  2. 41. Combined solar and pellet heating systems : Study of energy use and CO-emissions

    Author : Frank Fiedler; Rebei bel Fdhila; Wolfgang Streicher; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heating; pellet heating; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

    Abstract : In this study 4 solar and pellet heating systems have been studied with the help of annual dynamic simulations. Two of the systems comprised a pellet stove and two systems were solar combisystems; one with a store integrated pellet burner, the other with a separate pellet boiler. READ MORE

  4. 42. A novel solar-driven system for two-step conversion of CO2 with ceria-based catalysts

    Author : Bo Wei; Reza Fakhrai; Torsten Fransson; Nader Jand; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 conversion; solar; ceria; thermogravimetric test; exergy analysis; simulink; fluidized bed; gas-solid flow; simulation; Energiteknik; Energy Technology;

    Abstract : Global warming is an unequivocal fact proved by the persistent rise of the average temperature of the earth. IPCC reported that scientists were more than 90 % certain that most of the global warming was caused by increasing concentrations of greenhouse gases (GHG) produced by human activities. READ MORE

  5. 43. Grid-forming wind power plants

    Author : Anant Narula; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power plants WPPs ; grid-forming GFM ; inertia; Ancillary services; frequency support; coordination; current limitation; energy storage systems ESS ; transient stability;

    Abstract : With growing concerns over climate change, the power system is witnessing an unprecedented growth in electricity generation from intermittent renewable energy sources (RES) such as wind and solar, which are commonly interfaced to the grid by power-electronic converters. However, increasing the penetration level of converter-interfaced generation units reduces the number of synchronous generators (SGs) in the grid that provide system services to support voltage and frequency, either inherently or through mandatory requirements and market products.

  6. 44. Solar Variability Assessment in the Built Environment : Model Development and Application to Grid Integration

    Author : David Lingfors; Joakim Widén; Jan Kleissl; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Variability; Photovoltaics; Grid Integration; Distributed Generation; LiDAR; GIS; Engineering Science; Teknisk fysik;

    Abstract : During the 21st century there has been a rapid increase in grid-connected photovoltaic (PV) capacity globally, due to falling system component prices and introduction of various economic incentives. To a large extent, PV systems are installed on buildings, which means they are widely distributed and located close to the power consumer, in contrast to conventional power plants. READ MORE

  7. 45. Autonomous Power Systems based on Renewables - On generation reliability and system control

    Author : Jimmy Ehnberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Today one billion people are living in non-electrified areas. A majority of the people are living in rural areas in developing countries where there are no possibilities, neither economical nor technical, for grid extension. Instead energy sources like wood and fossil fuels are used. READ MORE
