At autonomous electricity grids Renewable Energy (RE) contributes significantly to energy production. Offshore resources benefit from higher energy density, smaller visual impacts, and higher availability levels. Offshore locations at the West of Crete obtain wind availability ≈80%, combining this with the installation potential for large scale...

The increasing penetration of renewable energy sources and electric vehicles raises important challenges related to the operation of electricity grids. For instance, the amount of power generated by wind turbines is time-varying and dependent on the weather, which makes it hard to match flexible electric vehicle demand and uncertain wind power...

REScoops are well positioned to spur energy savings among householders and generate investment in renewable energy projects. As compared to other agents in energy markets they have many benefits, particularly their embeddedness in local, social structures. In this paper we explore in which ways, and by using which tools and interventions...

Urban symbiosis is a strategy to create a more efficient metabolism of cities. However, urban symbiosis requires the integration of different systems, which is hard to achieve. Actors involved in existing systems can hardly develop ‘the bridges’ that are required to connect the thus far unrelated worlds of pre-existing systems. This paper...

The integration of renewable energy into the Dutch energy infrastructure raises interrelated operational and market challenges. In their efforts to address them, engineers and economists approach the design of electricity infrastructures very differently, however. While economists focus on a market design that addresses potential market failures...

In many planning domains external factors are hard to model using a compact Markovian state. However, long-term dependencies between consecutive states of an environment might exist, which can be exploited during planning. In this paper we propose a scenario representation which enables agents to reason about sequences of future states. We show...

With the advent of Smart Energy Systems and Energy Cooperatives in the Netherlands and elsewhere, sharing of renewable energy within neighbourhoods is likely to gain wide prominence in the near future. Today the concept of 'Energy Sharing' is often limited to householders 'selling' their surplus of locally generated energy to the energy grid....

More and more residents’ groups in the Netherlands are undertaking collective initiatives for sustainable energy optimalisation. This is the result of growing environmental awareness, decreasing government intervention and increasing civil initiative. However, the contribution to the national move towards sus-tainability is, according to the...

Biomass is a sustainable energy source which, through thermo-chemical processes of biomass gasification, is able to be converted from a solid biomass fuel into a gas mixture, known as syngas or biosyngas. A solid oxide fuel cell (SOFC) is a power generation device that directly converts the chemical energy of a fuel to electricity. Therefore,...

In this paper we investigate the charging coordination of battery electric vehicles (BEV) with respect to the availability of intermittent renewable energy generation considering individual real world driving profiles in a deterministic simulation based analysis, mapping a part of the German power system in 2009. We propose a price based...

The estimated growth of Europe’s electricity demand and the policy goals of mitigating climate change result in an expected increase in variable renewable energy. A high penetration of wind and solar energy will bring several new challenges to the European electricity transmission network. The objective of this paper is to understand the effects...

The pile-soil interaction is of great importance in the design of monopiles supporting offshore wind turbines. Especially the predication of accumulation of rotations, change in stiffness and damping is difficult. The design tools used today cannot in a proper way take the effects from cyclic, lateral loading into account. In order to develop...

Purpose - The increasing concern for adverse effects of climate change has spurred the search for alternatives for conventional energy sources. Life cycle assessment (LCA) has increasingly been used to assess the potential of these alternatives to reduce greenhouse gas emissions. The popularity of LCA in the policy context puts its...

ElectroHydroDynamic Atomisation (or electrospraying) is a way to disperse a liquid into droplets by exposing it to a strong electric field. The resulting droplets are (highly) charged and can exhibit narrow size and charge distributions which is desirable for many applications. In this dissertation a novel method is developed to classify the...

A new concept for wave energy conversion is examined as a proof of concept for generating electricity in a moderate wave climate while being integrated in a caisson breakwater. Physical model testing is performed to analyse the preliminary efficiency of the device and to identify areas of improvement. The resulting device is calculated for two...

The analysis, modeling and design of the lift-driven Vertical Axis Wind Turbine (VAWT) has challenged the wind energy community for many decades; this limited progress in knowledge has severely impaired the development of the VAWT, giving rise to the myth that the VAWT rotor is inherently inefficient (in comparison with the more conventional...

An increasing number of small Distributed Generation (DG) units are connected to the grid. The introduction of DG causes several problems, which are mainly related to the differences between DG units and conventional generators. Four problems have been considered in this thesis: damping of harmonics, voltage control, the behaviour of DG units...
