Application of Virtual Local Area Network Technology in Smart Grid

The management of the smart grid operation process requires massive data. How to quickly, reliably transmit, process, and store these data becomes a necessary topic for effective management of the smart grid. This article mainly studies the application of virtual local area network technology in smart grid. Based on the analysis of the basic characteristics of smart grid management, this paper designs a three-layer switched virtual local area network (VLAN), which effectively divides the distributed smart grid data management system into subsystems that are not restricted by geographical locations and have clear logical communication units. In the experiments of this paper, because the client and server in the service-based VLAN are usually in the same VLAN, only about 10% of the communications that randomly occur between the VLANs need to be routed, which is basically stable at 0% to 4%. between. The VLAN based on the traditional policy decreases the routing amount as the maximum number of hosts in the same VLAN increases. It can be seen that the system in this paper can effectively reduce network congestion and improve the efficiency of smart grid data processing.
