    Sammanfattning : Physical asset management in the electric power sector encompasses the scheduling of the maintenance and replacement of grid components, as well as decisions about investments in new components. Data plays a crucial role in these decisions. LÄS MER

  4. 8. Solar Variability Assessment and Grid Integration : Methodology Development and Case Studies

    Författare :David Lingfors; Joakim Widén; Uwe Zimmermann; Eva Wäckelgård; Tobias Boström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar variability; Photovoltaics; Grid integration; GIS; Distributed generation; Engineering Science; Teknisk fysik;

    Sammanfattning : During the 21st century there has been a tremendous increase in grid-connected photovoltaic (PV) capacity globally, due to falling prices and introduction of economic incentives. PV systems are in most cases small-scale, installed on residential dwellings, which means that the power production is widely distributed and close to the end-user of electricity. LÄS MER

  5. 9. Grid reinforcing wind generation

    Författare :Nayeem Ullah; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transient stability; variable speed wind turbine; long term voltage stability; short term voltage stability; frequency converter;

    Sammanfattning : In this thesis, effects of some grid assisting possibilities that wind turbines could be equipped with, are investigated. The background is that concerns regarding the stability of the already existing power system in the presence of large wind farms have been risen. LÄS MER

  7. 10. Grid connection of offshore renewable energy sources

    Författare :Christoffer Fjellstedt; Karin Thomas; Mats Leijon; Daniel Månsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grid connection; Electronic filters; Power transformers; Offshore collection grids; HVDC transmission; HVAC transmission; Marine current energy; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : In order to achieve net zero emissions from the electricity sector, the proportion of renewable energy sources connected to the electrical grid needs to be increased significantly in the coming years. Established renewable energy sources, such as wind power and solar power, will certainly be crucial in achieving this. LÄS MER
