Remaining Useful Life (RUL) estimation is directly related with the application of predictive maintenance. When RUL estimation is performed via data-driven methods and Artificial Intelligence algorithms, explainability and interpretability of the model are necessary for trusted predictions. This is especially …

The dynamic inflow effect denotes the unsteady aerodynamic response to fast changes in rotor loading due to a gradual adaption of the wake. This does lead to load overshoots. The objective of the paper was to increase the understanding of that effect based on pitch step experiments on a 1.8 m diameter …

Presentation for the Distributed Wind Summer 21 meeting of Task 41 of the International Energy Agency Wind Technology Collaboration Platform (IEA Wind TCP)

From the start of the energy transition is has been believed that the development of wind power as a renewable source of electricity was vital for reaching the climate goals related to the decarbonization of the energy sector. The LCOE variable is globally applied when comparing the cost for the use …

In dit onderzoeksrapport wordt het onderzoek en ontwerpproces beschreven dat als doel had het vinden van de meest geschikte methode voor het meten van mechanisch vermogen, interne spanningen, toerental, bladpositie, watersnelheid en waterniveau van en om een verticale as waterturbine van het type Darrieus. Om …

This chapter discusses several aspects related to engineering methods in wind turbine design codes. Current engineering models for rotor aerodynamics topic are built around the Blade Element Momentum (BEM) theory. The Blade Element Momentum theory in itself is very basic, e.g., it is derived for two-dimensional, …

In this presentation a new EA Wind Task is presented, i.e. an international cooperative project on the field of aerodynamic wind turbine measurements organised under auspices of the IEA

Renewable energy systems are a crucial technological development needed to combat climate change. This thesis covers the design and implementation of a mathematical optimization model, which calculates the lowest cost of hydrogen for certain renewable energy system configurations. The output of the model …
