The advent of power line communication (PLC) for smart grids, vehicular communications, internet of things and data network access has recently gained ample interest in industry and academia. Due to the characteristics of electric power grids and regulatory constraints, the effectiveness of coupling between the power line and PLC transceivers has become a very important issue. Coupling devices used to inject or extract data communication signals into or from power lines are very important components of a PLC system. There is, however, an obvious gap in the literature for a detailed review of existing PLC couplers. In this paper, we present a comprehensive review of couplers, which are required for narrowband and broadband PLC transceivers. Prevailing issues that protract the design of couplers and consequently subtended the inventions of different types of couplers are clearly described. We also provide a useful classification of PLC couplers based on the type of physical couplings, voltage levels, frequency bandwidth, propagation modes and a number of connections. This survey will guide researchers, as well as designers alike, into a quicker resourcing when studying coupling in narrowband and broadband PLC systems.

The high amount of applications to be implemented in the Smart Grid requires bi-directional connectivity between a multitude of nodes with a reliable, high speed, low latency, energy efficient and cost effective communication technology. Power line communication (PLC) has the potentiality to meet the requirements. Indeed, there exists space for PLC technology improvements and to overcome the challenges mostly due to a hostile communication medium. There are two considered frequency spectra: a narrowband (3-500 kHz) spectrum and a broad band (1.8-86 MHz) spectrum that are exploited by current technology. In this paper, we discuss the usage of these spectra both in LV and MV networks, highlighting pros and cons and advocating the realization of an adaptive technology that can cognitively make the best usage of available resources so that the requirements of reliability, latency and coverage can be met.

“…Therefore, the bandwidth of this key signal can be relatively small. When using PLC communications, those two sets can be combined into one [26]- [28]. The header has both sender address and receiver address, so the digital electric power can be transferred to the given address passing through the specified intermediate DGRs.…”

Abstract-To support a high penetration of intermittent solar and wind power generation, many regions are planning to add new high capacity transmission lines. These additional transmission lines strengthen grid synchronization, but will also increase the grid's short circuit capacity, and furthermore will be very costly. With a highly interconnected grid and variable renewable generation, a small grid failure can easily start cascading outages, resulting in large scale blackout. We introduce the "digital grid," where large synchronous grids are divided into smaller segmented grids which are connected asynchronously, via multileg IP addressed ac/dc/ac converters called digital grid routers. These routers communicate with each other and send power among the segmented grids through existing transmission lines, which have been repurposed as digital grid transmission lines. The digital grid can accept high penetrations of renewable power, prevent cascading outages, accommodate identifiable tagged electricity flows, record those transactions, and trade electricity as a commodity.
