  1. 1. Downstream migration and survival of Atlantic salmon (Salmo salar L.) kelts and fallbacks when passing a hydropower plant

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Frans Byström; [2020]
    Keywords : migration; kelt; iteroparous; anthropogenic obstacle; survival; turbine passage;

    Abstract : Repeat spawners of Atlantic salmon may be of great importance for population stability, the return spawners can significantly contribute to recruitment of juveniles. To have a significant proportion of repeat spawners in the population, it is necessary that salmons can successfully migrate back to the sea after spawning upriver. READ MORE

  2. 2. Techno-Economic Analysis of an Innovative Purely Solar Driven Combined Cycle System based on Packed Bed TES Technology

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tianqi Ruan; [2019]
    Keywords : Tower CSP Techno-economic analysis; Dynamic simulation; Tower CSP teknisk-ekonomisk analys; Dynamisk simulering;

    Abstract : With increasing awareness of environmental issues and worldwide requirements for sustainable development, renewable energy technologies with lower environmental impact, especially those having abundant resources like wind and solar energy, attract more attention. Concentrating Solar Power (CSP) is one of the most promising solar energy technologies. READ MORE

  3. 3. Power Plant Operation Optimization Economic dispatch of combined cycle power plants

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Stefano Rosso; [2019]
    Keywords : ;

    Abstract : As electricity production from renewable sources increases, higher flexibility is required by fossil fuel generation to cope with the inherent fluctuations of solar and wind power. This results in shorter operating cycles and steeper ramps for the turbines, and more uncertainty for the operators. READ MORE

  4. 4. Analysis of uncertainties in fatigue load assessment : a study on one Kaplan hydro turbine during start operation

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Annica Gustafsson; [2019]
    Keywords : Hydropower; Hydro turbine runner; Uncertainty analysis; Fatigue load; Fatigue damage; Propagation of uncertainty.; Vattenkraft; Löphjul; Osäkerhetsanalys; Utmattning; Delskada; Fortplantning av osäkeheter.;

    Abstract : In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. READ MORE

  5. 5. LCA of Microgrid System: a Case Study at ‘North-five Islands’ of Changshan Archipelago, China

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jiang Yuning; [2019]
    Keywords : Microgrid system; Life cycle Assessment LCA ; Climate change impact; Greenhouse gas emissions GHG ; China;

    Abstract : Microgrid can provide stable, clean, and sustainable electricity supply for remote places since it can operate on renewable energy sources and work isolated from the utility grid. This thesis evaluates the life cycle greenhouse gas (GHG) emissions of the microgrid system which is located at the ‘North-five Islands’ of Changshan archipelago in China. READ MORE
