  1. 1. Forecasting of Heat Pump Power Consumption using Neural Networks

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Gustav Warnström; Johan Fant; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With the increase in electricity generation from renewable sources over recent years, the demand for ancillary services providing balancing support in the grid has risen. Demand side regulation can be performed by regulating consumption of some household devices, which can act as a virtual battery that can be loaded and unloaded into the grid. LÄS MER

  3. 2. Modelling and Investigation of Control of a Power Infrastructure Resource Management System for a Radio Base Station : A study on sustainable power management for ICT infrastructure.

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

    Författare :Gustav Lenart; [2023]
    Nyckelord :Hybrid Dynamical Systems; Resource Management; Hybrid Automaton; Sustainable solutions for Wireless technology; Hybrid Dynamiska System; Resurshantering; Hybrid Automaton; Hållbara lösningar för trådlös teknologi;

    Sammanfattning : In order to minimize greenhouse gas emissions and operational cost related to the ICT-infrastructure the power management method of a Radio Base Station (RBS) or Base Transceiver Station (BTS) at Ericsson is studied and modelled. The major load demand at RBS’s are due to uplink and downlink data traffic. LÄS MER

  4. 3. Influence of current harmonics on the degradation of the catalyst coated membrane in PEMFC

    Master-uppsats, KTH/Kemiteknik

    Författare :Evelina Ahlén Norberg; [2022]
    Nyckelord :Proton Exchange Membrane Fuel Cell; Ripple Current; Current Harmonics; Degradation; Marine transportation; Polymerelektrolytbränslecell; Rippelström; Strömoscillation; Åldring; Sjötransport;

    Sammanfattning : Sjöfarten är idag dominerad av förbränningsmotorer som är beroende av fossila drivmedel. Elektrifiering är en av huvudstrategierna för att möjliggöra fossilfri energiförsörjning inom internationell sjöfart. LÄS MER

  5. 4. Electric conversion of combustion engine cars

    M1-uppsats, KTH/Hållbar produktionsutveckling (ML)

    Författare :Annika Modling; Bobby Åbrandt; [2022]
    Nyckelord :Electric conversion; combustion engine; electric motor; lithium-ion; lead-acid; DIY; second hand; Elkonvertering; förbränningsmotor; elmotor; litiumjon; blysyra; DIY; begagnat; cirkulär process;

    Sammanfattning : The electrification of personal transport vehicles is one of the strategies to counteract global warming and dependance on fossil fuels. Diesel powered cars are already prohibited in several big cities and the prices for fuel are constantly climbing. LÄS MER

  7. 5. Shielding of Transformer Stray Fields in Trains

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

    Författare :Lárusdóttir Lára Ólafia; [2022]
    Nyckelord :;

    Sammanfattning : Generally, a transformer will produce stray magnetic fields. Aboard trains, the transformer’s stray fields can pose problems to other components inside or outside the train. Further, regulations require the magnetic field to be below certain levels in the passenger area. LÄS MER
