    Sammanfattning : In 2022, Sweden faced significant challenges in its energy landscape due to a combination of factors, including Russia's invasion of Ukraine, domestic disruptions in nuclear power production, low water reservoir levels, and the increasing reliance on intermittent energy sources. Consequently, the price of electricity in Sweden soared to unprecedented levels. LÄS MER

  7. 5. 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
