Peak-cut control of smart energy BTS: Power control technology for reducing the power consumed by base stations

Abstract

Reducing the power consumed by base stations is an urgent requirement. Our research shows that it is possible to reduce electricity consumption, especially peak loads, by predicting the power demands of base stations. This approach is implemented in the Green Power Controller, a technique developed for the Green Base Station which is the power system of base stations used for disaster relief and reducing energy costs. Trials of an implemented controller confirm that the control proposal is effective in reducing electricity consumption by suppressing the peaks in electric power consumption. In anticipation of electricity-network liberalization and accompanying power reforms, we will consider the role of the Green Power Controller and develop even more effective electricity rate reduction measures.
