  1. 1. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

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

    Författare :Doris Dijak; Elin Torstensson; [2023]
    Nyckelord :Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

    Sammanfattning : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

  4. 4. Analysing the effects of 24/7 Carbon-free Energy procurement strategies on the electricity system : Case Study of commercial and industrial sector in the Netherlands

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

    Författare :NINA JABŁOŃSKA; [2023]
    Nyckelord :24 7 Carbon-free Energy; carbon accounting; corporate electricity procurement; Energy Attribute Certificates; hourly matching; the Netherlands.; 24 7 kolfri energi; koldioxidredovisning; företagens elupphandling; energiattributcertifikat; timmatchning; Nederländerna.;

    Sammanfattning : Considering the growing importance of the electricity sector in the worldwide decarbonisation efforts, as well as large volumes of energy consumed by the commercial and industrial (C&I) sector, corporate power procurement is found to be a significant contributor to building a net zero economy. Within this topic, hourly matching of carbon-free electricity supply with demand, or 24/7 Carbon-free Energy (24/7 CFE), is identified as a next-generation power procurement framework, with growing interest from a wide range of stakeholders in the energy sector and benefits backed by robust research evidence.

  5. 5. Minimising Battery Degradation And Energy Cost For Different User Scenarios In V2G Applications : An Integrated Optimisation Model for BEVs

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Jacob Bengtsson; Benjamin Moberg Safaee; [2023]
    Nyckelord :Vehicle-to-Grid; V2G; Battery Electric Vehicle; BEV; State-of-Charge; SoC; State-of-Health; SoH; charging; discharging; degradation; energy cost; optimisation; optimization; Pyomo; Gurobi;

    Sammanfattning : The functionality to both charge and discharge energy from and to the power grid to a Battery Electric Vehicle (BEV) is referred to as Vehicle-to-Grid (V2G). This allows the customer to buy energy when the spot price is low and sell energy when the price is high to make a profit, called energy arbitrage. LÄS MER
