Given the backup power sharing scenario in Sect. 4.3.3 and illustrated by Fig. 4.4, two types of power outages may happen. To keep the network reliability, we need to control the possibility of network failures caused by asynchronous outages under a predefined threshold (denoted by đťś–). Further practical constraints during the backup power deployment are as follows. 1. No BS misses: for any BS, its backup power is supplied by the batteries at one. Note that among the above mathematical representations, only x and yare unknown variables that need to solve, and all the other nations are either prior.
Base stations' backup energy storage time is often related to the reliability of power supply between power grids. For areas with high power supply reliability, the backup energy storage time of base stations can be set smaller.
For the determination of the backup energy storage capacity of base stations in different regions, this paper mainly considers three factors: power supply reliability of the grid node where the base station is located (grid node vulnerability), the load level of the grid node and communication load.
According to the inverse relationship between the power supply reliability of the distribution network and the backup time of the base station, the traditional base station energy storage model is modified to obtain a base station energy storage model that is affected by power supply reliability and base station communication volume.
Based on the established energy storage capacity model, this paper establishes a strategy for using base station energy storage to participate in emergency power supply in distribution network fault areas.
The case analysis done in this article verifies the effectiveness of the proposed method: places with high power supply reliability have more available base station energy storage capacity. Where traffic is high, less base station energy storage capacity is available.
For the backup capacity of base stations under fixed backup time, this article assumes that the backup time of base stations at each node of the power grid is 3 h, and other parameters remain unchanged. The backup capacity results of each power grid node under the fixed backup time of the base station are shown in Fig. 23. Fig. 23.

Telecommunications facilities typically have at least an eight-hour backup, often required by regulations. However, in areas prone to extended power outages, like those at risk during hurricanes, a backup capability of 24 to 72 hours is needed. To meet these requirements, providers use a mix of these three backup power technologies;
Cell towers rely on backup power systems like batteries and generators to stay operational during power outages or grid failures. Therefore, telecom providers depend on backup power to ensure a constant power supply. The backup power for cell towers becomes crucial to notify responders and call centers during crises, ultimately saving lives.
Among various battery technologies, Lithium Iron Phosphate (LiFePO4) batteries stand out as the ideal choice for telecom base station backup power due to their high safety, long lifespan, and excellent thermal stability.

However, there are few studies on the feasibility of 5G base station energy storage participating in the emergency restoration of the power grid.
The denseness and dispersion of 5G base stations make the distance between base station energy storage and power users closer. When the user's load loses power, the relevant energy storage can be quickly controlled to participate in the power supply of the lost load.
The power consumption of a single 5G station is 2.5 to 3.5 times higher than that of a single 4G station. The main factor behind this increase in 5G power consumption is the high power usage of the active antenna unit (AAU). Under a full workload, a single station uses nearly 3700W.

Model of Base Station Power System The key equipment in 5G base stations are the baseband unit (BBU) and active antenna unit (AAU), both of which are direct current loads. The power of AAU contributes to roughly 80% of the overall communication system power and is highly dependent on the communication volume .

Aiming at minimizing the base station (BS) energy consumption under low and medium load scenarios, the 3GPP recently completed a Release 18 study on energy saving techniques for 5G NR BSs . A broad range of techniques was evaluated in terms of the obtained network energy saving (NES) gain and their impact to the user-perceived throughput (UPT).
The denseness and dispersion of 5G base stations make the distance between base station energy storage and power users closer. When the user's load loses power, the relevant energy storage can be quickly controlled to participate in the power supply of the lost load.
Where traffic is high, less base station energy storage capacity is available. Compared with the fixed backup time, the base station energy storage model proposed in this article not only improves the utilization rate of base station energy storage, but also reduces the power loss load and power loss cost in the distribution network fault area.
the power consumption of AAU nearly linearly increases with the growth of BS load rate, while that of the BBU is quite stable at varying load rates. As the power consumption of 5G BSs is significantly higher than that of 4G BSs, we focus on the backup power allocation of 5G networks in this work.
