Description

The present invention relates to control devices, power management systems, control methods and programs.

In recent years, power generation facilities using natural energy such as solar power and wind power have become widespread. Such power generation equipment has been introduced as a distributed power source to small-scale consumers including ordinary households.

Power generation facilities that use natural energy vary in the amount of power generated depending on the weather conditions. When the generated power exceeds the power consumption of the consumer, it becomes surplus power. In order to utilize such surplus power, a system in which the surplus power is reversely flowed to a commercial grid power source and sold is also widespread.

However, an imbalance between supply and demand due to reverse power flow may cause voltage fluctuations of commercial grid power supplies, power outages, and the like. Therefore, a system that controls to limit the reverse power flow to the grid power supply under certain conditions, a system that stores excess power that cannot be reverse power flow into the power storage device, and the like are known.

However, more surplus power cannot be utilized during the period in which the reverse power flow to the grid power supply is restricted or the storage amount of the power storage device reaches the rated capacity value. Various proposals have been made to utilize such surplus electricity.

For example, Patent Document 1 discloses a power control system that automatically controls an electric device and consumes the surplus power when a surplus is generated in the power generated by using natural energy. Patent Document 2 discloses a system that displays a message prompting power consumption when the predicted surplus power amount exceeds the free capacity of the storage battery. Patent Document 3 discloses a system that notifies a consumer of a time zone in which reverse power flow to a grid power source is restricted and encourages the consumer to consume power during the time limit.

In the system disclosed in Patent Document 1, the electric device automatically controlled to consume the surplus electric power may not be the device that the user actually wants to use. Therefore, convenience is reduced.

The system disclosed in Patent Document 2 is configured to promote 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. Surplus power can be stored in an environment with a storage battery, but in an environment without a storage battery, the surplus power cannot be stored, so the need to use the surplus power in real time becomes higher. In addition, using the surplus power in real time reduces wasteful loss and increases the efficiency of using the surplus power, rather than storing the surplus power in the 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 whether or not the surplus power is generated in that time zone is not considered. Therefore, there is a problem that self-consumption is promoted even when surplus electricity is not actually generated. There is also a problem that it cannot be applied to an environment that is not connected to a grid power supply.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a control device, a power management system, a control method, and a program having high convenience and utilization efficiency of surplus power.

In order to achieve the above object, the control device according to the present invention includes a power information acquisition unit, a weather information acquisition unit, a storage unit, a consumption pattern prediction unit, a power generation amount prediction acquisition unit, a surplus power prediction unit, and the like. It is equipped with a control execution unit. The power information acquisition unit acquires power information indicating the power consumption in the consumer from the current measuring device. The meteorological information acquisition unit acquires past or present meteorological information and meteorological forecast information. The storage unit stores the electric power information acquired by the electric power information acquisition unit and the past or present meteorological information acquired by the meteorological information acquisition unit in association with each other. The consumption pattern prediction unit predicts the future power consumption pattern in the consumer based on the power information and the weather information stored in the storage unit and the weather forecast information acquired by the weather information acquisition unit. The power generation amount forecast acquisition unit acquires the forecast information of the future power generation of the power generation facility in the consumer. The surplus power prediction unit predicts the surplus power generated in the future based on the consumption pattern predicted by the consumption pattern prediction unit and the power generation power prediction information acquired by the power generation amount prediction acquisition unit. The control execution unit controls the notification device to notify the time zone in which the surplus power is generated and the magnitude of the surplus power predicted by the surplus power prediction unit. The storage unit further stores identification information that can identify the notification device, notification effective information indicating whether or not the notification device notifies, and a notification method indicating how the notification device notifies. When the notification valid information is valid, the control execution unit controls the notification device according to the notification method at a time predetermined time before the scheduled time when the surplus power predicted by the surplus power prediction unit disappears. ..

Since the present invention performs control that does not depend on the free capacity of the power storage device, it can be applied to an environment without a power storage device. In addition, since the notification device notifies the time when the surplus power is generated, 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 as compared with the case where the power is stored in the power storage device and used, and the efficiency of using the surplus power can be improved. Further, since the user is not configured to use electric power for a preset device, he / she can select an electric device desired by himself / herself and use electric power.

Therefore, according to the present invention, the convenience and the utilization efficiency of the surplus electric power of the power generation facility can be improved.

The communication unit 420 includes a communication interface that can be connected to a wired or wireless LAN (Local Area Network), a communication interface that conforms to the Bluetooth® standard, and the like. The notification unit 430 includes a display, a speaker, and the like.

The electric device 500 is a device used in a consumer and consumes electric power generated by a power generation facility 200 and supplied via a distribution board 300.

The server device 900 is a device that distributes current or past weather information, weather forecast information, power generation amount prediction information, and the like, and is installed outside the consumer. The server device 900 may be a plurality of server devices that are different for each information to be distributed.

As shown in FIG. 5, the control device 100 includes a control unit 110 that controls the operation of the control device 100, a communication unit 120 that communicates with other devices, a timekeeping unit 130 that measures the current date and time, and various data. A storage unit 140 for storing the data is provided.

The control unit 110 performs various information processing using the received data of the communication unit 120, various data stored in the storage unit 140, and the like. The control unit 110 includes, for example, a CPU, a crystal oscillator that generates a reference clock signal, and the like.

The timekeeping unit 130 may acquire date and time information from the server device 900 and use it as reference information to calculate the current date and time based on the number of clocks and the reference information of the clock signal generated by the control unit 110. good. In this case, since the reference date and time information is acquired from the server device 900, there is an advantage that it is not necessary to set the date and time information in the initial setting.

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

Hereinafter, the functional configuration of the control unit 110 will be described.

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

In the following description, "acquisition" refers to the case of directly acquiring information by receiving it from an external device and the case of indirectly acquiring information by the own device performing arithmetic processing based on the received signal from the external device. It shall include the case of acquiring the information. The “prediction” includes a case where the prediction information is acquired by receiving the prediction information from the external device and a case where the own device makes a prediction by performing arithmetic processing.

The electric power information acquisition unit 111 acquires electric power information indicating the power consumption in the consumer. Specifically, the power information acquisition unit 111 acquires power information by receiving the measurement data of the power measurement device 312 of the distribution board 300 via the communication unit 120. Further, the power information acquisition unit 111 acquires the generated power by receiving the 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, the weather information acquisition unit 112 acquires the weather information by receiving the weather information from the server device 900 via the communication unit 120. The weather information acquisition unit 112 acquires weather forecast information by the same method.

The weather information includes date and time information indicating the time zone and weather conditions in that time zone, for example, the weather is fine in the time zone from 16:00 to 18:00 on January 3, and the temperature is 23 ° C. Is done. The weather forecast information includes date and time information indicating a future time zone and weather conditions predicted for that time zone.

The power information and the past or present weather information acquired by the weather information acquisition unit 112 are associated with the power information acquired by the power information acquisition unit 111 in a time zone close to the date and time information included in the weather information, and the actual information. Is stored in the storage unit 140.

The consumption pattern prediction unit 113 is 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, and the power in the consumer in the future predetermined period. Predict the consumption pattern of. Specifically, the consumption pattern prediction unit 113 searches the storage unit 140 for weather information having a weather condition close to the weather condition indicated by the weather forecast information, and determines the power consumption indicated by the power information associated with the weather condition in the future. Predict as the power consumption of.

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

The method for predicting the consumption pattern is not limited to a specific method, and any method can be used. For example, various parameters may be weighted to predict the consumption pattern. As various parameters, date and time information and weather information included in the actual information, types of the 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 from 4:00 to 6:00 and the weather information is snow, it means that the environment is cold and the user is sleeping. Therefore, in the notification device 400 and the electric device 500, the power consumption can be predicted by weighting the ratio of the air conditioner, the ratio of the equipment not used by the user while sleeping, and the like. Further, the prediction may be made by using machine learning that feeds back the result of comparing the prediction and the actual result.

The power generation amount prediction acquisition unit 114 acquires the prediction information of the power generation power generated by the power generation facility 200 in the consumer 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 area to which the consumer belongs, the specifications of the power generation facility 200, and the installation conditions are stored in advance in the storage unit 140. 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 the prediction information in response to this request. As a result, the power generation amount prediction acquisition unit 114 acquires the power generation amount prediction information.

The surplus power prediction unit 115 determines the timing at which surplus power is generated and the surplus power based on the power consumption pattern predicted by the consumption pattern prediction unit 113 and the power generation power prediction information acquired by the power generation amount prediction acquisition unit 114. Predict the size. Specifically, the surplus power prediction unit 115 sets the value obtained by subtracting the power consumption indicated by the power consumption pattern from the generated power indicated by the prediction information as the magnitude of the surplus power.

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

Hereinafter, the actual result information and the control information stored in the above-mentioned storage unit 140 will be described.

As shown in FIG. 6, the actual 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 consumer at the date and time indicated by the date and time information. Includes. The actual information is shown in chronological order based on the hourly date and time information.

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

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

When the notification enable is set to "valid", the notification operation is executed according to the notification method. Even when a plurality of notification devices 400 of the same type are registered, in order to make it possible to identify those notification devices 400, a column of identification names is further added to the control information, and the user can arbitrarily add an identification name column to each notification device 400. An distinguished name may be set.

In the example of FIG. 7, a television, a mobile phone, and a PC (personal computer) are included as device types. The identification number of the television is the IP address, the notification method is character display, and the notification is enabled.

In this case, the control information is transmitted to the IP address, and the television notifies by displaying characters. For mobile phones, the identification number is a telephone number, the notification method is short mail, and notification is enabled. In this case, the control information is transmitted to the mobile phone as a short mail, and the mobile phone notifies by the short mail. In the PC, the identification number is an e-mail address, the notification method is e-mail, and the notification is disabled. In this case, the control information is not transmitted to the PC and the notification is not executed.

The device that can be used as the notification device 400 is not limited to a television, a mobile phone, and a PC. The notification device 400 may be any device capable of transmitting 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 device 400 may be notified by voice. If the notification device 400 is a remote control device provided with a two-way communication function and a display screen, 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 the notification method. However, strictly speaking, the notification method is information necessary for generating a signal for operating each notification function. For example, in the transmission of e-mail, it is the information of the mail header such as the character encoding, the sender's mail address, and the mail subject, and in the notification by the character display of the television, it is the character display command of the common protocol of ECHONET. Although the specific contents of these are not shown in FIG. 7, they are actually information included in the notification method.

Up to this point, the configuration of each device included in the power management system 1 has been described. Hereinafter, the control process executed by the control device 100 will be described with reference to FIGS. 8 to 10. It should be noted 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 measured by the time measuring unit 130 is the first processing time (step S101). The first processing time is a time for storing the actual information in the storage unit 140, for example, zero minutes per hour.

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 the actual information storage process (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 actual information storage process will be described with reference to FIG. 9. When the actual information storage process is executed, the power information acquisition unit 111 of the control device 100 acquires the 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 acquisition unit 111 of the control device 100 acquires information on the power consumption in the consumer. The power consumption to be acquired may be an instantaneous value at zero minutes per hour, or may be an average value obtained by averaging the instantaneous values of power consumption between 1 minute per hour and the next zero minute in 1-hour units. good.

Next, the weather information acquisition unit 112 of the control device 100 acquires the weather information (step S112). Specifically, the weather information acquisition unit 112 of the control device 100 communicates with the server device 900 via the communication unit 120, and receives the weather information distributed by the server device 900. As a result, the weather information acquisition unit 112 of the control device 100 acquires the weather information. Meteorological information is, for example, the weather, temperature, and humidity in the area 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 it in the storage unit 140 as actual information (step S113). In this example, the electric power information and the meteorological information are associated with each other based on the acquisition date and time of the electric power information and the date and time indicated by the date and time information included in the meteorological information. The control unit 110 of the control device 100 uses the current date and time measured by the timekeeping unit 130 at the time of acquisition of the power information as the acquisition 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 measured by the timekeeping unit 130 is the second processing time (step S103). The second processing time is a time when the surplus power prediction processing is executed, and is, for example, zero minutes per hour and 30 minutes per hour. The discrimination process of step S101 and step 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 the surplus power prediction process (step S104). When the control unit 110 of the control device 100 determines that it is not the second processing time (step S103; No), the control processing returns to step S101.

Here, the surplus power prediction process will be described with reference to FIG. When the surplus power prediction process is executed, the weather information acquisition unit 112 of the control device 100 acquires the weather forecast information (step S121). Specifically, the weather information acquisition unit 112 of the control device 100 communicates with the server device 900 via the communication unit 120, and receives the weather forecast information distributed by the server device 900. As a result, 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 consumer predicted in the future from the time of acquisition belongs.

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

The power generation amount prediction acquisition unit 114 acquires the prediction information of the power generation amount of the power generation facility 200 in the time zone of the consumption pattern predicted by the consumption pattern prediction unit 113 from the server device 900 (step S124). The surplus power prediction unit 115 predicts the surplus power and the time zone in which the surplus power is generated by taking the difference between the consumption pattern predicted in step S123 and the power generation amount predicted in step S124 (step S125). This ends 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 measured by the timekeeping unit 130 is the notification timing (step S105). The notification timing is a 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 when the user who receives the notification acts to increase or decrease the power consumption. The predetermined time is, for example, 30 minutes.

When the control unit 110 of the control device 100 determines that the notification timing is not reached (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 the notification timing is reached (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 the storage unit 140. When referring to the control information, only the information in the row in which the notification valid column is "valid" may be read out. The control signal includes information indicating the time zone in which the surplus power predicted in the surplus power prediction process is generated and the magnitude of the surplus power. Even if the control device 100 does not have the notification valid column in the storage unit 140, or ignores the value set in the notification valid 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 the transmission of 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 process of step S107 is repeatedly executed from step S101 described above.

Up to this point, the control process of the control device 100 has been described. Therefore, the notification operation of the notification device 400 that has received 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 facility 200. In this example, it is predicted that the generated power exceeds the power consumption at 10:00 to generate surplus power, and the generated power falls below the power consumption at 14:00 and the surplus power disappears. Therefore, the notification timings of step S105 are 9:30 and 13:30, which are 30 minutes before them.

In this case, the control device 100 is a notification device in which the notification valid is "valid" in the control information shown in FIG. 7 when the time of the current date and time measured by the timing unit 130 reaches 9:30. The control signal is transmitted to the television and the mobile phone which are 400.

FIG. 12 shows an example of a notification message displayed on the display screen of a mobile phone which is a notification device 400 that has received a control signal. The mobile phone receives the control signal as a short mail at 9:30, which is 30 minutes before the surplus power is generated. 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, "A surplus of generated power is expected. 1/9 (Monday) 10:00 to 14:00".

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

FIG. 14 shows an example of a notification message displayed on the display screen of the television of the notification device 400 that has received the control signal. This example shows a notification message displayed in characters when a 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 be less than the amount of consumption after 30 minutes."

By seeing such a notification message, the user can know the time zone in which the surplus power is generated. The notification message may indicate the magnitude of the surplus power that is expected to be generated, or may exemplify the electric device 500 that can be used within the range of the surplus power.

As described above, the power management system 1 according to this embodiment can be applied to an environment without a power storage device. Further, by notifying the time when the surplus power is generated by the notification device 400, 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 and the utilization efficiency of the surplus power is high as compared with the case where the power is stored in the power storage device and used. Further, the user can select the electric device 500 desired by himself / herself and use the electric power instead of the preset device. Therefore, the convenience and the utilization efficiency of the surplus electric power can be improved.

(Modification 1)
Hereinafter, the power management system 2 according to the modification 1 will be described. In the modified example 1 and the modified examples 2 to 5 described later, the same reference numerals are given to the constituent elements common to the constituent elements described in the above embodiment.

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

The control device 101 included in the power management system 2 communicates with the power storage device 600. The power storage device 600 and the system power supply 700 are connected to the distribution board 300. The distribution board 300 charges the power storage device 600, and the power storage device 600 discharges the power storage device 300 to the distribution board 300. The grid power supply 700 supplies power to the distribution board 300 and receives reverse power flow from the distribution board 300.

Here, the configuration of the control device 101 will be described with reference to FIG. 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 it is expected that the power reverse power flowed to the grid power source 700 due to the power generation of the power generation facility 200 exceeds the demand. do. The output control instruction acquisition unit 157 acquires an output control instruction signal by receiving an output control instruction signal from the server device 900 via the 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 the consumption pattern based on the device information acquired by the device information acquisition unit 158. For example, the charging power to the power storage device 600 is added to the power consumption, and the discharge power from the power storage device 600 is subtracted from the power consumption.

As a result, the influence of the presence of the power storage device 600 is reflected in the consumption pattern predicted by the consumption pattern prediction unit 113. The charging power and the discharging power of the power storage device 600 may be used for adding or subtracting the amount of power generation instead of adding or subtracting the power consumption. That is, the influence of the presence of the power storage device 600 may be reflected in the prediction of the surplus power.

Further, since the power management system 2 is connected to the grid power supply 700, if the power generated by the power generation facility 200 can be reverse power flowed to the grid power supply 700, the reverse power flow is prioritized and the output control instruction acquisition unit 157 controls the output. The control to notify the generation of surplus power may be executed only when the instruction is acquired. This enables economical operation of the power generation facility 200.

(Modification 2)
Hereinafter, the power management system 3 according to the modification 2 will be described. 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, the power management system 3 differs from the power management system 1 according to the embodiment in that the control device 102 can communicate with the electric device 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. This control information is different from the control information described in the embodiment in that the columns of automatic control and control details are added, and the control target includes not only the notification device 400 but also the electric device 500.

In this example, the air conditioner is registered as the electric device 500 to be controlled. For the air conditioner, the automatic control is registered as "effective" and the control details are registered as "surplus> 400W: power ON". Further, in the television which is the notification device 400, the automatic control is registered as "effective" and the control details are registered as "surplus ≤ 0: power off".

The mobile phone and the PC, which are the notification devices 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.

The control target for which automatic control is "enabled" is controlled to be actively used in the time zone when the generation of surplus power is predicted, and in the time zone when the generation of surplus power is not predicted. Controlled to limit usage. The control execution unit 116 extracts a control target in which both the notification valid column and the automatic control column are “valid” in step S106 in the flowchart described with reference to FIG. The control execution unit 116 refers to the surplus power condition and the device operation described in the control details column from the extracted control target. When the surplus power matches the referenced surplus power condition, the control execution unit 116 operates the referenced device in addition to the information indicating the time zone in which the surplus power is generated and the magnitude of the surplus power predicted in the surplus power prediction process. To generate a control signal containing.

In the example of FIG. 18, the television, which is the notification device 400, is controlled so that the power is turned off at a time when the generation of surplus power is not predicted. Further, the air conditioner, which is the electric device 500, is controlled so that the power is turned on when the surplus power is predicted to be larger than 400 W. When the power of the air conditioner is controlled to be turned on, the notification device 400 consumes by operating the air conditioner when displaying the magnitude of the surplus power or when exemplifying the electric device 500 that can be used within the range of the surplus power. Notify after deducting the power consumption.

It should be noted that such control is not limited to the example of FIG. For example, the control amounts such as the set temperature and the set humidity of the air conditioner may be changed according to the predicted generation of surplus power. Further, the ON / OFF state of the power of the air conditioner, the television, or the like may be changed according to the predicted generation of surplus power. The electric device 500 provided with the rechargeable battery may be charged during the time period when the generation of surplus power is predicted.

According to the configuration of the power management system 3 according to the modification 2, the surplus power can be positively utilized by automatic control. It does not prevent the user from selecting the desired electric device 500 and using the surplus power.

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

Therefore, the control device 103 according to the third modification, which controls the notification device 400 to execute the 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 "out-of-pattern power consumption".

As shown in FIG. 19, in the control device 103 according to the third modification, the control unit 160 includes an out-of-pattern power consumption acquisition unit 169. The out-of-pattern power consumption acquisition unit 169 acquires the 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 further performs control based on the power consumption outside the pattern in addition to the control of the control execution unit 116 described in the embodiment. The control execution unit 166 determines that the out-of-pattern power consumption may exceed the surplus power when the out-of-pattern power consumption acquired by the out-of-pattern power consumption acquisition unit 169 is equal to or higher than a predetermined reference value. Generates a control signal for notification. This control signal is transmitted to the notification device 400 via the communication unit 120. The reference value is a value set to prevent the surplus power from becoming insufficient due to unexpected circumstances.

Here, the control process executed by the control device 103 will be described with reference to FIG. 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 in step S134. Further, it differs from the control process described in the embodiment in that it includes a process of invoking a subroutine (step S137) after transmitting a control signal in step S107. The other processing is the same as the control processing described in the embodiment.

Hereinafter, the specific contents of the subroutine will be described with reference to FIG. The subroutine is periodically executed after being started 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 out-of-pattern power consumption acquisition unit 169 of the control device 103 acquires the out-of-pattern power consumption (step S142). Specifically, the non-pattern power consumption acquisition unit 169 of the control device 103 indicates 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 acquired in step S141. The out-of-pattern power consumption is acquired 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 higher than a predetermined reference value (step S143). If the out-of-pattern power consumption is less than the reference value (step S143; No), the subroutine returns to step S141. If the power consumption outside the pattern is equal to or higher than 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 due to the transmission of the control signal in step S107. For example, "The power consumption is likely to exceed the generated power. Please turn off the power of unnecessary electrical equipment."

In this case, since the user is notified that the situation is different from the previous notification message, it is possible to prompt the user to reconsider. The notification message may be used to notify the magnitude of the surplus power at that time, if necessary. Further, as described in the embodiment, the notification message may be a voice output instead of a display.

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

Therefore, in the control devices 101, 102, 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 in the consumer via the communication unit 120. May be good. In this case, the measurement data received from various sensors is the weather information. Further, the weather information acquisition unit 112 may receive measurement data indicating the weather information from various sensors, receive the weather information from the server device 900, and acquire any of them as the weather information. Meteorological information may be calculated and acquired by weighting them. This makes it 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 generated power of the power generation facility 200 may be added to the actual 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 power generation amount prediction information. For example, the power generation amount prediction acquisition unit 114 of the control devices 100, 101, 102, 103 stores the actual data of the past power generation amount associated with the weather information closest to the weather condition indicated by the weather forecast information in the storage unit 140. It is possible to acquire the forecast information of the amount of power generation based on the actual data of the amount of power generation by acquiring from the actual information.

(Modification 5)

As shown in FIG. 23, the control device 104 differs from the control device 100 according to the embodiment in that the control unit 170 includes the prediction correction unit 177. The prediction correction unit 177 uses an arbitrary algorithm and a neural network to obtain the difference between the data indicated by the prediction information and the data indicated by the actual information in the time zone of the prediction information in the consumption pattern prediction unit 113 and the power generation amount prediction acquisition unit. The data is fed back to 114 and the surplus power prediction unit 115 to correct the consumption pattern, the amount of power generation, and the prediction information of the surplus power. Even if the prediction correction unit 177 stores the difference between the data indicated by the prediction information and the data indicated by the actual information at the time of the prediction information in the storage unit 140 and corrects the accumulated data by a statistical method. good. With such a correction, the accuracy of the prediction information can be improved.

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

The interface 1003 may be configured by a plurality of interfaces as needed. Further, the processor 1001 and the memory 1002 may be composed of a plurality of processors and a plurality of memories, and they may cooperate with each other to execute the above functions. In the first to fifth modifications, the control devices 101, 102, 103, and 104 can be configured in the same manner as the control device 100 according to the embodiment.

However, the program is stored and distributed on a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disk Read Only Memory), a DVD (Digital Versaille Disc), and an MO (Magnet-Optical Disc), and the program is distributed. You may configure a computer capable of realizing each of the above-mentioned functions by loading and installing the above-mentioned in a computer. When each function is realized by the division of the OS (Operating System) and the application or the cooperation between the OS and the application, only the part other than the OS may be stored in the recording medium.

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