  1. 1. 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

  3. 2. Krav för inmatning av el till nätet från batterier : Undersökning av villabatterier och elbilar via V2G

    M1-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Magnus Kallin; [2023]
    Nyckelord :requirements; energy storage; battery storage; islanding; V2X; V2L; V2H; V2G; electric vehicles; EV; krav; inmatning; energilager; batterilager; ödrift; V2X; V2L; V2H; V2G; elbilar; EV;

    Sammanfattning : Dagens samhälle har stort beroende av central elförsörjning för att ha kapacitet att fungera. Beroendet av centrala produktionsenheter kopplade till stamnätet kan i sin tur göra det svenska elnätet mer sårbart och ostabilt. LÄS MER

  4. 3. Microgrid Protection Strategies for the Swedish Power System

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Zalak Shah; [2023]
    Nyckelord :Microgrid; Protection; three-phase fault; earth fault; Technology and Engineering;

    Sammanfattning : This thesis mainly focuses on the protection strategies of microgrids for the Swedish power system in the medium voltage distribution system and specifically on the three-phase fault and earth faults protection strategies. For the analysis of both faults, different grid-connected, and islanding operations are simulated using DIgSILENT Power Factory. LÄS MER

  5. 4. Design of a Future Residential DC Microgrid

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

    Författare :Viktor Andersson; Max Gugolz; [2022]
    Nyckelord :Grid control; grid converter; DC microgrid; buck-boost; PV; MPPT; P O; ESS; SOC;

    Sammanfattning : In the search for environmentally friendly methods to implement renewable energy in the power system residential microgrids have been proposed and proven. The direct current (DC) microgrid topology is a promising implementation of a microgrid system due to the increasing amount of DC-operated loads and production units expected in the near future.
