  2. 16. Energy Management in Smart Cities

    Author : Christian Francisco Calvillo Munoz; Lennart Söder; Alvaro Sanchez; José Villar; Rafael Cossent; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system model; Smart city; Distributed energy resources; Distributed generation; EV; Metro; Energy markets; Planning and operation model; Energy Technology; Energiteknik;

    Abstract : Models and simulators have been widely used in urban contexts for many decades. The drawback of most current models is that they are normally designed for specific objectives, so the elements considered are limited and they do not take into account the potential synergies between related systems.

  4. 17. Apply heat pump systems in commercial household products to reduce environmental impact : How to halve the electricity consumption for a household dishwasher

    Author : Peder Bengtsson; Jonas Berghel; Per Lundqvist; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; household appliance; electricity consumption; heat pump; environmental impact; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : In the household appliance industry, heat pump systems have been used for a long time in refrigerators and freezers to cool food, and the industry has driven the development of small, high-quality, low-price heat pump components. In the last few decades, heat pump systems have been introduced in other household appliances, with the express purpose of reducing electricity consumption. READ MORE

  5. 18. Assessment of energy storage systems for power system applications based on equivalent circuit modeling

    Author : Cong-Toan Pham; Daniel Månsson; Alfred Rufer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage system; Assessment; Equivalent circuit model; Suitability; ; Electrical Engineering; Elektro- och systemteknik; Energy Technology; Energiteknik;

    Abstract : Climate change triggered the rethinking of our current energy system. A restructuring is necessary and in progress with the goal to improve our energy supplychain in efficiency and sustainability. This has led to the increased use of renewable energy sources such as solar and wind power. READ MORE

  6. 19. Analysis and control of a hybrid vehicle powered by free-piston energy converter

    Author : Jörgen Hansson; Mats Leksell; Chandur Sadarangani; Anders Malmquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-piston energy converter; FPEC; series hybrid electric vehicle; SHEV; power management; energy management; powertrain evaluation; equivalent consumption minimisation; ECMS; linear engine; Electrical engineering; Elektroteknik;

    Abstract : The introduction of hybrid powertrains has made it possible to utilise unconventional engines as primary power units in vehicles. The free-piston energy converter (FPEC) is such an engine. It is a combination of a free-piston combustion engine and a linear electrical machine. READ MORE

  7. 20. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

    Author : Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

    Abstract : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. READ MORE
