(Processing flowchart)
9 and 10 are processing flowcharts of the power sale promotion mode according to Embodiment 1 of the present invention. This processing flowchart is stored in advance in a storage unit such as the memory 472 of the data server 300 as a program, and the CPU 470 reads out the program from the storage unit and executes it, thereby realizing processing according to the flowchart. The processes of FIGS. 9 and 10 are periodically repeated for each user.

  Referring to FIG. 9, first, CPU 470 determines whether or not an electricity bill unit price is set for the user's house (step S <b> 1). Specifically, the management table MT is searched to determine whether or not the electricity bill unit price 21A is set in the record 10 of the user. If it is set (YES in step S1), the process proceeds to step S3. If it is not set (NO in step S1), a message “Please set the unit price for electricity” is sent to the home controller 100. To do. The home controller 100 displays the received message on the display 102 and changes the screen to the unit price setting screen (step S11).

  In step S3, the CPU 470 searches the management table MT and determines whether or not the power selling unit price 21B is set in the record 10 of the user (step S3). If it is set (YES in step S3), the process proceeds to step S5, but if it is not set (NO in step S3), a message “Please set power selling unit price” is sent to the home controller 100. To do. The home controller 100 displays the received message on the display 102 and shifts the screen to the power sale unit price setting screen (step S13). When the unit price is set in the management table MT in step S11 or S13, the process returns to step S1.

  In addition, the CPU 470 acquires (reads) the device list 24 from the record 10 of the user in the management table MT (step S5).

  CPU 470 determines whether or not the current time corresponds to the mode execution time zone stored in memory 472 from the time data counted by timer 475 (step S7). If it is determined that it corresponds to this mode execution time zone (YES in step S7), the process proceeds to step S9. If it is determined that it does not correspond (NO in step S7), step S7 is repeated to promote the power sale mode. Is not implemented. Therefore, it is possible to limit the power sale promotion mode so that the power sale promotion mode is not mistakenly performed during the mode execution time period, that is, at night when power sale (power generation) cannot occur.

  If it is determined that it is in the mode execution time zone, the determination unit 2 of the CPU 470 determines whether or not the power sale promotion mode can be performed, whether or not the conditional expression (PV> 0 and P ≧ threshold) is satisfied. That is, it is determined from surplus power information of solar power generation (step S9). Regarding the conditional expression, the threshold value = 0, and the variable PV and the variable P indicate the average power generation amount 22A and the average power sale amount 22B read from the record 10 of the management table MT. When the conditional expression is satisfied, that is, at least during a period when power generation is performed and there is a possibility of power sale, the processing for automatic control and power saving advice output in FIG. 10 is performed for each of the electric devices 200A to 200D. . The threshold value of the conditional expression is not limited to 0, and the conditional expression itself can be changed.

  When it is the mode execution time zone and the above conditional expression is satisfied (the power sale promotion mode can be implemented), the CPU 470 individually performs the processing of FIG. 10 for each of the electric devices 200A to 200D. And it is repeated periodically.

  In the process of FIG. 10, a flag F and a flag T are used to indicate whether or not automatic control according to the automatic control A information 28 or the automatic control B information 29 is being executed for the electric devices 200 </ b> A to 200 </ b> D. The initial values of these flags are 0, and 1 indicates that automatic control is being executed. When the user manually controls the electric device by operating the remote controller or the like, the CPU 470 receives the operation setting information after manual control of the electric device from the home controller 100, and the corresponding operation setting in the device list 24. The information 27 is rewritten with the received operation setting information, and the flag F (or T) is set to 0.

  Here, the processing in FIG. 10 will be described for the case where the air conditioner (electric device 200D) is controlled, but the same processing can be performed even when other electric devices are controlled.

  First, the CPU 470 performs the processing from step S23 onward while determining the mode execution time zone (step S21). In step S23, the determination part 2 determines whether said conditional expression is satisfied (step S23). In step S23, it may be determined whether or not the conditional expression is continuously established a predetermined number of times.

  If it is determined that the conditional expression is not satisfied (NO in step S23), that is, if the average power generation amount 22A indicates 0 or less, or there is no surplus power and the average power sales amount 22B indicates less than the threshold value (= 0), the routine R2 To implement. Routine R2 is a process for encouraging power saving when there is a large amount of power purchase, and details will be described later. On the other hand, if it is determined that the above conditional expression is satisfied (YES in step S23), a routine R1 for further promoting power saving (power selling) during power selling is executed.

  In the routine R1, first, in step S25, the CPU 472 determines whether or not automatic control of the air conditioner (electric device 200D) is valid from the automatic control presence / absence data 26 of the device list 24 (step S25). If it is determined that it is not valid (NO in step S25), the advice acquisition unit 6 acquires “advice A” for power saving (step S35). The acquired advice is transmitted to the home controller 100 by the notification unit 7 and displayed on the display 102.

  On the other hand, if it is determined that the automatic control of the air conditioner is valid (YES in step S25), it is determined whether or not it currently falls within an automatic control execution time zone in which automatic control execution of the electric devices 200A to 200D is permitted (step S27). ). In the first embodiment, it is assumed that the automatic control execution time zone is determined in advance as the time zone 6:00 to 17:00 in the mode execution time zone (3:30 to 19:30). Information on the automatic control execution time zone is stored in the memory 472 in advance.

  CPU 470 determines whether the time data from timer 475 corresponds to the automatic control execution time zone of memory 472 (step S27). If it is determined that this is the case (YES in step S27), automatic control A is performed for the air conditioner according to the corresponding automatic control A information 28 of the device list 24, and the CPU 470 sets 1 to the flag F (step S31).

  Specifically, the control execution unit 5 reads the automatic control A information 28 and transmits it to the home controller 100. The home controller 100 generates a control signal addressed to the air conditioner according to the received automatic control A information 28 and transmits the control signal via the repeater 160. The communication device 240D receives the control signal, generates a control parameter based on the control signal, and supplies the control parameter to the air conditioner (electric device 200D). The computer of the air conditioner changes the operation state of the air conditioner to the operation state of the target value according to the automatic control A information 28 by executing the program of the automatic control function using the control parameter. For example, by controlling to change the set temperature by 1 ° C. every 15 minutes until the target value is reached, for example, by increasing the set temperature at the time of cooling, the power consumption of the air conditioner can be saved. Can be increased.

  On the other hand, when CPU 470 determines that the time does not fall within the automatic control execution time zone (NO in step S27), whether or not the air conditioner is currently executing automatic control depending on whether or not (flag F = 1) is satisfied. Is determined (step S29). If it is determined that automatic control is being executed (YES in step S29), the air conditioner is controlled to return to the operating state before execution of automatic control (step S33).

  Specifically, the control execution unit 5 reads the operation setting information 27 from the management table MT and transmits it to the home controller 100. When home controller 100 generates and transmits a control signal in accordance with received operation setting information 27, communication device 240D receives the control signal, generates a control parameter based on the control signal, and provides it to the air conditioner (electric device 200D). The computer of the air conditioner returns the operation state from the operation state according to the automatic control A information 28 to the original operation state before the execution of the automatic control by executing the program of the automatic control function using the control parameter. For example, the set temperature is changed by 1 ° C. every 15 minutes until the set temperature reaches the target value indicated by the operation setting information 27. As a result, when the automatic control execution time period is not reached, the operation state of the air conditioner is automatically returned to the original state.

  When it is determined in step S25 that automatic control is not effective (NO in step S25), or when automatic control is not being executed, that is, it is determined that (flag F = 0) is satisfied (NO in step S29), the advice acquisition unit 6 Acquires “advice A” (step S35). The notification unit 7 transmits the acquired advice to the home controller 100. When the home controller 100 receives “Advice A”, it displays it on the display 102. The acquisition of “advice A” will be described later.

  Next, the routine R2 will be described. Routine R2 is basically the same processing as routine R1, and here, differences will be mainly described.

  If it is determined that the above conditional expression is not satisfied (NO in step S23), CPU 470 executes routine R2 for encouraging power saving when there is much power purchase.

  In the routine R2, it is first determined whether or not automatic control is effective from the automatic control presence / absence data 26 of the air conditioner (electric device 200D) (step S41). If it is determined that the automatic control is not effective (NO in step S41), an advice acquisition unit 6 acquires “advice B” (step S51). The notification unit 7 transmits the acquired advice to the home controller 100. The home controller 100 displays the received “advice B” on the display 102.

  On the other hand, if the CPU 470 determines that the automatic control is valid (YES in step S41), it determines whether or not it currently falls within the above-described automatic control execution time zone (step S43).

  If it is determined that it is the automatic control execution time zone (YES in step S43), the control execution unit 5 controls the air conditioner to execute the automatic control B according to the corresponding automatic control B information 29, and sets 1 to the flag T. Set (step S47).

  Specifically, the control execution unit 5 reads the automatic control B information 29 and transmits it to the home controller 100. The home controller 100 generates and transmits a control signal addressed to the air conditioner according to the received automatic control B information 29. The communication device 240D generates a control parameter based on a control signal from the home controller 100, and supplies the control parameter to the air conditioner (electric device 200D). The computer of the air conditioner executes the program of the automatic control function using the control parameter, and changes the operation state to the operation state of the target value according to the automatic control B information 29. For example, control is performed so that the set temperature is changed by 1 ° C. every 15 minutes until the set temperature reaches the target value. Therefore, when the set temperature during cooling is raised, the power consumption by the air conditioner can be suppressed.

  On the other hand, if it is determined that it does not fall within the automatic control execution time zone (NO in step S43), CPU 470 determines whether or not automatic control is being executed depending on whether or not (flag T = 1) is satisfied (step S43). S45). If it is determined that the automatic control is being executed (YES in step S45), the control execution unit 5 controls the air conditioner to return to the operation state before the automatic control as in step S29 (step S49).

  When it is determined that automatic control is not effective (NO in step S41), or when automatic control is not being executed, that is, when it is determined that (flag T = 0) is established (NO in step S45), the advice acquisition unit 6 “advises B ″ is acquired (step S51). The notification unit 7 transmits the acquired advice to the home controller 100. The home controller 100 displays “advice B” from the data server 300 on the display 102. The acquisition of “advice B” will be described later.

  Here, the power sale promotion mode in FIG. 8 is forcibly terminated when the user instructs to cancel the mode or when power purchase occurs, and the operating states of the electric devices 200 </ b> A to 200 </ b> D are based on the operation setting information 27. The operation state may be returned to. Further, when the above conditional expression is not satisfied after the execution of the automatic control is started, the control execution unit 5 switches the electric devices 200A to 200D to the original in accordance with the operation setting information 27 even in the mode execution time zone. Control is made to return to the operating state, and the display 102 outputs a notification to that effect. In addition, when the automatic control execution time period is not reached during execution of automatic control, the electric devices 200 </ b> A to 200 </ b> D are controlled to return to the original operation state according to the operation setting information 27 and a notification to that effect is output to the display 102. Note that the change in the operating state of the electric devices 200A to 200D does not include a change from turning off the power to turning it on.

(Get advice)
FIG. 11 is a diagram showing an example of the advice table according to the embodiment of the present invention. The advice tables 40A and 40B shown in FIG. 11 are created in advance and stored in a storage unit such as the memory 472 of the data server 300. The advice table 40A is a table storing advice data for promoting power saving during power sale, and is searched by the advice acquisition unit 6 in step S35 of the routine R1. The advice table 40B is a table storing advice data for promoting power saving during power purchase, and is searched by the advice acquisition unit 6 in step S51 of the routine R2.

  The advice table 40A indicates, for each of the advices corresponding to the electric devices 200A to 200D, the advice identification number 41, the category to which the advice belongs (in this case, “promotion of power sale”) 42, and whether the advice is output. One or more conditions 43 for determination, advice 44 corresponding to the first advice information including the above-mentioned “advice A”, and a device ID 45 for identifying an electrical device corresponding to the advice are included. The condition 43 includes different conditions 1 and 2 here. The conditions 1 and 2 are, for example, a time when advice should be output (May to October, etc.), and whether or not the corresponding electric device has an automatic control function. However, the present invention is not limited to these. The advice table 40B includes power saving advice corresponding to the second advice information, and has the same configuration as the advice table 40A. However, the category 42 is “promotion of power saving” as compared with the advice table 40A. It is different in that it shows. Other data is the same and the description will not be repeated here.

  The advice acquisition unit 6 acquires (reads out) the advice 44 by searching the advice table 40A or 40B. That is, if the advice 44 determined to satisfy the corresponding condition 43 is identified from the advice 44 corresponding to the device ID 45 indicated by the device name 25 of the corresponding electrical device (this is referred to as a hit), it has been hit. Read advice from the table. If no hit is found as a result of the search, a predetermined advice (for example, an advice having an identification number 41 of “1” in the advice table 40A) may be read and output.

  As a result, advice for promoting power sale is acquired during the power sale for executing the routine R1, and advice for promoting power saving is acquired during the power purchase for performing the routine R2, and is displayed on the display 102 and notified to the user. Can do.

[Embodiment 2]
In the second embodiment, a modification of the first embodiment will be described. In the second embodiment, a configuration for preventing an excessive burden on power saving will be described.

  In the first embodiment, when the conditional expression (automatic control execution time zone and (PV> 0) and (P ≧ threshold)) is satisfied, automatic control of the power sale promotion mode by the routine R1 is executed. The value indicated by P used in the equation is not limited to the amount of power sold (unit: Wh). For example, the surplus power information is indicated by using a calculated value of P = (amount of electricity sold × a unit price of electricity sold) − (amount of electricity purchased × a unit price of electricity purchased) using the electricity unit price 21A and the electricity sale unit price 21B of the management table MT. May be. When this calculated value is used in the above conditional expression, automatic control of the power sale promotion mode is executed during the period when the power sale profit is generated. Therefore, in the second embodiment, the automatic control execution time period does not become longer compared to the case where P is the amount of power sold (unit: Wh) as in the first embodiment, and the user has an excessive burden related to power saving. This can be prevented.

  In addition, a condition “automatic control execution time zone” is added to the condition 43 of the advice tables 40A and 40B, and the advice in steps S35 and S51 is based on the automatic control execution time zone (6: 0 to 17:00). ) Only during the period corresponding to This limits the period during which the advice is output and prevents an excessive burden on power saving.

  The automatic control A information 28 includes a plurality of patterns having different power saving effects, and is selected from the plurality of patterns of the automatic control A information 28 according to the value of P. Thereby, automatic control of different target values according to the magnitude of the value of P is performed, and an excessive burden on power saving is prevented.

  Specifically, when the condition (P> threshold) is satisfied, the same processing as that of the first embodiment is executed, but the time period when the condition (P≈threshold) is satisfied, that is, the amount of power sold and the amount of power purchased are antagonized. The pattern of the automatic control A information 28 for further encouraging power saving is selected only during the time period during which it is running. In addition, when (amount of power sold≈amount of power purchased), another pattern of the automatic control A information 28 for further promoting power saving is selected. In this case, a message stating “Power saving will occur if power is saved now” is output to the display 102, and the automatic control content is changed according to the selected pattern only when the user consents after the notification. To do. When the condition (P ≧ threshold value) is satisfied at the next timing, the operation setting information is returned to the original set value. Thereby, when the user's consent is obtained, automatic control for further power saving is executed, so that it is possible to prevent an excessive burden on the user regarding power saving.

  The automatic control A information 28 may also output different advice corresponding to each of the plurality of patterns to prevent an excessive burden on the user regarding power saving. That is, the advice acquisition unit 6 acquires different advice information according to the magnitude of the power value indicated by the surplus power information, and the notification unit 7 notifies at an interval that does not become a burden (for example, once every 30 minutes). To do. The advice is obtained from the following group A or group B and notified. The notification interval can be variably set by the user.

  [Group A]: Advice output when the condition P ≧ threshold value (the power sale exceeds the power purchase) is satisfied. For example, the advice 44 described in the advice table 40A is included.

  [Group B]: The content of advice is selectively switched according to the value of P. For example, it includes advice that outputs a target value (such as a set temperature of an air conditioner) when the condition P <threshold (electric power purchase exceeds electric power sale) is satisfied.

  It should be noted that the power saving effect is great in the time zone in which the routine R2 is performed with a large amount of purchased power, and the advice may be output only during this time zone.

[Embodiment 3]
In the third embodiment, a modification of the first or second embodiment will be described. In the third embodiment, unlike the first and second embodiments, the mode execution time zone is determined from past performance data. FIG. 12 is a diagram showing an example of the weather table 30 for determining the mode execution time zone according to the third embodiment.

  In the third embodiment, similarly to the first embodiment, the processing shown in FIGS. 9 and 10 is performed, but the mode execution time zone is variably determined from the information in the weather table 30. The mode execution time zone determination unit 3 determines the time zone from the above-described sunrise and sunset times that allow solar power generation, but the change unit 4 changes this from the weather table 30 of FIG. The weather table 30 in FIG. 12 is stored in a storage unit such as the memory 472 of the data server 300. The weather table 30 indicates the date data 31 and the actual (actual) weather (sunny, cloudy, rainy) for each day in the past certain period (last 28 days or one month) in the user's home area. Information 32 and P trend data 33 are included. The weather information 32 indicates information received from the weather company server 360. P trend data 33 indicates time series data of P (power sales) values calculated from power information that the data server 300 periodically receives from the home controller 100 of each user's home in the area.

  With reference to the weather table 30, for example, a method for determining the mode execution time zone for today (June 29) will be described. Here, it is assumed that today's weather forecast received from the weather company server 360 is “sunny”. The CPU 470 of the data server 300 identifies in the weather table 30 that the corresponding weather information 32 indicates “sunny” that is the same as the forecast for today and the corresponding date data 31 indicates the most recent date. Then, P trend data 33 corresponding to the identified date data 31 is read from the weather table 30. Then, from the read trend data 33 of P, a time zone in which power sale is occurring is detected, and the detected time zone is determined as a mode execution time zone for today. Therefore, according to the weather table 30 of FIG. 12, today's mode execution time zone is determined from the P trend data 33 on June 26. Note that the start time may be constant in the mode execution time zone, and only the end time may be determined from the actual data in the weather table 30. As described above, by using the weather table 30, it is possible to determine the mode execution time zone based on the region-specific topography or weather.

  As a modified example of the method for determining the power sale mode execution time zone using the weather table 30, the following method 1 or method 2 will be described.

(Method 1)
The valid data in the weather table 30 is data for the past month. Specifically, data valid before the past month is deleted from the weather table 30 to store only valid data in the weather table 30. Thereby, the mode execution time zone can be determined with reference to the effective data in consideration of seasonal variation and the like.

  Further, when there is no data of the weather information 32 that matches the forecast weather of the day, the mode execution time zone is determined with reference to replaceable data. For example, if the forecast for the current day is “rain” and “rain” data is not registered in the weather table 30, it is determined from the data on the latest “cloudy” day. Similarly, when the forecast is “cloudy” and there is no “cloudy” day data in the weather table 30, it is determined from the most recent “clear” day data. Similarly, when the forecast is “sunny” and there is no data on a “clear” day in the weather table 30, it is determined from the data on the most recent “cloudy” day.

(Method 2)
In this method 2, the power sale mode execution time zone is determined from the correlation information between the weather forecast and the results. In method 2, not only the actual data for each date of weather but also the forecast data for that day is registered in the weather table 30 in FIG. 12, and the mode execution time zone is determined from the correlation information between the forecast and the actual results. For example, a method of determining the mode time zone for today (June 29) will be described. It is assumed that today's forecast was “clear”. From the weather table 30, the ratio of days in which the actual result is “sunny” in the weather forecast “sunny” in the past month is calculated. That is, the probability that the weather forecast is hit is calculated, and when the calculated probability is high (for example, 30% or more), the end time of the mode execution time zone is determined from the trend data 33 of P on the most recent “sunny” day. However, if it is low (less than 30%), a predetermined time is determined as the end time. The predetermined time is a predetermined time corresponding to this period (period indicated by the date of the weather table 30).

  The end time of the mode execution time zone from the weather table 30 can be determined as follows, for example. That is, the latest time among the times satisfying the conditional expression (PV> 0 and P ≧ threshold) from the corresponding P trend data 33 for each past actual weather (sunny, cloudy, rainy) is shown. You may decide. Then, at the point of time (P <threshold) after the scheduled end time, the execution of the power sale promotion mode is ended.

(Modification)
A modification of the first to third embodiments will be described.

  In the above-described embodiment, a message such as advice is displayed on the display 102. However, an audio output unit such as a speaker may be provided and output via this.

  The method for measuring the power consumption of each of the electric devices 200A to 200D is not limited to the method using the indoor distribution board described above. For example, each of the communication devices 240 </ b> A to 240 </ b> D may include a power sensor, measure power consumption of a corresponding home appliance by the power sensor, and transmit the measured power to the repeater 160.

  In the first to third embodiments, the mode execution time zone determination unit 3 determines the mode execution time zone from the sunrise / sunset time or the weather table 30, but the present invention is not limited to this, and the user operation accepted by the terminal 50 or the home controller 100 It can be changed based on the content. Specifically, in the mode execution time zone determined from sunrise and sunset, the changing unit 4 variably sets a time zone during which the power sale promotion mode is not executed (time zone during which execution is prohibited) based on an instruction from the user. Also good. For example, taking into account changes in the user's life time zone, etc., it is variably set according to changes in the life time such as day of the week (weekends, weekdays), weekly, seasonal, summer vacation, etc. Similarly, the automatic control execution time zone may be variably set in accordance with the fluctuation of the living time such as a day of the week (weekend, weekday), weekly, seasonal, summer vacation, etc. based on the contents of the user operation.

  Further, the determined mode execution time zone or automatic control execution time zone may be displayed on the display 102 to notify the user.

  Further, regarding the weather table 30, history information of the amount of power sold (or the amount of power sold) for each day when the power sale promotion mode is executed and when it is not executed is stored together with the weather information, and the weather table 30 is displayed on the display 102. Display information based on. The user can quantitatively confirm the power saving effect by executing the power sale promotion mode from the display information.

  The advice notification (output) acquired from the advice table 40A or 40B is output once every 30 minutes, but the output frequency can be changed.

  When the operation state is changed from the operation setting information 27 to the operation state according to the automatic control A information 28 or the automatic control B information 29, the setting contents of the operation state of the transition destination (the automatic control A information 28 or the automatic control B information 29) is displayed on the display 102 to notify the user. For example, it notifies that “the set temperature of the air conditioner has been changed to 28 ° C.”. In addition, after the notification is output, when the user operates the remote controller 200R to change the temperature setting, switching is performed so as to shift to another operation state with the changed set temperature as a target.

  When it is desired to stop (cancel) the execution of automatic control that makes a transition to an operation state according to the automatic control A information 28 or the automatic control B information 29, the user performs a stop operation from the tablet 103 or the remote control 200R. The instruction according to the operation content is accepted by the application program of the automatic control function of each of the electric devices 200A to 200D, and the automatic control execution is stopped. When automatic control execution is stopped, the electric device does not perform automatic control thereafter even in the mode execution time zone.

  Further, the operation setting information 27 set by the user by operating the remote control 200R or the like by the application program of the automatic control function of the electric devices 200A to 200D is the target value indicated by the automatic control A information 28 or the automatic control B information 29. If it is determined that a value that promotes power saving is shown, control is performed so as to maintain the current operating state of the electrical device without shifting to the operating state according to the automatic control A information 28 or the automatic control B information 29. .

  In the first to third embodiments, the notification destination of the advice or message from the data server 300 is the display 102 of the home controller 100, but is not limited thereto, and is transmitted to the terminal 50 carried by the user and displayed on the display unit. 53 may be displayed. FIG. 13 shows an example of display on the terminal 50. The CPU 54 receives the average power generation amount 22 </ b> A, the average power sales amount 22 </ b> B, and the average power consumption 22 </ b> C of the user read and transmitted from the management table MT by the data server 300, and displays them on the screen of the display unit 53. On the same screen, the data server 300 receives and displays the advice read and transmitted from the advice table 40A or 40B. In addition, on the same screen, the notification that the operation state is switched for the electric devices 200A to 200D or the operation setting information after the switching is received from the data server 300 and displayed. Although these pieces of information are displayed on the same screen, they may be displayed by switching to another screen.

  Although the processing of the first to third embodiments has been described on the assumption that the data server 300 functions as a controller that manages the power of each user's home, the home controller 100 or the terminal 50 has the same function, and these are stored in the user's home. It can function as a controller for managing power.

(Configuration of the embodiment)
In the embodiment, the controller that adjusts the input power input from the power system of the commercial power source and the output power output to the power system for supplying to the electric device is a power generation device for generating the power supplied to the electric device. The power information acquisition unit that acquires surplus power information indicating surplus power output to the power system from the generated power and the surplus power information are used to determine whether to increase the output power or decrease the input power When it is determined that the output power is increased by the determination unit and the determination unit, the first advice information for increasing the output power is used to decrease the input power when it is determined that the input power is decreased. An advice acquisition unit that acquires each of the second advice information and a notification that notifies the advice information acquired by the advice acquisition unit via the output unit And, equipped with a.

  Therefore, advice information regarding power saving can be given by notifying the acquired surplus power information of advice information on whether to increase the output power to the power system or decrease the input power from the power system. .

  When the determination unit determines that the output power is to be increased, the advice acquisition unit acquires different first advice information according to the magnitude of the power value indicated by the surplus power information. Therefore, it is possible to provide advice information for saving power step by step.

  The above configuration further includes a time determination unit that determines the time for notifying the advice information from the time during which the power generation apparatus can generate power. Therefore, advice information can be notified at the time when the power generation device generates power.

  The above configuration further includes an operation reception unit that receives a user operation, and the time determination unit determines a time for notifying the advice information from the time during which power generation by the power generation apparatus can be performed and the received user operation content. Therefore, the time for notifying the advice information can be determined from the contents of the user operation.

  In the above configuration, the weather information of the area where the power generation device is installed is acquired, and the time determination unit determines the time to notify the advice information from the time when the power generation device can generate power and the acquired weather information. . Therefore, it is possible to determine the time to notify the advice information from the local weather information.

  In the configuration described above, information on the time at which the advice information determined by the time determination unit should be notified is notified via the output unit. Therefore, the time when the advice information is notified can be notified.

  In the above configuration, the electrical device has a plurality of operating states with different power consumption, and when the determination unit determines to increase the output power or when it is determined to decrease the input power, The apparatus further includes a control execution unit that outputs information for controlling the electric device so as to change to a smaller operating state. Therefore, the power consumption of the electric device can be suppressed and power saving can be promoted.

  In the above configuration, when the operating state is changed, the change is notified via the output unit. Therefore, the user can recognize that the operation state is changed.

  In the above configuration, the time for outputting information for control by the control execution unit is variably determined. Therefore, the time during which the operating state of the electrical device is controlled by the control information of the control execution unit can be changed instead of being fixed.

(Effect of embodiment)
