IEA Wind Task 32+Task 37 Workshop 15:
Optimizing Wind Turbines with Lidar-Assisted Control using Systems Engineering
17th and 18th October 2019
Workshop leader: Task 32: Eric Simley (NREL), Task 37: Pietro Bortolotti (NREL)
Organization team: Katherine Dykes (DTU Wind Energy), Holger Fürst (SWE), David Schlipf (WETI), Andy Scholbrock (NREL)
Venue: University of Massachusetts Amherst, Amherst, MA, USA
Following the NAWEA/WindTech 2019 Conference
Background to the Workshop
The goal of IEA Wind Task 32 is to identify and mitigate barriers to the use of wind lidar for wind energy applications including site assessment, power performance testing, loads and control, and measurements in complex flow. Within the topic of loads and control, Task 32 has been active in mitigating barriers to the use of lidar-assisted wind turbine control.
The purpose of IEA Wind Task 37 is to coordinate international research activities to analyze wind power plants as holistic systems. Through the development of analysis tools and reference models, Task 37 advances systems engineering methods for reducing the levelized cost of energy of wind energy projects.
Lidar-assisted control (LAC) is effective at reducing structural loads on wind turbines, which has been demonstrated through simulation as well as field testing. However, it is difficult to determine the reduction in cost-of-energy that can be achieved through the use of LAC, especially because of the additional costs associated with integrating lidar hardware into the turbine design. Furthermore, LAC is often analyzed using existing turbine designs. Systems engineering presents an opportunity to directly include the use of LAC during the turbine design process to optimize the levelized cost-of-energy. The aim of this workshop is to combine the experience in lidar-assisted controller design and modeling from Task 32 with the knowledge of systems engineering analysis using reference wind turbine models from Task 37 to show how wind turbines can be optimized with LAC.
The primary objective of the workshop is to identify a process for determining the reduction in cost-of-energy made possible by LAC. This objective can be divided into the following steps:
- To identify models and simulation capabilities that need to be established to include LAC in the wind turbine optimization process
- To identify reference wind turbine models and controllers that can be used to quantify the benefits of LAC
- To propose a process for optimizing a reference wind turbine and baseline controller using LAC
- To discuss opportunities to further collaborate on the proposed wind turbine optimization research
The workshop is split into six main sessions:
- Educational Session: Understanding LAC and systems engineering
- Presentations on the benefits of LAC
- Discussion of models needed to include LAC in the wind turbine optimization process
- Presentations on wind turbine optimization using systems engineering
- Discussion of methods for optimizing wind turbines with LAC
- Development of a research plan for optimizing wind turbines with LAC
The outcome of the workshop will be
- An exchange of experience in wind turbine optimization with systems engineering and LAC
- Initiation of a working group to write a white paper containing a roadmap for including LAC in the optimization of the cost-of-energy of wind turbines
- Identification of opportunities to pursue further research on wind turbine optimization with LAC
- Wind turbine manufacturers
- Lidar manufacturers
