  1. 1. Future-competing battery chemistries for large-scale energy storage

    Master-uppsats, KTH/Kemiteknik

    Författare :Erik Adolfsson; [2023]
    Nyckelord :Battery energy storage systems; Nickel-hydrogen battery; Zinc-bromide flow battery; Iron-air battery; Large-scale applications; Batterier för energilagringssystem; Nickel-vätgasbatteri; Zink-brom flödesbatteri; Järn-luftbatteri; Storskaliga användningsområden;

    Sammanfattning : ’Netto-noll utsläpp’ i EU vid 2050 är ett av målen för att påskynda övergången från fossila bränslen till mer förnyelsebara och hållbara alternativ. Detta har däremot introducerat mer turbulens på elnäten. LÄS MER

  3. 2. Optimering av en flytande vindkraftspark

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Mattias Blavier; Elin Granath; Emelie Jin; Elin Johansson; Axel Svensson; Kristina Thylin; [2023]
    Nyckelord :Vindkraft; flytande vindkraft; simulering; modellering; optimering; AEP; LCOE;

    Sammanfattning : This paper presents a study on the optimization of floating offshore wind farms. The aim of this study is mainly to create a tool that can help determine the most profitable layout option for the floating offshore wind power company Windeed. LÄS MER

  4. 3. Energy flows and potential energy development strategies in RoRo ports: A study based on the Port of Trelleborg

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Gabriele Gonzales; [2023]
    Nyckelord :RoRo Ports; Energy Flows; Energy Development; Energy Strategies; Renewable Energy; Ports; Energy Hub; Energy Storage; Hydrogen; Technology and Engineering;

    Sammanfattning : The recent push for decarbonization in the maritime sector presents an opportunity for ports to strengthen their position as energy hubs. This work studies the existing energy flows in the Port of Trelleborg, one of Europe's biggest roll-on, roll-off ports, and proposes some energy-related development strategies. LÄS MER

  5. 4. Resonant overvoltages caused by transformer energization and saturation : Two EMT case studies conducted using models of the grid in Stockholm and an off-shore wind farm

    Master-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Gustav Sundberg; [2021]
    Nyckelord :Resonant overvoltages; Resonance frequency; Parallel resonance; EMT studies; Transformer saturation; Off-shore wind power; Inrush current; Sympathetic Inrush; Resonanta överspänningar; Resonansfrekvens; Parallellresonans; EMT-studier; Magnetiseringsström; Havsbaserad vindkraft;

    Sammanfattning : This thesis investigates the impact of resonant overvoltages and their origin. Series and parallel resonances are present in any electrical grid. The frequency of which this resonance occurs is called resonance frequency. LÄS MER

  7. 5. Centrifugal Turbopumps - Flow Physics and Modelling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Carl Eriksson; Hampus Henåker; [2021]
    Nyckelord :Centrifugal Pumps; Rocket Science; Turbopumps; Two-Zone Model; Impeller; Vaneless Diffuser; Vaned Diffuser; Technology and Engineering;

    Sammanfattning : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. LÄS MER
