Data center multiple energy guarantee triple generation system and control method thereof

Abstract

The invention discloses a data center multiple energy guarantee triple generation system and a control method thereof, and belongs to the field of energy optimization. The data center multiple energyguarantee triple generation system includes a gas turbine power generation system, a steam turbine power generation system and a city power grid which are connected to the data center through a secondAC bus; an electric vehicle battery changing station and the city grid are connected to a first AC bus; the first AC bus and the second AC bus are connected by a grid-connected switch; lithium bromide refrigerating machines and electric refrigerating machines produce cold energy; and a high-temperature flue gas splitter realizes the split control of flue gas. The data center multiple energy guarantee triple generation system supplements the waste heat boiler-steam turbine power generation system, splits the high-temperature flue gas produced by the gas turbine, and adjusts the ratio of the cold energy and electric power output by the triple generation system, so as to adapt to the demand ratio of cold energy and electric energy of the data center, and realize the cascade utilization of the energy at the same time. The invention considers that the data center is constructed relying on the electric vehicle battery changing station, and uses the power batteries of the battery changing station as a reliable energy storage device for the data machine room, which provides further guarantee for the stable power supply of the data center.

Description

technical field [0001] The invention belongs to the technical field of energy optimization, and in particular relates to a data center multiple energy guarantee triple supply system and a control method thereof. Background technique [0002] The combined cooling, heating, and power supply system with gas turbines as the core, using natural gas as distributed energy, eliminates the construction of large-capacity long-distance transmission high-voltage transmission lines, and reduces the power loss caused by long-distance transmission lines. Natural gas is a pure and environmentally friendly high-quality energy source, which contains almost no sulfur, dust and other harmful substances. The carbon dioxide produced during combustion is lower than that of other fossil fuels, so it can fundamentally improve the quality of the environment. [0003] The combined cooling, heating and power supply system can provide users with three forms of energy: cooling, heating and electricity at...

AI Technical Summary

Problems solved by technology

It is mentioned in the literature that the cooling-to-power ratio of a gas turbine-based triple power supply system is generally 1.4, and the total cooling-to-power ratio of a data center in North China is about 0.87 in summer. The capacity of power generation will not be able to meet the needs of the power load of the data center, and the insufficient part of power generation can be supplemented by city power

Using the mode of cooling and constant power can make full use of the generator set, and the overall economic efficiency of the system is high. However, if the mains power is completely interrupted, the power generation capacity of the triple power supply system cannot meet the overall power consumption capacity of the data center, and the reliability of the system is slightly lower.
