A power management approach for load leveling

Electrical generating utilities are increasingly annoyed with the growing gap between the peaks and valleys of electricity demand. This paper proposes a power management approach for load leveling by utilizing battery-equipped devices. This approach implements a peak-shift on devices which include a built-in battery. Performing a peak-shift on such devices narrows the gap. In addition, it also helps reduce CO/sub 2/ emissions. This approach can be implemented on widely used notebook computers. Although the size of the peak shift on each device is small, by combining large numbers of devices, it is possible to show large effects.
