Schmidt, H.S. (author), Leschinger, Valentin (author), Müller, Florian J.Y. (author), de Vries, G. (author), Renes, Reint Jan (author), Schmehl, R. (author), Hübner, Gundula (author)Airborne wind energy (AWE) is an emerging renewable energy technology that uses kites to harvest winds at higher altitudes than wind turbines. Understanding how residents experience a local AWE system (AWES) is important as the technology approaches commercialization. Such knowledge can help adjust the design and deployment of an AWES to fit...journal article 2024

Boatto, Umberto (author), Bonnet, Paul A. (author), Avallone, F. (author), Ragni, D. (author)Blade Element Momentum Theory (BEMT) -based approaches provide 15%–20% inaccurate load predictions under uniform steady inflow. Inaccuracies were related to unclear aerodynamic mechanisms causing the Prandtl Tip-Root Loss (TRL) correction to fail at high Tip-Speed Ratio (TSR) and the ambiguous drag coefficient treatment under Stall Delay (SD)...journal article 2023

Sykes, Victoria (author), Collu, Maurizio (author), Coraddu, A. (author)The deployment of offshore wind in the UK has seen a rapid increase in the past decade and will continue to increase with the securement of the recent Scotwind sites. Floating platforms will be utilised for 60% of these new sites, creating opportunities to try new platform typologies and further solidify the validity of existing concepts....review 2023

Sykes, V. (author), Collu, M. (author), Coraddu, A. (author)The development and deployment of offshore wind farms in the last decade have seen a dramatic increase, now totalling 743 GW globally (Global Wind Energy Council, 2022). This rapid increase is expected to further continue now with the potential to explore deeper sites with the adoption of floating offshore platforms. Proof of this growth has...review 2023

Luesutthiviboon, S. (author)Nowadays, large wind turbines are installed and operated close to densely populated areas due to the growing need for renewable energy. Noise constraints are hampering this development. The most relevant wind turbine noise source is the so-called Turbulent Boundary Layer Trailing-Edge (TBL–TE) noise. Many passive TBL–TE noise reduction...doctoral thesis 2022

Mordasov, Dmitrij (author)With the growing global utilisation of wind energy, lowering of its levelised cost of energy is pursued. This effort is hindered by wind turbine wakes and their detrimental effects on wind farm profitability. Most currently researched wake mitigation methods are based on wind farm system-level interventions, and there is a research gap on...master thesis 2022

Chen, Z. (author), Lin, Zhongwei (author), Zhai, Xiaoya (author), Liu, Jizhen (author)A challenging topic arising in dynamic wind turbine wake is modeling, especially the low-order approximation. The central problem is the fact that it has high-dimensional and nonlinear wake characteristics. In this paper, a Koopman-linear flow estimator is designed according to the Koopman operator theory. Different from the conventional flow...journal article 2022

Liao, D.L. (author), Zhu, Shun Peng (author), Correia, J.H.G. (author), De Jesus, Abílio M.P. (author), Veljkovic, M. (author), Berto, Filippo (author)Wind, as a sustainable and affordable energy source, represents a strong alternative to traditional energy sources. However, wind power is only one of the options, together with other renewable energy sources. Consequently, the core concerns for wind turbine manufacturers and operators are to increase its reliability and decrease costs,...journal article 2022

Mathew, Joan (author)With a growing demand for longer blades in the wind turbine industry for higher rated power per turbine, a structurally sound blade-root connection is of commercial importance. Bushing connections have been a commercially favoured design in the past few years, replacing the commonly used T-bolt connection as the joining method of choice. The new...master thesis 2021

Gooijaers, Leo (author)To be able to increase the safety and efficiency of automated wind turbine inspection a robust solution is needed that takes into account wind during trajectory planning. This paper presents such a solution in the form of an algorithm, which uses Dijkstra’s algorithm as a basis for optimisation. To allow for online replanning the horizontal and...master thesis 2021

Ahmad, Z. (author), Rueda, José L. (author), Veerakumar, Nidarshan (author), Rakhshani, E. (author), Palensky, P. (author), van der Meijden, M.A.M.M. (author)A task for new power generation technologies, interfaced to the electrical grid by power electronic converters, is to stiffen the rate of change of frequency (RoCoF) at the initial few milliseconds (ms) after any variation of active power balance. This task is defined in this article as fast active power regulation (FAPR), a generic definition...review 2020

Bastiaanssen, Piet (author)The offshore wind energy industry has been developing rapidly due to the increasing demand for renewable energy. As a result, offshore wind turbines are increasing in mass and height and are installed at larger water depths and further away from shore. A floating vessel is not limited by water depth and soil conditions, but is sensitive to wave...master thesis 2020

van Beek, Maarten (author)Wind farms experience significant efficiency losses due to the aerodynamic interaction between turbines. A possible control technique to reduce these losses to a minimum is yaw-based wake steering. This thesis investigates the feasibility of this technique by calibrating a surrogate model called the FLOw Redirection and Induction in Steady-state...master thesis 2020

Liu, Dong (author), Song, Xiaowei (author), Wang, X. (author)In recent years, permanent magnet superconducting (PMSC) generators have become a candidate for applying superconducting (SC) generators in large direct-drive wind turbines. This configuration keeps the SC armature winding and its cooling system stationary and eliminates rotational cooling couplings. However, the low excitation by permanent...conference paper 2020
