Nonintrusive load detection algorithm based on variations in power consumption

Each electrical appliance has its own pattern of using the electricity. Identifying these patterns can lead to a disaggregation of the entire electricity consumption. This disaggregation, brought to the user, offers a better understanding on how the electricity is consumed inside his home. Also the information obtained from this process brings to the user the power to detect possibilities to reduce its consumption and also its electrical bills, in the context of a world where prices are getting higher each day. This paper presents a new algorithm which detects electrical consumers based on power consumption. The system successfully detects two-state (on-off) and also multi-state devices.
