  1. 1. Design of a Future Residential DC Microgrid

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Viktor Andersson; Max Gugolz; [2022]
    Keywords : Grid control; grid converter; DC microgrid; buck-boost; PV; MPPT; P O; ESS; SOC;

    Abstract : In the search for environmentally friendly methods to implement renewable energy in the power system residential microgrids have been proposed and proven. The direct current (DC) microgrid topology is a promising implementation of a microgrid system due to the increasing amount of DC-operated loads and production units expected in the near future.

  3. 2. Development of Foot Design for Gasketed Plate Heat Exchangers

    University essay from Lunds universitet/Innovation

    Author : Daniel Rundström; [2022]
    Keywords : Heat exchanger; bolted joints; product development; FEM.; Technology and Engineering;

    Abstract : In the process of making the industry more energy efficient, the gasketed plate heat exchanger has an important role as it effectively transfers heat between fluids. This master thesis aims to investigate and develop a new supportive foot for Alfa Laval’s gasketed plate heat exchangers. READ MORE

  4. 3. The effect of reinforcement configuration on crack widths in concrete deep beams

    University essay from KTH/Betongbyggnad

    Author : Rahimeh Hosseini; Anita Nolsjö; [2017]
    Keywords : crack widths; crack development; conventional beams; deep beams; reinforcement stress; tenslie- and crack reinforcement; minimum reinforcement; reinforcement configuration; external loads; non-linear analysis; sprickvidder; ordinära balkar; höga balkar; armeringsspänning; kraft- och sprickarmering; minimiarmering; armeringsutformning; externa laster; icke linär analys;

    Abstract : Reinforced concrete deep beams are known for applications in tall buildings, foundations and offshore structures. Deep beams are structural elements with length and height within the same magnitude and have significantly smaller thickness compared to a conventional concrete beam. READ MORE

  5. 4. Turbulence Intensity in Complex Environments and its Influence on Small Wind Turbines

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Nicole Carpman; [2011]
    Keywords : turbulence intensity; complex; uniform; small wind turbines; IEC standard classes; normal turbulence model; turbulensintensitet; komplex; homogen; urban; små vindkraftverk; IEC standard klasser; normal turbulensmodell;

    Abstract : The market of wind power as a sustainable energy source is growing, both on large and small scale. Conventional large scale wind turbines normally operate in uniform areas where expected wind speeds and turbulence characteristics are well investigated and the constructional design of the wind turbines is regulated by standard classes for different external conditions.
