A review of wind speed probability distributions used in wind energy analysis: Case studies in the Canary Islands
TL;DR: In this paper, a review of the use of the probability density function (PDF) of wind speed is carried out for a wide collection of models, and the methods that have been used to estimate the parameters on which these models depend are reviewed and the degree of complexity of the estimation is analyzed in function of the model selected.

Large-Eddy Simulation of Wind-Turbine Wakes: Evaluation of Turbine Parametrisations
Yu Ting Wu,Fernando Porté-Agel +1 more
TL;DR: In this paper, a tuning-free Lagrangian scale-dependent dynamic subgrid-scale (SGS) model is used for the parametrisation of the SGS stresses, and the turbine-induced forces (e.g., thrust, lift and drag) are parametrised using two models: (a) the standard actuator-disk model (ADM-NR), which calculates only the thrust force and distributes it uniformly over the rotor area; and (b) the actuatordisk model with rotation, which uses the blade-element theory to

Wind plant power optimization through yaw control using a parametric model for wake effects—a CFD simulation study
P.M.O. Gebraad,F. W. Teeuwisse,J.W. van Wingerden,Paul Fleming,Shalom D. Ruben,Jason R. Marden,Lucy Y. Pao +6 more
TL;DR: In this article, a wind plant control strategy that optimizes the yaw settings of wind turbines for improved energy production of the whole wind plant by taking into account wake effects is presented.

Potential order-of-magnitude enhancement of wind farm power density via counter-rotating vertical-axis wind turbine arrays
TL;DR: In this article, the authors investigated the use of counter-rotating vertical-axis wind turbines (VAWTs) in order to achieve higher power output per unit land area than existing wind farms consisting of HAWTs.
