Analysis on Invulnerability and Real-Time Performance for Smart Grid Network

In the process of building strong smart grid, the communication technology becomes an important means that supports Intelligrid Architecture. Smart grid has strict requirements in the reliability and real-time performance of communication. MPLS can improve the service quality of power communication. Aiming at the MPLS area, this paper proposes a kind of artificial spider web topology and analyses the invulnerability. Based on this, the OPNET simulation is run for road-balancing and re-routing. The results show that the MPLS routing algorithm has strong ability of road-balancing and re-routing. It can be used to improve the real-time performance of communication.
