  1. 41. Kartläggning av klimatarbete och klimatkrav i elnätsbranschen

    University essay from SLU/Dept. of Energy and Technology

    Author : Marcus Blomberg; [2022]
    Keywords : klimatpåverkan; elnät; offentlig upphandling; livscykelanalys; Green House gas protocol; scope 3;

    Abstract : The climate change is a growing issue that is put high up on the agenda for countries as well as businesses. In 2015 both EU and Sweden initiated joint initiatives to actively promote reduction of climate impact and stop the increase in global temperature. READ MORE

  3. 42. A Quality Assurance of NKT’s Temperature Measuring : Evaluation and Uncertainty Analysis of the Temperature Measuring Chain on High Voltage Cables

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Hannes Olausson; [2022]
    Keywords : Temperature; Uncertainty; Logger system; Thermocouple;

    Abstract : An overall increase of interest and need for high voltage cable have been acknowledge overthe last years. This is mainly due to the effect of the rapid expansion and transition fromfossil-energy sources to a future with non fossil-energy. READ MORE

  4. 43. First principles DFT study of polyethylene insulation containing chemical impurities - implementing counterpoise correction

    University essay from KTH/Tillämpad fysik

    Author : Max Pierre; [2022]
    Keywords : Applied physics; HVDC cable; Polymer physics; Polyethylene; Density functional theory; Molecular dynamics; CP2K; GROMAC; Electron traps; Band gaps; Density of states; Tillämpad fysik; HVDC kabel; Polymerfysik; Polyeten; Täthetsfunktionalteori; Molekulärdynamik; CP2K; GROMACS; Elektronfällor; Bandgap; Tillståndstäthet;

    Abstract : Density functional theory (DFT) calculations of polyethylene (PE) HVDC cable insulation have been performed for systems containing four different chemical impurities: acetophenone, cumene, $\alpha$-methyl styrene and $\alpha$-cumyl alcohol. Systems were generated by molecular dynamics (MD) equilibration at four different temperatures relevant for cable insulation applications: 277 K, 293 K, 343 K and 363 K. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  6. 45. A TECHNO-ECONOMIC FEASIBILITY STUDY OF OFFSHORE WIND-HYDROGEN PRODUCTION IN SOUTHERN SWEDEN

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Carol Hansson; [2022]
    Keywords : Wind Power; Hydrogen; Onshore; Offshore; Electrolysis; South Sweden; System; LCOE; LCOH; Subsidies; Grid connection; Case study; Techno-economic; Feasibility;

    Abstract :   To meet the energy targets and improve the lack of power and higher prices in southern Sweden, the amount of electricity must increase, and alternative fuel sources be introduced. This thesis examines the techno-economic feasibility of offshore wind-hydrogen production in southern Sweden, depending on whether an onshore- or offshore hydrogen system is used, and how grid connection subsidies would affect this.
