Low Cost Smart Power Metering

"Modern trends, including increased electricity. requirements and improvements in grid management. technologies, are causing the electric industry and regulators to. review how the grid is achieved. With this aim, in this paper a. low cost solution for the real-time energy management in a smart. grid, is presented. It provides several smart meters, which act as. slaves, that continuously monitor connected loads communicating. with a data aggregator via CAN bus. Through the implemented. web server the users can remotely control their consumption. using a web browser. To prevent external attacks, a low. computational cost protection software, based on Message. Authentication Code (MAC), has been implemented. The paper. illustrates the hardware architecture, discusses the adopted. software solutions, and is completed with an example of energy. monitoring for a generic household thanks the web server."
