“…Recently, new interest arises due to the developments regarding multiple-input multiple-output (MIMO) transmission schemes and intraoperability/interoperability of BPL systems [10][11][12][13]. The need to harmonize LV/BPL with MV/BPL systems (intraoperability) is a necessary prerequisite before investigating cooperative communications between BPL systems and other broadband technologies (interoperability) [14,15].…”

Abstract-A complete methodology is employed to determine the transmission characteristics of low-voltage/broadband over power lines (LV/BPL) channels associated with underground power distribution networks, in the light of the multiconductor transmission line (MTL) theory. The established bottom-up approach, already used to treat overhead and underground MV/BPL transmission, is extended to analyze BPL transmission in three-phase N -conductor underground lines with common shield and armor. This analysis shows that these cables may support N + 2 modes, giving rise to N + 2 separate transmission channels which reduce to N +1 if the armor either does not exist or is grounded and to N if the shield is also grounded. In addition to the generalized analysis, a simplified approximation concerning three-phase N -conductor underground cables is also presented. Taking the generalized analysis and the simplified approximation into account, their numerical results concerning attenuation in various underground LV/BPL channels in the frequency range 1-100 MHz are validated against relevant sets of simulations and measurements with satisfactory accuracy and compared to corresponding results of overhead and underground MV/BPL channels. It has been verified that the attenuation in overhead and underground BPL channels depends drastically on power distribution grid type, MTL configuration, and cables used. Moreover, the attenuation in underground LV/BPL channels exhibits a lowpass behavior, is significantly higher than that of overhead MV/BPL ones, and is comparable to that of underground MV/BPL ones. A consequence of the proposed methodology is that it

“…Each of the aforementioned adverse factors critically influences the broadband potential of OV HV BPL networks [19], [22]. Due to the upgrade of the existing SISO BPL networks to MIMO ones across the entire power grid, the development of accurate and efficient models that are suitable for describing either the channel attenuation or the noise of MIMO BPL networks at high frequencies is imperative.…”

“…Here, it should be noted that the hybrid method has been already successfully tested in transmission and distribution MIMO BPL networks [13], [26]. In fact, this hybrid method is based on: (i) a bottom-up approach that consists of the MTL theory and various similarity transformations, such as eigenvalue (EVD) and singular value (SVD) decompositions [3], [10], [11], [19], [23], [25], [27], [28]; and (ii) a top-down approach, which is denoted as TM2 method, that is determined through the concatenation of multidimensional chain scattering matrices of the MIMO BPL network modules [2]- [11], [24], [27].…”

Extending the analysis already presented in [1], this paper considers broadband potential of overhead (OV) transmission multiple-input multiple-output (MIMO) broadband over power lines (BPL) networks when different noise conditions occur and different well-proven noise models are adopted. The contribution of this paper is two-fold. First, the broadband potential of a great number of indicative OV high-voltage (HV) BPL topologies and of MIMO transmission schemes is studied in terms of appropriate capacity metrics. The relevant numerical results reveal the significant dependence of ΜΙΜΟ capacity metrics on noise conditions. Second, various well-known BPL noise models from the literature are compared on the basis of their achieved OV HV MIMO BPL capacity. Through the careful study of the capacity results of noise models, it is demonstrated that spectrally flat additive white Gaussian noise (AWGN) may be comfortably assumed as an efficient noise model in transmission MIMO BPL networks. Also in MIMO BPL networks, the comparative capacity analysis of noise models shows small differences among them in the 3-88MHz frequency range.

“…Apart from the fervent interest towards the adoption of BPL technology in future's SG installations, new interest arises due to the recent developments regarding multiple-input multiple-output (MIMO) [31]- [33]. Since today's single-input single-output (SISO) HV/BPL systems lack of providing adequate transmission rates so as to cover future SG application requirements in a trustworthy way, the deployment of MIMO configuration schemes in overhead HV/BPL networks, which is firstly presented in [14], [32], [34]- [41], is imminent.…”

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.
