Ottenheym, Joris (author)The placement of wind turbines in wind farms is economically beneficial to the industry. Consequently, the wake generated by the upstream turbines introduces interactions with downstream turbines that significantly affect power generation. However, it is common practice to control the individual turbines to operate at their optimal settings and...master thesis 2023

Kerssemakers, Daan (author)To accelerate the growth of offshore wind power, its Levelised Cost Of Energy (LCOE) must be reduced. A means of reducing the LCOE of offshore wind power is by mitigating the adverse wake effect by employing Wind Farm Control (WFC) for power maximization. A recent WFC technology is the helix approach, which uses Individual Pitch Control (IPC) to...master thesis 2022

Pollack, Justin (author)Nowadays, machine learning (ML) methods rapidly evolve for their use in model-based control applications. Model-based control requires an accurate model description of the dynamical system to reassure the performance of the controller. Conventionally, this model description is retrieved from first-principles modelling which can be problematic if...master thesis 2022

Halvorsen, Stijn (author)Wind energy plays an essential role in the transition to a sustainable future and wind turbines allow us to utilize it. Wind turbines are often installed in close proximity to make the best use of the given space and to save costs. This also has the disadvantage that the turbines influence each other due to wakes. This is where wind farm control...master thesis 2022

Huang, Louis (author)The development of offshore wind technology has progressed rapidly since the first offshore wind farm came to birth in 1991. During the last three decades, offshore wind has become an economically attractive option of renewable energy source for many countries to fulfill their commitment to combat the climate crisis. However, an open challenge...master thesis 2022

Wen, Haoyue (author)To extract energy from wind, both Horizontal Axis Wind Turbine (HAWT)s and Vertical Axis Wind Turbine (VAWT)s are used. Different from the HAWT, the axis of rotation of the VAWT is perpendicular to the ground. This vertical design offers some unique advantages for the VAWT. For example, the generator of the VAWT is located on the ground, hence...master thesis 2022

Ramos Lourenço de Armada, Oyono (author)In the mission to slow down global warming, the replacement of fossil fuels by renewable energy resources is key. A tipping point in the adoption of renewable energy resources is notable, as they are becoming economically more viable. Offshore wind energy is considered essential in realizing the greenhouse gas emission reduction targets. However...master thesis 2022

van Hanswijk, Daniel (author)Growth of the population, industry and agriculture increases the demand for fresh water. However, with only a small portion of the water on earth being suitable for direct human use and consumption, this growth makes water scarcity an increasing problem. Seawater desalination is an effective method to counter such water stress. Reverse Osmosis ...master thesis 2021

van Vondelen, Mees (author)Offshore Wind Turbine (OWT) structural design can be optimized to reduce structural costs, thereby lowering wind energy costs. Increasing turbine size and further structural cost reduction require more advanced insights into the dynamic system. One practice of analysing these vibrating structures is called Operational Modal Analysis (OMA). OMA...master thesis 2021

Ruiterkamp, Gilian (author)In recent years wind turbines have become increasingly large to increase energy yield and cost-effectiveness. This has led to taller turbine towers, subjected to larger loads. As a result, Lagerwey turbines experience lateral tower vibrations at different resonance frequencies. These vibrations result in rotor speed measurement disturbances due...master thesis 2021

Schepers, Job (author)Due to an increase demand for renewable and sustainable forms of energy, the offshore wind industry is growing rapidly. To make wind energy more cost-effective, new wind turbines are becoming larger in size and are placed further offshore. This results in deeper waters, making the installation more difficult. The current methodology uses a jack...master thesis 2021

Abbas, Omar (author)Placing wind turbines together is economically advantageous. It helps in decreasing the use of land or sea space, impact on the landscape and the cost of installation and maintenance. However, placing turbines together has a downside: the aerodynamics interaction caused by the wakes can negatively influence the total electrical power production...master thesis 2021

Seco Rodrigues, Nuno António (author)Systems and Control deals with modelling and control design of many different types of systems with different behaviour and characteristics. Often times it is challenging to build mathematical models to describe the system dynamics due to limited knowledge of the underlying system, complex nonlinearities, or the existence of unknown exogenous...master thesis 2021

Dinkla, Rogier (author)Wind turbines offer an appealing method for power generation. In the fight against global warming wind energy helps realise green house gas emission reduction targets. Moreover, given a globally increasing demand for energy, the role of wind energy is set to become even more important. Historically, the cost of wind energy has decreased...master thesis 2021

Debusscher, C.M.J. (author)Due to the limited availability of sites on both land and sea, there is a need to maximize the power density of wind farms whilst limiting the adverse wake effect between the wind turbines that cause power losses and/or increased load cases. The study focuses on analyzing the potential of combining yaw-based wake-steering and constant blade...master thesis 2020
