  1. 16. 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.

  3. 17. Local voltage control in a low voltage grid with high photovoltaic penetration

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Joakim Bakklund; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

  5. 19. N-body simulations of exoplanets and their moons

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Lydia Schollmeier; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. LÄS MER

  7. 20. Variation Management Strategies for Future Construction Sites: A study to address role of an equipment rental business in the energy transition

    H-uppsats,

    Författare :Ellen Blanksvärd; Frida Svensson; [2023-09-21]
    Nyckelord :battery storage; variation management; flexibility services; peak shaving; load shifting; demand side management; rental business; electrification; construction equipment; construction sites;

    Sammanfattning : Construction sites are facing challenges with high power peaks due to electrificationof heavy equipment where potential consequences are increased power tariffs locallyand risk of limited power supply. Another development is an increased intermittentpower supply due to more wind- and solar power in the electricity system, whichcauses price fluctuations. LÄS MER
