identify and mitigate barriers to the use of lidar technology in wind energy applications

The workshop discussed the following questions:

  1. What has been done so far?
  2. What are the objectives of lidar wake measurements?
  3. How can we collaborate with existing measurement data?
  4. How can we collaborate in future?
