Considering the current evolution of electric power systems and the gradual implementation of distribution automation resources, telemetry, advanced algorithms for reconfiguration, load forecasting, micro and distributed mini generation, among others, voltage control has a fundamental role in the application and maintenance of these important resources in distribution system [1], [2]. The execution of maneuvers for the reconfiguration of feeders is a common and necessary activity in urban feeders, generally represented by shorter and more heavily loaded networks. On the other hand, rural or more extensive feeders, who serve several smaller municipalities throughout their area of operation, generally have their topology altered due of eventual contingencies or in cases of scheduled shutdowns. In these cases the voltage regulators must have their adjustments previously evaluated for these different operating conditions [3], [4], [5]. In addition, the seasonal variations of the load and the changes occurring throughout the day such as the transitions between the load levels, presence of distributed generation, the exit of large blocks of load at peak times and the return of these same loads after the end of the hourly range due time of use tariffs, have a significant impact on voltage levels [6], [7]. This paper presents the developments that are being carried out by State Electricity Distribution Company (CEEE-D) and Federal University of Santa Maria (UFSM) with incentives from the Electrical Energy National Agency through ANEEL Research and development (R&D) project ANEEL Code PD5707-4301/2015 named “Intelligent Dynamic Control for voltage regulators and supervisory systems (CDI-RT) in a smart grid environment”. This R&D project continues the evolution process and maturation of research carried out in the R&D project finished in 2013 named “Efficient use of the innovative potential of smart grids in the improvement of the management of the quality of electric energy in distribution systems”, developed by Federal University of Santa Maria (UFSM) and CEEE-D. The objective is to develop a head series design of an intelligent dynamic controller for voltage regulators (CDI-RT) that can operates automatically based on the commands coming from the developed methodology. The aim is to contribute to increase the operational efficiency of the voltage regulators installed in the distribution systems and improve the quality of the offered services, reduce the costs associated with the displacements of teams for parameterization and adjustments of the voltage regulators and reduction of penalties for voltage levels violations. The TAP Eletro Company is a partner of this project and will contribute in the manufacture of the head series design.
