For example, a demand response (DR: Demand Response) is issued to the aggregator 6. The aggregator 6 receives a power saving request from the power system side 5 and makes a power saving request to one or a plurality of power demanding facilities 3 for the period, for example.

  When power saving is performed in accordance with the power saving request from the aggregator 6 in the power demand facility 3, the power demand facility 3 provides the aggregator 6 with negative power, that is, reduced power consumption. The aggregator 6 obtains a negawatt price by selling the negawatt provided from the power demand facility 3 in the wholesale power market 8.

  In addition, the power system side 5 gives the aggregator 6 an incentive for power saving, that is, a reward for power saving in the target period of the power saving request.

  The aggregator 6 distributes the negative wattage value obtained from the wholesale power market 8 and the power saving reward obtained from the power system side 5 to the power demand facility 3.

While generating electricity by the generator, hot water is supplied using the exhaust heat of the generator. Heating is performed. In the following, description will be made assuming that the cogeneration device 251 is a device that generates power and hot water using gas.

  The power consumption management device 101 is operated by, for example, the aggregator 6 and communicates with the customer device 202 in one or a plurality of power demanding facilities 3, thereby reducing the power consumption in the power demanding facility 3 in which each customer device 202 is used. to manage.

  The system side management apparatus 201 is operated by the power system side 5 and transmits power management information, which is information regarding power consumption, to the power consumption management apparatus 101. The power management information indicates, for example, the content of a power saving event in which the aggregator 6 can participate.

  Specifically, the power management information includes, as the content of the power saving event, for example, a request period in which power consumption is to be reduced in a request period in which power consumption is to be suppressed, and a request target that is to be reduced by the subordinate power demand facility 3 Indicates. For example, when the aggregator 6 determines that the requested target can be achieved, the aggregator 6 participates in the power saving event.

  The power consumption management device 101 determines whether or not the aggregator 6 participates in the power saving event indicated by the power management information based on the instruction response information received from each consumer device 202. Specifically, for example, the power consumption management apparatus 101 determines to participate in the power saving event when it is determined that the requested target can be achieved based on the reduction amount information included in each instruction response information.

  In addition, the power consumption management apparatus 101 transmits request response information indicating whether or not the aggregator 6 participates in the power saving event to the system side management apparatus 201. For example, the power consumption management apparatus 101 transmits request response information indicating participation in a power saving event including total reduction amount information indicating a total amount of power consumption scheduled to be reduced in each power demand facility 3. .

For example, it is determined that the consumer device 202 of the power demand facility 3 participates in the power saving event, and the power consumption management device 101 in the aggregator 6 participates in the power saving event. This is the case when it is determined.

  For example, even if the consumer device 202 determines to participate in the power saving event, if the power consumption management device 101 determines not to participate in the power saving event, the power demand facility 3 corresponding to the consumer device 202 saves power. I can't attend the event.

Then, the consideration information notification unit 30 notifies the consideration information received from the consideration information creation unit 28 to the consumer device 202 that is the notification destination of the instruction information.

  The instruction response acquisition unit 23 acquires the instruction response information from each consumer device 202 that is the notification destination of the instruction information and outputs the instruction response information to the participation determination unit 22.

  The participation determination unit 22 determines the achievement of the target indicated by the power management information by each power demand facility 3.

  More specifically, the participation determination unit 22 determines whether or not the own aggregator 6 participates in the power saving event. Based on the power management information received from the power management information acquisition unit 24 and each instruction response information received from the instruction response acquisition unit 23, the participation determination unit 22 determines whether to participate in the power saving event indicated by the power management information. .

  Specifically, for example, the participation determination unit 22 obtains a total value of power consumption scheduled to be reduced at each power demand facility 3 during the request period based on the reduction amount information included in each instruction response information. When the total value meets the requested target, it is determined that the participant will participate in the power saving event.

  In addition, the participation determination unit 22 creates request response information indicating whether or not the aggregator 6 participates in the power saving event, and outputs the request response information to the request response notification unit 21. When the participation determination unit 22 outputs request response information indicating participation in a power saving event to the request response notification unit 21, the participation determination unit 22 outputs the request response information including the total reduction amount information.

  The request response notification unit 21 notifies the system side management apparatus 201 of the request response information received from the participation determination unit 22.

  In addition, when the participation determination unit 22 determines to participate in the power saving event, the aggregator 6 outputs aggregator participation information indicating that the aggregator 6 participates in the power saving event to the participation notification unit 31.

  The participation notifying unit 31 notifies the aggregator participation information received from the participation determining unit 22 to the customer device 202 corresponding to the power demanding facility 3 participating in the power saving event.

  FIG. 4 is a diagram illustrating a configuration of a consumer device in the power consumption management system according to the first embodiment of the present invention.

  Referring to FIG. 4, customer device 202 includes acquisition unit 11, control unit 12, notification unit 13, sensor 14, and storage unit 15. In addition, the structure provided in the exterior of the customer apparatus 202 may be sufficient as at least any one of the sensor 14 and the memory | storage part 15. FIG.

  The acquisition unit 11 acquires instruction information and consideration information transmitted from the power consumption management apparatus 101 and outputs them to the control unit 12. The control unit 12 stores the consideration information received from the acquisition unit 11 in the storage unit 15.

  The sensor 14 measures the supply S other than electricity by the cogeneration device 251 regularly or irregularly and notifies the control unit 12 of the measurement result. Specifically, for example, the sensor 14 measures the remaining amount of hot water such as a bath in the power demand facility 3 and notifies the control unit 12 of the measurement result.

  For example, the power meter 241 measures the total power consumption in the power demand facility 3 and notifies the control unit 12 of the measurement result.

  The control unit 12 stores measurement information indicating the measurement result notified from the sensor 14 in the storage unit 15. The control unit 12 predicts the demand for the supply S in the power demand facility 3 based on the measurement information accumulated in the storage unit 15.

  Further, the control unit 12 acquires cost information required for power generation of the cogeneration device 251 and stores the cost information in the storage unit 15. Specifically, for example, the control unit 12 acquires price information of the gas supplied from the gas company to the power demand facility 3 and stores it in the storage unit 15. In this case, the gas charge corresponds to the power generation cost by the cogeneration device 251.

  The control unit 12 can start and stop the cogeneration device 251 by transmitting a control signal to the cogeneration device 251.

  Note that the control unit 12 may be configured to calculate the electricity bill saved by the power generation of the cogeneration device 251 and perform control to present the calculation result to the consumer.

  In this case, the control unit 12 acquires price information of the power supplied from the power company to the power demand facility 3 from, for example, the power meter 241 and stores it in the storage unit 15 for use in calculating the electricity bill.

  Further, in response to the instruction information being acquired by the acquisition unit 11, the control unit 12 starts a determination process for starting the cogeneration device 251 in the power demand facility 3.

  More specifically, for example, the control unit 12 determines not to start the cogeneration device 251 when it is determined in the determination process that there is no or little demand for the supply S other than electricity by the cogeneration device 251.

  Specifically, for example, in the determination process, the control unit 12 determines not to start the cogeneration device 251 when determining that the remaining amount of hot water is sufficient for the demand amount of hot water. On the other hand, for example, when determining that the remaining amount of hot water is insufficient with respect to the demand amount of hot water in the determination process, the control unit 12 determines to start the cogeneration device 251.

  In addition, in the determination process, the control unit 12 compares the value given for the suppression of power consumption with the cost required for the power generation of the cogeneration device 251 and activates the cogeneration device 251 based on the comparison result. Decide whether or not.

  FIG. 5 is a flowchart defining the procedure of power management information processing by the power consumption management apparatus according to the first embodiment of the present invention.

  With reference to FIG. 5, first, the power consumption management apparatus 101 receives, for example, power management information indicating a request period and a request target from the system-side management apparatus 201 (step S1).

  Next, the power consumption management apparatus 101 creates instruction information indicating a power saving target for each consumer apparatus 202 based on the requested target indicated by the power management information, and transmits the instruction information to each subordinate consumer apparatus 202 (step S2). .

  Next, based on the response information received from each consumer device 202, the power consumption management device 101 determines whether or not the requested target indicated by the power management information received from the grid-side management device 201 can be achieved. For example, when the power consumption management apparatus 101 receives response information indicating participation in the power saving event from a predetermined number or more of the customer apparatuses 202, the power consumption management apparatus 101 determines that the requested target can be achieved (step S3).

  When the power consumption management apparatus 101 determines that the required target can be achieved (YES in step S3), the power consumption is totaled. Specifically, the power consumption scheduled to be reduced at each power demand facility 3 during the request period. The total amount is calculated (step S4).

  Next, the power consumption management apparatus 101 performs processing for the negative watts provided from each power demand facility 3, that is, calculates the negative wattage obtained in the wholesale power market 8. In addition, when there is little power saving in each electric power demand facility 3, there may be a case where negawatts cannot be traded (step S5).

  Next, the power consumption management apparatus 101 performs incentive acquisition processing for power saving, that is, acquires incentive information indicating a reward from the power system side 5 for power saving performed in the target period of the power saving request (step S6). ).

  On the other hand, when the power consumption management apparatus 101 determines that the power saving target cannot be achieved (NO in step S3), the power consumption management apparatus 101 performs a penalty payment process to the power system side 5, for example, power saving is performed in the target period of the power saving request. An amount such as an extra charge or a penalty to be paid to the power system side 5 in response to the absence is calculated (step S7).

  FIG. 6 is a diagram showing an example of a sequence of power consumption suppression processing in the power consumption management system according to the first embodiment of the present invention. FIG. 6 shows a case where one consumer device 202 is provided in the power consumption management system 301 as an example.

  Referring to FIG. 6, first, system side management apparatus 201 predicts, for example, power demand for the next day, and determines that power consumption should be suppressed when there is a high possibility that power supply and demand will be tight (step) S10).

  More specifically, the system side management apparatus 201 predicts the overall power demand using, for example, a known demand prediction technique, specifically, a technique such as a neural network or autoregressive analysis. Or the system side management apparatus 201 calculates the total power demand by calculating the average value of the power consumption for Y days excluding the singular day from the data of the power consumption for the past X days, for example. Predict.

  Next, the system side management apparatus 201 transmits power management information and incentive information to the power consumption management apparatus 101 (step S11).

  Next, the transaction market apparatus 161 transmits transaction price information to the power consumption management apparatus 101 (step S12).

  Next, the power consumption management apparatus 101 creates instruction information for requesting suppression of power consumption in the power demand facility 3 based on the power management information received from the system side management apparatus 201. In addition, the power consumption management apparatus 101 provides compensation information indicating compensation for reducing power consumption in the power demand facility 3 based on the incentive information received from the system side management apparatus 201 and the transaction price information received from the transaction market apparatus 161. create. Then, the power consumption management device 101 transmits the created instruction information and consideration information to the customer device 202 (step S13).

  In addition, the power consumption management apparatus 101 acquires the latest transaction price information from the transaction market apparatus 161 regularly or irregularly, updates the consideration information based on the acquired transaction price information, and updates each time it is updated. The consideration information, that is, the latest consideration information may be transmitted to the customer apparatus 202.

  Next, the consumer device 202 receives the instruction information and the consideration information from the power consumption management device 101, and activates the cogeneration device 251 in the corresponding power demand facility 3 based on the received instruction information and the consideration information. Judgment processing for this is performed (step S14).

  Next, in the determination process, the consumer device 202 determines that the cogeneration device 251 is to be activated, and transmits instruction response information indicating participation in the power saving event indicated by the instruction information to the power consumption management apparatus 101 (step S15). ).

  Next, the power consumption management apparatus 101 receives the instruction response information from the customer apparatus 202, and determines whether or not the aggregator 6 participates in the power saving event indicated by the power management information (step S16). Specifically, the power consumption management apparatus 101 determines whether or not the requested target indicated by the power management information can be achieved based on the reduction amount information included in the received instruction response information.

  When determining that the requested target can be achieved, the power consumption management apparatus 101 transmits request response information indicating participation in the power saving event indicated by the power management information to the system side management apparatus 201 (step S17).

  For example, the power consumption management apparatus 101 makes the determination at a time before a predetermined time when the request period indicated by the power management information starts.

  When the power consumption management apparatus 101 determines to participate in the power saving event, the power consumption management apparatus 101 transmits the aggregator participation information to the customer apparatus 202 that has transmitted the instruction response information indicating that it participates in the power saving event to itself (step S18).

  The consumer device 202 receives the aggregator participation information from the power consumption management device 101, and performs control to activate the cogeneration device 251 at the start timing of the power saving period (step S19).

  Next, when it is determined that the demand for the supply S by the cogeneration device 251 has disappeared or has decreased, the consumer device 202 performs control to stop the cogeneration device 251 (step S20).

  Next, for example, the consumer device 202 transmits to the power consumption management device 101 power saving result information indicating that the cogeneration device 251 has been activated and the amount of power consumption reduced during the power saving period due to the operation of the cogeneration device 251. (Step S21).

  Note that the consumer device 202 may perform control to stop the cogeneration device 251 during the power saving period in accordance with the demand for the supply S, or perform control to stop the cogeneration device 251 after the power saving period ends. May be.

  Moreover, the consumer apparatus 202 may be configured to perform control to activate the cogeneration device 251 without waiting for the start timing of the power saving period when it is determined that the cogeneration device 251 is activated.

  FIG. 7 is a flowchart that defines the procedure of a determination process for activating a cogeneration device by a consumer device according to the first embodiment of the present invention.

  Referring to FIG. 7, first, when customer apparatus 202 receives instruction information from power consumption management apparatus 101 (step S <b> 21), it is necessary for power generation by consideration information stored in storage unit 15 and cogeneration device 251. Cost information is acquired (step S22).

  Next, the consumer device 202 predicts the demand for the supply S in the power demand facility 3 based on the measurement information accumulated in the storage unit 15. Specifically, for example, the consumer device 202 predicts the time when the hot water filling of the bath is required in the power demand facility 3 and the amount of hot water used, and predicts the demand from the relationship between the time and the power saving period. In this case, the consumer device 202 predicts demand divided by a period of one day, for example. Moreover, the consumer apparatus 202 can also use, for example, the demand prediction technique described in Patent Document 2 (Japanese Patent No. 4148419) (step S23).

  Next, based on the acquired consideration information and cost information, the consumer device 202 compares the electricity saving cost in the power demand facility 3 with the power generation cost of the cogeneration device 251 and the electricity saving cost is greater ( It is determined that the cogeneration device 251 is activated (YES in step S24) (step S26).

  In addition, even when the consideration for power saving is smaller (NO in step S24), the consumer device 202 uses the cogeneration device 251 when there is a large demand for supply other than electricity by the cogeneration device 251 (NO in step S25). It is determined to start (step S26).

  When determining that the cogeneration device 251 is activated, the customer apparatus 202 transmits instruction response information indicating that it participates in the power saving event indicated by the instruction information to the power consumption management apparatus 101 (step S26).

  Next, the consumer device 202 performs control to activate the cogeneration device 251 at the start timing of the power saving period (step S27).

  Next, when it is determined that the demand for the supply S by the cogeneration device 251 has disappeared or has decreased, the consumer device 202 performs control to stop the cogeneration device 251 (step S28).

  Next, for example, the consumer device 202 notifies the power consumption management device 101 of power saving result information indicating that the cogeneration device 251 has been operated and the amount of power consumption reduced during the power saving period due to the operation of the cogeneration device 251. Transmit (step S29).

  On the other hand, in the customer apparatus 202, the value of power saving in the power demand facility 3 is smaller than the power generation cost of the cogeneration device 251 (NO in step S24), and there is no demand for the supply S by the cogeneration device 251 or When the number is small (YES in step S25), it is determined that the cogeneration device 251 is not activated, and instruction response information indicating that it does not participate in the power saving event indicated by the instruction information is transmitted to the power consumption management apparatus 101 (step S30).

  By the way, in a system in which the system side operator makes a power saving request to the aggregator in advance when the power supply / demand tightness is predicted, and the aggregator makes a power saving request to the customer of the power demand facility, There is a demand for a technology that more reliably suppresses power consumption in accordance with the power saving request.

  On the other hand, in the consumer device according to the first embodiment of the present invention, the acquisition unit 11 acquires instruction information for requesting suppression of power consumption. Then, in response to the instruction information being acquired by the acquisition unit 11, the control unit 12 starts a determination process for starting the cogeneration device 251 in the power demand facility 3.

  With such a configuration, for example, an excellent system in which demand response, negative wattage, and cogeneration cooperate can be constructed. That is, the cogeneration system is not limited to a single unit, and for example, a system optimized as a whole can be constructed in consideration of demand response information, thereby achieving negative power. Specifically, the cogeneration device 251 is not activated at the scheduled timing, but is activated at an unscheduled timing in response to the power saving request, thereby effectively utilizing the cogeneration device 251 in response to the power saving request. In addition, it is possible to achieve the power saving target without causing a heavy burden on consumers such as restrictions on the use of electrical equipment. That is, not only simply achieving the power saving target, but also reducing the burden on the customer who has received the power saving request, for example, the customer can obtain an incentive for power saving.

  Therefore, the consumer device according to the first embodiment of the present invention can more reliably suppress power consumption according to the power saving request.

  Moreover, in the consumer apparatus which concerns on the 1st Embodiment of this invention, when the control part 12 judges that there is no demand for supply other than electricity by the cogeneration apparatus 251 in judgment processing, it is cogeneration. It is determined that the device 251 is not activated.

  With such a configuration, when the need for supply other than electricity by the cogeneration device 251 is low, it is possible to prevent the cogeneration device 251 from operating excessively and, for example, increase the cost in the power demand facility 3. In addition, for example, according to a contract between the consumer of the power demand facility 3 and the grid-side business operator, the level of power saving duty of the consumer can be flexibly set.

  Moreover, in the consumer apparatus which concerns on the 1st Embodiment of this invention, the control part 12 compares the consideration given with respect to suppression of electric power consumption, and the cost required for the electric power generation of the cogeneration apparatus 251 in judgment processing. Whether or not to start the cogeneration device 251 is determined based on the comparison result.

  With such a configuration, it is possible to reduce the burden on the customer when performing power saving in response to a power saving request. Specifically, for example, it is possible to prevent the cost in the power demand facility 3 from increasing in order to achieve the power saving target. In addition, for example, even when the need for supply other than electricity by the cogeneration device 251 is low, the cogeneration device 251 can be effectively used within a range where the cost of the consumer does not increase.

  Moreover, in the power consumption management system according to the first embodiment of the present invention, the cogeneration device 251 supplies hot water. And in the consumer apparatus which concerns on the 1st Embodiment of this invention, when the control part 12 judges that the remaining amount of hot water is insufficient with respect to the demand amount of hot water in judgment processing, it is the cogeneration apparatus 251. Decide to start.

  With such a configuration, it is possible to appropriately supply hot water that requires a gas charge. Specifically, for example, an increase in gas charges due to unnecessary hot water supply can be prevented. Further, by achieving the power saving target, it is possible to prevent the utility costs such as electricity and gas from increasing as a result of heat insulation of hot water.

  Note that, in the power consumption management system according to the first embodiment of the present invention, the consumer device 202 is configured to activate the cogeneration device in response to receiving the instruction information from the power consumption management device 101. Although the configuration is such that the determination process is started, the present invention is not limited to this. The consumer device 202 may be configured to start some processing for starting the cogeneration device in response to receiving the instruction information from the power consumption management device 101. Specifically, for example, the consumer device 202 has received the instruction information from the power consumption management device 101 without determining whether to start the cogeneration device 251 based on the cost, supply-demand relationship, or the like. In response, instruction response information indicating participation in the power saving event may be transmitted to the power consumption management apparatus 101, and control to activate the cogeneration device 251 at the start timing of the power saving period may be performed.

  Further, the consumer device 202 may be configured such that a part of the function of the control unit 12 such as a function of controlling the cogeneration device 251 is provided in a separate device.

  In the power consumption management system according to the first embodiment of the present invention, the power demand facility 3 may be a facility operated by a small consumer with a small contract power, such as a general household, It may be a facility such as a factory that is operated by large consumers with large contract power.

  Further, the present invention is not limited to a power consumption management system including one power consumption management device, but can also be applied to a power consumption management system including a plurality of hierarchical power consumption management devices.

  Next, another embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

The contents other than those described below are the same as those of the power consumption management system according to the first embodiment.

[Configuration and basic operation]
FIG. 8 is a diagram showing a configuration of a power consumption management system according to the second embodiment of the present invention.

  Referring to FIG. 8, the power consumption management system 302 includes a grid-side management device 201, a power consumption management device 101, one or more customer devices 202, one or more cogeneration devices 251, 1 or A plurality of customer apparatuses 212, one or a plurality of loads 261, and a transaction market apparatus 161 are provided.

The power demand facility 9 may be a facility operated by a small consumer.

  The power consumption management device 101 manages the power consumption in the power demand facility 9 in which each consumer device 212 is used by communicating with the customer device 212 in one or more power demand facilities 9.

  The power consumption management apparatus 101 creates instruction information for requesting suppression of power consumption in the power demand facility 9 based on the power management information received from the grid-side management apparatus 201, and one or more of the created instruction information To the customer device 212 in the power demand facility 9.

  The instruction information indicates, for example, the content of a power saving event in which the power demand facility 9 can participate. Specifically, the instruction information indicates a power saving period that is a period in which power consumption should be reduced in the power demand facility 9, and a power saving target that is a target of power consumption to be reduced in the power saving period.

  The customer device 212 controls a load 261 in the power demand facility 9, that is, an operation of an electrical device, thereby reducing power consumption by a BEMS (Building Energy Management System), a HEMS (Home Energy Management System), or a FEMS (Factor). This is a device used in a system such as an energy management system, and is introduced by an aggregator 6, for example.

  The consumer device 212 controls the load 261 based on the instruction information received from the power consumption management device 101. Specifically, for example, the consumer device 212 performs control to increase the set temperature of the air conditioning that is the load 261 by 2 ° C. or to turn off the corridor lighting that is the load 261.

  The power consumption management apparatus 101 may be configured to transmit instruction information indicating the control content of the load 261 as described above to the customer apparatus 212. In this case, for example, the power consumption management device 101 distinguishes the control contents for each customer device 212 and stores them in a database or the like.

  In the power consumption management system 302, the instruction creation unit 25 and the instruction notification unit 26 in the power consumption management apparatus 101 are consumers used in the power demand facility 9 when the power management information is acquired by the power management information acquisition unit 24. The device 212 is notified of instruction information for requesting suppression of power consumption.

  The participation determination unit 22 determines the achievement of the target indicated by the power management information by each power demand facility 9.

  When the participation determining unit 22 determines that the target cannot be achieved, the instruction creating unit 25 and the instruction notifying unit 26 consume power to the consumer device 202 used in the power demand facility 3 in which the cogeneration device 251 is provided. Instruction information for requesting suppression is notified.

  More specifically, the power consumption management apparatus 101 is a price indicating the price for reducing power consumption in the power demand facility 9 based on the incentive information from the system side management apparatus 201 and the transaction price information from the transaction market apparatus 161. Information is created and transmitted to the customer device 212 that is the transmission destination of the instruction information.

  For example, when the power demand facility 9 participates in a power saving event, the consideration information includes a consideration for reducing the power consumption given to the power demand facility 9 according to, for example, the amount of power consumed in the power demand facility 9. Show.

  Based on the instruction information received from the power consumption management apparatus 101, the consumer device 212 determines whether or not the power demand facility 9 should participate in the power saving event indicated by the instruction information, and uses the instruction response information indicating the determination result as power. Transmit to the consumption management device 101. That is, the instruction response information indicates whether or not the power demand facility 9 participates in the power saving event.

  For example, the consumer device 212 transmits the instruction response information indicating that it participates in the power saving event including the reduction amount information indicating the amount of power consumption scheduled to be reduced in its own power demand facility 9 during the power saving period.

  Based on the instruction response information received from each consumer device 202 and each consumer device 212, the power consumption management device 101 determines whether or not the aggregator 6 participates in a power saving event indicated by the power management information. Specifically, for example, the power consumption management apparatus 101 determines to participate in the power saving event when it is determined that the requested target can be achieved based on the reduction amount information included in each instruction response information.

  In addition, the power consumption management apparatus 101 transmits request response information indicating whether or not the aggregator 6 participates in the power saving event to the system side management apparatus 201. The power consumption management apparatus 101 includes, for example, a total reduction amount indicating a total value of power consumption scheduled to be reduced in each power demand facility 3 and each power demand facility 9 in request response information indicating participation in a power saving event. Send including information.

  That is, the power demand facility 9 can participate in the power saving event. For example, it is determined that the consumer device 212 of the power demand facility 9 participates in the power saving event, and the power consumption management device 101 in the aggregator 6 participates in the power saving event. This is the case when it is determined.

  For example, even when the consumer device 212 determines to participate in the power saving event, if the power consumption management device 101 determines not to participate in the power saving event, the power demand facility 9 corresponding to the consumer device 212 saves power. I can't attend the event.

  The power consumption management device 101 is not limited to a configuration directly connected to the grid-side management device 201, each customer device 202, each customer device 212, and the transaction market device 161, but is connected via another device. It may be a configuration.

[Operation]

  FIG. 9 is a flowchart defining the procedure of power management information processing by the power consumption management apparatus according to the second embodiment of the present invention.

  With reference to FIG. 9, first, the power consumption management apparatus 101 receives, for example, power management information indicating a request period and a request target from the system-side management apparatus 201 (step S51).

  Next, the power consumption management device 101 creates instruction information indicating a power saving target for each customer device 212 based on the request target indicated by the power management information, and transmits the instruction information to each subordinate customer device 212 (step S52). .

  Next, based on the response information received from each consumer device 212, the power consumption management device 101 determines whether or not the requested target indicated by the power management information received from the grid-side management device 201 can be achieved. For example, if the power consumption management apparatus 101 receives response information indicating participation in a power saving event from a predetermined number or more of the customer apparatuses 212, the power consumption management apparatus 101 determines that the requested target can be achieved (step S53).

  If the power consumption management apparatus 101 determines that the requested target cannot be achieved (NO in step S53), the power consumption management apparatus 101 creates instruction information indicating a power saving target for each consumer device 202 based on the requested target indicated by the power management information, To each consumer device 202 (step S54).

Judgment is made. For example, when the power consumption management apparatus 101 receives response information indicating participation in the power saving event from a predetermined number of customer apparatuses 202 or more, it determines that the requested target can be achieved (step S55).

  When the power consumption management apparatus 101 determines that the requested target can be achieved (YES in step S53 or YES in step S55), the power saving amount is totaled. Specifically, in each of the power demanding facilities 3 and 9 during the request period. A total value of power consumption scheduled to be reduced is calculated (step S56).

  Next, the power consumption management apparatus 101 performs processing for the negative watts provided from the respective power demanding facilities 3 and 9, that is, calculates the negative wattage obtained in the wholesale power market 8 (step S57).

  Next, the power consumption management apparatus 101 performs incentive acquisition processing for power saving, that is, acquires incentive information indicating a reward from the power system side 5 for power saving in the target period of the power saving request (step S58). ).

  On the other hand, when the power consumption management apparatus 101 determines that the power saving target cannot be achieved (NO in step S53 and NO in step S55), the power consumption management apparatus 101 performs a penalty payment process to the power system side 5, for example, a target period for a power saving request In step S59, the amount to be paid to the power system side 5 is calculated for the fact that no power saving was performed in step S59.

  FIG. 10 is a diagram illustrating an example of a sequence of power consumption suppression processing in the power consumption management system according to the second embodiment of the present invention. FIG. 10 shows, as an example, a case where one consumer device 202 and one consumer device 212 are provided in the power consumption management system 302.

  The power consumption management device 101 receives power management information indicating a target of power consumption, and transmits instruction information for requesting suppression of power consumption to the customer device 212 used in the power demand facility 9.

  The customer apparatus 212 used in the power demand facility 9 receives the instruction information from the power consumption management apparatus 101 and transmits response information to the received instruction information to the power consumption management apparatus 101.

  The power consumption management device 101 receives the response information from the customer device 212 used in the power demand facility 9, and supplies the power consumption to the customer device 202 used in the power demand facility 3 in which the cogeneration device 251 is provided. Instruction information for requesting suppression is transmitted.

  Specifically, referring to FIG. 10, the operations in steps S70 to S72 are the same as the operations in steps S10 to S12 shown in FIG.

  Next, the power consumption management apparatus 101 creates instruction information for requesting suppression of power consumption in the power demand facility 9 based on the power management information received from the system side management apparatus 201. In addition, the power consumption management device 101 displays compensation information indicating compensation for reducing power consumption in the power demand facility 9 based on the incentive information received from the system side management device 201 and the transaction price information received from the transaction market device 161. create. Then, the power consumption management device 101 transmits the created instruction information and consideration information to the customer device 212 (step S73).

  In addition, the power consumption management apparatus 101 acquires the latest transaction price information from the transaction market apparatus 161 regularly or irregularly, updates the consideration information based on the acquired transaction price information, and updates each time it is updated. The consideration information, that is, the latest consideration information may be transmitted to the customer apparatus 212.

  Next, the consumer device 212 receives the instruction information and the consideration information from the power consumption management device 101, and accepts the power saving target indicated by the received instruction information based on the received instruction information and the consideration information. A determination is made (step S74).

  Next, the consumer device 212 determines that it cannot accept the power saving target indicated by the received instruction information, and transmits instruction response information indicating that it does not participate in the power saving event to the power consumption management device 101 (step S75). .

  Next, the power consumption management device 101 receives the instruction response information indicating that it does not participate in the power saving event from the consumer device 212, and determines that the requested target indicated by the power management information cannot be achieved. Then, the power consumption management apparatus 101 creates instruction information for requesting suppression of power consumption in the power demand facility 3 based on the power management information received from the system side management apparatus 201. In addition, the power consumption management apparatus 101 provides compensation information indicating compensation for reducing power consumption in the power demand facility 3 based on the incentive information received from the system side management apparatus 201 and the transaction price information received from the transaction market apparatus 161. create. Then, the power consumption management device 101 transmits the created instruction information and consideration information to the customer device 202 (step S76).

  In addition, the power consumption management apparatus 101 acquires the latest transaction price information from the transaction market apparatus 161 regularly or irregularly, updates the consideration information based on the acquired transaction price information, and updates each time it is updated. The consideration information, that is, the latest consideration information may be transmitted to the customer apparatus 202.

  Next, the consumer device 202 receives the instruction information and the consideration information from the power consumption management device 101, and activates the cogeneration device 251 in the corresponding power demand facility 3 based on the received instruction information and the consideration information. Judgment processing for this is performed (step S77).

  Next, in the determination process, the consumer device 202 determines that the cogeneration device 251 is to be activated, and transmits instruction response information indicating participation in the power saving event indicated by the instruction information to the power consumption management apparatus 101 (step S78). ).

  Next, the power consumption management apparatus 101 receives the instruction response information from the customer apparatus 202, and determines whether or not the aggregator 6 participates in the power saving event indicated by the power management information (step S79). Specifically, the power consumption management apparatus 101 determines whether or not the requested target indicated by the power management information can be achieved based on the reduction amount information included in the received instruction response information.

  When determining that the requested target can be achieved, the power consumption management apparatus 101 transmits request response information indicating participation in the power saving event indicated by the power management information to the system side management apparatus 201 (step S80).

  For example, the power consumption management apparatus 101 makes the determination at a time before a predetermined time when the request period indicated by the power management information starts.

  When the power consumption management apparatus 101 determines to participate in the power saving event, the power consumption management apparatus 101 transmits the aggregator participation information to the customer apparatus 202 that has transmitted the instruction response information indicating that it participates in the power saving event to itself (step S81).

  The operations in steps S82 to S84 are the same as the operations in steps S19 to S21 shown in FIG.

  The contents of the instruction information transmitted from the power consumption management apparatus 101 to the consumer apparatus 212 and the instruction information transmitted to the consumer apparatus 202 may be the same or different.

  Further, in the power consumption management system 302 including a plurality of consumer devices 212 and a plurality of consumer devices 202, the power consumption management device 101 is based on the reduction amount information included in the instruction response information received from each consumer device 212. When it is determined that the requested target indicated by the power management information cannot be achieved, for example, the reduction amount information from one or a plurality of customer devices 212 that transmitted instruction response information indicating participation in a power saving event is indicated. A request indicated by the power management information based on the sum of the power consumption amount and the power consumption amount indicated by the reduction amount information from the one or more consumer devices 202 that transmitted the instruction response information indicating participation in the power saving event. It may be determined whether or not the target can be achieved.

  As described above, in the power consumption management apparatus according to the second embodiment of the present invention, the power management information acquisition unit 24 acquires power management information indicating a target of power consumption. When the power management information is acquired by the power management information acquisition unit 24, the instruction creation unit 25 and the instruction notification unit 26 request the consumer device 212 used in the power demand facility 9 to suppress power consumption. Notify the instruction information. The participation determination unit 22 determines whether the power demand facility 9 achieves the target indicated by the power management information. Then, when the participation determining unit 22 determines that the target cannot be achieved, the instruction creating unit 25 and the instruction notifying unit 26 are connected to the customer device 202 used in the power demand facility 3 in which the cogeneration device 251 is provided. Instruction information for requesting suppression of power consumption is notified.

  In the power consumption management system according to the second embodiment of the present invention, the power consumption management device 101 receives power management information indicating a target of power consumption, and is used in the power demand facility 9. Instruction information for requesting suppression of power consumption is transmitted to 212. The customer apparatus 212 used in the power demand facility 9 receives the instruction information from the power consumption management apparatus 101 and transmits response information to the received instruction information to the power consumption management apparatus 101. Then, the power consumption management device 101 receives the response information from the customer device 212 used in the power demand facility 9, and moves to the customer device 202 used in the power demand facility 3 in which the cogeneration device 251 is provided. Instruction information for requesting suppression of power consumption is transmitted.

  With such a configuration, for example, an excellent system in which demand response, negative wattage, and cogeneration cooperate can be constructed. That is, not only the cogeneration system alone but also, for example, demand response information can be taken into consideration to construct a system optimized as a whole and achieve negative power. Specifically, the cogeneration device 251 is not activated at the scheduled timing, but is activated at an unscheduled timing in response to the power saving request, and the cogeneration device 251 is effectively used for the power saving request. Can do.

  Therefore, in the power consumption management device and the power consumption management system according to the second embodiment of the present invention, it is possible to more reliably suppress power consumption according to the power saving request.

  In addition, for example, when a large-volume consumer alone cannot achieve a power saving request, the shortage can be saved by using a cogeneration system such as a general household to achieve negative power. That is, when a large-volume consumer alone cannot achieve a power-saving request, it is possible to provide a new power-saving means that compensates for the shortage by collecting the power-saving amount of the small-volume consumer.

  In addition, for example, a request for power saving can be made to a large-volume consumer who has a large contract power at first, and a power-saving request can be made to a small-sized consumer when the large-volume consumer alone cannot achieve the power saving request. Can be done.

  That is, assuming that there are a considerable number of consumers who do not comply with the power saving request, the range of methods for achieving the power saving request can be expanded, and the possibility that the power saving request cannot be achieved can be reduced.

  In addition, the request for power saving is made in the order of large consumers and small consumers, so that the probability of making power saving requests to small consumers is lower than in the configuration where power saving requests are made without distinguishing each consumer. Thus, when a large-volume consumer can achieve a power saving request, it is possible to prevent the small-volume consumer from being restricted with respect to the use of electric power and the use of hot water.

  In addition, it is assumed that small consumers do not comply with power saving requests due to individual circumstances. For example, by making power saving requests to a large number of small consumers, it is possible to accumulate power savings little by little in the entire system. Therefore, the possibility that the power saving request cannot be achieved can be reduced.

  Since other configurations and operations are the same as those of the power consumption management system according to the first embodiment, detailed description thereof will not be repeated here.

  The above embodiment should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
