    摘 要:在含数据中心的风光抽蓄互补微电网系统中,数据中心凭借其负荷转移和余热回收特性参与需求响应,能够有效平抑风光出力波动并提升系统经济效益。基于批处理负荷延迟特性建立了工作负荷模型,并综合考虑负荷分配、能耗转移与热量管理建立数据中心能耗模型;结合抽水蓄能电站削峰填谷的能力,构建了以经济效益为目标的数据中心参与风光抽蓄互补微电网优化调度模型,并通过引入 Tent 映射和动态 t 分布变异策略,提出了一种改进的常春藤算法;经算例仿真分析得到风光抽蓄最佳出力、数据中心负荷分配及余热回收等优化结果,验证了所提模型与算法的有效性。

    Abstract: In the wind-solar-pumped storage hybrid microgrid system with data center, the data center participates in demand response by virtue of its load shifting and waste heat recovery characteristics, which effectively smooths out fluctuations in wind and solar power output and improves the economic benefits of the system. Firstly, a workload model is established based on the delayed characteristics of batch processing loads, and a data center energy consumption model is established that comprehensively takes into account load distribution, energy consumption transfer, and heat management. Secondly, integrating the peak shaving and valley filling ability of pumped storage power plants, a data center participation in wind-solar-pumped storage hybrid microgrid optimal scheduling model targeting economic benefits is constructed. And an improved ivy algorithm is proposed by introducing the Tent mapping and dynamic t-distribution variability strategy. Finally,the optimal output of wind-solar-pumped storage and the optimization results of the data center in terms of load distribution and waste heat recovery are obtained through example simulation analysis, which verifies the validity of the proposed model and algorithm.
    Key words: data center; load shifting; waste heat recovery; pumped storage; ivy algorithm; optimal scheduling
