Abstract

[Objective

]

This paper aims to reduce carbon emissions and enhance the operational flexibility of coal-fired power units. [Methods

]

A coupled system integrating compressed air energy storage(CAES) with oxygenenriched coal-fired units was proposed based on energy complementary utilization principles. Various coupling sch

emes were proposed

and the thermodynamic performance and economic feasibility of the integrated system were analyzed. [Results

]

The results show that by replacing steam turbine extraction with flue gas waste heat to preheat the turbine inlet air

when the heat exchange efficiency of HE1–HE3 is 89% and turbine inlet temperature is raised to 115 ℃

the round-trip efficiency of the CAES system can reach a maximum of 74.33%

representing a 24.25% improvement over the standalone CAES system. When carbon allowances

revenue

and carbon taxes are considered

the coupled system achieves a static payback period of 11.256 years

shorter than that of the conventional unit. In this case

the net present value(NPV) and internal rate of return(IRR) reach 801.73 million yuan and 9.63%

respectively

both exceeding those of the conventional system

indicating better economic performance. Carbon taxes increase the levelized cost of electricity(βLCOE) of the coupled unit

while carbon allowance trading and CO

sales significantly reduce the βLCOE. The βLCOE of the coupled unit becomes lower than that of the conventional unit when the carbon tax

carbon allowance price

and CO

price exceed 6.4 yuan/t

73.9 yuan/t

and 14.68 yuan/t

respectively. Sensitivity analysis reveals that coal price has the greatest impact on the economic performance of the coupled unit

followed by the carbon allowance price

price

and carbon tax. [Conclusion

]

The proposed low-carbon pathway for the deep integration of thermal power and energy storage offers theoretical and engineering guidance for promoting low-carbon emissions from coal-fired power units and accelerating their transition into flexible

dispatchable power sources under the framework of a new power system.
