1. A power grid-friendly control method for a data center cooling system, comprising:
dividing an equipment room into a plurality of pieces of subspace in advance, with a plurality of servers and a cooling device comprised in each piece of subspace;
obtaining total power consumption of the servers in each piece of subspace;
performing priority sorting on the total power consumption of the servers in each piece of subspace based on a principle that lower total power consumption of the servers leads to a higher priority of turning off the cooling device; and
obtaining a real-time power supply energy consumption value of a power grid; determining, based on the real-time power supply energy consumption value of the power grid, whether an energy supply is sufficient; when the energy supply is sufficient, skipping turning off the cooling device in the subspace; and when the energy supply is not sufficient, turning off a cooling device in corresponding subspace based on a priority sorting result, till it is determined that the energy supply is sufficient;
wherein the obtaining a real-time power supply energy consumption value of a power grid; determining, based on the real-time power supply energy consumption value of the power grid, whether an energy supply is sufficient; when the energy supply is sufficient, skipping turning off the cooling device in the subspace; and when the energy supply is not sufficient, turning off a cooling device in corresponding subspace based on a priority sorting result, till it is determined that the energy supply is sufficient, comprises:
obtaining a real-time supply voltage Vreduced of the power grid and a preset supply voltage Vstandard in the case of normal power supply;
when the real-time supply voltage Vreduced of the power grid is not less than the preset supply voltage Vstandard in the case of normal power supply, skipping turning off the cooling device in the voltage subspace; or when the real-time supply voltage Vreduced of the power grid is less than the preset supply voltage Vstandard in the case of normal power supply, calculating a power consumption reduction value voltage ΔPreduce according to the following formula:
