Randomized trial investigates molten-salt storage's impact on energy flexibility in gas turbine plants, indicating improved performance.
Key Points
The aim is to evaluate the integration of molten-salt thermal energy storage into a gas turbine combined cycle power plant to enhance flexibility and efficiency.
Developed a thermodynamic model of the hybrid system using EBSILON Professional.
Assessed charging, discharging, and load-following operations with a focus on energy performance and cost.
Conducted a preliminary CAPEX assessment of the installed TES subsystem.
Achieved a round-trip efficiency of about 83.96%, with charging and discharging powers of 85.745 MWth and 86.241 MWth respectively.
Demonstrated improved net electrical output during discharge operation, with a charging power deviation of 26.308 MW.
