  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.

  4. 3. Pathways towards universal access to electricity in West Africa : Case study of Mali and Senegal

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Vittorio Bozzo; [2023]
    Nyckelord :Universal electricity access; Senegal; Mali; OnSSET; GIS; PV mini-grid; Universell tillgång till el; Senegal; Mali; OnSSET; GIS; PV mininät;

    Sammanfattning : Despite the vast solar potential in both Mali and Senegal, the electricity access in both countries remains one of the lowest in the world. The main problem is represented by the disparity between rural and urban settlements. In Senegal, the electricity access for rural areas was lower than 50%, while in Mali was around 35%. LÄS MER

  5. 4. Design of a Sustainable Energy System for a Community Center in rural Mozambique : A Minor Field Study in Mozambique

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Emilia Säll Magnusson; Melchior Hahn; [2023]
    Nyckelord :Sustainable energy system; Solar PV system; off-grid; Community center; Rural Mozambique; Minor Field Study; Project Vita; Hållbart energisystem; Solcellssystem; off-grid; kultur- och fritidscentrum; Mozambiques landsbygd; Minor Field Study; Project Vita;

    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

  7. 5. Monitoring of Partial Discharges on Cable Terminations : An experimental approach to evaluate non-conventional online PD measurement techniques

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

    Sammanfattning : The transmission of electric power over long distances has historically posed challenges. However, the advent of high-voltage engineering has not only addressed distance barriers and power losses in electricity transmission and distribution, but it has also significantly improved the efficiency and transmission capacity of power grids.
