    Sammanfattning : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG. LÄS MER

    Sammanfattning : Energy security, global warming, and climate change have been a major source of global discussions and development. Likewise, the rising cost of electricity for consumers and exponential demand for energy are major factors driving the incremental growth and integration of sustainable forms of energy generation into power the system cycle.

    Sammanfattning : The number of photovoltaic (PV) systems increases annually in Sweden and the installation rate increases every year. The Swedish Energy Agency predict more than a doubling of the amount of electricity generated from PV systems by the year 2025, compared with today’s numbers. LÄS MER

  5. 9. Värdkapaciteten för elbilsladdning i lokalnätet; Utvärdering av Monte Carlo-metod i PSS®SINCAL

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Alma Nordqvist; [2023]

    Sammanfattning : The presence of electric vehicles (EVs) in the passenger car fleet has increased at a rapid rate and the development is predicted to continue in the same direction. The charging of these vehicles predominantely takes place in the owners’ homes and thus increases the households’ demand for electricity - both in terms of the amount of energy and the size of power peaks.

  7. 10. Consumption patterns in low voltage grid : An investigation into typical customers

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Elias Boethius; [2022]
    Nyckelord :;

    Sammanfattning : The climate crisis is more prevalent today than ever before. Many see a clean, carbonfree, electrification as a must if we are to turn this challenge around. Because more andmore of society runs on electricity there has never been a bigger need for an efficientpower grid. LÄS MER
