Shami and Dr. Khawar Siddique KhokharThe deployment of Electric Vehicles (EVs) has been proved as a very attractive option due to a great feasibility in transportation cost, reduction in carbon emission, and decrease in fuel dependency. However, this deployment threatens power grid operations due to varying temporal and spatial patternsof EVs' demand. Hence, for mainstream success, the capability to handle the potential extra load has become a major factor for power grid. For this integration it is necessary that the consumers and the power grid should coordinate with each other in harmony. Vehicle-to-Grid (V2G) technology can be used for this purpose by interconnecting Electric Vehicles with the power grid by either level peak demands or by strangling their charging rate. One of the key elements in V2G architecture is Aggregator. This entity plays a very crucial role to provide an interface between a large group of EVs and the power grid. Thus, there is a need of two established wireless communication links in a V2G system, the first is the communication link between the control center and the Aggregator, and the other one is the communication link between the Aggregator and the Electric Vehicles of its assigned area. This thesis aims to provide an investigative evaluation of the best suitable wireless access technology on the link between Aggregator and Electric Vehicles. For this purpose detailed communication architecture of V2G system has been explored to understand the exact role of Aggregator and its relationship with Electric Vehicle. Also the candidate wireless access technologies have been surveyed that can be employed in V2G communication system. Then mobile WiMAX has been selected for performance evaluation on the communication link between Aggregator and Electric Vehiclesin a multipath mobile fading environment. Itis a 4G technology that provides an infrastructure of wireless transmission that allows low maintenance costs as well as fast deployment. Physical layer of mobile WiMAX was simulated in MATLABSimulink, under considerations of Aggregator-to-Vehicle (A2V) communication channel. Due to the time-variant nature of the channel, all possible circumstances against the worst scenarios are tested to quantify the system's performance. The results obtained from the simulator were satisfactory and show that the mobile WiMAX is a suitable wireless technology that can provide a cost effective broadband internet access solution for A2V link. This research work is an original contribution to the available literature and will prove helpful in implementation of the system to turn the concept into the reality, which points out a possible solution for cost-effective and robust communication between Aggregator and Electrical Vehicle.enElectric VehiclesVehicle-to-Grid (V2G) technologyMS thesisThesis
