  1. 1. 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

  2. 2. 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

  3. 3. Stability Related Issues for High Wind Power Penetration : Exploring possibilities to enhance grid stability from synthetic inertia in a future scenario

    Magister-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE); Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Christian Ekstrand; Farsad Mansori; [2020]
    Nyckelord :PMSG; Power system stability; PSS E; Synthetic inertia.;

    Sammanfattning : The future global energy transition favour renewables such as wind power, which is predicted to be one of the predominant sources harvesting abundant amounts of energy onwards. Consequently, causing several conventional synchronous generators to be decommissioned in a near future to achieve an overall reduction in greenhouse gases related to electricity generation. LÄS MER

  4. 4. Optimal Day-Ahead Scheduling and Bidding Strategy of Risk-Averse Electric Vehicle Aggregator : A Case Study of the Nordic Energy and Frequency Containment Reserve Markets

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jacob Dalton; [2018]
    Nyckelord :;

    Sammanfattning : The Nordic synchronous grid is facing a number of challenges. The ongoingphaseout of synchronous generation coupled with increased penetration ofintermittent renewable generation is leading to reduced system inertia. LÄS MER
