The paper aims to provide an outline of energy-efficient solutions for base stations of wireless cellular networks. . With the rapid development of 5G base station construction, significant energy storage is installed to ensure stable communication. To enhance the utilization of base station energy storage (BSES), this paper proposes a. . Therefore, aiming to optimize the energy utilization efficiency of 5G base stations, a novel distributed photovoltaic 5G base station DC microgrid structure and an energy management strategy based on the Curve Fitting–Perturb and Observe–Incremental Conductance (CF-P&O-INC) Maximum Power Point. . In today's 5G era, the energy efficiency (EE) of cellular base stations is crucial for sustainable communication. The measured results showed that the system ran stably, the temperature inside the cabinet was controlled between 12 °C and 39 °C with no high temperature alarm, the compressor running time was significantly reduced, the. .
