| 摘要: |
| 互联网数据中心体量大、能耗高，近年来逐渐成为节能降耗的重点领域。基于对数据中心用电需求特征和电网电价机制的分析，提出一种基于经济性的互联网数据中心光伏和储能电池协同优化配置模型。通过该模型求得光伏和储能电池的最优配置方案，以降低数据中心的运行成本。该方案使得数据中心对当地电网电力具有较低的依赖性，充分利用了光伏供应的电力。仿真实例表明，在数据中心结构、负荷和运行环境相同的情况下，该方案可以有效降低数据中心的运行成本，具有较高的实用化价值。 |

| Abstract: |
| In recent years, the large internet data center with high energy consumption has gradually become the key area of energy saving. Based on the analysis of electricity demand characteristics and the electricity price mechanism in a data center, a collaborative optimal configuration model of photovoltaic and energy storage battery based on economic dispatch is proposed. Through this model, the optimal configuration scheme of photovoltaic and energy storage battery is obtained to reduce the operational cost of a data center. The scheme ensures that the data center is less dependent on the local power grid and makes full use of the photovoltaic power supply. A simulation example reveals that, in the same data center structure, load and operating environment, the scheme has effectively reduced the operating cost of the system and has high practical value.
