Abstract

The impact of incentive policies on the biomass gas-driven combined cooling, heating and power (BGDCCHP) system was investigated to promote its development through optimal policies. An optimization model on the BGDCCHP system considering incentive policies, including feed-in tariff, capital subsidy, low interest loan and carbon emission trading, was established to maximize the annual total cost saving ratio (ATCSR), annual primary energy consumption saving ratio (APECSR) and annual CO2 emission reduction ratio (ACDERR) compared with the reference system. Based on a hotel building, the optimal configuration and performance of the BGDCCHP system operating following electric load (FEL) and following thermal load (FTL) for various incentive policies were analyzed. Results show that the impact of operating strategies on the equipment capacity is greater than that of incentive policies. The impact of capital subsidy, low interest loan and carbon emission trading on the economic and comprehensive performance under FEL is greater than that under FTL, whereas such impact on the energetic and environmental performance under FTL is greater. When the optimal incentive policies are implemented, the ATCSR, APECSR and ACDERR under FEL and FTL reach 68.741%, 71.852%, 92.881%, 95.049%, 94.880% and 96.947%, respectively, indicating that FTL yields better performance compared with FEL.
