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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Arvid Söderberg; Tim Possekel; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Decentralizing electricity generation in Cuba : Implementation of a microgrid in the sugar mil lCarlos Baliño

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Aylin Berber; Cornelia Eriksson; [2023]
    Keywords : Microgrid; renewable energy; bagasse; self-sufficiency; Microgrid; förnybar energi; bagass; självförsörjande;

    Abstract : Cuba has a long history of different dependencies and is a country facing many energy challenges, and therefore seeks to diversify its energy sources and reduce its reliance on fossil fuels. The purpose of this degree project is therefore to conceptualize a microgrid based on renewable energy sources for local energy sustainability at the lowest cost possible. READ MORE

  4. 3. Frequency Stabilization in low Inertia Systems With Battery Power Injections

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Leif Lundin; [2023]
    Keywords : ;

    Abstract : The challenges for the power system of the future becomes increasingly larger when large amountsof renewable energy sources are integrated, and when conventional forms of power such asnuclear power are phased out. This results in a greater difficulty in quickly deploying FrequencyContainment Reserves in the event of of power balance disturbance, to stabilize frequency andvoltage. READ MORE

  5. 4. Towards a Stochastic Operation of Switzerland’s Power Grid

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alban Maury; [2023]
    Keywords : Monte-Carlo simulations; probabilistic forecasting; copula theory; power flow analysis; Monte Carlo-simuleringar; probabilistiska prognoser; kopulateori; analys av energiflöden;

    Abstract : As Europe’s power production becomes increasingly reliant on intermittent renewable energy sources, uncertainties are likely to arise in power generation plans. Similarly, with the growing prevalence of electric vehicles, electric demand is also becoming more uncertain. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE
