Abstract:

A data center represents an important flexible resource on the user side. Through reasonable scheduling and motivating demand response, the capability of the data center to accommodate the power generation from distributed renewable energy sources (RESs) can be effectively improved, which is conducive for achieving the specified “dual carbon” target in China. In this paper, the optimal dispatch and demand response strategies for a data center are addressed to promote the accommodation of the power generation from RESs. Firstly, considering the load characteristics of the data center, a conventional data center operation model including the power demand profile and quality of service (QoS) is established. Then, according to the schedulable characteristics of delay-tolerant workloads, a renewable energy subsidy mechanism is proposed for the data center to motivate the shift of the user data service demand to the peak power generation period of RESs. Then, on the basis of the green certificate (GC) mechanism, with the objective of minimizing the operating cost of the data center and maximizing environmental benefits, an optimal dispatch model of the data center is presented. Finally, a typical data center is employed to demonstrate the feasibility and efficiency of the presented method. Simulation results show that the presented method can effectively explore the demand response potential of the data center and its users, enhance the accommodation capability for power generation from RESs, and hence reduce carbon emission.

Key words: data center, optimal dispatch, demand response, accommodation of renewable energy generation
