【摘要】 采用清洁高效、环保节能的综合能源系统替代传统供能系统，是实现数据中心绿色可持续发展的有效措施。综合能源系统的设计与运行优化通常被分割成两个阶段进行考虑，而并未实现系统的最优规划。基于数据中心全年能耗特点，设计了一种以天然气、太阳能及地热能为能源，集成有机朗肯循环发电系统、吸收式制冷机组、换热器等余热利用设备的综合能源系统。以投资成本、运行成本、碳税成本及太阳能丢弃惩罚成本等在内的综合成本为优化目标，建立了综合能源系统混合整数线性规划模型，对各设备容量以及调度策略进行了集成优化。以某小型数据中心为例进行了案例研究，结果显示：与传统供能方式相比，所构建的综合能源系统费用年值节约率为35.72%,二氧化碳减排率为55.11%,一次能源节约率为39.86%。更多还原

【Abstract】 Adopting the energy-efficient, clean and environmental friendly integrated energy system(IES) in data center to replace conventional separate production system is one of effective alternatives to realize the green and sustainable development of data center. The system configurations and operations of IES were respectively optimized in the traditional methods. Based on the annual energy consumption characteristics of the data center, a comprehensive energy system was designed, which uses natural gas, solar energy and geothermal energy as energy sources and integrates organic Rankine cycle power generation system, absorption refrigeration unit, heat exchanger and other waste heat utilization equipment. Taking investment cost, operation cost, carbon tax cost and solar energy discarding penalty cost as optimization objectives, a mixed integer linear programming model for integrated energy system was established, and the capacity of each equipment and scheduling strategy were integrated and optimized. A case study in small-scale data center was conducted, and the results demonstrate that the optimized IES achieves the annual total cost saving rate of 35.72%, carbon dioxide emission reduction rate of 55.11%, and primary energy saving rate of 39.86%.更多还原
