What is a 5G base station?
At the same time, a large number of 5G base stations (BSs) are connected to distribution networks , which usually involve high power consumption and are equipped with backup energy storage , , giving it significant demand response potential.
What are the parameters of BS Energy Storage?
The channel bandwidth B allocated by the user is 1 MHz, the upper limit of the BS's traffic processing capacity L max is 10 4 Mbps, and the traffic demand L j of a single user is 100 Mbps. The detailed parameters of the BS energy storage are shown in Table 1. ω is taken as small as 0.14 Yuan/kWh to encourage energy storage participation.
What is a collaborative optimal operation model of 5G base stations?
Afterward, a collaborative optimal operation model of power distribution and communication networks is designed to fully explore the operation flexibility of 5G base stations, and then an improved distributed algorithm based on the ADMM is developed to achieve the collaborative optimization equilibrium.
Can a 5G base station enter a hibernation state?
If the communication load can only connect to one 5G BS, the base station cannot enter a hibernation state by load migration. In addition, the capacity of 5G BS to carry the communication load has an upper limit, dependent on the transmission traffic constraints and transmission power constraints, as shown in Equations (10), (11).
What is 5G BS energy storage capacity?
Energy storage, as a backup energy source for 5G BS, is needed to supply power to the BS in case of distribution network failure. As shown in Fig. 3, the 5G BS energy storage capacity can be divided into backup capacity and dispatchable capacity .
