  1. 6. Stability Related Issues for High Wind Power Penetration : Exploring possibilities to enhance grid stability from synthetic inertia in a future scenario

    Magister-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Christian Ekstrand; Farsad Mansori; [2020]
    Nyckelord :PMSG; Power system stability; PSS E; Synthetic inertia.;

    Sammanfattning : The future global energy transition favour renewables such as wind power, which is predicted to be one of the predominant sources harvesting abundant amounts of energy onwards. Consequently, causing several conventional synchronous generators to be decommissioned in a near future to achieve an overall reduction in greenhouse gases related to electricity generation. LÄS MER

  3. 7. Optimal Day-Ahead Scheduling and Bidding Strategy of Risk-Averse Electric Vehicle Aggregator : A Case Study of the Nordic Energy and Frequency Containment Reserve Markets

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

    Författare :Jacob Dalton; [2018]
    Nyckelord :;

    Sammanfattning : The Nordic synchronous grid is facing a number of challenges. The ongoingphaseout of synchronous generation coupled with increased penetration ofintermittent renewable generation is leading to reduced system inertia. LÄS MER

    Sammanfattning : This report travels through multiple disciplines to seek innovative and sustainable energy solutions for wastewater treatment plants. The first subject is a report about increased global temperatures and an over-exploitation of natural resources that threatens ecosystems worldwide. LÄS MER

  5. 9. Ancillary Services from Wind Power : - A Market Assessment

    Master-uppsats, KTH/Energiteknik

    Författare :Antonia Rekman; Matilda Richter; [2017]
    Nyckelord :;

    Sammanfattning : Today’s electricity system faces a lot of challenges. The Swedish TSO, SvK, has expressed an increased worry about the system reliability and fears for the grid robustness. This worry stems from a continuously growing share of electricity produced from non-plannable production such as wind power. LÄS MER

  7. 10. Utvärdering av konsekvenserna för nätanslutning av vindkraftparker i Sverige vid införandet av nätkoden Requirements for Generators

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Erik Andersson; Fredrik Wengberg; [2015]
    Nyckelord :Requirements for generators; RfG; wind farm Grid Code Compliance; Nätkoder; Vindkraft; Elnätsanslutning;

    Sammanfattning : Grid codes are becoming more demanding on power generating units due to the factthat the complexity of the power grid is increasing. The penetration of wind powerhas grown over the last years and it is clear that wind farms need to be addressedwith the same type of grid codes as conventional generation units. LÄS MER
