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 𝜖). 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.
[PDF Version]The backup battery of a 5G base station must ensure continuous power supply to it, in the case of a power failure. As the number of 5G base stations, and their power consumption increase significantly compared with that of 4G base stations, the demand for backup batteries increases simultaneously.
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 massive growth of 5G base stations in the current power grid will not only increase power consumption, but also bring considerable energy storage resources. However, there are few studies on the feasibility of 5G base station energy storage participating in the emergency restoration of the power grid.
In this article, we assumed that the 5G base station adopted the mode of combining grid power supply with energy storage power supply.
