Abstract

A prediction value calculator calculates a prediction value of an electricity fee based on the amount of electric power supplied from a commercial electric power source to electric equipment within an electricity fee calculation period. A selector selects, as a first-stage control, either one control of an electric power saving control for the electric equipment and a charge-discharge control in which the electric power supplied from the commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which the unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot. A controller executes the first-stage control selected by the selector when the prediction value calculated by the prediction value calculator is greater than a targeted value of the electricity fee.

First claim

The invention claimed is:

1. A control device comprising:
a selector configured to select, as a first-stage control, either one control of an electric power saving control for electric equipment and a charge-discharge control in which electric power supplied from a commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which a unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot; and
a controller configured to, in a case in which a prediction value of an electricity fee is greater than a target value of an electricity fee, (i) execute the charge-discharge control when the charge-discharge control is selected as the first-stage control by the selector, and (ii) execute the electric power saving control when the electric power saving control is selected as the first-stage control by the selector.

2. The control device according to claim 1 , further comprising an acceptor configured to receive designation information designating either one control of the charge-discharge control and the electric power saving control,
wherein the selector is configured to select the charge-discharge control as the first-stage control when the charge-discharge control is designated by the designation information received by the acceptor, and to select the electric power saving control as the first-stage control when the electric power saving control is designated by the designation information.

3. A control device comprising:
a selector configured to select, as a first-stage control, either one control of an electric power saving control for electric equipment and a charge-discharge control in which electric power supplied from a commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which a unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot; and
a controller configured to execute the first-stage control selected by the selector, when a prediction value of an electricity fee is greater than a target value of an electricity fee,
wherein
the selector is further configured to select, as a second-stage control, an other control of the electric power saving control and the charge-discharge control, and
the controller is further configured to execute the first-stage control when the prediction value is greater than the target value and a difference between the prediction value and the target value is less than a first threshold, and to execute the second-stage control selected by the selector in addition to the first-stage control when the prediction value is greater than the target value and the difference is greater than the first threshold.

4. A control device comprising:
a selector configured to select, as a first-stage control, either one control of an electric power saving control for electric equipment and a charge-discharge control in which electric power supplied from a commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which a unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot;
a controller configured to execute the first-stage control selected by the selector, when a prediction value of an electricity fee is greater than a target value of an electricity fee; and
a ratio calculator configured to calculate a ratio of an amount of electric power supplied from the commercial electric power source to the electric equipment in the second time slot among the amount of electric power supplied from the commercial electric power source to the electric equipment,
wherein the selector is configured to select the charge-discharge control as the first-stage control when the ratio calculated by the ratio calculator is greater than a second threshold, and to select the electric power saving control as the first-stage control when the ratio is less than the second threshold.

5. A control device comprising:
a selector configured to select, as a first-stage control, either one control of an electric power saving control for electric equipment and a charge-discharge control in which electric power supplied from a commercial electric power source is stored in a storage battery mounted on an electric vehicle in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which a unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot;
a controller configured to execute the first-stage control selected by the selector, when a prediction value of an electricity fee is greater than a target value of an electricity fee; and
an acquirer configured to acquire schedule information indicating a schedule of the electric vehicle,
wherein
the selector is configured to select the charge-discharge control as the first-stage control when the storage battery is indicated to be available by the schedule information acquired by the acquirer, and to select the electric power saving control as the first-stage control when the storage battery is indicated to be not available by the schedule information acquired by the acquirer.

6. A control device comprising:
a controller configured to,
when a prediction value of an electricity fee is greater than a target value of an electricity fee and a difference between the prediction value and the target value is less than a first threshold, execute either one control of an electric power saving control for electric equipment and a charge-discharge control in which electric power supplied from a commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which a unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot, and
when the prediction value is greater than the target value and the difference is greater than the first threshold, execute the electric power saving control and the charge-discharge control.

7. A control system comprising:
a measurer configured to measure an amount of electric power supplied from a commercial electric power source to electric equipment;
a selector configured to select, as a first-stage control, either one control of an electric power saving control for the electric equipment and a charge-discharge control in which the electric power supplied from the commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which a unit cost of the electric power from the commercial electric power source is greater than that in the first time slot; and
a controller configured to, in a case in which a prediction value of an electricity fee based on the amount of electric power measured by the measurer is greater than a target value of an electricity fee, (i) execute the charge-discharge control when the charge-discharge control is selected as the first-stage control by the selector, and (ii) execute the electric power saving control when the electric power saving control is selected as the first-stage control by the select
