The server 1 may be at least one of a personal computer and a mobile terminal, or may be a combination of a plurality of devices via a network as appropriate.

The server 1 is installed in an electric power company (including related organizations such as subsidiaries).
The server 1 includes display means 2 for displaying information, etc., input means 4 for accepting input of information, etc., storage means 6 for storing information, etc., communication means 7 connectable to a dedicated line EL and the Internet IN, and a control means 8 for controlling these. For example, the display means 2 is a monitor, the input means 4 is at least one of a keyboard and a pointing device, the storage means 6 is at least one of a memory and a hard disk, and the communication means 7 is connected to a dedicated line EL and Internet IN. possible communication unit, and the control means 8 is a CPU.
Incidentally, the communication means 7 may be separated between the connecting portion of the private line EL and the connecting portion of the Internet IN. Also, if either the dedicated line EL or the Internet IN is not used, the unused portion may be omitted.

The communication means 7 is connected to the aggregation server CC installed in the electric power company via a dedicated line EL. Note that the aggregation server CC may be installed at another location or organization. Also, the server 1 may be connected to the total server CC via the Internet IN or the like.
A plurality of smart meters SM are connected to the aggregation server CC. Here, each smart meter SM is connected to the aggregation server CC via a wireless communication network or the like. Note that each smart meter SM may be connected to the aggregation server CC via the Internet IN, or may be connected via a mobile phone network or the like.
Each smart meter SM is a power meter that is installed in a household that consumes electricity (a household that has concluded a power supply contract) and is capable of measuring the amount of electricity consumed by the household. It is possible to calculate the power consumption by time zone by accumulating the power consumption for each time zone (48 time zones per day), attach the household identification information (household ID), and transmit it to the aggregation server CC. . Each hourly power consumption with a household ID is a so-called A root value. In addition, in the case of a two-family house, a plurality of smart meters SM may be installed in one building.
The aggregation server CC has a power consumption database in which household IDs, types of time slots (dates and times pertaining to time slots), and power consumption amounts for each time slot are associated with each other.

Further, the communication means 7 is connected to the outside air temperature server TC, the night time server NC, and the solar radiation amount server LC via the Internet IN.
The outside temperature server TC is, for example, a server computer installed by a meteorological observation organization. When an inquiry is made by designating an area and date, the daily average outside temperature observed in that area and date is sent. The outside air temperature may be the lowest temperature, the highest temperature, or the like, a combination thereof, or the average weekly temperature.
The night time server NC is, for example, a server computer installed by the same organization as the outside air temperature server TC or by a different organization. When an inquiry is made by designating an area and date, the night time in that area and date is sent. Here, night time is the time from sunset on the date to sunrise on the next morning, and night time is the time from sunset on the previous day to sunrise on the date. It may be a time indicating another nighttime. Also, the night time may be calculated by the control means 8 according to the area and the date, or may be stored in the storage means 6 as a night time database.
The solar radiation server LC is, for example, a server computer installed by the same organization as the other servers or by a different organization. The slope solar radiation amount at the angle is transmitted. At least one of the amount of solar radiation on the slope and the amount of global solar radiation may be calculated by the control means 8 according to the area and date or the angle of the slope, or may be stored in the storage means 6 as a solar radiation amount database. good. Moreover, at least any two of the outside air temperature server TC, night time server NC, solar radiation server LC and totalization server CC may be a common server.

Furthermore, the communication means 7 is connected with the terminal T via the Internet IN.
The terminal T is a portable terminal here, and similarly to the server 1, it has a display means 12 for displaying information, etc., an input means 14 for receiving input of information, etc., a storage means 16 for storing information, etc., and a communication means. 17 and control means 18 for controlling them. The display means 12 and the input means 14 are, for example, a display with a touch sensor, the storage means 16 is, for example, a memory, and the communication means 17 is, for example, a communication unit connected to a mobile phone network for data communication, The control means 18 is a CPU.
The storage means 16 of the terminal T stores a usage decomposition application (a usage decomposition application, a terminal-side usage decomposition program) that cooperates with the usage decomposition program of the server 1, and the control unit 18 can execute the usage decomposition application. . The usage decomposition application is associated with the user's household (the smart meter of the household) and holds the household ID. It should be noted that the household ID in the terminal T and the household ID in the server 1 may be different, and a correspondence table between them may be stored in the server 1 or the like.
At least one of the outside air temperature server TC, night time server NC, solar radiation server LC, and terminal T may be connected to the server 1 via a route other than the Internet IN, such as a private line EL or local communication. Various communication paths may include wired or wireless. Also, the terminal T may be a PC (personal computer) placed in the user's household or the like.

The application decomposition program is stored in storage means 6 and executed by control means 8 .
The application decomposition program calculates the total power consumption, which is the total power consumption for the target period, from each power consumption of the household ID related to the acquired target household, and calculates the total power consumption for the cooling and heating in the target period from the total power consumption. It has a function to decompose (disaggregate) and determine the power consumption for each application, such as the power consumption for cooling and heating, which is the power consumption of the equipment.
Air-conditioning equipment is an electrical equipment that regulates the indoor thermal environment (at least one of temperature, humidity, airflow and heat radiation). can be included.

≪Internal configuration and example of operation, etc.≫
[Start of processing, etc.]
FIG. 2 is a flow chart of a usage decomposition program and a usage decomposition application, which are executed to cause the power consumption usage decomposition system D1 to operate.
By executing the application decomposition application on the terminal T, the control means 18 performs initial setting processing (step S1). If the initial setting has been completed, the control means 18 skips step S1 and proceeds to step S2.
In step S1, the control means 18 controls the number and types of refrigerators owned by the user (household) (here, three types: large refrigerator, small refrigerator, and freezer only), presence/absence of an IH cooking heater, presence/absence of a rice cooker, an electric pot, and so on. (including electric kettle), presence/absence of dishwasher, presence/absence and type of electric water heater (heat pump type (HP type), heater type (electric water heater) here), heater type for water heater Input each information related to at least one of the number of people in the household, the amount of hot water stored, and the output of the heater when accept. The input is performed by selecting the pull-down list displayed on the display means 12 by the input means 14, for example. When the user inputs all the information (for example, when the input completion button is pressed with all the pull-down lists selected), the control means 18 stores each information in the storage means 16 .

Next, in step S2, a period selection section (for example, a pull-down list) and a use decomposition execution button are displayed on the display means 12, and the user designates the target year and month using the input means 14 of the terminal T and selects the use decomposition execution button. When is pressed, the control means 18 sends an instruction to execute the application decomposition program along with the household ID and the period to the server 1 via the communication means 17 . When the initial setting (step S1) is performed, each information related to the initial setting is also transmitted to the server 1. FIG.
The period is designated to obtain the total power consumption and the power consumption by application decomposed therefrom, and here is one month (for example, January 2018). The period may start on the 26th and end on the 25th of the following month, or it may be adjusted to the electricity rate calculation period, or it may be of another length such as one week or two months. It can be.
When the control means 8 of the server 1 receives the command to execute the usage decomposition program, the household associated with the household ID is set as the target household to be subjected to usage decomposition, and the specified period is set as the target period (here, one month). Run the usage decomposition program. When receiving each information of the initial setting, the control means 8 stores it in the storage means 6 in association with the household ID.

[Calculation of total power consumption, etc.]
First, the control means 8 requests the collection server CC to transmit all hourly power consumption amounts within the target period for the household ID of the target household. The aggregation server CC finds out the requested power consumption by time period from the power consumption database, and transmits it to the server 1 . The control means 8 of the server 1 stores the power consumption for each time zone received by the communication means 7 in the storage means 6 (step S3). For example, in the case of January 2018, the control means 8 controls the period from January 1, 1st time zone (00:00 to 0:30) to 31st, 48th time zone (23:30 to 24:00). Get the power consumption for each time period up to .
Then, the control means 8 sums up all power consumptions by time period to obtain the total power consumption, which is the power consumption of the target household for the entire target period, and stores it (step S4).

[Energy Consumption by Use of Refrigerators, etc.]
Next, the control means 8 calculates the power consumption for each application of the refrigerator (step S5). Here, various power consumptions by application are once calculated for each unit period (one day) within the target period, and then added up over the target period. Note that the order of calculating the power consumption for each application is not limited to the following, and may be changed as appropriate, or some or all of them may be calculated at the same time.

FIG. 3 is a flowchart showing details of step S5.
First, the control means 8 sets the annual refrigeration power consumption according to the type of refrigerator obtained at the time of initial setting (step S101).
Here, the annual refrigeration power consumption is set to 420 kWh (kilowatt hours) for a large refrigerator, 370 kWh for a small refrigerator, and 335 kWh for a freezer only, per unit.
Such set values are determined, for example, from at least one of the average specifications (catalog specifications) of major refrigerator manufacturers several years ago and official documents such as the energy saving performance catalog issued by the Agency for Natural Resources and Energy of the Ministry of Economy, Trade and Industry.

Next, the control means 8 determines the distribution ratio of the annual refrigeration power consumption in the summer (here, the average daily temperature is 15° C. or higher as the outside temperature) and in the winter (here, the average daily temperature is below 15° C.). It is calculated according to the ratio between the number of days in summer and the number of days in winter in the region to which the target household belongs, which is obtained from the TC (step S102). A year may start in January, may start in April, may start one year before the current year, or may start in another year, and so on. .
Here, the distribution ratio of the annual refrigeration power consumption in summer: the distribution ratio of the annual refrigeration power consumption in summer=1.5:1.0.
Note that the distribution ratio may be a fixed value (for each region) stored in the storage means 6 . Also, the distribution ratio may not be taken into consideration.

Subsequently, the control means 8 determines that the unit refrigeration power consumption, which is the refrigeration power consumption per day (unit period), is a function of a predetermined shape (unit refrigeration function) related to the daily average temperature, as shown in FIG. ), the function is determined (step S103).
That is, the shape of the function is a constant value below the first predetermined temperature (here, 2° C. determined recursively), and above the first predetermined temperature, the second predetermined temperature (here, recursively determined 28° C.) ℃) below is a linear function, assumed to take a constant value when the second predetermined temperature is exceeded, annual refrigeration power consumption and its distribution ratio (for large refrigerators, 1.35 kWh/day in summer, 0.902 kWh in winter /day), the unit refrigeration function in the target household is determined.

Then, the control means 8 acquires the daily average temperature for each day in the target period from the outside temperature server TC, applies them to the unit refrigeration function, and calculates the refrigeration power consumption (unit refrigeration power consumption) for each day. . In addition, the control means 8 totals these over the target period to calculate the refrigeration power consumption (step S104). The daily average temperature, the unit refrigeration power consumption, and the refrigeration power consumption for the target period are stored in the storage means 6 . Hereinafter, it is assumed that various values during calculation and various calculated values are stored in the storage means 6 even if they are not specified each time. Various values in the middle of calculation may be temporary values that are stored only at the time of calculation or the like.
If the unit refrigerating function has already been determined, the control means 8 may refer to the memory to execute only step S104. In this case, the unit refrigerating function may be re-determined periodically (every year, etc.) or irregularly (when the terminal T issues an initialization command, etc.).

[Electric power consumption, etc. by lighting application]
Next, the control means 8 calculates the unit lighting power consumption related to the lighting power consumption by application (step S6).

FIG. 5 is a flowchart showing details of step S6.
First, the control means 8 calculates the annual power consumption by obtaining the power consumption for each time zone for the target household for one year from the aggregation server CC, and adding up the power consumption. ) to calculate the annual lighting power consumption (annual lighting power consumption) (step S201).
Here, the predetermined percentage is set at 13.4% with reference to the Agency for Natural Resources and Energy's "Actual State of Home Energy Consumption".
If the power consumption for each time period is less than one year, for example, the control means 8 multiplies the power consumption for one month by 12, multiplies the power consumption for two months by 6, or The annual power consumption may be obtained by referring to a predetermined value corresponding to the type of building, and so on.

Next, the control means 8 obtains the nighttime hours for each day of the year in the area of the target household from the nighttime server NC, and totals them to calculate the annual nighttime hours (minutes) (step S202). ). The control means 8 may receive the night time itself from the night time server NC, or may receive the sunset time and sunrise time from the night time server NC and calculate the night time from these.
Note that the night time may be a fixed value (for each region) stored in the storage means 6 .

Subsequently, the control means 8 divides the annual lighting power consumption obtained in step S201 by the annual nighttime hours obtained in step S202, and calculates the lighting power consumption per minute (minute lighting power consumption) in the target household. , element lighting power consumption) are calculated (step S203). Incidentally, the element lighting power consumption may be per 30 seconds, 2 minutes, 30 minutes, or the like.

Then, the control means 8 multiplies the night time in the target period, which is obtained from the night time server NC, by the amount of lighting power consumption obtained in step S203, and obtains the unit lighting power consumption, which is the lighting power consumption of the day. The amount is calculated (step S204). In addition, the control means 8 adds up the unit lighting power consumption in the target period to calculate the lighting power consumption in the target period.
As in the case of the refrigerator, the control means 8 may execute only step S204 by referring to the previously described amount of lighting power consumption, or may recalculate the amount of lighting power consumption, and so on. is.
In addition, the control means 8 determines that the target household is absent during the target period when the total power consumption, which is the power consumption of the target household over the target period, is less than a predetermined upper limit (here, 15 kWh determined inductively). and set the unit lighting power consumption to 0. This process may be omitted.

[Electric power consumption by application of electric cookware, etc.]
Subsequently, the control means 8 calculates the power consumption of each unit cooking appliance (IH cooking heater, rice cooker, electric pot, dishwasher) for each application (step S7).

FIG. 6 is a flowchart showing details of step S7.
The control means 8 refers to the information acquired at the time of initial setting, and if the target household does not have an IH cooking heater (No in step S301), the next step S302 is skipped, and if there is an IH cooking heater (step S301 Yes), the next step S302 is performed.
In step S302, the control means 8 sets the unit cooking appliance (IH cooking heater) power consumption, which is the cooking appliance (IH cooking heater) power consumption per day, to a predetermined value. Further, the control means 8 multiplies the unit cooking appliance (IH cooking heater) power consumption by the number of days in the target period to calculate the cooking appliance (IH cooking heater) power consumption in the target period.
The predetermined value is 0.67 kWh/day obtained by actually measuring a plurality of sample households and averaging them.
As in the case of the lighting, the control means 8 sets the power consumption of the unit cooking appliance (IH cooking heater) to 0 when the absence is determined, and so on. Also, here, the presence or absence of IH cooking heaters is referred to, and the number of units is not taken into consideration.

Next, the control means 8 similarly performs the next step S304 only when there is a rice cooker (Yes in step S303).
In step S304, the control means 8 multiplies the annual power consumption, which is the annual power consumption of the target household, by a predetermined ratio (2.3% with reference to the Agency for Natural Resources and Energy "Actual State of Home Energy Consumption") The annual power consumption of the cooker (rice cooker) is calculated and divided by the number of days per year (365) to obtain the unit power consumption of the cooker (rice cooker). Further, the control means 8 multiplies the unit cooking appliance (rice cooker) power consumption by the number of days in the target period to obtain the cooking appliance (rice cooker) power consumption in the target period.

Subsequently, similarly, the control means 8 performs the next step S306 only when there is an electric pot (Yes in step S305).
In step S306, the control means 8 multiplies the annual power consumption by a predetermined percentage (3.2% in reference to the same document) to calculate the annual power consumption of the cookware (electric pot), and divides this into the number of days per year. By dividing, the unit cooking utensil (electric pot) power consumption is obtained. Further, the control means 8 multiplies the unit cooking appliance (electric pot) power consumption by the number of days in the target period to obtain the cooking appliance (electric pot) power consumption in the target period.

Further, the control means 8 similarly performs the next step S308 only when there is a dishwasher (Yes in step S307).
In step S308, the control means 8 multiplies the annual power consumption by a predetermined percentage (3.7% in reference to the same document) to calculate the annual power consumption of cooking utensils (dishwashers), and calculates this as the number of days per year. By dividing by , the unit cooking utensil (dishwasher) power consumption is obtained. Further, the control means 8 multiplies the unit cooking appliance (dishwasher) power consumption by the number of days in the target period to obtain the cooking appliance (dishwasher) power consumption in the target period.

[Energy Consumption of Heat Pump Water Heaters by Application]
Next, the control means 8 calculates the unit HP hot water supply power consumption related to the application-specific power consumption of the HP water heater (step S8).

FIG. 7 is a flowchart showing details of step S8.
The control means 8 multiplies a predetermined coefficient a determined for each target household by the daily average temperature x to obtain a unit HP hot water supply power consumption y, which is the HP hot water power consumption for one day, by a predetermined constant determined for each target household. Assuming that it is represented by a linear function y=ax+b (unit HP hot water supply function) to which a certain intercept b is added, the coefficient a and the intercept b are calculated as follows (step S401). Here, the fact that the unit HP hot water supply power consumption y is represented by the unit HP hot water supply function is based on the results of analysis of 200 or more sample households (different from the sample households described above) having HP water heaters. Regarding the assumption that the unit HP hot water supply power consumption y is represented by the unit HP hot water supply function, 85% of all households have a correlation coefficient of 0.7 or more, so this assumption is quite valid. have
That is, for the 200 or more sample households, as shown in FIG. 8, the value of each sample household is plotted on a graph where the vertical axis is the coefficient a and the horizontal axis is the annual maximum value M of the unit HP hot water supply power consumption. When plotting the set, it was found that the coefficient a tended to follow a linear function with a downward sloping curve. was found as indicated by the dotted line in .
Similarly, for the intercept b, as shown in FIG. 9, a set of values for each sample household is plotted on a graph with the intercept b on the vertical axis and the annual maximum value M of the unit HP hot water supply power consumption on the horizontal axis. , the intercept b tended to follow a linear function rising to the right, so by the least squares method, the linear function for the intercept b was found as shown by the dotted line in FIG. . Note that R in FIGS. 8 and 9 is a correlation coefficient.
Therefore, the control means 8 can calculate both the coefficient a and the intercept b by the linear functions described above, once the annual maximum value M of the unit HP hot water supply power consumption is acquired. However, it is difficult to obtain an accurate actual value for the annual maximum value M of the unit HP hot water supply power consumption from the target households, unlike the time of the analysis when the cooperation of the sample households was obtained. Therefore, the control means 8 inductively assumes that the annual maximum value M of the unit HP hot water supply power consumption is a predetermined ratio of the annual power consumption, and multiplies the annual power consumption by the predetermined ratio to obtain the unit HP hot water supply power consumption. Obtain the annual maximum M of the quantity. Then, the control means 8 obtains the coefficient a and the intercept b from each linear function.
The control means 8 substitutes the unit HP hot water supply function for the target household determined in this way with the daily average temperature within the target period from the outside temperature server TC to obtain the unit HP hot water supply power consumption (step S402). . Further, the control means 8 sums up each unit HP hot water supply power consumption obtained by substituting each day's average temperature within the target period to obtain the HP hot water supply power consumption in the target period.
Note that the control means 8 may skip step S8 when information indicating that there is no HP water heater is obtained at the time of initial setting. Alternatively, the number of HP water heaters may be input at the time of initial setting, and the control means 8 may calculate the unit HP hot water supply function in consideration of the number of units or integrate the power consumption obtained from the unit HP water heater function.

[Electric power consumption of heater-type water heaters (electric water heaters) by application]
Subsequently, the control means 8 calculates the unit hot water supply power consumption related to the application-specific power consumption of the heater-type water heater (electric water heater) (step S9).

FIG. 10 is a flowchart showing details of step S9.
Electric water heaters with heater outputs of 4.5 kW and 5.5 kW are in widespread use. Such an output is also shown in FIG. If it is sufficiently large compared to other electrical equipment and the hourly power consumption exceeds 4.5/2 = 2.25 kWh or 5.5/2 = 2.75 kWh, the electric water heater is operating. It can be said that there is
Therefore, the control means 8 follows at least one of the heater output of the electric water heater, the amount of hot water stored, and the number of household members obtained in the initial setting (step S501), and the power consumption by time period on the day within the target period is The number of time periods exceeding 2.25 kWh or 2.75 kWh is counted, and the obtained number of time periods is multiplied by 2.25 kWh or 2.75 kWh to calculate the unit hot water supply power consumption (step S502). When the heater output is obtained in the initial setting, the control means 8 directly distinguishes between 4.5 kW and 5.5 kW based on the value of the heater output, and when the hot water storage amount is obtained in the initial setting. If the amount of hot water stored is 370 liters, the control means 8 will correspond to the heater output of 4.5 kW. If the number of people is less than the predetermined number (4), the control means 8 corresponds to the heater output of 4.5 kW, and if the number exceeds the predetermined number, the control means 8 corresponds to the heater output of 5.5 kW.
In addition, the control means 8 determines whether the electric power consumption by time period is within 2.25 kWh or more and less than 2.75 kWh, or whether there is a time period in which the electric water heater is 2.75 kWh or more. The heater output may be determined without referring to the initial setting information. In this case, acquisition of the heater output at the time of initial setting can be omitted. Further, the control means 8 may limit the time zone for counting the electric power consumption by time zone, etc., based on the fact that the electric water heater typically operates in the middle of the night. In this case, at the time of initial setting, information may be included as to whether or not the electric water heater in the target household operates with late-night power. In addition, the value of the heater output may be changed, for example, when an electric water heater related to a new heater output becomes popular. Furthermore, as in the case of the HP water heater, step S9 may be skipped, or a plurality of electric water heaters may be handled.

[Energy Consumption of Air Conditioning Equipment by Application]
Next, the control means 8 calculates the unit cooling/heating power consumption related to the application-specific power consumption of the cooling/heating equipment (step S10).

FIG. 12 is a flowchart showing details of step S10.
The control means 8 subtracts the unit refrigerating power consumption calculated in step S5 and subtracts the unit lighting power consumption calculated in step S6 from the unit total power consumption for a day (unit period) within the target period. , the unit HP hot water supply power consumption calculated in step S8 is subtracted, the unit hot water supply power consumption calculated in step S9 is subtracted (subtraction of various unit other-purpose power consumptions), and the unit basic power consumption is calculated. obtained (step S601).
Unit basic power consumption is calculated by subtracting from the total unit power consumption the power consumption of refrigerators, lighting, and water heaters (fluctuations), which fluctuate more depending on the season than other uses. It includes the cooling and heating part, which remains large compared to other uses, and the foundation part, where seasonal fluctuations are suppressed.

Next, the control means 8 obtains from the aggregation server CC for each time zone day in the interim season when the cooling and heating equipment is generally not used or when the power consumption is suppressed compared to other seasons. From the unit total power consumption obtained by integrating the power consumption, the unit refrigeration power consumption, unit lighting power consumption, unit HP hot water supply power consumption, and unit hot water supply power consumption calculated by the same processing as in each step are calculated. By subtracting, the mid-season unit basic power consumption is calculated (step S602).
Here, the interim season is defined as a day when the average daily temperature is 15°C or higher and 20°C or lower. In this case, in general, when a cooling and heating device such as an air conditioner is not used, or when a cooling and heating device is always in operation such as a 24-hour air conditioner, power consumption is minimized in the season.
In addition, if the total unit power consumption, etc. related to the interim season is not accumulated in the summary server CC for the target household, the day closest to the interim season (the day when the average daily temperature is ) Alternatively, a plurality of days may be substituted for the intermediate season in order of closest to the intermediate season, or a predetermined value may be substituted for the basic power consumption per intermediate season.

Subsequently, the control means 8 subtracts the midseason unit basic power consumption obtained in step S602 from the unit basic power consumption obtained in step S601 to calculate the unit cooling/heating power consumption (step S603).
Such calculations are based on graphs of the daily average temperature (horizontal axis) and the measured hourly power consumption (vertical axis) for sample households (households different from the sample households with HP water heaters described above). It can also be explained by plotting FIG. That is, the hourly power consumption has a strong tendency to be lower than other daily average temperatures when the daily average temperature is 15 to 20° C., and is distributed along a downward convex quadratic function as a whole. When the quadratic function is found by the least squares method (see the dotted line in Fig. 13), the hourly power consumption has a minimum value at 19.5°C, and the average daily temperature on both sides of the minimum value gradually increases as it moves away from the minimum value. . The minimum value corresponds to the mid-season unit basic power consumption, and is the difference between the hourly power consumption at each average temperature and the minimum value, and if the temperature is lower than 19.5°C, 30 minutes of heating. When the temperature is higher than 19.5°C, there is a high probability that it corresponds to the power consumption of cooling for 30 minutes.
In this way, only the power consumption related to cooling and heating can remain as a variable part, and from the unit basic power consumption having this and the fixed part, the influence of the power consumption related to cooling and heating is small, and the fixed part accounts for the majority By reducing the seasonal unit basic power consumption, the unit cooling and heating power consumption can be calculated simply and accurately.
In addition, the control means 8 adds up each unit cooling/heating power consumption in the target period to obtain the cooling/heating power consumption.
In addition, with the above calculation, regardless of the number of cooling and heating equipment, regardless of their capacity, or any equipment or combination of them, cooling or heating, it will be accurate. Thus, the control means 8 can accurately obtain the unit cooling/heating power consumption without obtaining the type, number, capacity, etc. of the cooling/heating equipment at the time of initial setting. Further, as described above, the cooling/heating power consumption can be set to 0 when the absence is determined.
Furthermore, the unit cooling/heating power consumption may be calculated without subtracting at least one of the unit refrigeration power consumption, unit lighting power consumption, unit HP hot water supply power consumption, and unit hot water hot water supply power consumption. If all of these are not subtracted, the unit cooling/heating power consumption is calculated from the difference between the unit total power consumption and the interseason total power consumption. Since at least one of these application-specific power consumptions is not reduced, the unit cooling/heating power consumption can be calculated more easily, although seasonal fluctuations are affected.

[Energy Consumption by Use of Standby Power, etc.]
Subsequently, the control means 8 calculates the unit standby power consumption related to the application-specific standby power consumption, which is a total of the individual standby powers of various electric devices (step S11).
The unit standby power consumption is a predetermined value determined based on the average value of the minimum annual unit total power consumption found in sample households (different from the above) (here, 93 Wh per hour for a detached house, one room 39 Wh for houses and 34 Wh for family-type housing complexes).
In addition, the control means 8 totalizes the unit standby power consumption in the target period to calculate the standby power consumption.
However, based on accumulated knowledge, if the standby power consumption in the target period is less than 10% of the total power consumption, the control means 8 sets the standby power consumption to 10% of the total power consumption.

[Other power consumption by application, etc.]
Next, the control means 8 calculates the unit other power consumption related to the other application-specific power consumption (step S12).
Unit other power consumption is divided into unit total power consumption, unit refrigeration power consumption, unit lighting power consumption, unit HP water heater power consumption, unit hot water heater power consumption, unit cooking appliances (IH cooking heater, rice cooker, Electric pots, dishwashers) Calculated by subtracting power consumption and unit standby power consumption.
In addition, the control means 8 totals the unit other power consumption in the target period to calculate the other power consumption.
However, based on accumulated knowledge, if the other power consumption in the target period is less than 2% of the total power consumption, the control means 8 sets the other power consumption to 2% of the total power consumption.
Incidentally, as described above, the other power consumption can be set to 0 at the time of absence determination.

[Adjustments, etc.]
Subsequently, the control means 8 controls unit refrigeration power consumption, unit lighting power consumption, unit HP hot water supply power consumption, unit hot water supply power consumption, unit cooking utensils (IH cooking heater, rice cooker, electric pot, dishwasher ) If the sum of power consumption, unit standby power consumption, and unit other power consumption exceeds the unit total power consumption, all unit power consumption by application shall be divided in the same ratio so that the unit total power consumption is achieved. to adjust the application-specific unit power consumption (step S13). That is, in this case, all the unit power consumptions are multiplied by the total unit power consumption/the sum.
In addition, the control means 8 controls the power consumption of refrigeration, the power consumption of lighting, the power consumption of HP hot water supply, the power consumption of hot water supply, and the power consumption of cooking appliances (IH cooking heater, rice cooker, electric pot, dishwasher) during the target period. If the sum of the consumption, standby power consumption, and other power consumption exceeds the total power consumption, all the application-specific power consumptions may be compressed at the same ratio to obtain the total power consumption. Also, the control means 8 may be compressed by multiplying a weighted ratio adjusted according to the type of power consumption for each application.

In this way, the total power consumption during the target period is divided into power consumption by application, namely, refrigeration power consumption, lighting power consumption, HP hot water power consumption, hot water hot water power consumption, cooking appliances (IH cooking heater , rice cooker, electric kettle, dishwasher) energy consumption, standby energy consumption, and other energy consumption.
The control means 8 transmits at least one of the amount of power consumption for each application and its ratio to the total power consumption to the terminal T, and the terminal T transmits this to the communication means 17 under the control of the control means 18 It is received and stored in the storage means 16 and displayed on the display means 12 . The control means 18 causes the display means 12 to display, for example, a pie chart, bar graph, or the like about the ratio. The power consumption by application may be displayed at a corresponding position or the like in the graph. A printer may be connected to the terminal T, and the graph or the like may be printed by the printer.
It should be noted that the configurations and methods relating to the calculation of various application-specific power consumption amounts can be formed or executed independently of each other. Moreover, at least one of the power consumption amounts for each application may be omitted, or new power consumption amounts for each application may be added. The classification of the power consumption by use can be changed in various ways, and for example, the power consumption by use of cooking utensils may be grouped together.

[Total power consumption, etc. when solar power generation equipment is installed]
As described above, in the power consumption application breakdown system D1, the total power consumption in the target period (one month) is broken down into power consumption by application.
However, if the target household is equipped with a solar power generation facility, it will consume the power generated by the facility and have the power company purchase the surplus power (surplus purchase) and sell the power shortage to the power company. When the smart meter SM receives the power, the smart meter SM can only obtain the amount of surplus power (also called the amount of power purchased because the power company buys it) and the amount of power shortage (similarly called the amount of power sold) for each time period. Therefore, in this case, estimate the amount of power generated by the facility, subtract the surplus power from the estimated amount of power generated, or add the power shortage to the estimated amount of power generated, and grasp the total unit power consumption. be done.
Whether or not the target household has a photovoltaic power generation facility, and if so, the panel tilt angle, panel azimuth angle, and system capacity (if there are multiple types) are input by the terminal T at the time of initial setting. It is received and transmitted, and the server 1 grasps it.
In addition, if the target household is equipped with a solar power generation facility, but the power company purchases all of the generated power (whole purchase), the power company will sell the total unit power consumption for the amount used. Unit total power consumption can be calculated as follows. Bulk purchases are rare in private households. Information indicating the mode of purchase (purchase mode information) as to whether it is a total purchase or a surplus purchase does not have to be obtained in consideration of the fact that the total purchase is rare, or may be obtained at the time of initial setting, or may be obtained from the smart meter SM or aggregation server. You may refer to what is held in the CC.

If the target household is equipped with a photovoltaic power generation facility (and the purchase mode information is surplus purchase), the control means 8, in step S3, determines the amount of surplus power for each time slot in the target period and each hour The power shortage amount for each band is acquired from the aggregation server CC.

Then, in step S4, the control means 8 estimates the power generation amount as shown in FIG. 14, calculates the unit total power consumption, and calculates the total power consumption.
That is, first, the control means 8 transmits the area of the target household and the day related to the unit total power consumption, and obtains the global solar radiation amount (horizontal solar radiation amount) from the solar radiation amount server SC (step S701).
Next, the control means 8 obtains the amount of solar radiation on the slope for each tilt angle and azimuth angle from the area of the target household, the month to which the day pertaining to the unit total power consumption belongs, the panel tilt angle, and the panel azimuth angle (step S702). . The storage means 6 stores a power generation rate database relating to the actual values of the amount of solar radiation on the slope for each region, month, panel tilt angle, and panel azimuth angle. Get solar radiation. It should be noted that the power generation rate database may be generated daily instead of monthly. Also, the power generation rate database may be located in the solar radiation server SC or another server, and the control means 8 may access the server to obtain the slope solar radiation.
Subsequently, the control means 8 calculates the power generation rate by dividing the slope solar radiation amount by the global solar radiation amount (step S703). That is, power generation rate=slope solar radiation amount/global solar radiation amount.
Next, the control means 8 multiplies the total solar radiation amount by the power generation rate, the loss coefficient of the solar panel, and the system capacity to estimate the unit power generation amount (step S704). That is, the unit power generation amount=global solar radiation amount*power generation rate*loss factor*system capacity. The loss factor here is a predetermined value (0.73). Note that the loss factor of the panel in the target household may be obtained at the time of initial setting.
Subsequently, the control means 8 adds the surplus power amount (negative value) and the deficit power amount (positive value) totaled in the unit period (one day) to the unit power generation amount to obtain the unit total power consumption amount. is calculated (step S705), and the unit total power consumption in the target period is added up to calculate the total power consumption (step S706).
In addition, when there are multiple types of panel tilt angles, panel azimuth angles, and system capacities in the target household, the control means 8 calculates the individual unit power generation amount for each type, adds them up, and calculates the unit power generation amount. can be calculated.
Also, in order to make the calculation easier, the control means 8 may calculate the amount of generated power in the target period without calculating the unit amount of generated power for each unit period. In this case, the global solar radiation averaged over one month (target period) may be obtained from the solar radiation server SC, and the global solar radiation on a typical day (for example, the central day) You can get Also, the system capacity may be one month. That is, the amount of power generated in the target period = global solar radiation (average or representative value) x power generation rate (calculated from each average or representative value of global solar radiation and slope solar radiation) x loss factor x system capacity ( period). If the surplus power (negative value) and power shortage (positive value) accumulated over the target period are added to the power generation amount during the target period, the unit power generation amount is not calculated, and the total power consumption is calculated. be done.

Thus, even in a household equipped with a photovoltaic power generation facility, an accurate total power consumption can be easily obtained, and if steps S5 and subsequent steps are similarly processed, the total power consumption can be accurately and easily obtained in the household. is broken down into energy consumption by application.

≪Effects, etc.≫

That is, the power consumption application decomposition system D1 calculates at least the cooling and heating power consumption, which is the power consumption of the cooling and heating equipment, from the total power consumption, which is the power consumption of the target household for the entire target period. Unit basic power consumption obtained by subtracting unit other-use power consumption, which is the power consumption for other purposes in the unit period, from unit total power consumption, which is the total power consumption for each unit period in the period, and generally the above It is the total power consumption per unit period in the interim season when the cooling and heating equipment is not used or the power consumption is suppressed compared to other seasons. A storage means 6 for storing the mid-season unit basic power consumption obtained by subtracting the unit other-purpose power consumption, and by subtracting the mid-season unit basic power consumption from the unit basic power consumption, A control means 8 that calculates the amount of electric power, integrates the amount of power consumption for cooling and heating for each unit period, and calculates the amount of power consumption for cooling and heating in the target period.
Therefore, in the power consumption usage decomposition system D1, the unit cooling and heating power consumption is calculated by subtracting the midseason unit basic power consumption from the target household's unit basic power consumption, and this is integrated to calculate the cooling and heating power consumption in the target period. It is possible to obtain the amount of cooling and heating power consumption that very well matches the characteristics of the target household.

In addition, the unit other-purpose power consumption includes the unit lighting power consumption, which is the power consumption of the lighting equipment in a unit period, and the control means 8 controls the unit lighting power consumption for one year in the target household. The elemental lighting power consumption, which is the element of the power consumption of the lighting equipment, obtained by dividing the total power consumption by a predetermined percentage by the nighttime hours in the area to which the target household belongs, Calculated by multiplying the night time in the unit period of the target period. Therefore, the lighting power consumption in the target period can be accurately calculated by a relatively simple calculation, reflecting the region to which the target household belongs and seasonal factors (night hours). In addition, the cooling and heating power consumption is calculated in a state where the lighting power consumption, which has seasonal fluctuations, is removed, so that the cooling and heating power consumption can be calculated more accurately.
Further, the power consumption application decomposition system D1 includes a communication means 7 capable of communicating with the night time server NC, and the communication means 7 acquires the night time from the night time server NC. Therefore, the lighting power consumption can be calculated more easily.

The control means 8 calculates the unit refrigerating power consumption by the unit refrigerating function, which is a function of the daily average temperature, and the unit refrigerating function is a linear function of the daily average temperature at 2 ° C. or higher and 28 ° C. or lower. . Therefore, the refrigeration power consumption in the target period can be accurately calculated by a relatively simple calculation, reflecting the region to which the target household belongs and the seasonal factor (daily average temperature). In addition, since the cooling/heating power consumption is calculated in a state where the refrigeration power consumption, which has seasonal variations, is removed, the cooling/heating power consumption can be calculated more accurately.
The storage means 6 stores the daily average temperature corresponding to the unit period, and the unit power consumption for other purposes is the power consumption of the HP water heater in the unit period. The control means 8 calculates the unit HP hot water supply power consumption by the unit HP hot water supply function, which is a linear function of the daily average temperature, and the coefficient and intercept of the unit HP hot water supply function are the unit HP hot water supply power consumption is determined according to the annual maximum value M in one year. Therefore, the HP hot water supply power consumption during the target period can be accurately calculated by relatively simple calculation, reflecting the region to which the target household belongs and seasonal factors (average daily temperature). In addition, the cooling and heating power consumption is calculated in a state where the HP hot water supply power consumption, which has seasonal fluctuations, is removed, so that the cooling and heating power consumption is calculated more accurately.
Further, the power consumption application decomposition system D1 includes a communication means 7 capable of communicating with the outside temperature server TC, and the communication means 7 acquires the daily average temperature from the outside temperature server TC. Therefore, the lighting power consumption can be calculated more easily.

In addition, the unit power consumption for other purposes includes the unit power consumption for electric hot water supply (unit power consumption for hot water supply), which is the power consumption of the heater-type water heater (electric water heater) in the unit period.

Therefore, with a relatively simple calculation, the hot water supply power consumption during the target period reflects the area to which the target household belongs and seasonal factors (such as the longer operating hours of electric water heaters in winter than in summer). calculated accurately. In addition, the cooling/heating power consumption is calculated with the hot/hot water supply power consumption, which fluctuates seasonally, removed, so that the cooling/heating power consumption can be calculated more accurately.

In addition, the storage means 6 stores the tilt angle, azimuth angle, system capacity and loss coefficient of the photovoltaic power generation panel provided by the target household, and the slope insolation at the tilt angle and azimuth angle in the area to which the target household belongs for each unit period. amount of solar radiation, and a unit surplus power amount, which is the amount of surplus power from the photovoltaic power generation panel for each unit period, are stored. It is calculated by subtracting the unit surplus power amount from the unit generated power amount obtained by multiplying the power generation rate obtained by dividing the solar radiation amount by the global solar radiation amount by the global solar radiation amount, the loss factor, and the system capacity. Therefore, even if the target household is equipped with solar power generation panels (solar power generation equipment), the total consumption will depend on the region to which the target household belongs and seasonal factors (slope solar radiation and global solar radiation). Electric energy can be accurately and easily grasped, and used for application decomposition.
Further, the power consumption application decomposition system D1 includes a communication means 7 capable of communicating with the solar radiation server SC, and the communication means 7 acquires global solar radiation from the solar radiation server SC.
