A novel vehicle to grid load management scheme based on WiMAX-WLAN in smart grids

Challenges associated with Vehicle to Grid (V2G) power transmission in Smart Grids include dealing with a large number of Plug-in Electric Vehicles (PEVs) and establishment of a robust and reliable communication network for short burst transmissions. This paper proposes an end-to-end load management scheme to enable V2G power transmission based on a WiMAX WLAN hybrid network architecture in Smart Grids and considers the case of peak power via discharging PEVs with small energy bursts while WiMAX-WLAN network efficiently deals with flexible data aggregation to reduce signaling and protocol overheads. A novel energy scheduling algorithm is presented for an efficient admission control process and to deal with variable energy budgeting within a specific timeframe. A wide area heterogeneous network based on WiMAX and WLAN was modelled to examine the performance of the energy scheduling algorithm and the communications network for large-scale V2G power management. Results presented show that the proposed scheme can successfully manage the V2G power supply with a very low signaling overhead.
