Battery-powered, Electric-drive Vehicles Providing Buffer Storage for Pv Capacity Value

The use of batteries to provide storage for photovoltaic power has been evaluated in various contexts. In gridconnected applications, batteries can serve to provide firm peak-shaving for distributed PV installations. To date, however, the use of batteries from parked electricdrive vehicles (EDV) to provide buffer storage for PV capacity value has not been analyzed. The emerging vehicle to grid (V2G) concept suggests that batterypowered EDVs can provide power to the grid to serve various markets. This paper evaluates the use of battery-powered EDVs to provide buffer storage for grid-connected PV installations, assuming a V2G infrastructure. The approach could serve to provide capacity value for PV installations, thus enhancing their value as distributed demand-side resources.
