  1. 21. Prediction of the Impact of Increased Photovoltaics Power on the Swedish Daily Electricity Spot Price Pattern

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Saga Fahlén; [2022]
    Nyckelord :Regime Switching; Photovoltaics; Electricity Spot Price; Cannibalization Effect; Merit Order Effect;

    Sammanfattning : As the demand for electricity increases throughout the globe while we want to reduce the use of fossil fuels, the need for renewable energy sources is bigger than ever. In countries where solar power makes up a large part of the total energy production, the overall electricity spot price level has become lower. LÄS MER

  3. 22. 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

  4. 23. PV self-consumption: Regression models and data visualization

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

    Författare :Martos Tóth; [2022]
    Nyckelord :Self-Consumption; photovoltaics; battery; machine learning; solar energy; random forest; k-nearest neighbor; multi-layer perceptron; lasso regression; ridge regression; linear regression; Egenanvändning; photovoltaics; batteri; maskininlärning; solenergi; random forest; k-nearest neighbors; multi-layer perceptron; lasso regression; ridge regression; linjär regression;

    Sammanfattning : In Sweden the installed capacity of the residential PV systems is increasing every year. The lack of feed-in-tariff-scheme makes the techno-economic optimization of the PV systems mainly based on the self-consumption. The calculation of this parameter involves hourly building loads and hourly PV generation. LÄS MER

  5. 24. Solar cooling systems : A comparative analysis for solar thermal and solar PV cooling systems for Industries using a techno-economic approach

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Christoffer Larsson; [2022]
    Nyckelord :Photovoltaic cooling; solar thermal cooling; global LCOC;

    Sammanfattning : With the need to reduce CO2 emissions in the energy sector, ensure electric grid stability and reduce future cost uncertainties for process cooling, solar cooling can be an interesting solution. This report describes the comparison of solar cooling with either a photovoltaics system or a solar thermal system using a thermally driven chiller. LÄS MER

  7. 25. Evaluation of solar powered systems in small scale UAV designs

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

    Författare :Lukas Girlevicius; [2022]
    Nyckelord :;

    Sammanfattning : Unmanned Aerial Vehicles (UAV) also know as drones are becoming increasingly present in modern societies. Despite their versatility and success in many areas, small scale UAVs which are nearly always battery powered and therefore have limited flight endurance. LÄS MER
