Abstract

This paper presents a solar power tower generation system consisting of a supercritical carbon dioxide power cycle

a free-falling particle receiver

and a particle dual-tank thermal storage system. The objective is to achieve the maximum efficiency and the minimum levelized cost of electricity. Thermodynamics and economic models are developed

and key parameters of each subsystem

including the turbine inlet temperature

receiver aperture size

and temperature difference of thermal storage system

are analyzed. The results show that the highest overall efficiency

reaching 25.61%

is achieved when the turbine inlet temperature is 680 ℃

the receiver aperture size is 22 m ×22 m

and the temperature difference is 231 ℃. However

the lowest levelized cost of electricity

which is 0.7726 yuan/kWh

is attained when the turbine inlet temperature is 620 ℃

the receiver aperture size is 18 m ×18 m

and the thermal storage utilization temperature difference is 331 ℃.
