Quality Control and Communication in Smart Grid Using IED & PLCC

Abstract

In the era of growing power demand and power networks, continuous supply of power and data exchanges is inevitable nurturing the implementation of smart grid technology. The smart grid is a self-healing technology which promises the electricity consumers to be an active participant. However, Intelligent Electronic Device (IED) supports the SG as the backbone for operation imparting the functionalities such as protection and monitoring the power networks. But the limitations of the common IED are its finite allocation of functions without modifying its hardware. Moreover, these IEDs confront the communication problems during natural calamities and other network failures as it adopts the cellular communication topology. The limitations mentioned above can be overcome by adopting the flexible IEDs integrated with signal conditioning, filtering and discretization functions along with the implementation of Power Line Carrier communication. The flexible IED and the PLCC extends the scalability of the most reliable and highly efficient smart grid architecture.
