“…In smart grids, such high data rates as provided by HomePlug AV are not needed, and thus, the data rates and design complexity are reduced in the GP [8]. In this paper, the objective is to study the applicability of HomePlug GP in the LVDC PLC concept, and whether it provides an improvement in the performance compared with the HomePlug 1.0 modems, which were tested for the PLC concept in [5], [7].…”

“…An ICT system is also needed in a low-voltage direct current (LVDC) electricity distribution system. The LVDC smart grid concept is presented in [3], [4], and a highfrequency (HF) band PLC concept based on the HomePlug 1.0 specification has previously been proposed and tested for the LVDC system [5]- [7]. It has been shown that HomePlug 1.0 could be suitable for the LVDC system, while the signal is repeated every 500 meters in the cable network.…”

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.

“…Medium voltage (MV) is transformed, rectified and filtered to low-voltage DC, which is distributed to customers with underground low-voltage cables (UGC). Each customer is equipped with a customer-end inverter (CEI), which is implemented with switched-mode power electronics [12]. Inverted and smoothed ~230 VAC from the DC is supplied to customer loads.…”

It has been shown that high-frequency (HF) band power line communication (PLC) is a feasible data transmission method for a smart grid concept, namely for a low-voltage direct current (LVDC) electricity distribution system. However, because of the signal attenuation, the communication distances in the LVDC grid are limited with the HF band PLC. Hence, the new narrowband (NB) PLC should also be tested for the concept. In this paper, the PLC channel analysis in the LVDC system is carried out for the novel NB PLC technology, that is, the G3-PLC in the frequency band of 150-490 kHz. For the channel analysis, channel gain and noise signals from the terminals of the PLC couplers designed for the NB PLC are measured. The performance of the G3-PLC is analyzed theoretically and by communication tests. The noise voltages are measured, and communication tests are carried out in the LVDC laboratory system and in an LVDC field installation grid. The results show that NB PLC could be suitable for the concept. Keywords-Low-voltage direct current (LVDC); narrowband (NB); power line communication (PLC); smart grid (SG)
