A data-based approach for online smart meter calibration

Abstract

The smart meter has been considered the key element in the smart grid. The current smart meter verification method mainly focuses on on-site and laboratory detection and fails to test all deployed meters. Online calibration is a novel approach that calculates meter error by analyzing meter reading data. By presenting a comprehensive survey and basic model of online smart meter calibration, this study proposes a recursive algorithm in order to estimate meter error. Concrete steps are subsequently illustrated. The following testing case shows the higher accuracy of the method. Finally, some issues related to the application of online calibration are discussed.
