Abstract

A device control apparatus performs demand response control in which an amount of energy consumed in a predetermined time slot by a facility device is adjusted in accordance with an adjustment request. The device control apparatus includes a reception unit that accepts an operation instruction for the facility device, an expense effect presentation unit and a comfort effect projection. The expense effect presentation unit presents an expense effect incurred on a charge in association with the amount of energy consumed by the facility device through an activity based on the operation instruction. The comfort effect projection unit projects an effect on comfort incurred in a space surrounding the facility device in association with the amount of energy consumed by the facility device through the activity based on the operation instruction.

Claims

1. A device control apparatus configured to perform demand response control in which an amount of energy consumed in a predetermined time slot by a facility device is adjusted in accordance with an adjustment request, the device control apparatus comprising:

a reception unit configured to accept an operation instruction for the facility device; and

a control unit including a CPU programmed to serve as

an expense effect presentation unit configured to present an expense effect incurred on a charge in association with the amount of energy consumed by the facility device through an activity based on the operation instruction, the facility device being adjusted by the demand response control in the predetermined time slot, and

a comfort effect projection unit configured to project an effect on comfort incurred in a space surrounding the facility device in association with the amount of energy consumed by the facility device through the activity based on the operation instruction, the facility device being adjusted by the demand response control in the predetermined time slot,

the expense effect presentation unit being further configured to present the expense effect and the effect on comfort for each set of contents of the operation instruction accepted by the reception unit when the operation instruction comprises multiple types of contents, and

the comfort effect projection unit being further configured to project the effect on comfort by suppressing an output of the facility device, returning the output of the facility device to a state prior to the suppressing, and calculating a change in the space surrounding the facility device between the suppressing and the returning.

2. The device control apparatus according to claim 1, further comprising:

a receiving unit configured to receive charge computation information useable to compute a charge associated with the amount of energy consumed, the charge computation information being received from a host energy management apparatus that manages energy supplied to the facility device,

the CPU being further programmed to serve as a computation unit configured

to estimate a power fluctuation amount caused by the activity based on the operation instruction for the facility device, and

to compute the expense effect to be presented by the expense effect presentation unit by applying the estimated power fluctuation amount to the charge computation information received by the receiving unit.

3. The device control apparatus according to claim 2, wherein

the receiving unit is further configured to receive incentive information from the host energy management apparatus, the incentive information being included in the charge computation information and pertaining to a reward for complying with a request associated with energy consumption from the host energy management apparatus, and

the expense effect presentation unit is further configured to present an incentive change as the expense effect, the incentive change being caused in association with the amount of energy consumed by the facility device.

4. The device control apparatus according to claim 3, wherein

the computation unit is further configured to calculate an incentive reduction amount based on the estimated power fluctuation amount, a remaining time in the time slot for which an adjustment of the amount of energy consumed is requested as indicated by the incentive information, and an incentive unit price indicated by the incentive information, and

the expense effect presentation unit is further configured to present an incentive reduction amount as the expense effect, the incentive reduction amount being calculated by the computation unit.

5. The device control apparatus according to claim 2, wherein

the receiving unit is further configured to receive penalty information from the host energy management apparatus, the penalty information being included in the charge computation information and pertaining to a penalty that increases the charge when a request associated with energy consumption from the host energy management apparatus is not satisfied, and

the expense effect presentation unit is further configured to present a penalty as the expense effect, the penalty being caused in association with the amount of energy consumed by the facility device.

6. The device control apparatus according to claim 5, wherein

the computation unit is further configured to calculate a penalty price based on the estimated power fluctuation amount, a remaining time in the time slot for which an adjustment of the amount of energy consumed is requested as indicated by the penalty information, and a penalty unit price indicated by the penalty information, and

the expense effect presentation unit is further configured to present a penalty price as the expense effect, the penalty price being calculated by the computation unit.

7. The device control apparatus according to claim 2, wherein

the computation unit is further configured to calculate a computation result of the expense effect using a numerical value, and

the expense effect presentation unit is further configured to present the expense effect calculated by the computation unit using the numerical value.

8. The device control apparatus according to claim 3, wherein

the expense effect presentation unit is further configured to present a display indicating that the expense effect will not be affected by at least one of the incentive change and the penalty when there is no occurrence of at least one of the incentive change and the penalty caused by the activity of the facility device based on the operation instruction.

9. The device control apparatus according to claim 1, further comprising:

a display unit configured to display an effect of device non-activity caused by a situation that the activity is not performed based on the operation instruction for the facility device.

10. The device control apparatus according to claim 9, wherein

the facility device is an air conditioner that performs temperature adjustment of indoor temperature, and

the display unit is further configured to display an effect on the indoor temperature caused by a situation that the temperature adjustment is not performed by the air conditioner.

11. The device control apparatus according to claim 1, wherein

the expense effect presentation unit is further configured to present the expense effect when the reception unit accepts the operation instruction as a trigger.

12. The device control apparatus according to claim 1, wherein

the expense effect presentation unit is further configured to present the expense effect before or after the activity based on the operation instruction.

13. The device control apparatus according to claim 1, wherein

the reception unit is further configured to accept a presentation instruction for the expense effect, and

the expense effect presentation unit is further configured to present the expense effect when the reception unit accepts the presentation instruction as a trigger.

14. The device control apparatus according to claim 1, further comprising:

an activity information storage unit configured to store an activity in association with the expense effect and time information when the activity has been performed based on the operation instruction; and

an activity extraction unit configured to extract the activity from the activity information storage unit, the activity having been performed in the time slot during which the adjustment of the amount of energy consumed is requested,

the expense effect presentation unit being further configured to present the expense effect for the activity extracted by the activity extraction unit.
