Power-grid-friendly data center refrigeration system control method and system

Abstract

The invention discloses a power-grid-friendly data center refrigeration system control method and system. A machine room is divided into a plurality of subspaces in advance, and each subspace comprises a plurality of servers and refrigeration equipment; the total server power consumption of each subspace is obtained; according to the principle that the lower the total power consumption of the servers is, the higher the priority for turning off the refrigeration equipment is, the priority of the total power consumption of the servers of each subspace is ranked; and a real-time power supply energy consumption value of a power grid is acquired,whether energy consumption supply is sufficient or not is judged according to the real-time power supply energy consumption value of the power grid, if the energy consumption supply is sufficient, the refrigeration equipment of the subspace is not turned off, closing the refrigeration equipment of the corresponding subspace is turned off according to a priority ranking result until the energy consumption supply is judged to be sufficient. According to the control method and system,when the refrigerating capacity of the refrigerating systems needs to be closed due to insufficient power supply of the power grid, the task load is judged according to the IT power consumption of different regional servers, so that a regional refrigerating system with less task load is turned off in a limited manner, and the influence of refrigeration turning off on the stability is reduced to the maximum extent.

Description

technical field [0001] The invention relates to a grid-friendly data center cooling system control method and system, belonging to the technical field of automatic control. Background technique [0002] Refrigeration equipment accounts for about 40% of the total energy consumption of the data center, and the huge energy consumption places a heavy burden on the power grid, resulting in the power grid often being unable to guarantee timely power supply. When the energy supply is insufficient, the refrigeration equipment needs to be adjusted frequently or even shut down, so it is very important to choose the appropriate shutdown sequence of the refrigeration equipment. [0003] When the power supply of the data center is insufficient, it is usually impossible to reduce the power consumption of the cooling system in each room uniformly. When the power supply of the data center is insufficient, the computer room needs to take measures to reduce energy consumption. A common appr...

Problems solved by technology

Since the power consumption and business volume of servers in different private rooms are different, their cooling requirements are also different. Therefore, if the operator reduces the cooling capacity on average, the private room with a relatively large business load will definitely have a risk of overheating
