  1. 21. 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

  3. 22. ASSESSMENT OF WIND POWER PROJECTS: THE DEVELOPMENT OF A METHODOLOGY FOR EARLY-STAGE EVALUATION

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Ilya Ibraheem; [2023]
    Nyckelord :Wind Power; Wind power project management; MCDM; AHP;

    Sammanfattning : There is limited land accessible for the construction of wind farms due to the obstacles posed by geographical constraints, popular opposition, wildlife conservation, and power system integration. These variables make the planning of wind power projects a complex procedure requiring the consideration of numerous criteria and limits. LÄS MER

  4. 23. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework

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

    Författare :Niklas Barth; [2023]
    Nyckelord :Unsupervised Learning; Multivariate Time Series; Graph Convolutional Neural Networks; Anomaly Detection; Industrial Control System; EtherCAT; Power Station; Electricity Grid;

    Sammanfattning : In this thesis, an anomaly detection framework is assessed and fine-tuned to detect and explain anomalies in a power station, where EtherCAT, an Industrial Control System, is employed for monitoring. The chosen framework is based on a previously published Graph Neural Network (GNN) model, utilizing attention mechanisms to capture complex relationships between diverse measurements within the EtherCAT system.

  5. 24. Flexible Future : Exploring The Effects of Real Time Prices on Swedish Households’ Price Responsiveness

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

    Författare :Arvid Jonsson; Theo Målsten; [2023]
    Nyckelord :;

    Sammanfattning : The exceptionally high electricity prices in Sweden during 2022 changed the common view about electricity consumption and an increasing number of households switched from fixed or monthly contracts to real time price (RTP) contracts. Historically, there has been a limited amount of real user data on RTP customers and their consumption behaviors. LÄS MER

  7. 25. 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
