POWER DEMAND ESTIMATING APPARATUS, METHOD, PROGRAM, AND DEMAND SUPPRESSING SCHEDULE PLANNING APPARATUS
First Claim
1. A power demand estimating apparatus that estimates a power demand on a designated estimation day, the apparatus comprising:
- a demand data memory storing;
a plurality of power demand patterns which are classified in accordance with an environmental condition, and which show a power demand rate per a unit time; and
power demand amount data per temperature gathering up a maximum value and a minimum value of a power demand amount at each temperature;
a demand estimator selecting the demand pattern that matches the environmental condition on the estimation day from the demand data memory, obtaining the maximum value and the minimum value of the power demand amount at an expected temperature on the estimation day from the power demand amount data per temperature, calculating the power demand amount per a unit time on the estimation day, and creating a demand estimating model on the estimation day; and
a display displaying the demand estimating model on the estimation day together with the power demand pattern selected by the demand estimator.

Abstract
A power demand estimating apparatus includes a demand data memory, a demand estimator, and a display. The demand data memory stores plural power demand patterns and power demand amount data. The demand estimator selects, from the demand data memory, the demand pattern matching the environmental condition on an estimation day, obtains the maximum value of an power demand amount and the minimum value thereof at an expected temperature on the estimation day, calculates, using those pieces of information, the power demand amount per a unit time on the estimation day, and creates a demand estimating model. The display displays, together with the power demand pattern selected by the demand estimator, the demand estimating model.
