数据中心引入新能源供电以实现绿色低碳运行。然而,新能源的波动性和随机性导致其难以被数据中心高效利用。数据中心主要热介质呈现出吸收、释放热量并延缓温度变化的储冷能力,为制冷系统灵活调整功耗提供基础。为克服现有数据中心热力学模型难以描述整体热力学过程的不足,建立基于Sage-Husa型卡尔曼滤波器的数据中心热力学动态估计(SDTD)模型;为实现制冷系统高水平消纳新能源,基于SDTD模型提出一种最大化消纳新能源的制冷系统变温运行策略,采用模型预测控制方法动态设定制冷系统运行温度,进而调整制冷系统功耗以主动匹配新能源出力。实验结果验证了所提SDTD模型的准确性以及所提变温运行策略的有效性,实现了制冷系统能耗与新能源的优化匹配,提高了新能源消纳率。
The data center introduces renewable energy power supply to achieve green and low-carbon operation. However
the fluctuation and stochasticity of renewable energy make it difficult to be efficiently utilized by data centers. The primary thermal medium in data centers exhibits cold storage capability to absorb and release thermal energy while delaying temperature changes
providing a foundation for flexible power consumption adjustment for cooling system. To overcome the limitations of existing thermodynamic models of data centers in describing overall thermodynamic processes
a Sage-Husa Kalman filter based data center thermodynamic dynamic estimation (SDTD) model is proposed. To enable high-level renewable energy accommodation in cooling systems
a variable-temperature operation strategy is proposed based on the SDTD model to maximize the renewable energy accommodation. The model predictive control method is used to dynamically adjust the operation temperatures of cooling system
thereby adjusting power consumption to actively match the output of renewable energy. Experimental results validate the accuracy of the proposed SDTD model and the effectiveness of the proposed variable-temperature operation strategy
achieving optimal alignment between cooling energy consumption and renewable energy while improving the renewable energy accommodation rate.
