Impact of EV charging station on the electric distribution grid

ABSTRACT Over the past few years, Electric vehicles have become a very important part of the automotive industry as we try to look for a future less dependent on fossil fuels. A lot of research and development has taken place in this field to improve the existing technology and to develop efficient ones. This continued emphasis on research and development has resulted in great improvements in the technology of Electric vehicles. In this thesis, we discuss about the features of Electric Vehicles, the existing protocols to charge the battery systems, the battery management system (BMS), the different standards used in various parts of the world and about the infrastructure that is needed to charge the Electric Vehicles and about the different modes of charging. In the next part of the thesis, we have focussed on the Electric Vehicle and its relationship with the Electric Distribution Grid. Aspects related to PHEV characteristics, Load growth, PHEV Penetration level are looked into. The essence of this thesis is to learn about the Impact of the EV Charging Station on the Electric Distribution Grid. Research papers regarding the impact study of EV Charging station on the Milan Electric Distribution network is considered and discussed. Finally, we look at the Optimisation of EV charging stations which helps in the overall efficiency of the charging process and lessens its impact on the Electric Distribution Grid. In this study we discuss about various control strategies of battery management, charging and the control of inverters.
