“…The technological development of large-scale integrated circuits, which led to the current availability of advanced, fast, and powerful microprocessors, has resulted in the development of automated digital substations which, by utilizing IEDs, are able to perform functions, such as local and remote monitoring, equipment supervision, etc. Furthermore, the use of digital technology improved the interoperability and communication between devices of different suppliers and technological generations [48,49]. The specific technology, which is also referred to as the process bus, contributed to the interoperability between heterogeneous systems and the configuration of functions that are based on open architecture to make the system viable.…”

“…The above goals can be accomplished by standardizing the synchronization process of IEC 61850-9-2 functions as well as wideband technologies that support quality of service (QoS), such as 5G telecommunication networks [50,51]. Concluding, IEC 61850 is the only international standard for substation automation that is based on open architecture and incorporates specifications for sampling and timing synchronization based on IEEE 1588 in local and in wide area networks [14,49].…”

“…The standards that support these requirements are IEC 61850-7-410 and IEEE P2030.2 [67], while there are not any standards for storage devices other than hydroelectric (IEC 61850-7-410) [49]. Moreover, no appropriate specifications have been yet developed regarding the amount and type of data to be exchanged between smart grid and energy storage systems.…”

Upgrading the existing energy infrastructure to a smart grid necessarily goes through the provision of integrated technological solutions that ensure the interoperability of business processes and reduce the risk of devaluation of systems already in use. Considering the heterogeneity of the current infrastructures, and in order to keep pace with the dynamics of their operating environment, we should aim to the reduction of their architectural complexity and the addition of new and more efficient technologies and procedures. Furthermore, the integrated management of the overall ecosystem requires a collaborative integration strategy which should ensure the end-to-end interconnection under specific quality standards together with the establishment of strict security policies. In this respect, every design detail can be critical to the success or failure of a costly and ambitious project, such as that of smart energy networks. This work presents and classifies the communication network standards that have been established for smart grids and should be taken into account in the process of planning and implementing new infrastructures.

“…In order to extract all the potential that automation can provide for the electricity distribution grid, it is important to take this concept also to primary substations [2], [7]. Many substations nowadays are outdated, with obsolete equipment installed, such as electromechanical relays, and it is necessary to modernize it to meet the new demands of the electricity sector [8].…”

“…A protection system of the electric power distribution grid is considered well configured, when it, in failure situations, performs the isolation of the section of the electric power distribution grid only on the components that are defective, optimizing for the smallest number of unattended consumers and keeping the rest of the electricity distribution grid stable and with energy supply [6], [7]. There can be many reasons for failures in the electricity distribution grid, from adverse weather conditions and collisions of vehicles on distribution poles, even failure in the electricity distribution grid equipment due to overload or operation outside the nominal levels of voltage and frequency [6].…”

With the advancement of technology and the application of new sensors in the electric distribution grid, in order to increase its automation, meeting the idea of smart grids, a concept that has been expanding through the years. This article describes some of the solutions and results that ENEL Distribution São Paulo has achieved, through its R&D (Research and Development) Urban Futurability project, to make its electricity distribution grid automated and in line with trends and future technologies. The project includes the installation of sensors for monitoring and protecting both the overhead and underground electricity distribution grid and medium and low voltage, digitalization of the primary substation and improvements in the communication infrastructure, seeking their complete automation. The project was applied in one of the largest urban centers in the world, the city of São Paulo, Brazil, with a diversity of load profiles, both residential and commercial, being a great place to test new technologies in different scenarios. With the increased application of automation in the electricity distribution grid, ENEL Distribution São Paulo seeks to provide its customers with a better service, with a safer and more reliable electricity distribution grid, monitored practically in real time and with state-of-the-art technologies. Therefore, the end consumers benefit from an electric distribution grid with greater availability and decreased number of interruptions.INDEX TERMS Distribution transformer sensing, fiber optic communication, fuse sensing, grid automation, primary substations digitalization, protection in the low voltage grid, underground fault tracking.
