  2. 2. Small-Scale Decentralized Energy Systems : optimization and performance analysis

    Author : Sara Ghaem Sigarchian; Viktoria Martin; Anders Malmquist; Erik Dahlquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

    Abstract : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. READ MORE

  3. 3. 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

  5. 5. Combined Energy Systems Applied to Productive Sectors: The Case of Dairy Farms in Central Bolivia

    Author : Johnny Villarroel-Schneider; Anders Malmquist; Andrew R. Martin; Monica Odlare; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bolivia; polygeneration; trigeneration; productive sector; dairy; biogas; electricity; refrigeration; multiservice; performance; techno-economic; Bolivia; poligeneración; trigeneración; sector productivo; lechería; biogás; electricidad; refrigeración; multiservicio; eficiencia; tecno-económico; Energiteknik; Energy Technology;

    Abstract : Most energy solutions in developing countries focus primarily on solving domestic energy demands of their growing populations without due consideration of sustainable development. On the other hand, in most of these countries, a segment of energy users that has not received enough attention from governments and institutions regarding appropriate energy solutions is the productive sector.
