为促进数据中心综合能源系统的节能减排与高效用能,提出了一种考虑数据中心余热回收且兼顾经济性与碳排放的电-热-氢综合能源系统多目标优化调度方法。首先,分析数据中心的工作特性,建立数据中心的功耗模型、热力模型以及余热回收模型。基于综合能源系统结构,考虑电-热-氢多能耦合特性,建立系统内部各能量转化设备的运行模型。在此基础上,以最小化系统总运行成本与碳排放量为目标,构建多目标日前优化调度模型。针对所提多目标优化问题,采用规划法向约束生成法(normalized normal constraint,NNC)进行高效求解,获取均匀的Pareto前沿点,再从中选择最佳折衷解作为系统调度方案。最后,以某数据中心综合能源系统为例进行仿真分析,结果表明,所提多目标优化调度策略可以有效兼顾综合能源系统运行的经济性和低碳性,同时NNC法能够确保折衷解的质量,验证了所提模型和方法的有效性。
