  1. 1. Model on degradation of PEM fuel cells in marine applications

    University essay from KTH/Kemiteknik

    Author : Erik Östling; [2021]
    Keywords : Proton exchange membrane fuel cell PEMFC ; marine applications; durability; lifetime prediction; empirical model; PEM bränsleceller; marina tillämpningar; hållbarhet; livslängdsberäkning; empirisk modell;

    Abstract : Sjöfarten står för 3 % av världens totala växthusgaser och är idag högst beroende av fossila bränslen. Ett alternativ för att gå över till en fossilfri flotta är användning av bränsleceller och vätgas som drivmedel. READ MORE

  3. 2. Active Phase Balancing and Battery Systems for Peak Power Reduction in Residential Real Estate : An Economic Feasibility Study

    University essay from KTH/Industriell Management

    Author : Jacob Westerberg; [2020]
    Keywords : Phase balancer; Load-side peak shaving; Economic feasibility; Techno-economic assessment; Battery energy storage system; Stockholm Exergi; Fasbalansering; Topputjämning; Ekonomisk genomförbarhet; Tekno-ekonomisk analys; Batterisystem; Stockholm Exergi;

    Abstract : Research has shown that three-phase balancing alone can improve the operation of secondary distribution networks and that the addition of energy storage to the phase balancing power electronics further helps to alleviate the negative effects of phase unbalances. However, less attention has been paid to the economic potential of said technologies and particularly for loadside implementation. READ MORE

  4. 3. Optimization of wind turbine loads for maximum power output and low fatigue loading

    University essay from KTH/Kraft- och värmeteknologi

    Author : Wondmagegn Ergano; [2020]
    Keywords : ;

    Abstract : In this thesis the aerodynamic loads for maximum power output at acceptable fatigue loads on a 1.5MW onshore wind turbine are examined. READ MORE

  5. 4. Load Classification with Machine Learning : Classifying Loads in a Distribution Grid

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Jonathan Kristensson; [2019]
    Keywords : Power systems; machine learning; smart grid; load profiles; Velander s formula; load classification; clustering; regression; data quality; Kraftsystem; maskininlärning; smarta elnät; lastprofiler; Velanders formel; lastklassificering; klustring; regression; datakvalitet;

    Abstract : This thesis explores the use of machine learning as a load classifier in a distribution grid based on the daily consumption behaviour of roughly 1600 loads spread throughout the areas Bromma, Hässelby and Vällingby in Stockholm, Sweden. Two common unsupervised learning methods were used for this, K-means clustering and hierarchical agglomerative clustering (HAC), the performance of which was analysed with different input data sets and parameters.

  6. 5. Design of Experimental Setup for Investigation of Effect of Moisture Content on Transformer Paper Ageing during Intermittent Load

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Patrik Gustafsson; [2018]
    Keywords : Dynamic Transformer Rating; transformer; moisture content; paper ageing; cellulose ageing; intermittent load; experiment; experimental setup;

    Abstract : In this project an experimental setup is designed to investigate the effect of intermittent load patterns in combination with moisture content on cellulose ageing. It is done by exposing groups of samples to different intermittent load patterns with varying frequency. READ MORE
