  1. 1. Power generation and stability of the Swedish electricity system 2045

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Samir Rawashdeh; [2023]
    Nyckelord :Duck curve; peak load; capacity factor; availability factor; stability; synthetic inertia; flexibility; ancillary services; solar power; wind power; hydropower; co-generation; heat generation; nuclear power; hydrogen production; electrolysis; fuel cells; V2G; PtG; P2G; P2G2P; ESS; PSH; SMR; NPP; HPP; FFR; Technology and Engineering;

    Sammanfattning : På grund av energiomställningen, Sveriges mål om att ha en fossilfri elproduktion 2040 samt målet om nettonollutsläpp av växthusgaser 2045 förväntas en omfattande utbyggnad av förnybara energikällor ske. I denna rapport har därför elbehovet, potentialen för elproduktion, möjliga framtida systemproblem samt lösningar undersökts. LÄS MER

  3. 2. Analysis of synthetic inertia using wind turbines for frequency stability in power systems

    Kandidat-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Carl Herrlin; [2022]
    Nyckelord :Synthetic inertia; wind turbines; energy systems; electrical power; Technology and Engineering;

    Sammanfattning : With the large expansion of renewable energy sources such as wind- and solar, the stability and quality of electrical power can be affected. The transition towards large-scale wind power offers many opportunities to maintain stability by using power converters to create synthetic inertia. LÄS MER

  4. 3. Future Nordic Grid Frequency Quality : A quantitative simulation study of current and potential frequency control methods with emphasis on synthetic inertia

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Emil Arvidsson; [2021]
    Nyckelord :grid frequency; synthetic inertia; frequency control; power grid; hydro power;

    Sammanfattning : The power grid faces stability problems due to loss of inertia. The ancillary services balancing the system must be improved to maintain stability. LÄS MER

  5. 4. Inclusion of Wind Turbines into Frequency Support Services : Exploring frequency stability issues and comparing regulation power market products

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Oskar Andersson; [2021]
    Nyckelord :Frequency Containment Reserve; Frequency Restoration Reserve; Fast Frequency Restoration; Synthetic Inertia; Variable Speed Wind Turbine;

    Sammanfattning : There is a trend in Sweden towards increasing the electricity production from renewable energy sources in the electric grid. The increased share of renewables could be seen as essential for Sweden to be able to meet the obligated climate goals. LÄS MER

  7. 5. A Comparison of Grid-Forming and Grid-Following Control of VSCs

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Pontus Roos; [2020]
    Nyckelord :Voltage source converter; Synthetic inertia; Fast frequency response; Power system; STATCOM; Energy storage; Power electronics; Syntetisk svängmassa; Frekvensreglering; Elkraftsystem; energilager; kraftelektronik;

    Sammanfattning : Variable renewable energy sources are today increasingly integrated in the power system as a step towards the renewable society. The large-scale introduction of converter-based energy sources brings challenges in terms of reduced damping to the power system due to the reduced number of synchronous generators. LÄS MER
