A new wind shear relation is derived based on the atmospheric equations of motion, which are, in turn, based on the Navier-Stokes equations. In order to make the obtained system of equations solvable, it is assumed that the air density and pressure follow the International Standard Atmosphere relations and that the wind speed is constant over...

Monitoring and optimising turbine performance are important tasks of a wind energy operator. However, monitoring activities are expensive and the current state-of-the-art in this field could be improved. A newly developed Avent five-beam Lidar was tested and the impact of heterogeneity on Lidar measurements was analysed. Also, the effect of...

Wake effects in wind farms are a major source of power production losses and fatigue loads on the rotors. It has been demonstrated that in large wind farms the only source of kinetic energy to balance that extracted by the turbines is the vertical transport of the free-stream flow kinetic energy from above the wind-turbine canopy. This chapter...

Wind assessment of new locations prior to the installation of wind turbines is an established process. However, this process is still very costly. The common way to measure offshore wind profiles is the usage of met masts, which get more expensive with increasing water depth and hub height. Recently, wind measurement LiDARs are installed on...

Communication in wind farm development is complex. A relationship between wind farm developers and residents which is based on reciprocity can lead to the trust and commitment necessary to deal with these complexities. The role of reciprocity is researched in a case study and a network model of reciprocity is developed. Implementing the findings...

The market share of wind energy is related to many factors, including politics, social acceptance and financial feasibility. In light of reducing the Levelised Energy Cost (LEC) generated from wind energy, power company Vattenfall is continuously looking for new ways of monitoring and improving wind turbine yield. Recent publications have shown...

Inspired by the world's first timber tower for a multi-megawatt turbine, an investigation has been carried whether or not this design would be suited for Dutch wind conditions as well. Demands from design codes have been summarized and the frequency behaviour of these timber towers has been studied. Apart from the original softwood Cross...

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...

In this study, the offshore wind farm effects of Thanet (300 MW) in the U.K, and of Middelgrunden (40 MW) in Denmark were analyzed in a meso-scale numerical prediction model, whilst working at MeteoGroup. For the final analysis of Middelgrunden, the model is validated with measurement data from Middelgrundens Vindmøllelaug. The model uses...

Power curves are a fundamental element of any wind resource assessment. These are required to estimate how much energy a wind turbine will convert. The theoretical power curves are validated with measurements in test sites, however they may not be fully applicable in different wind climates as they are dependent on the site where, and the...

Load simulations play an important role in the design, certification and optimization procedures for the development of reliable and cost efficient offshore wind turbines (OWTs). For load simulations of OWTs, aero-hydro-servo-elastic tools are used. However, the joint flexibilities of the support structures are generally not modeled in detail in...

Thunderstorm gusts can be severe and inflict major damage to high buildings such as wind turbines. These gusts are caused by the downburst emanating from the thunderstorm cloud. In this research, thunderstorms are modelled for wind turbine design. The results of this study might help make the design of wind turbines thunderstorm-proof. Not only...

In the past decades, offshore wind energy has emerged as one of the most promising renewable alternatives to the traditional fossil sources of energy. Although the ocean has a vast potential, with higher wind speeds and lower turbulence levels than onshore, the required marine foundations make the realization of an offshore wind farm expensive....

A pumping kite system is a new innovative way to generate sustainable energy. A large kite is used to generate a pulling force which is transmitted to the ground by a tether. The tether is reeled off a drum that is connected to a generator. When the tether is completely unwound the kite is controlled in such a way it hovers down like a parachute...

Uncertainty in aerodynamic load prediction is an important parameter driving the price of wind energy and thus the wind turbine community is in need of more sophisticated tools for evaluating aerodynamic blade loading. Blade Element Momentum (BEM) theory is the current standard for estimating the wind forces in load case calculations. The...

Wind turbine rotor blades have seen a strong growth in length and industry is facing new structural problems. New lighter and stiffer materials would be useful to improve the blade design. This research analyses the potential of carbon glass hybrid composites. Three laminates typical of the laminates used in the spar caps and in the trailing...
