Smart Meter Based Non-intrusive Load Disaggregation and Load Monitoring

Abstract

AbstractWith the advancement in metering technology, a large field of possibilities has opened. The presence of smart meters that from year to year have better metering capabilities is rising, and they are common for both commercial and residential consumers. By using these single-point measurements of current and voltage with the appropriate load disaggregation techniques, a feasible solution that separates and classifies the loads at that metering point could be achieved. On the other hand, the increasing interest in load management and energy efficiency drives the need for non-intrusive load monitoring (NILM) techniques with a minimum invasion of privacy. The research presents the NILM technique based on the smart meter voltage and current measurements. The developed algorithm in MATLAB simulation software is tested with the laboratory test case with the smart meter measurements and four different appliances, and the results demonstrate the satisfactory accuracy and applicability of the technique. This research is contributing to the existing body of knowledge in terms of developing and testing the non-intrusive load monitoring technique that is seen as a natural upgrade to the existing smart meter functionalities.KeywordsMonitoringLoadSmart meteringSignal processingEnergy managementEnergy efficiency
