Active Yaw Control

Active Yaw Control for Increased Windfarm Production

The wakes (volumes of slower and turbulent wind) behind the turbines in a wind farm result in production losses for the downstream turbines by up to 20%. This effect can be mitigated using an active yaw control, by deflecting the wake propagation away from the other turbines, hence increasing the total production.

Background:

  • Wakes behind turbines propagate for long distances, especially in off-shore conditions.
  • Wake effects impair the performance of downstream turbines by up to 20%.
  • This also causes additional structural fatigue due to velocity fluctuations within wakes.

 

Research Objectives:

Develop an active yaw control algorithm for the entire wind farm that can:

  • Adjust the yaw angle of each turbine individually
  • Estimate and track the wake propagation
  • Deviate the wakes away from the downstream turbines
  • Improve the total wind farm production

The method will be developed and evaluated using Fast.FARM

  • Novel open-source wind farm simulation software
  • Solves aero-servo-elastic dynamics for each turbine
  • Released in 2021 by NREL
