Giyanani, A.H. (author), Bierbooms, W.A.A.M. (author), Van Bussel, G.J.W. (author)Wind turbine design, control strategies often assume Taylor’s frozen turbulence where the fluctuating part of the wind is assumed to be constant. In practise, the wind turbine faces higher turbulence in case of gusts and lower turbulence in some cases. With Lidar technology, the frozen turbulence assumption could be avoided and the evolution of...conference paper 2015

Bierbooms, W.A.A.M. (author), Peeringa, J. (author)Up to now just deterministic gust shapes are specified in standards; e.g. the Extreme Operating Gust (IEC) is given by a Mexican hat like shape. In this paper gust shapes will be determined by application of so-called constrained stochastic simulation. This method specifies how to efficiently generate time series around some specific event (e.g....conference paper 2009

Bos, R. (author), Bierbooms, W.A.A.M. (author), Van Bussel, G.J.W. (author)An important problem that arises during the design of wind turbines is estimating extreme loads with sufficient accuracy. This is especially difficult during iterative design phases when computational resources are scarce. Over the years, many methods have been proposed to extrapolate extreme load distributions from relatively short time series...conference paper 2015

Giyanani, A.H. (author), Bierbooms, W.A.A.M. (author), Van Bussel, G.J.W. (author)Remote sensing of the atmospheric variables with the use of LiDAR is a relatively new technique for wind resource assessment and oncoming wind prediction in wind energy. The validation of LiDAR measurements and comparisons with other sensing elements thus, is of high importance for further applications of the data. A measurement campaign with...conference paper 2014

Bierbooms, W.A.A.M. (author)The probabilistic method commonly applied to arrive at the ultimate loading is as follows: for several different mean wind speeds load simulations are performed. For each mean wind speed a conditional distribution can be fitted to the load maxima for that particular wind speed. The overall distribution of the load response is obtained by a...conference paper 2010

Bos, R. (author), Bierbooms, W. (author), Van Bussel, G. (author)With the trend of moving towards 10-20MW turbines, rotor diameters are growing beyond the size of the largest turbulent structures in the atmospheric boundary layer. As a consequence, the fully uniform transients that are commonly used to predict extreme gust loads are losing their connection to reality and may lead to gross over dimensioning....journal article 2014

Holtslag, M.C. (author), Bierbooms, W.A.A.M. (author), Van Bussel, G.J.W. (author)Atmospheric stability strongly influences wind shear and thus has to be considered when performing load calculations for wind turbine design. Numerous methods exist however for obtaining stability in terms of the Obukhov length L as well as for correcting the logarithmic wind profile. It is therefore questioned to what extend the choice of...journal article 2014

Holtslag, M.C. (author), Bierbooms, W.A.A.M. (author), Van Bussel, G.J.W. (author)In this paper the dependence of wind turbine fatigue loads on atmospheric stability is assessed. It is shown that fatigue loads depend strongly on stability, and highest loads occur for very unstable conditions. For a given hub height wind speed one can dene an equivalent atmospheric stability that corresponds to the same cumulative loads as if...journal article 2014

Bierbooms, W.A.A.M. (author)The method of so-called constrained stochastic simulation is introduced. This method specifies how to efficiently generate time series around some specific event in a normal process. All events which can be expressed by means of a linear condition (constraint) can be dealt with. Two examples are given in the paper: the generation of stochastic...journal article 2005

Alblas, L. (author), Bierbooms, W. (author), Veldkamp, D. (author)Atmospheric stability is known to influence wind farm power output, by affecting power losses due to wakes. This research tries to answer what atmospheric stability does to the power production and how conventional simulations using the Jensen wake model compare and can be improved. Data is used from two offshore wind farms, Egmond aan Zee (OWEZ...journal article 2014

Ranka, Preeti (author), Valldecabres, Laura (author), Schafhirt, Sebastian (author), Bierbooms, W.A.A.M. (author)Ramp events, i.e., significant changes in wind speed in a short time period, have become critically important to end-users. However, only a few studies address their impact on wind turbine loads. To the best of the authors' knowledge, these results have not yet been validated with measurements. Therefore, this paper aims to investigate the...journal article 2022
