Abstract
A solar tower CSP power plant with a thermal storage system was simulated in the cities of Dagget (California/USA) and Petrolina (Pernambuco/Brazil) using solar data files in the Typical Metrological Year 2 format. The computational programs used for the solar power plant simulation were the EES, SAM and TRNSYS. The EES software was used to write the code of the power block subsystem that outputted its needed parameters, for 41.2% of thermal efficiency. The SAM software was used to determine the parameters of the solar field and the thermal storage subsystems, in their most profitable setups, for each city. Finally, the designed solar tower CSP power plant was simulated in the TRNSYS software, outputting the interrelationships between the three subsystems during a typical year. The energy output of the plant in the solstices and equinox were plotted. The simulated power plant in the city of Petrolina outputted less (11.2%) annual energy than Dagget power plant. In addition, even with a solar field with 55.4% more heliostats, the Petrolina solar power plant capacity factor was 8.5% lower. Through the study carried out, Dagget showed to be a more suitable location for the designed solar tower.
