“…With reference to Fig. 2, the transmitting and the receiving ends are assumed matched to the characteristic impedance of the modal channels, whereas the branch terminations are assumed open circuit [1,2,4,5,7,8,12,17,[48][49][50][51]58].…”

“…3(a) and in accordance with, the simulations of various overhead HV/BPL topologies unveil the potentially excellent communications medium of overhead HV grid when BPL connections deployed even over a 25 km repeater span well beyond 88 MHz. The fact that overhead HV/BPL lines resemble a low-loss flat-fading transmission system with highcapacity characteristics shows as an attractive broadband last mile alternative and SG backbone solution [1,2,5,7,48,51].…”

Abstract-This paper considers broadband signal transmission via high-voltage/broadband over power lines (HV/BPL) channels associated with overhead power transmission. To determine the end-to-end channel characteristics of various overhead HV/BPL multiconductor transmission line (MTL) configurations, the chain scattering matrix or T -Matrix (TM) method is adopted.The overhead HV/BPL transmission channel is investigated with regard to its spectral behavior, its end-to-end signal attenuation, and phase response. It is found that the above features depend critically on the frequency, the coupling scheme applied, the physical properties of the cables used, the MTL configuration, and the type of branches existing along the end-to-end BPL signal propagation. Unlike the older models that underestimate the broadband transmission potential of overhead HV lines significantly, the results demonstrate that the overhead HV grid is a potentially excellent communications medium, offering low loss characteristics over a 100 km repeater span well beyond 100 MHz and guarantees the imminent coexistence of lowvoltage (LV), medium-voltage (MV), and HV BPL systems towards a unified transmission/distribution smart grid (SG) power grid.

The impact of different environmental policies on the broadband performance of overhead multiple-input multiple-output high-voltage/broadband over power lines (MIMO/HV/BPL) networks is investigated in this paper. The examined environmental policies focus on the carbon energy footprint reduction of overhead MIMO/HV/BPL networks while respecting their broadband character. The contribution of this paper is three-fold. First, the spectral and environmental performance of various configurations and topologies of overhead MIMO/HV/BPL networks is assessed with regard to respective spectral efficient (SE) and newly presented environmental efficient (EE) metrics. Second, further insights regarding the performance of overhead MIMO/HV/BPL networks highlight the better spectral and environmental performance of these networks against other today's overhead HV/BPL networks, such as single-input single-output (SISO), single-input multiple-output (SIMO), or multiple-input single-output (MISO) ones. Third, the definition of appropriate environmental policies that optimize the coexistence of the three main sectors of concern, which are the Quality of Service (QoS) requirements, protection of existing radioservices and promotion of environmentally aware limits, is promoted. Towards that direction, the proposed SE/EE trade-off relation of this paper is expected to prove an extremely helpful SE/EE optimization technique.
