Performance Test of a 3MW Wind Turbine – Effects of Shear and Turbulence
TLDR
In this article, a full wind turbine performance test has been performed on a 3MW onshore wind turbine in a coastal location in Norway utilizing a Windcube v2 lidar, and results show how turbulence, shear and veer influence the power production and the power curve derived from hub height and equivalent wind speed respectively.About:

Do we really need rotor equivalent wind speed
TL;DR: In this article, the relevance of the rotor equivalent wind speed method depends on turbine dimensions and wind shear regime, and it is shown that the relevance depends on the ratio of rotor diameter and hub height.

TL;DR: In this article, the importance of other variables in an analysis of power curves for three 2.5 MW wind turbines was discovered, and the sensitivity of the observed power curves was largely due to two factors: (1) an actual sensitivity to turbulence in determining the power curve and (2) the deviation of the disk-averaged velocity from the hub-height velocity under low turbulence conditions that were most prevalent at the site.
