Abstract

This work presents a thermodynamic model for a hybrid multistage Brayton thermosolar plant, with the aim of evaluating the efficiency and the power generation in different plant configurations. Improvements with respect a hybrid single stage Brayton thermosolar plant are proposed. This type of plants have two main energy sources for its operation, one from solar radiation, and the other one from the fuel combustion in a combustion chamber, making the values of the fuel consumption and the greenhouse emissions lower than other types of electric power generation plants. Moreover, this technology allows a stable power output (independent of solar irradiation fluctuations) without thermal storage systems.
