  1. 1. Improvement of Wind Power Forecasting and Prediction of Production Losses Caused by Ice Formation on Wind Turbine Blades : - A Machine Learning Approach

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Emelie Sjökvist; [2023]
    Nyckelord :;

    Sammanfattning : In the ongoing climate crisis, transitioning to renewable energy sources is essential to manage the increasing energy demand. One such renewable energy source is the weather-dependent energy source, wind power. Many wind farms are located in Cold Climate (CC) regions, known for their vast potential for wind power production. LÄS MER

  3. 2. Optimering av ett batterilager i kombination med ett större solcellssystem : Fallstudie: Gävle Energi ABs huvudbyggnad

    Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Carolina Johansson; [2020]
    Nyckelord :Effekttoppsreducering; frekvensreglering; batterilager; nätansluten fastighet; solcellssystem;

    Sammanfattning : The increase of variable renewable source leads to an imbalance between the electricity supply and demand of the power grid, as the solar and wind energy production is weather dependent. By implementing battery energy storage system (BESS), the balance can be improved by storing energy when the supply is high and then use when the supply is low. LÄS MER

  4. 3. Hybridization with CSP in a Cuban sugar mill

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Iris Vesterberg; Sofia Westerlund; [2018]
    Nyckelord :Cuban sugar cane industry; bagasse; concentrating solar power; hybrid power plant; electricity generation;

    Sammanfattning : Kuba har i dagsläget ett högt beroende av importerad olja, för att tillgodose sin växande efterfrågan på elektricitet. Importen sker främst från Venezuela. Detta beroende gör Kuba känsligt för ändringar i oljepriser samt det politiska klimatet. Den nuvarande krisen i Venezuela har haft en betydande inverkan på Kubas elproduktion. LÄS MER

  5. 4. Building predictive models for dynamic line rating using data science techniques

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Nicolae Doban; [2016]
    Nyckelord :Dynamic Line Rating; Data Science; Exploratory Data Analysis; Predictive Modeling; Energy Efficiency; Renewable Energy Sources; Power system planning and operations; Reproducible;

    Sammanfattning : The traditional power systems are statically rated and sometimes renewable energy sources (RES) are curtailed in order not to exceed this static rating. The RES are curtailed because of their intermittent character and therefore, it is difficult to predict their output at specific time periods throughout the day. LÄS MER

  7. 5. Assessing the Market Attractiveness for a Renewable Energy Source

    M1-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Carl Fredrik Leifland; Christoffer Löfquist; [2014]
    Nyckelord :Finland; wind power; feed-in tariff; weather dependent renewable energy source; business case evaluation; 20-20-20 targets; Technology and Engineering;

    Sammanfattning : Background The EU’s 20-20-20 targets determine that Finland’s share of energy consumption from renewable energy sources is to be 38 % by 2020, a target that the government intends to reach by expansion of wind power. The government has a beneficial feed-in tariff in place as an incentive for rapid wind power expansion, which has made both domestic and international developers evaluate the business case in Finland.
