Vehicle-to-Grid (V2G) technology can be used to interconnect electric or plug in hybrid vehicles with the power grid by either delivering electricity and level peak demands or by throttling their charging rate. Two types of wireless communications are required to a V2G system. The communications between the Aggregator and the Control Center which will be realized through IEEE 802.16-2004 (802.16d) and between Aggregator and the Electric Vehicles which will be realized through vehicular communications (IEEE 802.11p). In this paper a V2G architecture design is presented and the two wireless communication protocols, are proposed and evaluated to the system needs. IEEE 802.16d referred to as Worldwide Interoperability for Microwave Access (WiMAX) specifies the air interface including the medium access control layer and multiple physical layer specifications of fixed broadband wireless access systems supporting multimedia services. IEEE 802.11p Wireless Access in Vehicular Environment defines modifications to IEEE 802.11 to support Intelligent Transportation Systems applications.
