Research on Energy Availability and Economy Coupling of Distributed Energy Supply System in Data Center

In recent years, the distributed energy supply system of the data center has become a hot topic in the industry, and the research on the coupling relationship between energy supply availability and economy is still insufficient. The thesis takes Hangzhou as an example to establish a mathematical model of coupling the energy supply cost and energy supply availability of the data center distributed system and checks it. The results show that the distributed energy system has the best economy and meets the energy supply availability requirements of the data center when the installation matching and system design are carried out according to the cooling and electric loads of the data center. In order to improve the reliability of the energy supply system in the data center, the prime mover of the gas distributed system should be equipped with one standby machine. At this time, the main limiting factor limiting the availability of the distributed energy supply system in the data center is the reliability of the gas supply network. The availability of two or more standby units does not significantly improve the availability of distributed energy supply system but increases the unit energy supply cost of the system.
