  1. 1. Dygnsreglering av småskalig vattenkraft i Jädraån

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Simon Ågren; [2023]
    Nyckelord :Vattenkraft; dygnsreglering; produktionsplanering; produktionsmodellering;

    Sammanfattning : The purpose of this project was to investigate the viability of daily production planning of the small-scale hydropower plants owned by Småkraft AB in Jädraån. In order to achieve this a number of characteristics of the river and the power plants first had to be estimated. LÄS MER

  3. 2. Flexibilitet i elsystemet : En undersökning om hur flexibilitet lokalt kan samverka med de nationella stödtjänstmarknaderna

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Isabella Agerhäll; [2022]
    Nyckelord :Stödtjänster; flexibilitet; eleffekt; kapacitet; elnät;

    Sammanfattning : The Swedish power system is facing a lot of change in the near future. A system which is built around nuclear- and hydropower now contains more and more intermittent power sources such as wind and solar. In addition, Sweden is entering a second electrification era, where the electricity use is predicted to increase substantially. LÄS MER

  4. 3. Modeling the Head Effect in Hydropower River Systems using MILP and BLP Approaches

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Lina Larsson; Mikaela Lindberg; [2022]
    Nyckelord :Hydropower optimization; Hydropower scheduling; The head effect; Bilinear programming; Mixed-integer linear programming;

    Sammanfattning : With a fast-growing electricity demand and a larger proportion of intermittent energy sources follows a greater need for flexible and balancing sources of electricity, such as hydropower. Planning of hydropower production is considered to be a difficult problem to solve due to several nonlinearities, combinatorial properties and the fact that it is a large scale system with spatial-temporal coupling.

  5. 4. To create multifunctional riverscapes : the example of Älvkarleby in the Nedre Dalälven River, Sweden

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Xuan Ye; [2022]
    Nyckelord :river space; municipal nature reserve; ecological restoration; landscape planning; fish migration passage; human recreation;

    Sammanfattning : The natural environment and ecological services of rivers and the needs and expansion of human activities using rivers causes conflicting interests. Human survival is inseparable from the dependence on the natural environment, but at the same time, the continuous demand for natural resources has also caused an irreversible impact. LÄS MER

  7. 5. Assessment of hydropower mitigation measures for fish habitat rehabilitation with a coupled eco-hydraulic model : A case study on the Skålan-Äldern stretch

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Francesca Polato; [2021]
    Nyckelord :hydropower; mitigation measures; ecological flow assessment; hydraulic modeling; physical habitat models; vattenkraft; begränsande åtgärder; ekologisk flödesbedömning; hydraulisk modellering; fysiska livsmodeller;

    Sammanfattning : In the past century, hydropower development in Sweden has been facilitated by the lack of appropriate environmental legislation. This exploitation has resulted in the current poor ecological status of most Swedish water bodies affected by hydropower, and in the need for new policies that reflect the 2000 European Water Framework Directive.
