## 6 Conclusions
New equipment is being developed, which will allow smart metering, supported by the appropriate communications architecture. This advanced metering will allow the interaction with the final clients, who will be able to take part in the decisions of the SG. The measure of future will allow the integration of the great forgotten in the electrical grids, the low tension; new developments of low voltage protocols will allow the supervisionand control of it, and why not, the integration of renewable generation sources and their management through Smart Metering. The SG is presented as an integrator of new equipment, new tools, new protocols, new systems, new paradigms, greater integration of renewables, etc. All of the above will make the current networks become the future SGs, and the term Smart can be decisive and fundamental in them. This document demonstrates the need for the evolution of the current electrical infrastructure. This need is due to the constant evolution of the electrical system. This evolution implies the appearance of new actors on the stage, namely: DG, DR, microgrid, EV, etc. The above will make it a necessary improvement in the industry related to the electrical infrastructure, now called SG. The appearance of new devices in the infrastructure should be supported by the development of new planning, management and simulation tools. Both the new hardware and the software will be supported by the latest trends in design and development models, specifically models based on advanced techniques (AI and similar); however, some authors continue using models based on classical systems (linear, differential, etc.). But everything has its advantages and disadvantages, AI-based techniques allow to find a quick solution to problems, but on the contrary you lose control over it; on the other hand, techniques based on linear techniques make it difficult to find the solution quickly (they need to know the problem very well), but on the contrary, they make the user perfectly understand the problem to be solved. The current electrical infrastructure is evolving, since it incorporates new elements such as DG, DR, microgrids, etc. ; this fact will require the current infrastructure to evolve and become a more flexible infrastructure. The traditional electrical and electronic devices will require a more novel and ambitious development. In this sense, it is possible that the current industry shows some reluctance to achieve this, but step by step, the electrical industry will accept and demand these changes.
