Review of energy management for data centers in energy internet

Data centers play an important role in the big data era. With the continuous expansion of data centers, the problem of their huge energy consumption has attracted a lot of attention and thus the energy management has become a major focus for data center industry. In the energy internet environment, data centers are expected to have more diversified choices to gain energy supply, discover more flexible and efficient energy management methods, and their energy management modes that only rely on electricity could be reformed fundamentally. From a new perspective of energy internet, the research and practice related to the energy management for data centers are reviewed. Firstly, the service structure and the infrastructure of data centers are discussed. Then, the energy consumption structure, energy efficiency and energy consumption model of data centers are provided. Afterwards, the energy management methods of data centers in the context of energy internet are analyzed in detail. At last, the challenges and difficulties of energy management for data centers in the context of energy internet in the future are discussed.
