“…In SG applications, ICT is their key aspect while among the available ICT solutions, BPL technology presents some natural advantages that render the related BPL networks as the most suitable implementation for SG applications [2]. However, BPL networks operate across a hostile medium for communications since transmission and distribution power grid infrastructure and equipment have been designed to deliver power rather than information [1], [3]- [7].…”

In [1], the theoretical framework for the interoperability of DHM, iSHM, mSHM, the definition procedure and the class maps has been first presented for OV LV BPL networks. But the main interest of the first paper has focused on the theory of the OV LV BPL topology footprints of TIM, FIIM and HS-DET method on the class maps. In this paper, the numerical results concerning the application of iSHM, mSHM, the definition procedure and the class maps to OV LV BPL networks are first shown. Then, given the iSHM and mSHM class maps, the footprints of TIM, FIIM and HS-DET method databases for the OV LV BPL topologies are highlighted. Finally, a technique for the detection of branch line faults and hook style energy thefts that is based on iSHM and mSHM footprints is proposed.

“…PLC is seen as a viable communication solution partly due to the far-reaching electric power grid and the low deployment cost compared to other technologies [1]. In medium voltage (MV) distribution grids, PLC is used for realtime smart metering, industrial load switching, data privacy with embedded security requirements, demand side home energy management system, and renewable energy monitoring systems [1]- [3]. In smart home networks, PLC modems with in-built couplers are attached to low voltage (LV) electric power outlets to facilitate data communication by providing broadband Internet access.…”

In this paper, we study the application of cooperative non-orthogonal multiple access (NOMA) in power line communication (PLC) where two users exchange information using a two-way relay (TWR). Under the assumption of perfect and imperfect successive interference cancellation (SIC), we analyze key performance metrics for PLC log-normal channels impaired by impulsive noise. In particular, for delay-limited (DL) and delay-tolerant (DT) modes, approximate closed-form expressions are derived for the user outage probability and user ergodic rate. The analytic results are verified via Monte Carlo simulations. Compared with the conventional orthogonal multiple access (OMA) scheme, the simulation results show that our proposed NOMA TWR enhances the user outage probability and the user ergodic rate performance in the low signal-to-noise ratio (SNR) region. However, this gain diminishes as the imperfect SIC error increases and is non-existent beyond a certain level of imperfect SIC. Furthermore, the system performance is maximized by optimizing the power allocation coefficients where the system throughput and ergodic sum-rate of the NOMA TWR network in DL and DT operation, respectively, are shown to approach a ceiling in the presence of imperfect SIC. The energy efficiency (EE) of the proposed system is also analyzed for DL and DT modes.

Performance Improvement of PLC Channel Estimator and ASCET Equalizer in a FBMC Transmultiplexer Based on a Multi-Core Solution

Power-Line Communication (PLC) employs multi-carrier modulations, such as Filter-Bank Multi-Carrier (FBMC), to improve communications through the PLC channel and provide an efficient use of the spectrum, thus allowing higher data rates. Since one of the main drawbacks is the noisy channel with multipath and frequency-selective fading, the receiver typically includes a channel estimator and equalizer, at the expense of increasing the computational load and complexity of that receiver and making it difficult to obtain realtime solutions. In this context, this work proposes a heterogeneous System-on-Chip (SoC) architecture for the real-time implementation of a FBMC transmultiplexer that involves the channel estimation and equalization at the reception stage. For that purpose, the performance of a multi-core approach is evaluated for both the Zynq® 7000 SoC and the Zynq® UltraScale+ (US+) devices, by using a single-, dual-and quad-core solution to perform the channel estimation and the calculation of the equalizer coefficients in the ARM processor available in the proposed architecture. Two approaches have been analysed for the necessary synchronization among cores; one based on atomic instructions and the other one on interrupts. The dualcore proposal in both Zynq® 7000 and Zynq® US+ provides a x2 acceleration compared to the single-core proposal, whereas the quad-core one in Zynq® US+ does not provide a x4 acceleration as expected, due to the timing overheads of the synchronization among cores imposed by the data dependencies existing in these tasks. Experimental results include the evaluation of the processing times for each task in the algorithm, as well as the acceleration obtained by each proposal. The proposed architecture can be easily applied to other processing algorithms that may take advantage of the parallelism provided by the multi-core approach in a more efficient way, depending on their data dependencies.
