An important block of a concentrated solar thermal plant is the solar field. In this block, the solar energy is concentrated as thermal energy in a fluid. An estimation of the available thermal power based on the available solar resource is a useful information in several applications. This estimation can be obtained using a solar field model based on first-principles. However, to build a model of this kind, can be complex and requires a human expert with in depth knowledge of the solar filed to be modeled. This work proposes an alternative, to use empirical models of the solar field. In this case, the model is obtained using a set of measurements from the solar field. Two kind of empirical models are proposed: parametric and data-driven models. In order to study the applicability of the proposed models, the optimal self-scheduling generation problem in a concentrated solar thermal plant is considered. Several scheduling strategies with different solar field models are compared in a simulation context. The simulations show that the strategies with empirical models of the solar field provides competitive results and then, can be considered as an alternative to the strategies based on first-principles models. The empirical models simplify the development of a generation scheduler.
