(Operation of this embodiment)
FIG. 5 is a flowchart showing the operation of the wide area power control server in this embodiment.
When the process is started, the wide area power control server 21 acquires the power usage status information 42 from the power information providing site 41 in step S10.

  In step S <b> 11, the wide area power control server 21 determines whether or not there is a target user based on the user registration information 22. The wide area power control server 21 performs the process of step S12 if the condition is satisfied (Yes), and returns to the process of step S10 if the condition is not satisfied (No).

In steps S12 to S22, the wide area power control server 21 repeats the process for all target users. Hereinafter, the target user being processed is referred to as “the user”.
In step S <b> 13, the wide area power control server 21 selects the control according to the power usage status information 42 based on the information of the user registration information 22 of the user.

In step S14, the wide area power control server 21 determines whether or not the selected control is for controlling the home gateway 31 of the user. That is, it is determined whether or not any one of the electric devices 34 connected to the home gateway 31 is controlled. For example, the wide area power control server 21 does not control the home gateway 31 if the power usage rate is less than 85% regardless of which of the menu A to the menu D is selected in the control policy menu 23 of the home gateway 31. Judge.
The wide area power control server 21 performs the process of step S15 if the condition is satisfied (Yes), and performs the process of step S22 if the condition is not satisfied (No).
In step S15, the wide area power control server 21 instructs the home gateway 31 of the user to execute the registered control contents. That is, the wide area power control server 21 gives a control instruction to the home gateway 31 based on the information stored in the control policy column 22 d of the user registration information 22 and the control policy menu 23.
In step S <b> 16, the wide area power control server 21 receives the control result from the home gateway 31 of the user. The control result is a response to the control instruction.

In step S <b> 17, the wide area power control server 21 refers to the control policy column 22 d of the user registration information 22 of the user and determines whether or not it is a target for service settlement. In the present embodiment, when the control policy column 22d is “electricity is low but the power usage rate is high when the power usage rate is high”, it is assumed that the service is to be settled. Here, service settlement refers to a settlement process in which the electricity bill is reduced by a predetermined value if the power consumption is suppressed when the power usage rate is high. The wide area power control server 21 performs the process of step S18 if the condition is satisfied (Yes), and performs the process of step S22 if the condition is not satisfied (No).
In step S18, the wide area power control server 21 instructs the home gateway 31 of the user to collate the control result prediction with each device and meter (wattmeter 33). Here, the control result prediction refers to information in the power consumption column 32 f (FIG. 3) in which the device information 32 is reduced. Checking each device and meter (wattmeter 33) means checking the value of the reduced power consumption column 32f (FIG. 3) and the value of power consumption measured by each electric device 34, and / or This means that the integrated value in the reduced power consumption column 32f (FIG. 3) is collated with the power consumption value measured by the meter (wattmeter 33).
In step S19, the wide area power control server 21 receives the collation result from the home gateway 31 of the user.

  In step S20, the wide area power control server 21 determines whether or not the collation result is correct. That is, the wide area power control server 21 determines whether or not power saving is correctly performed. The wide area power control server 21 performs the process of step S21 if the condition is satisfied (Yes), and returns to the process of step S15 if the condition is not satisfied (No).

  In step S <b> 21, the wide area power control server 21 notifies the electricity rate server 50 of the verification result. By this notification, the electricity bill server 50 can know that the user has implemented power saving, so that the electricity bill for the user who has contracted for service settlement can be reduced.

  In step S22, the wide area power control server 21 determines whether or not the process has been repeated for all target users. If the condition is satisfied, the wide area power control server 21 returns to the process of step S10 and repeats the process of FIG.

<< Instruction content = Control instruction >>
In step S <b> 32, the home gateway 31 determines whether or not an instruction content for notifying an alarm is included. The home gateway 31 performs the process of step S33 if the determination condition is satisfied (Yes), and performs the process of step S34 if the determination condition is not satisfied (No).
In step S33, the home gateway 31 notifies an alarm.

In step S34, the home gateway 31 performs processing according to the device control method. If the device control method is “entertainment device priority”, the home gateway 31 performs step S35. If the device control method is “power consumption priority”, the home gateway 31 performs step S36, and the device control method is “user”. If “designated”, the process of step S37 is performed.
In step S35, the home gateway 31 preferentially controls the entertainment device to the power saving mode (including power-off). That is, when the power usage rate exceeds 90%, the home gateway 31 preferentially controls the entertainment device to the power saving mode, and when the power usage rate exceeds 95%, further controls the daily necessities devices to the power saving mode. The home gateway 31 performs the process of step S38 when the process of step S35 is completed.
In step S36, the home gateway 31 preferentially controls a device that consumes a large amount of power to be reduced to a power saving mode (including power-off). That is, the home gateway 31 preferentially controls the electric device 34 that consumes a large amount of power to be reduced when the power usage rate exceeds 90%, and controls the power saving mode. The electric device 34 is controlled to the power saving mode. The home gateway 31 performs the process of step S38 when the process of step S36 is completed.
In step S <b> 37, the home gateway 31 controls each device in the power saving mode (including power-off) with the priority based on the designation by the user. That is, when the power usage rate exceeds 90%, the home gateway 31 preferentially controls the electric device 34 specified by the user to the power saving mode, and when the power usage rate exceeds 95%, the home gateway 31 further controls the other electrical devices 34. To power saving mode.
In step S38, the home gateway 31 notifies the wide area power control server 21 of the result of device control, and returns to the process of step S30. Here, the result of the device control is a response to the control command transmitted to each electric device 34.

<Instruction content = Control result verification>
In step S39, the home gateway 31 acquires the amount of power from each device and meter (wattmeter 33).
In step S40, the home gateway 31 collates the power amount with the power prediction of the device control result. Here, the power prediction of the device control result is based on the value of the reduced power consumption column 32 f (FIG. 3) of the device information 32.
In step S41, the home gateway 31 notifies the collation result to the wide area power control server 21, and returns to the process of step S30.
