  1. 1. Local voltage control in a low voltage grid with high photovoltaic penetration

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Joakim Bakklund; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

  5. 4. Analys och vidareutveckling av simuleringsmiljö för LFC-reglering inom NBM-programmet

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Marcus Baumann; [2023]
    Nyckelord :Load frequency control; Power system simulator; Nordic Balancing Model; ARISTO;

    Sammanfattning : The control and balancing measures for achieving safe grid operation in the Nordic power grid is becoming increasingly complex with larger penetrations of renewable power, new guidelines aiming to increase digitalisation and automation alongside integration into European balancing platforms. The power grid operators are faced with new challenges for safely operating the grid leading to an increased need for theoretical and practical education. LÄS MER

  7. 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
