Análise da penetração dos veículos elétricos no sistema de distribuição considerando curvas de carga de consumidores residenciais

Abstract

Recent researches shows that the Electric Vehicle (EV) market is expected to grow a lot in the coming years. EVs are a way of offering consumers greater savings and less pollution, reducing the rate of gas emissions. The EV is not exclusively a question of sustainability. Comparing the cost of mait aing na EV, economy is also very relevant. Thus, it is known that EVs need electricity to recharge their batteries. This energy is provided by the electric grid, and if there is a large number of EVs requesting a recharge at the same time, there may be an overload in the operation of the Electric distribution system. Thus, the present work aims to build residential load curves with the load increment caused by EV demand. This approach will take into account the LV power, frequency on which the vehicle will be charged, and the type of charging, thus determining the LV load curve aided by the Monte Carlo Method (MMC). With the residential and EV load curves, a new residential load curve will be generated. The penetration of EVs will also be assumed by the MMC, thus determining a new load curve typical for residential consumers with EVs. After carrying out the proposed methodology and studying the scenarios covered in the work, the coordinated recharge is concluded, avoiding a significant increase in demand during peak hours, and this increase can generate an overload in the electrical system. Regarding the observation of the typical load curve, it is concluded that this curve will depend on the tariffs that the consumer units are framed.
