  1. 16. Short-term planning and operational profitability of multi-ESS hybrid wind farms

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Javier Ortega Paredes; [2022]
    Keywords : Energy storage systems; day-ahead market; wind power; stochastic short-term planning problem; hybrid wind farm; Energilagringssystem; day-ahead-marknad; vindkraft; stokastiskt kortsiktigt planeringsproblem; hybridvindkraftverk.;

    Abstract : The unpredictability and variability of wind power generation can pose an economical risk to the wind power producer when participating in the day-ahead market and delivering the committed generation. These risks come from the creation of imbalances due to a mismatch between the sold and real generation fed to the grid. READ MORE

  3. 17. Alternative Energy Storage Solutions and Future Scenarios of the Austerland Energy System

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

    Author : Jennie Lindblom; [2022]
    Keywords : Gotland; Östergarnslandet; Polygeneration system; Homer Pro; Solar PV; Wind power; Energy storage; Battery; Hydrogen; Flywheel; Redox Flow battery; Pumped Hydro; Sustainable development.; Gotland; Östergarnslandet; Poly-genererings system; Homer Pro; Solceller; Vindkraft; Energilagring; Batterier; Vätgas; Svänghjul; Redox Flödesbatteri; Pumpkraftverket; Hållbar utveckling.;

    Abstract : The project Austerland Energi at the eastern tip of the island of Gotland called Östergarnslandet was started as a response to the larger project Omställning Gotland funded by the Swedish government as an effort for a pilot project to convert to renewable energy to reach zero CO2-emissions for the country in 2045. The current plan for the Austerland energy system is a solar PV and wind production base with energy storage in the form of batteries and hydrogen which also can be used as vehicle fuel. READ MORE

  4. 18. Storskalig solkraft i Arktis - vilka förutsättningar finns på 69°N?

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Anton Asplund; [2022]
    Keywords : Solar power Arctic Bifacial LCOE PV NPV LCA GWP High latitude area NO4; Technology and Engineering;

    Abstract : Norge behöver utöka sin elproduktion för att möta ett framtida ökat elbehov. Vattenkraften i Norge uppskattas endast ha 23 TWh kapacitet kvar att bygga ut och vindkraft har mött starkt motstånd på senare tid. Solkraft finns fortfarande bara på liten skala i landet men uppskattas öka kraftigt i närtid. READ MORE

  5. 19. ADAPTED FISH FRIENDLY OPERATION OF SMALL-SCALE HYDROPOWER PLANTS : AN ECONOMIC ANALYSIS

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ana Gil Merino; [2022]
    Keywords : ;

    Abstract : The hydropower sector generates almost half of the electricity produced in Sweden annually. Although hydropower is a renewable energy that produces no emissions, there is an impact on the local scale of Swedish aquatic ecosystem causing the decline of some fish species due to its impact on rivers connectivity.

  6. 20. Methane and Carbon Dioxide Emissions From Three Smallscale Hydropower Stations in South of Sweden

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Edevardt Johan Danielsen; Alexandra Jonsson Valderrama; [2022]
    Keywords : Hydropower; Reservoir; Freshwater; automated Flux chambers; Emissions; Ebullition; Diffusion; Greenhouse gases; GHGs; Methane; CH4; Carbon dioxide; CO2; Dissolved oxygen; DO; Variability; Spatial; Temporal; Dissolved inorganic carbon.; Vattenkraft; Reservoar; Sötvatten; automatiserade Fluxkammare; Utsläpp; Ebullition; Diffusion; Växthusgaser; GHHs; Metan; CH4; Koldioxid; CO2; Löst syre; DO; Variabilitet; Rumslig; Temporal; Löst oorganiskt kol.;

    Abstract : Over the past decades, evidence show that the anthropogenetic greenhouse gases (GHG) emissions of carbon dioxide (CO₂) and methane (CH₄) are the main drivers behind global warming and are becoming stronger. Globally, hydropower is among the main sources of renewable energy and the popular notion that hydropower electricity is carbon neutral has been under debate as evidence from measurements in different regions of the globe show significant and highly variable carbon emissions from hydropower reservoirs.
