  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. Impact of power quality on PV performance of grid connected systems

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Ozaveshe Momoh; [2022]
    Nyckelord :Power quality; Power quality monitoring; Electricity grid transmission; Power quality and PV production; Power quality in developing countries; Reactive power; Grid connected systems; Power measurement;

    Sammanfattning : The problem with the implementation of the PV generators is that majority of the UNDP offices are in developing and underdeveloped countries. Majority of these countries experience various problems with the power quality from the national electrical grid. LÄS MER

  4. 3. Optimal Control Actions in an Electrical Grid with Variable Renewable Energy Sources: Evaluation of the ANM4L Control Algorithms

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

    Författare :Erik Boman; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The increasing amount of renewable energy in the electrical grid comes with several challenges, of which overvoltage and congestion (overcurrents) are the subjects of this work. One flexible way of handling these problems is active management by some control system. LÄS MER

  5. 4. Allowing more solar power connected to the grid, using thermal and ageing models of distribution transformers.

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

    Författare :Amena Khatun; [2021]
    Nyckelord :electric power distribution; solar power; renewable-electricity production; hosting capacity; distribution transformers; dynamic thermal rating; component ageing; component overloading.;

    Sammanfattning : Increasing amounts of solar power connected to the low-voltage network will adversely affect the performance of the network. The two impacts that will most often set the limit are overvoltage with the customers and overloading the distribution transformer. LÄS MER

  7. 5. Statistik över svenska blixtströmmar : Analys av data från SMHI:s blixtlokaliseringssystem

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Rebecca Persson; [2021]
    Nyckelord :blixt; blixtlokaliseringssystem; strömfördelning; åskstatistik; SMHI; Svenska kraftnät; åskskydd;

    Sammanfattning : Lightning constitutes a serious threat to the electrical grid. If not protected against, lightning can cause comprehensive damage, harm to humans and lead to disruption in the electricity supply. Modeling of lightning protection is hence an important part of operating the grid. LÄS MER
