An improved base station power system model is proposed in this paper, which takes into consideration the behavior of converters. And through this, a multi-faceted assessment criterion that considers both economic and ecological factors is established.
An improved base station power system model is established in this paper. The model not only contains the cost and carbon emissions of the converters, PV, and ESS, but also contains the relationship between the converter efficiency and its operating conditions.
Abstract: Cellular base stations (BSs) are equipped with backup batteries to obtain the uninterruptible power supply (UPS) and maintain the power supply reliability. While maintaining the reliability, the backup batteries of 5G BSs have some spare capacity over time due to the traffic-sensitive characteristic of 5G BS electricity load.
The influence of converter behavior in base station power supply systems is considered from economic and ecological perspectives in this paper, and an optimal capacity planning of PV and ESS is established. Comparative analyses were conducted for three different PV access schemes and two different climate conditions.
The main conclusions are as follows: The loss of power converters significantly affects the optimization of base station PV and ESS. Calculating with a fixed efficiency cannot accurately reflect the actual situation. The proposed evaluation method achieves a balance in LCC, initial investment, return on investment, and carbon emissions.
