摘要： 分布式冷热电联供系统作为传统分布式供能系统的延伸,在继承传统系统能量分级利用优点的同时,其供能效率和经济性都有很大的提升。为保证系统冷、热、电负荷按照既定的规律变化,维持能量的输出与负荷需求相匹配,确保较高的运行效率,创新地加入储能子系统。本文通过定性分析的方法,针对储能子系统在分布式冷热电联供系统中的作用展开讨论,结合微型冷热电联供系统的模拟结果,对储能子系统进行初步的设计和计算,证明储能子系统的加入对分布式冷热电联供系统的效率和稳定性均有提升。

Abstract: Distributed combined cooling heating and power (CCHP) systems can be regarded as an extension of traditional distributed energy supply system. A CCHP system not only inherits the advantages of the traditional system, but also bring other benefits such as overall energy efficiency and system economy. We consider the use of an energy storage unit in the CCHP system to ensure the system to maintain the energy output and the load demand match, on top of the ability of supplying cold, heat, and electricity load, while maintaining high efficiency. In this paper, the role of the energy storage unit in distributed CCHP systems are discussed and quantified using simulation tools. The results confirmed that the use of an energy storage unit helps enhance the system stability and efficiency.

Key words: combined cooling, energy storage, battery, numerical calculation
