A Novel ICT Solution for Electric Vehicles Integration on Smart Grids

The integration of electric vehicles in smart grids introduces challenges due to the high involved power values and the vehicles mobility beyond the reach of the home area network. This paper presents a new ICT architecture that supports an energy management algorithm aiming to optimize the electric vehicle charging and storage capabilities accordingly with economical and technical considerations. The developed solution monitors the batteries' state of charge, state of health and available energy stored in the batteries, along the electric vehicle journey. The collected electric vehicle information is thereafter sent to databases in real-time base to achieve this mentioned purpose. The recorded data is accessible to the home area network aggregator and end user energy scheduler, and by other grid operator applications. According with the battery pack state of charge, the energy selling price and the custom energy usage profile is also possible, in some conditions, to apply the vehicle to grid concept. The energy management algorithm uses dynamic tariffs, end-users' preferences and comfort requirements regarding the operation of the remaining house appliances and electric loads.
