分布式能源系统配置优化
摘要:为了解决燃气能源一次利用率低且系统产能与用户负荷需求存在供需差异的问题，提出利用能流分析方法优化分布式能源系统。分析了以燃气轮机和内燃机为主的典型分布式能源系统结构模型，在“以热定电”和“以电定热”这2种配置方式下，不同季节、不同热(冷)电比、不同发电效率对一次能源利用率的影响。无论系统的产能与用户负荷需求比例怎样，无论采用那种分配方式，夏季的平均一次能源利用率高于春、秋、冬季的平均一次能源利用率。
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.
