This paper proposes a distribution network fault emergency power supply recovery strategy based on 5G base station energy storage. This strategy introduces Theil's entropy and modified Gini coef.
Why do base stations have a small backup energy storage time?
Base stations' backup energy storage time is often related to the reliability of power supply between power grids. For areas with high power supply reliability, the backup energy storage time of base stations can be set smaller.
Can base station energy storage participate in emergency power supply?
Based on the established energy storage capacity model, this paper establishes a strategy for using base station energy storage to participate in emergency power supply in distribution network fault areas.
How to determine backup energy storage capacity of base stations?
For the determination of the backup energy storage capacity of base stations in different regions, this paper mainly considers three factors: power supply reliability of the grid node where the base station is located (grid node vulnerability), the load level of the grid node and communication load.
Based on the base station energy storage capacity model established in contribution (1), an objective function is established to minimize the system operating cost in the fault area, and the base station energy storage owned by mobile operators is used as an emergency power source to participate in power supply restoration.
Does a high power supply reliability increase base station energy storage capacity?
The case analysis done in this article verifies the effectiveness of the proposed method: places with high power supply reliability have more available base station energy storage capacity. Where traffic is high, less base station energy storage capacity is available.
Do mobile operators support the use of base station energy storage?
The premise of the research conducted in this article is that mobile operators support the use of base station energy storage to participate in emergency power supply.
