A data center renewable energy smooth power supply method

Abstract

The invention discloses a renewable energy source smoothening power supply method for a data center. A renewable energy source smoothening module obtains the optimal charging-discharging scheme of power supply storage equipment by solving a nonlinear constraint optimization problem, so that the renewable energy source which is used for supplying energy for the data center finally can be in the minimum fluctuation in each time frame (such as one hour); and a load adaptive module is a load delay scheme based on a greedy algorithm, and on the basis of the renewable energy source smoothening, an effect of maximum utilization of the renewable energy source is realized by deploying the delayed load. By adoption of the method, the fluctuation property of the renewable energy source can be effectively relieved, and maximum utilization of the renewable energy source can be realized in the stable supply condition of the renewable energy source.

Description

technical field [0001] The invention belongs to the technical field of data center energy consumption, and more specifically, relates to a method for smoothing power supply of renewable energy in a data center. Background technique [0002] With the continuous development of cloud computing technology, the computing power and scale of the data center are growing rapidly, and the subsequent high-power energy consumption has brought two serious consequences: First, the purchase of electricity by the data center will bring huge electricity bills Secondly, data centers currently still mainly rely on obtaining energy from the grid, which generates most of the power by burning carbon-intensive fossil fuels. Huge energy consumption will lead to negative environmental impacts and accelerate the global greenhouse effect. [0003] Due to the low cost and non-polluting characteristics of renewable energy (such as wind energy and solar energy), more and more companies have begun to buil...

Problems solved by technology

However, renewable energy power supply also brings new challenges to data centers: (1) The volatility of renewable energy will challenge the stability of power grids and data centers, and frequent switching of energy sources will also increase operating costs; (2) Intermittent nature of renewables reduces utilization

[0004] However, most of the existing solutions are unable to deal with the first challenge, ignoring the impact of fluctuating renewable energy supply on the grid and data centers, and some work adopts the practice of fully storing renewable energy in power storage devices to eliminate volatility, but this requires huge battery capacity
