Base station energy storage ESS communication signal

To describe the access mechanism between the EMCs and the BSs, we introduce an N b s × N m g connection matrix A, where N m g is the EMCs number and N b s is the number of power towers which is also the number of candidate locations for base stations. It is not necessary for all power towers to be selected as communication power sharing towers.

As shown in Figure S3 each user accesses a base station, and the BS then allocates a channel to each new user when there is remaining channel capacity. If all of the channel capacity of a BS is occupied, a user cannot access this BS and must instead access another BS that is farther away.

The MG is managed by an energy management controllers (EMCs) that coordinates the dispatch of energy in the MG by interacting with information from other EMCs. This information can be interacted with through a communication network. Therefore, BSs are the main intermediaries between communication and energy systems.

The investment costs for an ESS with a 20 MWh capacity and an equivalent 5G communication BS for an MG were taken to be $ 1 × 10 6 and $ 6 × 10 6, respectively, and the investment cost for a 1-MW solar panel was taken to be $ 2.4 × 10 5.

For the communication network, a BS is an important transfer point for wireless information transmission. For the distribution network, it is the main communication device and consumes electricity. The communications operator is responsible for the construction of BSs.

Secondly, this study lacks of exploration regarding the heterogeneous BS channel allocation strategies for different users. In practice, users within a communication network often exhibit diverse requirements and characteristics, and their BS channel allocation needs may vary accordingly.
