Therefore, considering the configuration of renewable energy, the adjustability of energy storage battery, and the space-time characteristics of communication load, this study proposes a hierarchical distributed operational framework for renewables-assisted 5G base. Therefore, considering the configuration of renewable energy, the adjustability of energy storage battery, and the space-time characteristics of communication load, this study proposes a hierarchical distributed operational framework for renewables-assisted 5G base. 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. Then, the PV and ESS capacity optimization for. With its technical advantages of high speed, low latency, and broad connectivity, fifth-generation mobile communication technology has brought about unprecedented development in numerous vertical application scenarios. However, the high energy consumption and expansion difficulties of 5G. The power consumption of a 5G base station (BS) at full load is close to 4 kW, about three times that of a 4G BS ( ), which increases the pressure on electricity expenditure faced by communication operators. 6GHz, and the frequencies of 5G high-frequency base stations are above 28GHz.
