Smart meter-based home energy report: Design and operation of automatic generation system of hourly usage indication message

Abstract

Home Energy Report (HER) is gathering attention as a method to promote energy conservation behavior in residential sector. Most of the existing efforts about HER assume the use of total monthly usage data. These usually compare customers’ monthly usages with that of similar neighbors. In our study, we developed a HER that uses smart meter data to give graphical information on customers’ monthly, weekly, daily and hourly electricity usages. In the smart meter-based HER, the graphs that show hourly usage patterns are applied the method of automatically generating a message commenting the time zone to be paid attention by each customer. The automatic generation method uses smart meter data and several types of baseline hourly usages to analyze which time zone each customer should pay attention. In this paper, we provide a detailed explanation about the structure of the automatic generation method, and show analysis results of how the method have been worked by using the HER generation log data of approximately forty thousand households for twelve months.
