Non-intrusive load monitoring

Abstract

Responsible use of energy resources, conserving environment and improving well-being of the society are the major goals towards developing smart sustainable cities, and energy management is the inherent part of the smart sustainable cities programme. Due to high demand of energy in various sectors, energy management has become essential to utilize the available energy efficiently and understand energy usage behavior of the users in order to avoid possible energy wastage. In recent years, non-intrusive load monitoring (NILM) technique has become popular and emerging approach to monitor events and energy consumption of appliances/electrical utilities in buildings using single energy meter. The information about energy consumption at appliance level would help consumers to understand their appliance usage behavior and take necessary steps for reducing energy consumption. The recent advancements in smart metering and internet of things (IoT) have made significant progress in real time implementation of non-intrusive load monitoring (NILM) algorithms in residential and industrial environments.
