Abstract
Modern smart grids have proposed a series of demand response (DR) programs and encourage users to participate in them with the purpose of maintaining reliability and efficiency so as to respond to the sustainable development of demand-side management. As a large load of the smart grid, a datacenter could be regarded as a potential demand response participant. Encouraging datacenters to participate in demand response programs can help the grid to achieve better load balancing effect, while the datacenter can also reduce its own power consumption so as to save electricity costs. In this paper, we designed a demand response participation strategy based on two-stage decisions to reduce the total cost of the datacenter while considering the DR requirements of the grid. The first stage determines whether to participate in demand response by predicting real-time electricity prices of the power grid and incentive information will be sent to encourage users to participate in the program to help shave the peak load. In the second stage, the datacenter interacts with its users by allowing users to submit bid information by reverse auction. Then, the datacenter selects the tasks of the winning users to postpone processing them with awards. Experimental results show that the proposed strategy could help the datacenter to reduce its cost and effectively meet the demand response requirements of the smart grid at the same time.

We aim to reduce the total cost of the datacenter by involving the datacenter to participate in demand response program provided by the smart grid and in turn to improve the sustainability of the demand side of the grid
We proposed a two-stage datacenter demand response strategy towards the smart grid environment. e first stage is the interaction between the smart grid and the datacenter, which mainly includes the grid sending DR signals to the datacenter according to real-time electricity load
Summary
With the development of the world economy and the depletion of natural resources, energy crisis and environmental pollution have become serious issues of sustainable development. e Energy Development Corporation envisions the world powered by clean energy and calls on the energy sector to make the necessary shift to clean and low-carbon energy to alleviate the energy issues [1]. With the development of the world economy and the depletion of natural resources, energy crisis and environmental pollution have become serious issues of sustainable development. Demand-side management as an important part of the smart grid is a critical way and an inevitable choice to achieve energy-saving and sustainable development of power enterprises. In order to meet various requests of the power users, the smart grid needs to continuously deepen the power demand-side response and guidance mechanism to enhance the energy-saving and environmental protection effects [3]. E smart grid needs to propose a series of incentive mechanisms and effective demand response strategies to increase the flexibility of demand-side management to improve its sustainability. Smart grid programs should be carefully designed and can integrate the use of renewable energy, reduce electricity use, and lower CO2 emissions. Some research studies have turned to focus on the design of a new hybrid smart grid performance framework for evaluation from the perspective of sustainability [4]
