Specifically, for example, when the power consumption management apparatus 201 determines that the requested target can be achieved based on the reduction amount information included in each instruction response information, the power consumption management apparatus 201 determines to participate in the power saving event.

  In addition, the power consumption management apparatus 201 transmits request response information indicating whether or not the aggregator 6 participates in the power saving event to the system side management apparatus 101. When the power consumption management apparatus 201 transmits request response information indicating that it participates in a power saving event to the grid-side management apparatus 101, the total reduction amount indicating the total power consumption amount scheduled to be reduced in each power demand facility 7 Information is included in the request response information and transmitted.

  Here, the power demand facility 7 can participate in the power saving event. For example, it is determined that the production management device 302 of the power demand facility 7 participates in the power saving event, and the power consumption management device 201 in the aggregator 6 becomes the power saving event. This is when it is decided to participate.

  For example, even when the production management device 302 determines to participate in the power saving event, if the power consumption management device 201 determines not to participate in the power saving event, the power demand facility 7 in which the production management device 302 is installed is I cannot participate in a power saving event.

The numbers in the rectangular frame represent the time required for each process, and the capital letters in the frame represent the production equipment 303 used in each process. For example, “A” represents the production facility 303A, and “B” represents the production facility 303B.

  FIG. 5 shows, for example, processing the product of step a into products different from each other in steps b, c, d and steps e, f, g, and using the product of step d and the product of step g. To complete.

  The routes of processes a, e, f, and g represented by thick arrows represent critical paths. In addition, the routes of steps b, c, and d represented by thin arrows represent routes other than the critical path. That is, the routes of the processes b, c, and d have a time margin as compared with the routes of the processes e, f, and g included in the critical path.

  Specifically, the time taken for the steps b, c, d is 3 hours + 3 hours + 3 hours = 9 hours, whereas the time taken for the steps e, f, g is 5 hours + 8 hours + 9 hours = 19 hours. It is.

  From this, if the steps b, c, d can be completed at the time until the steps e, f, g are completed, for example, even if the period for performing the steps b, c, d is delayed, the entire process There is no delay.

  Referring to FIG. 7, table B <b> 2 shows the period during which each step shown in FIG. 5 is performed in the alternative plan, the production facility 303 to be used, and the power consumption of production facility 303. The period from 8:00 to 13:00 is a power saving period.

  The planning unit 42 formulates an alternative plan shown in FIG. 7 based on the instruction information and various types of information stored in the storage unit 45. In the alternative plan, processes b, c, and d, which are processes on routes other than the critical path, are not performed from 8 o'clock to 13 o'clock, which is a power saving period.

  Specifically, in the alternative plan, the process b is performed using the production facility 303B from 15:00 to 18:00, and the process c is performed using the production facility 303C from 18:00 to 21:00. The process d is performed using the production equipment 303D between 21:00 and 24:00.

  Note that the planning unit 42 may make an alternative plan that does not continuously perform the steps b, c, and d. Specifically, for example, the planning unit 42 performs the process b from 5 o'clock to 7 o'clock, the process c from 13 o'clock to 16 o'clock, and the process d from 19 o'clock to 22 o'clock An alternative plan to be implemented in between may be drawn up.

  When planning the alternative plan, the planning unit 42 determines how much merit is obtained when the production plan is changed from the existing plan to the alternative plan. Specifically, for example, the planning unit 42 determines how much financial merit there is.

  FIG. 8 is a diagram illustrating an example of calculation of numerical values used by the planning unit in the production management apparatus according to the embodiment of the present invention to determine the merit of the alternative plan.

  Referring to FIG. 8, table B3 includes power consumption P1 that is power consumption per hour when each process is performed according to the existing plan, ie, table B1 shown in FIG. 6, and alternative plan, ie, table B2 shown in FIG. The power consumption P2 which is the power consumption for every hour when each process is implemented is shown.

  Further, the table B3 shows the unit price of electricity per hour U which is the unit price of electricity charges, the electricity rate M1 which is the hourly electricity charge when each process is performed according to the existing plan, and the process according to the alternative plan. An electricity bill M2 which is an hourly electricity bill when implemented is shown.

  The electricity bill M1 is obtained by the product of the power consumption P1 and the electricity unit price U. The electricity bill M2 is obtained by the product of the power consumption P2 and the electricity unit price U.

  Further, the table B3 shows a reduction power amount D that is a power consumption amount that is reduced when the production plan is changed from the existing plan to the alternative plan for every hour, and a consideration that is a unit price of the power saving consideration indicated in the consideration information. The unit price Q and the power saving consideration T, which is the power saving consideration that can be obtained when production is performed according to the alternative plan, are shown.

  From 8 o'clock to 12 o'clock is a power saving period. Here, it is assumed that power saving consideration occurs during the power saving period, and power saving consideration does not occur during a period other than the power saving period. That is, the consideration unit price Q is set in the power saving period. The reduced power amount D is obtained from the difference between the power consumption P1 and the power consumption P2. The power saving consideration T is obtained by the product of the reduced electric energy D and the consideration unit price Q.

  The table B3 indicates the total value of the power consumption P1, the total value of the power consumption P2, the total value of the electricity rate M1, the total value of the electricity rate M2, and the total value of the power saving consideration T from 0:00 to 24:00. .

  The planning unit 42 determines the merit of the alternative plan based on the total value of the electricity rate M1, the total value of the electricity rate M2, and the total value of the power saving consideration T.

  For example, the planning unit 42 obtains a substantial electricity charge Ma2 when each process is performed according to the alternative plan from the difference between the total value of the electricity charge M2 and the total value of the power saving consideration T. Specifically, the electricity bill Ma2 = 10620 yen-4300 yen = 6320 yen.

  Then, the planning unit 42 calculates a reduction cost Ct that is a cost that can be reduced when the production plan is changed from the existing plan to the alternative plan from the difference between the total value of the electricity rate M1 and the electricity rate Ma2. Specifically, the reduction cost Ct = 10830 yen-6320 yen = 4510 yen.

[Specific Example 2]
FIG. 9 is a diagram showing an example of an existing plan arrow diagram formulated by the planning unit in the production management apparatus according to the first embodiment of the present invention. FIG. 10 is a diagram showing an example of a Gantt chart of an existing plan formulated by the planning unit in the production management apparatus according to the first embodiment of the present invention.

  Referring to FIG. 9, arrows m to p represent steps m to p, respectively. Numbers 10, 20, 30, 40, and 50 represent a separation between processes. The numbers in the rectangular frame represent the time required for each process, and the capital letters in the frame represent the production equipment 303 used in each process. For example, “A” represents the production facility 303A, and “B” represents the production facility 303B.

  Here, a series of steps shown in FIG. 9 represents a critical path. Therefore, it is not possible to delay the end time in all processes.

  With reference to FIG. 10, table B11 shows the power consumption of production equipment 303 to be used and the production equipment 303 during the period when each step shown in FIG.

  The power used by the production facility 303A is 10 kW, the power used by the production facility 303B is 20 kW, the power used by the production facility 303C is 30 kW, and the power used by the production facility 303D is 10 kW. The electric power used by 303E is 50 kW, and the electric power used by the production facility 303F is 60 kW.

  In the existing plan, as the process in the critical path, the process m is performed using the production facility 303A from 0:00 to 5:00, and the process n is performed using the production facility 303B from 5:00 to 10:00. Then, the process o is performed using the production facility 303C from 10:00 to 18:00, and the process p is performed using the production facility 303D from 18:00 to 24:00.

  FIG. 11 is a diagram illustrating an example of a Gantt chart of an alternative plan prepared by the planning unit in the production management apparatus according to the first embodiment of the present invention.

  Referring to FIG. 11, table B12 shows the period during which each step shown in FIG. 9 is carried out in the alternative plan, the production facility 303 to be used, and the power consumption of production facility 303. From 8 o'clock to 12 o'clock is a power saving period.

  The planning unit 42 formulates an alternative plan shown in FIG. 11 based on the instruction information and various information stored in the storage unit 45. In the alternative plan, the process is not carried out during the power saving period from 8:00 to 13:00.

  Specifically, in the alternative plan, the process m is performed using the production facility 303A from 0:00 to 5:00, and the process n1 is performed using the production facility 303B from 5:00 to 8:00. The process n2 is performed using the production equipment 303E between 6:00 and 8:00.

  Step n1 and step n2 correspond to step n in the existing plan shown in FIG. Specifically, the process n1 corresponds to the process from 5:00 to 8:00 in the existing process n. The process n2 corresponds to the process from 8:00 to 10:00 in the process n of the existing plan.

  In the alternative plan, the process o1 is performed using the production facility 303C from 13:00 to 18:00, the process o2 is performed using the production facility 303F from 13:00 to 16:00, and 18:00 To 24 o'clock, the process p is performed using the production facility 303D.

  Step o1 and step o2 correspond to step o in the existing plan shown in FIG. Specifically, the process o1 corresponds to the process from 10:00 to 15:00 in the process o of the existing plan, and the process o2 corresponds to the process from 15:00 to 18:00 in the process o of the existing plan.

  In this way, in the alternative plan, the power consumption in the power demand facility 7 is reduced by not using the production facility 303 during the power saving period from 8:00 to 13:00.

  When planning the alternative plan, the planning unit 42 determines how much merit is obtained when the production plan is changed from the existing plan to the alternative plan. Specifically, for example, the planning unit 42 determines how much financial merit there is.

  FIG. 12 is a diagram illustrating an example of calculation of numerical values used by the planning unit in the production management apparatus according to the embodiment of the present invention to determine the merit of the alternative plan.

  Referring to FIG. 12, table B13 includes power consumption P11 that is power consumption per hour when each process is performed according to the existing plan, that is, table B11 shown in FIG. 10, and alternative plan, that is, table B2 shown in FIG. The power consumption P12 which is the power consumption for every hour when each process is implemented is shown.

  Further, the table B13 shows the unit price of electricity per hour U1 that is the unit price of electricity charges per hour, the electricity rate M11 that is the hourly electricity charge when each process is performed according to the existing plan, and the process according to the alternative plan. An electricity charge M12, which is an hourly electricity charge when implemented, is shown.

  The electricity bill M11 is obtained by the product of the power consumption P11 and the electricity unit price U1. The electricity bill M12 is obtained by the product of the power consumption P12 and the electricity unit price U1.

  Further, the table B13 includes a reduction power amount D1 that is a power consumption amount that is reduced when the production plan is changed from the existing plan to the alternative plan, and a consideration that is a unit price of the power saving consideration indicated in the consideration information. The unit price Q1 and the power saving consideration T1, which is the power saving consideration that can be acquired when production is performed according to the alternative plan, are shown.

  The period from 8:00 to 13:00 is a power saving period. Here, it is assumed that power saving consideration occurs during the power saving period, and power saving consideration does not occur during a period other than the power saving period. That is, the consideration unit price Q1 is set in the power saving period. The reduced power amount D1 is obtained from the difference between the power consumption P11 and the power consumption P12. The power saving consideration T1 is obtained by the product of the reduced power amount D1 and the consideration unit price Q1.

  Table B13 shows the total value of power consumption P11 from 0 o'clock to 24:00, the total value of power consumption P12, the total value of electricity bill M11, the total value of electricity bill M12, and the total value of power saving consideration T1.

  The planning unit 42 determines the merit of the alternative plan based on the total value of the electricity rate M11, the total value of the electricity rate M12, the total value of the power saving consideration T1, and the like.

  Here, an expense caused by performing production according to the alternative plan, for example, an expense R1 caused by operating the production facility 303E and the production facility 303F that are not normally operated is set to 2000 yen.

  For example, the planning unit 42 adds the cost R1 to the difference between the total value of the electricity charge M12 and the total value of the power saving consideration T1, thereby obtaining a substantial electricity charge Ma12 when each process is performed according to the alternative plan. . Specifically, the electricity bill Ma12 = 7430 yen-5000 yen + 2000 yen = 4430 yen.

  Then, the planning unit 42 calculates a reduction cost Ct that is a cost that can be reduced when the production plan is changed from the existing plan to the alternative plan from the difference between the total value of the electricity rate M11 and the electricity rate Ma12. Specifically, the reduction cost Ct = 5420 yen-4430 yen = 990 yen.

  For example, when the reduction cost Ct is positive, the planning unit 42 determines that the alternative plan is more advantageous than the existing plan.

  Note that the planning unit 42 can create an alternative plan that allows a delay in production in the determination regarding the change of the production plan. For example, the planning unit 42 can make an alternative plan that ends the process p shown in the table B11 of FIG. 10 at a time after 24:00.

  In this case, the planning unit 42 calculates the reduction cost Ct in consideration of the cost caused by the end of the entire process being delayed compared to the existing plan.

  Referring to FIG. 4 again, the planning unit 42 outputs information indicating the result of the above determination regarding the change of the production plan to the achievement determining unit 43. The planning unit 42 also outputs alternative plan information indicating the contents of the alternative plan to the control information creating unit 46.

  The achievement determination unit 43 receives information indicating the result of the determination regarding the change of the production plan from the planning unit 42, and determines whether or not the target indicated by the instruction information is achieved based on the information. For example, the achievement determination unit 43 determines whether or not to achieve the power saving target by changing the production plan from the existing plan to the alternative plan based on the reduction cost Ct.

  Specifically, for example, when the reduction cost Ct falls below a predetermined threshold, the achievement determination unit 43 determines that it is not necessary to achieve the power saving target until the production plan is changed.

  If the achievement determination unit 43 determines that the power saving target cannot be achieved, the achievement determination unit 43 transmits to the power consumption management apparatus 201 instruction response information indicating that it does not participate in the power saving event indicated by the instruction information.

  On the other hand, for example, when the reduction cost Ct is equal to or greater than the predetermined threshold, the achievement determination unit 43 determines that the power saving target can be achieved by changing the production plan.

  If the achievement determining unit 43 determines that the power saving target can be achieved, the achievement determining unit 43 transmits instruction response information indicating participation in the power saving event indicated by the instruction information to the power consumption management apparatus 201. In addition, when transmitting the instruction response information to participate in the power saving event, the achievement determining unit 43 includes the reduction amount information indicating the amount of power scheduled to be reduced at the power demand facility 7 in the power saving period in the instruction response information. To send.

  When the participation information acquisition unit 44 receives the aggregator participation information from the power consumption management apparatus 201, the participation information acquisition unit 44 outputs the aggregator participation information to the control information creation unit 46.

  Upon receiving the aggregator participation information from the participation information acquisition unit 44, the control information creation unit 46 controls each production facility 303 according to the contents of the alternative plan information received from the planning unit 42.

  Specifically, the control information creation unit 46 creates substitute control information for controlling each production facility 303 based on the substitute plan information, and transmits the substitute control information to the consumer device 301. The consumer device 301 controls each production facility 303 based on the alternative control information received from the control information creation unit 46.

  More specifically, the system-side management apparatus 101 predicts the overall power demand using, for example, a known demand prediction technique, specifically using a technique such as a neural network or autoregressive analysis. Or the system side management apparatus 101 calculates the average value of the power consumption for Y days except the special day from the data of the power consumption for the past X days, for example.

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

  Next, the transaction market apparatus 401 transmits transaction price information to the power consumption management apparatus 201 (step S12).

  Next, the power consumption management device 201 creates instruction information related to the power consumption of the power demand facility 7 based on the power consumption information received from the system side management device 101. In addition, the power consumption management device 201 displays compensation information indicating the compensation for reducing power consumption in the power demand facility 7 based on the incentive information received from the system side management device 101 and the transaction price information received from the transaction market device 401. create. Then, the power consumption management apparatus 201 transmits the created instruction information and consideration information to the production management apparatus 302.

  Here, the power consumption management device 201 transmits instruction information and consideration information to the production management device 302A that is the production management device 302 in the power demand facility 7A and the production management device 302B that is the production management device 302 in the power demand facility 7B. (Step S13 and Step S14).

  Note that the content of the instruction information transmitted from the power consumption management apparatus 201 to the production management apparatus 302A and the content of the instruction information transmitted to the production management apparatus 302B may be the same or different. Further, the content of the consideration information transmitted from the power consumption management apparatus 201 to the production management apparatus 302A and the content of the consideration information transmitted to the production management apparatus 302B may be the same or different.

  Moreover, the power consumption management apparatus 201 acquires the latest transaction price information from the transaction market apparatus 401 regularly or irregularly, and updates the consideration information based on the acquired transaction price information. Consideration information, that is, latest compensation information may be transmitted to the production management apparatus 302A and the production management apparatus 302B.

  Next, the production management apparatus 302A receives the instruction information and the consideration information from the power consumption management apparatus 201, and makes a determination on the change of the production plan based on the received instruction information and the consideration information (Step S15).

  For example, the production management apparatus 302A determines whether or not the power saving target indicated by the instruction information can be achieved even when the power demand facility 7A performs production according to the existing plan.

  If the production management apparatus 302A determines that the power saving target cannot be achieved if production is performed in accordance with the existing plan, for example, the production management device 302A creates an alternative plan based on various information stored in its own storage unit 45.

  The production management apparatus 302A determines whether or not the power saving target can be achieved by performing production according to the planned alternative plan. Note that the production management apparatus 302A may determine the types and periods of processes included in the alternative plan so that the alternative plan becomes a production plan that can achieve the power saving target.

  In addition, the production management apparatus 302A determines how much merit is obtained when production is performed according to the planned alternative plan. Specifically, for example, the production management apparatus 302A determines a monetary merit based on the reduction cost Ct when production is performed according to the planned alternative plan.

  Next, based on the results of each of the above determinations, the production management apparatus 302A determines whether or not the target indicated by the instruction information can be achieved, for example, whether or not the production plan is changed from the existing plan to the alternative plan to achieve the power saving target. Judgment is made (step S16).

Specifically, the power consumption management apparatus 201 determines whether or not the requested target indicated by the power consumption information can be achieved based on the reduction amount information included in the received instruction response information.

  When the power consumption management apparatus 201 determines that the requested target can be achieved, the power consumption management apparatus 201 transmits request response information indicating that it participates in the power saving event indicated by the power consumption information to the grid side management apparatus 101 (step S22).

  For example, the power consumption management apparatus 201 makes the determination at a time before a predetermined time when the request period indicated by the power consumption information starts.

  Note that the production management apparatus 302 can change the determination as to whether or not its own power demand facility 7 participates in the power saving event until the time comes. For example, when the power consumption management apparatus 201 transmits the latest consideration information to the production management apparatus 302 regularly or irregularly, the production management apparatus 302 determines whether to participate or not participate based on the received latest consideration information. You can review it. In this case, the production management apparatus 302 transmits instruction response information whose contents have been changed to the power consumption management apparatus 201.

  When the power consumption management device 201 determines that the requested power consumption reduction amount has been secured based on the reduction amount information included in the received instruction response information, the power consumption management device 201 sends a power saving event to the system side management device 101. Request response information for participation may be transmitted.

  Further, when the power consumption management apparatus 201 determines to participate in the power saving event, the power consumption management apparatus 201 transmits aggregator participation information to the production management apparatus 302A that is the production management apparatus 302 that has transmitted instruction response information to participate in the power saving event to itself. (Step S23).

  The production management apparatus 302A receives the aggregator participation information from the power consumption management apparatus 201, creates substitution control information for controlling the production facility 303 based on the substitution plan, and the consumer apparatus 301A in the power demand facility 7A. (Step S24).

  The consumer device 301A receives the substitute control information from the production management device 302A, and controls the production facility 303 in the power demand facility 7A based on the received substitute control information (step S25).
