  3. 22. On the road to grid stability - Using batteries in heavy vehicles and charging infrastructure as frequency reserves

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Matilda Kjellström; Caroline Wuttke; [2023]
    Nyckelord :Case Study; Electrification; Frequency regulation; Energy reserve; Battery; Heavy vehicles; Vehicle-to-grid; Technology and Engineering;

    Sammanfattning : Background: Climate change and increasing threats that come with it fosters a need for changing from fossil sources of energy to renewable ones. Sweden aims to have net zero greenhouse gas emissions by the year of 2045. One of the sectors that need to take part in this shift towards fossil free energy is the transport industry. LÄS MER

  4. 23. Energigemenskaper - En framtidslösning? : En studie om energigemenskapers utveckling i Sverige

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Petra Lindberg; Linnea Ljungberg; [2023]
    Nyckelord :Energy community; Energigemenskap;

    Sammanfattning : The energy system is undergoing a major transformation where the dependence on fossil fuels needs to be replaced with solely sources of renewable energy. The increased share of renewable intermittent electricity production, together with urbanization, electrification, and digitalization, creates challenges for the operation security in the electricity system.
