Smart Meter Reading System Based on Cognitive Technology
Dongjing Hu, Yunxiao Zu, Bin Hou · 2013
Smart grid system is an automated power system that monitors and controls grid activities.Smart grid also makes the power network stable, secure, efficient, flexible, economical, and environmental friendly.However, it has constraints in the dedicated frequency resources and poor performance in electricity allocation and communications.As a new developing communication technology, the cognitive radio suggests a way to reuse the limited spectrum resources due to the shortage and low utilization of frequency bands.A new smart meter reading system based on cognitive technology is designed in this paper.In this grid system, smart meter reading system is replaced by an extended wireless sensor network, in which the cognitive radio technology is a key factor for communication.The simulation results explain that the delay, the accuracy and the bit rate of transmitting can satisfy the communication requirements of the grid.
