Hydrogen strategy optimization for a sustainable electricity grid

This master thesis aimed to develop an optimized operating strategy for an electricity grid incorporating hydrogen storage, while considering three key performance indicators: financial costs, reliability, and sustainability. The central research question guiding this study was: "How can the electricity demand be reliably met by a system...

Spatial configurations and learning rules impact on the evolution of cooperative behaviour in the n-person iterative prisoner’s dilemma

Decision-making dynamics and their impact of human behaviour have raised a large number of questions throughout the years. Traits like competition and collaboration amongst agents are often studied, in the context of Game Theory, by the medium of games such as the Iterative Prisoners’ Dilemma.Furthermore, many realistic scenarios and possible...

Modelling of Electric Powertrain for Heavy-Duty BEV

The automotive industry plays a crucial role in battling the climate crisis and reducing emissions. Medium-duty and heavy-duty vehicles alone contribute to one-fourth of global emissions in the transport sector and there is a positive trend in the demand for these vehicles. Battery Electric Trucks have the potential to transform the growing...

Future Hydrogen Town: Designing a PV-Hydrogen-Battery-FC system for atypical neighbourhood in the Netherlands

One of the goals outlined during the Paris Agreement in 2015 aimed at 'holding the increase in global average temperature to well below 2C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5C'. In conjunction with this, the Klimaatakkord of the Netherlands aims to 'reduce greenhouse gas emissions in the...

Optimal Control for Mixed Traffic Inter-Terminal Transport

The control of a dedicated ITT system operating human driven MTSs and AGVs can be centralized, decentralized or distributed. The objective of this research is to find which controller structure is best suited for controlling a mixed traffic ITT system. In doing so, performance differences will be reviewed to gain insight into the effect of...

Controllability of solar-sail orbits in the Earth-Moon system

The propellantless nature of solar-sail propulsion allows researchers to design completely new sets of orbits unreachable or not-maintainable by means of conventional propulsion. The advantage of this somewhat new type of low-thrust propulsion system becomes more evident for long-duration missions where chemical or electrical rocket engines...

Future City Hydrogen: Reality or Utopia?: A techno-economical feasibility study of an optimal stand-alone Solar-Electrolyzer-Battery-FuelCell system for residential utilization

The population worldwide is growing rapidly which leads to an increase of the energy demand. Simultaneously, the established energy resources are being depleted and contribute negatively to the climate. The necessity for a sustainable and inexhaustible energy source, to deal with the increasing energy demand in an ecological friendly approach,...

A Design Tool for Machinery Space Arrangement

The subject of this master thesis is the development of a design tool to help Vuyk Engineering Rotterdam B.V. arrange the machinery spaces (engine room, switchboard rooms, separator rooms) aboard their vessels early in their design process. It applies the field of automatic design generation to a step in Vuyk’s design process to save time and...

Upscaling polymer flooding: Developing a workflow based on particle swarm optimization

In this research a workflow for upscaling polymer flooding is developed. The workflow generates pseudorelative permeabilities (pseudos) to represent flow behaviour affected by fine scale heterogeneities in a coarse grid. With this workflow, a better estimate of the difference in production from a polymer flood compared to a water flood can be...

Optimal Placement and Sizing of Distributed Generation

In this thesis work we solve the problem of optimal placement and sizing of distributed generation by using an original Fuzzy Adaptive Particle Swarm Optimization algorithm and a Mixed Integer Linear Programming formulation of the problem. The goal of integrating Fuzzy Logic in Particle Swarm Optimization is to be able to overcome some of the...

DC/DC Converter For Helicopter Starter/Generator

The use of power electronics DC/DC converters in aircraft has increased due to the state-of-art converters developments. However, the volume, efficiency and mass of such converters are critical issues. Each component of the DC/DC converters contributes to the total mass of the system. By designing each component, optimized to have small volume,...

Improving Global Optimization Methods for Low-Thrust Trajectories

Optimization of spacecraft trajectories is an interesting area of research, where a lot of development takes place: in the past years, an optimizer called OPTIDUS was implemented at the chair of Astrodynamics at Delft Univierstiy. This tool is able to do optimization of spacecraft trajectories (and other problems) using an evolutionary algorithm...
