Title:
POWER GRID-FRIENDLY CONTROL METHOD AND SYSTEM FOR DATA CENTER REFRIGERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/267277
Kind Code:
A1
Abstract:
Disclosed are a power grid-friendly control method and system for a data center refrigeration system. The method comprises: dividing in advance a computer room into a plurality of subspaces, each subspace comprising a plurality of servers and a refrigeration device; obtaining the total power consumption of the servers in each subspace; prioritizing the total power consumption of the servers in each subspace according to the principle that the lower the total power consumption of a server the higher the priority thereof in the shutdown of a refrigeration device; obtaining a real-time power supply energy consumption value of a power grid; according to the real-time power supply energy consumption value of the power grid, determining whether energy supply is sufficient; if so, then not shutting down the refrigeration devices in the subspaces; or otherwise, shutting down a refrigeration device of a corresponding subspace according to the prioritization result, until it is determined that the energy supply is sufficient. Advantages: when the refrigeration capacity of a refrigeration system needs to be shut down due to insufficient power supply in a power grid, the amount of tasks thereof is determined according to the IT power consumption of servers in different regions, thereby limitingly shutting down refrigeration systems in regions having less tasks, and minimizing the impact of refrigeration shutdown on stability.
