Problems solved by technology

The 5G communication frequency band is relatively high, and under the same power, the transmission distance decreases, and the coverage of a single 5G base station is smaller than that of a 4G base station
When the power system supplies power normally, the battery energy storage inside the communication base station has been idle, resulting in a waste of resources

Embodiment Construction

[0071] The present invention provides a 5G base station energy storage control method that takes into account the communication load status of the base station. The present invention will be described below with reference to the accompanying drawings.

[0072] Step 1, base station energy storage group discrimination

[0073] First of all, it is necessary to determine which base station energy storage can be controlled and which cannot be controlled, and which energy storage is suitable for charging and which energy storage is suitable for discharging; currently, four indicators for the grouping of 5G base station energy storage are selected, which are:

[0074] 1) Mains power supply status: It is the first state quantity to be considered. The regulation of 5G base station energy storage that we have studied is based on the condition that the energy storage is idle. The original intention of backup power.

[0075] 2) Base station load status: Different base stations have diffe...

Abstract

The invention discloses a 5G base station energy storage regulation and control method considering a base station communication load state, and belongs to the technical field of energy storage charge and discharge control. The method comprises the steps of firstly, analyzing the energy storage and communication load state of the 5G base station, and determining whether the energy storage of the base station can be regulated or not according to the mains supply state, the load state of the base station and the energy storage charge-discharge frequency state; then determining the dispatchable capacity which can be provided for the power grid by base station energy storage participating in power grid collaborative interaction according to the communication load capacity of the base station; and finally, establishing a 5G base station energy storage participation power grid peak clipping and valley filling model by using the variance of the minimum load curve as an optimization objective function,formulating a 5G base station energy storage regulation and control strategy according to an optimization result, and controlling the base station energy storage to participate in power grid coordination and interaction. The method can stabilize the power fluctuation of the power grid, reduce the peak-valley difference and delay the upgrading of power grid facilities; and the base station energy storage participates in peak clipping and valley filling of the power grid, and the power utilization cost of an operator can be reduced by utilizing peak-valley arbitrage, so that the mutual benefit and win-win situation of the power grid and the communication operator is achieved on the premise of not influencing the communication service quality of the base station and the 5G user experience.

Description

technical field [0001] The invention belongs to the technical field of energy storage charge and discharge control, and in particular relates to a 5G base station energy storage control method that takes into account the communication load status of the base station. Background technique [0002] In the past two years, my country has clearly proposed on many occasions to speed up the development of "new infrastructure". As a representative of new infrastructure, 5G base station construction is steadily advancing the construction process. The 5G communication frequency band is relatively high, and under the same power, the transmission distance is reduced, and the coverage of a single 5G base station is smaller than that of a 4G base station. At the same time, since 5G uses a larger array antenna and higher bandwidth, the energy consumption of the base station is significantly higher than that of the original 3G and 4G base stations. In the 5G era, due to the sharp increase ...
