Description

The present invention relates to a control device, power management system, control method and program.

In recent years, power generation facilities using natural energy such as sunlight and wind power have become widespread. Such power generation facilities are also introduced to small-scale consumers including general households as distributed power sources.

Power generation facilities using natural energy fluctuate in the amount of power generated depending on weather conditions. When the generated power exceeds the power consumed by the consumer, it becomes surplus power. In order to utilize such surplus power, a system that reversely flows the surplus power to a commercial grid power supply and sells the power is also widespread.

However, an imbalance in supply and demand due to reverse power flow may cause voltage fluctuations, power outages, and the like in the commercial system power supply. For this reason, systems that perform control to restrict reverse power flow to a system power supply under certain conditions, systems that store surplus power that cannot be reversed in a power storage device, and the like are known.

However, during the period when the reverse power flow to the system power supply is restricted or during the period when the power storage amount of the power storage device reaches the rated capacity value, it is not possible to utilize any more surplus power. Various proposals have been made to utilize such surplus power.

For example, Patent Literature 1 discloses a power control system that automatically controls electrical equipment and consumes the surplus power when there is a surplus of power generated using natural energy. Patent Literature 2 discloses a system that displays a message prompting power consumption when the estimated amount of surplus power exceeds the free capacity of a storage battery. Patent Literature 3 discloses a system that notifies a consumer of a time period during which reverse power flow to a system power supply is restricted, and encourages the consumer to consume power during the restricted time period.

In the system disclosed in Patent Literature 1, there are cases in which an electrical device that is automatically controlled to consume surplus power is not the device that the user actually wants to use. Therefore, convenience is reduced.

The system disclosed in Patent Literature 2 is configured to prompt power consumption when the predicted surplus power amount exceeds the free capacity of the storage battery. Therefore, it cannot be applied to an environment without a storage battery. In an environment with a storage battery, surplus power can be stored, but in an environment without a storage battery, surplus power cannot be stored, so there is a greater need to use surplus power in real time. Moreover, using surplus power in real time reduces wasteful losses and increases the efficiency of using surplus power rather than storing surplus power in a storage battery.

In the system disclosed in Patent Document 3, only the time zone in which the reverse power flow to the grid power supply is restricted is notified, and it is not considered whether or not there will be a surplus of electric power during that time zone. Therefore, there is a problem that self-consumption is encouraged even when surplus power is not actually generated. Moreover, there is also a problem that it cannot be applied to an environment that is not connected to a system power supply.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a control device, a power management system, a control method, and a program that are convenient and highly efficient in using surplus power.

To achieve the above object, a control device according to the present invention includes a power information acquisition unit, a weather information acquisition unit, a consumption pattern prediction unit, a power generation amount prediction acquisition unit, a surplus power prediction unit, and a control execution unit. , and a storage unit. The power information acquisition unit acquires power information indicating power consumption in the consumer from the current measuring device. The weather information acquisition unit obtains weather information including date and time information indicating a past or current time period and weather conditions in the past or current time period, date and time information indicating a future time period, and forecasting in the future time period. obtain weather forecast information including expected weather conditions; The consumption pattern prediction unit predicts a future power consumption pattern in the consumer based on weather information, power information acquired in a time period close to the date and time information included in the weather information, and weather forecast information. The power generation amount prediction acquisition unit acquires prediction information on future power generation of the power generation equipment in the customer. The surplus power prediction unit predicts surplus power that will occur in the future based on the consumption pattern predicted by the consumption pattern prediction unit and the prediction information of generated power obtained by the power generation amount prediction obtaining unit. The control execution unit controls the notification device to notify the time zone in which the surplus power predicted by the surplus power prediction unit occurs and the magnitude of the surplus power. The storage unit stores notification validity information indicating whether or not the notification device will perform notification, and a notification method indicating by what method the notification device will perform notification. The control execution unit controls the notification device according to the notification method at a predetermined time before the scheduled time at which the surplus power predicted by the surplus power prediction unit disappears when the notification effective information is valid. .

INDUSTRIAL APPLICABILITY The present invention performs control that does not depend on the available capacity of the power storage device, and therefore can be applied to an environment where there is no power storage device. In addition, since the notification device notifies the generation time of the surplus power, the user is urged to use the power, and the surplus power can be effectively utilized. Since the surplus power is used in real time, wasteful loss is reduced compared to the case where the surplus power is stored in the power storage device and used, and the surplus power can be used more efficiently. In addition, since the configuration is not such that power is used for preset devices, the user can select desired electrical devices and use power.

Therefore, according to the present invention, it is possible to improve the convenience and the efficiency of using the surplus power of the power generation equipment.

In this case, since the reference date and time information is obtained from the server device 900, there is an advantage that the date and time information does not need to be set in the initial settings.

The storage unit 140 includes, for example, RAM (Random Access Memory) and ROM (Read Only Memory). The storage unit 140 stores various data including a program used for control processing described later, control information described later, performance information, and the like.

A functional configuration of the control unit 110 will be described below.

By executing programs, the control unit 110 includes a power information acquisition unit 111 that acquires power information, a weather information acquisition unit 112 that acquires weather information and weather forecast information, a consumption pattern prediction unit 113 that predicts consumption patterns, It functions as a power generation amount prediction acquisition unit 114 that acquires prediction information on the power generation amount, a surplus power prediction unit 115 that predicts surplus power, and a control execution unit 116 that controls the notification device 400 to perform a notification operation.

In the following description, "acquisition" refers to obtaining information directly by receiving it from an external device, and indirectly obtaining information by performing arithmetic processing on the basis of a signal received from an external device. It shall include the case of obtaining "Prediction" includes a case of obtaining by receiving prediction information from an external device and a case of prediction by performing arithmetic processing by the own device.

The power information acquisition unit 111 acquires power information indicating power consumption in the consumer. Specifically, the power information acquiring unit 111 acquires power information by receiving measurement data of the power measuring device 312 of the distribution board 300 via the communication unit 120 . Also, the power information acquisition unit 111 acquires the generated power by receiving measurement data of the power generation meter 322 of the distribution board 300 via the communication unit 120 .

The weather information acquisition unit 112 acquires past or present weather information and weather forecast information. Specifically, weather information acquisition unit 112 acquires weather information by receiving weather information from server device 900 via communication unit 120 . The weather information acquisition unit 112 acquires weather forecast information by a similar method.

The weather information includes date and time information indicating the time period and the weather conditions for that time period, such as January 3, 16:00 to 18:00, the weather is clear, and the temperature is 23°C. be The weather forecast information includes date and time information indicating a future time period and weather conditions predicted for that time period.

The consumption pattern prediction unit 113 predicts the power consumption in the consumer for a predetermined future period based on the power information and the weather information stored in the storage unit 140 and the weather forecast information acquired by the weather information acquisition unit 112. predict the consumption pattern of Specifically, consumption pattern prediction unit 113 searches storage unit 140 for weather information having weather conditions similar to the weather conditions indicated by the weather forecast information, and predicts the power consumption indicated by the power information associated with the weather conditions in the future. power consumption.

The consumption pattern prediction unit 113 predicts future power consumption patterns by obtaining such operations over a predetermined period. The predetermined period is set, for example, to an integral multiple of the time period of the date and time information included in the weather information.

Note that the consumption pattern prediction method is not limited to a specific method, and any method can be used. For example, consumption patterns may be predicted by weighting various parameters. As various parameters, date and time information and weather information included in the performance information, types of connected notification device 400 and electric device 500, and the like may be used.

For example, if the date and time information is 1/5, 4:00 to 6:00, and the weather information is snow, it is understood that the environment is cold and the user is sleeping. Therefore, in the notification device 400 and the electrical device 500, the power consumption can be predicted by weighting the ratio of the air conditioner, the ratio of the devices that the user does not use while sleeping, and the like. Moreover, you may predict using the machine learning which feeds back the result of having compared the prediction and the actual result.

The power generation amount prediction acquisition unit 114 acquires prediction information on the power generation that the power generation equipment 200 in the customer's house will generate at a predetermined time in the future. Specifically, the power generation amount prediction acquisition unit 114 acquires the prediction information by receiving the prediction information distributed from the server device 900 via the communication unit 120 .

For example, information such as the region to which the consumer belongs, the specifications of the power generation equipment 200, and the installation conditions is stored in the storage unit 140 in advance. The power generation amount prediction acquisition unit 114 requests the server device 900 for prediction information that matches the conditions indicated by the information stored in the storage unit 140 . The server device 900 returns prediction information in response to this request. Thereby, the power generation amount prediction acquisition unit 114 acquires the power generation amount prediction information.

Based on the power consumption pattern predicted by the consumption pattern prediction unit 113 and the generated power prediction information obtained by the power generation amount prediction obtaining unit 114, the surplus power prediction unit 115 predicts the timing of occurrence of surplus power and the amount of surplus power. Predict size. Specifically, the surplus power prediction unit 115 determines the amount of surplus power to be a value obtained by subtracting the power consumption indicated by the power consumption pattern from the generated power indicated by the prediction information.

The control execution unit 116 controls the notification device 400 to notify the time zone and the magnitude of the surplus power predicted by the surplus power prediction unit 115 . Specifically, control execution unit 116 generates a control signal for causing notification device 400 to perform the notification operation. Note that the control signal is generated by referring to control information stored in the storage unit 140 in advance. Control execution unit 116 transmits the generated control signal to notification device 400 via communication unit 120 . The notification device 400 performs a notification operation in response to the received control signal.

The performance information and control information stored in the storage unit 140 described above will be described below.

As shown in FIG. 6, the performance information includes date and time information indicating the date and time, weather information indicating the weather, temperature, and humidity at the date and time indicated by the date and time information, and power consumption in the customer at the date and time indicated by the date and time information. contains. The performance information is displayed in chronological order based on hourly date and time information.

FIG. 6 is an example, and is not limited to this. For example, date and time information may be indicated in units of years or seconds, and weather information may include wind power, wave power, rainfall, wind direction, wind speed, amount of solar radiation, and the like. In any case, it is preferable that the performance information includes weather information that greatly affects the power generation amount of the power generation equipment 200 . The interval of date and time information is not limited to every hour, but may be every 30 minutes, every 3 hours, or the like.

The control information is, as shown in FIG. 7, information including the device type, identification number, notification method, and notification validity. The device type is information indicating the type of the notification device 400 . The identification number is information used as a destination when control device 100 transmits a control signal to notification device 400 . The notification method is information indicating by what method the notification unit 430 of the notification device 400 performs notification. Notification valid is information indicating whether or not notification device 400 performs notification when a control signal is received.

When the effective notification is "effective", the notification operation is executed according to the notification method. In addition, even when a plurality of notification devices 400 of the same type are registered, in order to make it possible to specify those notification devices 400, a column of identification names is added to the control information, and the user can arbitrarily assign each notification device 400. An identification name may be set.

In the example of FIG. 7, the device types include television, mobile phone, and PC (personal computer). For the television, the identification number is the IP address, the notification method is character display, and the notification is valid.

In this case, the control information is sent to the IP address, and the television notifies it by character display. For the mobile phone, the identification number is the phone number, the notification method is short mail, and the notification is valid. In this case, the control information is sent to the mobile phone as a short mail, and the mobile phone notifies by the short mail. For the PC, the identification number is an e-mail address, the notification method is e-mail, and the notification valid is invalid. In this case, no control information is sent to the PC and no notification is performed.

Devices that can be used as the notification device 400 are not limited to televisions, mobile phones, and PCs. The notification device 400 may be any device that can transmit information to at least one of human vision, hearing, and touch.

For example, if the notification device 400 is a stereo device or a radio, the notification may be made by voice. If the notification device 400 is a remote control device having a two-way communication function and a display screen, the notification may be performed by displaying character information on the display screen.

In the example of FIG. 7, character display, short mail, and e-mail are exemplified as notification methods. However, the notification method is strictly the information necessary to generate the signal that activates each notification function. For example, in the transmission of electronic mail, the information is mail header information such as character encoding, sender's mail address, and mail subject. Although these specific contents are not shown in FIG. 7, they are actually information included in the notification method.

So far, the configuration of each device included in the power management system 1 has been described. Hereinafter, the control processing executed by the control device 100 will be described with reference to FIGS. 8 to 10. FIG. Note that this control process is executed when the control device 100 is activated.

First, the control unit 110 of the control device 100 determines whether or not the current date and time kept by the time keeping unit 130 is the first processing time (step S101). The first processing time is the time at which the performance information is stored in the storage unit 140, and is, for example, every hour at 0:00.

When the control unit 110 of the control device 100 determines that it is the first processing time (step S101; Yes), the control unit 110 of the control device 100 executes performance information storage processing (step S102). When the control unit 110 of the control device 100 determines that it is not the first processing time (step S101; No), step S102 is skipped.

Here, the performance information storage processing will be described with reference to FIG. When the performance information storage process is executed, the power information acquisition unit 111 of the control device 100 acquires power information (step S111).

Specifically, the power information acquisition unit 111 of the control device 100 communicates with the distribution board 300 via the communication unit 120 and receives the measurement data of the power measurement device 312 of the distribution board 300 . As a result, the power information acquiring unit 111 of the control device 100 acquires power consumption information within the consumer. The power consumption to be acquired may be the instantaneous value at 0:00 of every hour, or the average value obtained by averaging the instantaneous values of the power consumption from the 1st to the 0:00 of every hour on an hourly basis. good.

Next, the weather information acquisition unit 112 of the control device 100 acquires weather information (step S112). Specifically, weather information acquisition unit 112 of control device 100 communicates with server device 900 via communication unit 120 to receive weather information distributed by server device 900 . Thereby, the weather information acquisition unit 112 of the control device 100 acquires the weather information. The weather information is, for example, the weather, temperature, and humidity in the region to which the consumer belongs at the time of acquisition.

The control unit 110 of the control device 100 associates the acquired power information with the weather information and stores them in the storage unit 140 as performance information (step S113). In this example, the power information and the weather information are associated based on the date and time when the power information is acquired and the date and time information included in the weather information. Note that the control unit 110 of the control device 100 uses the current date and time kept by the clock unit 130 at the time of acquiring the power information as the acquired date and time.

Next, as shown in FIG. 8, the control unit 110 of the control device 100 determines whether or not the current date and time kept by the clock unit 130 is the second processing time (step S103). The second processing time is the time at which the surplus power prediction process is executed, for example, 0:00 and 30:00 every hour. Note that the determination processing in steps S101 and S103 may be performed in parallel.

When the control unit 110 of the control device 100 determines that it is the second processing time (step S103; Yes), the control unit 110 of the control device 100 executes surplus power prediction processing (step S104). If the control unit 110 of the control device 100 determines that it is not the second processing time (step S103; No), the control process returns to step S101.

Here, the surplus power prediction processing will be described with reference to FIG. 10 . When the surplus power prediction process is executed, the weather information acquisition unit 112 of the control device 100 acquires weather forecast information (step S121). Specifically, weather information acquisition unit 112 of control device 100 communicates with server device 900 via communication unit 120 to receive weather forecast information distributed by server device 900 . Thereby, the weather information acquisition unit 112 of the control device 100 acquires the weather forecast information. The weather forecast information is, for example, the weather, temperature, and humidity in the area to which the customer belongs predicted in the future from the time of acquisition.

The control unit 110 of the control device 100 refers to the performance information stored in the storage unit 140 (step S122). The consumption pattern prediction unit 113 of the control device 100 predicts future power consumption patterns of consumers based on the weather forecast information obtained in step S121 and the performance information referred to in step S122 (step S123).

The power generation amount prediction acquisition unit 114 acquires, from the server device 900, the prediction information of the power generation amount of the power generation equipment 200 in the time zone of the consumption pattern predicted by the consumption pattern prediction unit 113 (step S124). The surplus power prediction unit 115 predicts surplus power and a time zone in which surplus power is generated by taking a difference between the consumption pattern predicted in step S123 and the amount of power generation predicted in step S124 (step S125). This completes the surplus power prediction process.

Next, as shown in FIG. 8, the control unit 110 of the control device 100 determines whether or not the current date and time kept by the clock unit 130 is the notification timing (step S105). The notification timing is the timing for controlling the notification device 400 . For example, the time is a predetermined time before the scheduled time when the surplus power is generated, and the time is a predetermined time before the scheduled time when the surplus power is lost. The predetermined time is set in consideration of the time during which the user who receives the notification acts to increase or decrease the amount of power used. The predetermined time is, for example, 30 minutes.

When the control unit 110 of the control device 100 determines that it is not the notification timing (step S105; No), the control process returns to step S101. On the other hand, when the control unit 110 of the control device 100 determines that it is the notification timing (step S105; Yes), the control execution unit 116 of the control device 100 generates a control signal (step S106).

The control signal is generated based on the control information stored in storage section 140 . When referring to the control information, only the information of the row in which the notification effective column is "effective" may be read. The control signal includes information indicating the time period in which the surplus power predicted in the surplus power prediction process will occur and the magnitude of the surplus power. Note that the control device 100 does not include an effective notification column in the storage unit 140, or ignores the value set in the effective notification column depending on the user's setting, and controls all the notification devices 400. good.

The control execution unit 116 of the control device 100 transmits the generated control signal to the notification device 400 via the communication unit 120 (step S107). In transmitting the control signal, the identification number included in the control information is the destination. After that, the control process returns to step S101, and the processes from step S101 to step S107 described above are repeatedly executed.

So far, the control processing of the control device 100 has been described. Therefore, the notification operation of the notification device 400 that receives the control signal from the control device 100 will be described in detail below.

FIG. 11 shows an example of the power consumption indicated by the future power consumption pattern acquired by the control device 100 and the generated power indicated by the prediction information of the future power generation amount of the power generation equipment 200 . In this example, it is predicted that the generated power will exceed the consumed power at 10:00 and surplus power will be generated, and that the generated power will fall below the consumed power at 14:00 and the surplus power will disappear. Therefore, the notification timings of step S105 are 9:30 and 13:30, which are 30 minutes earlier.

In this case, when the current date and time kept by the time keeping unit 130 reaches 9:30, the control device 100 controls the control information shown in FIG. 400 to the television and the mobile phone.

FIG. 12 shows an example of the notification message displayed on the display screen of the mobile phone, which is the notification device 400 that received the control signal. The mobile phone receives the control signal as short mail at 9:30, 30 minutes before the surplus power occurs. This notification message is displayed when the user operates the mobile phone to display the received short mail on the mobile phone. The text of the short mail is, for example, "Surplus power generation is expected. January 9 (Monday) 10:00 to 14:00".

FIG. 13 shows an example of the notification message displayed on the display screen of the television, which is the notification device 400 that received the control signal. This example shows a notification message displayed in characters when the control signal is received at 9:30, 30 minutes before the occurrence of surplus power. The notification message is, for example, "Notice: surplus power generation will occur between 10:00 and 14:00."

FIG. 14 shows an example of the notification message displayed on the display screen of the television, which is the notification device 400 that received the control signal. This example shows the notification message displayed in characters when the control signal is received at 13:30, which is 30 minutes before the surplus power disappears. The notification message is, for example, "Notice: The amount of power generation will fall below the amount of consumption in 30 minutes."

By viewing such a notification message, the user can know the time period when surplus power is generated. Note that the notification message may indicate the magnitude of the surplus power expected to be generated, or may exemplify the electric devices 500 that can be used within the surplus power range.

As described above, the power management system 1 according to this embodiment can also be applied to an environment without a power storage device. In addition, since the notification device 400 notifies the generation time of the surplus power, it is possible to encourage the user to use the power and effectively utilize the surplus power. Since the surplus power is used in real time, wasteful loss is reduced compared to the case where the surplus power is stored in the power storage device and used, and the surplus power is used more efficiently. In addition, the user can use electric power by selecting a desired electric device 500 rather than a preset device. Therefore, it is possible to improve the convenience and the efficiency of using surplus power.

(Modification 1)
The power management system 2 according to Modification 1 will be described below. In Modification 1 and Modifications 2 to 5, which will be described later, constituent elements common to those described in the above embodiments are denoted by the same reference numerals.

As shown in FIG. 15 , power management system 2 is different from power management system 1 according to the embodiment in that power storage device 600 and commercial system power supply 700 are connected.

A control device 101 included in the power management system 2 communicates with the power storage device 600 . Power storage device 600 and system power supply 700 are connected to distribution board 300 . Electricity storage device 600 is charged from distribution board 300 and discharged from electricity storage device 600 to distribution board 300 . System power supply 700 supplies power to distribution board 300 and receives reverse power flow from distribution board 300 .

Here, the configuration of the control device 101 will be described with reference to FIG. 16 . In the control device 101 , the control unit 150 includes an output control instruction acquisition unit 157 and a device information acquisition unit 158 .

The output control instruction acquisition unit 157 acquires an output control instruction signal indicating an instruction to prohibit reverse power flow when the power reversely flowed to the system power supply 700 by the power generation of the power generation equipment 200 is expected to exceed the demand. do. Output control instruction acquisition unit 157 acquires the output control instruction signal by receiving the output control instruction signal from server device 900 via communication unit 120 .

The device information acquisition unit 158 acquires device information such as the current storage amount of the power storage device 600, the rated storage capacity, and the charging and discharging schedule. The consumption pattern prediction unit 113 predicts consumption patterns based on the device information acquired by the device information acquisition unit 158 . For example, the power charged to power storage device 600 is added to the power consumption, and the power discharged from power storage device 600 is subtracted from the power consumption.

As a result, the influence of the presence of power storage device 600 is reflected in the consumption pattern predicted by consumption pattern prediction unit 113 . It should be noted that the charging power and discharging power of power storage device 600 may be used for addition and subtraction of the power generation amount instead of addition and subtraction of power consumption. That is, the influence of the presence of power storage device 600 should be reflected in the prediction of surplus power.

In addition, since the power management system 2 is connected to the system power supply 700, if the power generated by the power generation equipment 200 can be reversely flowed to the system power supply 700, priority is given to the reverse power flow, and the output control instruction acquisition unit 157 controls the output. Control to report the generation of surplus power may be performed only when an instruction is acquired. This enables economical operation of the power generation facility 200 .

(Modification 2)
The power management system 3 according to Modification 2 will be described below. The configuration of the power management system 3 is basically the same as that of the power management system 1 . However, as shown in FIG. 17 , power management system 3 differs from power management system 1 according to the embodiment in that control device 102 can communicate with electrical equipment 500 .

FIG. 18 is an example of control information stored in the storage unit 140 of the control device 102 of the power management system 3. As shown in FIG. This control information differs from the control information described in the embodiment in that automatic control and control detail columns are added, and that the control target includes not only the notification device 400 but also the electric device 500 .

In this example, an air conditioner is registered as the electrical device 500 to be controlled. For the air conditioner, the automatic control is registered as "enabled" and the control details as "surplus>400 W: power ON". Further, for the television, which is the notification device 400, automatic control is registered as "valid" and control details are registered as "surplus≦0: power OFF".

The mobile phone and the PC, which are the notification device 400, are blank because the automatic control is not "enabled". Since the air conditioner is not the notification device 400, the notification method and notification effectiveness are blank.

Controlled objects for which automatic control is "enabled" are controlled to actively use during the time period when the generation of surplus power is predicted, and during the time period when the generation of surplus power is not predicted, Controlled to limit use. In step S106 in the flowchart illustrated in FIG. 8, the control execution unit 116 extracts the control target for which both the effective notification column and the automatic control column indicate "effective". The control execution unit 116 refers to the surplus power condition and device operation described in the control details column from the extracted controlled object. When the surplus power meets the surplus power condition referred to, control execution unit 116 adds the information indicating the time period in which surplus power predicted in the surplus power prediction process occurs and the magnitude of surplus power to the referenced device operation. to generate a control signal containing

In the example of FIG. 18, the television, which is the notification device 400, is controlled to be turned off during a time period in which the generation of surplus power is not expected. Also, the air conditioner, which is the electric device 500, is controlled to be turned on when the surplus power is expected to exceed 400W. When the power supply of the air conditioner is turned on, the notification device 400 displays the amount of surplus power, or indicates the electric devices 500 that can be used within the range of surplus power. Notification is made after deducting the electric power.

Note that such control is not limited to the example of FIG. 18 . For example, the controlled variables such as the set temperature and set humidity of the air conditioner may be changed according to the presence or absence of predicted generation of surplus power. Also, the ON/OFF state of power sources such as air conditioners and televisions may be changed according to the presence or absence of predicted surplus power generation. Electric device 500 having a rechargeable battery may be charged during a time period in which surplus power is expected to be generated.

According to the configuration of the power management system 3 according to Modification 2, the surplus power can be actively utilized by automatic control. It should be noted that this does not prevent the user from selecting the desired electrical device 500 and using the surplus power.

(Modification 3)
In the embodiment, control device 100 generates the control signal based on the consumption pattern predicted by consumption pattern prediction section 113 . However, actual power consumption may differ from predicted consumption patterns.

Therefore, the control device 103 according to the modification 3 that performs control for causing the notification device 400 to perform notification in such a case will be described below. In the following description, the difference between the power consumption indicated by the predicted consumption pattern and the actual power consumption is referred to as "non-pattern power consumption".

In the control device 103 according to Modification 3, the control unit 160 includes an out-of-pattern power consumption acquisition unit 169 as shown in FIG. 19 . The out-of-pattern power consumption acquisition unit 169 acquires out-of-pattern power consumption by calculating the difference between the power consumption pattern predicted by the consumption pattern prediction unit 113 and the actual power consumption acquired by the power information acquisition unit 111 . .

The control execution unit 166 performs control based on the non-pattern power consumption in addition to the control of the control execution unit 116 described in the embodiment. When the non-pattern power consumption acquired by the non-pattern power consumption acquiring unit 169 is equal to or greater than a predetermined reference value, the control execution unit 166 indicates that the non-pattern power consumption may exceed the surplus power. Generate a control signal for notification. This control signal is transmitted to the notification device 400 via the communication unit 120 . Note that the reference value is a value set to prevent the surplus power from becoming insufficient due to unexpected circumstances.

Here, control processing executed by the control device 103 will be described with reference to FIG. 20 . This control process differs from the control process described in the embodiment in that the predicted consumption pattern is stored in the storage unit 140 in the surplus power prediction process of step S134. Further, the control process differs from the control process described in the embodiment in that it includes a process (step S137) for activating a subroutine after transmitting the control signal in step S107. Other processing is the same as the control processing described in the embodiment.

The specific contents of the subroutine will be described below with reference to FIG. Note that the subroutine is periodically executed after being activated in step S137.

First, when the subroutine is executed, the power information acquisition unit 111 of the control device 103 acquires power information indicating the power consumption in the nearest consumer from the power measurement device 312 of the distribution board 300 via the communication unit 120. (step S141). This power consumption indicates the actual power consumption.

Next, the non-pattern power consumption acquisition unit 169 of the control device 103 acquires non-pattern power consumption (step S142). Specifically, the non-pattern power consumption acquiring unit 169 of the control device 103 acquires the power consumption indicated by the consumption pattern stored in the storage unit 140 in the surplus power prediction process in step S134 and the power information obtained in step S141. Out-of-pattern power consumption is obtained by calculating the difference in power consumption.

Here, the control execution unit 166 determines whether or not the out-of-pattern power consumption acquired by the out-of-pattern power consumption acquisition unit 169 is equal to or greater than a predetermined reference value (step S143). If the non-pattern power consumption is less than the reference value (step S143; No), the subroutine returns to step S141. If the non-pattern power consumption is greater than or equal to the reference value (step S143; Yes), the control execution unit 166 generates a control signal (step S144). The control execution unit 166 transmits the generated control signal to the notification device 400 (step S145).

The notification device 400 that has received the control signal executes the notification operation. This notification operation is the same as the notification operation described in the embodiment except for the content of the notification message. The content of this notification message indicates that the situation is different from the notification message executed by the notification device 400 by transmitting the control signal in step S107. For example, "Power consumption is likely to exceed power generation. Please turn off unnecessary electrical devices."

In this case, the user is notified that the situation is different from that of the previous notification message, so it is possible to prompt the user to reconsider. Note that the notification message may notify the amount of surplus power at that point in time, if necessary. Also, as described in the embodiment, the notification message may be output by voice instead of display.

(Modification 4)
In the above example, the control devices 100 , 101 , 102 and 103 are configured to acquire weather information from the server device 900 . However, the weather conditions indicated by the weather information acquired from the server device 900 may not match the actual weather conditions at the consumer.

Therefore, in the control devices 101, 102, and 103, the weather information acquisition unit 112 receives measurement data from various sensors such as a temperature sensor, a humidity sensor, and an illuminance sensor installed at the customer via the communication unit 120. good too. In this case, the measurement data received from various sensors is the weather information. In addition, the weather information acquisition unit 112 may receive measurement data indicating weather information from various sensors, receive weather information from the server device 900, and acquire any of them as weather information. The weather information may be calculated and acquired by adding weights to them. As a result, it is possible to improve the prediction accuracy of the consumption pattern and the prediction accuracy of the surplus power.

Further, as shown in FIG. 22, information on the power generated by the power generation equipment 200 may be added to the performance information. In this case, in step S124 of the surplus power prediction process of FIG. 10, the information acquired from the server device 900 may not be used as the prediction information of the power generation amount. For example, the power generation amount prediction acquisition unit 114 of the control devices 100, 101, 102, and 103 stores in the storage unit 140 the past power generation amount performance data associated with the weather information closest to the weather conditions indicated by the weather forecast information. It is possible to obtain the prediction information of the amount of power generation based on the actual data of the amount of power generation obtained from the actual data of the amount of power generation.

(Modification 5)
The control device 100 according to the embodiment may have a learning function in order to improve the accuracy of prediction information. Therefore, the control device 104 according to Modification 5 will be described below.

Control device 104 differs from control device 100 according to the embodiment in that control unit 170 includes prediction correction unit 177, as shown in FIG. The prediction correcting unit 177 calculates the difference between the data indicated by the prediction information and the data indicated by the performance information in the time zone of the prediction information using an arbitrary algorithm and neural network. 114, feeds back to the surplus power prediction unit 115 to correct the prediction information of the consumption pattern, power generation amount, and surplus power. Note that the prediction correction unit 177 may accumulate the difference between the data indicated by the prediction information and the data indicated by the performance information at the time of the prediction information in the storage unit 140, and correct the accumulated data by a statistical method. good. Such correction can improve the accuracy of the prediction information.

Hardware of the control device 100 according to the embodiment is configured by a processor 1001, a memory 1002, and an interface 1003, as shown in FIG. 24, for example. Each function of control device 100 is implemented by processor 1001 executing a program stored in memory 1002 . The interface 1003 is for connecting the control device 100, the power generation equipment 200, the distribution board 300, the notification device 400 and the server device 900 to establish communication.

Note that the interface 1003 may be composed of a plurality of interfaces as required. Also, the processor 1001 and the memory 1002 may be composed of multiple processors and multiple memories, which may work together to perform the functions described above. Control devices 101, 102, 103, and 104 in Modifications 1 to 5 can be configured similarly to control device 100 according to the embodiment.

It should be noted that the present invention is not limited to the above-described embodiment and modified examples 1 to 5, and various modifications and applications are possible without departing from the scope of the present invention. The constituent elements of the above-described embodiment and modified examples 1 to 5 can be combined as long as there is no technical contradiction. Further modifications will be described below.

(Modification)
Each function of the controllers 100, 101, 102, 103, 104 can also be implemented by a normal computer. Specifically, in the above embodiments, the programs executed by the control devices 100 , 101 , 102 , 103 and 104 are pre-stored in the ROM of the storage unit 140 . However, the program may be stored and distributed on computer-readable recording media such as flexible discs, CD-ROMs (Compact Disc Read Only Memory), DVDs (Digital Versatile Discs) and MOs (Magneto-Optical Discs), etc. can be read into the computer and installed to configure a computer capable of realizing each of the functions described above. When each function is shared between an OS (Operating System) and an application, or when the OS and an application cooperate with each other, only portions other than the OS may be stored in the recording medium.

Furthermore, it is also possible to superimpose each program on a carrier wave and distribute it via a communication network. For example, the program may be posted on a bulletin board (BBS, Bulletin Board System) on a communication network and distributed via the network. Then, these programs may be activated and executed in the same manner as other application programs under the control of the OS, thereby executing the above processing.

Some of the components of control devices 100, 101, 102, 103, and 104 may be provided in external devices connected via a communication network. For example, the configuration may be such that information required for control is acquired from another control device, storage device, cloud server, or the like, which is an external device.
