Problems solved by technology

This patent does not consider the temperature distribution of the entire data center, and only inquires the temperature at points where high temperatures may occur in the computer room; the provided control method only adjusts the temperature of the air conditioner, rather than globally controlling the assignment of tasks and the temperature of the air conditioner in the entire data center

Abstract

The invention relates to a model predication control based energy saving control method of a data center. The method comprises the steps of 1) constructing a quick temperature estimation model of the data center through the fluid dynamics simulation calculation experience based on the internal distribution of the data center; 2) constructing a state space model of the data center according to power models of a server and an air conditioner, an outlet temperature varying model and a quick temperature estimation model; 3) proposing a mode predication control scheme applicable to the data center based on the state space model; 4) predicating the task quantity of the data center through an AR model, predicating the calculation load of the data center in the future, predicating and controlling the MPC (model predication control) scheme by model to perform optimal control for each device in the data center according to the predicated task quantity. Compared with the prior art, the method has the advantages that the inlet / outlet air temperature of a key assembly of the data center can be quickly and accurately estimated, the verification and use are easy, and the practicability is high.

Description

technical field [0001] The invention relates to a data center energy-saving control method, in particular to a data center energy-saving control method based on model predictive control. Background technique [0002] A data center refers to a computer room used to place servers in the field of communication and information technology. With the rapid development of modern computer and Internet technology, data centers play a pivotal role in all walks of life. However, heat dissipation and cooling of equipment such as servers in the computer room consume a large amount of electric energy. The problem of energy consumption gave birth to the concept of green data center. In the construction of green data centers, high-efficiency computing equipment, emerging cooling technologies, and basic measures to reduce data center energy consumption and improve energy efficiency. At the same time, for the existing data center, optimizing the operation status of various equipment and coo...
