  1. 1. Variation Management Strategies for Future Construction Sites: A study to address role of an equipment rental business in the energy transition

    H-uppsats,

    Författare :Ellen Blanksvärd; Frida Svensson; [2023-09-21]
    Nyckelord :battery storage; variation management; flexibility services; peak shaving; load shifting; demand side management; rental business; electrification; construction equipment; construction sites;

    Sammanfattning : Construction sites are facing challenges with high power peaks due to electrificationof heavy equipment where potential consequences are increased power tariffs locallyand risk of limited power supply. Another development is an increased intermittentpower supply due to more wind- and solar power in the electricity system, whichcauses price fluctuations. LÄS MER

  3. 2. Hosting Capacity Methods Considering Complementarity between Solar and Wind Power : A Case Study on a Swedish Regional Grid

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Emma Andersson; Maja Abrahamsson Bolstad; [2023]
    Nyckelord :hosting capacity; hosting capacity methods; renewable power generation; power grid; power system analysis; complementarity; solar power; wind power; deterministic method; time series method;

    Sammanfattning : The demand for electrical power is growing due to factors such as population growth, urbanisation, and the transition from fossil fuels to renewable energy sources. To be able to keep up with the changes in electricity demand, the Swedish power grid must connect more renewable power generation, but also  increase its transmission capacity. LÄS MER

  4. 3. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Umar Farooq; [2023]
    Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

  5. 4. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Simon Garpenquist; [2023]
    Nyckelord :Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

    Sammanfattning : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. LÄS MER

  7. 5. Techno-economic analysis of Energy Storage as a Service business models for prosumers in France

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

    Författare :Alice Lacroix; [2023]
    Nyckelord :;

    Sammanfattning : One of the current challenges for developed countries is the transformation of the entire electricity system. Ambitious objectives of renewable energy penetration in the electricity mixare established to reduce the energy sector’s greenhouse gas emissions rate and reach sustainability goals. LÄS MER
