  1. 1. Evaluation of the challenges and opportunities of Vehicle-to-Grid technology and the potential revenue streams for BEV fleet owners and aggregators

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

    Författare :Lukas Strandberg; Madeleine Sandberg; [2023]
    Nyckelord :Vehicle-to-Grid; Grid flexibility; Capacity markets; Barriers; Fordon-till-nätteknologi; Elnätsflexibilitet; Kapacitetsmarknader; Barriärer;

    Sammanfattning : The increasing amount of renewable energy being connected to the power grid, and the intermittent nature of these resources, calls for increased grid flexibility to ensure operational safety and stability. An effective solution to address this need could be through wider implementation of various energy storage technologies. LÄS MER

  3. 2. The Impact of an Offshore Wind Farm on a Power Grid

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Arvid Söderberg; Tim Possekel; [2023]
    Nyckelord :;

    Sammanfattning : Due to increasing power demands and growing importance of sustainability, more and morewind power is being built and connected to existing power systems. While wind power isboth renewable and cost-effective, it is important to note that due to its variable nature, itcan negatively impact the stability of a power system. LÄS MER

  4. 3. Network reconfiguration for renewable generation maximization

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Gabriel Malmer; Lovisa Thorin; [2023]
    Nyckelord :distributed generation; hosting capacity; network reconfiguration; optimal power flow; power distribution; optimization; mixed-integer programming; Technology and Engineering;

    Sammanfattning : Increasing the amount of renewable generation in distribution networks is a fundamental part of the energy transition. Multiple methods exist to increase the hosting capacity in a grid, to allow larger injections of generation and more efficiently utilize existing infrastructure before operational limits are breached.

  5. 4. Short-horizon Prediction of Indoor Temperature using Low-Order Thermal Networks : A case study of thermal models for heat-system control applications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jonas Cederberg; [2023]
    Nyckelord :Lumped Parameter Thermal Network; Resistance-Capacitance model; Parameter estimation; Modelling of Dynamical Systems; Thermal modelling; Temperature Prediction; Termiskt nätverk med klumpade parametrar; Mostånds-kapacitans modell; Parameterestimering; Modellering av dynamiska system; Termisk modellering; Temperaturprediktion.;

    Sammanfattning : Optimizing and controlling the heating systems in buildings is one way to decrease their load on the power grid, as well as introduce load flexibility to be used in Demand Response (DR) applications. A requirement in occupied buildings is that the thermal comfort of the residents is guaranteed, making the optimization of heating systems a constrained problem with respect to indoor temperature.

  7. 5. Fast charging of electrical vehicles with help from battery energy storage systems : A study of how batteries can lower the power peaks for fast charging of electrical vehicles in Stockholm

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Erik Wikström; [2023]
    Nyckelord :Electric vehicle; fast charging; direct current charging; battery energy storage system; Elfordon; snabbladdning; likströmsladdning; batterienergilagringssystem;

    Sammanfattning : To enable fast charging of electric vehicles in Stockholm or sites where the electrical energy is limited and the number of chargeable vehicles increases, there is a need to investigate new solutions to comply with the future demand. The goal of this project is to investigate what the conditions are in Stockholm today and investigate what is needed to enable fast chargers in Stockholm city. LÄS MER
