A Prototypal Architecture of a IEEE 21451 Network for Smart Grid Applications Based on Power Line Communications

This paper deals with the development of reliable measurement and communication devices and systems and their integration on a prototypal network architecture for smart grid applications, based on the use of narrowband power line communications (PLCs). The proposed solution is presented and discussed in the framework of the ISO/IEC/IEEE 21451 family of Standards. Currently, PLCs are not properly addressed by the aforesaid Standards; on the other hand, by including such issue, their guidelines could represent a common platform for the integration and interoperability of the proposed systems and devices. This would allow to exploit the benefits of the IEEE 21451 approach also for PLC-based smart grid applications, not only for the known functions of the smart metering, but also for sensing, automation, protection, and control functions and advanced system operation and management.
