1. 1. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating

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

   Författare :Ahmad Talaat Hifzy; [2023]
   Nyckelord :Floating; offshore; substation; transformer; GIS; equipment; high-voltage; fatigue; Flytande; havsbaserad; station; transformator; GIS; utrustning; högspänning; utmattning;

   Sammanfattning : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. LÄS MER

3. 2. Voltage Stability and Reactive Power - Introduction of Intermittent Renewable Energy Sources in a Power System

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

   Författare :Erik Hagström; Tobias Jansson; [2022]
   Nyckelord :Voltage Stability; Reactive Power; Renewable Energy; Wind Power; Power Flow Analysis; MATPOWER;

   Sammanfattning : The electricity demand increases rapidly, and in order to mitigate climate change the power production needs to be renewable and free from green house gas emissions. When solar and wind power are introduced in the system, voltage instability might become a problem. LÄS MER

4. 3. Optimal collection grid and transmission line topology for the grid connection of an offshore multi-source park.

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Alfred Nerby; [2022]
   Nyckelord :Renewable; Wind; Solar; multi-source; park; collection grid; substation; transmission; HVAC; HVDC; converters; shunt reactors; transformer; losses; CAPEX; OPEX;

   Sammanfattning : As spacial restrictions become more and more of an issue for renewable energy parks onshore, more developers are turning offshore to develop future production. The desire for a diversity of energy sources combined with a desire to utilize space efficiently has sparked an interest in renewable energy parks where more than one energy source occupy the space.

5. 4. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Hjörtur Brynjarsson; [2021]
   Nyckelord :Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

   Sammanfattning : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. LÄS MER

7. 5. Empirisk bestämning av nollföljdsimpedans hos transformatorer med utdragen deltalindning

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

   Författare :Carmen Dahlin; [2020]
   Nyckelord :;

   Sammanfattning : The main goal of the thesis is through available data, empirically determine the ratio betweenthe zero and positive-sequence impedance of different transformers with accessible-winding, i.e. when the -winding is loaded. LÄS MER
