  1. 1. Importance of the demand-supply balance in district heating systems

    Författare :Dmytro Romanchenko; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility; Space heating; demand response; buildings; optimisation; thermal energy storage; district heating;

    Sammanfattning : In line with global efforts directed against climate change, the building sector will have to undergo significant changes in terms of its energy use, along with the transformation of the energy system. The scope of this thesis is limited to the energy supply and demand within district heating (DH) systems, with the emphasis on the space heating demand in buildings. LÄS MER

  3. 2. Buildings as thermal energy storage – Pilot test and large-scale implementation for district heating systems

    Författare :Johan Kensby; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space heating; Heat load; Heat demand; District heating; Thermal energy storage; Demand side management; Buildings;

    Sammanfattning : Heat loads in a district heating system can exhibit significant variations within a single day, which sets problematic conditions for efficient heat generation. Short-term thermal energy storage (TES) can decrease these daily variations and make the conditions for generating heat more favorable. LÄS MER

  4. 3. The future load curve of the Swedish building stock – Interactions between the heating load and district heating

    Författare :Dmytro Romanchenko; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; District heating; demand response; buildings; optimisation; space heating;

    Sammanfattning : In line with global efforts directed against climate change, the building sector is required to undergo significant changes in terms of its energy management. This is the case for both the use of energy (reduced energy consumption) and the supply of energy (heat and electricity), and how these two interact. LÄS MER

  5. 4. Power to the people : electricity demand and household behavior

    Författare :Mattias Vesterberg; Runar Brännlund; Chandra Kiran Krishnamurthy; Maximilian Auffhammer; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; electricity demand; real-time pricing; demand flexibility; elasticity; appliance-level data; end-use; media; contract choice; de-regulated market; household behavior; intermittent electricity production; efficiency; imperfect information;

    Sammanfattning : Paper [I] Using a unique and highly detailed data set on energy consumption at the appliance-level for 200 Swedish households, seemingly unrelated regression (SUR)-based end-use specific load curves are estimated. The estimated load curves are then used to explore possible restrictions on load shifting (e.g. LÄS MER

  7. 5. Effektivisering av pump- och fläktdrifter i byggnader. Elanvändning och systemlösningar

    Författare :Caroline S Markusson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; damper; efficiency; electric energy; authority; demand; control; variable speed; valve; heating; cooling; fans; electric motors; ventilation; pumps;

    Sammanfattning : In this licentiate work the energy savings potential by more efficient pump and fan operation in buildings has been examined. The national savings potential in Sweden has been estimated based on available statistics and on information gained in a limited inventory. The estimated energy use for pump operation in residential and commercial (i.e. LÄS MER
