Turbulence distortion matters in predicting inflow turbulence noise of future wind turbines
This study examines the role of turbulence distortion in predicting inflow turbulence (IT) noise generation from large wind turbines via Amiet's theory. Two subsequent distortion mechanisms are investigated: (i) the streamtube expansion in the rotor induction zone and (ii) the interaction with the…

Low-level jets' influence on the power conversion efficiency of offshore wind turbines
Low-level jets (LLJs) are local maxima in the vertical wind speed profile. They are frequently observed at heights of approximately 50–500 ma.s.l. in offshore regions. The influence of LLJs on the power conversion of the energy flux through the rotor-swept area and loads of wind turbines has not…

Optimizing the operation of energy islands with predictive nonlinear programming – a case study based on the Princess Elisabeth Energy Island
The concepts of energy islands or energy hubs have gained attention in Europe as a means to enhance offshore wind integration and regional energy systems. These islands can incorporate high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) transmission systems, battery…

Determining the ideal length of wind speed series for wind speed distribution and resource assessment
Accurate wind resource assessment depends on wind speed data that capture local wind conditions, which are crucial for energy yield estimates and site selection. While the International Electrotechnical Commission (IEC) recommends at least 1 year of data collection, this duration may be…

Bidirectional wakes over complex terrain using SCADA data and wake models
We investigate bidirectional wake effects between two wind turbines of the same type in a hill region in northern Japan using supervisory control and data acquisition (SCADA) data and validate the simulated wakes using 12 wake models. The extent to which complex terrain affects wake behavior has…

A wind turbine digital shadow for complex inflow conditions
We present a digital shadow Kalman filtering framework based on the direct linearization of a trusted multibody aeroservoelastic wind turbine model. In contrast to shadowing based on ad hoc modeling approaches, reusing validated industrial or research-grade models reduces the development effort…

How accurately do engineering methods capture floating wind turbine performance and wake? A critical perspective using multi-fidelity simulations
Despite an increasing number of experimental and numerical studies, the influence of platform motion on wake dynamics (wake recovery and turbulence production) in floating offshore wind turbines is still an open research question. In particular, efforts are being made to understand the accuracy of…

Wind turbine wake dynamics subjected to atmospheric gravity waves: a measurement-driven large-eddy simulation study
Atmospheric gravity waves (AGWs) are large-scale wave-like flow structures commonly generated when atmospheric flows are vertically perturbed by topographical features or meteorological phenomena. These transient phenomena can significantly affect wind turbine outputs and loads; however, their…

Design of fatigue-based specifications for the design of controllers in wind turbines
Pitch controllers are critical components in wind turbines, and their design typically involves lengthy iterative processes of tuning and simulation-based validation. Using well-defined control specifications, rigorously linked to engineering requirements, can significantly reduce the effort needed…

Numerical analysis of dynamic wind turbine airfoil characteristics in transonic flow
Modern large wind turbine rotors can encounter airflow at inflow Mach numbers of around 0.3 and Reynolds numbers of the order of 10 million at the blade tip. Our previous study (Vitulano et al., 2025) showed that for these operational conditions, the incompressibility assumption is violated, and…

Impact of atmospheric turbulence on performance and loads of wind turbines: knowledge gaps and research challenges
Wind energy harvesting from the atmosphere takes place in the atmospheric boundary layer. The boundary layer shear and buoyancy create three-dimensional turbulent eddies spanning a range of scales that form a continuous forward cascade of kinetic energy to the smallest scales of motion where energy…
