 Design and experimental validation of a computational effective dynamic thermal energy storage tank modelJavier Bonilla, Margarita M. Rodríguez-García, Lidia Roca, Alberto de la Calle and Loreto Valenzuela Energy, 2018, vol. 152, issue C, 840-857 Abstract: Concentrating solar thermal power plants rely in thermal energy storage systems in order to provide a stable power supply. However, they might not been able to meet power plant demands, mainly because of their storage sizes which are restricted due to economic reasons. One way of mitigating this effect is to control in an optimal way the charging and discharging processes. For the design and validation of advanced control strategies, an accurate dynamic model is essential. For this reason, a dynamic thermal energy tank model intended to be used in concentrating solar thermal power plant models is presented in this paper. The developed tank model is validated in charging and discharging processes and also at rest state in order to validate thermal losses dynamics. Simulation results are compared against experimental data from the CIEMAT-PSA molten salt testing facility.
