“…In more details, the centralized RES units typically infuse energy in the power networks of high and extra high voltage levels. Hence, the produced energy is subject to significant transmission and distribution losses as well as losses related to increased investment costs due to the required infrastructure in rural areas [7,8]. As a result, various efficient and reliable power electronic conversion solutions and effective driving techniques have been developed for the connection of RES units to the distribution level [9,10,11,12,13,14,15].…”

In this paper, the efficiency of cooperative communications in power distribution networks is investigated, where a number of renewable energy sources (RESs) are deployed. Specifically, any medium voltage (MV) bus of the power distribution network is considered as a wireless relay node where the information gathered from each MV bus can be reliably transmitted to a control station for further processing. Therefore, the power distribution network can be equivalently considered as a cooperative communication network. The average bit error rate of the proposed cooperative diversity network is studied and a closedform lower bound is analytically derived. Numerical results corroborate the tightness of the proposed bound compared to the Monte Carlo simulations. The proposed wireless communication scheme enables the increase of the RES penetration level in distribution networks, improving so RES exploitation.

“…Moreover, due to different sun-paths throughout the year, the shadow patterns on surfaces are constantly evolving, making this a very complex problem of systems optimization. AC modules with micro inverters are also an alternative to conventional string based systems (Kurokawa et al, 1997). They hold the advantage of being immune to output power drop when a module is shaded and are also immune to mismatch losses.…”

“…More specifically, the centralized RES units typically infuse energy in the power networks of high and extra high voltage levels. As a consequence the produced energy experiences substantial losses related to transmission and distribution as well as economic costs due to the need for non-trivial infrastructure capital investment in non-dense rural and remote areas [4]. Recalling that the contribution of RES units in the overall power network is increasing and anticipating that the corresponding levels will be over 20 %, the aforementioned effects are undoubtedly non-negligible and must be addressed effectively.…”

In this work, a novel performance analysis method for evaluating the robustness of emerging power distribution networks (PDNs), which involve deployable renewable energy sources, is proposed. This is realized with the aid of the outage probability (OP) criterion in the context of cooperative communications, which is widely considered in modern wireless communication systems. The main usefulness of this method is that it allows the involved components to communicate to each-other by means of a robust and flexible wireless sensor network architecture. In this context, any conventional medium voltage (MV) bus of the PDN is represented as a wireless relay node where data signals gathered from each MV bus can be forwarded reliably to a control station for the subsequent processing. The received signals at wireless nodes are decoded and then forwarded to ensure minimal errors and maximal robustness at the receiving site. The considered OP analysis denotes the probability that the power of a received information signal drops below a pre-defined threshold which satisfies the acceptable Quality of Service requirements of a reliable signal reception. To this end, simple closed-form expressions are proposed for the OP of a regenerative cooperative-based PDN in the presence of various multipath fading effects, which degrade information signals during wireless transmission. The offered results are rather simple and provide meaningful insights for the design and deployment of smart grid systems.
