分布式能量系统的案例分析

Research on distributed energy system

通过分布式能量系统与传统大电网集中供电方式的比较,系统分析了分布式能量系统的特点。以一办公大楼为例,分析了该大楼分别采用分布式能量系统方案和传统供能方案的经济性。在现有的电力市场条件下通过改变机组造价和天然气价格等,对分布式能量系统进行了敏感性分析,进一步分析了分布式能量系统具有的经济性优势,论证了它与大电网供电的相互补充关系。由于实现了能量的梯级利用等,分布式能量系统具有其先进性。

Based on the comparison of the power supply methods of the distributed energy system and the traditional great grid center, the properties of distributed energy system are analyzed. An office building is used as the object. The economy of the two schemes is calculated. Through the sensitivity analysis of unit cost and natural gas price on the present power market, the economy of distributed energy system is studied. The supplementary relationship between these two systems is analyzed.
