  1. 1. Åtgärder mot förhöjda halter av per- och polyfluorerade alkylsubstanser (PFAS) i dagvatten : Styrande mål och riktvärden

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Felicia Hagberg; [2024]
    Nyckelord :PFAS; PFCA; PFSA; stormwater; guidelines; foam fractionation; activated carbon; anion exchangers; PFAS; PFCA; PFSA; dagvatten; riktvärden; åtgärder; skumfraktionering; aktivt kol; jonbytare;

    Sammanfattning : Stormwater is a significant transport medium for pollutants to recipients located near cities. Substances commonly found in stormwater include nutrients, metals, organic substances and particles. A group of pollutants detected in stormwater are per- och polyfluoroalkyl substances (PFAS).

  3. 2. Evaluation of OPAL-RT Simulator through Simulation of Microgrid with High Penetration of DER

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Anton Grönberg; [2024]
    Nyckelord :Real-Time simulation; Power System Simulation; OPAL; DER;

    Sammanfattning : This thesis was written in collaboration with the department of electrical engineering at Uppsala University. It evaluates and tests the potentials and limitations of using the OPAL-RT simulator as a tool for designing and developing control strategies used in microgrids with a high penetration of distributed energy resources.

  4. 3. Evaluating the accuracy of NEWA, ERA5 and NORA3 in predicting onshore wind conditions: a comparative study using ICOS meteorological mast data in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Svetlana Kuru; [2024]
    Nyckelord :NEWA; ERA5; NORA3; wind speed; wind distribution; correlation coefficient;

    Sammanfattning : The ECMWF Reanalysis v5 (ERA5), the New European Wind Atlas (NEWA), and the 3 km Norwegian Reanalysis (NORA3) are reference datasets that are available for industry and research. The resolution of 3km in both the NORA3 and NEWA datasets sets them apart, while ERA5, with its 31km resolution, continues to serve as a reliable data source that is widely used in the industry.

  5. 4. Local Voltage Control in Converter Based PV Generation

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

    Författare :Charlotta Sporre; [2024]
    Nyckelord :distributed generation; active network management; low voltage distribution network; delta control; voltage control; Technology and Engineering;

    Sammanfattning : As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. LÄS MER

  7. 5. Oscillations in a complex sunspot: From theory to data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Femke Kranenbarg; [2024]
    Nyckelord :;

    Sammanfattning : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.
