Abstract

In view of the high cost of the current solar thermal power generation system and the large fluctuation of photovoltaic power generation

a photovoltaic-tower photothermal supercritical carbon dioxide Brayton cycle(SCO

)hybrid power generation system is proposed

and the influence law of the key configuration parameters of the system on economical efficiency and environmental protection performance is studied. The multi-objective optimization of system parameter configuration is carried out based on different load types

and the operating charact

eristics of the hybrid power generation system under different application scenarios are explored. The simulation results show that when the ratio of solar thermal power generation in the hybrid power generation system increases

the economical efficiency of the system decreases

but the environmental protection performance improves. Increasing the total fixed power of the hybrid power generation system can reduce the system's levelized cost of energy. When the solar multiple is 4 and the heat storage time is 18 h

the minimum value of the levelized cost of energy is 0.64 yuan/(kW·h)

which is 31% higher than the economical efficiency of solar thermal power generation alone. Under isolated grid operation conditions

the addition of diesel generator sets to the hybrid power generation system can effectively improve the power supply reliability of the solar power generation system. When the proportion of diesel power generation is only 1.5%

and the annual operation time of diesel generator sets is less than 200 h

all the real-time power load demand will be met.
