    Sammanfattning : The transition in the transport sector by the integration of battery electric vehicles (BEVs) brings a new challenge for the system operators to ensure the balance between supply and demand. The installation of new EV charges poses a surge in electricity demand in the coming years which jeopardizes the grid reliability and stability. LÄS MER

  4. 3. Energy Storage for Voltage Control in LV Grids

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

    Författare :Ida Samnegård; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis addresses overvoltage issues in weak low voltage grids caused by large solar power production. The suggested method is using PI controllers to control voltage. This is done by using battery energy storage systems (BESS), designed to absorb active power during these times and thereby limiting the voltage rise. LÄS MER

    Sammanfattning : Sweden has a goal of becoming carbon neutral by 2045. To reach this goal electrification of different sectors are one of the most important pathways for becoming fossil free. The power grid in Sweden has historically been seen as stable and with unlimited transmission capacity. LÄS MER

  7. 5. Artificial Intelligence in rural offgrid Polygeneration Systems: : A Case Study with RVE.Sol focusing on Electricity Supply & Demand Balancing

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

    Författare :Axel Bruck; [2019]
    Nyckelord :;

    Sammanfattning : Growing data generation and increasing computational power accelerate the advance of machine learning (ML) as a subsection of artificial intelligence in various sectors, while in Sub-Saharan Africa (SSA) electrification cannot keep up with the pace of population growth. Hence, this study aims to determine how ML can support rural polygeneration minigrids and thus assisting the electrification efforts in SSA in cooperation with the company RVE. LÄS MER
