Abstract

This paper proposes a lighting control system based on RTP to save lighting energy cost by utilizing daylight while maintaining target luminance suited to the purpose. DR is a mechanism which transmits load by changing power use pattern depending on the user and receiving power charges signal at real time so that power demand would not exceed supply. However, DR is not actually implemented in an effective way due to a burden on the participants in the program to respond voluntarily towards pricing signals. In this paper, power charge process is categorized into three stages according to power load and proposes an LED control system based on WSN which automatically responds according to power demand. Daylight is controlled with a venetian blind, but it is controlled at the highest angle of uniformity ratio of illumination per time zone to maintain the uniformity of natural lights. This study establishes two test beds having the same environment. Further, illumination cost and power consumption of testing group that provides service with variable target illumination according to RTP as well as control group that serves with fixed target illumination regardless of power consumption were measured and energy saving by both conditions was compared.
