    Sammanfattning : To mitigate the carbon footprint and the need to fulfil the energy goals in terms of sustainability, it is required to deploy a large integration of green energies. Therefore, in the previous and the coming years, there will be a high research and technological interest in the high penetration of converter-based generation. LÄS MER

  3. 2. Frequency Response from Inverter-Based Generation

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

    Författare :Johanna Lindstén; [2020]
    Nyckelord :;

    Sammanfattning : The system inertia of the Nordic power system is expected decrease in the future. This is due to an expected reduction in synchronous generation from nuclear and thermal power. This will be compensated by an increase in power from inverter-based generation due to wind power’s expansion in the power system. LÄS MER

  4. 3. Evaluation of critical fault scenarios for operation with inherent overload in HVDC stations

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Lisa Sander; [2018]
    Nyckelord :HVDC; Modular multilevel converter; VSC; transient currents; transient voltages; inherent overload; converter bus fault; pole to pole fault;

    Sammanfattning : The HVDC, High Voltage Direct Current, is important when it comes to upgrading the energy system to a renewable, sustainable and efficient system. This master thesis is investigating what is happening during the most decisive fault cases when the HVDC station is operating with inherent overload. LÄS MER

  5. 4. Interface Between Process Equipment And Process Bus for Light Weight Testing Of Protection Functions
