  1. 11. 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

  3. 12. APPLYING DISTRIBUTION LEDGER TECHNOLOGY TO MICROGRIDS - A STEP TOWARD THE RENEWABLE ENERGY TRANSITION

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Mirko Bonomi; [2022-08-02]
    Nyckelord :Blockchain; Diffusion of Innovations; Distributed energy resources; Distributed ledger technology; Microgrid; Peer-to-peer energy exchange;

    Sammanfattning : This work focuses on applying distributed ledger technology (DLT) to microgrids and their diffusion in society. The thesis’ purpose is twofold: first, trying to identify the reasons for the slow adoption of microgrid, and second, how DLT can facilitate their adoption. LÄS MER

  4. 13. FEASIBILITY ANALYSIS FOR THE DECARBONISATION OF A DECENTRALISED GRID SYSTEM: A CASE STUDY FOR THE ISLAND OF FUERTEVENTURA, SPAIN

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Pablo Melian Batista; [2022]
    Nyckelord :Hybrid renewable energy systems; HOMER Software; Wind energy; PV; Battery storage; Distributed generation; Decarbonisation;

    Sammanfattning : Decarbonisation of different energy sectors of society is becoming a pressing issue globally withnumerous legislations and objectives being set to decarbonise electrical grids worldwide. Somehave already been met; however, islanded grids still heavily rely on fossil fuels to meet their electrical demand due to the weakness of their grid and limited available space forcing them to use space-efficient technologies such as diesel generators.

  5. 14. Lågspänt likströmsmikronät för effektivisering av solcellsanläggningar

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Theodor Stellmar; Oskar Engman; [2022]
    Nyckelord :solcell; mikonät; likström;

    Sammanfattning : The Swedish energy supply has gone from dispatchable energy sources to more intermittent energy. The conversion to renewable sources such as solar and wind power, also the increasing demand caused by electrification of cars creates increasing challenges on today's electricity grid. LÄS MER

  7. 15. 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.
