Real-time Disaggregation of Residential Energy Consumption Enhanced with User Feedback

Abstract

Non-Intrusive Appliance Load Monitoring (NIALM) is a process for deducting what appliances are being used in a household by observing the total energy consumption over time. Such process makes it possible to provide energy management services to a large number of users without installation of per-appliance meters. This paper analyzes the performance of NIALM when used to provide real-time services. In addition, the paper studies how the performance of NIALM could be improved by dynamically selecting the disaggregation model on the basis of user feedback about the correctness of the disaggregation.
