【摘要】：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。
[Abstract]:New energy access provides an effective solution to the problem of high energy consumption and operating costs in data centers. However, compared with the traditional power supply mode, new energy sources are intermittent and random. When this kind of energy is connected to the data center park, it will not only affect the normal operation of all kinds of equipment in the data center, but also the reliability of power supply in the park. At the same time, it also has a negative impact on the stability of the main network. By analyzing the structural characteristics of the data center and all kinds of user request task characteristics, it is found that the load of the data center server cluster is controllable. And with the park redundant uninterruptible power system UPSs energy storage system. A new data center tie-line power control method is proposed, and a server cluster load model based on task delay mechanism is established. The demand side response model of server cluster and the demand side response model of UPS are established. Based on the model, the power control method of tie-line in data center park is proposed. On the premise of guaranteeing the quality of service and the reliability of power supply. The dynamic adjustment of the server cluster load and the charging state of the UPS battery can effectively suppress the power fluctuation of the tie-line in the data center park. Finally, the effectiveness of the proposed method is verified by experiments. The influence of the parameters on the power fluctuation is analyzed.
