Cost is a design driver in any commercial business, and this is not different in the wind energy industry. The potential of cost savings on wind turbine towers through lightweight composite designs has been shown. However composite grid stiffened and lattice structures, which were shown to lead to significant weight reductions in aerospace...

As electricity demand increases and fossil fuels are depleted, renewable energy technologies are on the rise in order to keep up the supply of energy. Since wind power is the technology with the most promising for large-scale implementation, it becomes important to understand what wind power brings to system operation. Wind is by nature variable...

A global focus on the shift to renewable energy has introduced international targets for sustainable energy production, which have strongly increased the interest in offshore wind turbines (OWT’s). In order to make offshore wind energy even more competitive, the levelised cost of energy for this industry has to be brought down. One of the OWT...

Aeroelastic codes are fundamental for the design of wind turbines and the prediction of instabilities. Such codes rely on engineering models which limit their accuracy. With wind turbine blades becoming more slender to lower the costs, it is important to reduce these uncertainties to maintain a safe and stable turbine design. The dynamic stall...

Wind energy plays a major role in the ongoing energy transition. To accelerate the adoption of wind energy and thereby the energy transition, the Levelized Cost of Energy (LCOE) has to be minimized. Apart from increasing turbine performance, reducing turbine down-time can contribute to lowering the LCOE.Down-time is defined as time during which...

<br/>Wind energy currently is one of the most attractive solutions to help in the goal of switching to a more sustainable way of energy production. To stay competitive with other forms of energy production, the reduction of the Levelized Cost of Energy (LCoE) is an important indicator. One way of achieving this goal is by increasing the size of...

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...

Wind Power Producers (WPP) incur a negative result through mandatory participation on the balancing market. This study analyzes the performance of multiple improved offering strategies for a WPP offering both on the day-ahead market and the balancing market. It does so on revenue, as well as its impact on the grid and electricity market as a...

Flows over complex terrains present uncertainties in wind farm power production and lifespan. Core to these uncertainties are wake dynamics, which lack adequate models and need further validation. In lieu of conducting field experiments, this study integrates scanning lidar measurements and large eddy simulation (LES) to characterize wakes in...

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 energy has emerged as a promising alternative to fossil fuel energy sources over the last two decades partly due to considerable reductions in the cost of power production. A common trend towards cost reduction has been to build larger and lighter wind turbines. These produce more power per unit and use less material. Another strategy for...

Recent Spanish legislation has enacted a complete reform of the energy sector in efforts to balance system costs with revenues and reign in the accumulating tariff deficit. Under the new legislation, wind energy and other renewables must compete against traditional thermal and hydro plants, yet are not allowed in the ancillary services market...

As the penetration of offshore wind farms continues to increase in Western Europe, the North Sea in particular is becoming more densely populated by offshore wind farms. Wind turbine wakes have been a topic of great research in the field of wind energy for some time, however the industry now seeks an understanding of the in- fluence of the wake...

With the shift towards a more sustainable energy society, the increase in the electricity produced by renewable energy sources is steadily rising. However the cost of renewable energy sources still remains high compared to the traditional fossil fuel based energy sources. With the total worldwide energy demand also rising, combining renewable...

Traditionally a wind turbine’s power curve is used to model the long-term energy yield of the wind turbine and afterwards assess the performance of the turbine (power curve verification). But the current power curve is typically univariate: only dependent on the wind speed and slightly adjusted for site density, turbulence intensity and wind...

The wide scale integration of distributed energy resources (DERs) in the distribution networks (LV/MV) over the last few decades has resulted in new challenges for the protection system. This thesis work explores the possibility to overcome challenges associated with overcurrent protection schemes, which are conventionally employed for...

The purpose of this research is to broaden current knowledge of Wind Farm Layout Optimization (WFLO). Until now, there are many research conducted on different optimization methods, annual energy yield calculation processes, and wake modeling methods. But, few papers have addressed the effect of different modeling parameters on WFLO in a form of...

In this comparative eco-design study, the environmental impact of LM’s 58.7 blade was assessed for multiple material composition and waste management scenarios. Material variations were largely focusses on the resin fraction of the blade. This is since the matrix has the biggest impact of all materials and has a big impact on the available waste...

In the future, it is expected that the European Power Grid will be integrated with several sources of renewable energy producers (mainly wind/solar), alternating their maximum/minimum production periods per year. All involved parts of the European Power System (generation and consumption units) will increasingly be connected to the network...
