  1. 6. A Mixed Time-Series & Machine Learning Approach for Price Forecasting in the Swedish Ancillary Market

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen; Lunds universitet/Statistiska institutionen

    Författare :Daniel Arredondo; [2023]
    Nyckelord :Hybrid model; Volatility model; Machine learning model; Price spike prediction; Energy trading; Time series forecasting; Ancillary service market; Business and Economics;

    Sammanfattning : This study aims to forecast the Swedish FCR-D Down A2 market prices through a hybrid model combining a volatility model and a machine learning approach, and compares its performance with a standalone machine learning model. We further examine the impact of different lag orders (1-Hr vs. 24-Hr) on volatility estimates and forecast performance. LÄS MER

  3. 7. On the road to grid stability - Using batteries in heavy vehicles and charging infrastructure as frequency reserves

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Matilda Kjellström; Caroline Wuttke; [2023]
    Nyckelord :Case Study; Electrification; Frequency regulation; Energy reserve; Battery; Heavy vehicles; Vehicle-to-grid; Technology and Engineering;

    Sammanfattning : Background: Climate change and increasing threats that come with it fosters a need for changing from fossil sources of energy to renewable ones. Sweden aims to have net zero greenhouse gas emissions by the year of 2045. One of the sectors that need to take part in this shift towards fossil free energy is the transport industry. LÄS MER

  4. 8. Evaluation of key performance indices for frequency quality : A method for evaluating frequency stability in the Nordic power system

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

    Författare :Sophia Larbi Engelbrektsson; [2023]
    Nyckelord :Ancillary Services; Kinetic Energy; Frequency Dependent Load; Frequency Stability; Frequency Quality; KPI; Nordic Power System; Frekvensberoende Last; Frekvenskvalité; Frekvensstabilitet; Kinetisk Energi; Nordiska Elsystemet; Nyckeltal; Stödtjänster;

    Sammanfattning : The Nordic power system is in a changing phase, with more power electronic interfaced connections, and HVDC connections to other synchronous areas, which impacts the frequency quality. This is a challenge for the transmission system operator of Sweden, Svenska Kraftnät, who, with the other Nordic transmission system operators, is responsible for the physical balancing of the Nordic power system.

  5. 9. Batteries charging into the future? Techno-economical analysis of BESS participation on the Swedish frequency regulation market using a mixed method approach

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Theodor Rosengren; [2023]
    Nyckelord :Battery Energy Storage Systems; Frequency Regulation; FCR-D; FFR; economic feasibility; Sweden; Technology and Engineering;

    Sammanfattning : As the penetration of variable renewable energy is increasing, the demand for flexibility in the electrical grid is on the rise. One way in which flexibility is needed is to provide frequency regulation. If electricity consumption and production momentarily are unbalanced there needs to. LÄS MER

  7. 10. 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
