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

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

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

    Abstract : 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.

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

    University essay from SLU/Dept. of Urban and Rural Development

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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.

Sharing the industrial plot of the reworked silos are 13 buildings with 2000 households between them. READ MORE

  6. 5. A Swedish Nuclear Future : Using explorative scenarios to assess energy security in low-carbon electricity systems

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Viktor Andersson; [2020]
    Keywords : Sustainable Development; Energy Security; Scenario Analysis; Low-Carbon Electricity; Nuclear Energy; Energy System Planning;

    Abstract : Positioned within the concepts of sustainable development and energy security, this study evaluates the prospects for Swedish electricity production to assist in reaching both national and international climate targets. The main purpose is to assess the capability of nuclear energy to form part of a national climate change mitigation approach, as well as a viable energy source for Sweden to rely on in the future.
