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. 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

4. 3. Study Of Universal Islanding Detection Techniques In Distributed Generation Systems

   Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

Method: This study develops a food waste mitigation framework based on a literature review and assess it through a case at a company. LÄS MER

7. 5. Congestion Management of EV Charging in Distribution Networks

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

   Författare :Adam Rosandell; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The societal integration of electric vehicles (EVs) imposes several challenges on the electrical grid, where congestion and overcurrents through related components are of focus for this thesis. Active network management through control systems is one flexible solution to this problem, and in the project Active Network Management for All (ANM4L), a congestion management algorithm utilizing PI controllers has been developed.
