Optimization of wind farm performancebased on yaw angle control (2014)
Presentation / Conference Contribution
Bastankhah, M., Dios Romero, I., & Porte-Agel, F. (2014, June). Optimization of wind farm performancebased on yaw angle control. Paper presented at 21st Symposium on Boundary Layers and Turbulence (BLT), Leeds, UK

Inside wind farms, the wakes of upwind turbines result in a significant reduction in power production. Yawing upwind turbines can be used to deflect the wakes away from turbines. Even though this reduces the power production of upwind turbines, it ca... Read More about Optimization of wind farm performancebased on yaw angle control.

Effects of positive versus negative yaw angles on wind-turbine performance: an application of BEM theory (2014)
Presentation / Conference Contribution
Bastankhah, M., & Porte-Agel, F. (2014, April). Effects of positive versus negative yaw angles on wind-turbine performance: an application of BEM theory. Poster presented at European Geosciences Union (EGU), Vienna, Austria

Wind-turbine wakes have negative effects on wind-farm performance. They are associated with: (a) the velocity deficit, which reduces the generated power of downwind turbines; and (b) the turbulence level, which increases the fatigue loads on downwind...

A new analytical model for wind-turbine wakes (2014)
Journal Article
Bastankhah, M., & Porté-Agel, F. (2014). A new analytical model for wind-turbine wakes. Renewable Energy, 70, 116-123. https://doi.org/10.1016/j.renene.2014.01.002

A new analytical wake model is proposed and validated to predict the wind velocity distribution downwind of a wind turbine. The model is derived by applying conservation of mass and momentum and assuming a Gaussian distribution for the velocity de fi... Read More about A new analytical model for wind-turbine wakes.
