It is when it is judged that it participates.

  For example, even if it is determined that the production management apparatus 302 participates in the power saving event, if the power consumption management apparatus 201 determines not to participate in the power saving event, the power demand facility 7 in which the production management apparatus 302 is installed I can not participate in power saving events.

  The power consumption management apparatus 201 is not limited to the configuration directly connected to the grid-side management apparatus 101, each production management apparatus 302, and the transaction market apparatus 401, but may be connected via another apparatus. .

  FIG. 3 is a diagram showing the configuration of the power consumption management device according to the first embodiment of the present invention.

  Referring to FIG. 3, the power consumption management apparatus 201 includes a request response notifying unit 51, a participation determining unit 52, an instruction response acquiring unit 53, a consumption information acquiring unit 54, an instruction creating unit 55, and an instruction notifying unit. 56 includes a reward information acquisition unit 57, a consideration information creation unit 58, a market information acquisition unit 59, a consideration information notification unit 60, and a participation notification unit 61.

  The consumption information acquisition unit 54 acquires power consumption information related to power consumption from the power system side 5. Specifically, the consumption information acquisition unit 54 receives the power consumption information transmitted from the grid side management apparatus 101 and outputs the information to the instruction creation unit 55 and the participation determination unit 52.

  Instruction creating unit 55 creates instruction information on power consumption in power demanding facility 7 based on the power consumption information received from consumption information acquiring unit 54, and outputs the instruction information to instruction notifying unit 56.

  The instruction notification unit 56 transmits the instruction information received from the instruction creating unit 55 to the production management device 302 that creates a production plan for the power demand facility 7. The contents of the instruction information transmitted to each production management device 302 may be the same or different.

  The reward information acquisition unit 57 receives the incentive information from the grid-side management device 101 and outputs the incentive information to the consideration information creation unit 58.

  The market information acquisition unit 59 receives the transaction price information from the transaction market apparatus 401 and outputs it to the consideration information creation unit 58. For example, the market information acquisition unit 59 periodically or irregularly receives transaction price information from the transaction market apparatus 401 and outputs it to the consideration information creation unit 58.

  The consideration information creation unit 58 creates consideration information based on the incentive information received from the reward information acquisition unit 57 and the transaction price information received from the market information acquisition unit 59, and outputs the consideration information to the consideration information notification unit 60. The consideration information creating unit 58, for example, updates the consideration information each time new transaction price information is received from the market information acquisition unit 59, and outputs the updated consideration information to the consideration information notifying unit 60.

  The consideration information notification unit 60 acquires, from the instruction notification unit 56, information indicating the customer device 301 as a transmission destination of the instruction information. Then, the consideration information notifying unit 60 transmits the consideration information received from the consideration information creating unit 58 to the customer device 301 to which the instruction notifying unit 56 has transmitted the instruction information.

  The instruction response acquisition unit 53 receives the instruction response information from each customer device 301 of the transmission destination of the instruction information, and outputs the instruction response information to the participation determination unit 52.

  The participation determination unit 52 determines whether or not its aggregator 6 participates in the power saving event. Specifically, based on the power consumption information received from the consumption information acquisition unit 54 and each instruction response information received from the instruction response acquisition unit 53, the participation determination unit 52 participates in the power saving event indicated by the power consumption information Judge whether or not.

  More specifically, the participation determination unit 52 determines, for example, the total value of the power consumption to be reduced by each power demand facility 7 in the request period based on the reduction amount information included in each instruction response information. If the total value satisfies the request target, it is determined to participate in the power saving event.

  In addition, the participation determination unit 52 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 51. When outputting the request response information indicating participation in the power saving event to the request response notification unit 51, the participation determination unit 52 outputs the request response information including the reduction amount total information.

  When the participation determination unit 52 determines to participate in the power saving event, the participation determination unit 52 outputs aggregator participation information indicating that the aggregator 6 participates in the power saving event to the participation notification unit 61.

  The request response notification unit 51 transmits the request response information received from the participation determination unit 52 to the grid side management apparatus 101.

  The participation notification unit 61 transmits the aggregator participation information received from the participation determination unit 52 to the production management device 302 provided in the power demand facility 7 participating in the power saving event.

  FIG. 4 is a diagram showing the configuration of a production management device according to the first embodiment of the present invention.

  Referring to FIG. 4, the production management device 302 includes an instruction acquisition unit 41, a planning unit 42, an achievement determination unit 43, a participation information acquisition unit 44, a storage unit 45, and a control information creation unit 46. .

  The planning unit 42 creates a production plan for the power demand facility 7 based on various information stored in the storage unit 45, for example.

  The storage unit 45 stores, for example, various types of information necessary for creating a production plan, such as facility information, production request information, production procedure information, and existing plans. The facility information is, for example, information indicating the type, the number, the power consumption, and the like of the production facility 303 installed in the power demand facility 7. The production requirement information is, for example, information indicating the type, quantity, and delivery date of a product to be produced. The production procedure information is, for example, information indicating the production process of the product and the type of the production facility 303 used in each process.

  The instruction acquisition unit 41 acquires instruction information on power consumption in the power demand facility 7. Specifically, the instruction acquisition unit 41 acquires the instruction information transmitted from the power consumption management device 201 and outputs the instruction information to the planning unit 42 and the achievement determination unit 43.

  In addition, the instruction acquisition unit 41 acquires consideration information indicating the consideration for reduction of the power consumption in the power demand facility 7 transmitted from the power consumption management apparatus 201 and outputs the information to the planning unit 42.

  The planning unit 42 makes a determination regarding the change of the production plan based on the instruction information received from the instruction acquiring unit 41 and the various information stored in the storage unit 45.

  Specifically, for example, the planning unit 42 determines whether or not the power saving target can be achieved even when the production is performed according to the existing plan. If it is determined that the power saving target can not be achieved if the production is performed according to the existing plan, the planning unit 42 determines the production process and period to be implemented so that the power saving target can be achieved, and the judgment result Develop an alternative plan based on

  Furthermore, based on, for example, the instruction information, the consideration information, and the various information stored in the storage unit 45, the planning unit 42 makes a determination regarding the change of the production plan. Specifically, for example, the planning unit 42 determines how much merit is provided when the production is performed according to the prepared alternative plan. The determination is made, for example, based on the increase and decrease of the electricity charges in the power demand facility 7 by changing the production plan from the existing plan to the alternative plan, and the compensation for the power saving acquired by participating in the power saving event.

[Specific example 1]
FIG. 5 is a diagram showing an example of an arrow diagram of an existing plan formulated by the planning unit in the production management device according to the first embodiment of the present invention. FIG. 6 is a view showing an example of a Gantt chart of the existing plan formulated by the planning unit in the production management device according to the first embodiment of the present invention.

  Referring to FIG. 5, arrows a to g indicate steps a to g, respectively. The numerals 10, 20, 30, 40, 50, 60 and 70 represent the divisions between the steps. The numbers in the rectangular frame represent the time required for each process, and the upper case alphabet in the frame represents the production facility 303 used in each process. For example, "A" represents the production facility 303A, and "B" represents the production facility 303B.

  In FIG. 5, for example, the product of step a is processed into different products in steps b, c, d and steps e, f, g, and the product of step d and the product of step g are used to produce a product Show that it will be completed.

  The routes of steps a, e, f, g represented by thick arrows represent critical paths. Also, 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 compared to the routes of the processes e, f and g included in the critical path.

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

  From this, if the steps b, c and d can be ended at the time until the steps e, f and g end, for example, even if the period for performing the steps b, c and d is delayed, the whole steps There is no delay.

  Therefore, for example, by performing steps b, c and d in a period other than the power saving period indicated by the instruction information, it is possible to reduce the power consumption of the power demand facility 7 in the power saving period.

  Referring to FIG. 6, table B1 shows the power consumption of production facility 303 used and production facility 303 during the period when each process shown in FIG. 5 is performed in the existing plan.

  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 power used by the 303E is 40 kW, the power used by the production facility 303F is 50 kW, and the power used by the production facility 303G is 10 kW.

  In the existing plan, the process a is performed using the production facility 303A between 0 o'clock and 5 o'clock as the process in the critical path, and the process e is performed using the production facility 303E between 5 o'clock and 10 o'clock. The process f is performed using the production facility 303F between 10 o'clock and 18 o'clock, and the process g is performed using the production facility 301G between 18 o'clock and 24 o'clock.

  Also, in the existing plan, as a process in a route other than the critical path, the process b is performed using the production facility 303B between 5 o'clock and 8 o'clock, and the production facility 303C is used between 8 o'clock and 11 o'clock The process c is performed, and the process d is performed using the production facility 303D from 11 o'clock to 14 o'clock.

  FIG. 7 is a view showing an example of a Gantt chart of an alternative plan prepared by the planning unit in the production management device according to the first embodiment of the present invention.

  Referring to FIG. 7, table B2 shows the power consumption of production facility 303 used and production facility 303 during the alternative plan, during the time when each process shown in FIG. 5 is performed. A power saving period is between 8 o'clock and 13 o'clock.

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

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

  The planning unit 42 may also design an alternative plan in which the processes b, c, and d are not performed continuously. Specifically, for example, the planning unit 42 performs the process b between 5 o'clock and 7 o'clock, and performs the process b between 13 o'clock and 16 o'clock, and the process d from 19 o'clock to 22 o'clock. An alternative plan to be implemented between the two may be formulated.

  When the planning unit 42 drafts an alternative plan, it next determines how much merit it will be if 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 showing 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 is power consumption P1 which is power consumption per hour when each process is performed according to the existing plan, that is, table B1 shown in FIG. 6, and alternative plan is table B2 shown in FIG. The power consumption P2 which is the power consumption for every hour in, when each process is implemented according to is shown.

  Table B3 also shows electricity unit price U, which is the unit price of electricity charges per hour, electricity rates M1, which is the electricity charges per hour when each process is carried out according to the existing plan, and each process according to the alternative plan. An electricity bill M2 is shown which is an electricity bill per hour when it is carried out.

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

  Table B3 also shows the amount of reduced power D, which is the amount of power consumption that is reduced when the production plan is changed from the existing plan to the alternative plan, on an hourly basis, and the price that is the unit price of the power saving compensation shown in the compensation information. A unit price Q and a power saving consideration T which is a price for power saving that can be obtained when production is performed according to the alternative plan is shown.

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

  Table B3 shows the total value of power consumption P1, the total value of power consumption P2, the total value of electricity charges M1, the total value of electricity charges M2, and the total value of power saving consideration T from 0 o'clock to 24 o'clock. .

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

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

  Then, the planning unit 42 calculates a reduction cost Ct, which 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 rates 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 arrow diagram of an existing plan formulated by the planning unit in the production management device according to the first embodiment of the present invention. FIG. 10 is a diagram showing an example of a Gantt chart of the existing plan formulated by the planning unit in the production management device according to the first embodiment of the present invention.

  Referring to FIG. 9, arrows m to p represent steps m to p, respectively. The numerals 10, 20, 30, 40, and 50 represent the separation of the process and the process. The numbers in the rectangular frame represent the time required for each process, and the upper case alphabet in the frame represents the production facility 303 used in each process. For example, "A" represents the production facility 303A, and "B" represents the production facility 303B.

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

  Referring to FIG. 10, table B11 shows the power consumption of production facility 303 used and production facility 303 during the period when each process shown in FIG. 9 is performed in the existing plan.

  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 power used by the 303E is 50 kW, and the 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 between 0 o'clock and 5 o'clock, and the process n is performed using the production facility 303B between 5 o'clock and 10 o'clock The process o is performed using the production facility 303C between 10 o'clock and 18 o'clock, and the process p is performed using the production facility 303D between 18 o'clock and 24 o'clock.

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

  Referring to FIG. 11, a table B12 shows the power consumption of the production facility 303 used and the production facility 303 during the alternative planning, during the time when each process shown in FIG. 9 is performed. Between 8 o'clock and 12 o'clock is a power saving period.

  The planning unit 42 prepares an alternative plan shown in FIG. 11 based on the instruction information and the various information stored in the storage unit 45. In the alternative plan, the process is not performed between 8:00 and 13:00 which is a power saving period.

  Specifically, in the alternative plan, the process m is performed using the production facility 303A between 0 o'clock and 5 o'clock, and the process n1 is performed using the production facility 303B between 5 o'clock and 8 o'clock The process n2 is performed between 6 o'clock and 8 o'clock using the production facility 303E.

  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 process n of the existing plan. Process n2 corresponds to the process from 8 o'clock to 10 o'clock in process n of the existing plan.

  In the alternative plan, the process o1 is performed using the production facility 303C between 13:00 and 18:00, and the process o2 is performed using the production facility 303F between 13:00 and 16:00 at 18:00. The process p is carried out using the production facility 303D from 2:00 to 24:00.

  Steps o1 and o2 correspond to step o in the existing plan shown in FIG. Specifically, the process o1 corresponds to the process from 10 o'clock to 15 o'clock in the process o of the existing plan, and the process o2 corresponds to the process from 15 o'clock to 18 o'clock in the process o of the existing plan.

  Thus, in the alternative plan, power consumption at the power demand facility 7 is reduced by not using the production facility 303 between 8:00 and 13:00, which is a power saving period.

  When the planning unit 42 drafts an alternative plan, it next determines how much merit it will be if 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 showing 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 merits of the alternative plan.

  Referring to FIG. 12, table B13 is power consumption P11, which is power consumption per hour in the case where each step is performed according to the existing plan, that is, table B11 shown in FIG. Power consumption P12 which is power consumption for every hour in, when each process is implemented according to is shown.

  Table B13 also includes electricity unit price U1, which is the unit price of electricity charges per hour, electricity rates M11, which is the electricity charges per hour when each process is performed according to the existing plan, and each process according to the alternative plan. An electricity bill M12 is shown, which is an electricity bill per hour when it is carried out.

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

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

  A power saving period is between 8 o'clock and 13 o'clock. Here, it is assumed that in the power saving period, a price for power saving is generated, and in a period other than the power saving period, a price for power saving is not generated. That is, in the power saving period, the unit price Q1 is set. The reduced power amount D1 is obtained by the difference between the power consumption P11 and the power consumption P12. The power saving consideration T1 is obtained by the product of the reduction amount D1 and the unit price Q1.

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

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

  Here, the cost generated by performing the production according to the alternative plan, for example, the cost R1 generated by operating the production facility 303E and the production facility 303F which are not normally operated, is 2000 yen.

  The planning unit 42 obtains, for example, a substantial electricity bill Ma12 required when each process is performed according to the alternative plan by adding the expense R1 to the difference between the sum of the electricity bill M12 and the sum of the power saving consideration T1. . Specifically, the electricity charge Ma12 = 7430 yen-5000 yen + 2000 yen = 4430 yen.

  Then, the planning unit 42 calculates a reduction cost Ct, which 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 rates 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.

  In addition, the planning unit 42 can create an alternative plan in which production delay is allowed in the judgment on the change of the production plan. For example, the planning unit 42 can create an alternative plan that ends the process p shown in the table B11 of FIG. 10 at a time after 24 o'clock.

  In this case, the planning unit 42 calculates the reduction cost Ct in consideration of the cost generated by delaying the end of the whole process compared to the existing plan.

  Referring back to FIG. 4, the planning unit 42 outputs information indicating the result of the above-mentioned judgment on the change of the production plan to the achievement judging unit 43. Further, the planning unit 42 outputs, to the control information creation unit 46, alternative plan information indicating the contents of the alternative plan.

  The achievement judging unit 43 receives information indicating the result of the judgment on the change of the production plan from the planning unit 42, and judges whether the target indicated by the instruction information can be achieved based on the information. For example, based on the reduction cost Ct, the achievement determination unit 43 determines whether to change the production plan from the existing plan to the alternative plan and achieve the power saving target.

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

  When determining that the power saving target can not be achieved, the achievement determining unit 43 transmits, to the power consumption management apparatus 201, instruction response information indicating that the user does not participate in the power saving event indicated by the instruction information.

  On the other hand, when the reduction cost Ct is equal to or more than the predetermined threshold value, for example, the achievement determining unit 43 determines that the production plan can be changed to achieve the power saving target.

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

  When the participation information acquisition unit 44 receives the aggregator participation information from the power consumption management device 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 generation 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 alternative control information for controlling each production facility 303 based on the alternative plan information, and transmits the alternative control information to the customer device 301. The customer device 301 controls each production facility 303 based on the substitute control information received from the control information creation unit 46.

[Operation]
Next, an operation when the power consumption management system according to the first embodiment of the present invention performs a power consumption reduction process will be described.

  Each device in the power consumption management system includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including some or all of the steps of the following flowchart and sequence from a memory (not shown). The programs of the plurality of devices can be installed from the outside. The programs of the plurality of apparatuses are distributed as stored in the recording medium.

  FIG. 13 is a diagram showing an example of a sequence of power consumption reduction processing in the power consumption management system according to the first embodiment of the present invention.

  Referring to FIG. 13, first, grid-side management apparatus 101 predicts, for example, the power demand on the next day, and determines that power consumption should be suppressed if there is a high possibility that the power supply-demand balance will be tight (Step S10).

  More specifically, the grid-side management device 101 predicts the overall power demand using, for example, a known demand prediction technology, specifically using a technology such as a neural network or an autoregression analysis. Alternatively, the grid management device 101 calculates, for example, the average value of the power consumption for Y days excluding the specific day from the data of the power consumption for the past X days.

  Next, the grid-side management device 101 transmits the power consumption information and the incentive information to the power consumption management device 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 apparatus 201 creates instruction information on the power consumption of the power demanding facility 7 based on the power consumption information received from the grid-side management apparatus 101. In addition, the power consumption management device 201 calculates the compensation information indicating the compensation for the reduction of the power consumption at the power demand facility 7 based on the incentive information received from the grid side management device 101 and the transaction price information received from the transaction market device 401. create. Then, the power consumption management device 201 transmits the created instruction information and the consideration information to the production management device 302.

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

  The content of the instruction information that the power consumption management device 201 transmits to the production management device 302A may be the same as or different from the content of the instruction information that is transmitted to the production management device 302B. Further, the content of the consideration information transmitted by the power consumption management device 201 to the production management device 302A and the content of the consideration information transmitted to the production management device 302B may be the same or different.

  In addition, the power consumption management device 201 periodically or irregularly acquires the latest transaction price information from the transaction market device 401, updates the consideration information based on the acquired transaction price information, and updates the value each time the information is updated. The consideration information, that is, the latest consideration information may be transmitted to the production management device 302A and the production management device 302B.

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

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

  When the production management device 302A determines that the power saving target can not be achieved if the production is performed according to the existing plan, the production management device 302A creates an alternative plan, for example, based on various information stored in its own storage unit 45.

  The production management device 302A determines whether the power saving target can be achieved by performing the production according to the prepared alternative plan. The production management device 302A may determine the type and period of the process included in the alternative plan so that the alternative plan is a production plan that can achieve the power saving target.

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

  Next, based on the results of the above judgments, the production management apparatus 302A determines whether the target indicated by the instruction information can be achieved, for example, whether the existing plan is changed from the existing plan to the alternative plan to achieve the power saving target. It judges (step S16).

  Here, the production management apparatus 302A determines that the power saving target can be achieved by changing the production plan from the existing plan to the alternative plan, and instructs the response information indicating participation in the power saving event indicated by the instruction information to the power consumption managing apparatus 201 It transmits to (step S17). The instruction response information is, for example, information based on the determination result on the change of the production plan in step S15.

  On the other hand, the production management device 302B receives the instruction information and the consideration information from the power consumption management device 201, and makes a judgment on the change of the production plan similarly to the production management device 302A based on the received instruction information and the consideration information. (Step S18).

  Next, similarly to the production management device 302A, the production management device 302B determines whether the goal indicated by the instruction information can be achieved, for example, whether the existing plan is changed from the existing plan to the alternative plan and the power saving target is achieved. (Step S19).

  Here, the production management device 302B determines that it is not necessary to achieve the power saving target until the production plan is changed from the existing plan to the alternative plan, and instructs response information indicating that it does not participate in the power saving event indicated by the instruction information. It transmits to the consumption management apparatus 201 (step S20).

  Next, the power consumption management device 201 receives instruction response information from the production management device 302A and the production management device 302B, and determines whether the aggregator 6 participates in the power saving event indicated by the power consumption information (step S21). ). Specifically, based on the reduction amount information included in the received instruction response information, the power consumption management device 201 determines whether the request target indicated by the power consumption information can be achieved.

  If the power consumption management device 201 determines that the request target can be achieved, the power consumption management device 201 transmits request response information indicating participation in the power saving event indicated by the power consumption information to the grid side management device 101 (step S22).

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

  The production management apparatus 302 can change the determination as to whether or not the power demand facility 7 of its own participates in the power saving event until the arrival of the time. For example, when the power consumption management apparatus 201 periodically or irregularly transmits the latest consideration information to the production management apparatus 302, the production management apparatus 302 determines the participation or non-participation based on the received latest consideration information. It can be reviewed. In this case, the production management device 302 transmits, to the power consumption management device 201, the instruction response information whose content has been changed.

  When it is determined that the requested reduction amount of power consumption 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 grid-side management device 101. A request response information to participate may be transmitted.

  Also, when judging that the power consumption management apparatus 201 participates in the power saving event, the power consumption management apparatus 201 transmits aggregator participation information to the production management apparatus 302A which is the production management apparatus 302 that has sent instruction response information indicating participation in the power saving event to itself. (Step S23).

  The production management device 302A receives the aggregator participation information from the power consumption management device 201, and creates substitution control information for controlling the production facility 303 based on the substitution plan, and the customer device 301A in the power demand facility 7A. It transmits to (step S24).

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

  By the way, since each production process is performed in accordance with a formulated production plan in a factory or the like, it may be difficult to save power even when tight power supply and demand are expected.

  On the other hand, in the power consumption management system according to the first embodiment of the present invention, the power consumption management device 201 manages the power consumption in the power demand facility 7.
