With the same stored thermal energy to heat the bypassed feed water of 308.65 t/h, the power output can be increased to 394.2 MW from 360.07 MW (60% rated load) at the same sensible heat storage
Energy storage systems are not only a potential solution for connecting renewable energy to the grid but can also effectively increase the flexibility of power plants [10–12]. Carlson et al. [13] proposed the combination of thermal energy storage (TES) and nuclear power Rankine cycle to improve the flexibility of base load.
A shell-and-tube design with different thermal energy storage (TES) media was investigated as a promising TES system for a next generation concentrated solar power (CSP) plant. Sensible TES using graphite, latent TES using phase change materials (PCMs) and a hybrid of both were investigated.
TSPP use solar- and bioenergy and grid surplus as primary energy sources for dispatchable power generation. Dispatchable renewable electricity is the key for energy transition also in industry, heat and transport. A model scenario for Germany with TSPP shows how transition to 100% renewable electricity can be achieved until 2040.

In energy network operation, some scholars have researched energy storage capacity planning in island power systems, with total cost reduction as the optimization objective [11]. The capacity of energy storage facility under different scenarios is the key to improve the resilience of the islanded microgrid to uncertainty [12].
