Data center peak-shifting energy storage

Can energy storage devices reshape the power demand curve of a data center?

Abstract: Recent studies have proposed to dynamically reshape the power demand curve of a data center (i.e., power shaving) with energy storage devices, particularly uninterruptible power supply (UPS) batteries.

Do data centers shave peak power demand?

This paper proposes efficient strategies that shave Data Centers (DCs)' monthly peak power demand with the aim of reducing the DCs' monthly expenses. Specifical

Can thermal energy storage shave peak demands?

In order to shave the peak demands, Zheng et al. considered using Thermal Energy Storage (TES) tanks to make iced water during low electricity price periods so that it can be used later to reduce the power spent by the cooling infrastructure during peak power demand periods.

Why do data centers use power shaving?

Power shaving can be used to limit the peak power demand in a data center, in order to reduce both the power infrastructure investment (i.e., cap-ex) and the electricity bills (i.e., op-ex). However, power shaving requires the UPS batteries to be frequently charged/discharged, which is known to compromise the battery lifetime and availability.

Does storage capacity affect the cost of data center?

The results showed that storage capacity and the location of data center affected the cost of storage devices and the energy supply, and energy storage didn’t always turn to reduce comprehensive operation cost of data center.

Does thermal time shifting reduce data center cooling costs?

Thermal time shifting: decreasing data center cooling costs with phase-change materials Investigation of PCM-assisted heat pipe for electronic cooling 10th International Conference on Thermal Energy Storage ( 2006) Thermal performance of LHSU for electronics under steady and transient operations modes
