The Impact of Wind Shear and Turbulence on the Loads and Performance of Wind Turbines

Operating in real-world conditions, modern large capacity wind turbines often experience off-design situations, enduring dynamic loads characterized by complex unsteady aerodynamics. Key among the challenges in predicting these dynamic loads is understanding the effects of wind shear and turbulence, both individually and in their complex...

Dynamic Modelling of a Solid Oxide Fuel Cell System: Integration of 1-D SOFC Dynamic Model with the Balance of Plant components

The constant pressure on the maritime sector to reduce Greenhouse Gas (GHG) emissions has led the shipping industry to search for alternatives, such as zero-emissions propulsion systems, which would allow meeting the 2050 target imposed by International Maritime Organization (IMO) regulation. Fuel cells have demonstrated to substantially...

Modelling and Simulation of Energy Storage System for Frequency Stability Studies

The frequency stability of the power system is challenged by the high penetration of power electronic interfaced renewable energy sources (RES). This paper investigates the improvements of frequency responses of fully decoupled wind power generators (FDWG) by proposing a novel implementing of ultracapacitors (UC) within a hybrid scheme in real...

The consideration of constrained flow solutions for the purpose of implementing a tidal power plant in the Brouwersdam reconnecting Lake Grevelingen and the North Sea

After the construction of the Grevelingendam (1965) and Brouwersdam (1971), the tidal movement in Lake Grevelingen disappeared. This caused a deterioration of ecological parameters influencing the surrounding flora and fauna and consequently a decline of the water quality set in. Amongst others, Rijkswaterstaat and the provinces of Zeeland and...

Performance of a hydrogen fuel cell scooter used for combined transport and residential power production

A hydrogen fuel cell scooter was tested for the first time to alternatively drive, power electric appliances (Vehicle-to-Load, V2L) and power the grid (Vehicle-to-Grid, V2G). Performance of the scooter is known to rely mainly on the fuel cell stack, and fuel cell degradation depends on the operating conditions. This study aimed to provide...

Tractable Reserve Scheduling Formulations for Alternating Current Power Grids with Uncertain Generation

The increasing penetration of wind power generation introduces uncertainty in the behaviour of electric power grids. This work is concerned with the problem of day-ahead reserve scheduling (RS) for power systems with high levels of wind power penetration, and proposes a novel set-up that incorporates an alternating current (AC) Optimal Power...

Storage sharing at import dry-bulk terminals: A case study at Gadani Energy Park

The Gadani Energy Park is a to-be build project in which ten coal-fired power plants are established at one location near the shore of Karachi, Pakistan. In the initial situation, all power plants manage their own on-shore operations. The objective of this study is to gain insight in the advantages and disadvantages of yard collaboration in bulk...

Developing Attractive Power Plant Portfolios under Long-term CO2-price Uncertainty

Portfolio theory is one of the few convenient theories for analyzing portfolio investments in electricity markets. Originating from financial markets the application of portfolio theory however showed to have difficulties in dealing with the complexities existing power markets. Especially the introduction of CO2-prices caused problems that could...

Finite Element Analysis of a Kite for Power Generation

The kite is modelled with the non-linear finite element method to stay close to its physical properties and represent its full non-linear flexible behaviour. The inflatable beams in the leading edge and struts are modelled with regular beam elements that represent the behaviour to reduce the amount of degrees of freedom drastically. The canopy...

Integration of large scale wind power generation in the Dutch electricity system with interconnections to neighboring power systems

In dit Master of Science onderzoek naar de inpassing van grootschalige windenergie in het Nederlandse elektriciteitsnet inclusief verbindingen naar de omringende netwerken is onderzocht of in Nederland een energiebuffer noodzakelijk is om het wisselende aanbod van windenergie op te vangen. Uit het onderzoek blijkt dat dit echter niet nodig is...

Carbon Dioxide Emission Trade Impact on Power Generation Portfolio: Agent-based Modelling to Elucidate Influences of Emission Trading on Investments in Dutch Electricity Generation

As of January 1st, 2005 CO2 emission trading (CET) is implemented in the EU as a measure to reduce CO2 emissions to counter climate change. It requires that any company that exploits certain activities, such as electricity generation must acquire emission rights to account for its production of CO2. CET does provide an economic incentive to...
