Technical Solution and Economic Analysis for Natural Gas Distributed Energy Unit Combined Cooling and Power Supply of Data Center

  Introduction]  Inorder to improve the reliability requirements and effectively reduce energy consumption, the paper proposes a comprehensive solution for a mains + natural gas distributed energy system and analyze the technical feasibility and economy of the solution, and give support for the choice of the solution.  Method]  To verify the feasibility of the solution, we took a certain data center as example, comparative analyzed the consumption and the distributed energy system of the project.  Result]  The results we obtained demonstrate that compared with conventional data centers, data centers supporting natural gas distributed energy systems have certain advantages in reducing energy consumption. The solution has certain economics, when natural gas prices, cold prices and electricity prices are properly matched.  Conclusion]  The solution and economics this work provided are correct and effective and can provide guidance for investment decisions in natural gas distributed energy projects.
