Introduction In China, the power consumption of power grid enterprises data centers is increasing. To calculate the whole energy effectiveness condition of the data centers, this paper proposes a feasible power grid enterprise data center energy effectiveness measurement standard and calculation method.
Method By studying the data center energy effectiveness evaluation methods both in China and abroad, in view of the features which power grid enterprises data centers may share some of the infrastructure with their office buildings, we proposed three kinds of optimization methods, including accurate calculation of IT load, optimized estimation of power consumption of power distribution unit in the cabinet, optimized estimation of power consumption of the cooling water system, and the optimized energy effectiveness measurement and calculation method.
Results The results show that: by using this method, energy consumption in non-data center regions can be separated in calculation, which is more accurate than the conventional calculation method, closer to the international general data center power effectiveness definition, and can truly reflect the power effectiveness level of power grid enterprise data center.
Conclusion The proposed method is simple and effective, which can provide the basis for comparing energy effectiveness with different data centers and energy saving level assessment.
