Abstract

A system and method are provided for managing demand for a client with a fluctuating AC power grid demand, using DC-to-AC power inversion as an auxiliary source of power. The inverter has a selectable inversion power output levels connected to the AC client to supply auxiliary power for a portion of the AC power demand. The AC grid demand is averaged. In each of a series of periodic time intervals, a current AC grid demand average in a current time interval is compared to a demand goal, which is the highest AC grid demand average, as measured at an end of a time interval, and selected from a plurality of time intervals. The inverter output power level is selected so that the current AC grid demand average is less than or equal to the demand goal by the end of the current time interval.
