  1. 1. Sustainable Production Patterns for Hydropower Units

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Hannington Kayanja; [2023]
    Keywords : Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

    Abstract : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. READ MORE

  3. 2. Harmonisk strömsimulering i inverterbaserade värmepumpar

    University essay from Umeå universitet/Institutionen för fysik

    Author : Alexander Magnusson; [2023]
    Keywords : Current harmonics; inverter-driven compressor; black box simulation;

    Abstract : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sophia Larbi Engelbrektsson; [2023]
    Keywords : 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;

    Abstract : 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.

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

    University essay from Uppsala universitet/Elektricitetslära

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

    Abstract : 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). READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Javier Vinuelas Ferrando; [2023]
    Keywords : ;

    Abstract : 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. READ MORE
