<P>PROBLEM TO BE SOLVED: To compute an amount of deviation between the power demanded and the power supplied, without installing an interval meter or the like at a customer, when the customer is connected and supplied with power, and monitor the amount of deviation between the power demanded and the power supplied in power management, based on the computed amount of deviation between the power demanded and the power supplied. <P>SOLUTION: Amount of deviation between the demanded power and the supplied power computating system comprises a supplied power computating portion 21 that computes power supplied per unit time, with respect to the power supplied from PPS to a power utility company; a demanded power computating portion 31 that computes the power demanded per unit time of a customer having contract with PPS; a demanded power and supplied power computating portion 32 that computes the amount of deviation between the demanded and supplied power, based on the difference between the power supplied per unit time and the total power demanded per unit time; and a billing portion 33 that makes a charge for excess electricity bill, based on the amount of deviation between the power demanded and the power supplied. The demanded power computating portion 31 uses a standard load curve that represents the estimated value of power per day, based on the power consumed by each customer per unit time and computes the power demanded per month for each customer. In addition, it monitors the amounts of deviation between the power demanded and the power supplied in power management based on the computed amounts of deviation between the power demanded and the power supplied. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
