Energy demand from wind greatly increases, as such more remote sites need to be explored in order to find good wind resources. These remote sites are driving the industry further offshore and therefore into extreme wind and sea conditions. This push towards extreme conditions requires technological advancements concerning the wind turbine loads,...

The wake geometry of a Vertical Axis Wind Turbine (VAWT) is unlike the standard Horizontal Axis Wind Turbine (HAWT). The blades of the turbine continuously passes through its own wake, creating complex wake-body interactions such as flow separation and dynamic stall, and convectional grid-based numerical method which is capable of describing...

It is the objective of this graduation research to determine the nations with the highest deployment opportunity for airborne wind energy (AWE) generation systems. Compared to conventional, ground based, wind energy systems, the flying structure of the airborne wind turbine substitutes the rotor blades and a tether substitutes the tower. These...

As the world demands cleaner, sustainable and economical energy sources, the wind energy academia and industry battles to increase performance and reduce costs. One of the promising fields of study is wind turbine wakes in wind farms. The position of the turbines within the layout affects the intensity of their wake effects, such as reduced wind...

In an effort to achieve economic sustainability, the major challenge for offshore wind remains to bring down costs by approximately 35 % before 2020. With wind farm sites going into deeper waters, further from shore, with more difficult bottom conditions and rougher wave climate, costs are rising faster than the improvements in the technology...

The world’s energy consumption is rising, which will eventually result in the depletion of fossil fuels. A transition from fossil fuels to renewable energy sources as main energy supply has to be achieved to ensure the world’s energy supply on the long term [9]. To ensure the world’s energy supply, the European Commission adopted the climate and...

Low level jets (LLJs) are situations where wind speed maximums occurs close to the surface. Unfortunately, the influence of LLJs on wind turbine power production is still difficult and costly to quantify due to that the existing LLJ models are all time-based. The work that is done in this report addresses the research question should low level...

Given the prime importance of wind tunnel setup when it comes to aero-elastic study, the main intent of this project is to devise a mechanism for supporting system of 2D aero-elasticity experiment in the Red Wind Tunnel Facility at DTU that allows three-degree-of-freedom motion of the rigid model. This project work is mainly inspired by the fact...

Wind turbine noise has become an important issue when developing onshore
wind farms as turbines have scale up rapidly in the latest decades. The interest of this project is focused on the characterization and modelling of noise as a source based on the specific physics from wind turbines. A dedicated evaluation of wind turbine noise...

Currently, the price per kW of offshore wind energy is 55% larger than onshore [38, 52]. Of this price, the rotor corresponds to 22%. To reduce the price of wind energy, it is necessary to investigate wind turbine concepts with scales above 10 MW. The commonly known Horizontal Axis Wind Turbine (HAWT) requires offshore a large support structure....

In a world where renewable energy sources are becoming more relevant, wind energy takes an important position in the current and future energy market. In order to become a bigger player in this market it is first important to provide a solid reliable product. To this extent, it is important to consider classical flutter for a wind turbine, as...

In recent years the global demand for sustainable energy has risen. In search of new sustainable energy sources, Delft University of Technology’s KitePower group developed an airborne wind energy system. This system is based on a pumping cycle principle where a kite is reeled out with high traction forces while turning a generator, and reeled...

Offshore wind energy is expected to generate a large part of Europe’s sustainable electrical energy by the year 2020. In the design of an offshore wind farm a large number of components interact with each other, resulting in a certain cost of electricity. In order to reduce these costs of electricity the design of an offshore wind farm can be...
