“…Communications by PLC (Power Line Communication) are currently experiencing a boom, as they offer the possibility of building a very high-speed home local network using the existing electrical infrastructure of buildings [1][2][3]. However, the PLC transmission channel is a difficult environment, as the different branches of the network produce multipaths similar to the propagation conditions of wireless networks [4,5].…”

A solution that today interests a good number of industrialists consists in using the most dense and ubiquitous network: the electricity network. Communication over energy line, commonly known as PLC (Power Line Communications), makes it possible to consider a completely different type of electrical local loop. The main advantage of such a network relies to the ubiquity of the infrastructure, both inside and outside buildings, thus, making it possible to considerably limit the costs of network deployment. One of the options chosen to increase throughput on the PLC networks is the use of OFDM (Orthogonal Frequency Division Multiplexing). This modulation allows optimal use of the frequency band, while providing very good resistance to interference. However, one of the problems with these modulations is the cardinal sinus frequency response of the transmitter and receiver filters. Thus, the idea of using filters other than rectangular filters can be considered to overcome this problem. In this direction, oversampled OFDM modulation has been proposed in this work. The main objective of this paper is to analyze the performance of the oversampled OFDM modulation in terms of the PSD (Power Spectral Density) and the BER (bit error rate). From simulation, we can conclude that the performance of the oversampled OFDM technique surpasses the conventional OFDM in terms of BER and PSD.

“…The mesh grid topology is based on closed loops where power might be delivered to nodes through different lines; thus, this topology performs with higher reliability through higher complexity and higher costs [15][16][17]. The issue of performance and availability of the whole communication system depending on network topology is being further discussed in [18,19]. A BPL solution could be deployed in both segments of the power grid-LV (low voltage) and MV (medium voltage) [20,21].…”

Broadband over Power Lines (BPL) is considered a promising communication technology in the concept of Smart Grids. This paper evaluates networks based on BPL, with a focus on the impact of repeaters in the linear topology of distribution substations. In large-scale Smart Grids network planning, positions of repeaters have to be carefully chosen. This article should help to determine such positions and limitations of BPL linear topology networks. Laboratory and on-field measurements and their results are presented in this article. Results show the impact of repeater’s deployment for different testing methodologies also with regard to other already presented studies. Measured values and the determined impacts of repeaters are later used as input data for simulation of the linear BPL topology in terms of network throughput with multiple streams and bottlenecks. These occur especially on lines shared by multiple communicating nodes. Furthermore, the simulation investigates the balancing time of multiple data streams throughput. The simulation shows that the throughput balancing can occupy a significant time slot, up to tens of seconds before the throughput of different streams balances. Also, the more data is generated, the more time the balancing time takes. Additionally, the throughput drop caused by a repeater is determined into the range of 35–60%. Based on the measurement and simulation results, lessons learned are presented, and possible performance improvements are discussed.

“…The smart grid, as a modern electrical network (EN) infrastructure, can enhance the efficiency, reliability, and security of traditional ENs based on the advancement of cyber-physical systems [1][2][3]. In a smart grid, the monitoring, control, and management of the EN depend closely on the smart information and communication (cyber) network [4][5][6], which works such that the EN ensures not only its own secure operation but also reliable operation of the entire communication network. Meanwhile, when the EN fails (especially, through cascading failure), fault cross-propagation between the electrical and communication networks (ECNs), called interdependent network, occurs, which increases the complexity of fault propagation owing to interactions between the ECNs.…”

Communication networks as smart infrastructure systems play an important role in smart girds to monitor, control, and manage the operation of electrical networks. However, due to the interdependencies between communication networks and electrical networks, once communication networks fail (or are attacked), the faults can be easily propagated to electrical networks which even lead to cascading blackout; therefore it is crucial to investigate the impacts of failures of communication networks on the operation of electrical networks. This paper focuses on cascading failures in interdependent systems from the perspective of cyber-physical security. In the interdependent fault propagation model, the complex network-based virus propagation model is used to describe virus infection in the scale-free and small-world topologically structured communication networks. Meanwhile, in the electrical network, dynamic power flow is employed to reproduce the behaviors of the electrical networks after a fault. In addition, two time windows, i.e., the virus infection cycle and the tripping time of overloaded branches, are considered to analyze the fault characteristics of both electrical branches and communication nodes along time under virus propagation. The proposed model is applied to the IEEE 118-bus system and the French grid coupled with different communication network structures. The results show that the scale-free communication network is more vulnerable to virus propagation in smart cyber-physical grids.
