  1. 1. Grid Scale Storage Placement In Power Systems

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Andreas Bodegård; [2022]
    Nyckelord :FFR; frequency regulation; PowerFactory; DIgSILENT; grid scale storage; inertia; power system; rotor-angle stability; frequency stability; modal analysis; kundur two area model; nordic32;

    Sammanfattning : The increasing amount of renewable energy sources is applying more and more pressure on today’s power system. Additionally, plannable sources of energy, which are mostly non-renewable, are being decommissioned at a high rate to combat climate change. LÄS MER

  3. 2. Evaluation of Power Oscillation Damping in the Nordic Grid Using HVDC

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

    Författare :Johan Hansson; [2020]
    Nyckelord :;

    Sammanfattning : With a rapid transition towards renewable energy sources and increasing demand for electricity, we are facing major changes in the electricity grid. With increased congestion and reduction of inertia the grid is becoming more sensitive to rotor angle stability issues, such as the stability of interarea modes or power oscillation damping (POD).

  4. 3. Detection and location of HVDC commutation faults from PMU data

    Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Alejandro Belinchon Calderon; [2018]
    Nyckelord :HVDC-links; HVDC converters; Commutation failures; Phasor measurement units PMUs ; Electric power systems; Wide Area Measurement systems WAMS ; Standard IEEEC 37.118; Single-line to ground faults; Three-Phase faults; Fault detection and location; Nordic 32; DigSilent-PowerFactory; PSCAD; MATLAB-Simulink; Symmetrical components.; Technology and Engineering;

    Sammanfattning : Commutation Failures in LCC HVDC converters is a topic that is normally addressed from the component perspective, looking at converters’ internal signals. How these commutation failures affect the outer AC network is not deeply understood yet. LÄS MER

  5. 4. On the impact of wind power on CO2 emissions in a power system

    Master-uppsats, KTH/Elkraftteknik

    Författare :Charlotta Ahlfors; [2017]
    Nyckelord :;

    Sammanfattning : This master thesis is carried out at KTH Royal Institute of Technology in Stockholmthe spring 2017. The project analyses the impact of wind power in a power system.A fictitious power system, created from the Nordic32 test system, is used for theanalysis. LÄS MER

  7. 5. 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
