A method of detecting the manipulation message to provide a reliable Demand Response service

Customers can adjust their own energy usage if the smart grid notifies real-time energy rate which is determined by the current power consumptions. We call these services Demand Response (DR) services. At the Smart Grid environments, consumers can bi-directionally communicate with components of the smart grid through the Advanced Metering Infrastructure (AMI). So the smart gird can provide Demand Response services for reducing energy usage during hours of peak demand. However Demand Response services can be misused if messages between customers and the smart grid are modified by attackers. In this paper, we propose a method to detect the manipulation of message, while the meter reading value is being transferred from Smart Meter to Meter Data Management System (MDMS) through the AMI. It is expected to provide a reliable Demand Response service, and lead to more efficient power usage, through the detecting scheme of this paper.
