Description

technical field [0001] The present invention relates to the technical field of optical storage system capacity optimization, in particular to an energy sharing-based 5G base station micro-grid optical storage system capacity optimization configuration method. Background technique [0002] In recent years, investment in new information infrastructure represented by 5G has increased. It is estimated that by 2025, the electricity consumption of 5G base stations will reach about 350 billion kWh. At present, reducing equipment energy consumption and electricity bills is a major demand for 5G commercial use. In order to ensure the stable use of 5G base stations, operators generally configure backup power supplies for macro base stations according to the maximum energy demand, and micro base stations with backup power supplies account for 70%. With the strong construction of the power grid and the continuous improvement of power supply reliability, the utilization rate of backup e...

Problems solved by technology

[0003] The existing micro-grid optical-storage system capacity optimization configuration method aims to minimize the configured photovoltaic and energy storage capacity, formulate an optical-storage micro-grid economic dispatch or optimize the operation plan, and lacks the communication characteristics of the 5G base station and the backup power guarantee base station Considering the demand for reliable power consumption, it is impossible to ensure that the 5G base station can reduce energy consumption under the premise of meeting the needs of users, and it is not suitable for the research on the optimal configuration of the optical storage capacity of the 5G base station micro-network.

Most of the existing research on energy saving and consumption reduction of 5G base stations focuses on the base station's own energy saving technology and interaction with renewable energy, and does not include its own backup battery in the scope of research.
