A short- and long-term demand based analysis of a CO2 concentrated solar power system with backup heating

Economic and environmental assessment of a CO2 solar-powered plant with packed-bed thermal energy storage

“…Then, the control scheme decides for TES charging (light blue background), TES discharging (light red background), or straight auxiliary heating based on the outlet temperature for a TES time step of Δt TES = 60 s. Also, although the numerical routines developed can account for short-term perturbations like in Ref. [26], the hourly resolution of the TMY data diminishes their influence on the system's performance. Hence, for enabling less computationally expensive modeling, the overall system does not consider such perturbations in detail.…”

“…For the solar field, the modeling of Refs. [26,41] is employed. The solar heat gain in the solar collector field is calculated using the thermal performance reported for a parabolic trough field, whose efficiency depends on the average temperature of the absorber.…”

“…For more detailed information on the modeling employed for the solar collectors, one may refer to Refs. [26,41].…”

“…Like Ref. [26], which investigated the short-and long-term performance of a recompression CO 2 power cycle with a two-tank storage, other works also considered off-design modeling for evaluating the annual performance of a centralcollector plant with TES alternatives, e.g., Ref. [27].…”

Exergy Analysis and Off-Design Modeling of a Solar-Driven Supercritical CO2 Recompression Brayton Cycle

“…Since then, s-CO 2 has been studied as an interesting working/heat transfer fluid for different applications [6]. The potential of s-CO 2 RcBCs has sparked the interest of many, and they are under study for deployment in several applications, such as nuclear energy [7,8], solar energy systems [9,10], and marine propulsion [11].…”
