Review of Techniques for Non-Intrusive Electrical Load Monitoring

August 13, 2010 - 12:00pm
Seminar Host/Point of Contact: 

Non-intrusive load monitoring (NILM) is a method to estimate the energy and power use of individual electrical devices in buildings. It generally relies on aggregate power metering (at the whole-building or branch circuit level) and special signal processing techniques to disaggregate the total power consumption data into loads from individual appliances, thus avoiding the time and expense of placing power meters on each device. Over the last 30 years, a variety of NILM techniques have been developed, which differ in the types of data collected, the sampling frequency, the types of metering hardware required, and the signal processing algorithms employed. Dr. Roth will summarize the principal NILM techniques that have been described in the literature, and discuss the pros and cons of the various approaches for accurately collecting data in real buildings. He will also present a brief summary of research work being performed at the Fraunhofer CSE. A recording of this seminar is available at
