Modeling and comprehensive analysis of WiMAX protocol for grid control center to aggregator communication in vehicle-to-grid (V2G)

Abstract

V2G has become a reality with development in power grid and advancements in vehicle technology. The electric vehicles (EV) will gradually replace the existing vehicles due to growing oil demand and environment concerns. The EVs can be integrated to the grid for power transaction and can contribute power to the grid. The Grid Control Center (GCC) to aggregator communication is very crucial in V2G operation in order to meet the load demand. The fixed WiMAX (Worldwide Interoperability for Microwave Access) protocol is proposed for GCC to aggregator communication. The applicable path loss models for WiMAX protocol are analysed and compared. The physical layer of WiMAX protocol is modeled in MATLAB/SIMULINK and its performance is investigated.
