Consideration on the effects of DERs in the PLC communication channel

Abstract

In the intend to use the transmission and distribution power lines as a communication channel, much attention has been provided in the modeling of the transmission media used for the propagation of the signals that transmit the information. Most of this effort has been applied in the broadband propagation characteristics, due to higher bandwidth and the use of higher frequencies that can avoid some interference [1]. In this paper it is proposed a method to better understand parameter differences between line characterization in the different frequencies of interest for Power Line Communications (PLC) applicable to analytically determine the channel model, by analyzing the effects of reflections due to the nodes and branch lines impedance mismatches that are present at the distribution power lines. Nowadays such methodology is empirically determined, so this new approach intends to facilitate the modeling methodology prior to its implementation.
