<First Embodiment>
[Configuration and basic operation]
FIG. 1 is a diagram for explaining an outline of a power consumption management system according to an embodiment of the present invention.

  Referring to FIG. 1, power system side 5, such as an electric power company or a system operating company, makes a power saving request to aggregator 6. The aggregator 6 receives a power saving request from the power system side 5 and makes a power saving request to each power demand facility 7. The power demand facility 7 is a house, a building, a factory, or the like.

  By saving power in each power demand facility 7, the power demand facility 7 provides the aggregator 6 with negative power, that is, reduced power consumption. The aggregator 6 provides negative wattage provided from each power demand facility 7 to the power system side 5.

  On the other hand, the power system side 5 pays the aggregator 6 an incentive, that is, a price for power saving. The aggregator 6 distributes the consideration received from the power system side 5 to each power demand facility 7.

  FIG. 2 is a diagram showing the configuration of the power consumption management system according to the first embodiment of the present invention.

  Referring to FIG. 2, the power consumption management system 1 includes a system side management device 101, a power consumption management device 201, and a plurality of customer devices 301.

  The system side management apparatus 101 is operated by the power system side, and transmits power management information regarding power consumption to the power consumption management apparatus 201. The power management information includes, for example, target information indicating a target of power consumption in a period in which power saving is necessary, electric charge information indicating, for example, an electric charge per hour of power consumption 1 kWh, or an aggregator 6 according to a reduction amount of power consumption. Incentive information indicating the content of the consideration paid to is included.

  The electricity charge information is created based on a charge system selected from a plurality of charge systems such as a charge by time zone, a charge by peak, a real-time charge, and a uniform charge.

  For example, the hourly charge is a charge system in which the unit price of the electricity charge is set for each time slot. The peak fee is the same as the hourly fee in normal times, but is a fee structure in which the unit price is increased in an emergency or when the power price rises. The unit price in an emergency is, for example, 4 to 7 times the normal value. The real-time fee is a fee system in which a unit price per hour is set on the previous day, for example. The flat fee is a fee system in which the unit price is constant regardless of time, for example.

  The consumer device 301 is provided in the power demand facility 7. The consumer device 301 is a device used in a system such as BEMS or HEMS for controlling power consumption by controlling the operation of the electrical equipment in the power demand facility 7, and is introduced by the aggregator 6, for example.

  The power consumption management apparatus 201 is operated by, for example, the aggregator 6 and manages power consumption in each power demand facility in which the consumer apparatus 301 is installed by communicating with one or more consumer apparatuses 301.

  Specifically, the power consumption management device 201 creates instruction information related to power consumption in the power demand facility 7 based on the power management information received from the grid-side management device 101, and sends it to one or a plurality of customer devices 301. Notice.

  Specifically, the instruction information indicates the content of a power saving event, for example. That is, the instruction information indicates a power saving period in which power consumption should be suppressed, and a power saving target that is a power consumption amount to be reduced in the power saving period. The instruction information may further indicate the unit price of the electricity bill. Further, the power saving target is not limited to the power consumption to be reduced, and may be, for example, a reduction rate or a reduction rate, or may be an upper limit value of target power consumption.

  Further, the power consumption management device 201 collects and holds information such as power consumption in each consumer device 301. Specifically, for example, the consumer device 301 transmits power consumption information indicating power consumption in the power demand facility 7 in which the customer device 301 is installed to the power consumption management device 201 regularly or irregularly. The power consumption management device 201 stores the content of the power consumption information received from the consumer device 301.

  The customer apparatus 301 receives the instruction information from the power consumption management apparatus 201 and transmits instruction response information indicating whether or not to follow the contents of the instruction information to the power consumption management apparatus 201. Specifically, the instruction response information is information indicating whether or not the power demand facility 7 participates in the power saving event indicated by the instruction information. Whether or not to participate in the power saving event is determined by the customer device 301 based on, for example, the contents set in advance by the administrator of the customer device 301. Note that the administrator may directly determine whether or not to participate in the power saving event, for example.

  For example, when the power consumption management device 201 receives instruction response information indicating that it does not participate in the power saving event from a plurality of consumer devices 301, the power consumption management device 201 determines that the power consumption cannot be sufficiently reduced and determines one or more demands. Instruction information is newly transmitted to the home device 301.

  The power consumption management device 201 is not limited to the configuration directly connected to the grid-side management device 101 and each customer device 301, but is connected to the grid-side management device 101 and each customer device 301 via other devices.

(Protocol / Internet Protocol). The message is described in XML (Extensible Markup Language), and the data structure of the message is defined in XSD (XML Schema Definition).

  FIG. 4 is a diagram illustrating an example of the content of the instruction information that can be transmitted to the customer device according to the communication protocol defined by OpenADR2.0 by the power consumption management device according to the embodiment of the present invention.

  Referring to FIG. 4, the power consumption management apparatus 201 uses, as instruction information, a consumer device 301 that includes a power saving period that is a target period of a power saving event, a date and time when the content of the power saving event is notified, and a start date and time of the power saving event. Can be sent to. In addition, the power consumption management apparatus 201 can divide the power saving period into periods 1 to 3 and transmit the unit price of the electricity charge in each period to the customer apparatus 301.

  Further, the power consumption management apparatus 201 can divide the power saving period into periods A to D, and transmit the power consumption to be reduced in each period to the customer apparatus 301.

  Here, in the communication protocol according to OpenADR2.0, it is difficult to transmit / receive information of unregistered contents. Specifically, for example, the customer apparatus 301 transmits information Y to the power consumption management apparatus 201 when the information Y used to request information to be acquired is unregistered in communication according to the communication protocol. Difficult to do.

  FIG. 5 is a diagram illustrating an example of a sequence when the power consumption management apparatus according to the embodiment of the present invention transmits instruction information in accordance with a communication protocol defined in OpenADR2.0.
