Research shows that the price of natural gas yields the greatest impact on both the energy systems,followed by electricity price and asset investment,but cold and hot selling price produces minor influence. Gas engine energy supply system has more advantages in regions with lower user load heat /power ratio,and has higher project anti-risk capability. The research results can provide reference to the techni- cal selection and scheme configuration of distributed energy supply system.
