  1. 1. 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

  3. 2. Changing Patterns over the FOMC Cycle

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Edvin Holst; Theodor Von Der Esch; [2023]
    Nyckelord :FOMC; Federal Reserve Board of Governors; Pre-FOMC announcement drift; Macro-announcements;

    Sammanfattning : We document that in the period 2017 to 2022, the US stock market did not feature the same pattern of higher excess stock returns in even weeks following Federal Open Market Committee (FOMC) announcements as in the period 1994 to 2016. We show that timing of Board of Governors meetings and direction of Fed funds target rate movements affect US market returns in both periods, and connect changes in these factors to the distortion of the even-week return pattern.

  4. 3. From Global to Regional - how Political Communicators made sense of Covid-19 Crisis. Evidences from 2020 Italian Regional Elections

    Master-uppsats, Lunds universitet/Institutionen för strategisk kommunikation

    Författare :Francesco Maria Parente; [2021]
    Nyckelord :Social Sciences;

    Sammanfattning : Described as a “paradigm shift” event (Michelson, 2020), the Covid-19 pandemic is challenging all humans activities worldwide. Such disruptive event can be labelled as a crisis, which is described as an episode of uncertainty threatening high priority goals (Sellnow & Seeger, 2013). LÄS MER

  5. 4. Constructing a Security Threat? : Identifying Securitization in US State Level Politics Framing of the BLM Protests

    Kandidat-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Rebecka Bjuremalm; [2021]
    Nyckelord :securitization; Copenhagen School; framing analysis; protest movements; Black Lives Matter; securitized citizens; contentious politics;

    Sammanfattning : This thesis investigates US state level politics framing of the BLM protests during 2020, by inductively identifying frames and then proceeding to study if and on what grounds securitization occurs in these. Press statements, interviews and documents from eight Mayors and Governors in six of the states where the protests have been the most prominent are analyzed. LÄS MER

  7. 5. Estimation of Inertia in Power Systems Using Electromechanical Modes

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Vidar Johnsson; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The transition to more renewable energy such as wind, leads to a decreased inertia in the power system. As a consequence of this, disturbances lead to larger frequency deviations and the frequency stability of the system is worsened. Therefore, there is a surging interest to estimate the inertia in the power system. LÄS MER
