“…In the Brazilian market, the low EV penetration, if compared to the main global markets, is due to both the high prices of EVs and the reduced number of specific public policies to encourage EV sales in the country [55]. National plans and programs related to the theme have been implemented, but without setting specific goals and objectives for electric mobility [56].…”

The global fleet of electric vehicles (EV) has been rising in recent years, and public policies can play an important role in this scene. The objective of this work is to evaluate the impact of public policies in the diffusion of EVs in Brazil, based on Beck’s adaptation for the Bass diffusion model. This modification on the Bass model allows the estimation of EV diffusion, taking into account the direct and indirect economic influence of the main EV incentive instruments used worldwide. In addition, this work conducts a forecast of the total passenger cars in Brazil through a regression model, considering macroeconomic and social indicators. The results indicate that EV high prices may still be the major barrier for EV diffusion in Brazil over the studied horizon, keeping them inaccessible to the majority of the population. Therefore, policies aimed at subsidizing EVs may be more effective in stimulating EV sales.

“…Electrification of road transport, particularly personal vehicle utilization, has been identified as an important means to address the global challenge of reducing carbon emissions [1]. The growth of the EV market share has stimulated extensive research in the analysis of the impact of uncontrolled charging on both low [2,3] and medium voltage [4,5] PDNs. Works include the impact analysis for different grid topologies, e.g., rural, suburban or urban PDNs [6,7], for different countries [2,[8][9][10] or commonly used test systems [11][12][13] due to a lack of data.…”

The uptake of electric vehicles (EVs) may pose a challenge to power distribution networks (PDNs). While smart charging can be deployed to relieve stress on the grid, user-centric smart charging strategies could also exacerbate peak power demand due to synchronization when optimizing charging with regard to different objectives, such as charging costs. In this paper, we assess the charging demand emerging from a large fleet of EVs, with models for the decision to charge and distribution of the steady-state state-of-charge (SoC). These are applied to the municipality of Frederiksberg, Denmark, using data from the Danish national travel survey. Home and workplace charging are mapped to the urban 10 kV medium voltage PDN of Frederiksberg considering different charging behaviors and degrees of synchronization. Results indicate that the likelihood of severe congestion in the power distribution network is low and that it can be attributed to rare scenarios in which high synchronization is observed, particularly when maintaining the normal steady-state demand. Despite the low likelihood, preventive measures should be devised to mitigate such scenarios, especially if additional high-power consumers are connected.

“…Como exemplo, no trabalho de Clement-Nyns, Haesen e Driesen (2011) um algoritmo desenvolvido utilizando PL conseguiu resolver grande parte dos problemas de subtensão ocasionados pela recarga descoordenada de VEs. Similarmente, Bitencourt et al (2019), utilizando do mesmo algoritmo, foi capaz de analisar os impactos que a carga extra advinda da recarga de VEs ocasiona nos transformadores. Um outro método, desta vez desenvolvido por Affonso e Kezunovic (2019), conseguiu evitar a sobrecarga nos transformadores e consequente redução da vida útil do transformador, através da recarga coordenada de VEs e de um sistema de baterias na presença de geração fotovoltaica.…”

This paper proposes a smart charging method using linear programming to minimize the EVs charging costs and attend transformer capacity constraint, reducing the negative impacts of uncoordinated charging, bringing benefits for both utility and consumer. Simulations are conducted through OpenDSS software in a real distribution system in Brazil. Several penetration levels and different electricity tariffs are considered. The results show smart charging can efficiently reduce energy costs and mitigate some negative effects of uncoordinated charging, even for high penetration levels of electric vehicles.Resumo: Este artigo propõe um método de recarga inteligente utilizando programação linear, visando reduzir os custos de energia e atender as restrições de limite de capacidade do transformador, mitigando os impactos negativos da recarga descoordenada, trazendo benefícios tanto a concessionária de energia quanto ao consumidor. As simulações são realizadas através do software OpenDSS em uma rede de distribuição real do Brasil. São considerados vários níveis de penetração e diferentes modelos tarifários para avaliação do desempenho da metodologia proposta. Os resultados mostram que a recarga inteligente consegue de forma eficiente reduzir os custos de energia e ainda mitigar de forma satisfatória os efeitos negativos da recarga descoordenada, mesmo para altos níveis de penetração de veículos elétricos.
