数据中心园区能源互联网的关键技术与发展模式
Key Technologies and Development Modes of Park Energy Internet in Data Centers
数据中心作为“新基建”的重要方向之一，其节能降耗问题一直是领域的研究重点。园区能源互联网注重清洁能源消纳，强调能源利用效率的提升，其“源–网–荷–储–充”的协调技术是提升数据中心能效的关键，探索数据中心园区能源互联网的关键技术与发展模式具有现实意义，然而目前数据中心与园区能源互联网的研究各自独立，技术之间缺乏相互结合。本文针对目前两者融合研究的领域空白，首先分析了数据中心与园区能源互联网技术的结合点，探讨其在设备规划、直流配电、余热回收、多能调度、负荷管理以及储能调度6 方面的关键技术与融合方向。在此基础上提出数据中心园区能源互联网的基本建设架构，对商业与运营模式进行论证，并展望领域未来发展的重点。最后，针对我国数据中心园区能源互联网的进一步发展提出建议，技术融合、试点实践、政策扶持及三者的有机结合是保障发展的关键。
Data center is one of the important directions of the New Infrastructure initiative, and the energy efficiency of the data centers has always been a focus of research. Park Energy Internet (PEI) is a system that emphasizes the consumption of clean energy and the promotion of energy efficiency. The “generation, grid, load, storage, and charging” coordination technology of PEI will be the key to improving the energy efficiency of data centers. So exploring the key technologies and development modes of PEI in data centers will be significant. However, the current research on data centers and PEI is independent to each other. Therefore, this study analyzes the integration of data centers and PEI, and discusses the key technologies in equipment planning, DC power distribution, waste heat recovery, multi-energy dispatch, load management, and energy storage dispatch. On this basis, we proposes the infrastructure framework of the PEI in data centers, explores its business models, and prospects the priority of further development. Finally, suggestions for the further development of the PEI in data centers in China are proposed; technology integration, pilot practice, and policy support are the key elements which promote its development.
