In addition to the power supply, an operation control signal (modulated electric signal) for controlling the operation of the power consuming device 70 is sent from the power supply control device 40. Note that the power consuming device 70 according to the first embodiment is not a power consuming device according to the present disclosure. The power consuming device of the present disclosure will be described in the eighth to ninth embodiments.

In Embodiment 1 or Embodiments 2 to 9 described later, the power (power packet structure) supplied to the power consuming device is composed of a header portion 81 and a payload 82 as shown in FIG. 1B.

Upon receiving the identification information, the power receiving possibility determination device 30 analyzes the power generation source information in the identification information. For example, it is assumed that the storage unit that configures the power reception availability determination device 30 stores in advance power reception information indicating that green energy is received but power other than that is rejected. Such power reception information may be determined in advance by the user of the power control apparatus 10 and input to the power reception availability determination apparatus 30. More specifically, a code indicating green energy is stored in the storage unit, and the power reception availability determination device 30 can check whether or not the code that is the power generation source information matches the code stored in the storage unit. That's fine. If the received power is green energy as a result of the analysis of the power generation source information by the power reception permission determination device 30, the power reception permission determination device 30 gives an instruction to the power supply control device 40 to receive power and receives the instruction.

Example 2 is a modification of Example 1. In the second embodiment, the power reception availability determination device 30 further determines whether or not to receive power based on the amount of power supplied from the outside. In the second embodiment, the header portion 81 includes not only the power generation source information but also information related to the power supply amount as identification information. The storage means constituting the power reception availability determination device 30 stores in advance power reception information indicating that green energy is received but power other than that is rejected, and further includes information on the power supply amount. Based on the power supply amount information (when the power supply amount information is less than the predetermined power supply amount information, information that power is not received) is stored in advance. The power reception information and the power supply amount information may be determined in advance by the user of the power control device 10 and input to the power reception availability determination device 30.

Even in the second embodiment, the identification information separation device 20 separates the header portion 81 and the payload 82 from the power (power packet structure) configured from the header portion 81 and the payload 82, and determines whether or not the identification information can be received. 30, and a payload 82 corresponding to power is sent to the power supply control device 40.

It is supplied to the consumer device 70. On the other hand, if the received power is power other than green energy as a result of the analysis of the power generation source information by the power acceptability determination device 30, or the power supply amount information included in the identification information is less than the predetermined power supply amount If the power supply control device 40 receives the instruction, the power supply control device 40 receives the instruction from the identification information separation device 20. The supply of the transmitted power to the power consuming device 70 is stopped. If the power consuming device is composed of a capacitor, the power storage is stopped.

Example 3 is a modification of Example 2. The power control apparatus 10 according to the third embodiment further includes a power supply priority order storage device that stores power supply priority orders for the power consuming devices 70.

In the third embodiment, as a result of the analysis of the power generation source information by the power reception propriety determination device 30, the received power is green energy power, but the power supply amount information included in the identification information is a predetermined power supply. If the information is less than the amount, the power reception availability determination device 30 notifies the power supply control device 40 to that effect. Then, the power supply control device 40 performs power supply stop, operation stop, power supply amount reduction, or power usage amount reduction to the power consuming device 70 according to the power supply priority order. Alternatively, the power supply control device 40 makes an inquiry to the power consuming device 70 before stopping the power supply or starting to reduce the power supply amount, and stops the power supply, stops the operation, decreases the power supply amount, When receiving information from the power consuming device 70 that the power consumption device 70 should be prohibited from reducing the usage amount, the power supply to the power consuming device 70 is not stopped, and other power consuming devices 70 are not affected. , Stop power supply, stop operation, reduce power supply amount, or reduce power consumption.

In the third embodiment, the power supply priority storage device stores power consuming devices that should be prohibited from stopping power supply, stopping operation, reducing power supply, or reducing power consumption. Since the control device performs power supply stop, operation stop, power supply amount reduction, or power consumption reduction to the power consuming device 70 in accordance with the power supply priority, there is a case where the power supply amount becomes insufficient. However, it is possible to safely stop the power supply to the power consuming device, stop the operation, reduce the power supply amount, or reduce the power consumption.
