  1. 1. Diving Deep: Seabird foraging tactics and local prey field

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Elin Andersson Sjöholm; [2024]
    Keywords : Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Abstract : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. READ MORE

  2. 2. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yujun Han; [2023]
    Keywords : Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

    Abstract : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. READ MORE

  3. 3. Data Centres as Prosumers: A Techno-Economic Analysis

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Jeremy Ericsson Sintong; [2023]
    Keywords : Data Centres; Prosumers; Techno-Economic Analysis; Waste Heat Recovery; District Heating; Heat Supply; Air-Cooled Data Centre;

    Abstract : Rapid growth of digitalization has urged Data Centres (DC) to be more energy efficient by recovering waste heat from server racks that would otherwise be wasted. This techno-economic study is focused on upgrading low temperature waste heat from typical Air-Cooled DC for District Heating Network (DHN) market in Stockholm region. READ MORE

  4. 4. Energy Poverty : Computing the silent problem of developed countries

    University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Author : Alfred Larsson; Märta Strømme; Herman Falkenmark; Freja Klucis; [2023]
    Keywords : Energy Poverty;

    Abstract : Energy poverty is a new term in the Swedish context, though it is becoming increasingly more relevant because of inflation and higher prices for electricity. Because research on the matter is scarce in developed countries such as Sweden and similar contexts in the EU, it creates uncertainty whether there is a ‘correct’ way of conducting energy poverty research.

  5. 5. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

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

    Author : Raúl Calvo García; Jose María Marín Arcos; [2023]
    Keywords : Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

    Abstract : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.
