The roll-up roll-away Tactical Vehicle-to-Grid / Vehicle-to-Vehicle (V2G/V2V) system provides a plug-and-play, very fast forming, smart, aggregated, and efficient power system for an emerging (including austere) contingency base. The V2G/V2V system gives the Soldier a capability they currently lack: The ability to generate up to 240kW of 120/208 VAC 3-phase power anywhere, anytime using Transmission-Integrated Generators (TIGs) to produce 600VDC for use by vehicle hotel loads (electrification), transfer of power from V2V, and export power off-vehicle in a Forward Operating Base (FOB) environment, V2G. The system is designed to provide grid services (peak shaving, Volt/VAR control, power regulation, and current source mode) beneficial to emerging and mature grids (CONUS or OCONUS). Data collected during the FY 14 Tactical Enabled Contingency Basing Demonstration (TECD 4a) of a single vehicle with V2G capability showed that variable speed engine power management can provide up to 50 percent fuel reduction. This multivehicle based power system utilizes variable engine speeds for efficient power generation. The demonstration project includes the sub-system development, communications systems development, system integration, testing, and demonstration. The system supports host-grid connectivity to reduce deployed fuel consumption for power generation by 20 percent. The system capability will be first demonstrated at TARDEC and then with the Warfighter at Fort Devens, Sustainability Logistics Basing (SLB) Science and Technology Objective Demonstration (STO/D), in FY16.
