  1. 16. Optimering av ett batterilager i kombination med ett större solcellssystem : Fallstudie: Gävle Energi ABs huvudbyggnad

    Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Carolina Johansson; [2020]
    Nyckelord :Effekttoppsreducering; frekvensreglering; batterilager; nätansluten fastighet; solcellssystem;

    Sammanfattning : The increase of variable renewable source leads to an imbalance between the electricity supply and demand of the power grid, as the solar and wind energy production is weather dependent. By implementing battery energy storage system (BESS), the balance can be improved by storing energy when the supply is high and then use when the supply is low. LÄS MER

  3. 17. Understanding Value in Frontier Technology Environments : A case study on indoor air quality and HVAC systems

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Gerardo Gallegos Castillo; [2020]
    Nyckelord :Value; Business-to-Business; Indoor Air Quality; Sustainability; HVAC Systems;

    Sammanfattning : Business dynamics have generally been driven by the ability to create and provide value to customers. Value has evolved over time having meanings from merely price to something that actually creates a competitive advantage. LÄS MER

  4. 18. Enabling More Efficient E-Mobility : Grease Development by a Novel Bearing-Grease Test Machine

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Gabriel Benjamin Calderon Salmeron; [2019]

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

    Författare :Rudolf Kerekes; [2019]
    Nyckelord :;

    Sammanfattning : The need for energy storage solutions became more significant with the increasing penetration of renewable energy sources in the electricity grid. In the last decades, the flow batteries have gained increasing attention. They have several advantages compared to the conventional battery technologies. LÄS MER

  7. 20. Towards sustainable renovation of façades : A case study of additional double glass façade on lamella house from energy saving perspective

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Yang Shi; [2019]
    Nyckelord :renovation; façade; Million Programme; IDA ice; Trombe wall; double glass façade; sustainability;

    Sammanfattning : The pace of development in modern society since the Industrial Revolution has beenunprecedented and it keeps proceeding in a more aggressive and accelerated phase. However, thisdevelopment is a highly energy demanded action which is resulting an increased exploitation ofnatural resources, and subsequently, an expanded pressure on our environment, which sometimesconflicts between proprietors.
