Abstract—To increase the flexibility of thermal power plants, a thermal high-performance storage system has been developed. The THERESA test facility has subsequently been designed and built for experimental investigations. The included high-performance storage system consists of a displacement storage and mixing preheater. A dynamic ATHLET model of a high-performance storage system is being developed. Our aim is a simulation-assisted design of thermal high-performance storage systems that would increase the flexibility of thermal power plants. Our focus is in particular on the improvement of the load change rate, the increase of balancing energy provision, the reduction of minimum load, the decrease of lifetime consumption, and the improvement of black start capability.
