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. Virtual power lines in the future Swedish power system

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

   Författare :Simon Hessman; Frida Lundberg; [2023]
   Nyckelord :VPL Virtual Power Line Nordic44 Nordic46 BESS Energy Storage; Technology and Engineering;

   Sammanfattning : The transition towards renewable energy and electrification is expected to accelerate in the coming decades. This change is being studied by several actors, in Sweden most notably by Svenska kraft- nät, the Swedish TSO. LÄS MER

5. 4. Power system balancing in Swedish future scenarios of 2045 - Estimating contributions from V2G

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

   Författare :Pontus Herrmann; Julia Jonasson; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The ongoing climate change calls for an immediate decarbonization of society, where one important measure is a rapid transition of the energy system through an expansion of variable renewable energy sources, such as wind and solar photovoltaic power production. This transition imposes new challenges to the electrical power system, not least from a power balance perspective. LÄS MER

7. 5. System impact of micro-production

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

   Författare :Annie Haraldsson; [2023]
   Nyckelord :Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

   Sammanfattning : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG. LÄS MER
