Abstract
This paper assesses the impact of measurement differences on the spectral efficiency (SE) of distribution broadband over power lines (BPL) networks when CS2 module is applied. The broadband performance of distribution BPL networks is investigated in the 3-88 MHz frequency range when appropriate injected power spectral density limits (IPSD limits) and uniform additive white Gaussian noise (AWGN) PSD levels from the BPL literature are assumed. The impact of measurement differences on SE of the distribution BPL networks is here assessed through appropriate SE metrics. These SE metrics assessing this impact are detailed in order to act as the benchmark metrics of the countermeasures techniques against measurement differences of the companion paper.

Highlights
Smart grid allows the transformation of today’s power grid to an advanced IP-based power network with a plethora of relevant broadband applications
Among the available communications technologies that can interoperate under the aegis of the smart grid, a significant role can be played by the broadband over power lines (BPL) technology that exploits the already installed power grid infrastructure [10]-[12]
As already been mentioned in [25]-[32], measurement differences between the experimental and theoretical results occur during the transfer function determination of distribution BPL networks that further affect the computation of all the derivative spectral efficiency metrics, such as capacity and SE
Summary
Smart grid allows the transformation of today’s power grid to an advanced IP-based power network with a plethora of relevant broadband applications. On the basis of broadband performance metrics supported by the hybrid method such as coupling channel attenuation, capacity and SE, the impact of CS2 module on the performance of the distribution BPL networks has been assessed in [24]. As already been mentioned in [25]-[32], measurement differences between the experimental and theoretical results occur during the transfer function determination of distribution BPL networks that further affect the computation of all the derivative spectral efficiency metrics, such as capacity and SE. These measurement differences are due to a number of practical reasons and “real-life” conditions.
