Abstract

To solve the problem of low utilization rate of gas energy and the difference between supply and demand of system capacity and user load demand, this paper proposes a method of energy flow analysis to optimize the analysis of distributed energy systems. The structural model of typical distributed energy system based on gas turbine and internal combustion engine is analyzed. The different seasons and different heat (cold) electrical ratio are analyzed under the two configurations of ‘determining electricity by heat' and ‘determining heat by electricity’， as well as the impact of different power generation efficiency on primary energy utilization. Regardless of the ratio of system capacity to user load demand, regardless of the distribution method, the average primary energy utilization rate in summer is higher than that in spring, autumn or winter.

Key words
