Abstract

According to the limitations of indicators in the current energy utilization performance evaluation method for the distributed energy system

the energy utilization in the distributed energy system was investigated by adopting the equivalent energy consumption analysis method

taking agas-steam combined cycle system as the research object.The results show that

from the aspect of the comparable coefficient of performance

the energy saving ability of the cooling/heating link of the distributed energy system is better than that of the conventional one.From the aspect of the equivalent power consumption of the cooling/heating link

in the distributed energy system

reducing the extraction steam temperature for the absorption refrigerating machine is an effective way to improve the system performance.
