Estudo comparativo para carregamento de carros elétricos através de geração distribuída e análise econômica

Abstract

We are currently experiencing great changes, both in terms of technology, economics and mainly sustainability, which justifies studies on the developmentof new strategies for increasing energy efficiency. Thus, based on clean technologies of residential generation, such as the photovoltaic and consumer system, and the emergence of electric vehicles, this study aims to demonstrate possibilities of applications of these concepts to increase the energy efficiency of a smart home. From the expansion of the smart grid, the search for the consumer through the response of residential demand through the use of the electric vehicle, not only as a means of transportation, but as a source of energy. From a study, different techniques for handling the vehicle loading procedure shown in the literature are verified, in order to understand which is the most effective in terms of economy. Thus, through the simulation of an electric car model and distributed generation, it is possible to establish the economic capacity for energy supply of energy for the home and an electric car, at times when the purchase of energy from the concessionaire has a higher value you can take advantage of the spare energy in the battery of the electric vehicle, respecting the limits of preservation of its useful life. In view of this, we intend to seek an answer that will reduce the consumption impacts caused by the insertion of the new load into the network, resulting in a reformulation of the residential consumption curve. Counting on distributed generation, we sought more effective demand responses, reducing the energy consumption of the grid when using compensation generation.
