International Journal "Information Models and Analyses" Volume 7, Number 2, © 2018 114 A STUDY ON PATTERN DISCOVERY OF SMART METER DATA FOR ENERGY EFFICIENCY Sarah Osama, Marco Alfonse, Abdel-Badeeh M. Salem Abstract: Infinite massive amount of data are being generated from smart meters. Precious information can be obtained by analyzing these data for efficient use of energy. Data mining algorithms are extensively used for extracting these valuable information. Researchers have been focusing on developing energy management solutions for a cleaner environment. Recognizing residents behavior and provisioning a feedback continuously about their usage is one of the effective ways to save energy in residential sector. It is assumed that the more they know and understand their consumption, the more they can track their behavior and save energy. This paper presents a study on the recent research covered for understanding behavior of household energy consumption using pattern mining algorithms as well as applications developed for reducing energy consumption and achieving a much better and efficient use of energy. The pattern discovery techniques applied during the recent 5 years are also presented. Keywords: Smart Grid, Smart Meters, Pattern Mining, Smart Home, Energy Management.

According to the US energy information administration annual report for 2017, residential and commercial sectors are contributing by 40% of the total power in US [EIA, Online]. Mining consumption data at increased level of granularity has attracted the keen interest of industrial and governmental sectors. Governments such as Australia, Canada, Europe, Korea, Ireland, Japan, UK and USA are investing in smart meters deployment although it is very costly and requires huge IT and communication infrastructure [Smart Grid, Online]. Smart meters are considered as a key component for initializing smart grid environment. Smart grid [Hassan, Radman, 2010] is a network of utilities, smart meters, transmission lines and power plants integrated together. The grid is called smart for being able to communicate in bidirectional way and making real time decisions. The current power electric grid is facing a lot of challenges and the smart grid, considered as its next generation, has emerged for tackling these challenges such as system stress and blackouts [Fang et al, 2012].
