  1. 1. Grey-box Modeling of Hydropower Plants for Improved Frequency Regulation : Evaluation of Double-Regulated Hydropower Turbines for Fulfillment of the New FCR-requirements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Karolina Engström; Rebecca Waldenfjord; [2023]
    Nyckelord :Double-regulated hydroturbines; Grey-box modeling; FCR-requriements; Frequency contaminent reserve; Hydropower modeling; Dynamic stability; Dynamic performance;

    Sammanfattning : Over the last decades, the frequency on the Nordic electrical power grid has deteriorated. Therefore, new stricter requirements are developed for the hydropower delivering regulating active power on the Frequency Containment Reserve market (FCR). LÄS MER

  3. 2. Assessing the Benefits of Fossil-Free Gas Turbines in Distribution Networks : A Case Study in Västerås

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Fredrik Hansell; Axel Vällfors; [2023]
    Nyckelord :Gas turbine; power system stability; balancing markets; hydrogen; eMethanol; Gasturbin; kraftsystemstabilitet; balansmarknader; vätgas; e-metanol;

    Sammanfattning : As the share of weather-dependent renewable electricity production increases, the demand for power system flexibility grows. In the Swedish power system, gas turbines have historically been utilised for back-up power generation. LÄS MER

  4. 3. Optimization of Kaplan turbines for frequency regulation in hybrid hydropower plants

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Nayan Narkhede; [2022]
    Nyckelord :Kaplan; Kaplan turbines; frequency regulation; hybrid hydropower plants; wear and tear; guide vanes; runner blades;

    Sammanfattning : The increasing penetration of variable renewable energy sources in the Nordic Power System is causing frequency quality degradation and has increased the importance of primary frequency control provided by hydropower plants. Hydropower is the world’s largest renewable energy source.

  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. Modelling and Dynamic Performance of Hydropower in Frequency Regulation : Modelling of Double Regulated Hydropower Turbines

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

    Författare :Kristinn Arnar Ormsson; [2021]
    Nyckelord :Frequency Containment Reserves FCR ; Hydropower; Double regulated DR turbine; Non-linear modelling; Simulink.; Frekvensreserv FCR ; vattenkraft; dubbelreglerad DR turbin; icke-linjär modellering; Simulink.;

    Sammanfattning : The frequency of the Nordic power system has been increasingly deviating outside the normal frequency band (50 ± 0.1 Hz) in the past two decades. In an effort to counteract this, the Nordic Transmission System Operators (TSOs) have proposed new and stricter requirements on the units participating in Frequency Containment Reserve (FCR) market.
