HomePlug green PHY for the LVDC PLC concept: Applicability study

It has been shown that high-frequency (HF) band power line communication (PLC), that is, the HomePlug 1.0 specification, is feasible for a low-voltage direct current (LVDC) smart grid (SG) system, where power electronics and low-voltage DC are applied to the electricity distribution. In this paper, the applicability of the latest HomePlug specification, Green PHY (GP), is studied within the LVDC PLC concept.

Channel characteristics between 2-30 MHz in the HomePlug GP frequency band and noise in the channel from the terminals of the PLC couplers are measured. Furthermore, data transmission tests with HomePlug GP compliant modems are carried out in the LVDC laboratory setup and on the LVDC research site.
