Sistema inteligente para o controle da recarga de veículos elétricos híbridos plug-in visando o benefício do sistema elétrico de potência

Abstract

Plug-in hybrid electric vehicles (PHEV) are seen as an important alternative to reduce pollutant emissions into the atmosphere. These vehicles need to be connected to the power grid to recharge their batteries. Thus, if a considerable amount of PHEVs request charge simultaneously and without proper coordination, problems in the power system operation may arise. Therefore, it is important to carry out a coordinated charging control of electric vehicles. The PHEVs can also aid the power grid by controlling the charging rate and injecting active power. Given so, this work proposes a system for the charging control of plug-in hybrid electric vehicles seeking the power grid and consumer benefits. In this work, a strategy to control the charging and an optimisation technique will be applied using a distribution system simulation software and a programming environment. With the developed system it is expected to mitigate the impact on the power grid and optimize its operation, benefiting the local utility, the electrical grid and the consumer.
