  1. 1. Local voltage control in a low voltage grid with high photovoltaic penetration

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Joakim Bakklund; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

  3. 2. 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

  4. 3. 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.

  5. 4. Analys av påverkan från ökad mikroproduktion och installation av laddare för elfordon i lågspänningsnät

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :John Andersson; [2023]
    Nyckelord :rechargable card; charging stations;

    Sammanfattning : In Sweden, the number of rechargeable cars increases for every year. It is common to charge at home, for example because there is no need to wait for the vehicle to be fully charged.Charging at home takes place with low effects for longer time periods. The installation of micro production with photovoltaic systems is also increasing. LÄS MER

  7. 5. 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
