  The operation unit 107 is configured to include various operation buttons and the like, generates operation information corresponding to an operation from the user, and supplies the operation information to the control unit 101.

  As illustrated in FIG. 3, each electrical device 20 includes a control unit 201, a storage unit 202, various elements 203, and a communication unit 204.

  The control unit 201 controls the electric device 20 and particularly performs processing described later.

  The various elements 203 operate under the control of the control unit 201, and the specific contents differ depending on what the electric device 20 is.

It includes a heater part such as a coil to be heated.

  When the control unit 201 controls various elements 203 to operate, the electrical device 20 operates as a home appliance. In addition, the control unit 201 performs processing described later.

  The communication unit 204 is connected to the device control network N1 and mediates communication between the control unit 201 and the power control apparatus 10. That is, the control unit 201 communicates with the power control apparatus 10 via the communication unit 204.

  Next, processing performed by the control unit 101 of the power control device 10 and the control unit 201 of the electric device 20, a data table stored by the storage unit 102 of the power control device 10 and the storage unit 202 of the electric device 20 will be described.

  Here, in this embodiment, a period is set. This period may be set in advance assuming the user's life rhythm or life scene, or the user operates the operation unit 107 of the power control apparatus 10 to set (the following data table) May be recorded).

  In the present embodiment, as the period, the winter (November to February) characterizing the user's life scene is a weekday (any Monday to Friday other than a national holiday) morning (6:00 to 10:00), summer (July To September) are set for holidays (including Saturday) noon (11:00 to 14:00) and summer holiday evenings (18:00 to 22:00). As described above, a plurality of periods are set. The division and number of the above periods are appropriately changed according to the embodiment.

  In the present embodiment, information indicating the total power consumption sequentially supplied from the power sensor 40 is accumulated in the storage unit 102 (for example, the past one month is accumulated). This is performed by the recording unit 101k. The recording unit 101k sequentially records the information indicating the total power consumption in the recording unit 101k via the second communication unit 105 together with the information indicating the current date and time as the history of the total power consumption ( (See FIG. 4). Note that the date and time at that time means the date and time when the total power consumption is measured (hereinafter referred to as the measurement date and time). When the recording unit 101k acquires information indicating the total power consumption, the calendar unit Information indicating the date and time is acquired from the information 106, and the information indicates the measurement date and time of the acquired information.

In addition, the storage unit 102 stores data tables 1 to 3.
The data table 1 is a table in which information representing the plurality of types of periods and information representing the conditions of each period are recorded in association with each other (see FIG. 5).

  The data table 2 is a table in which information representing the plurality of types of periods and information representing predicted values for each period are recorded in association with each other (see FIG. 6). The predicted value is a predicted value for the total power consumption of the power control system 1 in each period, and here is a pattern of the maximum amount of change (including an increase) in power consumption in that period. That is, the predicted value is a value obtained by subtracting the total power consumption before the period from the maximum total power consumption during the period (see also FIG. 7). This predicted value is preset in consideration of the rule of thumb and the average power consumption for each household period, or is calculated from the total power consumption in the same period in the past (that is, measured in the same type of period in the past). Further, it may be learned based on information indicating the total power consumption.

  When calculating the predicted value from the total power consumption in the same past period, for example, the recording unit 101k refers to the history of the total power consumption recorded in the storage unit 102 at a predetermined timing, and in the same period P1 in the past. The amount of change in power consumption, which is obtained by subtracting the average value B of the total power consumption at the timing within the range P2 retroactive from the start of this period P1 from the maximum total power consumption A, is calculated as the predicted value C for that period. (See FIG. 7), recorded in the data table 1. Further, for example, the recording unit 101k may calculate the calculated predicted value for a plurality of periods, take an average of the calculated predicted values, and record the average value in the data table 1 as the period predicted value. .

  The data table 3 represents the information representing the plurality of types of periods, the information representing the electrical equipment 20 (assumed operating equipment) that is likely to be operating in each period, and the control contents in each period. It is a table in which information is recorded in association with each other. The control content is determined in advance according to each period, and information indicating the control content is recorded in the data table 3 in advance. The control content indicates one or more control objects and control timings that are determined in advance in consideration of what kind of electrical equipment 20 is used in each period. That is, the control content suppresses the power consumption of the electrical device 20 and the electrical device 20 determined to suppress the power consumption from the one or more electrical devices 20 expected to be used by the user in each period. One or a plurality of timings are indicated. In other words, the control content designates one or more electrical devices 20 for which power consumption is to be suppressed and the timing of suppression. That is, for the electrical device 20 specified by this control content, an attempt is made to suppress power consumption at the specified timing. FIG. 8 shows an example of the data table 3. In addition, since the life pattern of the normal user is determined, the user often uses the same behavior, that is, the same electric device 20 in the same usage method during the same type of period. In the present embodiment, paying attention to such points, the control content is determined for various periods.

  For example, when the period is “winter weekday morning”, it is assumed that the user warms the room by the air conditioner 24 and makes breakfast by the microwave oven 23 or the IH cooking heater 22 within this period. For this reason, if the air conditioner 24 and the IH cooking heater 22 are used at the same time, the total power consumption of each electrical device 20 will increase. Therefore, before the predetermined time in this period (here, 6:30), first, the power consumption of the IH cooking heater 22 is suppressed, and the power consumption of the air conditioner 24 is suppressed after the predetermined time. The peak of the power consumption is shifted to prevent the total power consumption at a certain time from increasing. In order to perform such control, in the control content here, for the suppression timing before 6:30, the IH cooking heater 22 is designated as the electrical device 20 whose power consumption is to be suppressed, and the suppression timing after 6:30 The air conditioner 24 is designated as the electric device 20 whose power consumption is to be suppressed.

  For example, when the period is “summer holiday noon”, the user cools the room with the air conditioner 24 during this period and uses, for example, a microwave oven 23 to prepare for lunch, It is assumed to watch TV. In this case, since the user may feel uncomfortable when the cooling set temperature is increased in order to suppress the power consumption of the air conditioner 24, the microwave oven 23 is designated by the control content, and the power consumption of the microwave oven 23 is determined. By suppressing the above, even if the cooking time of the microwave oven 23 is somewhat longer, the set temperature of the cooling is maintained. Thereby, the total power consumption of each electrical device 20 is suppressed.

  For example, when the period is “summer holiday evening”, the user cools the room with the air conditioner 24 during this period and uses the IH cooking heater 22 to prepare dinner, for a bath or the like. It is assumed that the electric water heater 26 is used and the television is viewed. In this case, since it is considered that the temperature is getting lower in the summer evening, even if the power consumption is suppressed by increasing the set temperature of the cooling in order to suppress the power consumption of the air conditioner 24, It is considered that the user does not feel uncomfortable. In addition, since the amount of hot water used for bathing is relatively small on summer evenings, the electric water heater 26 is designated as an object to be controlled so as to suppress power consumption according to the control content. That is, by suppressing the power consumption of the air conditioner 24 and the electric water heater 26, the total power consumption of each electric device 20 is suppressed.

  The contents of the data table 2 can be appropriately changed to information input from the operation unit 107 by the user operating the operation unit 107. In particular, the user can set the above-described control contents to improve convenience. For example, in the period “summer holiday evening”, a case will be described as an example where it is desired not to lower the set temperature set in the air conditioner 24 in order to improve sleep. In this case, the user operates the operation unit 107 to display information indicating the period “summer holiday evening” and information indicating the control content in which the air conditioner 24 is not designated as a target whose power consumption is suppressed. Is input to the power control apparatus 10. After that, the power control apparatus 10 records the information indicating the input period and the information indicating the control content in the data table 2 in association with each other. According to this configuration, the power control apparatus 10 does not perform power consumption suppression control on the air conditioner 24 excluded from the power consumption suppression target by the user, but the user does not exclude it from the power consumption suppression target. Since the power consumption suppression control is executed for the electric device 20, the total power consumption of the power control system 1 can be suppressed while preventing the user's convenience of the electric device 20 from being lowered.

  The control unit 101 of the power control apparatus 10 illustrated in FIG. 2 performs power control processing using the specifying unit 101a and the like. Also, the control unit 201 of the electrical device 20 illustrated in FIG. 3 performs a process in response to a power consumption suppression instruction transmitted with the execution of the power control process by the control unit 101. These processes are started simultaneously with the start of the operation of the power control device 10 and each electric device 20, and are always performed while the power control device 10 and each electric device 20 are in operation. Note that the recording of the power consumption history by the recording unit 101k of the control unit 101 shown in FIG. 2 is performed in parallel with this processing.

  When the execution of the power control process shown in FIG. 9 is started, the identifying unit 101a refers to the calendar unit 106 in FIG. 2 in step S101, and whether the period recorded in the data table 1 in FIG. Is discriminated (step S101).

  For example, the specifying unit 101a acquires the current date and time information supplied from the calendar unit 106, and the time after a predetermined time (for example, 10 minutes later) from the acquired current date and time is shown in FIG. A search is performed as to whether any of the conditions in the data table 1 in FIG. If there is a condition that is applicable, the period associated with the condition is specified as the period to come. When the period is specified, the period arrives after the predetermined time elapses. Therefore, the specifying unit 101a determines that the period recorded in the data table 1 has arrived (step S101; YES). In the present embodiment, in this way, the specifying unit 101a determines the time period that will be reached from among the set types of time periods based on the current date and time information supplied from the calendar unit 106. Identify. For example, if the current time is Wednesday, November 16, and the time is 5:50 am, the specifying unit 101a specifies “winter weekday morning” as the period and is recorded in the data table 1. It is determined that a certain period has arrived.

  On the other hand, if the period is not specified, the specifying unit 101a determines that the period has not come (step S101; NO), and performs the process of step S101 again. That is, the control unit 101 waits until the period recorded in the data table 1 comes in the near future.

  If the identification unit 101a determines YES in step S101, the predicted value acquisition unit 101b refers to the data table 2 of FIG. 6 and corresponds to this period using the period coming from the identification unit 101a identified as a key. The predicted value of the change amount of the total power consumption is acquired from the storage unit 102 (step S102). For example, if “winter weekday morning” is specified by the specifying unit 101a, the predicted value acquiring unit 101b uses X [kW] as the predicted value associated with this in the data table 2 of FIG. get. In the present embodiment, in this way, the predicted value acquisition unit 101b changes the pattern associated with the period specified by the specifying unit 101a from the storage unit 102, and the amount of change in the total power consumption during the coming period. Get as the predicted value of.

  When the predicted value acquisition unit 101b acquires the predicted value, the current value acquisition unit 101c acquires the current value of the total power consumption in the power control system 1 for the power supplied from the power system 99 (step S103). For example, the current value acquisition unit 101c waits for the predetermined time from the time supplied from the calendar unit 106 (that is, waits for the period specified above to start), and at that time (for example, Just before the start), the history of the total power consumption recorded in the storage unit 102 is referred, and a certain period (for example, 30 minutes) is traced back from the start of the period specified above (see P3 in FIGS. 10 and 11). The current value of the total power consumption is obtained by calculating the average value of the total power consumption at the timing within the range (see P4 in FIGS. 10 and 11) as the current value of the total power consumption. The current value of the total power consumption may be, for example, the latest total power consumption at that time or when the predetermined time has elapsed. In this case, the current value acquisition unit 101 c acquires the latest total power consumption as the current value from the storage unit 102 or the second communication unit 105.

  When the current value acquisition unit 101c acquires the current value of the total power consumption, the calculation unit 101d changes the current value of the total power consumption acquired by the current value acquisition unit 101c and the amount of change in the total power consumption acquired by the predicted value acquisition unit 101b. Based on the predicted value, the predicted power (for example, the predicted value of the total power consumption) for the total power consumption in the period specified above is calculated (step S104).

  For example, the predicted power is the sum of the current value of the total power consumption and the predicted value of the change amount of the total power consumption (see FIGS. 10 and 11). 10 and 11 show an example of the transition of the total power consumption in the power control system 1 for the power supplied from the power system 99 before and after the current arrival period (the period specified above) P3. FIG. Hereinafter, the incoming period is simply referred to as period P3. Also, the alternate long and short dash line is a line representing the transition of the predicted total power consumption based only on the predicted value, and it is not known how the power consumption actually transitions. The calculation unit 101d calculates the predicted power by adding the current value and the predicted value. Since the predicted value is the amount of the maximum increase during that period, the value obtained by adding the current value of the total power consumption and the predicted value is the value predicted to be the maximum power consumption in this period P3. That is, the predicted power in the present embodiment is a value predicted to be the maximum total power consumption in this period P3.

  As described above, since the life pattern of the normal user is determined, the user often uses the same electrical device 20 in the same usage method during the same period. For this reason, the increase in the total power consumption is likely to be the same in the same period. In the present embodiment, paying attention to such points, the predicted value of the change amount of the total power consumption is set, so that the maximum power consumption in the period P3 can be accurately predicted.

  In step S104 of FIG. 9, when the calculation unit 101d calculates the predicted power, the power control unit 101e determines the predicted power calculated by the calculation unit 101d in advance for the power supplied from the power system 99. Whether or not the threshold value for the total power consumption in 1 is exceeded is determined (step S105). This threshold value is a value that causes inconveniences such as the breaker of the power distribution device 60 falling or the power consumption becoming too large if the total power consumption for the power system 99 exceeds this value, or a predetermined margin from this value. And is set in advance (for example, recorded in the storage unit 102).

  When it is determined that the predicted power does not exceed the threshold (in the case of FIG. 10) (step S105; NO), the power control unit 101e performs the process of step S108. In this case, since the total power consumption in the period P4 is small, even if the method of using the electrical device 20 assumed as described above is used in the period P3 (the period specified by the specifying unit 101a), the total power consumption has a threshold value. It is because it is predicted that there is no problem because it does not exceed.

  On the other hand, if the power control unit 101e determines that the predicted power exceeds the threshold (in the case of FIG. 11) (step S105; YES), the power control unit 101e refers to the data table 3 in FIG. Information representing the control content corresponding to this period is acquired from the storage unit 102 as a key (step S106). For example, when the specifying unit 101a specifies the period “winter weekday morning”, information indicating the control content “before 6:30; IH cooking heater, after 6:30; air conditioner” is acquired.

  When acquiring the information indicating the control content, the power control unit 101e starts control of the electrical device 20 so as to suppress the power consumption of the electrical device 20 in accordance with the control content represented by this information (step S107). In this case, the total power consumption in the power control system 1 for the power supplied from the power system 99 in the period P4 is large, and the way of using the electrical device 20 assumed as described above is made in the period P3. Since the total power consumption exceeds the threshold value, there is a high possibility that inconveniences such as the breaker of the power distribution device 60 falling and the total power consumption becoming too large will occur, and this is suppressed.

  Here, the control process (hereinafter referred to as suppression instruction transmission process) for the electric device 20 started in step S107, and the process performed by the control unit 201 of the electric device 20 in response to this control (hereinafter referred to as suppression instruction response process). ) Will be described with reference to FIG. It is assumed that the electric device 20 starts this process from turning on the power.

  When the suppression instruction transmission process in FIG. 12 is started, the power control unit 101e of the power control apparatus 10 determines whether the suppression instruction transmission process is finished (step S201). For example, the power control unit 101e arrives at the present when all the control specified by the control content acquired in step S106 in FIG. 9 has been completed (the control once performed is not performed again). Since the suppression instruction is not issued again during the period P3, it is determined that the suppression instruction ends (step S201; YES), and this process ends.

  On the other hand, the power control unit 101e determines whether it is the timing of the suppression instruction when all of the control specified by the control content is not completed (step S202). For example, the power control unit 101e determines whether the current time represented by the information supplied from the calendar unit 106 is the control specified by the control content and matches the suppression timing in the control that has not yet been performed. If it is determined that the timing does not coincide with the suppression timing for all the controls, it is determined that the timing is not yet the timing of the suppression instruction (step S202; NO), and the process of step S201 is performed again. In this way, the power control unit 101e waits until the timing of the next suppression instruction.

  On the other hand, for example, the power control unit 101e matches the suppression timing in the control that the current time represented by the information supplied from the calendar unit 106 is specified by the control content and has not yet been performed. If it is, it is determined that it is the timing of the suppression instruction (step S202; YES), and a power consumption suppression instruction is issued to the electrical device 20 corresponding to the matching suppression timing (step S203).

  For example, when the control content is “before 6:30; IH cooking heater, after 6:30; air conditioner” in the data table 3 of FIG. 8 and the current time is 6 o'clock, the current time is 6 The power control unit 101e identifies the IH cooking heater 22 corresponding to the electric device 20 because it matches the suppression timing before half hour. Note that the electrical device 20 for which no suppression timing is specified (for example, “microwave oven” in the data table 3 of FIG. 8) is first identified (that is, the suppression timing of the electrical device 20 is determined as shown in FIG. 9). This is the start time of the period determined to arrive at step S101). When there are a plurality of matching suppression timings, a plurality of electrical devices 20 corresponding to each matching suppression timing are specified (for example, “air conditioner, electric water heater” in the data table 3 in FIG. 8, etc.) ). The power control unit 101e supplies (transmits) information indicating the power consumption suppression value to the identified electrical device 20.

  The power control unit 101e calculates a value obtained by subtracting a threshold value from the predicted power calculated by the calculation unit 101d, or a value obtained by adding a predetermined value to the value to obtain a margin, or the like as a power consumption suppression value. The power control unit 101e supplies this suppression value to the electrical device 20 specified above. Information representing the suppression value is supplied to the electrical device 20 via the first communication unit 104 and the device control network N1. As a result, information representing the suppression value is supplied to the electric device 20.

  When a plurality of electrical devices 20 are specified, a value obtained by dividing the suppression value by the number is supplied to each electrical device 20 as a first suppression instruction, or for example, a preset weight (for example, data In accordance with the control contents of the table 3, the suppression values are distributed to the electric devices 20, and the suppression values are supplied to the electric devices 20 as the first suppression instructions.

  On the other hand, the control unit 201 of the electrical device 20 that has started the suppression instruction response process of FIG. 12 determines whether information representing a suppression value has been received from the power control apparatus 10 via the communication unit 204 (step S301). . When the information indicating the suppression value has not been received (step S301; NO), the control unit 201 performs the process of step S301 again. The control unit 201 waits until receiving information indicating the suppression value.

  When the control unit 201 receives information indicating the suppression value (step S301; YES), the control unit 201 controls the various elements 203 in FIG. 3 according to the suppression value represented by this information and attempts to suppress power consumption (step S302). ).

  Here, a data table referred to in this control is recorded in the storage unit 202. This data table is a table in which a range of power consumption values that can be suppressed (for example, 0.1 kW to 0.2 kW, etc.) and a control method of various elements 203 for obtaining the power consumption that can be suppressed are associated with each other. It is. The control method differs depending on what the electric device 20 is. For example, if the electric device 20 is the IH cooking heater 22, the control method includes a transition to the energy saving mode, suppression of maximum power consumption (suppression from 2.5 kW to 2.0 kW), and the like. In the air conditioner 24, the air conditioner 24 includes a lowering of the set temperature by 1 ° C. for heating and an increase of 1 ° C. for cooling, transition to an energy saving mode, a change in cooling or heating capacity, and the like.

  The range of the power consumption value of the data table 4 is recorded and fixed in the storage unit 202 in advance, or the power consumption when the control unit 201 operates the various elements 203 by the control methods of the data table 4. The measured power consumption may be recorded in the storage unit 202 as a history, and the range may be calculated based on this power consumption history. For example, the average value ± predetermined value of the maximum power consumption in the same control method may be set as the above range, and the range of the maximum value and the minimum value in the maximum power consumption in the same control method may be set as the above range. In addition, once the above range is calculated, the above range may be corrected by a weighted average or the like each time each control method is performed.

  The control unit 201 refers to the data table 4, uses the suppression value as a key, specifies the control method corresponding to the range in which the suppression value falls, acquires it from the storage unit 202, and uses the acquired control method to set the various elements 203. Control (for example, increase the set temperature by 1 ° C.). Note that when a plurality of control methods are specified, the control unit 201 specifies a control method having the largest maximum value in the range (if the maximum value is the same, for example, randomly selects the control method). ).

  After step S302 in FIG. 12, the control unit 201 controls the various elements 203 by the above-described control method, and then calculates power consumption (hereinafter referred to as “suppressed power”) that can be actually suppressed before and after the control. 204 is supplied (returned) to the power control apparatus 10 via 204 and the device control network N1 (step S303), and the above processing is repeated from the processing of step S301.

  Depending on the operation mode of the various elements 203, the various elements 203 may not be controlled by the above-described control method (for example, during cooking with the IH cooking heater 22). In this case, the control unit 201 sets the suppression power to 0 and supplies the suppression power to the power control apparatus 10. Note that the control unit 201 can control the various elements 203 by the control method after the control elements 201 can control the various elements 203 (that is, wait until control can be performed). Good.

  The operation of the control unit 201 as described above is performed for all the electric devices 20 to which the information indicating the suppression value is supplied.

  Information representing the suppressed power supplied to the power control apparatus 10 is received by the receiving unit 101 f via the first communication unit 104. After step S203 of FIG. 12, the power control unit 101e displays information indicating the suppression power (when the suppression value is supplied to the plurality of electrical devices 20, the suppression power from all the electrical devices 20 is represented by the reception unit 101f. When the information) is received, the suppression power represented by this information (when information indicating suppression power is supplied from a plurality of electrical devices 20), the suppression power represented by the information is added to the suppression power. It is determined whether the value is greater than or equal to the value (step S204). When the suppression power is equal to or greater than the suppression value, the maximum power consumption in the period P3 is likely to be equal to or less than the threshold (see FIG. 13). As a result, it is possible to prevent inconveniences such as the breaker of the power distribution device 60 being dropped and the power consumption being excessively large.

  If the suppression power is greater than or equal to the suppression value (step S204; YES), the power control unit 101e returns to step S201 and repeats the above processing. Thereafter, if the control specified by the control content still remains, the remaining control is performed again.

  On the other hand, when the suppression power is less than the suppression value (step S204; NO), the power control unit 101e calculates a value obtained by subtracting the suppression power from the suppression value as a new suppression value, and represents the calculated new suppression value. Is supplied to another electrical device 20 (the electrical device 20 that has not supplied the information indicating the suppression value in step S108) (step S205). One or more electrical devices 20 that supply information representing a new suppression value are selected based on a predetermined rule by the power control unit 101e (for example, main devices that are assumed to be used in the data table 3). 1 or more are randomly selected.

  The description of the processing in step S205 is the same as that in step S203. In addition, the operation of the control unit 201 provided in the other electrical device 20 to which the information indicating the new suppression value is supplied is the same as the processing in steps S301 to S303, and thus detailed description thereof is omitted. As a result, information representing new suppressed power is supplied from the other electrical device 20.

  Information representing new suppressed power supplied to the power control apparatus 10 is received by the receiving unit 101 f via the first communication unit 104. When the power control unit 101e receives information indicating new suppression power (information indicating all new suppression power), the power control unit 101e is expressed by the received information (represented by a plurality of pieces of received information). It is determined whether or not all of the suppression power values are equal to or greater than the suppression value (step S206). When the total value is equal to or greater than the suppression value, the maximum power consumption in the period P3 is likely to be equal to or less than the threshold value as described above. As a result, it is possible to prevent inconveniences such as the breaker of the power distribution device 60 being dropped and the power consumption being excessively large.

  When the total value of the suppression power is equal to or greater than the suppression value (step S206; YES), the power control unit 101e returns to step S201 and repeats the above process. Thereafter, if the control specified by the control content still remains, the remaining control is performed again.

  On the other hand, when the total value of the suppression power is less than the suppression value (step S206; NO), the power control unit 101e indicates that the maximum total power consumption in the period P3 is likely to exceed the threshold (that is, the power grid 99). Is displayed on the display unit 103 or the like (step S207) to notify or warn the user of this. Note that the power control unit 101e may notify this by using a not-illustrated notifying unit other than the display unit 103 or an audio output unit including a speaker, for example. As a result, the user can be alerted and power consumption can be suppressed. Note that the processing in step S205 and step S206 may be omitted. In this case, unintended suppression of power consumption of the electric device 20 is prevented.

  After the process of step S207, the power control unit 101e returns to step S201 and repeats the above process. Thereafter, if the control specified by the control content still remains, the remaining control is performed again.

  Note that the power control unit 101e also determines whether or not the current time is a time that does not correspond to the suppression timing for the thing controlled in the past at an appropriate timing (that is, the time is currently being performed). It is determined whether or not the execution end time in the power consumption suppression control is exceeded. If it is determined that it is not applicable (that is, the time has exceeded the execution end time), an instruction to cancel the suppression of power is supplied to the electrical device 20 that is the control target. This release instruction is also supplied to the electrical device 20 via the first communication unit 104 and the device control network N1. For example, if the control content is “before 6:30; IH cooking heater, after 6:30; air conditioner” in the data table 3 of FIG. 8, and the current time is after 6:30, Since the time does not coincide with the suppression timing before 6:30, the power control unit 101e specifies the IH cooking heater 22 which is the electric device 20 corresponding to the timing, and supplies the release instruction to the IH cooking heater 22.

  When the control unit 201 of the electrical device 20 receives the release instruction via the communication unit 204, the control unit 201 controls the various elements 203 so as to be in a state before being controlled by the control method. For example, when the control method is to increase the set temperature by 1 ° C., the control unit 201 decreases the set temperature by 1 ° C. By doing so, when the data table 3 of FIG. 8 is “before 6:30; IH cooking heater, after 6:30; air conditioner”, the power consumption peak of both can be shifted. The maximum value of total power consumption can be suppressed.

  After step S107 of FIG. 9, the power control unit 101e waits until the period P3 has elapsed (step S108). Then, when the period P3 elapses, the end of the period P3 is notified to each electric device 20 (step S109). And it returns to step S101 and the said process is repeated by the specific part 101a. The notification is performed via the first communication unit 104 and the device control network N1. When the control unit 201 of the electrical device 20 receives the notification via the communication unit 204, the control unit 201 controls the various elements 203 so as to be in a state before being controlled by the control method. For example, when the control method is to increase the set temperature by 1 ° C., the control unit 201 decreases the set temperature by 1 ° C. As a result, the suppression of the total power consumption in the period P3 is released.

  In the present embodiment, as described above, since the life pattern of the normal user is determined, the user often uses the same electrical device 20 in the same usage method during the same type of period. . For this reason, the increase in the total power consumption is likely to be the same in the same type of period. In the present embodiment, paying attention to such points, since the predicted value for the total power consumption is set according to the period, the current value of the total power consumption and the prediction of the amount of change in the total power consumption in the period P3. The maximum power consumption (predicted power) in the period P3 based on the value can be accurately predicted. Then, when the total power consumption (that is, the current value) before the period P3 arrives is high, when the predicted value of the maximum power consumption exceeds the threshold value, the electric device 20 is controlled so as to suppress the total power consumption. Therefore, power consumption can be suppressed before the total power consumption of the plurality of electrical devices 20 increases. In particular, it is possible to accurately prevent inconveniences such as the breaker of the power distribution device 60 being dropped and the total power consumption being too large. In addition, an energy saving effect can be expected by preventing the total power consumption from becoming too large.

  Further, in the present embodiment, the power control unit 101e performs a suppression instruction (suppression value) that is an instruction to suppress power consumption according to the control content set in advance according to the period specified by the specifying unit 101a. ) Is transmitted for each of the plurality of electrical devices 20 or each of the plurality of electrical devices 20. And the electric equipment 20 will specify the suppression aspect (suppressed power) of the power consumption based on an instruction | indication based on an own operation condition, and will transmit the specified said suppression aspect to the said power control apparatus, if the suppression instruction | indication is received. Then, the power control unit 101e performs processing (new suppression instruction and / or notification) according to the suppression mode received by the reception unit 101f (for example, according to the comparison result between the suppression mode and the suppression instruction).

  Thereby, for example, even when the power consumption is not successfully suppressed, appropriate processing is performed. Since the electric device 20 does not necessarily need to suppress power consumption, the electric device 20 may not suppress power consumption depending on the operation mode. For this reason, when the user is using the electric device 20, the inconvenience due to power consumption being suppressed (for example, the set temperature of the air conditioner 24 is increased or decreased. The cooking temperature of the IH cooking heater 22 is reduced. Etc.) is suppressed. That is, with the above configuration, it is possible to attempt energy saving while suppressing inconvenience that may occur due to power saving. In particular, in the above, when the electric device 20 cannot suppress power consumption, it can supply the power control device 10 with information to that effect (in the above, information that the suppression power is 0). The inconvenience is suppressed. In addition, when a new suppression instruction (suppression value) is transmitted, even if the initial suppression of the total power consumption fails, the total power consumption can be suppressed by the other electrical device 20, so the total power consumption is appropriately controlled. I can do it.

  In addition, as described above, if the predicted value is based on the past total power consumption, the predicted value matches the user's behavior pattern, etc., so the predicted power can be accurately predicted, Total power consumption can be controlled appropriately.

  Further, in the present embodiment, by the processing as described above, the power control unit 101e causes the one or more electric devices 20 of the plurality of electric devices 20 to be set according to the control content set in advance according to the period specified by the specifying unit 101a. The total power consumption is controlled by controlling the power consumption of the device. As a result, the control content can be adapted to the user's behavior according to the above period (see the description of the data table 3), and as described above, energy saving is attempted while suppressing inconvenience that may be caused by power saving. It will be possible.

  The storage unit 102 stores a data table 5. As shown in FIG. 14, the data table 5 is a table in which the weather and the predicted value of the power generation amount are recorded in association with each other for each period. Note that the predicted value of the power generation amount is the same as power consumption and is an instantaneous value in the present embodiment, but may be an accumulated value in the same period as the power consumption. The predicted value of the power generation amount is the power generation amount predicted for the period and the weather.

  Note that the predicted value of the power generation amount may be recorded by the recording unit 101k. For example, the recording unit 101k supplies information representing the amount of power generated by the power generation apparatus 97 from the power conditioner 50 in real time, and supplies current climate information from the Internet or the like via the HGW 30 in real time. The recording unit 101k acquires information indicating the amount of power generation from the power conditioner 50 via the home communication network N2 and the second communication unit 105, and acquires climate information from the HGW 30. At the same time, the recording unit 101k acquires date and time information supplied from the calendar unit 106. Based on the acquired information, the recording unit 101k takes, for example, an average value of the power generation amount for each time period in the period and for each climate specified by the climate information, and uses the average value as a predicted value. A data table 5 may be created. Further, thereafter, the recording unit 101k may appropriately update the predicted value of the power generation amount by performing a weighted average or the like on the power generation amount.

  The prediction unit 101g refers to the calendar unit 106, and acquires the current climate information from the external network N3 via the HGW 30 when the period specified by the specification unit 101a arrives. This climate information is acquired via the in-home communication network N2 and the second communication unit 105.

  And the prediction part 101g acquires the predicted value of the electric power generation amount | corresponding to these from the memory | storage part 102 by using the said climate information and the said period as a key. When the prediction unit 101g acquires the predicted value of the power generation amount, the power control unit 101e increases the threshold based on the predicted value of the power generation amount, for example, before performing the process of step S105 in FIG. The total power consumption is further controlled by reducing the suppression value (for example, by subtracting the prediction value of the power generation amount from the suppression value). When the electric power generated by the power generation device 97 can be used in each electric device 20 or the like, the power consumption from the electric power system 99 can be suppressed. Therefore, in such a case, it is not necessary to cause the electric device 20 to suppress power consumption unnecessarily. And since the suppression amount of power consumption is reduced by the said control, it will not make the electric equipment 20 suppress power consumption unnecessarily.

  The power control unit 101e supplies power from the power conditioner 50, controls the power distribution device 60, and preferentially supplies power from the power conditioner 50 to each electrical device 20. Thereby, power consumption from the power system 99 is suppressed. For example, the power control unit 101e satisfies the predetermined condition such that the predicted value is larger than a predetermined reference and the user operates the operation unit 107 and an operation signal corresponding to the operation is supplied. In addition, the control processing of the total power consumption may be stopped, and power from the power conditioner 50 may be preferentially supplied to each electric device 20.

  Further, for example, the amount of power consumption may be specified by transmitting information indicating the amount of power consumption via the external network N3 from the outside such as an electric power company that supplies power from the power system 99. This information is supplied to the power control apparatus 10 via the HGW 30 and the home communication network N2. The receiving unit 101f of the power control apparatus 10 receives the information via the second communication unit 105 (that is, receives the designation). The threshold changing unit 101m changes the threshold according to the designated power consumption received by the receiving unit 101f. Here, this power consumption is replaced with a threshold value. As a result, the amount of suppression of the total power consumption can be changed in response to an external request from an electric power company or the like.

  In addition, this invention is not limited to the said embodiment, Of course, the various change in the range which does not deviate from the summary of this invention is possible.

  For example, the period may be divided according to the climate. For example, the daytime of a hot summer holiday (for example, 27 ° C. or higher) and the daytime of a cool summer holiday (for example, less than 27 ° C.) may be set depending on the temperature even during the daytime of the same summer holiday. Since the user may behave differently on a hot day and a cool day, the control contents of the data table 3 may be made different. In this way, the total power consumption can be controlled more accurately depending on the climate.

  The period may be a period when the user goes out. In this case, the specifying unit 101a uses a human sensor (not shown) or the like (for example, provided in the electronic control device 10) to detect the presence of a human being for a certain period or longer, and the period to come is Is identified as the period when the person went out. As a result, it is possible to prepare the contents of control for going out of the user, and to accurately control the total power consumption.

  Further, the total power consumption may be handled as a total value of power consumption for each outlet or electrical device 20. In this case, when calculating the predicted power based on the predicted value and the current value, the predicted power may be calculated by calculating the power consumption for each outlet or electrical device. Further, in this case, the control unit 101 acquires power consumption for each outlet and each electrical device 20 by communicating with each electrical device 20 or the power sensor 40.

  Further, the total power consumption may be the total power consumption of only the plurality of electrical devices 20. In this case, the power sensor 40 can measure the total power consumption.

  The total power consumption may be the total power consumption for each room. In this case, a part of the function of the power control apparatus 10 (for example, the first communication unit 104) may be installed in each room as a slave unit. However, even in this case, as a whole, including the slave unit, The power control device 10 is obtained.

  The plurality of types of periods may be periods that are classified by information including any of time zone, date, climate, and whether or not the user has gone out. Basically, in the period divided by these pieces of information, the user is highly likely to perform the same action, so the control content can be set accurately. In particular, this can be said when the period is divided by information including a time zone and a date.

<Embodiment 2>
Next, a power control system according to Embodiment 2 of the present invention will be described. The power control system according to the second embodiment has the same configuration and function as the power control system 1 according to the first embodiment. For this reason, the code | symbol used for description of the electric power control system which concerns on Embodiment 2, each apparatus which comprises this system, and the structure and function of each apparatus uses the code | symbol same or similar to the code | symbol used in Embodiment 1. FIG. Moreover, the description which overlaps with Embodiment 1 is abbreviate | omitted suitably.

  A residence provided with the power control system 1 according to the second embodiment includes a power generation device 97 that is a solar cell and a plurality of electrical devices 20, as in the first embodiment. The generated power generated by the power control system 1 according to the second embodiment draws a curve having a maximum value at noon as shown in FIG. 15, and the total power consumed by the plurality of electrical devices 20 is shown in FIG. Curves having peaks are drawn in the morning time zone and the evening time zone as shown. This is because the resident of the residence according to the second embodiment (that is, the user of the power control system 1) lives in a life pattern in which the house is absent during the daytime.

Here, the residence provided with the power control system 1 according to the second embodiment includes, for example, the amount of power generated by the power generation device 97 in a predetermined period such as one day and the total power consumption consumed by the power control system 1. Is less than a residence that does not include the power control system 1. For this reason, in order to generate the electric power consumed in the residence provided with the power control system 1, for example, the amount of carbon dioxide discharged from an electric power company or the like by burning fossil fuel includes the power control system 1. Less than no dwelling. Therefore, the residence provided with the power control system 1 according to the present invention is referred to as a low CO ₂ house. In particular, a residence where the difference between the power generation amount of the power control system 1 and the total power consumption of the power control system 1 is a value “0” (that is, the power generation amount and the total power consumption are equal) in a predetermined period is: It is called zero-emission housing.

The power control system 1 according to the present embodiment uses a storage battery 98a of an EV (Electric Vehicle: electric vehicle) 98 as a storage unit that stores the power generated by the power generation device 97, and the stored power is supplied to the electric device 20. Used as a power source to supply. For this reason, in order to realize a low-CO ₂ house, when the power generated by the power generation device 97 is not consumed, it is necessary to store power as long as the storage battery 98a can store power.

  Here, the storage battery 98a of the EV 98 is composed of, for example, a lithium secondary battery. For this reason, for example, when a voltage higher than a predetermined voltage is applied to the storage battery 98a by overcharging, the electrolytic solution accumulated in the storage battery 98a is decomposed. For this reason, the amount of power that can be stored in the storage battery 98a decreases (that is, deteriorates). Further, the storage battery 98a deteriorates even when the state in which the internal voltage of the storage battery 98a is higher than the predetermined voltage is maintained for a predetermined time or more due to, for example, the charge amount being larger than a predetermined value. In particular, if the storage battery 98a is left in a fully charged state for a long time, it will deteriorate severely.

  When the storage battery 98a deteriorates, the resale value (that is, the resale price) of the storage battery 98a is lower than the storage battery 98a that has not deteriorated. Further, the distance that EV 98 can travel without charging (that is, the cruising distance that can travel only with the electric power stored in storage battery 98a) is shorter than before the deterioration. Furthermore, since the EV 98 preferentially uses the electric power stored in the storage battery 98a for the traveling of the EV 98 over the air condition, the convenience for the user is lowered.

  Therefore, hereinafter, the power control system 1 that can suppress a decrease in convenience of the vehicle that accumulates the generated power while reducing the difference between the generated power amount and the total power consumption in the predetermined period will be described.

  The power conditioner 50 of FIG. 1 includes, for example, a charging cable connected to the storage battery 98a of the EV 98, a voltage measuring unit that measures a voltage difference between a positive electrode terminal and a negative electrode terminal of the charging / discharging cable at regular intervals, and a voltage measuring unit. Based on the measured voltage difference, a connection detection unit that detects whether the EV 98 and the charge / discharge cable are connected at a fixed period and information indicating the connection state between the EV 98 and the charge / discharge cable are determined to the power control device 10. And a transmission unit for transmitting at a cycle. The connection detection unit transmits, for example, a signal for obtaining a response at a fixed period to an ECU (Engine Control Unit) included in the EV 98, and when the response signal is not transmitted from the EV 98 for a predetermined time or more, It may be detected that the connection with the power conditioner 50 is released.

  In addition, the power conditioner 50 further includes a detection unit that detects the amount of power stored in the storage battery 98a of the EV 98 at regular intervals, and the storage amount detected by the detection unit is the maximum amount of power that can be stored in the storage battery 98a. The storage rate information represented by the ratio (hereinafter referred to as the storage rate) with respect to the value (hereinafter referred to as the maximum stored power amount) is transmitted to the power control apparatus 10 at regular intervals. The power conditioner 50 is also connected to a power line used for selling the power generated by the power generator 97 to the power company in addition to the power line described with reference to FIG.

  Furthermore, the power conditioner 50 further includes a generated power measuring unit that measures the power generated by the power generation device 97 at a predetermined cycle, and transmits information representing the measured power to the power control device 10 at a predetermined cycle.

  Here, since the power generation device 97 generates power using sunlight as an energy source, the power generated by the power generation device 97 is characterized by, for example, a scene characterized by a time period, a season, and a period divided by the weather (hereinafter referred to as “power generation device 97”). Can be categorized into multiple types of power generation patterns.

  For example, in a power generation scene in the morning time zone (from 6:00 am to 10:59 am), the time transition of the generated power draws a rising curve as shown in FIG. On the other hand, in the noon time zone (11:00 am to 14:59 am), the time transition of the generated power draws a curve having a peak at noon. Furthermore, in the evening time zone (from 15:00 am to 17:59), the time transition of the generated power draws a descending curve. Furthermore, in the evening (evening) time zone (from 18:00 am to 22:59) and late-night / early morning hours (from 23:00 am to 5:59 am), the generated power is “0”. It becomes.

  In addition, if the power generation scene is characterized by the same time zone, the power generation amount that is characterized by the “summer” season is greater than the power generation amount that is characterized by the “winter” season. . Furthermore, if the power generation scene is characterized by the same time zone and season, the power generation amount in the power generation scene on the “sunny day” is larger than the power generation amount in the power generation scene on the “rainy day”.

  For this reason, the memory | storage part 102 of FIG. 2 memorize | stores a power generation scene table as shown to FIG. 16 (A). The power generation scene table in FIG. 16A includes information representing a power generation scene, information representing a period (season, time zone, and weather) that characterizes the power generation scene, and a time to be determined in a period characterizing the power generation scene, Information representing a condition including a period and information for identifying a power generation pattern of the power generation device 97 in a power generation scene (hereinafter referred to as a power generation pattern ID) are stored in association with each other.

  Further, the storage unit 102 stores information representing the power generation pattern identified by the power generation pattern ID for each power generation pattern ID stored in the power generation scene table of FIG. 16A, as shown in FIG. 16B. A simple power generation pattern table. The power generation pattern table in FIG. 16B stores a plurality of information indicating the time when power generation is performed with the power generation pattern and information indicating the generated power at the time.

  By the way, the daily life that a user usually operates can be categorized into a plurality of types of life patterns for each scene (hereinafter referred to as a life scene) characterized by, for example, a day of the week and weather as well as a time zone and a season. . For this reason, when the user's life pattern is different, the usage pattern of the EV 98 and the usage pattern of the electric device 20 used by the user are different. When the usage pattern is different, the pattern of the stored power amount of the storage battery 98a consumed by using the EV 98 and the pattern of the power consumption consumed by the electric device 20 are different.

  For example, many users usually sleep at midnight / early morning hours, get up in the morning hours, use the electric device 20, and then work by bus or train. Also, many users wake up later in the winter season than in the summer season. Furthermore, since many users go to work on weekdays, the EV 98 is not used, and the use opportunities of the electric device 20 are also reduced. On the other hand, since many users do not work on holidays, the use opportunity of the electric equipment 20 increases and the use opportunity of EV98 also increases. In addition, many users set the set temperature of the air conditioner 24 higher on a rainy winter day or use the EV 98 more frequently than on a sunny day in winter.

  For this reason, the memory | storage part 102 of FIG. 2 memorize | stores a life scene table as shown in FIG. This life scene table includes information representing a life scene, information representing a period characterizing the life scene (separated by season, time zone, day of the week, and weather), and a period to be determined as a period characterizing the life scene. Alternatively, information indicating a condition including time and information for identifying a user's life pattern in a life scene (hereinafter referred to as a life pattern ID) are stored in association with each other.

  The life scene may be characterized by user behavior. For example, the life scene may be a life scene “absence” characterized by the absence of a user and a life scene “danran” characterized by a plurality of users gathering in a living room or the like. This life scene “absence” is specified by the specifying unit 101a when, for example, information indicating that a predetermined number or more of electric devices such as lighting are not lit in the “evening” period is received by the receiving unit 101f. The In addition, in the life scene “Danran”, for example, information indicating that the lighting of the living room is lit in the “evening” period is received by the receiving unit 101f, and information indicating that the lighting of the child room is not lit. When the information indicating that the bedroom lighting is not lit, the information indicating that the bathroom lighting is not lit, or the like is received, it is specified by the specifying unit 101a. The life scenes “absence” and “danran” are characterized in that they continue for a predetermined time or longer after the start of these scenes. For example, in the life scene “Danran”, since a plurality of users enjoy conversations, the usage status of the electric device 20 may not change over a predetermined time after the life scene is identified as “Danran”. is expected. Similarly, for example, since the user does not use the power control system 1 until the user goes home after going out to the destination after the user goes out to the destination, for example, the life scene “absent” is specified as “absence”. It is predicted that the usage status of the electric device 20 will not change over a predetermined time.

  The storage unit 102 in FIG. 2 stores an EV usage pattern table as shown in FIG. This EV use pattern table includes a life pattern ID for identifying a life pattern, information indicating the time when the use of the EV 98 is started and information indicating the time when the use is ended in the life classified as the life pattern, The amount of power consumed by use is stored in association with power consumption rate information that is expressed as a percentage of the maximum stored power amount of the storage battery 98a included in the EV 98.

  Further, the storage unit 102 in FIG. 2 stores an EV use schedule table as shown in FIG. 19 in which information indicating the use schedule (use start date and use end date) of the EV 98 is stored. The information stored in the EV use schedule table is information input by the user from the operation unit 107 in FIG. 2 according to the operation, and is information stored by the recording unit 101k.

  The storage unit 102 stores, for each life pattern ID stored in the life scene table of FIG. 17, information indicating the usage pattern of the electric device 20 used in the life pattern identified by the life pattern ID. The electric equipment utilization pattern table as shown in FIG. The usage pattern table in FIG. 20 associates information representing the usage time of the electrical device 20, information representing the power consumption of each electrical device 20, and information representing the sum of each power consumption (that is, total power consumption). I remember.

  Here, even if a certain type of electric device 20 operates in the same operation mode, an initial stage from the start of operation until a predetermined time elapses, and a later stage after a predetermined time elapses from the start of operation And power consumption is different. For example, in an initial stage from when the air conditioner 24 starts operation until a predetermined time elapses, power consumption required to warm a cold room increases with time. Thereafter, when the predetermined time elapses and the latter stage is reached, the room is warmed to the vicinity of the set temperature, so that the power consumption consumed by the air conditioner 24 continues to decrease after reaching a peak and eventually converges to a substantially constant value. The same applies to the IH cooking heater 22, and there is a peak in the transition of electric power consumed by the IH cooking heater 22 when heating a pan or the like. For this reason, the power control device 10 according to the present embodiment reduces the instantaneous total power consumption (total power consumed by each electrical device 20), and the usage time of the electrical device 20 such as the air conditioner 24. By shifting the band, the time period in which the power consumed by each electric appliance reaches its peak is dispersed (so-called peak shift), and the peak of the total power consumption is reduced.

  Here, the deterioration of the convenience experienced by the user by shifting the use time zone of the electric device 20 varies depending on the type of the electric device 20 and the life scene. For example, in the life scene during the “winter weekday morning” period, the operation time of the air conditioner 24 is less likely to decrease due to the operation time of the air conditioner 24 being earlier than that at the time of waking up. However, since the user goes out from the futon warmed by the body temperature to the cold room, the convenience is likely to be lowered.

  In addition, certain types of electrical equipment 20 have different power consumption for each operation mode. For example, the air conditioner 24 and the IH cooking heater 22 have an operation mode (power saving mode or the like) that consumes less power than the normal operation mode. For this reason, the power control apparatus 10 according to the present embodiment changes the operation mode of the electric device 20 such as the air conditioner 24 in order to reduce the instantaneous total power consumption.

  Here, the decrease in convenience experienced by the user by changing the operation mode of the electric device 20 varies depending on the type of the electric device 20 and the life scene. For example, in the life scene “spring weekday morning”, the air-conditioner 24 operation mode becomes the power saving mode, so that the convenience of the user is hardly lowered, but if the operation mode of the IH cooking heater 22 changes, the cooking of the breakfast fails. And the convenience for the user is reduced due to the increased cooking time.

  Therefore, the storage unit 102 in FIG. 2 stores a control pattern table as shown in FIG. This control pattern table includes a life scene ID for identifying a life scene, information representing an operation device assumed to be used in a life classified as a life scene, and peak shift control performed to reduce the total power consumption. Alternatively, information indicating the contents of the operation mode control is stored in association with each other. Here, the information indicating the content of the peak shift control or the operation mode control is the control target and the information indicating the priority order for executing the peak shift control or the operation mode control among the operation devices expected to be used. Information indicating a device to be controlled, and information indicating a control method such as how to shift the peak and what operation mode to change.

  Note that the power control system 1 according to the present embodiment includes a plurality of sensors that measure the power consumption consumed by the electrical device 20 in a predetermined cycle for each electrical device 20. Each sensor transmits information representing the power consumption measured by each sensor to the power control apparatus 10 via the device control network N1 in FIG. 1, and the recording unit 101k of the power control apparatus 10 illustrated in FIG. Each of the information indicating the received power consumption, the information indicating each reception time, and the information indicating the total power consumption, which is the sum of the respective power consumptions, are recorded in the storage unit 102 as a history.

  In addition, information indicating the storage amount by the storage rate received from the power conditioner 50 by the power control device 10 (that is, information indicating the storage rate of the storage battery 98a mounted on the EV 98) is received by the recording unit 101k. The information is recorded as a history in the storage unit 102 in association with the information to be expressed. Further, the recording unit 101k determines that the use of the EV 98 is started when the information indicating the storage rate is not received for a predetermined time or more, and uses the EV 98 use start time as the information indicating the current time provided from the calendar unit 106. It is recorded as history in the storage unit 102 as information to be expressed. Thereafter, when the information indicating the storage rate is received, the recording unit 101k determines that the use of the EV 98 has ended, and information indicating the current time provided from the calendar unit 106 is used as information indicating the use end time of the EV 98. Records as a history in the storage unit 102. Further, the recording unit 101k is consumed by using the EV 98 by subtracting the storage rate represented by the information received at the use end time from the storage rate represented by the information received at the use start time. The power consumption rate corresponding to the amount of power is calculated, and the information indicating the calculated power consumption rate, the information indicating the use start time, and the information indicating the use end time are associated and recorded as a history in the storage unit 102. .

  Note that at least one of the information indicating the use start time, the information indicating the use end time, and the information indicating the power consumption rate recorded by the recording unit 101k as a history is sent from the ECU included in the EV 98 to the power conditioner 50. It may be information received via.

  Further, information representing the generated power received from the power conditioner 50 by the power control apparatus 10 is recorded as a history in the storage unit 102 in association with information representing the reception time by the recording unit 101k.

  The contents of each table shown in FIGS. 16 to 21 are updated (that is, learned) at a predetermined cycle based on information stored as a history in the storage unit 102. Specifically, the control unit 102 calculates, for each piece of information representing a time included in a period characterizing the same scene, an average value of the generated power represented by information associated with the information representing each time. Then, the generated power pattern as shown in FIG. Similarly, the control unit 102 learns the usage pattern of the EV 98 as shown in FIG. 18 and the usage pattern of the electric device 20 as shown in FIG. Note that the contents of each table shown in FIGS. 16 to 21 may be stored in advance in each table at the time of factory shipment or the like, and the operation unit 107 in FIG. 2 inputs according to the user's operation. The information may be information recorded by the recording unit 101k.

  In the present embodiment, the control unit 101 in FIG. 2 executes a power control process as shown in FIG. In order to simplify the description in the description of the power control process, the discharge of the storage battery 96 and the charging of the storage battery 96 in FIG. 1 are not considered.

  When the power control process of FIG. 22 is started, the control unit 101 determines whether the EV 98 is connected to the power conditioner 50 based on the information indicating the connection status received from the power conditioner 50 by the reception unit 101f of FIG. It is determined whether or not (step S401). At this time, if it is determined that the EV 98 is connected to the power conditioner 50 (step S401; YES), the control unit 101 executes an EV connection power control process as shown in FIG. 23 (step S402).

  When the EV connection power control process in FIG. 23 is started, the specifying unit 101a of the control unit 101 shown in FIG. 2 executes a current scene specifying process for specifying the current life scene and the power generation scene (step S411). Specifically, the specifying unit 101a specifies the current weather based on the latest climate information received from the HGW 30 in FIG. Further, the specifying unit 101a specifies the period condition of the power generation scene table shown in FIG. 16A that satisfies the specified weather and the current time represented by the information supplied from the calendar unit 106. Thereafter, the specifying unit 101a specifies the power generation scene represented by the information associated with the information indicating the specified period condition as the current power generation scene. Similarly, the specifying unit 101a specifies a life scene from the life scene table of FIG. 17 based on the current time zone, season, day of the week, and period represented by the weather. In the present embodiment, the specifying unit 101a has been described as specifying the current life scene and the power generation scene. However, the present invention is not limited to this, and as in the first embodiment, ( That is, you may specify the life scene and power generation scene which will come from now on.

  After step S411 in FIG. 23, the prediction unit 101g executes EV usage status prediction processing for predicting the usage status of the EV 98 in the identified scene (step S412). Specifically, the prediction unit 101g predicts the usage time zone of the EV 98 and the stored power consumed by the use of the EV 98. For this purpose, the prediction unit 101g searches the life pattern table of FIG. 17 for a life pattern ID that identifies the user's life pattern in the current life scene specified in step S411. Thereafter, the prediction unit 101g corresponds to the time zone in which the user uses the EV 98 and the amount of stored power consumed by the EV 98 in the life pattern identified by the searched life pattern ID from the EV use pattern table of FIG. The power consumption rate is acquired (that is, the prediction unit 101g searches for information representing the use start time and information associated with the life pattern ID, information representing the use end time, and information representing the power consumption rate).

  Further, the prediction unit 101g searches the EV usage schedule table of FIG. 19 for information indicating the scheduled usage period (information indicating the usage start date and information indicating the usage end date) in the period from the current date to a predetermined time later. Thereafter, the prediction unit 101g predicts a period including the current time, which is a period in which the EV 98 is not scheduled to be used (hereinafter referred to as a non-use period), based on the retrieved information indicating the scheduled use period. In the present embodiment, the prediction unit 101g has been described as specifying the non-use period of the EV 98 based on the use schedule stored in the use schedule table in FIG. 19, but the present invention is not limited to this. For example, the prediction unit 101g may specify the EV98 non-use period based on information indicating the EV98 usage status stored in the usage pattern table of FIG.

  After step S412 in FIG. 23, the threshold value changing unit 101m executes a storage rate setting process for determining a suitable storage rate of the storage battery 98a included in the EV 98 based on the usage status of the EV 98 searched in step S412 (step S413). . In the storage rate setting process, for example, based on data stored in a setting file stored in advance in the storage unit 102, a suitable storage rate for a long-term non-use, a minimum storage rate for scheduled use, a preferable storage rate for steady state, A value of a preferable power storage rate at the time of power surplus and a preferable power storage rate at the time of power shortage is set.

  Here, the preferable storage rate when not in use for a long period of time is a preferable storage rate that can prevent deterioration of the storage battery 98a when the storage battery 98a of the EV 98 is not discharged for a long time because the EV 98 is not used for a long time. Say. In the present embodiment, description will be made assuming that the preferred storage rate when not in use for a long time is 20%. Here, the preferable storage rate when not in use for a long period of time is that the storage battery 98a of the EV 98 does not deteriorate due to overcharge even when the discharge is not performed over a long period of time (that is, exceeding the predetermined period) or in the predetermined period Even if the internal voltage of the storage battery 98a is so low that the deterioration of the storage battery 98a is lower than a predetermined level (that is, the storage rate is low) and charging is not performed over the long period of time, Since the storage battery 98a is an example of a power storage rate that is high enough that the storage battery 98a does not deteriorate due to overdischarge or the degree of deterioration of the storage battery 98a in a predetermined period is lower than a predetermined level, It is not limited to 20%. For this reason, those skilled in the art can determine a more preferable long-term non-use suitable storage rate by experiment. In addition, in this embodiment, overdischarge means that the electrical storage rate of the storage battery 98a becomes lower than a suitable electrical storage rate at the time of long-term non-use. In addition, the degree of deterioration of the storage battery 98a in the predetermined period is represented by, for example, a value obtained by subtracting the maximum stored power amount of the storage battery 98a at the end of the predetermined period from the maximum stored power amount of the storage battery 98a at the start of the predetermined period. be able to.

  The minimum storage rate at the time of planned use does not prevent the planned use of the EV 98, and even if the EV 98 is actually used as planned, the degree of deterioration of the storage battery 98a during a predetermined period even if the storage battery 98a does not deteriorate due to overdischarge. Is the lowest power storage rate among the power storage rates expected to be higher as the value becomes lower than a predetermined level. In the present embodiment, the description will be made assuming that the scheduled storage minimum storage rate is a value obtained by adding the power consumption rate predicted in step S412 to the long-term non-use preferable storage rate.

  The constant suitable storage rate is that the insufficient power generated in the power control system 1 is smaller than a predetermined threshold (hereinafter referred to as an insufficient power threshold) and the surplus power is smaller than a predetermined threshold (hereinafter referred to as an excess power threshold). It is a suitable storage rate at a constant time (that is, when there is no excess or shortage of power or when it is less than a predetermined value), and indicates a storage rate that can prevent deterioration of the storage battery 98a while ensuring the convenience of the EV 98. In the present embodiment, the description will be made assuming that the preferable storage rate at normal time is 70%. However, the preferred storage rate at the time of steady operation is high enough to prevent a decrease in convenience of EV98 even when EV98 is used in a mode different from the usage pattern (that is, it is lower than the lowest storage rate at the time of scheduled use). Is also an example of a storage rate that is low so that the storage battery 98a of the EV 98 due to overcharging does not deteriorate or the deterioration of the storage battery 98a during a predetermined period becomes lower than a predetermined level. The always preferred power storage rate is not limited to 70%. For this reason, those skilled in the art can determine a more preferable steady-state preferable storage rate by experiment. Moreover, those skilled in the art can determine more suitable underpower threshold and excess power threshold by experiment. In addition, in this embodiment, overcharging means that the electrical storage rate of the storage battery 98a becomes higher than a suitable electrical storage rate at the time of steady state.

  The preferable power storage rate at the time of power surplus is a power storage rate preferable at the time of power surplus when the surplus power generated in the power control system 1 is larger than the surplus power threshold (in this case, the power control system 1 is in a power surplus state). Thus, the storage rate is higher than the normal preferable storage rate, which can prevent deterioration of the storage battery 98a within a predetermined time (hereinafter referred to as the overcharge limit time). In the present embodiment, the description will be made assuming that the preferable power storage rate at the time of surplus power is 80%. However, the preferred storage rate at the time of surplus power is higher than the preferred storage rate at steady state and within the overcharge limit time, the storage battery 98a mounted on the EV 98 due to overcharge does not deteriorate or the storage battery 98a deteriorates during a predetermined period. Since this is an example of a power storage rate that is lower as the degree becomes lower than a predetermined level, the preferred power storage rate at the time of surplus power is not limited to 80%. For this reason, those skilled in the art can determine a more preferable power storage rate at the time of surplus power and an overcharge limit time by experiments.

  In the power control system 1, the preferred storage rate at the time of power shortage is a shortage of power that occurs within a predetermined time shorter than the overcharge limit time (hereinafter referred to as a preparation time for power shortage) greater than the power shortage threshold (insufficient) When it is predicted that the power becomes larger than the power shortage threshold is called power shortage and the power control system 1 is in a power shortage state), it is predicted that the power shortage can be eliminated or alleviated. It is a suitable power storage rate, and refers to a power storage rate that can prevent deterioration of the storage battery 98a and the like within the preparation time for power shortage. In the present embodiment, since the preparation time for power shortage is sufficiently short, it is assumed that the preferable power storage rate at the time of power shortage is 100%. However, the preferred storage rate at the time of power shortage is such that the storage battery 98a of the EV 98 due to overcharging does not deteriorate or the deterioration of the storage battery 98a during a predetermined period becomes lower than a predetermined level within the preparation time for power shortage. Is an example of a low power storage rate, the preferable power storage rate at the time of power shortage is not limited to 100%, but may be 99%. That is, a person skilled in the art can determine a more preferable power storage rate at the time of power shortage and a preparation time for power shortage by experiment.

  The storage battery 98a has a storage rate that is a preferable storage rate when not in use for a long time, a minimum storage rate when scheduled to be used, a preferable storage rate during steady state, a preferable storage rate during surplus power, and a preferable storage rate when power is insufficient. The amount of power stored in 98a is referred to as a first stored amount, a second stored amount, a third stored amount, a fourth stored amount, and a fifth stored amount, respectively.

  After step S413 in FIG. 23, the power control unit 101e determines whether or not the currently unused non-use period predicted in step S412 is a long period (a predetermined period or longer) (step S414). In the present embodiment, the long term is described as being, for example, a period of one month or more, but is not limited thereto, and those skilled in the art can determine a more suitable period by experiment.

  In step S414, when it is determined that the EV98 non-use period is long (step S414; YES), the power control unit 101e indicates that the storage rate represented by the information received from the power conditioner 50 is long-term. It is determined whether or not it is greater than the preferred storage rate when not in use (20% in the present embodiment) (step S415).

  If it is determined in step S415 that the storage rate of the storage battery 98a included in the EV 98 is 20% or less (step S415; NO), the above processing is repeated from step S411. When it is determined that the storage rate of the storage battery 98a included in the EV 98 is 20% or less (step S415; NO), the power control unit 101e determines that the difference between the storage rate of the storage battery 98a and 20% is less than a predetermined value. If it is determined whether or not the difference is larger than a predetermined value, the above-described processing may be repeated from step S411 after executing an overdischarge elimination processing described later with reference to FIG. On the other hand, when it is determined that the storage rate of the storage battery 98a included in the EV 98 is greater than 20% (step S415; YES), the power control unit 101e performs an overcharge elimination process as shown in FIG. After execution (step S416), the above processing is repeated from step S411.

  When the overcharge elimination process in FIG. 24 is started, the power control unit 101e transmits an instruction to the power conditioner 50 to discharge the storage battery 98a included in the EV 98 (step S501). Next, the prediction unit 101g executes a discharge power prediction process for predicting the transition of the discharge power discharged by the storage battery 98a in the life scene specified in step S411 of FIG. 23 based on the storage rate of the storage battery 98a included in the EV 98. (Step S502).

  Next, the calculation unit 101d calculates a predicted value of the total power consumption that changes in the life scene based on the identified life scene (that is, calculates the predicted power for the total power consumption for a plurality of times). A power consumption prediction process is executed (step S503). Specifically, the calculation unit 101d searches for the life pattern ID associated with the information representing the current life scene specified in step S411 of FIG. 23 from the life scene table of FIG. Information representing the transition pattern of the total power consumption is acquired from the electric equipment utilization pattern table of FIG. 20 corresponding to the pattern ID. Next, the calculation unit 101d is information stored as a history in the storage unit 102 of FIG. 2 and represents total power consumption in a period from the current time to a time before a predetermined time (hereinafter referred to as a period before the predetermined time). To determine the actual transition of the total power consumption during the period up to a predetermined time. Next, the calculation unit 101d corresponds to the period up to a predetermined time before the transition pattern of the total power consumption represented by the acquired information so as to substantially match the actual transition of the total power consumption identified from the history. The portion to be corrected is corrected, and the same correction as that for the portion is performed on the remaining portion of the transition pattern. For example, when the part corresponding to the period up to a predetermined time before the transition pattern is corrected by “2”, if the part after the correction substantially matches the actual transition of the total power consumption, the calculation unit 101d The remaining part of the transition pattern is also doubled. For example, there may be a case where a friend is visiting a single-family house. In addition, for example, if the part corresponding to the period up to a predetermined time before the transition pattern is corrected to shift “30 minutes” in the negative direction of the time axis, the part after the correction is approximately the same as the actual transition of the total power consumption In this case, the calculation unit 101d performs correction so that the remaining part of the transition pattern is also shifted by “30 minutes” in the negative direction of the time axis. For example, the user may wake up “30 minutes” early.

  After step S503, the prediction unit 101g executes a generated power prediction process for predicting the generated power of the power generation apparatus 97 based on the power generation scene specified in step S411 of FIG. 23 (step S504). Specifically, the prediction unit 101g searches the power generation scene table of FIG. 16A for a power generation pattern ID associated with information representing the current power generation scene, and a diagram corresponding to the searched power generation pattern ID. Information representing the transition pattern of the generated power is acquired from the power generation pattern table of FIG. 16 (B), and the transition pattern of the generated power is corrected as in step S502.

  Next, the prediction unit 101g outputs the discharge power predicted in step S502, the total power consumption predicted in step S503, the generated power predicted in step S504, and the power supplied from the power system 99 in FIG. When the EV98 storage battery 98a is discharged in a period after a predetermined time from the current time, by substituting the threshold value (hereinafter referred to as the threshold value of the electric power system 99) set for the following expression (1): A surplus power prediction process for predicting surplus power that is not consumed by the electrical device 20 is executed (step S505).

  Surplus power = discharge power + generated power + threshold of power system 99-total power consumption (1)

  Note that the threshold value of the power system 99 may be determined in advance according to the breaker of the power distribution device 60 shown in FIG. 1, or based on information according to a user operation input from the operation unit 107 in FIG. May be determined. In particular, when the threshold value of the power system 99 is the value “0”, the house including the power control system 1 is referred to as “zero emission house”.

  After step S505, the prediction unit 101g determines whether any of the predicted values of surplus power in a period after a predetermined time from the current time is a negative value (step S506). At this time, if it is determined that one of the predicted values of surplus power is a negative value (that is, insufficient power is generated in a period after a predetermined time from the current time) (step S506; YES), power control The unit 101e executes a power consumption suppression process that suppresses power consumption (step S507). Specifically, the power control unit 101e, from the control pattern table of FIG. 21, the control content (that is, the priority order, the control target, and the control content associated with the information representing the life scene specified in step S411 of FIG. 23). Information representing the control method) is acquired, and the power consumption of the electric device 20 is suppressed according to the acquired control content. Specifically, an instruction for instructing to advance the operation start time, an instruction for instructing to change the operation mode, or the like is transmitted in order from the control target with the highest priority.

  After step S507, the reception unit 101f receives information indicating whether or not the instruction has been received and information indicating suppression power from the electrical device 20 that has transmitted the instruction, and the power control unit 101e is based on the received information. It is determined whether or not generation of insufficient power is avoided. After that, the power control unit 101e uses the received information, information indicating that the occurrence of insufficient power is avoided, information indicating that the occurrence of insufficient power is not avoided, or the like as information indicating the result of suppressing power consumption. . After that, the power control unit 101e executes a suppression result notification process for displaying information indicating the suppression result on the display unit 103 in FIG. 2 (step S508), and then ends the overcharge elimination process.

  If it is determined in step S506 that all of the predicted values of surplus power are positive values (that is, power shortage is not predicted) (step S506; NO), the power control unit 101e sends surplus power to the power company. After controlling the power conditioner 50 to be sold, the overcharge elimination process is terminated.

  If it is determined in step S414 in FIG. 23 that the EV98 non-use period is not long (step S414; NO), the power control unit 101e stores the power represented by the information received from the power conditioner 50. It is determined whether or not the rate is higher than the normal preferred storage rate (70% in the present embodiment) (step S417). At this time, if it is determined that the storage rate is higher than 70% (step S417; YES), the power control unit 101e increments the value of the time counter that counts the time exceeding the normal preferable storage rate by the value “1”. (Step S418). The time counter is initialized to a value “0” in the initial state.

  After step S418, the power control unit 101e determines whether or not the storage rate of the storage battery 98a is higher than the preferable storage rate at the time of surplus power (80% in the present embodiment) (step S419). At this time, if it is determined that the power storage rate is higher than 80% (step S419; YES), the power control unit 101e determines whether or not the value of the time counter is equal to or greater than the preparation time for power shortage (step S420). . At this time, if the power control unit 101e determines that the value of the time counter is equal to or greater than the preparation time for power shortage (step S420; YES), the overcharge elimination process is performed in the same manner as in step S416 in order to prevent deterioration of the storage battery 98a. Is executed (step S422), the process returns to step S411 and the above process is repeated.

  When it is determined in step S418 that the power storage rate is 80% or less (step S419; NO), the power control unit 101e determines whether the time counter value is equal to or longer than the overcharge limit time. Is determined (step S421). At this time, if the power control unit 101e determines that the value of the time counter is equal to or longer than the overcharge limit time (step S421; YES), after executing the overcharge elimination process (step S422), the process returns to step S411 and the above process repeat.

  If it is determined in step S417 that the power storage rate is 70% or less (step S417; NO), the power control unit 101e initializes the value of the time counter to “0” (step S423). Thereafter, the power control unit 101e determines whether or not the storage rate is lower than the preferred storage rate for long-term non-use (20% in the present embodiment) (step S424). At this time, if it is determined that the storage rate is lower than the preferable storage rate when not in use for a long time (step S424; YES), the power control unit 101e executes the overdischarge elimination process as shown in FIG. 25 (step S425). ), The process returns to step S411 and the above process is repeated.

  When the overdischarge elimination process of FIG. 25 is started, the power control unit 101e transmits an instruction to charge the storage battery 98a included in the EV 98 to the power conditioner 50 (step S601). Next, the prediction unit 101g executes a charging power prediction process for predicting a transition of power charged in the storage battery 98a in the life scene specified in step S411 of FIG. 23 based on the storage rate of the storage battery 98a included in the EV 98. (Step S602). Thereafter, the calculation unit 101d and the prediction unit 101g perform the same processes as those in steps S503 and S504 in FIG. 24 (steps S603 and S604).

  Next, the prediction unit 101g calculates the charging power predicted in step S602, the total power consumption predicted in step S603, the generated power predicted in step S604, and the threshold value of the power system 99 using the following formulas: By substituting in (2), a surplus power prediction process is performed to predict surplus power that is not consumed by the electric device 20 when the storage battery 98a of the EV 98 is charged in a period after a predetermined time from the current time ( Step S605).

  Surplus power = Generated power + Threshold of power system 99-Charging power-Total power consumption (2)

  After that, the power control unit 101e completes the overdischarge elimination processing after executing the same processing as in Step S506 to Step S508 in FIG. 24 (Step S606 to Step S608).

  When it is determined in step S420 in FIG. 20 that the value of the time counter is smaller than the preparation time for power shortage (step S420; NO), it is determined in step S421 that the value of the time counter is smaller than the overcharge limit time. In the case (step S421; NO), or when it is determined in step S424 that the storage rate is equal to or higher than the preferred storage rate when not in use for a long time (step S424; NO), the power control unit 101e is as shown in FIG. After executing the normal storage process (step S426), the process returns to step S411 and the above process is repeated.

  When the normal power storage time process of FIG. 26 is started, the calculation unit 101d and the prediction unit 101g execute the same processes as steps S503 and S504 of FIG. 24, respectively (steps S701 and S702). Next, the predicting unit 101g substitutes the total power consumption predicted in step S701, the generated power predicted in step S702, and the threshold value of the power system 99 into the following equation (3), so that In the period from the time until the preparation time for power shortage (hereinafter referred to as power shortage preparatory period), when there is neither charging nor discharging of the storage battery 98a included in the EV 98, surplus power that is not consumed by the electric device 20 is generated. A surplus power prediction process to be predicted is executed (step S703).

  Surplus power = Generated power + Threshold of power system 99-Total power consumption (3)

  Next, the prediction unit 101g determines whether the surplus power is a positive value at the current time (step S704). At this time, if it is determined that the surplus power is a positive value (step S704; YES), the power control unit 101e instructs the power conditioner 50 to command the discharge to end if the storage battery 98a is discharging. Send to. Next, the prediction unit 101g determines whether or not a peak of insufficient power comes during the power shortage preparation period (step S705). Specifically, the prediction unit 101g sets the value obtained by reversing the sign of the surplus power in the power shortage preparation period as the power shortage in the power shortage preparation period, and if the power shortage is a positive value, the prediction unit 101g Determine that a shortage occurs. In addition, the prediction unit 101g determines that a peak of insufficient power is reached when the insufficient power exceeds the insufficient power threshold during the power shortage preparation period (that is, the power control system 1 falls into a power insufficient state).

  In step S705, when it is determined that the peak of insufficient power comes during the power shortage preparation period (step S705; YES), the power control unit 101e sets the upper limit of the power storage rate of the storage battery 98a included in the EV 98 as the preferable power storage rate at the time of power shortage. (100% in this embodiment) (step S706). On the other hand, when it is determined that the peak of insufficient power does not arrive during the power shortage preparation period (step S705; NO), the prediction unit 101g is in a state where the power generated by the power generation device 97 is currently excessive (that is, It is determined whether the power surplus state is present (step S707). Specifically, using the following formula (4), the prediction unit 101g calculates the surplus PV surplus power that is not consumed in the electrical device 20 among the power generated by the power generation device 97 at the current time, When determining that the calculated PV surplus power exceeds the surplus power threshold, it is determined that the power control system 1 is in the power surplus state.

  PV surplus power = Generated power-Total power consumption (4)

  In step S707, when it is determined that the power control system 1 is in the power surplus state (step S707; YES), the power control unit 101e sets the upper limit of the power storage rate of the storage battery 98a as the power surplus suitable power storage rate (this embodiment). 80%) (step S708). On the other hand, when it is determined that the power control system 1 is not in the power surplus state (step S707; NO), the power control unit 101e sets the upper limit of the storage rate of the storage battery 98a to the preferred storage rate at the normal time (in this embodiment, 70%) (step S709).

  After step S706, step S708, or step S709, the power control unit 101e determines that the storage rate of the EV 98 represented by the information received from the power conditioner 50 is set in step S706, step S708, or step S709. It is determined whether it is lower than the upper limit (step S710). At this time, if it is determined that the storage rate of EV 98 is lower than the upper limit of the storage rate (step S710; YES), power control unit 101e issues an instruction to charge PV surplus power to storage battery 98a included in EV 98. After the transmission to the power conditioner 50 (step S711), the execution of the normal accumulation control process is terminated. On the other hand, when it is determined that the storage rate is equal to or higher than the upper limit of the storage rate (step S710; NO), the power control unit 101e issues a command to end charging if the storage battery 98a is being charged. After transmitting to the power conditioner 50 (step S712), if necessary, an instruction to sell the PV surplus power to the power company is transmitted to the power conditioner 50, and then the normal accumulation control process is finished. To do.

  If it is determined in step S704 that the surplus power is equal to or less than the value “0” (that is, there is a possibility that power shortage may occur) (step S704; NO), the power control unit 101e determines that the storage battery 98a is being charged. If so, a command to finish charging is transmitted to the power conditioner 50. Next, the power control unit 101e sets the lower limit of the storage rate of the storage battery 98a provided in the EV 98 to the lowest planned storage rate (in this embodiment, 20% + the power consumption rate acquired in step S412 in FIG. 23). (Step S721). After that, the power control unit 101e determines whether or not the storage rate of the storage battery 98a included in the EV 98 is greater than the lower limit of the storage amount set in step S721 (step S722).

  In step S722, when the power control unit 101e determines that the power storage rate is greater than the lower limit of power storage amount (step S722; YES), the power control unit 101e performs the same processing as steps S501 and S502 in FIG. Then, control for discharging the storage battery 98a of the EV 98 is performed (steps S723 and S724). Thereafter, the prediction unit 101g recalculates the insufficient power (that is, the value obtained by reversing the sign of the surplus power) using the above equation (1) (step S725). Thereafter, the predicting unit 101g determines whether or not the recalculated value of the insufficient power is a positive value (that is, whether or not there is a power shortage) (step S726). At this time, if it is determined that the value of the insufficient power is a positive value (step S726; YES), the power control unit 101e executes the processes of steps S507 and S508 in FIG. 24 as necessary. After reducing the power consumption of the electrical device 20 (step S727 and step S728), the execution of the normal storage process is terminated. On the other hand, when the power control unit 101e determines that the recalculated power shortage value is equal to or less than the value “0” (that is, power shortage has not occurred) (step S726; NO), After sending a command to the power conditioner 50 as necessary after the command to reduce the power purchased from the company or the power discharged from the storage battery 98a by surplus power (that is, a value obtained by reversing the sign of the insufficient power) The execution of the process during power storage is terminated.

  In step S722, when the power control unit 101e determines that the storage rate is equal to or lower than the lower limit of storage amount (step S722; NO), the power control unit 101e performs control to stop the discharge of the storage battery 98a of the EV 98 as necessary. After performing (step S729), the execution of the normal power storage process is terminated.

  As a specific example, the control unit 101 determines that power is insufficient from time t1 to time t3 as shown in FIG. 29 (see step S704 in FIG. 26; NO). Next, the control unit 101 suddenly supplies power to each electric device 20 by discharging the storage battery 98a of the EV 98 from time t1 to time t2 (see step S723 in FIG. 27). After that, at time t2, the control unit 101 determines that the storage rate of the storage battery 98a is equal to the planned minimum use rate (70%), so that further discharge prevents the planned use of the EV 98 from being discharged. Stop (see step S722; NO).

  Thereafter, at time t3, the control unit 101 determines that the generated power is greater than the total power consumption but is in a steady state where the power surplus state has not been reached (step S707 in FIG. 26; refer to NO). The storage battery 98a is charged until the storage rate of the storage battery 98a becomes equal to the steady state preferable storage rate at time t4 (see steps S709 and S711).

  Thereafter, at time t5, the control unit 101 predicts that a power peak will occur (falls into a power shortage state) during a period from time t7 to t9 (see step S705; YES). Next, in preparation for the peak of power shortage, the control unit 101 charges the battery 98a until the power storage rate of the storage battery 98a becomes equal to the preferred power storage rate (100%) at the time of power shortage at time t4 (steps S706 and S711, etc.). reference). At time t7, the control unit 101 determines that power is insufficient (step S704; see NO), and discharges the storage battery 98a from time t7 to t8 (see step S723 in FIG. 27). Thereafter, at time t8, it is determined that the storage rate of the storage battery 98a is equal to the planned minimum use rate, and discharging is stopped (see step S722; NO and step S729).

  From time t9 to t10, the control unit 101 executes processing similar to the processing from time t3 to t5, respectively. At time t10, the control unit 101 determines that the power control system 1 is in a power surplus state (step S707 in FIG. 26; YES), and charges the storage battery 98a to a suitable power storage rate (80%) at the time of power surplus (FIG. 26, step S708, etc.).

  At time t11, control unit 101 determines that EV 98 is not used for a long period of time (see step S414 in FIG. 23; see YES), and discharges it to a suitable storage rate (20%) when not in use for a long period of time (see step S416). ).

  If it is determined in step S401 in FIG. 22 that the EV 98 is not connected to the power conditioner 50 (step S401; NO), the control unit 101 executes an EV non-connection power control process as shown in FIG.

  When the EV unconnected power control process in FIG. 28 is started, the calculation unit 101d and the prediction unit 101g execute the same processes as steps S502 and S503 in FIG. 24 (steps S731 and S732), respectively. Next, the prediction unit 101g executes surplus power prediction processing for predicting surplus power in a period after a predetermined time from the current time when there is no power supply from the EV 98 using the following equation (5) (step S733). ).

  Surplus power = Generated power + Threshold of power system 99-Total power consumption (5)

  Thereafter, the power control unit 101e performs the same processing as the processing from Steps S506 to S508 in FIG. 24 (Steps S734 to S736), and suppresses the power consumption of the power device 20 as necessary. The connection power control process is terminated.

  According to these configurations, for any one or more of the plurality of electrical devices so as to try to suppress the power consumption based on the predicted power predicted using the pattern of the total power consumption in the identified life scene. Therefore, the power consumption can be suppressed before the total power consumption of the plurality of electric devices becomes large.

Moreover, according to these structures, the electric power control part 101e is charging / discharging with respect to the storage battery 98a mounted in EV98 based on the predicted value of the generated electric power in the period specified by the specific | specification part 101a, and the estimated electric power about total power consumption. And controlling the total power consumption based on the predicted value of charge / discharge power and the predicted value of generated power. For this reason, the difference between the amount of power generated during the predetermined period and the total power consumption can be further reduced. That is, since the amount of CO ₂ discharged for generating the electric power consumed by the power control system 1 can be further reduced, a low CO ₂ house can be realized and contribution to the achievement of zero emission.

Furthermore, according to these configurations, the power control unit 101e determines that the storage battery 98a mounted on the EV 98 is not deteriorated or the deterioration degree of the storage battery 98a is smaller than a predetermined degree based on the predicted value of the power consumption in the EV 98. Thus, the storage battery 98a is charged and discharged. For this reason, since the deterioration of the storage battery 98a mounted on the EV 98 can be prevented, the difference between the amount of power generated during the predetermined period and the total power consumption can be reduced while suppressing the decrease in the convenience of the EV 98 ( (In other words, a low CO ₂ house can be realized)

Furthermore, according to these configurations, the power control unit 101e includes the first storage amount (when the storage battery 98a mounted on the EV 98 is not deteriorated due to overdischarge or the degree of deterioration due to overdischarge is smaller than a predetermined amount (when the battery is not used for a long time). The second power storage amount (minimum power storage rate when scheduled to be used) obtained by adding a predicted value for the power consumption amount of EV 98 to the suitable power storage rate) is the same as the power storage amount (power storage rate) of the storage battery 98a or the second When the amount of electricity stored is less than the amount of electricity stored (minimum electricity storage rate when scheduled to be used), discharging of the storage battery 98a is stopped. For this reason, since the storage battery 98a accumulates more electric power than the predicted electric power consumption of the EV 98, the difference between the electric power generated during the predetermined period and the total electric power consumption is reduced (that is, a low CO ₂ house). Even when the storage battery 98a included in the EV 98 is discharged in order to achieve the above, it is possible to prevent the convenience from being lowered by inhibiting the use of the EV 98. Further, if EV 98 is actually used as predicted, the storage amount (storage rate) of storage battery 98a mounted on EV 98 does not fall below the first storage amount (preferred storage rate when not in use for a long period of time). Can be prevented from deteriorating.

  Further, according to these configurations, the power control unit 101e is larger than the second power storage amount (minimum power storage rate when scheduled to be used) and does not deteriorate or exceed even if the storage battery 98a is not discharged beyond the overcharge limit time. The third storage amount (preferred storage rate at steady state) in which the degree of deterioration due to charging is smaller than a predetermined level and the storage amount (storage rate) of the storage battery 98a are the same or the third storage amount (preferred storage rate at steady state). If it is less, charging of the storage battery is stopped. For this reason, even when the EV 98 is not used as predicted or when the storage battery 98a is not discharged beyond the overcharge limit time, it is possible to prevent the storage battery 98a mounted on the EV 98 from deteriorating. .

Furthermore, according to these configurations, when it is predicted that the power surplus state will occur, the power control unit 101e has a storage battery that is larger than the third power storage amount (preferred power storage rate at normal time) and within the overcharge limit time. The fourth power storage amount (preferred power storage rate at the time of surplus power) in which 98a does not deteriorate or the degree of deterioration becomes smaller than a predetermined level is the same as the power storage amount of the storage battery 98a or the fourth power storage amount (preferred power storage rate at the time of power surplus) ), The charging of the storage battery 98a is stopped, and the storage amount (storage rate) of the storage battery 98a is the same as the fourth storage amount (preferred storage rate when surplus power) or the fourth storage amount. The storage battery 98a is discharged before the time during which the amount of stored electricity (storage rate) is greater than (the preferable storage rate when surplus power) exceeds the overcharge limit time. For this reason, it is possible to prevent deterioration of the storage battery 98a while realizing a low-CO ₂ house by surplus power stored in the storage battery 98a of the EV 98.

Furthermore, according to these configurations, when it is predicted that a power shortage state will occur, the power control unit 101e is greater than the third power storage amount (preferred power storage rate in a steady state) and is a preparation time for power shortage. The fifth storage amount (power storage rate) when the storage battery 98a is not deteriorated or the degree of deterioration is smaller than a predetermined level and the storage amount (storage ratio) of the storage battery 98a are the same or the fifth storage amount (electric power) The charging of the storage battery 98a is stopped when the storage amount becomes higher than the storage amount (storage rate), and the storage amount (storage rate) of the storage battery 98a is the same as the fifth storage amount (preferred storage rate at power shortage) (storage rate) or The storage battery 98a is discharged before the time during which the storage amount (storage rate) larger than the fifth storage amount (preferred storage rate at the time of power shortage) exceeds the preparation time for power shortage is exceeded. For this reason, by solving the power shortage by the electric power stored in the storage battery 98a of the EV 98, it is possible to prevent deterioration of the storage battery 98a while realizing a low CO ₂ house.

  Further, according to these configurations, the power control unit 101e does not deteriorate the storage battery 98a even when the storage battery 98a mounted on the EV 98 is not discharged during the non-use period, or the degree of deterioration becomes smaller than a predetermined level. The storage battery 98a is charged until the storage battery 98a reaches a storage capacity (storage ratio) that is small enough so that the storage battery 98a does not deteriorate even if the storage battery is not charged during the non-use period. Or it is made to discharge and charging / discharging of the storage battery 98a is not controlled in a non-use period. For this reason, since EV98 is not used over a non-use period, even if it is a case where the storage battery 98a does not discharge, deterioration of a storage battery can be prevented reliably.

<Modification of Embodiment 2>
If it is determined in step S704 of FIG. 26 that the surplus power is a positive value (step S704; YES), the power control unit 101e orders the discharge to end if the storage battery 98a is being discharged. After the command is transmitted to the power conditioner 50, the upper limit of the storage rate of the storage battery 98a is set to 100 regardless of whether or not the peak of insufficient power comes and whether or not the power control system 1 is in the surplus generated power state. % (Or, for example, a value obtained by subtracting a predetermined value from 100%, such as 98%), and until the storage rate of the storage battery 98a reaches 100% (or 98%) in Step S711 (that is, the storage battery 98a is A configuration in which charging is performed (until fully charged) can be employed.

  That is, the power control unit 101e starts full charging of the storage battery 98a when power is surplus (see step S704; YES), and when a predetermined time elapses after the storage battery 98a is fully charged (more precisely, storage of power When the time when the overcharge limit time elapses after the rate exceeds 70% or the time when the preparatory time for power shortage elapses after the power storage rate exceeds 80%, whichever comes first) (step S420; YES and Step S421; see YES), overcharge elimination processing may be executed (see Step S422). In other words, the control unit 101 may repeat the full charging and discharging of the storage battery 98a at a predetermined time interval in which the storage battery 98a does not deteriorate or the degree of deterioration that occurs is less than a predetermined level.

According to these configurations, the power control unit 101e charges the storage amount of the storage battery 98a mounted on the EV 98 to the full charge amount or to a storage amount that is smaller than the full charge amount by a predetermined amount of power. The storage battery 98a is discharged before the full charge amount or the amount of stored electricity less than the full charge amount is maintained even if the charge amount is not deteriorated or the degree of deterioration exceeds a predetermined time less than the predetermined amount. For this reason, it is possible to reliably prevent the use of the EV 98 due to a decrease in the amount of stored electricity while reliably preventing the deterioration of the storage battery, and thus the convenience of the EV 98 is reliably improved. Furthermore, it is possible to reliably prevent the realization of a low-CO ₂ house due to a decrease in the amount of generated power that is accumulated.
