In recent years, with the proposal of strong and smart grid, the reliability requirements of the Electric Power Data Network are getting higher and higher. Based on the background, this paper proposes a novel Electric Power Data Network for the smart grid. After that a comparative analysis on the information congestion degree is provided between the novel Electric Power Data Network based on artificial spider web topology and the traditional Electric Power Data Network based on the star topology. The results show that the Electric Power Data Network using the artificial spider web topology has a higher reliability.
