Optimizing the Operation of Data Center Energy Supply Systems Considering the Utilization of Pressure Energy
Aiming at the problems that the pressure energy of natural gas pipeline network is not fully utilized and the adapt-ability of application scenarios is insufficient,a data center energy supply optimization method with comprehensive utilization of natural gas pressure energy is proposed under the background of the increasingly prominent problems of high energy con-sumption and carbon pollution in the data center.Firstly,the data center energy supply system architecture considering the comprehensive utilization of natural gas pressure energy for power generation and refrigeration is designed.Then,based on the exergy analysis theory,the power generation and refrigeration output characteristic models of natural gas pressure energy are established.Considering the energy consumption and heat dissipation characteristics of IT equipment in the data center,the power demand model and cold power demand model of the data center are established.Secondly,considering the energy supply constraints of distribution network,the power constraints of gas turbines,absorption chillers and battery charging and discharging power constraints,the optimal scheduling model is constructed with the minimum daily operating cost as the ob-jective function.Finally,the simulation is carried out according to the energy consumption demand data setting example of a natural gas pressure regulating station and a class A data center in Southwest China,which verifies the feasibility and economy of the proposed system scheme and optimization method.
