Intelligent energy efficient street lighting system with predictive energy consumption

Abstract

This paper considers an autonomous intelligent street lighting system with energy efficient predictive algorithm. The work is related to control of the system which uses algorithms that could provide with energy each lamppost during the night time. To this end, lamp posts are equipped with batteries, motion and light sensors and uniaxial solar trackers with azimuth orientation to the Sun. To simplify system monitoring, several lampposts are grouped together and controlled by a single control unit. The control unit is equipped with XBee 3 wireless module. Based on weather forecast for the coming days, the system adapts to weather condition changes and makes calculations of consumption and operating time. These calculations allow us to distribute the system energy consumption evenly during these days.
