Gestión de la demanda de vehículos eléctricos, en función del perfil de voltaje de la red

Abstract

Global warming and climate change were generated, among other causes, by using vehicles for transportation using fossil fuels, which emit large amounts of toxic greenhouse gases, and are leading to their replacement by electric cars. In Ecuador, under current conditions, the massive implementation of electric vehicles should not jeopardize the quality of electric service of the Energy Distribution Companies. From the analysis of the voltage profile in the distribution network of Empresa Eléctrica Regional Centro Sur, it has been verified that the voltage profile in the secondary networks varied inversely proportional to the network load, without this meaning a breach of product quality since they are variations within the band considered acceptable (±8%). In this context, this proposal proposed a solution that would reduce the impact on supply quality through a model that will manage the EV demand autonomously, processing input signals (secondary voltage profile) and delivering control signals to vary the EV’s power. The proposal contemplated the research, development, and simulation through software (Open DSS) of such a model. It performed a case study by extrapolating the massification of this application on an electrical grid.
