Research on the operating mode of the power supply for a telecom base station based on the peak & valley model of the power grid

Abstract

With the development of mobile communication technology, communication system requires significantly more electricity, according to statistics, in the year 2015 a company mobile base station's power charge reached ¥750 million Yuan. Considering the implementation of the peak and valley price mechanism in some areas, and how battery technology has developed, this paper presents the peak and valley operating mode of a communication base station power supply system, and analyzes and evaluates the operation benefit. The controller of base station power can set the peak and valley time freely according to the peak and valley price model and the battery capacity, and support single peak operation and multi-peak operating mode. The Battery's power is used as much as possible during peak period, battery power is used preferentially during the flat hump period, and the power grid charges the battery and power communication base station in the valley period. This can greatly reduce the peak period electricity consumption, is conducive to lower operating costs and stable operation of the power grid. With the application of a hybrid energy system in a communication base station, the hybrid power supply system is introduced to reduce the demand for battery capacity and reduce the grid's power consumption. The research shows that the operating mode based on the grid peak and valley model can greatly reduce operating costs, and because of the introduction of solar energy, it achieves an energy-saving emission reduction, and also helps to further expand economic benefits.
