  1. 1. Local Voltage Control in Converter Based PV Generation

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

    Författare :Charlotta Sporre; [2024]
    Nyckelord :distributed generation; active network management; low voltage distribution network; delta control; voltage control; Technology and Engineering;

    Sammanfattning : As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. LÄS MER

  3. 2. Effects of Prolonged Electricity Supply Disruptions on Critical Entities

    Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :André Hansson; [2023]
    Nyckelord :vital societal function; VSF; critical entity; CE; vital societal entity; VSE; critical infrastructure; CI; critical flow; prolonged outage; electricity supply disruption; preparedness; total defence; civil defence; civil preparedness; crisis preparedness; grey zone; critical entities resilience; CER; hybrid warfare; energy security; societal resilience; cascading effect; dependencies; interdependencies; long-term disruption; power outage; power disruption; consequences; outage; samhällsviktig verksamhet; kritisk infrastruktur; totalförsvar; beredskap; Technology and Engineering;

    Sammanfattning : This study investigates Swedish critical entities (CEs) ability to maintain function during up to three months of electricity supply disruptions. It also examines possible improvement measures, and how contextual cases (grey zone, heightened state of alert, war) influence CEs’ ability to maintain function during electricity supply disruptions.

  4. 3. Community Continuity Management : An Exploration of the Energy Production and Use of a Fictional Stockholm Neighbourhood in a Crisis

    Master-uppsats, KTH/Urbana och regionala studier

    Författare :Nils Brattgård; [2023]
    Nyckelord :Business Continuity Management; Community Continuity Management; Energy Community; Energy Resilience; Energy; Resilience; Preparedness; Adaptation; Wellness; Wellbeing; Blackout; Power Failure; High Impact Low Probability; Crisis; Disaster; Kontinuitetshantering; Community Continuity Management; Energigemenskap; Energiresiliens; Energi; Resiliens; Beredskap; Anpassning; Välmående; Välbefinnande; Strömavbrott; Elkris; High Impact Low Probability; Kris; Katastrof;

    Sammanfattning : In an increasingly interconnected, and electricity-reliant world, households are asked to build up their resilience to crises. Local, distributed electricity production within a microgrid with capability to operate disconnected from the larger grid has been shown to be an effective tool for increasing power system resilience in the past.

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

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Business Case Tools för distribuerade solcellsanläggningar : En Power BI-modell för investeringsmodellering och visualisering i Sverige

    Kandidat-uppsats, Uppsala universitet/Industriell teknik
