Abstract

A device operation setting apparatus includes a calculator and a determiner. The calculator calculates, based at least in part on a relationship between a setting value regarding operation control of a device and a consumed power of a device, a target value of the consumed power of the device. The determiner determines the setting value to cause that a difference between an actually measured consumed power of the device and the target value of the consumed power of the device calculated by the calculator is within a prescribed range.

Claims

1. A control system comprising:

a controller configured to determine a control value based on a setting value,

a device configured to execute a prescribed operation based on the control value,

a calculator configured to calculate a temporary consumed power value of the device, based at least in part on a relationship between a correction value and a consumed power value of the device, wherein the consumed power value is based on a temporary setting value,

the temporary setting value is the setting value used by the calculator to calculate a target value, based on the device model,

the temporary consumed power value is the consumed power value of the device for the case of operation in accordance with the temporary setting value, based on the device model,

the device model represents the relationship between the target value of the power of the device, which operates in accordance with the setting value, and that setting value,

a deterioration of the device is reflected in the device model,

wherein the correction value is calculated based on the setting value previously outputted to the controller for the device and an actually measured value of consumed power of the device; and

a determiner configured to adjust the temporary setting value to limit, within a prescribed range, a difference between a predetermined target value and the temporary consumed power value calculated by the calculator, and configured to determine the setting value for outputting to the controller,

wherein the setting value for outputting to the controller is equal to the temporary setting value adjusted.

2. The control system according to claim 1, wherein the determiner is configured to adjust the temporary setting value so that the temporary setting value is within a first range.

3. The control system according to claim 2, wherein the determiner is configured to adjust the temporary setting value so that the calculated temporary consumed power value is within a second range.

4. The control system according to claim 3, wherein the determiner is configured to determine whether or not, by changing the temporary setting value, it is possible to make the difference between the actually measured value of consumed power of the device and the calculated temporary consumed power value to be within the prescribed range and, if it is not possible to make the difference between the actually measured value and the calculated target value to be within the prescribed range, the determiner controls another device, to cause the difference to be within the prescribed range.

5. The control system according to claim 4, wherein the device is an electric freezer;

and

wherein the other device is a heat storage tank.

6. The control system according to claim 2, wherein the determiner is configured to determine whether or not, by changing the temporary setting value, it is possible to make the difference between the actually measured value of consumed power of the device and the calculated temporary consumed power value to be within the prescribed range and, if it is not possible to make the difference between the actually measured value and the calculated target value to be within the prescribed range, the determiner controls another device, to cause the difference to be within the prescribed range.

7. The control system according to claim 6, wherein the device is an electric freezer;

and

wherein the other device is a heat storage tank.

8. The control system according to claim 1, wherein the determiner is configured to determine whether or not, by changing the temporary setting value, it is possible to make the difference between the actually measured value of consumed power of the device and the calculated temporary consumed power value to be within the prescribed range and, if it is not possible to make the difference between the actually measured value and the calculated target value to be within the prescribed range, the determiner controls another device, to cause the difference to be within the prescribed range.

9. The control system according to claim 8, wherein the device is an electric freezer;

and

wherein the other device is a heat storage tank.

10. A non-transitory computer readable storage medium that stores a computer program to control a device, the program being to cause a computer to perform at least:

calculating a temporary consumed power value of the device, based at least in part on a relationship between a correction value and a consumed power value of the device,

wherein the consumed power value is based on a temporary setting value,

the temporary setting value is the setting value used by the calculator to calculate a target value, based on the device model,

the temporary consumed power value is the consumed power value of the device for the case of operation in accordance with the temporary setting value, based on the device model,

the device model represents the relationship between the target value of the power of the device, which operates in accordance with the setting value, and that setting value,

a deterioration of the device is reflected in the device model,

wherein the correction value is calculated based on a setting value previously outputted to a controller for the device and an actually measured value of consumed power of the device; and

adjusting the temporary setting value to limit, within a prescribed range, a difference between a predetermined target value and the temporary consumed power value calculated, and determining the setting value for outputting to the controller,

wherein the setting value for outputting to the controller is equal to the temporary setting value adjusted,

the controller configured to determine a control value based on the setting value,

the device configured to execute a prescribed operation based on the control value.

11. A control method comprising:

determining a control value based on a setting value,

executing a prescribed operation based on the control value,

calculating a temporary consumed power value of a device, based at least in part on a relationship between a correction value and a consumed power value of the device,

wherein the consumed power value is based on a temporary setting value,

the device model represents the relationship between the target value of the power of the device, which operates in accordance with the setting value, and that setting value,

a deterioration of the device is reflected in the device model,

wherein the correction value is calculated based on the setting value previously outputted to a controller for the device and an actually measured value of consumed power of the device; and

adjusting the temporary setting value to limit, within a prescribed range, a difference between a predetermined target value and the temporary consumed power value calculated, and determining the setting value for outputting to the controller,
