  1. 1. 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

  3. 2. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements

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

    Författare :Viktor Olsson; [2023]
    Nyckelord :Local Geomagnetic Variations; Fluxgate Magnetometer; Space Weather; Solar Wind; Magnetic Measurements; Variometer; Solar Activity.; Lokala geomagnetiska variationer; Fluxgate-Magnetometer; Rymdväder; Solvinden; Magnetiska Mätningar; Variometer; Solaktivitet.;

    Sammanfattning : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. LÄS MER

  4. 3. Evaluating the Efficient Grid Utilisation Incentive : Through the design of the load flow indicator

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Industriell ekonomi och organisation

    Författare :Chris-Antony Ndayisaba; Isabelle Sammils; [2023]
    Nyckelord :Incentive regulation; DSO revenue cap; Load flow incentive; Efficient grid utilization; Even load; Demand side management; Weighted load factor; Utilization factor; Elnäts reglering; DSO intäktsram; jämnbelastning incitament; Effektivt nätutnyttjande; Laststyrning; viktad medellastfaktor; utnyttjningsgrad;

    Sammanfattning : The Swedish energy markets inspectorate (Ei) regulates the Swedish DSOs revenue cap, to ensure reasonable prices, efficiency, and quality of supply towards the end users. In combination with directives from the European Union and Sweden's environmental goal, Ei implemented efficient grid utilization to the DSOs revenue cap in 2016. LÄS MER

  5. 4. Krav för inmatning av el till nätet från batterier : Undersökning av villabatterier och elbilar via V2G

    M1-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Magnus Kallin; [2023]
    Nyckelord :requirements; energy storage; battery storage; islanding; V2X; V2L; V2H; V2G; electric vehicles; EV; krav; inmatning; energilager; batterilager; ödrift; V2X; V2L; V2H; V2G; elbilar; EV;

    Sammanfattning : Dagens samhälle har stort beroende av central elförsörjning för att ha kapacitet att fungera. Beroendet av centrala produktionsenheter kopplade till stamnätet kan i sin tur göra det svenska elnätet mer sårbart och ostabilt. LÄS MER

  7. 5. Simulating distributed PV electricity generation on a municipal level : Validating a model for simulating PV electricity generation and implementing it for estimating the aggregated PV generation in Knivsta Municipality

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Lisa Molin; Sara Ericson; [2023]
    Nyckelord :photovoltaic generation model; model validation; artificial intelligence; machine learning; convolutional neural network; LIDAR;

    Sammanfattning :   The deployment of distributed photovoltaic (PV) is accelerating worldwide. Understanding when and where PV systems will generate electricity is valuable as it affects the power balance in the grids. One way of obtaining this information is simulating the PV power production of systems detected in Remotely Sensed Data (RSD). LÄS MER
