“…Based on our previous experiences with the deployment of repeaters in PLC networks and their impact on network performance, we found out that repeaters in specific cases had a large impact on throughput and latency. Compared to results published in [62], we experienced more significant drop, especially in terms of throughput of the whole network. This outcome lead us to further research the impact of repeaters.…”

“…In comparison, the TCP throughput tool test showed results close to those of Method 1/2, but only with a more significant drop for the first couple of hops. We also compared our results in terms of throughput drop caused by the repeater to outcomes of another study [62]. As we experienced before, when we tested PLC networks, our measurements showed a more significant throughput drop.…”

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.

“…Some authors propose the development of a new IED for protections in substations, such as the one presented by Lim and Sidhu [168]. A new fault recognition system is proposed by Kapareliotis et al [169], and study the signal-to-noise ratio of the electric line. By means of intelligent sensors, it is possible to design a new self-healing strategy, as shown by You et al [170].…”

New technological advances based on software, hardware and new materials must be implemented in smart grids. In addition, these advanced electrical grids must incorporate elements of artificial intelligence. Advances in software development must be complemented with the development of new hardware (power electronics and active distribution among others). The aforementioned must rely on the development of new materials and sensors, which should be integrated into the smart grid. Therefore, the four areas of research based on the technologies are: Operation and Control, Maintenance and Lifespan Management, Grid Planning and Design, and Metering. The review presents the algorithms, materials, devices and others paradigms applied to smart grids, classifying the works according to the four areas of research. This review has focused on the four fundamental pillars of smart grids, on the one hand, the need for more efficient operation and control, followed by advanced maintenance management, to continue planning and designing the new grids, and for conclude with the advanced measurement. As you will see in the article, new devices, new techniques, and future scenarios will make possible the transition from the current grid to the future smart grid.

“…There are numerous works done on these subjects. For example, [4] deals with finding the correlation between faulty equipment on the power networks, and the signal-to-noise ratio of the power-line signal induced, thus showing the possibility of developing a new method of faulty loads recognition in power networks. In [5], current decomposition provides a suitable approach to determine how disturbances propagate among circuits.…”

In this paper the process of extracting a set number of features that uniquely describe a nonlinear load is described. The method is used for classifying and identifying as well as determining the operation state of harmonic nonlinear loads. The method is based on harmonic spectral decomposition of periodic waveforms and on sorting and calculating the features by means of Currents' Physical Components Theory. Using this theory enables to create features with physical meaning and to enable to calculate the actual various currents and powers of these loads.
