  4. 3. Model Predictive Control for Ground Source Heat Pumps : Reducing cost while maintaining comfort

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Isak Bokne; Charlie Elf; [2023]
    Nyckelord :MPC; Model Predictive Control; heat pump control; electricity spot price; weather prediction; reducing cost;

    Sammanfattning : Today, the control of heat pumps aims to first and foremost maintain a comfortable indoor temperature. This is primarily done by deciding input power based on outside temperature. The cost of electricity, which can be rather volatile, is not taken into account. LÄS MER

  5. 4. HEAT CONSUMPTION OPTIMIZATION IN 4TH GENERATION DISTRICT HEATING : Study on utilizing low temperature heat sources and heat stored in a house by varying indoor temperature

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Framtidens energi

    Författare :Simon Karlsson; Farman Farman; [2023]
    Nyckelord :4th Generation District Heating; Heat Pumps; Thermal Energy Storage; Optimization; Low Temperature Heat Sources; Thermal Inertia;

    Sammanfattning : 4th generation district heating (4GDH) and varying the indoor temperature to store heat are both important concepts that can make it easier to implement more renewable energy and reduce costs of heating. This study looks at these concepts from a customer perspective using one building and looking at how energy can be stored and the performance of 4GDH. LÄS MER

  7. 5. Potential benefits of implementing demand response into Vattenfall’s district cooling grid in Uppsala, Sweden

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

    Författare :Magdalena Guerrero Wretljung; [2023]
    Nyckelord :;

    Sammanfattning : Lately, there has been an increased cooling demand in Vattenfall’s district cooling (DC) network in Uppsala, Sweden. This especially occurs on warmer summer days, during so-called peak demand periods, where there is limited cooling capacity combined with limited distribution capacity in the network. LÄS MER
