  2. 2. The impact on the energy system of heating demands in buildings : A case study on district heating and electricity for heating in Falun, Sweden

    Författare :Moa Swing Gustafsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Forests and Built Environments; Energi; skog och byggd miljö;

    Sammanfattning : Energy efficiency measures in buildings are considered to have great potential in order to reduce total energy consumption, and thus contribute to a reduced environmental impact and a better climate. In Sweden, however, the energy performance requirements for buildings are formulated in terms of bought energy, i.e. LÄS MER

  3. 3. Heating of buildings from a system perspective

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Moa Swing Gustafsson; Erik Dotzauer; Jonn Are Myhren; Tomas Ekvall; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Energy efficiency measures in buildings are considered to have great potential for reducing total energy use, and contribute to a reduced climate and environmental impact. In Sweden, however, there is a focus on bought energy, which does not always reflect the environmental and climate impact. LÄS MER

  5. 5. Power System Oscillations - Detection, Estimation and Control

    Detta är en avhandling från Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Författare :Morten Hemmingsson; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER
