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. Analysis of synthetic inertia using wind turbines for frequency stability in power systems

   Kandidat-uppsats, Lunds universitet/Industriell elektroteknik och automation

   Författare :Carl Herrlin; [2022]
   Nyckelord :Synthetic inertia; wind turbines; energy systems; electrical power; Technology and Engineering;

   Sammanfattning : With the large expansion of renewable energy sources such as wind- and solar, the stability and quality of electrical power can be affected. The transition towards large-scale wind power offers many opportunities to maintain stability by using power converters to create synthetic inertia. LÄS MER

5. 4. Grid Scale Storage Placement In Power Systems

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Andreas Bodegård; [2022]
   Nyckelord :FFR; frequency regulation; PowerFactory; DIgSILENT; grid scale storage; inertia; power system; rotor-angle stability; frequency stability; modal analysis; kundur two area model; nordic32;

   Sammanfattning : The increasing amount of renewable energy sources is applying more and more pressure on today’s power system. Additionally, plannable sources of energy, which are mostly non-renewable, are being decommissioned at a high rate to combat climate change. LÄS MER

7. 5. Wind Farm Modeling in DIgSILENT PowerFactory® and Load Flow Analysis of Internal Collector Network

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Lakshitha Daham Makewita; [2022]
   Nyckelord :Wind Farm Internal Collector Network; Active Power Loss; Cable Loading;

   Sammanfattning : The purpose of this study is to model an operational wind farm in DIgSILENT PowerFactory® using manufactures specifications and investigate the active power energy losses. The model is tested with the operational recorded data from the wind farm and is validated. LÄS MER
