Dynamic Simulation of a 1MWe Concentrated Solar Power Tower Plant System with Dymola

Abstract This paper presents a first vertion of a dynamic model of the 1 MWe Central Receiver System demo plant at Badaling in Beijing with the purpose of improving the performance and reliability of the CSP technology deployed at this plant using dynamic modelling by Dymola® software in the frame of cooperation between EDF R&D and IEECAS (Institute of Electrical Engineering of the Chinese Academy of Sciences). This dynamic model is capable of simulating the dynamic behavior of the entire CSP plant, covering the heliostat field, the superheated steam cavity receiver, the thermal storage system and the power block. In order to validate the model, the demo plant operation data is used. The recorded evolution of the different process parameters during the operation is compared to the results predicted by the dynamic model. According to the results obtained from the operation, the simulation predicts fairly well the main process parameters. The predicted trend of the dynamic behavior of the system is also satisfactory. The results show that the model could be used to support the operation of the entire solar thermal power tower system and help improve the performance of the CSP technology deployed at Badaling.
