    Sammanfattning : It is known that Sweden is categorised by being one of the regions that experience low solar radiation because it is located in the northern hemisphere that has a low potential of solar radiation during the colder seasons. The government of Sweden aim to promote a more sustainable future by applying more renewable initiative in the energy sector. LÄS MER

    Sammanfattning : The rise in population causes serious issues in larger cities since the electrical grid is becoming overloaded. Simultaneously, the demand on more sustainable energy production and the use of renewable energy sources increase. Renewable energy based off-grid electrical systems are a possible solution to decrease the magnitude of these issues. LÄS MER

  3. 3. Study of Student Electricity Use in Uppsala

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Max Torbjörner; Anthony Gundstedt; Philip Shaposhnikov; [2020]
    Nyckelord :;

    Sammanfattning : This report covers a project that set out to create our own and implement another existing measurement system that measures the power consumption in different student residences with higher resolution then what is currently offered by Vattenfall. This is important since there is a problem in Uppsala with a lack of power from the electrical grid which limits Uppsalas ability to grow as a city. LÄS MER

  4. 4. An evaluation of flexibility in the EU-project CoordiNet : Could flexibility markets be a solution to capacity shortage?

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

    Författare :Taru Luttinen; Linnéa Eronen; Emma Wiss; [2020]
    Nyckelord :Coordinet; capacity shortage; flexibility; Uppsala; load forecasts; electricity grid;

    Sammanfattning : This bachelor thesis examines the part of the EU-project CoordiNet based on Vattenfall Distribution AB and their commitment in the project. The aim and purpose of CoordiNet are to find possible solutions on capacity shortage through coordination between customer -DSO -TSO achieving a more efficient usage of the electrical grid. LÄS MER

  5. 5. Load following in a Swedish nuclear power plant

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Jacob Bjurenfalk; [2020]
    Nyckelord :chemical engineering; nuclear power; load following; process engineering; electricity production; APROS; Simulations; swedish power gird; kemiteknik; Technology and Engineering;

    Sammanfattning : The energy system in Sweden is currently under a great transformation, where the part of weather dependent energy sources, so called intermittent sources, like solar and wind power will get greater share in the total production of electricity while the production from stable energy sources like nuclear power is decreasing. For a long time, the nuclear power have been operating at baseload and the hydropower as flexible, though, due to the change in the current power system, nuclear power plants may need to transit to flexible operation and apply load following.
