Abstract: In order to achieve accurate estimation, and fully consider the user location information, a low power strategy of a wireless network based on a grid-connected solar photovoltaic/cell system is proposed. First, in order to ensure the continuity of power supply, a grid-connected solar photovoltaic/cell system is established. Then, considering the intermittent behavior of solar intensity and traffic volume, the influence of base station transmitted power and system bandwidth on system performance is analyzed, and the throughput, energy efficiency and spectrum efficiency of the wireless network are evaluated. A heuristic load balancing algorithm and resource block allocation technology are proposed to maximize the efficiency and energy efficiency of the system by optimizing the use of green energy.Numerical results show that the proposed grid-connected solar photovoltaic/cell system can significantly reduce power grid energy consumption, the power generation efficiency is up to 54.8%, and significant energy sustainability is ensured through an effective renewable energy collection model.
