  1. 1. Estimating Photovoltaic capacity using customs data : Model development of the tool NJORD and photovoltaics' characterization and impact on the African continent

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

    Författare :Albin Åbrink; [2023]
    Nyckelord :Photovoltaic; Trade analysis; Development Goals; Africa;

    Sammanfattning : Photovoltaics (PV) is one of the fastest growing power sources in the world in the last twenty years, being the most installed power source in almost half of the world's countries in 2020. Despite this, precise tracking of installations of PV does not exist in most of the world's markets due to PVs unique scalability and modularity. LÄS MER

  3. 2. Analys av påverkan från ökad mikroproduktion och installation av laddare för elfordon i lågspänningsnät

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :John Andersson; [2023]
    Nyckelord :rechargable card; charging stations;

    Sammanfattning : In Sweden, the number of rechargeable cars increases for every year. It is common to charge at home, for example because there is no need to wait for the vehicle to be fully charged.Charging at home takes place with low effects for longer time periods. The installation of micro production with photovoltaic systems is also increasing. LÄS MER

  4. 3. Mathematical Model for Inverter Power Output in PV Parks

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Shashidhar Suragimath; [2023]
    Nyckelord :Mathematical Modelling; PV System; Energy Systems; Solar Inverter; Forecasting;

    Sammanfattning : Solar photovoltaic (PV) parks have proliferated all over the world as a result of the growing demand for electricity, and especially electricity from renewables. As these parks become larger and complex, it becomes increasingly important to develop accurate and efficient mathematical models that can be used to predict their performance and optimize their design.

  5. 4. EV charging approaches in remote regions – Analysis of capacity, cost and logistics

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Farhaan Ahamed; Juan Ordonez Marin; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With countries across the world finding pathways to counter CO2 emissions, sustainable mobility has become a critical topic for leaders, policymakers, and industries. The development of Battery Electric Vehicles (BEV’s) is seen as an important and effective way through which reliance on fossil fuels and thereby related CO2 emissions can be reduced. 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
