Abstract

Abstract: In order to acquire the parameters with higher impacts on the energy efficiency, economical efficiency and environment economy of the gas-fired distributed energy for the purpose of supervising the construction and operation of the projects, in this paper the efficiency calculation and sensitivity analysis model is established in terms of the thermal performance, engineering economy and environmental performance of the gas-fired distributed energy resource system. In addition, a case study of the gas-fired distributed energy project for an international airport is conducted. The results show that the improvement in power generation efficiency and cooling system COP are helpful for the substantial increase in primary-energy-saving rate. The prices of natural gas and cold have greater impacts on system economy and should be given full consideration in the design and application of gas-fire distributed energy projects. NOx and SO2 have significant impacts on the emission reduction income while CO2 has greater impact on the environment.

Key words: gas distributed energy, energy efficiency calculation model, multi-objective parameter, sensitivity analysis
