Abstract

In order to enhance the flexibility of biomass power plants

the technology of existing biomass power plants coupled with energy storage was investigated

and a novel energy storage system coupling biomass power generation with heat pump energy storage was proposed. A model and relevant evaluation indexes were established

and the influence of key parameters on system performance was analyzed. Results indicate that the system with better performance can be obtained by improving the effectiveness of heat exchangers

and improving the isentropic efficiencies of compressors and expanders. Taking a biomass power plant with the rated power of 12 MW

main steam temperature of 540 ℃

and feedwater temperature of 220 ℃ as a research example

for the established biomass-heat pump energy storage system with the isentropic efficiencies of compressor and expander of 0.88

ambient temperature of 30 ℃

external heat exchanger effectiveness of 0.984 6

and regenerator effectiveness of 0.975 0

the coefficient of performance (COP) of system and the cycle efficiency can achieve 1.423 and 50.09%

respectively. This study can provide a theoretical basis for the technological transition of biomass power plants to energy storage operation.
