“…In NB PLC for smart grid applications, research effort is spent to increase robustness and coverage, for instance, looking at increased spectrum usage, possibly beyond 148 kHz, or exploiting better coupling techniques that can resolve the limitations due to the low line impedance and high noise [128]. In BB PLC, one question is how to go beyond the current high throughput offered to support very high speed multimedia services and home networking applications.…”

In recent decades, power line communication has attracted considerable attention from the research community and industry, as well as from regulatory and standardization bodies. In this article we provide an overview of both narrowband and broadband systems, covering potential applications, regulatory and standardization efforts and recent research advancements in channel characterization, physical layer performance, medium access and higher layer specifications and evaluations. We also identify areas of current and further study that will enable the continued success of power line communication technology.essentially concerned with coexistence with other systems that also use the power grid (i.e. machines and appliances that draw electricity) and wireless systems operating in the same frequency bands as PLC. The frequency range used for today's PLC solutions starts as low as 125 Hz and reaches as high as 100 MHz. A useful classification of PLC systems according to frequency bands has been introduced in [28]: it distinguishes between ultra-narrowband (UNB), narrowband (NB) and broadband (BB) PLC systems, operating between about 125-3000 Hz, 3-500 kHz and 1.8-100 MHz, respectively. Most recent developments in standardization and regulation activities over the past 20 or so years apply to NB and BB PLC systems, and we will focus on these in the following.

“…Impedance values may also vary between rural and urban areas [27,28] due to the different grid topologies and the higher number of customer loads connected to the grid in the urban environments. For long cables and high frequencies, the line impedance is dominated by the characteristic impedance of the cable [32]. Lastly, the connection/disconnection of the consumer loads, and their inductive or capacitive behavior, causes a variation in time of the grid impedance.…”

The paper presents and evaluates three advanced methods for the characterization of the low-voltage (LV) grid access impedance for the frequency range assigned to Narrow Band-Power Line Communications (NB-PLC): 9 kHz to 500 kHz. This study responds to the recent demand from both regulatory bodies and Distribution System Operators about the need for accurate and validated methods for this frequency band, due to the limited knowledge of the impedance values in the electrical grid and their influence on NB-PLC transmission channels. In this paper, the results of a collaborative work to develop different proposals to overcome the challenges for the proper characterization of the frequency and time-varying grid impedance, from different theoretical approaches, are presented. The methods are compared in a controlled and isolated scenario: the impedance characterization of passive filters. Then, the results are validated two-fold: first, against theoretical simulations, based on the schematics provided by the manufacturer, and second, against the measurement results of a precision impedance meter, used as a reference of accuracy. The results demonstrate a high degree of precision of the three proposals to characterize the access impedance of the LV grid.
