Vortex generators (VGs) are effectively used to improve the performance of the wind turbine blades by means of flow control. VGs can be represented by local geometrical disturbance on the aerodynamic surfaces. This disturbance generates vortices in the streamwise direction, energizing the boundary layer and hence delaying or suppressing the flow...

As on-shore wind farms are being installed in colder and harsher climatic areas in increasing numbers, it becomes more and more important to have adequate measures for dealing with rotor blade icing. Rotor blade icing can lead to a number of serious consequences for the safety, power production, and operation of a wind turbine or entire wind...

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 design of the optimal layout of the wind farm is crucial to minimize the cost of energy produced by the wind farm. This requires an accurate wake model to simulate the wake effect on the annual energy yield of the wind farm. On the other hand, the wake model must be very simple in order to limit the duration of the layout optimisation...

Vortex Generators (VGs) are flow control devices commonly applied in wind turbine blades, among other applications. A significant advance in the design of wind turbine blades would be the integration of vortex generators in the aerofoil optimisation process. Currently, aerofoil optimisation relies on either computational fluid dynamics or...

Wind turbine design is subject to load calculation standards. These determine material use which in turn affects wind turbine costs. Wind turbine cost reductions are important as they contribute to the economic feasibility of wind turbines. Therefore careful evaluation of the load standards is paramount for wind turbine design. This thesis...

For the purpose of flow analysis, the blade of a horizontal axis wind turbine (HAWT) can be divided into the root, mid and the tip regions. The flow in the root region is very complex and is affected due to the rotation of the blade and separation due to the presence of very thick airfoil sections and the higher angle of attacks. Hence, a...

Offshore wind energy is expected to grow in the coming years: future plans for offshore wind farms total more than 98 GW. Financing is needed to realise these plans. Investment decisions partly depend on the uncertainty in energy yield predictions. It is therefore important that these energy yield predictions and their corresponding uncertainty...

One of the main drawbacks of offshore wind energy is its high levelized cost of electricity (LCOE). One explanation for these high costs arises from the large amount of uncertainties that come with such complex projects. As a result of this complexity, it’s difficult to foresee the course of events in advance. Decisions made during the...

The EU goals to decrease wind energy prices are driving the wind energy industry to give more attention to monitoring and improving turbine performance. Meanwhile, as turbines grow bigger and more are placed offshore, performance monitoring costs are increasing, making it more interesting to consider novel devices to measure turbine performance....

The main purpose of this project was the creation of a tool, based on the research performed by Scheldbergen [25] and Roscher [24], capable of performing Finite Element Analysis (FEA) on a Horizontal Axis Wind Turbine (HAWT) blade and minimize its weight by altering the various thicknesses locally, always satisfying a number of structural...

The leading edge inflated (LEI) surf-kite is a suitable wing design for airborne wind energy (AWE) power generation because the bridling and leading edge design allow the wing to be de-powered while retaining good steer-ability. Fluid-Structure Interaction (FSI) modelling is required to capture the flight behavior of an LEI kite, due to it's...

In this research work, the phenomenon of extreme wind events or gusts has been studied in detail and different aspects related to the nature of gusts are explored.<br/>In order to detect wind gusts from a stochastic time series different gust detection techniques collected from previous research works and literature studies were compiled,...

The main driver of developments in the wind energy sector is not the absolute maximization of energy capture, but the reduction of the Cost of Energy (CoE). More and more research is carried out to investigate control of the air flow to reduce fatigue loads, structural requirements, and apply novel control strategies to ultimately reduce this...

In the past, the vertical axis wind turbine (VAWT) lost the competition to its horizontal axis counterpart, having (wrongfully) presumed disadvantages like increased fatigue and low efficiency. Little research and development into the VAWT led to a large gap between the maturity of technology of both turbine types. Now that due to modern...

The project covers creation of a framework for optimisation of wind farm layouts. The optimisation is done with an objective of maximising the Net Present Value of the farm. With that aim, both power production and the fatigue driven component degradation are considered. The work is split in two main parts. First, in order to circumvent the use...

Wind turbines operate in the earth's atmospheric boundary layer - an environment where the climate is turbulent and unsteady. In addition, wind turbines usually operate in clusters (wind farms) and are thus subjected to the unsteady wakes generated by upstream turbines. Because of the unsteady inflow, wind turbines suffer from structural fatigue...

As part of the effort to reduce the cost of offshore wind energy, this thesis addresses the problem of the design of the infield cable topology for offshore wind farms. The final outcome of the project is a tool that can be implemented in a more general optimization platform for offshore wind farm design. Therefore, the main objective is to...
