  FIG. 1 is a diagram showing a configuration of a power management system 1 according to an embodiment of the present invention. The power management system 1 is a so-called HEMS (Home Energy Management System) system that manages power used in a general home.

  As shown in FIG. 1, the power management system 1 includes a control device 2, an operation terminal 3, a power measuring device 4, and a plurality of electric devices 5 (electric devices 5-1, 5-2, ...). Prepare The control device 2 is installed in an appropriate place in the house H, monitors the power consumed in the house H, that is, the demand place, and displays the power consumption state via the operation terminal 3. Further, the control device 2 controls the operation of the electric device 5 in order to suppress the electric power consumed in the house H.

  The operation terminal 3 is a mobile device such as a smartphone or a tablet terminal, which includes an input device such as a push button, a touch panel, a touch pad, a display device such as an organic EL display or a liquid crystal display, and a communication interface. The operation terminal 3 communicates with the control device 2 according to a well-known communication standard such as Wi-Fi (registered trademark), Wi-SUN (registered trademark), or a wired LAN. The operation terminal 3 receives an operation from the user and transmits information indicating the received operation content to the control device 2. Further, the operation terminal 3 receives the information transmitted from the control device 2 for presenting to the user, and displays the received information. In this way, the operation terminal 3 plays a role as an interface (user interface) with the user.

  The electric power measurement device 4 measures the value of electric power in the electric power line D1 arranged between the commercial power supply 6 and the distribution board 7. The power measuring device 4 is connected to the CT (Current Transformer) 1 connected to the power line D1 via a communication line. CT1 is a sensor that measures an alternating current. The power measuring device 4 measures the power value on the power line D1, that is, the total power value (total power consumption value) consumed in the house H, based on the measurement result of CT1.

  The power measuring device 4 has a wireless communication interface, and is communicatively connected to the control device 2 via a wireless network (not shown) built in the house H. This wireless network is, for example, a network conforming to ECHONET Lite. The power measuring device 4 may be connected to this wireless network via an external communication adapter (not shown).

  In response to the request from the control device 2, the power measurement device 4 generates measurement data in which the measured power value of the power line D1 is stored and transmits it to the control device 2. The device address of the power measuring device 4, the ID (identification) of the power line, and the measurement time are also stored in this measurement data. The power measurement device 4 may voluntarily transmit the measurement data to the control device 2 at regular time intervals (for example, 30 second intervals). Further, the control device 2 may manage the time when the measurement data is received from the power measuring device 4 as the measurement time corresponding to the measurement data.

  The electric devices 5 (electric devices 5-1, 5-2, ...) Are, for example, electric devices such as an air conditioner, an illuminator, a floor heating system, a floor cooling / heating system, a refrigerator, an IH (Induction Heating) cooker, a television, and a water heater. Equipment. The electric devices 5-1, 5-2, ... Are installed in the house H (including the site), and are connected to the power lines D2, D3, ... Branched from the power line D1 by the distribution board 7, respectively. Each electric device 5 is communicably connected to the control device 2 via the above-described wireless network (not shown). The electric device 5 may be connected to this wireless network via an external communication adapter (not shown).

  As shown in FIG. 2, the control device 2 includes a CPU (Central Processing Unit) 20, a communication interface 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, and a secondary storage device 24. Equipped with. These components are connected to each other via a bus 25. The CPU 20 centrally controls the control device 2. Details of the functions realized by the CPU 20 will be described later.

  The communication interface 21 is configured to include a network card for wireless communication with the power measuring device 4 and each electric device 5 via the above-described wireless network, and a network card for wireless or wired communication with the operation terminal 3. It

  The ROM 22 stores a plurality of firmware, data used when these firmwares are executed, and the like. The RAM 23 is used as a work area of the CPU 20.

  The secondary storage device 24 is composed of an EEPROM (Electrically Erasable Programmable Read-Only Memory), a readable / writable nonvolatile semiconductor memory such as a flash memory, an HDD (Hard Disk Drive), and the like. As illustrated in FIG. 3, the secondary storage device 24 stores a power management program 240, a target value DB 241, a performance DB 242, and a power adjustment schedule 243.

  In addition to this, the secondary storage device 24 is a program for monitoring the operating state of each electric device 5 and controlling the operation of each electric device 5 as desired by the user, and these programs. The data and the like used when executing

  The power management program 240 is a computer program executed by the CPU 20. The power management program 240 describes processing related to power management.

  The target value DB (target value database) 241 is a database that stores target values of power consumption. The target value stored in the target value DB 241 includes the target value (first target value) for the year (first period), the target value (second target value) for each month (each divided period), and each day. The target value (third target value) is included.

  Although details will be described later, the CPU 20 calculates the first target value by multiplying a predetermined reference power amount by a coefficient (household coefficient) obtained based on the characteristics of the household living in the house H. For example, when the reference power amount is 8000 [kwh] and the household coefficient is 0.6, the first target value is 4800 [kwh].

  The CPU 20 determines the second target value of each month by distributing the calculated first target value to each month based on the air conditioning load predicted in each month of January to December. FIG. 4 shows an example of the second target value for each month.

  Then, the CPU 20 determines the third target value for each day in each month based on the calculated second target value for each month and the actual power consumption in the house H (demand area).

  The record DB (record database) 242 is a database that stores the record of the power consumption of the house H, more specifically, the history of the total power consumption value of the house H. The CPU 20 updates the performance DB 242 based on the measurement data from the power measuring device 4 acquired at regular time intervals.

  The power adjustment schedule 243 is data in which a schedule indicating a timetable of an allowable value of total power consumption in one day is stored. In the power adjustment schedule 243, a time zone and an allowable value (unit is [kw]) are stored in association with each other. The power adjustment schedule 243 is created by the CPU 20 at a predetermined time every day (for example, midnight), and is stored in the secondary storage device 24. FIG. 5 shows an example of a timetable of the allowable value of the total power consumption in one day.

  FIG. 6 is a block diagram showing a functional configuration of the control device 2. Functionally, the control device 2 includes a user interface unit 200, a power acquisition unit 201, a target value determination unit 202, a schedule creation unit 203, and a device control unit 204. These functional units are realized by the CPU 20 executing the power management program 240 stored in the secondary storage device 24.

  The user interface unit 200 performs a user interface process via the operation terminal 3. That is, the user interface unit 200 receives information indicating a user operation (user operation information) via the operation terminal 3. In addition, the user interface unit 200 transmits information (operation screen information) for presenting an operation screen to the user to the operation terminal 3.

  The power acquisition unit 201 performs a process of acquiring the measured power value from the power measuring device 4. Specifically, the power acquisition unit 201 requests the power measurement device 4 to transmit measurement data at regular time intervals (for example, 30-second intervals). The power acquisition unit 201 acquires the measurement data sent from the power measurement device 4 in response to the request. The power acquisition unit 201 updates the performance DB 242 based on the acquired measurement data.

  As described above, the target value determination unit 202 (first target value determination means, second target value determination means, and third target value determination means) uses the target value (first period) of the power consumption amount (first period). The target value), the target value (second target value) of each month (each divided period) of the year, and the target value (third target value) of each day of each month are determined. When the user performs a predetermined operation for setting the target value, the target value determination unit 202 displays a household information input screen (not shown) on the operation terminal 3 via the user interface unit 200.

  The household information input screen is an operation screen for accepting input of household information from a user such as a householder. The household information includes the number of households, the age of each person, household annual income, information indicating a living area, and the like. The target value determination unit 202 determines the above-mentioned household coefficient based on the household information input on the household information input screen.

  Specifically, the target value determination unit 202 determines a coefficient correction value for each item (household size, household composition, income level, climate type) of household characteristics obtained from household information. Here, household size (small, standard or large), household composition, income level (low, standard or high) and climate type (cold or warm) are the number of households, their age, annual household income and Obtained from the residential area. Each coefficient correction value according to the size of the household, household composition, income level, and climate type is set in advance.

  The target value determination unit 202 determines the household coefficient by adding the total of the determined coefficient correction values to the reference coefficient (“1” in this embodiment). FIG. 7 shows an example of the relationship between the content of each item of household characteristics and the coefficient correction value.

  In FIG. 7, in the example of pattern 1, “household size” is “standard”, “household composition” is “young to middle age”, “income level” is “standard”, and “climate” It indicates that the coefficient correction values when the “type” is “warm” are “0”, “−0.2”, “−0.1”, and “−0.1”. Here, the household composition "young to middle-aged" indicates that the household is composed of people in the age group from young (15 to 29 years old) to middle-aged (30 to 50 years old). . In pattern 1, when the coefficient correction values of the respective items are summed up, it becomes “−0.4”, so the household coefficient becomes “0.6 (1 + (− 0.4))”.

  Further, in the example of pattern 2, “household size” is “large”, “household composition” is “child, middle-aged, and elderly”, “income level” is “high”, It shows that the coefficient correction values when the "climate type" is "cold" are "0.1", "-0.1", "0", and "0". Here, the household composition is "child, middle-aged, and old-age" when the household is child (6 to 14 years old), middle-aged (30 to 50 years old), and elderly (51 to 64 years old). It shows that it is composed of people. In pattern 2, when the coefficient correction values of the respective items are summed up, the value becomes "0", and the household coefficient becomes "1 (1 + 0)".

  In the example of pattern 3, “household size” is “small”, “household composition” is “elderly”, “income level” is “low”, and “climate type” is “cold”. It is shown that the respective coefficient correction values in the case of “” are “−0.1”, “0”, “−0.2”, and “0”. Here, the term "elderly" in the household composition means that the household is composed of only elderly people (65 years old or older). In pattern 3, when the coefficient correction values of the respective items are summed up, it becomes “−0.3”, so the household coefficient becomes “0.7 (1 + (− 0.3))”.

  The target value determination unit 202 determines the first target value by multiplying the household coefficient determined as described above by the reference power amount (for example, 8000 [kwh]). Here, the reference power amount may be fixed, or may be set appropriately by the user via the household information input screen or the like. At that time, the user may input the target amount of the annual electricity bill instead of the electric power amount. In this case, the target value determining unit 202 may calculate the reference power amount [kwh] from the input target amount and the average unit price of the electricity charges.

  When the first target value is determined as described above, the target value determination unit 202 causes the coefficient (air conditioning) based on the air conditioning load predicted in each divided period (January to December) obtained by dividing the first period (annual). Load factor). The air conditioning load coefficient is calculated based on the cooling / heating coefficient, the temperature coefficient, and the operation coefficient. In the present embodiment, the cooling / heating coefficient is “2” as the cooling period when the average temperature is 21 ° C. or higher, and is “2” when the average temperature is 10 ° C. or lower as the heating period. "It becomes. In the case of a month in which the average temperature is 10 ° C to 21 ° C, the cooling / heating coefficient is "1", which means that the cooling / heating is not required.

  In this embodiment, the temperature coefficient is obtained by dividing | monthly average temperature−annual average temperature | by the annual average temperature. The information about the local average monthly temperature may be input by the user via the operation terminal 3, or the control device 2 may be acquired from an external server via a wide area network such as the Internet.

  In the present embodiment, the operating coefficient is obtained by multiplying the number of air conditioners (or the number of rooms in which air conditioners are installed) by “0.1”. However, the operation coefficient of the month corresponding to the period when air conditioning is not required is "0". Information regarding the number of air conditioners owned by the household, that is, the number of air conditioners installed in the house H (or the number of rooms in which the air conditioners are installed) is used as the information for managing the electric device 5 in the secondary storage device 24. Remembered in. In addition to the air conditioner, the electrical equipment that is the target for deriving the operation coefficient may include an electrical equipment 5 for cooling and heating such as a floor heating system and a floor cooling / heating system.

  The target value determination unit 202 calculates the air conditioning load coefficient for each month by summing the cooling / heating coefficient, the temperature coefficient, and the operation coefficient obtained as described above. Then, the target value determination unit 202 determines the second target value for each month by distributing the first target value based on the air conditioning load coefficient for each month. For example, if the monthly average temperature of the area is as shown in FIG. 8 and the first target value is 4800 [kwh] and there are three air conditioners (or there are three rooms with air conditioners installed), The second target value is as shown in FIG.

  In addition, in the heating period, a case where an air conditioner is not used, such as an oil stove, may be assumed. In this case, even if the average temperature is 10 ° C. or less, the cooling / heating coefficient is set to “1” because the cooling / heating is not required. In this case, the monthly average temperature of the area is as shown in FIG. 8, and assuming that the first target value is 4800 [kwh] and there are three air conditioners (or three rooms with air conditioners installed), The second target value of is as shown in FIG.

  When the second target value for each month is determined as described above, the target value determination unit 202 determines the third target value for each day in each month. More specifically, the target value determination unit 202 allocates the determined second target value in each month on each day of the month based on the actual power consumption of the house H (demand area). Determine the third daily target. Specifically, the target value determination unit 202 determines the third target value for each day by using the actual power consumption amount for each day of the week, which is obtained by referring to the actual result DB 242.

  Here, the actual power consumption for each day of the week may be the average of the power consumption of each day of the week in the past several months from the present, or the average of the power consumption of each day in the past several weeks from the present. It may be. Alternatively, the result of the last week or the result of each day of the week of the previous year may be adopted, or the average of the amount of power consumption of each day of the month from installation of the control device 2 to the previous year may be adopted. Good.

  The target value determination unit 202 registers the first target value, the second target value of each month, and the third target value of each day of each month, which are determined as described above, in the target value DB 241.

  The schedule creation unit 203 is activated at a predetermined time every day (for example, midnight), and creates a schedule (power adjustment schedule 243) indicating a timetable of the allowable value of the total power consumption for the next day. More specifically, the schedule creation unit 203 creates the power adjustment schedule 243 based on the third target value corresponding to the day and the record of power consumption in the house H (demand area). Specifically, the schedule creation unit 203 creates the power adjustment schedule 243 using the tendency of the daily power consumption derived from the history of the power consumption in the past fixed period. In this case, the schedule creation unit 203 derives the tendency of the daily power consumption from the history of the power consumption in the past fixed period according to the type of the day (weekday, holiday).

  The schedule creation unit 203 sets an allowable value of the total power consumption for each predetermined time width (for example, 2 hours) based on the third target value corresponding to the day and the derived tendency of the power consumption of the day. By allocating, the power adjustment schedule 243 is created (see FIG. 5).

  The time width to which the allowable value is assigned is arbitrary, and may be every hour or so-called demand time period (30 minutes). In addition, the above-mentioned time width does not have to be constant, and for example, the above-mentioned time width may be shorter than the user's absent schedule period in the user's scheduled home period.

  The schedule creation unit 203 saves the created power adjustment schedule 243 in the secondary storage device 24.

  The device control unit 204 (adjustment command means) compares the total power consumption value acquired from the power measuring device 4 with the allowable value corresponding to the current time shown in the power adjustment schedule 243, and the total power consumption value is allowable. When the value is equal to or more than the value, an electric power adjustment command is transmitted to each electric device 5. In addition, the device control unit 204 can also operate the specified electric device 5 with the specified contents in accordance with a user operation via the operation terminal 3.

  FIG. 10 is a flowchart showing the procedure of the target value determination processing executed by the target value determination unit 202 of the control device 2. The target value determination process is started by the user performing a predetermined operation for setting the target value.

  The target value determination unit 202 instructs the operation terminal 3 to display a household information input screen (not shown) via the user interface unit 200 (step S101). When the user completes the input operation on the household information input screen (step S102; YES), the target value determination unit 202 determines and determines the above-mentioned household coefficient based on the input household information (step S103). The first target value is determined by multiplying the household coefficient by the reference power amount (step S104).

  The target value determination unit 202 determines the air conditioning load coefficient for each month (January to December) (step S105), and distributes the first target value based on the air conditioning load coefficient for each month, thereby obtaining each month. The second target value of is determined (step S106).

  Then, the target value determination unit 202 determines the third target value for each day based on the determined second target value for each month and the actual power consumption (step S107).

  FIG. 11 is a flowchart showing the procedure of the power management process executed by the control device 2.

  When the power acquisition unit 201 acquires the power value, that is, the total power consumption value from the power measurement device 4 at N-second (for example, 30 seconds) intervals (step S201; YES), the device control unit 204 refers to the power adjustment schedule 243. Then, the allowable value corresponding to the current time is acquired (step S202). Then, the device control unit 204 determines whether or not the total power consumption value is equal to or greater than the allowable value (step S203).

  When the total power consumption value is less than the allowable value (step S203; NO), the device control unit 204 does not send the power adjustment command to any of the electric devices 5, and then the total power consumption from the power measuring device 4 is reached. Wait until you get the value.

  On the other hand, when the total power consumption value is equal to or greater than the allowable value (step S203; YES), the device control unit 204 broadcasts a power adjustment command to each electric device 5 (step S204).

  Each electric device 5 that has received the adjustment command transmitted from the control device 2 reduces its own operating capability and reduces power consumption.

  FIG. 12 shows a communication sequence between the power measuring device 4, the control device 2 and each electric device 5.

  As described above, in the power management system 1 according to the embodiment of the present invention, the control device 2 uses the household coefficient obtained based on the characteristics of the household living in the house H to determine the upper limit of the annual power consumption. The first target value indicating is determined. Then, the control device 2 determines the second target value of each month by distributing the determined first target value to each month based on the air conditioning load predicted in each month of January to December. Therefore, the target value indicating the upper limit of the long-term (annual or monthly) power consumption can be set to an appropriate value according to the actual situation of the consumer.

  Further, the control device 2 determines the third target value for each day in each month based on the calculated second target value for each month and the actual power consumption of the house H (demand area). Therefore, the upper limit of power consumption on each day can be set to an appropriate value according to the actual conditions of the household.

  Further, the control device 2 creates a schedule (power adjustment schedule 243) indicating a timetable of the allowable value of the total power consumption for the next day based on the third target value corresponding to the day and the actual power consumption. . Then, the control device 2 adjusts the power according to the power adjustment schedule 243 thus created. Therefore, it is possible to realize effective power saving control while suppressing user discomfort and inconvenience.

  The present invention is not limited to the above embodiment, and various modifications can of course be made without departing from the gist of the present invention.

  For example, the target value determination unit 202 may determine the second target value in each divided period in which the first period (annual) is divided into a plurality of months (for example, 2 to 4 months). Furthermore, the lengths of the divided periods need not be the same.

  Further, the target value determination unit 202 does not need to determine the target value (third target value) of each day of each month immediately after the determination of the second target value of the month. The third target value for each day may be determined, for example, the day before the start date of the month, or midnight of the start date of the month.

  In addition, the schedule creation unit 203 may update the power adjustment schedule 243 as appropriate. As shown in FIG. 13, even if the power is adjusted according to the power adjustment schedule 243, the integrated value of the power consumption predicted based on the power adjustment schedule 243 and the integrated value of the actual power consumption are There can be situations where there is a divergence. Therefore, the schedule creation unit 203 adjusts the power when the deviation between the predicted integrated value of power consumption (predicted value) and the actual integrated value of power consumption (actual value) is equal to or greater than a predetermined value. The schedule 243 is updated.

  For example, the schedule creation unit 203 updates the power adjustment schedule 243 by correcting the allowable value according to the following expression 2 when the following expression 1 is satisfied.

  (Actual value (t) -predicted value (t)) / third target value × 100 ≧ 5 (Equation 1)

  Allowable value (t + 1) = (third target value−actual value (t)) / (third target value−predicted value (t)) × allowable value (t) (Equation 2)

  Further, the control device 2 may be configured to further include an input device for receiving an operation from a user and a display device for presenting information to the user.

  In the above embodiment, the case where the control device 2 is installed in the house H has been described, but a device having the same function as the control device 2 may be installed outside the house H.

  An example of this case is shown in FIG. In this example, a router 8 is installed in the house H instead of the control device 2. On the other hand, outside the house H, a server 9 is installed which is communicably connected to the router 8 via the Internet. In this case, the router 8 and the server 9 cooperate and play the same role as the control device 2.

  In the above embodiment, the CPU 20 executes the power management program 240 stored in the secondary storage device 24 to implement each functional unit (see FIG. 6) of the control device 2. However, all or some of the functional units of the control device 2 may be realized by dedicated hardware. The dedicated hardware is, for example, a single circuit, a composite circuit, a programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof.

  In the above embodiment, the power management program 240 is a CD-ROM (Compact Disc Read Only Memory), a DVD (Digital Versatile Disc), a magneto-optical disc (Magneto-Optical Disc), a USB (Universal Serial Bus) memory, a memory card. , And can be stored in a computer-readable recording medium such as an HDD and distributed. By installing the power management program 240 distributed in this way in a specific or general-purpose computer, it is possible to cause the computer to function as the control device 2 in the above-described embodiment.

  Alternatively, the power management program 240 may be stored in a disk device or the like of a server on a network such as the Internet, and the power management program 240 may be downloaded from the server to a computer.

  The present invention can be variously embodied and modified without departing from the broad spirit and scope thereof. Further, the above-described embodiment is for explaining the present invention, and does not limit the scope of the present invention. That is, the scope of the present invention is indicated by the scope of the claims, not the embodiments.
