  1. 1. Centralised MPC for Long-term Voltage Stability Control of Power System

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

    Författare :Johan Hallberg; [2023]
    Nyckelord :Voltage stability; Model predictive control; Tap-changing transformer; Capacitor bank; Spänningsstabilitet; Model prediktiv reglering; Lindningskopplare; Kondensatorbank;

    Sammanfattning : In a power system it is important to keep voltages at specific levels at network buses. Deviations from that can lead to reduced efficiency of transferred power or, in more severe cases, widespread power outages affecting large parts of society. There exists a variety of power system devices that have the ability to regulate the voltage levels. LÄS MER

  3. 2. Reactive power compensation of the electricity grid with large-scale offshore wind farms in Sweden : Technical capabilities, grid codes and economic incentives

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Agnes Bråve; Sara Särnblad; [2022]
    Nyckelord :Wind power; offshore wind farm; reactive power; reactive power market; grid code; RfG; voltage stability; Vindkraftspark; havsbaserad vindkraft; reaktiv effekt; reaktiv effektmarknad; nätkod; spänningsstabilitet;

    Sammanfattning : Year 2040 the goal is to have a 100 % renewable Swedish energy system. Svenska kraftnät (Svk) predicts fully decommissioned nuclear power plants and an increased amount of connected wind power plants, especially offshore, year 2045. LÄS MER

  4. 3. Voltage Stability and Reactive Power - Introduction of Intermittent Renewable Energy Sources in a Power System

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

    Författare :Erik Hagström; Tobias Jansson; [2022]
    Nyckelord :Voltage Stability; Reactive Power; Renewable Energy; Wind Power; Power Flow Analysis; MATPOWER;

    Sammanfattning : The electricity demand increases rapidly, and in order to mitigate climate change the power production needs to be renewable and free from green house gas emissions. When solar and wind power are introduced in the system, voltage instability might become a problem. LÄS MER

  5. 4. Sustainable Implementation of Photovoltaic Technologies in Mauritius : A study on the energy system in Mauritius and the effect of solar power generation on frequency stability

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Maria Isabel Bang Jensen; Simon Lundberg; [2020]
    Nyckelord :Isolated energy system; photovoltaic technologies; frequency stability; system inertia; grid readiness; renewable energy; sustainable energy mix; Mauritius; PV shutdown; N-1 security; Isolerad energisystem; solceller; frekvensstabilitet; svängmassa; förnybar energi; hållbar energimix; Mauritius; produktionsbortfall; N-1 säkerhet;

    Sammanfattning : Mauritius is an isolated island with ambitious targets for renewable energy generation and plans to invest in more solar power. The aim of this study is to assess how the implementation of photovoltaic technologies might affect the frequency stability in Mauritius and thus assess whether solar power can help the country obtain their targets for green energy generation.

  7. 5. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Mohammadjavad Javadi; [2020]
    Nyckelord :Corona discharge; Suppression ring; High voltage capacitor banks;

    Sammanfattning : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.
