1. 1. Parallel Operation of Grid-Forming Power Inverters

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Alessia Camboni; [2023]
   Nyckelord :;

   Sammanfattning : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. LÄS MER

   Sammanfattning : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. LÄS MER

4. 3. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Abdullah Albalali; [2022]
   Nyckelord :energy storage; frequency control; synchronous generators; distributed power generation; virtual synchronous machine VSM ; PSCAD.; energilagringssystem; frekvenskontroll; synkrona generatorer; distribuerad kraftproduktion; virtuell synkron maskin; PSCAD.;

   Sammanfattning : The modern power system is aiming to progress away from conventional synchronous machine  based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).

5. 4. Simplified Model For Simulation of Fault Ride Through at Hydropower Units

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Sebastian Söderström; [2021]
   Nyckelord :Fault Ride Through; Hydropower; Simulation; Generator; Simulink; Transient Stability; Gränsbryttid; Vattenkraft; Simulering; Generator; Simulink; Transient Stabilitet;

   Sammanfattning : As new requirements for grid connected generators were implemented, the requirements for evaluating the Fault Ride Through capabilities of the generators became stricter. When refurbishing a power unit, proof that the power unit meet the requirements must be submitted to the authorities. LÄS MER

7. 5. Excitation system – simulation, tuning and evaluation

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Philip von Heideken; [2021]
   Nyckelord :;

   Sammanfattning : Swedish Electrical and Power Control AB (Svea Power) offers excitation systems for electrical production plants. An excitation system controls the electrical performance of the generator’s three phase outputs and must meet requirements set out in the business agency “Svenska Kraftnäts (SvK:s) föreskrifter, SvKFS 2005:2”.
