  2. 1. 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.
