In studies of wind plant designs, wake dynamics are of great interests as wakes affect downstream turbine loading that impacts wind plant efficiency. Recent developments of Tensor Basis Decision Tree (TBDT) based machine learning (ML) models in reconstructing the turbulence anisotropy fields of simple flow cases prompt the motivation in applying...

In the coming decade, the Dutch government plans to broadly expand its wind farm real estate over the North Sea region. This is a significant undertaking because, from literature, it is understood that wind turbines can affect the local environment. These impacts include, but are not limited to, changes in variables such as wind speed and...

Wind turbine placement in a wind farm can be optimized to limit power losses due to wakes and improve the economic value of the plant. Seeing as wind farms are increasing in number and size, fast methods to generate good quality layouts can be beneficial for designers. Wind Farm Layout Optimization (WFLO) consists in finding a layout that...

In the Netherlands more wind farms are constructed and energy is contracted in long-term Power Purchase Agreemenats (PPA) to guarantee a steady revenue stream for the wind farm owners. However, until now only large corporates closed PPA contracts to obtain the Renewable Energy Credits (RECs) from a wind farm and claim to be renewable. A new type...

As airborne wind energy is a relatively new field, much of the current research is rapidly progressing towards the development of larger commercial systems with larger airborne components. Farms of airborne wind energy systems can provide higher power generation than a single kite system and offer a potential solution to issues that single kite...

The engineering flow models used to estimate annual energy production (AEP) in offshore wind farm layout optimization typically assume inflow homogeneity over the model domain. This assumption lies in contrast with observations of horizontal wind speed gradients in coastal regions where many offshore wind farms are being constructed. Accounting...

Wind energy is one of the most promising sources of renewable energy and has experienced a very rapid growth in the last 15 years. In order to maintain and sustain this growth wind energy needs to be competitive with the other sources of energy, especially with fossil fuels. A major factor keeping the competitiveness of wind energy is the...

In order to assist project developers in efficient offshore wind farm installation planning a decision-support tool has been developed. The tool combines Discrete Event Simulation and Black-box Optimization. The focus of the development was on providing the flexibility allowing a user to compare various installation strategies and impact on the...

During previous centuries, humanity had relied on fossil fuels to generate the demanded energy. Nowadays, the extensive use of oil, gas and coal for energy production is becoming a major problem which concerns modern society. Global warming and climate change are the biggest challenges the scientific community has faced. The main factor which...

To increase the total wind farm power output, the wind farm layout needs to be optimized. The power output of a wind turbine depends on the incoming velocity, while the velocity is influenced by the wake of the upstream wind turbines. Wind Farm Layout Optimization (WFLO) problems makes use of the so called low fidelity wake models, which...

In the Netherlands, wind power has the highest potential for future development compared to alternatives such as solar PV and biomass. The intermittent nature of the wind power resource calls for novel approaches to supply and demand management, as well as power quality assurance. Energy storage technologies allow for the separation between...

Wind farms are currently built in the North Sea in the Netherlands. The grid connecting the off-shore wind farm to the main-land distribution grid must be protected against short-circuits and other electrical disturbances. In this project is studied if electrical protection of a grid is suitable for grids connecting renewable energy sources to...

Offshore floating wind turbines are one of the newest technologies in the renewable markets today. The world’s first floating wind farm, the Hywind Scotland Pilot Park, was commissioned in October 2017 and has been competitive with fixed bottom offshore wind turbines. There is a global push to make more renewable energy available, but less...

To counteract the effect of climate change, a global agreement was put into force in 2016, aiming to limit the increase in average global warming and reduce greenhouse gas emissions. In that respect, European countries are investing in cleaner sources of energy and predominantly offshore wind, which has seen a rapid growth over the last years....

The design of an offshore wind farm (OWF) is multidisciplinary in nature as it involves the design of many disciplines such as the wake effects, support structure, electrical cables etc. For the optimal design of an OWF, an optimization procedure is required where all the disciplines are optimized simultaneously. The objective function plays a...

In research, the overall power production in a wind farm is typically increased by employing model-based wind farm control. A controller, in an open-loop setting, operates based on the velocity of the wind flow, predicted by a wind farm model. For a controller to achieve the desired level of power production, a wind farm model has to be accurate...

Nowadays an increasing number of offshore wind farms (OWF) is getting built. Several disciplines are considered into this subject. The manual and sequential design approach used so far is not sufficient to guarantee optimized systems because interactions between the different components are disregarded. Therefore, engineering companies are...

The models with different fidelities for the siloed application of niche wind farm disciplines - rotor aerodynamics, aeroelasticity or wake aerodynamics - are prevalent in literature. These models are often used sequentially while designing a wind farm that may lead to a sub-optimal design due to their agnosticism towards the inter-disciplinary...

Surrogate models are used to approximate the expensive ‘true’ simulation codes and thus have the potential to speed up the wind farm layout optimisation problem (WFLOP). One technique to make surrogate models is Polynomial Chaos Expansion (PCE). PCE can approximate a (wind farm) model by using orthogonal polynomials which are constructed based...

Operations & Maintenance (O&M) contributes to about 25% of the total offshore wind farm costs which is rather large. It also influences the levelised production cost per kWh over the entire lifetime of the wind farm. Therefore, it is necessary to reduce the costs involved in O&M activities. One such activity is the logistics involved...
