The accuracy of the demand and supply result calculation and the required calculation time depend on how much the calculation time period is divided and the generator distribution calculation is performed with respect to the forecast total demand pattern shown in FIG. Decided. The dotted line in FIG. 9 is an example in the case of dividing into 24 hours a day, and the broken line is an example in the case of dividing into 8 hours in a day. Naturally, the accuracy in the 24-hour period is higher than that in the 8-hour period, but the calculation time is tripled. When this one day unit is repeatedly calculated for a week and a month, the calculation time required for one calculation becomes enormous. The conventional supply and demand result calculation device calculates according to a predetermined fixed calculation time zone. For example, 8 hours a day, 1 to 3 pm, 4

By determining the calculation time zone, it is possible to calculate in detail where the change in the forecast total demand is large, and to roughly calculate where there is little change, and it is possible to obtain the same accuracy as the conventional device in a short calculation time. Further, according to the demand and supply plan calculation apparatus of claim 2 of the present invention, the change of the forecast total demand is determined by determining the calculation time for the forecast total demand pattern with the specified allowable deviation number as a constraint condition. The large part can be calculated in detail, and the small change can be roughly calculated, and similar to [Claim 1], the same accuracy as the conventional device can be obtained in a short calculation time. Furthermore, according to the demand and supply plan calculation device concerning [Claim 3] of the present invention,
Is it the calculation time zone according to [Claim 1] and [Claim 2]?
Or, select a calculation time zone set by the operator and calculate the distribution of generators based on the selected calculation time zone. Therefore, it is possible to obtain the same accuracy as the conventional device.
