  • ORDER ASSISTANCE APPARATUS, SYSTEM, AND METHOD, AND COMPUTER-READABLE MEDIUM
    Publication number: 20240086039
    Abstract: An order assistance apparatus includes: a display control unit configured to display sales information that has accepted the selecting operation with an addition of the number of orders corresponding to the number of times of the selecting operations in question; and a determination unit configured to determine whether or not the number of orders in question is equal to or greater than an upper limit value, in which when the number of orders is smaller than the upper limit value, the display control unit updates a display of the number of orders added to the sales information that has accepted a selecting operation by a value obtained by adding a number corresponding to the single selecting operation to the number of orders in question, and clears the number of orders in question when the number of orders is equal to or greater than the upper limit value.

  • Supply and demand control apparatus for electric power system, and storage medium storing supply and demand control program
    Patent number: 8536835
    Abstract: According to one embodiment, the economical load dispatcher calculates a discharging threshold value and a charging threshold value based on a discharging unit price of and a charging and discharging efficiency of the secondary battery and further calculates output allocations of the generators and secondary battery such that the secondary battery is discharged when incremental fuel costs of the generators are higher than the discharging threshold value, whereas the secondary battery is charged when incremental fuel costs of the generators are lower than the charging threshold value.
