<P>PROBLEM TO BE SOLVED: To provide a technology for sequentially correcting a daily load prediction curve in consideration of an influence brought by the amount of electric power generation of a dispersion type power source interconnected with a service wire. <P>SOLUTION: A rear load prediction curve is pregenerated. A passing current load is calculated on the basis of a passing current passing through a service wire. In addition, the amounts of reverse power flow energy of a plurality of dispersion type power sources are measured, and the total amounts of reverse power flow energy are calculated on the basis of a measured value of the amount of reverse power flow energy. The total maximum possible amounts of power generation of the plurality of dispersion type power sources are precalculated. The prediction curve is corrected to satisfy a relationship in which a rear load obtained from the prediction curve becomes higher than the sum of the passing current load and the total amounts of the reverse power flow energy and lower than the sum of the passing current load and the total maximum possible amounts of power generation of the dispersion type power sources. <P>COPYRIGHT: (C)2013,JPO&INPIT |
