  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

  3. 2. Cannibalization of Renewable Energy in Spain: Market Implications and Mitigation Strategies through CArbon Pricing and Gurarantess of Origin

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

    Författare :Fredrik Lannhard; [2023]
    Nyckelord :Cannibalization; Renewable energy; Marginal pricing; Day-ahead markets; Spain; Electricity market simulation; Carbon pricing; Guarantees of origin.; Kannibalisering; Förnybar energi; Marginalprissättning; Spotmarknader; Spanien; Elmarknadssimulering; Koldioxidprissättning; Ursprungsgarantier.;

    Sammanfattning : Renewable cannibalization refers to the phenomenon where the increasing penetration of zeromarginal cost renewable energy sources, such as solar and wind power, leads to a decline in their market value. By extension, this threatens to reduce investment incentives in wind and solar. LÄS MER

  4. 3. X-Ray Tomography on Intestine Samples

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Julia Rogalinski; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Enteric neuropathy describes a disease of the bowel caused by anomalies in the enteric nervous system. Patients suffering from this disease have symptoms including nausea, vomiting, diarrhea and pain. As enteric neuropathy is not well understood yet, its diagnosis is a non-trivial task. LÄS MER

  5. 4. Tidig detektering avgranbarkborreangrepp med hjälp avfjärranalys via Sentinel-2

    Kandidat-uppsats, Högskolan i Gävle/Datavetenskap

    Författare :Najm Eddin Eid; Petter Jakobsson; [2022]
    Nyckelord :Remote sensing; Sentinel-2; spruce bark beetle; spruce forest; vegetation analysis; vegetation index; band combinations; image analysis.; Fjärranalys; Sentinel-2; granbarkborre; granskog; vegetationsanalys; vegetationsindex; bandkombinationer; bildanalys.;

    Sammanfattning : Granbarkborre är en av Sveriges mest destruktiva skadeinsekter som angriper granskog. Insekten har medfört förödande konsekvenser för granskog, framför allt sedan2018 där stora arealer granskog nästan har eliminerats. Insekten trivs i varmt ochtorrt klimat. LÄS MER

  7. 5. Potential rooftop photovoltaic energy production calculation for Residential Buildings in Visby-----Case study about Gotlandshem

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Xiang Li; [2022]
    Nyckelord :Photovoltaics; Residential Buildings; Sustainable Energy Transition; Sustainable Development; Gotland; Gotlandshem; LCOE;

    Sammanfattning : Solar energy is one type of the most commonly used renewable energy sources. It can produce electricity and heat without creating any Greenhouse Gases (GHG). LÄS MER
