  1. 1. Mitigation of supply chain uncertainties caused by material shortage : A case study with Loccioni

    Master-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Juliane Wloch; [2023]
    Nyckelord :Supply chain risk management; supply disruption management; semiconductor shortage; Small- and Medium-sized Enterprises;

    Sammanfattning : The ongoing semiconductor shortage impacts organizations throughout the supply chain operationally and financially. Limited material for a sudden increase in demand during the Covid-19 pandemic led to a heightened supplier power and result in the prioritization of customers. LÄS MER

    Sammanfattning : The Swedish power system, similar to those of other European countries, is currently transitioning from fossil to renewable. Simultaneously the electrification and digitalization of societies all over the world sets high standards for the availability of power. As a result the power systems experience certain limitations and issues. LÄS MER

  4. 3. Impact from flexible operation on High Head Francis turbines

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Andreas Skorpen; [2018]
    Nyckelord :;

    Sammanfattning : Today the European energy grid contains more renewable energy sources than ever before, yet there is little to no research on how the increased amount affects the cost structure of the remaining energy sources of the grid. A consequence of phasing more renewable energy sources into the power grid, is a reduction of the overall balancing capacity of the grid. LÄS MER

  5. 4. Grid impact study of frequency regulation with EVs

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Emma Blomgren; [2018]
    Nyckelord :Electric vehicles EVs ; grid impact; ancillary services; frequency regulation; FCR-N; vehicle-to-grid V2G ; voltage; reactive power; load profile; Technology and Engineering;

    Sammanfattning : The ongoing grid paradigm shift has resulted in synchronous generators currently being phased out. As the generators have been providing ancillary services, such as frequency control regulation, this means that new technologies to perform ancillary services need to be developed and evaluated.
