The collector and cavity receiver of the same plant (DAHAN) are modeled by Qiang et al. [18] and the dynamic characteristics have been investigated under different disturbances based on the ‘‘STAR-90’’ simulation platform. Besides, Ferriere et al. [19] and Yebra et al. [20] have developed their own receiver model that corresponds to the French Themis and Spanish CESA-I tower plants respectively. Their model is also based on the energy balance.
