Why do communication base stations use battery energy storage?

Meanwhile, communication base stations often configure battery energy storage as a backup power source to maintain the normal operation of communication equipment [3, 4]. Given the rapid proliferation of 5G base stations in recent years, the significance of communication energy storage has grown exponentially [5, 6].

How do low-load base stations reduce energy consumption?

This strategy flexibly adjusts the user connections of low-load base stations to put inefficient base stations into sleep mode, thereby improving base station utilization and reducing the overall system energy consumption [20, 21].

Can a power grid model reduce the power consumption of base stations?

The analysis results demonstrate that the proposed model can effectively reduce the power consumption of base stations while mitigating the fluctuation of the power grid load.

How can communication energy storage be aggregated?

With regards to the aggregation of communication energy storage, scholars are increasingly and flexibly utilizing dispersed resources through information technology. The literature [7, 8] has constructed a dynamic economic dispatch (DED) combination model that integrates the power system and 5G communication network.

What is a base station energy storage system?

A single base station energy storage system is configured with a set of 48 V/400 A-h energy storage batteries. The initial charge state of the batteries is assumed to obey a normal distribution, assuming that the base station has a uniform specification and its parameters are shown in Table 2. Table 2. Parameters of the energy storage system.

How are communication base stations represented in a given area?

In a given area, the communication base stations are represented as M = {1, 2, , m} base stations, I = {1, 2, , i} mobile users, and T = {1, 2, , t} operating time slots of base stations. Figure 1 illustrates the distribution of communication base stations and users in the region.
