Smart management of PHEV and renewable energy sources for grid peak demand energy supply

Electric Vehicles (EV) have become popular due to increasing oil prices and environmental issues. Vehicle-to-Grid (V2G) system allows bidirectional electricity flow from vehicle´s battery to power grid. In this paper, Plug-in Hybrid Electric Vehicle (PHEV) has been considered as an option for energy storage in a smart system where renewable energy sources (RES) are included along with main grid. Smart charging system will ensure that an electric vehicle owner will charge the battery during off peak hours and discharge remaining energy back to the grid during peak demand hours. Development of such charging station in a smart grid network is capable of solving the problem of peak demand crisis. PHEV and grid energy management model has been analyzed using HOMER. A Graphical User Interface (GUI) is built where an electric vehicle owner will get the precise time period for charging and discharging their vehicles and the cost of energy through smart metering.
