6 Frequently Asked Questions about “Base station wind power supply sleep”
Can a 5G base station energy storage sleep mechanism be optimized?
The optimization configuration method for the 5G base station energy storage proposed in this article, that considered the sleep mechanism, has certain engineering application prospects and practical value; however, the factors considered are not comprehensive enough.
What is the sleep mechanism of a base station?
The sleep mechanism of a base station refers to the intelligent shutdown of major power consumption devices, such as the AAU of the base station, when there is no load or the load is low, such that the energy consumption is greatly reduced.
Does a 5G base station use energy storage power supply?
In this article, we assumed that the 5G base station adopted the mode of combining grid power supply with energy storage power supply.
How to optimize energy storage planning and operation in 5G base stations?
In the optimal configuration of energy storage in 5G base stations, long-term planning and short-term operation of the energy storage are interconnected. Therefore, a two-layer optimization model was established to optimize the comprehensive benefits of energy storage planning and operation.
Can a bi-level optimization model maximize the benefits of base station energy storage?
To maximize overall benefits for the investors and operators of base station energy storage, we proposed a bi-level optimization model for the operation of the energy storage, and the planning of 5G base stations considering the sleep mechanism.
Can BS sleep save power?
Both of the BS sleeping mechanisms verify that the potential of power saving is significant, especially when the load is relatively low (e.g., 1:00-7:00). Compared with no traffic prediction and BS sleeping, about 40:2% and 30:8% power consumption can be saved on average by our scheme and greedy-based scheme, respectively.
