摘　　要：针对天然气管网压力能未被充分利用且应用场景适应性不足等问题,在数据中心高能耗、碳污染问题日益突出的背景下,提出一种含天然气压力能综合利用的数据中心供能系统优化运行方法。首先,设计了考虑天然气压力能发电制冷综合利用的数据中心供能系统架构。然后,基于(火用)分析理论建立了天然气压力能发电、制冷出力特性模型,考虑数据中心IT设备能耗以及散热特性,建立了数据中心电功率需求模型和冷功率需求模型。其次,综合考虑配电网供能约束、燃气轮机、吸收式制冷机功率约束和电池充放电功率约束,以日运行费用最低为目标函数构建优化调度模型。最后,根据西南地区某天然气调压站、某A级数据中心能耗需求数据设置算例进行仿真,验证了所提系统方案及优化方法的可行性和经济性。Aiming at the problems that the pressure energy of natural gas pipeline network is not fully utilized and the adaptability 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 consumption 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 objective 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.
