Abstract
An algorithm calculates a correction value to be applied to a slot in an adjustment period for power correction. For each slot, the algorithm determines whether adding a correction value in a given slot would bring the actual accumulative adjustment value closer or farther from a total desired power correction value for the adjustment period. In one embodiment, the correction value is added to consecutive slots in the adjustment period to conduct the correction as fast as possible. The algorithm also checks the total amount of adjustment applied to the slots over a sliding adjustment window within the adjustment period to make sure that the total amount of adjustment applied to the slots in the adjustment window do not exceed a predetermined maximum threshold.
