Assessment of Direct Thermal Energy Storage Technologies for Concentrating Solar Power Plants

Dynamic simulation, design improvements and control issues in solar power plants might compete with special considerations on storing techniques along with optimal store technically and from economic point of view. In order to provide the stability in production of power in spite of inconsistency in the source of energy, i.e., sun, overall concerns in the details of solar power plant, competition and comparison of common storing technologies should be taken into account in designation of the plant and plantwide control based on the performance of the storage in charging and discharging periods for the delivery and produce the electricity steadily. This research activity is mainly focused on the simulation of solar power plant for direct thermal energy storage technologies (double-tank and single-tank storage technologies) with DYNSIMTM suite to simulate dynamics and control the entire of plant and FLUENTTM for computational fluid-dynamics studies of thermocline effects in single-tank storage. Assessment of effectiveness, controllability, and flexibility of different direct technologies are brought together with the development of ad hoc control strategies to manage optimally.
