Why are power systems and communication systems increasingly coupled?

Therefore, power systems and communication systems are increasingly coupled. A power system supplies energy, and a communication system meets the demand for information exchange. A BS is the main intermediary between a communication network and a power network.

How does a base station work?

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.

What is the access mechanism between EMCs and BSS?

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.

What is a BS in energy management?

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.

Does the power consumption of a BS increase linearly?

The power consumption of BS n increases linearly with its total transmit power, including all subcarriers. Intuitively, the power load of a BS has a linear relationship with its communication load. In this paper, the BS access scheme is modelled via OFDMA. Note that the use of OFDMA is convenient for performance evaluation.

Do heterogeneous BS channel allocation strategies exist for different users?

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.
