“…According to MTL theory [27], the 1 n× voltage phasor vector V and 1 n× current phasor vector I can be expressed as (1) where z denotes the position at the conductors. The 1 n× matrices + m V and − m V denote the forward and backward modal voltage vectors, respectively.…”

Modelling and estimating power-line communication (PLC) channels are complicated issues due to the complex network topologies, various junctions, and changeable loads. This paper focuses on the frequency response characteristics (FRCs) of medium-voltage (MV) PLC networks with special consideration of two scenarios that are often neglected but generally exist. In the first scenario, the MV distribution network is of the ring topology. In the second scenario, the MV overhead lines and underground cables join at junctions, and the shields of underground cables are grounded with nonzero grounding impedances at the junctions. These conditions lead to the failure of currently popular methods to different degrees. For this reason, we developed an effective method to calculate the FRCs of distribution networks for PLC applications. With this method, the frequency responses of nodes are simply expressed as the binary function of the overall tube propagation matrix and overall node scattering matrix, which is convenient for calculations and analyses. The proposed method was validated by the agreement between the calculated and measured FRCs. The results of two test examples showed that the proposed method performed better in comparison with the traditional approximate method when nonideal grounding conditions were taken into account. The proposed method is also independent of the network topology, so it can adapt to the dynamic changes of the network structure.

“…NB-PLC is suitable for the collection of power usage data and so can be used to provide SM services within businesses and residences via HANs. Modulation schemes for PLC communications include binary phase shift keying (BPSK), frequency shift keying (FSK), spread frequency shift keying (S-FSK), spread spectrum (SS), orthogonal frequency division multiplexing (OFDM) or a combination of these techniques [13]. Media access control (MAC) protocols include carrier sense multiple access (CSMA) with collision avoidance (CSMA/CA) and time division multiple access (TDMA).…”

Smart meters (SMs) are key components of the smart grid (SG) which gather electricity usage data from residences and businesses. Home area networks (HANs) are used to support two-way communications between SMs and devices within a building such as appliances. This can be implemented using power line communications (PLCs) via home wiring topologies. In this paper, a bottom-up approach is designed and a HAN-PLC channel model is obtained for a split-phase power system which includes branch circuits, an electric panel with circuit breakers and bars, a secondary transformer and the wiring of neighboring residences. A cell division (CD) method is proposed to construct the channel model. Furthermore, arc fault circuit interrupter (AFCI) and ground fault circuit interrupter (GFCI) circuit breaker models are developed. Several HAN-PLC channels are presented and compared with those obtained using existing models.Energies 2018, 11, 3344 2 of 20 (RTP) allows appliances such as dishwashers, washing machines and dryers to be operated during off-peak times when prices are low [8]. This can also be used to reduce HVAC and water heater costs. Energy theft prevention is another function of SMs. With advanced theft detection and encryption algorithms, SMs can detect and report, as well as prevent illegal electricity usage [9]. Appliance monitoring can also be provided by regularly checking and reporting the status of appliances. Power suppliers can also benefit from SMs as meter data can be obtained remotely which is more cost efficient than manual reading. Power line communications (PLC) can be employed for SM services via a home area network (HAN) [10]. Since the power distribution system was not originally designed for communication purposes, the modeling of power lines as communication channels is critical to the design and analysis of HAN PLC.

“…Table 2 summarizes the main characteristics of these standards. A wired communication media frequently-used in SDNs (particularly in AMI) is the power line communication (PLC), since it combines the electric power distribution line with the data signal [119,126]: PLC acts by modulating carrier signals directly on the power cables. PLC represents an alternative broadband networking infrastructure without installing dedicated and expensive network wires such as twisted pair cables or fiber optics.…”

Electric power systems are experiencing relevant changes involving the growing penetration of distributed generation and energy storage systems, the introduction of electric vehicles, the management of responsive loads, the proposals for new energy markets and so on. Such evolution is pushing for a paradigm shift: the management must move from traditional planning and manual intervention to full "smartization" of medium and low voltage networks. Peculiarities and criticalities of future power distribution networks originate from the complexity of the system that includes both the physical aspects of electric networks and the cyber aspects, like data elaboration, feature extraction, communication, supervision and control; only fully integrated advanced monitoring systems can foster this transition towards network automation. The design and development of such future networks require distinct kinds of expertise in the industrial and information engineering fields. In this context, this paper provides a comprehensive review of current challenges and multidisciplinary interactions in the development of smart distribution networks.
