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...

Kenya is, along with many other countries mainly from Sub-Saharan Africa, suffering from severe problems on access to improved drinking water sources. The country is below the water scarcity threshold and not on track to meet the Millennium Development Goal target related to this aspect, and especially its rural communities are suffering this....

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...

Material bend-twist coupling has been widely studied in the research community as a passive control mechanism for a wind turbine. However, there is a lack of research in incorporating it in the rotor design process, with little research being conducted for its application to small wind turbines. The present study focuses on this issue by...

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...

Due to its inherent dynamic stability the Vertical Axis Wind Turbine (VAWT) is a strong candidate for large (10-20 MW) floating offshore applications. However, there is room for improvement considering the VAWT’s aerodynamic and structural performance, so as to increase its cost-effectiveness. This thesis explores the VAWT’s potential of...

In the last years, large scale Vertical Axis Wind Turbines (VAWTs) are re-gaining a general interest in the wind energy sector as an alternative to Horizontal Axis Wind Turbines (HAWTs). However, the existing standards and guidelines for wind turbine certification do not include specific requirements for VAWT rotors. This thesis aims to study...

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...

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...

Modern multi-megawatt wind turbines are tall and may reach heights of 200 meter. Tall wind turbines require measurements above typical measurement mast height. As tall measurement masts are expensive and cumbersome to install, wind measurements at hub height are scarce. Currently, the use of lidars in wind measurement campaigns is increasing....

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.
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 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...

New concepts for support structures of offshore wind turbines have gained interest in the industry and are examined for intermediate and deep water depths in order to unlock new offshore potential markets. One of the main proposals that has already been commercialized is the three or four leg full height lattice structure. The fatigue assessment...

Large turbines are a synonym of more energy harvested from the wind, but also of increment in the costs. This dilemma has led many researchers on the field of wind energy to wonder about the optimum size for wind turbines concerning the lowest cost of energy. This project studies the optimum turbine size for offshore applications through the...

Experimental Analysis of an Actuator Disk under cyclic unsteady loading.
Wind Energy is one of the cleanest forms of energy. It does not contribute to the greenhouse gases and is also one of the least expensive forms of renewable energy. Due to this, number of wind turbines are increasing annually. Therefore, it is crucial to understand the...

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,...

Wind energy is one of the fastest growing types of renewable energy. Today, offshore wind represents 14% of the EU wind energy market, and has a huge potential for further growth [1]. Operations and Maintenance (O&M) accounts for 18-23% of the total lifetime cost in offshore wind farms, compared to 12% onshore [2]. The offshore O&M tasks...
