D7.4 Final report on system model

This document is the deliverable D7.4 of the project POLYPHEM. It is planned in the framework of the Work Package 7 (System Modelling and Performance Assessment). In this WP, a finalized dynamic simulation model of the overall plant is developed in several steps. This deliverable contains the information for Task 7.4. Also in this task, a technoeconomic optimization of the plant has been developed based on the objective costs of the project. For this purpose, Fraunhofer ISE has developed the OPTIPHEM tool chain, which is responsible for designing the plant, evaluating the optical performance of the heliostat field, simulating the annual performance of the complete system model and performing the techno-economic optimization
