| 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. |
