“…Several papers propose optimization-based approaches to coordinate EV charging schedules with renewable energy generation and distribution network load demand. These approaches consider uncertainties related to renewable energy sources and EV charging demands in order to achieve load balancing and minimize network congestion [12,15,20]. Simulation-based studies utilizing software tools such as Power Factory are also common, enabling the assessment of the impact of EV charging on the distribution system.…”

Electric vehicles (EVs) have gained significant popularity, leading to concerns about their impact on distribution networks and the integration of renewable energy sources.In response, researchers have proposed various strategies and methodologies. These include adaptive charging coordination strategies that aim to minimize the influence of EV chargingon distribution networks while considering uncertainties in renewable energy generation and charging demands. Optimizationbased approaches have been employed to balance loads, alleviate network congestion, and coordinate EV charging schedules with renewable energy generation and distribution network demand. The studies have also highlighted potential issues such as distribution system overloading, voltage stability problems, and the need to account for different charging infrastructure scenarios and standards. To address these challenges, control strategies integrating EV charging and battery energy storage systems (BESS) have been proposed. These strategies aim to reduce peak power demands, optimize the utilization of renewable energy sources, and shift charging loads away from peak periods. How- ever, there are still gaps to be addressed, including scalability forlarge-scale deployment, user convenience, and economic viability.Further research is needed to explore these areas and consider the impact of user behavior, smart grid technologies, and cost- effectiveness in accommodating EV charging and plug-in hybrid electric vehicles (PHEVs) in residential distribution grids

“…Also, the battery life ends if its capacity goes down by 20% wrt its basic normal capacity. So, by adopting smart coordinated charging/discharging battery strategy, the electricity burden on generation side can be reduced during peak load hours (12). This EMS helps in SG supervision and has potential to maintain the proper energy flow to and from the EV batteries by deciding that, which EV battery will receive or send the power to the grid (13).…”

The Smart Grid is a unique manner, needs close collaboration between production, transmission and distribution systems. Earlier greenhouse gases result more sustainable energy systems, which involves solar and wind energy integration into distributed power systems. These renewables make this system further effective, where the new "Smart Grid" idea appears, which offers a two-way communication between the source and load with good power quality throughout the generation. Being reliability a challenge, storage options available but consumes electricity and create significant costs, so electric vehicles with a two-way power transferability (G2V and V2G), as temporary power storage device an alternative. This paper focuses on problems: unloading of grid, vehicles short average life, less vehicles participation rate and to make more durable the entire system. Previously different techniques are implemented but this proposal includes Energy Management System to integrate EV’s with grid to increase power utility according to load demand at different conditions.

“…Dentre osíndices de qualidade de energia estabelecidos pela ANEEL, a subtensãoé um dosíndices que pode ser muito afetado com a penetração em massa de veículos elétricos. Algumas estratégias poderiam ser adotadas pelas concessionárias, como o uso de tarifas horárias para que as curvas de carga dos EVs fossem deslocadas para horários fora da curva de demanda residencial de pico, comoé demonstrado por vários autores (Panichtanakom et al, 2018;Rawat and Niazi, 2018;Yan et al, 2014;Gao et al, 2013). Estratégias de tarifas horárias podem ser muitoúteis para diminuir as demandas de pico e com isso reduzir os esforços da rede, mas se tratando de níveis de tensão a tarefa nãoé tão simples, visto neste trabalho que mesmo a inserção de veículos recargando em potência reduzida podem causar problemas de subtensão que ultrapassariam os limites ideais do PRO-DIST (ANEEL, 2018), além de exigir investimentos em infraestrutura por parte das concessionárias para que esse sistema fosse estabelecido.…”

Veículos elétricos são promissores para a expansão das tecnologias verdes, sendo mais eficientes e menos poluentes que os atuais veículos a combustão. Alguns problemas relacionados uma maior densidade de energia das baterias ainda persistem, mas em um futuro próximo essa tecnologia se tornará viável e competitiva. Sabendo dessa expansão da frota de veículos elétricos, seus impactos devem ser estudados e normativas adequadas devem existir para que a tecnologia prevaleça com o mínimo de impacto ao atual sistema elétrico. Dentre os impactos mais observados estão o aumento na demanda que uma frota de veículos elétricos poderia causar no sistema elétrico de distribuição. Por outro lado, este trabalho busca avaliar os impactos em redes de distribuição secundária (baixa tensão). A partir de um modelo de rede, foram simulados casos de inserção de veículos elétricos em diferentes modos de carga, constatando-se que o aumento da demanda é inevitável, somado a altos picos durante momentos que normalmente o sistema já enfrenta. Em relação aos níveis de tensão, observou-se que os veículos elétricos podem causar subtensões que violam os limites estabelecidos pelo PRODIST, impacto que permanecerá se não forem estabelecidos parâmetros específicos nas normas brasileiras de veículos elétricos, essas baseadas na IEC.
