1. Parallel Operation of Grid-Forming Power Inverters
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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
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 teknikSammanfattning : 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
3. Microgrid Protection Strategies for the Swedish Power System
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : 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
4. Design of a Future Residential DC Microgrid
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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.
