Analysis of data transmission based on the priority over grid structures

Due to the rapid development of smart grid, the quality of service for bidirection communication becomes very important to improve the performance of smart grid. Especially, to take the challenge of future trend and demand, how to deal with the big data within smart grid must be resolved. In this paper, we make an analysis of data transmission over the new network architecture for smart grid. Our analysis is based on a theoretical model designed for the data transmission, where different data has different priority for different situations according to the network and grid structure. We carry out the simulation and show the relationship and properties for different possible methods to transmit data with priorities. Results show that the transmission cost can be reduced with the priorities based method.
