新能源接入为解决数据中心高耗能和运行费用问题提供了有效方案。但与传统供电模式相比,新能源具有间歇性、随机性,当此类能源出力接入数据中心园区后,不仅影响数据中心各类设备的正常运行、园区供电可靠性,同时也对主网运行的稳定性造成不利的冲击。通过分析数据中心组成结构特征,及各类用户请求任务特性发现,数据中心服务器集群负荷具有可调控性,并配合园区冗余不间断电源(uninterruptible power system,UPS)储能系统,提出一种新的数据中心联络线功率控制方法,建立基于任务延时机制的服务器集群负荷模型,建立服务器集群可控负荷需求侧响应模型和UPS需求侧响应模型,基于模型提出数据中心园区联络线功率控制方法,在保证用户服务质量和供电可靠性的前提下,通过动态调整服务器集群负荷和UPS蓄电池组的荷电状态有效平抑数据中心园区联络线功率波动。最后通过实验验证了所提方法的有效性,并分析各参数对功率波动平抑效果的影响。 New energy access provides an effective solution to the data center’s high energy consumption and operating costs. However, compared with the traditional power supply mode, the new energy is intermittent and random. When such energy resources are exported to the data center park, it not only affects the normal operation of various data center equipment and the power supply reliability in the park, but also affects the main network The stability of the operation has an adverse impact. By analyzing the structure of the data center and the request of various users, we found that the cluster load of the data center server is regulable, and combined with the park uninterruptible power system (UPS) energy storage system, a new type of new , A server cluster load model based on task delay mechanism is established, a controllable load demand side response model and a UPS demand side response model are established, and a power control method of the data center park line is proposed based on the model. Under the premise of ensuring user service quality and power supply reliability, power fluctuation of the tie line in the data center park can be effectively stabilized by dynamically adjusting the server cluster load and the state of charge of the UPS battery pack. Finally, the validity of the proposed method is verified by experiments, and the influence of each parameter on the power fluctuation stabilizing effect is analyzed.
