  1. 1. Parallel Operation of Grid-Forming Power Inverters

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alessia Camboni; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  4. 3. Design of a Future Residential DC Microgrid

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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.

    Keywords : Harmonics; microgrid; local energy system; NEPLAN; Technology and Engineering;

    Abstract : “Affordable and clean energy” is EUs 7th Sustainable Development Goal and includes an increase of renewable energy generation in the global energy mix. A lot of the responsibility falls on the energy sector to transform and obtain solutions for a more sustainable future. READ MORE

  6. 5. Model verification and common mode current analysis of grid connected three phase two level converters

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Simon Lindvall; Richard Haraldsson; [2021]
    Keywords : active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Abstract : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. READ MORE
