Abstract
A method and apparatus of obtaining a correction value for the deviation between an actual power usage and a desired target power usage during a time period, comprises dividing the time period into a plurality of time segments, measuring, after each time segment a fraction of time into each time period, and multiplying the fraction by the target power usage to obtain a value corresponding to the fraction of the total power usage during the cycle. Also after each time segment, the total amount of power which has actually been used is measured and a difference is taken between the total amount power used from the beginning of the period and the fraction of the target power usage from the beginning of the period. This value is then divided by the amount of time remaining in the cycle to obtain the correction value. The correction value can be processed and utilized to control an internal generator for the plant or to take other corrective action.
