  3. 2. Parallel Operation of Grid-Forming Power Inverters

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

    Författare :Alessia Camboni; [2023]
    Nyckelord :;

    Sammanfattning : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. LÄS MER

  4. 3. Harmonisk strömsimulering i inverterbaserade värmepumpar

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Alexander Magnusson; [2023]
    Nyckelord :Current harmonics; inverter-driven compressor; black box simulation;

    Sammanfattning : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. LÄS MER

  5. 4. Mapping of IPM machine efficiency and Noise Vibration Harshness : An investigation into trade-offs with respect to efficiency and Noise Vibration Harshness

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

    Författare :Bix Eriksson; Erik Rudqvist; [2023]
    Nyckelord :;

    Sammanfattning : Due to the recent shift towards electrification, electric machines has become a prominent option to be used in vehicle applications. Much effort is spent in the development process of these machines to make optimizations in order to improve the performance aspects of the machine. LÄS MER

  7. 5. Study Of Universal Islanding Detection Techniques In Distributed Generation Systems

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)
