This study analyzes the impact of wind turbine rotor blade flexibility on the aerodynamic loading of the blades and the consequential wind characteristics in the near wake of the turbine. It is shown that gravitation leads to rotational periodic fluctuations of blade loading, which directly impacts the trajectory of the blade tip vortex at different rotor blade positions while also resulting in a non-uniform wind velocity deficit in the wake of the wind turbine.

This study examines wind vane measurements of commercial wind turbines and their impact on yaw control. The authors discovered that rotor interference can cause an overestimation of wind vane measurements, leading to overcorrection of the yaw controller. A correction function that improves the yaw behaviour is presented and validated in free-field experiments on a commercial wind turbine. This work provides new insights into wind direction measurements and suggests ways to optimize yaw control.

The current turbulent wind field models stated in the IEC 61400-1 standard underestimate the probability of extreme changes in wind velocity. This underestimation can lead to the false calculation of extreme and fatigue loads on the turbine. In this work, we are trying to apply a random time-mapping technique to one of the standard turbulence models to adapt to such extreme changes. The turbulent fields generated are compared with a standard wind field to show the effects of this new mapping.

Within the framework of the fourth phase of the International Energy Agency's (IEA) Wind Task 29, a large comparison exercise between measurements and aeroelastic simulations has been carried out. Results were obtained from more than 19 simulation tools of various fidelity, originating from 12 institutes and compared to state-of-the-art field measurements. The result is a unique insight into the current status and accuracy of rotor aerodynamic modeling.

This letter clarifies the key parameters governing the wake recovery of a floating wind turbine undergoing surge motions. An increased wake recovery is extremely beneficial since it can significantly increase the power output of wind farms. A dedicated wind-tunnel campaign covering fast platform motions well beyond current literature is presented. This enabled a full characterisation of the wake recovery and the discovery of a previously unreported wake mixing phenomenon.

For modern wind turbines, the effects of inflow wind fluctuations on loads are becoming increasingly critical. Based on field measurements and simulations, we identify “bump” events responsible for high damage equivalent loads. In this article, we introduce a new characteristic of a wind field: the virtual center of wind pressure, which highly correlates to the identified load events observed in the operational measured data.

Short summary
Among wind energy research, wind turbines with more than one rotor have recently gained a lot of attraction. Apart from promised lower maintenance- or construction costs, an increase in power generation per area, a better control over their wake (wind shadow/turbulence from turbines) makes these turbines highly attractive for large scale usage. This study shows experimentally, how the wake in a dual rotor can be steered and why this is highly promising for increasing windfarm efficiencies.

Most human activity happens in the layer of the atmosphere which extends a few hundred meters to a couple of kilometers above the surface of the Earth. The flow in this layer is turbulent. Turbulence impacts wind power production and turbine lifespan. Optimizing wind turbine performance requires understanding how turbulence affects both wind turbine efficiency and reliability. This paper points to gaps in our knowledge that need to be addressed to effectively utilize wind resources.

Two major aircraft measurement campaigns above the North Sea provide insights into modifications of the wind field and sea surface induced by wind farms: The aircraft performed transects at hub height upstream and downstream of wind farm clusters, and identified different effects, e.g., how long it takes for the wind speed to recover after the wind farm, how changes across the coastline interact with wind energy, and if wind farms are well represented in numerical simulations.

Short summary
Various simulation tools exist to provide load forecasts in the wind energy field (engineering models and numerical simulations). A newly introduced concept is the center of wind pressure, a quantity extracted from a wind field. In previous works, similar behaviour, then the main shaft bending moments, was shown. However, a clear relationship is missing. In this work, this gap is filled through the introduction of a calibration parameter.

Short summary
Increased sizes of modern turbines require extended descriptions of the atmospheric wind and its correlation to loads. Here, a surrogate stochastic method for estimating the bending moments at the main shaft is proposed. Based on the center of wind pressure dynamics, an advantage is the possibility of stochastically reconstructing large amounts of load data. Atmospheric measurements and modeled data demonstrate the validity of this method.

Short summary
Unexpected load events measured on operating wind turbines are not accurately predicted by numerical simulations. We introduce the periods of constant wind speed as a possible cause of such events. We measure and characterize their statistics from atmospheric data. Further comparisons to standard modelled data and experimental turbulence data suggest that such events are not intrinsic to small-scale turbulence and are not accurately described by current standard wind models.

Short summary
Wind turbines are often clustered within wind farms. A consequence is that some wind turbines may be exposed to the wakes of other turbines, which reduces their lifetime due to the wake turbulence. Knowledge of the wake is thus important, and we carried out wind tunnel experiments to investigate the wakes. We show how models that describe wakes of bluff bodies can help to improve the understanding of wind turbine wakes and wind turbine wake models, particularly by including a virtual origin.

Short summary
High-fidelity fluid–structure-coupled simulations of the IEA 15 MW rotor under storm and yaw misalignment shows that certain misalignments trigger strong edgewise vibrations. Growth surges when effective power turns positive near −35° and fades near −43° yaw. Single-blade analysis finds lock-in at −37° with large tip motion and stability at −60° due to off-resonant Strouhal shedding. It is concluded that aeroelastic response is inflow specific, and operational mitigation strategies are needed.
