Optimal capacity planning and operation of shared energy
A dynamic capacity leasing model of shared energy storage system is proposed with consideration of the power supply and load demand characteristics of large-scale 5G
Setting up a 5G base station is expensive, with costs ranging from $100,000 to $200,000 per site. This price includes hardware, installation, site rental, and maintenance. Urban areas often have higher costs due to land prices and infrastructure challenges.
Model of Base Station Power System The key equipment in 5G base stations are the baseband unit (BBU) and active antenna unit (AAU), both of which are direct current loads. The power of AAU contributes to roughly 80% of the overall communication system power and is highly dependent on the communication volume .

The annual operation cost of large-scale 5G BSs in Case 1 is the highest, while that in Case 3 is the lowest. The annual electricity buying cost of large-scale 5G BSs in Case 1 is 4339.20 (10 3 CNY), accounting for 96.60% of operation cost. Compared with Case 1, the annual operation cost of 5G BSs in Case 2 is reduced by 11.55%.
