Abstract

To solve the problem of deep peak regulation for flexibility faced by thermal power units

a scheme of coupling the adsorption compressed CO

energy storage (AB-CCES) system with thermal power units to achieve flexibility retrofit was proposed. The impact of the thermal-electric co-storage/co-supply characteristics of the AB-CCES system on the efficient storage/utilization of electrical and thermal energies in thermal power units was investigated. Thermodynamic research results show that the round-trip efficiency and energy storage density of the AB-CCES system under the constant pressure operation mode are 84.45% and 6.06 kWh/m

respectively

while those under sliding pressure operation mode are 89.62% and 5.93 kWh/m

respectively. Under the 50% of turbi

ne heat acceptance (THA) load in a thermal power unit

the maximum regulation ranges during load increase/decrease stages of this integrated system are 16.36%

(

is the rated load) and 10.6%

respectively. However

the thermodynamic performance of the integrated system presents a slight decline compared with that of the thermal power unit.
