  1. 1. Wind power forecasting using random forests

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Christoffer Ahrling; [2023]
    Keywords : machine learning; wind power; forecasting; random forest; Technology and Engineering;

    Abstract : The present thesis investigated using the random forest machine learning algorithm for wind power forecasting. Meteorological prognoses for wind speed, wind direction, gust winds, and humidity were used. For historical data, wind minimum and temperature was also included. READ MORE

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

  4. 3. Mounting of Inner Support Structure on the Swedish Warship Vasa : Product Development

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Camilla Granbom; [2020]
    Keywords : Product development; mounting;

    Abstract : The master’s thesis is focused around the mounting of an inner support structure to the Swedish warship Vasa and was given by Camatec Industriteknik AB. The Swedish warship Vasa is one of the greatest national treasures of Sweden. The ship was built high and narrow, therefore a small gust of wind made her capsize during her maiden journey. READ MORE

  5. 4. Aeroelastic Analysis of a Morphing Wing for Airborne Wind Energy Applications

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Johannes Hall; [2017]
    Keywords : airborne wind energy; fluid structure interaction; gust wind modelling; Technology and Engineering;

    Abstract : The aim of this thesis is to set up a high-fidelity fluid structure interaction (FSI) simulation environment to study the gust load alleviation capability of camber-morphing airborne wind energy (AWE) wings. The simulation environment will enable studying the transient flow phenomena around the wing when encountering wind gusts and gives the possibility of investigating dynamic instabilities. READ MORE

  6. 5. Estimation of Resource Allocation Based on Disturbance Prediction Data with Use of Statistics, Machine Learning and Data Analysis

    University essay from Lunds universitet/Matematik LTH

    Author : Rebecka Domeij; Richard Luong; [2017]
    Keywords : outages; prediction; negative binomial regression; logistic regression; decision tree; Mathematics and Statistics;

    Abstract : The electrical power grid is one of modern society’s most important infrastructures and both power distributors and the Swedish government are investing large amount of resources to ensure continuous delivery of power. By predicting future outages with an automatic prediction system, the distributors could prevent long restoration times and economic loss. READ MORE
