  1. 1. 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

  3. 2. Hosting Capacity Methods Considering Complementarity between Solar and Wind Power : A Case Study on a Swedish Regional Grid

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Emma Andersson; Maja Abrahamsson Bolstad; [2023]
    Nyckelord :hosting capacity; hosting capacity methods; renewable power generation; power grid; power system analysis; complementarity; solar power; wind power; deterministic method; time series method;

    Sammanfattning : The demand for electrical power is growing due to factors such as population growth, urbanisation, and the transition from fossil fuels to renewable energy sources. To be able to keep up with the changes in electricity demand, the Swedish power grid must connect more renewable power generation, but also  increase its transmission capacity. LÄS MER

  4. 3. Optimization of loads and power production for wind turbines in Swedish conditions

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Manikanta Viswanadha Prabhu Kankatala; [2023]
    Nyckelord :;

    Sammanfattning : The project aims at quantifying differences in power production and fatigue loads for wind turbines placed in the Baltic sea and in forested, topographically-complex areas compared to turbines placed offshore and in flat terrain. Based on these results, suggestions will be provided on how to optimally site and operate turbines in these conditions. LÄS MER

  5. 4. Analysis to reduce ice-related production losses for wind turbines

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jhason Paran De La Cruz; [2023]
    Nyckelord :Wind power; cold climate; wind turbine icing; ice losses; ice protection systems; blade heating; de-icing; analytical dashboard; data visualization.; Vindkraft; kalla klimat; nedisning av vindkraftverk; isförluster; isskyddssystem; uppvärmning av blad; avisning; analysverktyg; datavisualisering.;

    Sammanfattning : In the rapidly growing wind energy market, regions with cold climates are currently in the spotlight owing to their abundance of wind resources. However, the operation of wind turbines in cold climate conditions is challenged by serious icing problems. LÄS MER

  7. 5. Relay settings for frequency derivative protection against islanding : Optimizing RoCoF-Hysteresis and Delay for the Swedish power grid: An investigation of relevant values

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Ahmad Safari; [2023]
    Nyckelord :Islanding; unintentional islanding; distributed energy resources; main grid; RoCoF; hysteresis; delay; Ödrift; oavsiktlig ödrift; distribuerade energiresurser; stamnät; RoCoF; hysteres; fördröjning;

    Sammanfattning : This report addresses the parameter settings for a protective relay designed to safeguard a 15 kW wind turbine located in Rimbo, Norrtälje municipality, against unintentional islanding. This type of situation arises when distributed energy resources continue to supply local loads, even if the main grid has been unintentionally disconnected. LÄS MER
