Abstract:
A computer system for determining a demand usage value at a predetermined time for a load powered by an electric power system, said demand usage value being determined over a time interval about equal to a predetermined count times a predetermined time interval, said computer system comprising:memory means for storing a plurality of values;means for acquiring a plurality of first values, which represent energy consumed from said electric power system by said load, and a plurality of second values, which correspond to the first values and which represent times at which the energy was consumed by said load;means for storing the first values and the second values in said memory means;means for retrieving said predetermined count plus one of pairs of the first values and the second values corresponding thereto from said memory means, with one of said second values corresponding thereto being about equal to said predetermined time;means for determining a first demand value from a pair of the first values and a pair of the second values corresponding thereto, and for determining at least one second demand value from at least another pair of the first values and at least another pair of the second values corresponding thereto; andmeans for averaging said first demand value with said at least one second demand value to determine said demand usage value.
