Abstract
A utility employs an active load management system (ALMS) to estimate available operating reserve for possible dispatch to the utility or another requesting entity (e.g., an independent system operator). According to one embodiment, the ALMS determines amounts of electric power stored in power storage devices, such as electric or hybrid electric vehicles, distributed throughout the utility's service area. The ALMS stores the stored power data in a repository. Responsive to receiving a request for operating reserve, the ALMS determines whether the stored power data alone or in combination with projected energy savings from a control event is sufficient to meet the operating reserve requirement. If so, the ALMS dispatches power from the power storage devices to the power grid to meet the operating reserve need. The need for operating reserve may also be communicated to mobile power storage devices to allow them to provide operating reserve as market conditions require.
