Performance model for parabolic trough solar thermal power plants with thermal storage: Comparison to operating plant data

This paper describes a simulation model that reproduces the performance of parabolic trough solar thermal power plants with a thermal storage system. The aim of this model is to facilitate the prediction of the electricity output of these plants during the various stages of their planning, design, construction and operation. Model results for a 50 MWe power plant are presented and compared to real data from an equivalent power plant currently operated by the ACS Industrial Group in Spain.

► We describe a performance model for parabolic trough solar thermal power plants with thermal storage.
► We give full details of the simulation algorithm, relevant calculations and physical models used.
► We show excellent agreement between our results and actual data from an operating plant in Spain.
► Our model is the first of its kind to be validated against operating plant data.
► Our results offer unprecedented insight into the actual performance and operation of these plants.
