  1. 16. Analysis of the efficiency and performance of half-cell solar modules

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Diego Hernandez; [2023]
    Nyckelord :Shading; half-cell module; efficiency; PV facility; photovoltaic; solar energy; Matlab; simulink;

    Sammanfattning : Solar photovoltaic energy has gained great importance in the last couple of years, as its costs getlower and the total installed capacity increases. As a result of this, new technologies are arisingwithin the field, with the objective of increasing performance and reducing costs. LÄS MER

  3. 17. Evaluation of key performance indices for frequency quality : A method for evaluating frequency stability in the Nordic power system

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

    Författare :Sophia Larbi Engelbrektsson; [2023]
    Nyckelord :Ancillary Services; Kinetic Energy; Frequency Dependent Load; Frequency Stability; Frequency Quality; KPI; Nordic Power System; Frekvensberoende Last; Frekvenskvalité; Frekvensstabilitet; Kinetisk Energi; Nordiska Elsystemet; Nyckeltal; Stödtjänster;

    Sammanfattning : The Nordic power system is in a changing phase, with more power electronic interfaced connections, and HVDC connections to other synchronous areas, which impacts the frequency quality. This is a challenge for the transmission system operator of Sweden, Svenska Kraftnät, who, with the other Nordic transmission system operators, is responsible for the physical balancing of the Nordic power system.

  4. 18. Grey-box Modeling of Hydropower Plants for Improved Frequency Regulation : Evaluation of Double-Regulated Hydropower Turbines for Fulfillment of the New FCR-requirements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Karolina Engström; Rebecca Waldenfjord; [2023]
    Nyckelord :Double-regulated hydroturbines; Grey-box modeling; FCR-requriements; Frequency contaminent reserve; Hydropower modeling; Dynamic stability; Dynamic performance;

    Sammanfattning : Over the last decades, the frequency on the Nordic electrical power grid has deteriorated. Therefore, new stricter requirements are developed for the hydropower delivering regulating active power on the Frequency Containment Reserve market (FCR). LÄS MER

  5. 19. Modelling and Simulation of Hydrogen Electrolyzers for Power System Applications

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

    Författare :Javier Vinuelas Ferrando; [2023]
    Nyckelord :;

    Sammanfattning : The rapid increase in the share of intermittent renewables in the energy mix is exacerbating the complexity of the grid stability. To facilitate the inclusion of these green technologies and achieve the climate targets set by the EU, the generation and storage of hydrogen through electrolysis may be crucial. LÄS MER
