  1. 1. Planning and Operation of Demand-Side Flexibility

    Författare :Meng Song; Mikael Amelin; Alessandra Parisio; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Power systems are changing with growing penetration of non-dispatchable renewable generation and increased demand of electric energy. More generation, transmission or distribution capacities are needed to balance the varying production and higher consumption. Demand-side flexibility is a potential solutionto tackle those challenges. LÄS MER

  3. 2. Energy consumption transition : final household energy consumption in the case of Sweden 1920-2010

    Författare :Mikael Levin; Lars-Fredrik Andersson; Ann-Kristin Bergquist; Thomas Pettersson; Bengt Kriström; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic history; households; energy transition; energy consumption; residential; electrical appliances; Carbon dioxide; emission; ekonomisk historia; Economic History;

    Sammanfattning : This licentiate thesis examines households’ final energy consumption over the long run by measuring their final energy use and examining how structural, institutional and economic factors affected the demand for energy in the residential sector during the period 1920-2010, a period covering the transition from traditional to fossil to renewable energy carriers. I believe that wider understanding of the historical energy transition and energy consumption within the residential sector might help us gain important insights into the long-run development and the factors affecting energy consumption among the households.

  4. 3. Electrical Characterization of Metal-Oxide-Silicon Structures with Ultra Thin Oxide Layers

    Författare :Per Lundgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunneling; MTOS; oxide defects; MOS; PMA;

    Sammanfattning : Metal-oxide-semiconductor (MOS) structures with very thin (2 - 4 nm) oxide layers thermally grown on silicon have been electrically characterized regarding oxide and interface defects and concerning the direct tunnel current through the oxide. This thesis comprises eight papers which deal with the appearance of oxide charge during electrical stress (papers A, D, E), the beneficial effect on the defect density of low-temperature (up to 350 °C) post-metallization annealing (PMA) (paper A, B, C, G), and the effect of temperature and choice of metal for the tunnel current (paper F, H).
