The main purpose of this paper is to study and evaluate the use of induction voltage regulators in distribution networks with several sources of renewable distributed generation. Because this type of generation is not steady and is dependent on weather conditions, such as wind and solar irradiation, the voltage at several points of a network may exhibit significant variation. Therefore, conventional voltage regulators will be subject to a larger number of tap changes, which shorten their useful lifetime. In this context, an induction voltage regulator, which has not been explored in the literature, is an alternative that can overcome this problem, since it can maintain a constant voltage level in the output without its components wearing out.
