摘要:

作为数字经济时代的关键基础设施,数据中心的能耗和碳排放问题将日益突出。为全面揭示全球数据中心的研究进展,提出基于综合能源系统视角的知识图谱科学计量方法。该方法从研究趋势、理论方法及工程案例等多维度对数据中心综合能源系统的最新研究进行分析。首先,对全球数据中心能量研究领域科技论文的国际合作情况、分布特征及研究热点进行定性与定量分析。对采用能源梯级利用、多能互补以及源网荷储一体化的数据中心综合能源系统进行研究,并对其规划设计、运行评价、计算求解进行分析。分析发现,数据中心能源系统正不断走向包含经济和低碳的多维度全局优化。最后,鉴于传统数据中心综合能源系统评价指标——电能利用效率(PUE)的局限性,提出了新的评价指标及体系。

Abstract:

As a key infrastructure in digital economy era, the energy consumption and carbon emissions of data centers are becoming increasingly prominent, and a series of research has been conducted by global scholars in the past decade. To comprehensively reveal the progress of global data center energy consumption researches, this article proposes a perspective based on integrated energy system and a metric method based on knowledge graph, and conducts a review of the latest research on the integrated energy system of data center from various aspects such as research trends, theoretical method and engineering cases. Firstly, a qualitative and quantitative analysis is conducted on international collaboration, characteristic distribution, and research hotspots in the field of global data center energy research based on scientific publications. Based on this, the article focuses on the research of data center integrated energy systems, which involve energy cascading utilization, multi-energy complementarity, and source-grid-load-storage integration. It analyzes the planning and design, operational evaluation, computational solution methods, and key points of data center integrated energy systems, revealing that the energy systems of data centers are constantly moving towards multidimensional global optimization that includes economic and low-carbon aspects. Finally, the article discusses the inapplicability of traditional PUE in data center integrated energy systems and preliminarily proposes evaluation indicators and systems for data center energy systems.

Key words: data center, integrated energy system, knowledge graph, PUE, carbon neutrality, multi-energy complementarity, source-grid-load-storage integration
