Life-Cycle Assessment of a Multi-Megawatt Airborne Wind Energy System

A key motivation for airborne wind energy is its potential to reduce the amount of material required for the generation of renewable energy. On the other hand, the materials used for airborne systems’ components are generally linked to higher environmental impacts. This study presents comparative life-cycle analyses for future multi-megawatt...

Testing and Analyzing of Distance Protection of a Realistic Offshore Wind Farm Transmission System

Modeling Sand Wave Field Dynamics in the North Sea using Delft3D Flexible Mesh

Offshore wind farms are being built at an unprecedented pace in the North Sea. The Dutch government is aiming for a CO2 neutral energy supply by 2050 and vast cost reductions have turned (offshore) wind energy into a worthy competitor for other (green) energy sources. Most of the planned wind farms in the Dutch North Sea are located in areas...

Rogue waves in the Dutch North Sea: An experimental study into the occurrence of extreme waves due to abrupt depth transitions at future offshore wind farm locations along the Dutch coast

Large morphological features, so-called sand ridges, with an average height and length in the order of 10 meters and 3 kilometers respectively are located at future offshore wind farm locations in the Dutch North Sea. Recent literature, considering relatively deep water conditions (kh 1, with k the wave number and h the water depth), has shown...

Towards Active Power Control of Waked Wind Farms: A study in SOWFA simulation environment

The power generated from wind is not synchronized to the electrical frequency of the power grid. Grid balancing services must be assured when the output from a wind farm is integrated into the electrical grid to avoid the risk of blackouts.<b> Active Power Control (APC)</b> methods are employed to provide grid balancing ancillary services such...

Power-to-gas efficiency of a hydrogen back-up system governed by interruptible sources and services

Fossil fuel based energy systems are the main contributor to global warming. As new regulations come into place, a transition towards a more sustainable energy system must be realised. Hydrogen usage is regarded as the key enabler of such systems. The heart of these hydrogen-based energy systems (HESs) is the hydrogen back-up system (HBS) which...

Citizen participation and the wind farm decision-making process: An exploratory case study on the current practice in Dutch municipalities

Wind farms are one of the main means for sustainable energy supply in the Netherlands. In the period of 2013-2020 provincial governments were tasked with siting a certain number of megawatts of wind energy on their territory. This led to the development of wind farms in many Dutch municipalities, of which the decision-making process has in many...

Offshore wind farm decommissioning: An orientation of possible economic activity in the south holland region and the rotterdam port area

A significant part of wind energy in the Netherlands is generated by offshore wind farms at sea. In the coming decades, the number of wind farms will be scaled up in line with current energy transition and sustainability objectives. What happens to these wind turbines when they reach the end of their operational life? What volumes of material...

Mooring System Design for Wind Farm In Very Deep Water: European Wind Energy Master Thesis

Offshore floating wind turbines are one of the newest technologies in the renewable markets today. The world’s first floating wind farm, the Hywind Scotland Pilot Park, was commissioned in October 2017 and has been competitive with fixed bottom offshore wind turbines. There is a global push to make more renewable energy available, but less...

The relation between risk and return in wind park investments

The investment characteristics of wind parks have been analysed, the different risks to which a wind park investor requires compensation, the different models that can translate risk into returns, and finally the returns have been calculated with this model for different wind parks.

The temporary citizen: and the spatial implications of the next mode of energy in Vlissingen

With a new scale of operating and constructing large offshore wind farms, harbours and adjacent cities are facing a transition. This transition will include an increase of work migration and temporary citizens within the area. The construction of a wind farm from the port of Vlissingen-Oost will result in a comings and goings of all kind of high...

Design of a Simple Wake Model for the Wind Farm Layout Optimization Considering the Wake Meandering Effect

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...

Investigating the performance of wind farms with alternating tower heights

Johnstone and Coleman (2012) were among the first to opt the idea of wind farms with mixed tower heights and predicted an increased power production due to the decrease of losses to TKE production from the mean kinetic energy balance. In the current study, the performance of infinite wind farms with alternating tower heights imposed by a...

Engineering an Optimal Wind Farm

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...

Data-driven wind plant control

Each wind turbine in a cluster of wind turbines (a wind power plant) can influence the performance of other turbines through the wake that forms downstream of its rotor. The wake has a reduced wind velocity, since the turbine extracts energy from the flow, and the obstruction by the wind turbine rotor causes increased turbulence. If another...

The Platform and Overall Design of an Actively Stabilised, Manoeuvrable Buoy for Offshore Wind Assessment

It is estimated that in the EU, energy consumption will rise to 4,350 TWh in 2030. Offshore wind farms can provide a solution. The technical wind energy potential for offshore wind farms of the European waters is estimated to be 30,000 TWh annually. For feasibility studies, building and operating offshore wind farms weather assessments are...

A dynamic aggregate model for the simulation of short term power fluctuations

An important aspect related to wind energy integration into the electrical power system is the fluctuation of the generated power due to the stochastic variations of the wind speed across the area where wind turbines are installed. Simulation models are useful tools to evaluate the impact of the wind power on the power system stability and on...
