Abstract

A system and method for managing the distributed generation of power from a plurality of vehicles is provided. In one embodiment, the method includes determining location information for the plurality of vehicles, determining that a demand for power in a first portion of the power grid has reached a power threshold, determining that the location information associated with a set of the plurality of vehicles satisfies a similarity threshold with the first portion of the power grid, and transmitting a request to a first group of vehicles in the set of vehicles to discharge power. In addition, the method may include receiving a response from at least some of the electric vehicles to which a request was transmitted, and determining whether to request the discharge of power from additional vehicles in the set of the plurality of vehicles based, at least in part, on the number of responses containing a confirmation of the discharge of power. The portion of the power grid may comprise a medium voltage power line or a substation.
