Scientific planning of data center energy systems can achieve energy conservation and carbon reduction, and orderly achieve” dual control” of energy consumption and” dual carbon” of society. However, existing planning research mainly focuses on pure electrochemical energy storage, without considering new energy storage modes of hydrogen electric coupling. Meanwhile, there are few studies that use pure green energy supply as a guide to integrate energy and storage resources for planning and modeling. Based on the concepts of green energy supply and hydrogen electricity coupling, the storage, conversion, and balance of multiple energy sources including electricity, heat, and cold were analyzed. A data center energy system optimization configuration model, including photovoltaic power generation, hydrogen energy storage, and electrochemical energy storage, was constructed from two dimensions: reducing costs and reducing external energy dependence. The numerical results show that compared with pure electrochemical energy storage, the new energy storage planning scheme based on hydrogen electric coupling has lower economic cost and external energy dependence, and the proposed model has a good realistic matching degree.
