Abstract: Cellular base stations (BSs) are equipped with backup batteries to obtain the uninterruptible power supply (UPS) and maintain the power supply reliability. While maintaining the reliability, the backup batteries of 5G BSs have some spare capacity over time due to the traffic-sensitive characteristic of 5G BS electricity load.
In practice, the battery groups (either traditional lead-acid batteries or emerging lithium ones) are deployed as the backup power supply of BSs. In our scenario, one battery group could be shared by multiple BSs nearby to exploit the statistical multiplexing gain, and the multiple BSs sharing the same battery group form a virtual cell (VC).
Therefore, the spare capacity is dispatchable and can be used as flexibility resources for power systems. This paper evaluates the dispatchable capacity of the BS backup batteries in distribution networks and illustrates how it can be utilized in power systems.
These power demands, from one side, are satisfied by the power grid, and are safeguarded by backup batteries from the other side. As the power from the grid does not necessarily guarantee 100% uptime, the backup power provided by batteries is playing an important role.
This paper evaluates the dispatchable capacity of the BS backup batteries in distribution networks and illustrates how it can be utilized in power systems. The BS reliability model is first established considering potential distribution network interruptions and the effects of backup batteries.
Therefore, BS power backup is in great need to keep the reliability of future mobile networks, especially for the macro BSs with large areas of network coverage and small ones serving mission-critical mobile and edge services (e.g., connected and automated vehicles ).
