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)

   Nyckelord :Distributed Generation; Islanding; Quality Factor; Resonance Frequency; Low Voltage; Medium Voltage; Electronic Power Converter; Inverter;

   Sammanfattning : Energy security, global warming, and climate change have been a major source of global discussions and development. Likewise, the rising cost of electricity for consumers and exponential demand for energy are major factors driving the incremental growth and integration of sustainable forms of energy generation into power the system cycle.

   Sammanfattning : The presence of electric vehicles (EVs) in the passenger car fleet has increased at a rapid rate and the development is predicted to continue in the same direction. The charging of these vehicles predominantely takes place in the owners’ homes and thus increases the households’ demand for electricity - both in terms of the amount of energy and the size of power peaks.
