Plug-in Electric Vehicle Connected to Nano-Grid without Storage System

Abstract

Vehicle-to-Grid (V2G) describes a system in which plug-in electric vehicles, such as Battery Electric Vehicles (BEV), Plug-in Hybrid Electric Vehicles (PHEV) communicate with the power grid to sell demand response services by either returning electricity to the grid or by throttling their discharging rate.V2G storage capabilities can also enable EVs to store and discharge electricity generated from renewable energy sources such as solar and wind. When the vehicles are parked in a parking-slot, the power can be sent from Vehicle to the DC bus-bar or to the grid. From each Electric-vehicle the voltage level and State of Charge (SOC) information is uploaded to the CLOUD on a regular basis. Fuzzy-Logic shall determine the participation factor/ranking of each vehicle and is communicated to the CLOUD. The Central Controller will receive the uploaded data and depending upon the load requirement the best vehicle(s), to be connected to the grid, is/are shortlisted. The selection information is then informed to the respective electric vehicle, through cloud, so that power is sent from V2G.
