Rodriguez, Mario (author)
Using renewable energy to power a Mars habitat is a technological challenge because resources such as solar and wind are significantly weaker than on Earth. This work investigates the feasibility of using airborne wind energy (AWE) systems in combination with solar photovoltaic (PV) modules to power a Mars habitat. The Luchsinger model and the...

To expand the economic operating range of offshore wind farms, less common but innovative solutions regarding support structures should be considered. To increase the popularity of gravity-based foundations (GBF) within the offshore wind industry, a better understanding of the hydrodynamics on GBFs, as well as an improved insight in the optimal...

Offshore wind energy is expected to play a major role in the upcoming energy transition. For long distances to shore, it is preferable to connect the wind farms to land by means of High-Voltage DC (HVDC) cables to reduce losses and costs. This currently poses challenges, as wind turbine generators produce variable-frequency low-voltage AC power,...

Cardiff Aleu, Joana (author)
The design of wind turbines is an iterative process in which load calculations and system performance analyses are done under various environmental conditions. Due to the complexity of wind turbine systems, fully coupled aero-hydro-servo-elastic codes are indispensable to represent the nonlinear behaviour of the system. However, nonlinear codes...

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...

Kerckhoffs, Hugo (author)
In recent years, the demand for renewable energy has increased significantly because of its lower environmental impact than conventional energy technologies. As a result, wind power is one of the most important renewable energy sources. As land-based turbines have reached their maximum potential, recent market trends are moving into deeper waters...

The offshore wind market is a fast growing market. Currently, 3 GW of offshore wind are installed in The Netherlands. However, the ambitions of the Dutch government are to have 30 GW offshore wind installed by 2030. The current installed offshore wind capacity of Europe is 28 GW. The EU ambitions are to install 60 GW by 2030 and to install 300...

Thermal ice pressure is one of the eight ice loads to consider for the support structure design of bottom-fixed offshore wind turbines defined by international standard IEC 61400031. Temperature changes in ice drive its deformation and cause structures restricting expansion to experience loading. The effective coefficient of thermal expansion ...

Computational Fluid Dynamics based on RANS models remain the standard but suffer from high errors in complex flows. In particular, turbulent kinetic energy is over-produced in high strain rate regions, such as the near wake of wind turbine flows. Data-driven turbulence modelling methods aim to derive novel turbulence models with lower...

de Boer, Emiel (author)
To meet current renewable energy demands, there is a major increase in global wind power capacity. Wind turbines are commonly clustered in wind farms. When operating, wind turbines extract energy from the wind, creating a region characterized by a low velocity, called the wake. The wake negatively impacts the power production of downstream wind...

The report summarises the development of a frequency domain Multi-Unit Floating Platform (MUFP) model and a parametric design optimization using the model. The model returns the response statistics of a MUFP due to environmental wind and wave loading using input variables of column separation, column diameter and draft. The model is developed...

An investigation into AC superconducting coils is performed with a permanent magnet generator for a wind power turbine of 15 MW. Two reference models are sized: on the one hand, a DTU and NREL 15 MW wind turbine model is taken as a reference to set the mechanical speed according to the output power and the mechanical constraints of the blades;...

In order to reduce the levelised cost of energy, the rotors of wind turbines are increasing in size. To increase the energy yield, wind turbine rotors need to have an innovative tip design; such as winglets. Winglets are used widely in aircraft design; however, they remain mostly absent in state-of-the-art wind turbine design. The low-fidelity...

Simulations of a spar-type floating wind turbine supporting the DTU 10 MW reference turbine under fitted atmospheric conditions are performed. Atmospheric conditions are modelled using the turbulent models recommended by the IEC: the Mann model and the IEC Kaimal and exponential coherence model. Model parameters are fitted to measurements at the...

A key challenge in the Airborne Wind Energy industry is the minimisation of the time and energy required for the transfer and return phases inherent to the power cycles of ground-generator-based kite power systems. This thesis contributes to solving this problem by exploring the use of bleed air spoilers during the return phase in terms of their...

Gertsen, Thomas (author)
Wind turbines are operating in harsh environmental conditions, especially offshore. An implication of these conditions, caused by the impact of precipitation, is the development of leading edge erosion (LEE). This leads to degraded blade surfaces that result in lower aerodynamic performance. Leading edge erosion is researched in many ways but...

The goal of this thesis is to investigate the feasibility of optimizing the mooring line characteristics of a semi-taut (chain – polyester – chain) mooring system in combination with drag embedded anchors for a 12 MW wind turbine supported by a semi-submersible in deep water, based on static analysis of the Ultimate Limit State (ULS) condition....

Floating offshore wind turbines can only withstand a limited amount of (heave) motions before the equipment fails. In order to reduce the heave motion, the DeepCwind floater for offshore floating wind turbines makes use of heave plates. This semi-submersible floater consists of three cylindrical columns with a heave plate attached to the bottom...
