1. 1. Hosting Capacity Methods Considering Complementarity between Solar and Wind Power : A Case Study on a Swedish Regional Grid

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Emma Andersson; Maja Abrahamsson Bolstad; [2023]
   Nyckelord :hosting capacity; hosting capacity methods; renewable power generation; power grid; power system analysis; complementarity; solar power; wind power; deterministic method; time series method;

   Sammanfattning : The demand for electrical power is growing due to factors such as population growth, urbanisation, and the transition from fossil fuels to renewable energy sources. To be able to keep up with the changes in electricity demand, the Swedish power grid must connect more renewable power generation, but also  increase its transmission capacity. LÄS MER

3. 2. Framtidens lågspänningsnät : Analys av utmaningar och lösningar med ny teknik i nätet

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Oscar Dellham; [2023]
   Nyckelord :lågspänningsnät; flexibilitetstjänster; nätförstärkning; elbilsladdare; solceller; lastprognostisering;

   Sammanfattning : With an ever growing demand for electricity, it is tough to know which challenges will be the most pressing and which solutions will be appropriate to implement in different cases. This thesis utilizes simulations of three low voltage grids to see which part of the grid is most vulnerable, to which extent grid reinforcement is needed to solve voltage and load problems, and what amount of demand flexibility services would be an adequate substitute to grid reinforcement.

   Sammanfattning : Access to energy is an important part in the development of most countries and societies, linked to both social and economic growth. Nevertheless, 70% of the population in sub-Saharan Africa does not have access to electricity, which brings consequences to several of these areas. LÄS MER

5. 4. Energikartläggning av mobilt batterilager i kombination med en högeffektsladdare och påverkan på det lokala elnätet

   Sammanfattning : To achieve the established environmental goals, a significant transformation is requiredin the Swedish transport sector. This includes a shift away from fossil fuels and a greateremphasis on electrifying a larger portion of the vehicle fleet. LÄS MER

7. 5. Study Of Universal Islanding Detection Techniques In Distributed Generation Systems

   Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Författare :Ochai Ochalla Danladi; [2023]
   Nyckelord :Distributed Generation; Islanding; Quality Factor; Resonance Frequency; Low Voltage; Medium Voltage; Electronic Power Converter; Inverter;

   Sammanfattning : Energy security, global warming, and climate change have been a major source of global discussions and development. Likewise, the rising cost of electricity for consumers and exponential demand for energy are major factors driving the incremental growth and integration of sustainable forms of energy generation into power the system cycle.
