  1. 1. Förbättring av nätstruktur i området Forshälla.

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Anton Dafgård; Hugo Junhav Land; [2023]
    Nyckelord :Nätstrukturer; kvalitetsarbete; Uddevalla kommun;

    Sammanfattning : När mycket nybyggnation uppstår i ett område behöver nätstrukturen analyseras för att säkerställa att den befintlig strukturen klarar av det nya effektbehovet. I Forshälla byggs sommarstugor om till permanentboende, nya bostadsområden byggs längst med kusten och hushåll monterar solceller och elbilsladdare på deras hus. LÄS MER

  3. 2. System impact of micro-production

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Annie Haraldsson; [2023]
    Nyckelord :Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

    Sammanfattning : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG. LÄS MER

  4. 3. On Electrification of Heavy-Duty Trucks : A Grid Impact Analysis of Grid Integration of a High-Power Charging Station

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Maria Arvidsson; [2022]
    Nyckelord :Grid Impact Analysis; Electrification; Heavy-Duty Trucks; Charging Station; High-Power Charging;

    Sammanfattning : The Swedish transport sector will need to undergo a major restructuring to achieve the established climate and environmental goals. The biggest change is that fossil fuels will be phased out and a larger part of the vehicle fleet will be electrified. LÄS MER

  5. 4. Design of the model Community to Electric Vehicle to Community (C2V2C) for increased resilience and network friendliness in photovoltaic energy-sharing building communities

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

    Författare :Edgar Mauricio Ocampo Alvarez; [2022]
    Nyckelord :C2V2C; Photovoltaic; Coordinated Control; Electric Vehicle; Electromobility; Power Balance;

    Sammanfattning : Both the solar photovoltaic (PV) installation and electric vehicles (EVs) deployment are increasing significantly in Sweden. With the large-scale integration of PV and EVs, problems such as the voltage deviations and overloading of components can arise, since the existing distribution grids are not designed to host the large shares of new EV loads and the intermittent PV power feed-in.

  7. 5. Numerical Simulation of 3.3 kV–10 kV Silicon Carbide Super Junction-MOSFETs for High Power Electronic Applications

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

    Författare :Rishi Balasubramanian Saraswathy; [2022]
    Nyckelord :Super–Junction; DMOSFET; 4H-SiC; Silicon Carbide; Wide bandgap; 6.5 kV; 10 kV; On-state resistance; Breakdown voltage; Super–Junction; DMOSFET; 4H-SiC; kiselkarbid; bredbandgap; 6.5 kV; 10 kV; framspänningsfall; spärrspänning;

    Sammanfattning : The thesis focuses on designing and characterizing SiC 3.3 kV Diffused Metal-Oxide Semiconductor Field-Effect Transistor (DMOSFET)s with a Ron that is significantly lower than that of current commercial devices. The On-state resistance and breakdown voltage are then adjusted by adding a Super-Junction structure. LÄS MER
