“…This new index was obtained and shown in Figure 5 as the "Optimized Solution" for taps configuration, which only demonstrates the capability of the methodology when combined with smart methods of voltage control [9]. Obviously should also be evaluated gains in quality compared to the wear caused by switching a tap in order to obtain the best voltage profile at the lowest possible wear of the equipment.…”

The recent technological advances included in the distribution systems, such as the use of supervisory systems, automation and the emergence of the smart meters brings many possibilities for improvement in the methodologies used in the operation of these systems. This paper proposes a methodology for using state estimation techniques and error detection in smart grids, through measures in the MV network and smart meters to evaluate the voltage profile of the feeder. This evaluation is obtained by calculating an index that analyzes the voltage levels at nodes of consumers according to the ranges appropriate, precarious and critical, further penalizing violations in loads with higher priority or that are in this condition for a long time. The methodology for evaluation can be used to predict the scenarios when changing settings in voltage regulators, seeking to supply energy with a higher quality, thereby increasing consumer satisfaction.

It is being discussed in the global energy sector the introduction of new technologies and regulatory changes in the distribution systems of electric power, in this sense the present work aims to present a methodology for analysis and optimization of the voltage levels, from the recurrence of preview techniques applied to the setting of Smarts Grids. The results obtained in the simulations we can say that the advent of Smarts Grids enables the exploration of artificial intelligence techniques to predict voltage. The proposed methodology has resulted in the indication of the need to proactively intervene in the operation of voltage control equipment.
