  1. 1. Analys och vidareutveckling av simuleringsmiljö för LFC-reglering inom NBM-programmet

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Marcus Baumann; [2023]
    Nyckelord :Load frequency control; Power system simulator; Nordic Balancing Model; ARISTO;

    Sammanfattning : The control and balancing measures for achieving safe grid operation in the Nordic power grid is becoming increasingly complex with larger penetrations of renewable power, new guidelines aiming to increase digitalisation and automation alongside integration into European balancing platforms. The power grid operators are faced with new challenges for safely operating the grid leading to an increased need for theoretical and practical education. LÄS MER

  3. 2. Detektering av pendlingar i kraftsystem

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Henrik Lönnberg; [2020]
    Nyckelord :pendlingar; oscillationer; detektering; kraftsystem; elkraft; svenska kraftnät;

    Sammanfattning : Oscillations in power systems are a common problem that cause wear and decreased electric power quality. Hence, it is of great importance to detect when oscillations occur and to analyze which machines that are involved. LÄS MER

  4. 3. Comparison of fast frequency reserve strategies for Nordic grid frequency stability

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

    Författare :Alexander Ismael; [2020]
    Nyckelord :Fast frequency reserve FFR; FCR-D; ARISTO; reduced inertia; renewable energy transition.;

    Sammanfattning :  How long would modern society cope with a power outage, what would happen to vital systems that we today take for granted in modern society. The Nordic electricity grid is facing a major shift where electricity production from non-renewable sources are to be replaced increasingly by renewable sources. LÄS MER

  5. 4. Reactive power control during power system restoration and HVDC investigation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :André Petersson; Christian Bergstrand; [2014]
    Nyckelord :Power restoration; reactor hunting; reactive power control; VSC-HVDC; Technology and Engineering;

    Sammanfattning : As the society gets more and more dependent on electrical energy, it is highly desirable to ensurepower supply at all times. In case of events of natural disasters, simple technical faults or human mistakes, any power system or a large part of it can suffer a blackout. LÄS MER

  7. 5. Validering av vattenkraftmodeller i ARISTO

    Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära

    Författare :Maja Lundbäck; [2013]
    Nyckelord :;

    Sammanfattning : This master thesis was made to validate hydropower models of a turbine governor, Kaplan turbine and a Francis turbine in the power system simulator ARISTO at Svenska Kraftnät. The validation was made in three steps. The first step was to make sure the models was implement correctly in the simulator. LÄS MER
