Integration of IEC 61850 MMS and IEEE 802.22 for Smart Grid Communication

The reliability of Smart Grid depends on two-way communication between substation and utility. IEC 61850 is an international standard defined to ensure interoperability between Substation Automation System (SAS). IEC 61850 services are mapped on the Manufacturing Message Specification (MMS) especially for meter data management system. MMS is the OSI protocol that run over TCP/ IP or OSI networks to support IEC 61850 services. Presently, the MMS uses Ethernet as the layer 2 protocol. However, for long distance communication in remote areas wireless communication is the prefered mode. The Cognitive Radio based IEEE 802.22 is next generation standard for Wireless Regional Area Network (WRAN) that can support long distance wireless communication for low-latency, high-volume, reliable and secure communication. This paper shows the potential to integrate IEC 61850 MMS with IEEE 802.22 for long distance Smart Grid communication.
