[Configuration of Power Control Device 1]
FIG. 2 is a diagram illustrating a configuration of the power control apparatus 1. The power control apparatus 1 includes a communication unit 11, a storage unit 12, and a control unit 13. The control unit 13 includes a demand amount specifying unit 131, a state specifying unit 132, and a main control unit 133.

  The communication unit 11 is a communication interface for communicating with the external server and the electric device 2. The communication unit 11 has a LAN (Local Area Network) controller for transmitting and receiving data via a network, for example.

  The storage unit 12 is a storage medium such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a hard disk. The storage unit 12 stores a program executed by the control unit 13. The storage unit 12 stores various data used by the control unit 13 to control the electric device 2.

  The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 functions as a demand amount specifying unit 131, a state specifying unit 132, and a main control unit 133 by executing a program stored in the storage unit 12.

  The demand amount specifying unit 131 determines the power demand amount based on the power generation amount data acquired from the server of the power generation company J1 via the communication unit 11 and the required power amount data acquired from the server of the power retailer J2. Identify. The demand amount specifying unit 131 may acquire the power generation amount data and the necessary power amount data in real time, or may periodically acquire the power generation amount data and the necessary power amount data. The demand amount specifying unit 131 notifies the main control unit 133 of the specified power demand amount.

  The state specifying unit 132 specifies the state of each of the plurality of electric devices 2 based on the state data indicating the state of the electric device 2 acquired from the electric device 2 via the communication unit 11.

The electric device 2 includes a function providing unit 21, a storage battery 22, and a power control circuit 23. The function providing unit 21 is a processing unit for the electric device 2 to provide various functions to the user, and includes a communication unit 211, a display unit 212, a storage unit 213, and a CPU 214. Details of the configuration and operation of the function providing unit 21 will be described later.

The power control circuit 23 is a circuit for controlling whether the power stored in the storage battery 22 is discharged to the commercial power network N or whether the power stored in the storage battery 22 is used for the operation of the function providing unit 21.

  FIG. 4 shows a state where the electric device 2 is connected to a power outlet and is supplied with power from the commercial power network N. The power control circuit 23 is a part of the power supplied from the commercial power network N based on the control of the determination unit 216 when the function providing unit 21 is operating while the electrical device 2 is connected to the power outlet.

It is also possible to control so that the electric power stored in is discharged to the commercial power network N.

[Configuration and operation of function providing unit 21]
Hereinafter, the details of the function providing unit 21 will be described with reference to FIGS. 3 to 6.
The communication unit 211 is a communication interface for communicating with other devices via a communication network. The communication unit 211 includes a wireless communication controller for transmitting and receiving data via a wireless communication network, for example.
The display unit 212 is a display for displaying various types of information.

  The storage unit 213 is a storage medium such as a ROM, a RAM, and a hard disk. The storage unit 213 stores a program executed by the CPU 214. The storage unit 213 stores various data used by the CPU 214 to charge or discharge the storage battery 22.

The CPU 214 functions as a state specifying unit 215, a determination unit 216, and a display control unit 217 by executing a program stored in the storage unit 213.
The state specifying unit 215 specifies the state of the electrical device 2. For example, the state specifying unit 215 specifies the state of the electrical device 2 in response to receiving the discharge request information requesting the discharge from the power control device 1 to the commercial power network N. The state specifying unit 215 specifies, as the state of the electrical device 2, for example, which function is being executed among a plurality of functions that can be executed by the electrical device 2. The state specifying unit 215 may specify the power consumption of the electric device 2 as the state of the electric device 2.

  The determining unit 216 determines whether or not to discharge the stored power to the commercial power network N based on the state specified by the state specifying unit 215. Even if the electric device 2 is operated by the power supplied from the commercial power network N, there is a possibility that the electric device 2 may be switched to a mode operated by the stored power of the storage battery 22 when a power failure occurs or the outlet is disconnected. Therefore, when the electrical device 2 is in a state of consuming a predetermined amount of power or more, the determination unit 216 functions using the stored power even when the power supplied from the commercial power network N cannot be used. Priority is given to allowing the operation of the providing unit 21 to continue, and the stored power is not discharged to the commercial power network N. On the other hand, when the electrical device 2 is not consuming a predetermined amount of power or more, the determination unit 216 discharges at least a part of the stored power to the commercial power network N, so that the stored power is stored in the electrical device 2. Make effective use of other devices.

  Further, the determination unit 216 may determine whether or not to operate the electric device 2 using the stored power based on the state specified by the state specifying unit 215. For example, the determination unit 216 starts the operation of the electric device 2 using the stored power or sends the stored power to the commercial power network based on whether or not the electric device 2 is in use when the discharge request information is received. It is determined whether or not to discharge. For example, the determination unit 216 discharges the stored power to the commercial power network N when the electrical device 2 is not used at the time when the discharge request information is received from the power control device 1 and does not consume more power than a predetermined value. Let On the other hand, when the electric device 2 is used at the time when the discharge request information is received from the power control device 1, the determination unit 216 does not discharge the stored power to the commercial power network N and uses it in the function providing unit 21. Control. By doing in this way, since the electric equipment 2 can avoid receiving electric power supply from the commercial power network N, discharging stored electric power to the commercial power network N, the utilization efficiency of electric power can be improved.

  The determination unit 216 is in a state in which the electric device 2 should be operated using the stored power based on the usage content of the electric device 2 at the time when the discharge request information is received, or in which the stored power should be discharged to the commercial power network N You may determine whether it is. The determination unit 216 determines, for example, that the electric device 2 is operated using the stored power when the power consumption in the electric device 2 at the time of receiving the discharge request information is equal to or greater than a threshold value. In addition, the determination unit 216 determines that the commercial power network N is to be discharged when the power consumption in the electric device 2 at the time of receiving the discharge request information is less than the threshold value.

  Further, the determination unit 216 determines whether to discharge the stored power to the commercial power network N based on whether the electric device 2 is operating with the stored power or with the power supplied from the commercial power network N. May be. For example, when the electric device 2 is not connected to a power outlet and the electric device 2 is operating with stored power, the determination unit 216 does not discharge the electric device 2 to the commercial power network N and uses the stored power. It is determined that it will continue to be used at 2.

  The determination unit 216 may determine whether or not to discharge the stored power to the commercial power network N based on the state of the electrical device 2 and the consideration for discharging from the storage battery 22 to the commercial power network N. For example, when the consideration obtained by discharging the storage battery 22 to the commercial power network N is greater than the cost required to supply the electric power acquired via the commercial power network N to the electrical device 2, the determination unit 216 stores the stored power Is discharged to the commercial power network N. Conversely, when the consideration obtained by discharging the storage battery 22 to the commercial power network N is less than the cost required to supply the electric equipment 2 with the power acquired via the commercial power network N, at least a part of the stored power Is determined to be used in the electric device 2.

  The determination unit 216 may determine whether or not to discharge the stored power to the commercial power network N based on the position of the electric device 2. For example, the determination unit 216 confirms that the electrical device 2 is connected to a power outlet in a state where the position indicated by the position information received from a GPS (Global Positioning System) satellite coincides with the registered home position. May be determined to discharge the stored power to the commercial power network N. By doing in this way, since the electric power control apparatus 1 can specify the amount discharged from the home of the user of the electric device 2, the user of the electric device 2 discharges the electric power stored in his own electric device 2. This makes it possible to receive compensation.

  The determination unit 216 may determine whether or not to discharge the stored power to the commercial power network N based on the time zone. The determination unit 216 determines that the stored power is not discharged to the commercial power network N in a time zone in which the user of the electrical device 2 is likely to use the electrical device 2 and in a time zone within a predetermined time from the time zone. In other time periods, it is determined that the stored power is discharged to the commercial power network N. The predetermined time is, for example, the time required to start charging the storage battery 22 at that time and reach a specified charge amount.

  The determination unit 216 specifies a time zone in which the commercial power network N can be discharged based on, for example, a time zone in which the electric device 2 has been used in the past. When the frequency of using the electrical device 2 is high between 6:00 pm and 9:00 pm, the determination unit 216 starts from 5:00 pm one hour before the time zone to 10 pm one hour after the time zone. During this period, it is determined that the stored power is not discharged to the commercial power network N.

  The determination unit 216 determines whether or not to discharge the stored power to the commercial power network N based on the schedule of the owner of the electric device 2 in order to improve the accuracy of estimating a time zone in which the electric device 2 is likely to be used. It may be determined. For example, if the meeting is scheduled from 2 pm to 4 pm, the determination unit 216 is from 1 pm 1 hour before the start of the meeting to 5 pm 1 hour after the meeting ends. It is determined that the stored power is not discharged to the commercial power network N.

  The display control unit 217 displays various information on the display unit 212. For example, when the stored power is discharged to the commercial power network N, the display control unit 217 displays a screen for performing an operation for stopping the discharge while displaying on the display unit 212 that the discharge is being performed. . The display control unit 217 may display a screen for setting whether or not to permit discharge in response to receiving the discharge request information from the power control device 1. When the display control unit 217 receives a setting to permit discharge, the display control unit 217 notifies the determination unit 216 that the discharge is permitted. By doing in this way, it becomes possible to determine whether to start the discharge to the commercial power grid N by the judgment of the user of the electric device 2.

  When the determination unit 216 determines that the stored power is discharged to the commercial power network N, the display control unit 217 displays a screen for selecting one or more vendors from a plurality of vendors that purchase the stored power on the display unit 212. You may let them. The display control unit 217 notifies the determination unit 216 of information indicating the selected supplier. When the determination unit 216 starts discharging to the commercial power network N, the determining unit 216 transmits information indicating the supplier to the power control apparatus 1 in association with information for specifying a time zone during which discharging is performed. In this way, the user can sell the stored power to a trader who wants to sell the stored power. The display control unit 217 may make it easier for the user to select a trader by displaying the price for discharging (that is, the power selling price) in association with each of the plurality of traders.

  The display control unit 217 may cause the display unit 212 to display a screen for accepting the setting of the allowable discharge amount in response to receiving a discharge request from the power control device 1 to the commercial power grid N. The display control unit 217 displays, for example, a discharge request amount received from the power control device 1 and a screen for a user to input a permitted discharge amount. The display control unit 217 notifies the determination unit 216 of the input allowable discharge amount. In this way, the determination unit 216 can discharge the stored power to the commercial power network N until the discharge permission amount is reached, so that it is possible to leave the amount of power desired by the user in the storage battery 22. .

[Operation Sequence in Power Control System S]
FIG. 7 is a diagram illustrating an operation sequence of the power control system S when the electric device 2 discharges to the commercial power network N. First, the power control apparatus 1 determines whether or not the power demand is equal to or greater than a threshold value (S1). When the power control device 1 determines that the power demand is equal to or greater than the threshold, the power control device 1 generates discharge request information (S2), and transmits the generated discharge request information to the electrical device 2.

  When the electrical device 2 receives the discharge request information, the state identifying unit 215 identifies the state of the electrical device 2 (S3). Subsequently, the determination unit 216 determines whether or not to discharge based on the state specified by the state specifying unit 215 (S4). When determining unit 216 determines that discharging cannot be performed (NO in S4), it transmits discharge refusal information indicating that discharging cannot be performed to power control device 1. On the other hand, when determining unit 216 determines that discharge is possible (YES in S4), it instructs display control unit 217 to display a screen for setting the allowable discharge amount on display unit 212 (S5).

  Subsequently, the determination unit 216 instructs the display control unit 217 to display a screen for selecting a supplier to be discharged on the display unit 212 (S6). When the allowable discharge amount and the trader are selected, the determination unit 216 instructs the power control circuit 23 to discharge the power stored in the storage battery 22 to the commercial power network N.

  In addition, the determination part 216 may start discharge, without performing step S5 and step S6. Further, the determination unit 216 may transmit the discharge rejection information to the power control apparatus 1 when the allowable discharge amount is not input in Step S5 or when the supplier is not selected in Step S6. In this way, it is possible to prevent the stored power from being discharged to the commercial power network N against the user's intention.

[Operation Flow of Determination Unit 216]
FIG. 8 is a flowchart showing a flow of operation of the determination unit 216. The flowchart shown in FIG. 8 starts when the electrical device 2 receives the discharge request information from the power control device 1.

  First, the state specifying unit 215 specifies the state of the electrical device 2 (S11). The determination unit 216 determines whether the function providing unit 21 is executing the function and is using power (S12). When determining that the function providing unit 21 is using a predetermined amount or more of power (YES in S12), the determining unit 216 provides power to the function providing unit 21 without discharging the stored power from the storage battery 22. Then, the function provided by the function providing unit 21 is continued (S13). If determination unit 216 determines that function providing unit 21 is not using a predetermined amount or more of power (NO in S12), it proceeds to step S14.

  Subsequently, the determination unit 216 determines whether or not the power stored in the storage battery 22 is greater than or equal to a predetermined threshold (S14). The predetermined threshold value is, for example, a margin value for power necessary for the function providing unit 21 to continue a predetermined operation for a preset time in a state where the electric device 2 is not supplied with power from the commercial power network N. It is the added value. Since the state of the electrical device 2 changes with time, the determination unit 216 may use a different threshold depending on the time zone. The determination unit 216 may switch the threshold by referring to the above-described user schedule, for example.

  When determining unit 216 determines that the electric power stored in storage battery 22 is less than a predetermined threshold (NO in S14), charging of storage battery 22 is performed (S15). When determining unit 216 determines that the electric power stored in storage battery 22 is equal to or greater than a predetermined threshold (YES in S14), information indicating the value included in the discharge request information received from power control device 1 is acquired. (S16), it is determined whether the consideration is equal to or greater than a predetermined amount (S17). If determination unit 216 determines that the consideration is not equal to or greater than the predetermined amount (NO in S17), the process ends without discharging the stored power.

  When determining that the consideration is equal to or greater than the predetermined amount (YES in S17), determining unit 216 determines whether or not the current time is included in a dischargeable time zone (S18). If determination unit 216 determines that the current time is not included in the dischargeable time zone (NO in S18), the process ends without discharging the stored power. When determining unit 216 determines that the current time is included in the dischargeable time zone (YES in S18), discharges stored power to commercial power network N (S18). Note that, when it is determined in step S <b> 17 and step S <b> 18 that the discharge is not performed, the determination unit 216 may transmit the discharge rejection information to the power control device 1.
