  1. 1. 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

  3. 2. "Där borta, ungefär i skogsdungen, lite höger, cirka 300 meter" : Underlätta kommunikationen för UMS Skeldars piloter

    M1-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Pernilla Ljungqvist; Alma Wärnsäter; [2023]
    Nyckelord :;

    Sammanfattning : Unmanned aerial vehicles (UAV), have gained increasing importance for the military, public safety and various authorities. This paper is carried out together with UMS Skeldar, which works on developing UAVs, which are controlled from a ground station containing two people, a pilot and a sensor operator. LÄS MER

  4. 3. Energilager i kyrkan och dess systemnyttor : Batterier i kyrkan och hur de kan bidra till ett stabilare elnät

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Axel Eriksson; David Norman; [2023]
    Nyckelord :stödtjänster; batterisystem; energilager; peakshawing; spänningsreglering; flexibilitetsmarknader; kyrkan;

    Sammanfattning : Many of the over 3300 churches in Sweden are only used a couple of times a week and are kept cold in between sessions. The occasional heating results in a power spike which burdens both grid and wallet in form of an increased grid fee. With the help of a battery and peak shaving, the peak can be lessened. LÄS MER

  5. 4. Control barrier function-enabled human-in-the-loop control for multi-robot systems : Centralized and distributed approaches

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

    Författare :Victor Nan Fernandez-Ayala; [2022]
    Nyckelord :Multi-robot systems; Human-in-the-loop control; Control barrier functions; Safety constraints; ROS Implementation; Multirobotsystem; Human-in-the-loop-kontroll; Kontrollera barriärfunktionerna; Säkerhetsbegränsningar; ROS-implementering;

    Sammanfattning : Autonomous multi-robot systems have found many real-world applications in factory settings, rescue tasks and light shows. Albeit these successful applications, the multi-robot system is usually pre-programmed with limited flexibility for online adaptation. LÄS MER

  7. 5. Submillimeter 3D surface reconstruction of concrete floors

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Björn Hagström; Hampus Wallström; [2022]
    Nyckelord :Submillimeter; Structured light; Sinusoidal phase shift; Concrete; Surface reconstruction; Defocused binary pattern;

    Sammanfattning : During the creation of any concrete floor the concrete needs to be grinded down from it's very rough newly poured form to a more usable floor surface. Concrete floor grinding is very special in that the work area is often immensely large while the height difference on the surface is incredibly small, in-fact the the largest local difference of the surface from a peek to a valley during the grinding process is submillimeter and goes down to micrometer scale.
