    Sammanfattning : The research work focuses on optimizing various parameters for controlling cells using negative dielectrophoresis and entrapping them in droplet microfluidics. This is achieved by developing a conductivity medium, combining CytoRecovery, BSA, and EDTA, to maintain a steady count of single cells with good viability over an extended period. LÄS MER

  5. 9. Värdkapaciteten för elbilsladdning i lokalnätet; Utvärdering av Monte Carlo-metod i PSS®SINCAL

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Alma Nordqvist; [2023]

    Sammanfattning : The presence of electric vehicles (EVs) in the passenger car fleet has increased at a rapid rate and the development is predicted to continue in the same direction. The charging of these vehicles predominantely takes place in the owners’ homes and thus increases the households’ demand for electricity - both in terms of the amount of energy and the size of power peaks.

  7. 10. 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
