  2. 36. Solar Variability Assessment and Grid Integration : Methodology Development and Case Studies

    Author : David Lingfors; Joakim Widén; Uwe Zimmermann; Eva Wäckelgård; Tobias Boström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar variability; Photovoltaics; Grid integration; GIS; Distributed generation; Engineering Science; Teknisk fysik;

    Abstract : During the 21st century there has been a tremendous increase in grid-connected photovoltaic (PV) capacity globally, due to falling prices and introduction of economic incentives. PV systems are in most cases small-scale, installed on residential dwellings, which means that the power production is widely distributed and close to the end-user of electricity. READ MORE

  4. 37. Reducing Carbon Emissions From Natural Gas-fired Power Plants – Biomass, Concentrated Solar and Carbon Capture

    Author : Erik Pihl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon capture and storage; bioenergy; biofuels; optimisation; modeling; solar thermal power; resource limitations; thermo-economic assessment;

    Abstract : In this thesis, possibilities to reduce emissions from combined cycle gas turbine (CCGT) plants are evaluated. The evaluation is done from two perspectives: techno-economic analysis, and analysis of the resource and integration potentials. READ MORE

  5. 38. Solar Irradiance Assessment in Agrivoltaic Systems : Understanding Photosynthetically Active Radiation Separation Models and Dynamic Crop Albedo Effect in Agrivoltaic Systems Modelling

    Author : Silvia Ma Lu; Pietro Elia Campana; Bengt Stridh; Anders Avelin; Marcos Lana; Giulia Vico; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agrivoltaics; Albedo; Photosynthetically Active Radiation; Decomposition Model; Solar Energy; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Agrivoltaics, also referred as agrivoltaic systems, present an appealing solution, owing to its dual land use and integrated food-energy system, for the shift to renewable energy. However, it raises concerns about the complex synergies and trade-offs between crop growth and solar photovoltaic panels. READ MORE

  6. 39. Sputtering-based processes for thin film chalcogenide solar cells on steel substrates

    Author : Patrice Bras; Charlotte Platzer-Björkman; Eric Jaremalm; Jan Sterner; Veronica Bernudez; Uppsala universitet; []
    Keywords : CIGS; CZTS; solar cell; photovoltaics; thin film; sputtering; annealing; gallium grading; blister; uniformity; stainless steel; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : Thin film chalcogenide solar cells are promising photovoltaic technologies. Cu(In,Ga)Se2 (CIGS)-based devices are already produced at industrial scale and record laboratory efficiency surpasses 22 %. Cu2ZnSn(S,Se)4 (CZTS) is an alternative material that is based on earth-abundant elements. READ MORE

  7. 40. Development of a Novel Gas Turbine Simulator for Hybrid Solar-Brayton Systems

    Author : Tianyao Pan; Björn Laumert; Wujun Wang; Konstantinos Kyprianidis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine simulator; concentrating solar power; hybrid solar-Brayton system; pressure controller; choked nozzle; Programmable logic controller; proportional solenoid valve.; Gasturbinsimulator; koncentrerad solenergi; hybrid solenergi-Brayton-system; tryckregulator; strypt munstycke; programmerbar logikkontroller; proportionell magnetventil.; Energiteknik; Energy Technology;

    Abstract : Hybrid solar-Brayton systems utilize both solar thermal energy and supplementary renewable fuels to provide controllable and dispatchable power output, which renders them a promising way to meet the growing energy demand and reduce the carbon footprints. However, existing testing facilities for key components in such hybrid systems often fail to accomplish the testing requirements, hence impeding the improvement of the renewable energy share and the overall efficiency.
