  1. 16. Unlocking the Potential of Battery Energy Storage Systems in the Nordic Frequency Regulation Markets : A techno-economic analysis to evaluate long-term profitability

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

    Författare :Theodor Ingman; Henrik von Sivers; [2023]
    Nyckelord :;

    Sammanfattning : As the Swedish power system has increased its shares of production coming from intermittent renewables, the production coming from large rotational units as nuclear, and hydropower, has decreased. Thereby, the power system has become more sensitive to sudden changes between production and consumption of electricity, increasing the risk of disruptions in the electricity grid. LÄS MER

  3. 17. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Natachai Terawatsakul; [2023]
    Nyckelord :;

    Sammanfattning : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. LÄS MER

  4. 18. Oral contraceptive phases and performance : Strength, anaerobic capacity, and lactate responce

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Isa Rönneblad; Elsa Ohrås; [2023]
    Nyckelord :Performance; oral contraceptive; contraception; Wingate; IMTP; anaerobic capacity; strength; percieved energy level; lactate; prestation; p-piller; preventionsmedel; anaerob förmåga; styrka; upplevd energinivå; laktat;

    Sammanfattning : Background: Oral contraceptives are common among female athletes. Still, its effects on athletic performance are poorly investigated. Research in the area has increased in recent years. However, the study qualities and designs are often insufficient and with small sample sizes. LÄS MER

  5. 19. Analys av platinaytor och platinatennytor under katalytisk etanoloxidation med röntgenfotoelektronspectroskopi

    Magister-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Mats Viktor Löfstrand; [2023]
    Nyckelord :Pt3Sn; APXPS; Ethanol oxidation; Pt 111 ; Pt 223 ;

    Sammanfattning : Fuel cells are more efficient and cleaner than combustion engines. Ethanol as a fuel has a high energy density and is safer and easier to handle than hydrogen which is normally used in fuel cells. If efficient fuel cells on alcohol were available, they could be used for engines and power sources for electronics. LÄS MER

  7. 20. Flexibilitetsåtgärder i uppvärmningssystemet: En undersökning om hur implementering av flexibilitetsåtgärder i uppvärmningssystemet kan reducera uppvärmningskostnaden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Marcus Lundström; [2023]
    Nyckelord :flexibilitetstjänster; livscykelkostnader; värmelager; värmepump;

    Sammanfattning : In 2022, Sweden faced significant challenges in its energy landscape due to a combination of factors, including Russia's invasion of Ukraine, domestic disruptions in nuclear power production, low water reservoir levels, and the increasing reliance on intermittent energy sources. Consequently, the price of electricity in Sweden soared to unprecedented levels. LÄS MER
