Peak-load period refrigerator control for end-consumer load management

In smart-grid area, the devices for end-consumers are one of the most important items. This paper presents a device developed to be installed in conventional refrigerators and freezers (white-line apparatus). Its main idea is change the daily load profile, moving the load from the peak-load period to a period before the peak-load. The proposed device inputs collect automatically consumer habits and apparatus features, such as: frequency and time of door opening of white-line apparatus during the peak-load period, the internal temperature, the equipment thermo-dynamic features, among others. And then, after an information computational process, the device provide the command on/off for the white-line apparatus compressor. Finally, this paper presents some practical results in real-life apparatus.
