摘　　要：综合能源系统作为数据中心节能减排的重要路径及手段,目前其优化与评价目标单一且不全面,成为提高数据中心可持续水平的阻碍.为全面优化数据中心综合能源系统可持续性,借鉴生态学分析中的能值理论,首次提出计及能值可持续性的系统优化目标.首先,建立数据中心综合能源系统规划和调度优化模型,并采用NSGA-Ⅱ算法,以经济、碳排为目标进行多目标优化,以能值可持续性指数为目标进行单目标优化.对4种方案的优化结果,从能值结构、能值指标、能值流等方面进行对比分析.结果表明:以ESI为优化目标的数据中心综合能源系统方案,其能值可持续性指数值为0.4238,高于其他3种方案,可持续性较好,同时其年成本为16199万元,年碳排为36236吨.此外,结合数据中心现有常见评价指标,分析强调了构建数据中心综合能源系统综合评价体系的重要性.Serving as a crucial pathway and means for data centers to achieve energy conservation and emission reduction,the integrated energy system is currently empty of optimization and evaluation goals,and incomprehensive,hindering the improvement of its sustainability.To fully optimize the sustainability of data center integrated energy system,in this study,a system optimization goal for the energy sustainability was proposed for the first time using the energy theory from ecological analysis for reference.Firstly,an optimization model was established for the planning and scheduling of data center integrated energy system.And,multi-objective optimization was arranged to conducted using the NSGA-II algorithm with economic and carbon emission goals,and single-objective optimization was conducted taking the energy sustainability index as the target.Four optimization results were compared in terms of energy structure,indicators,and flow.The results show that the scheme optimized with energy sustainability index(ESI)as the target can yield ESI value of 0.4238,being higher than the other three schemes and possessing better sustainability.At the same time,its annual cost is 161.99 million yuan and its annual carbon emissions are 36,236 tons.Additionally,in conjunction with existing common evaluation indicators for data centers,the analysis emphasizes the importance of developing an integrated assessment framework for data center integrated energy system.
