  1. 1. Local Voltage Control in Converter Based PV Generation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Charlotta Sporre; [2024]
    Nyckelord :distributed generation; active network management; low voltage distribution network; delta control; voltage control; Technology and Engineering;

    Sammanfattning : As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. LÄS MER

  3. 2. 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

  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. Photovoltaic hosting capacity study for a residential area in Uppsala using a synthetic low voltage network

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Ikenna Mbah; [2023]
    Nyckelord :Hosting capacity; performance index; low voltage network;

    Sammanfattning : With the growing acceptance of photovoltaic (PV) systems globally including Sweden, an increasing number of PV systems has continually been installed all through Sweden. In this study, a selected residential area in Uppsala Sweden is considered as a possible site for PV system installation. LÄS MER
