  “Electric energy” as used herein includes both electric energy supplied from an electric power company to a consumer facility and consumed at the consumer facility, and electrical energy generated by a power generation device or the like at the consumer facility. . That is, the usage status of electric energy includes not only the amount of power consumed at the customer facility but also the amount of power generated at the customer facility. The term “customer facility” as used herein means a facility of a consumer of energy (here, electric energy), not only a facility that receives power supply from an electric power company such as an electric power company, but also solar power. This includes facilities that receive power supply from private power generation facilities such as power generation facilities. In the present embodiment, a detached house including a photovoltaic power generation facility 91 (see FIG. 2), a fuel cell 92 (see FIG. 2), and a power storage device 93 (see FIG. 2) as a power generation device (private power generation facility) is a customer facility. An example will be described.

  As shown in FIG. 2, the display control system 10 according to the present embodiment includes information terminals 1 </ b> A, 1 </ b> B, 1 </ b> C, a controller 2, and a server device 3. The information terminals 1A, 1B, 1C, the controller 2, and the server device 3 are connected via a network 4. The controller 2 is installed in the customer facility 5.

  A measurement system 20 is connected to the controller 2. The measurement system 20 is a system that measures data related to electrical energy in the customer facility 5, and measures at least the power generation amount, the power sale amount, and the power consumption amount of the customer facility 5. In the present embodiment, the measurement system 20 is a system that measures power consumption for each of a plurality of branch circuits in the customer facility 5. Furthermore, the measurement system 20 measures the power generation amount and the power sale amount for each of the plurality of power generation devices (solar power generation equipment 91, fuel cell 92, and power storage device 93) provided in the customer facility 5.

  Here, “power generation amount” means the amount of power generated at the customer facility 5. Further, the “amount of power sold” here means the amount of power that flows backward from the customer facility 5 to the system power supply 9. Therefore, the amount of power sold includes not only the amount of power purchased by an electric power company or the like, but also the amount of power converted into points and the amount of power used for interchange of power between different customer facilities, for example.

  The information terminals 1A, 1B, and 1C are registered in association with the customer facility 5 in the display control system 10. The information terminals 1A, 1B, and 1C registered in association with one customer facility 5 may be one or a plurality of information terminals. In the example of FIG. 2, an information terminal 1 </ b> A composed of a dedicated monitor used in the consumer facility 5, an information terminal 1 </ b> B composed of a smartphone in the consumer facility 5, and an information terminal composed of a smartphone outside the consumer facility 5. Three units of 1C are used as information terminals. Hereinafter, when these three information terminals 1A, 1B, and 1C are not particularly distinguished, each is referred to as “information terminal 1”. In the present embodiment, description will be made assuming that the owner of the information terminal 1 is a user of the customer facility 5. The “user of the customer facility 5” here means a person who uses the customer facility 5, and is a resident of the customer facility 5 in the present embodiment in which the customer facility 5 is a house. When there are a plurality of residents of the customer facility 5, the “user of the customer facility 5” may refer to one of a plurality of residents, or two or more (including all). There is also. Hereinafter, “user of customer facility 5” is also simply referred to as “resident”.

  Here, the server device 3 includes a display control unit 31 (see FIG. 3) that causes the information terminal 1 to display a monitoring screen related to the usage status of electric energy in the customer facility 5. The display control unit 31 generates a monitoring screen and displays the monitoring screen on the information terminal 1 by, for example, distributing the monitoring screen to the information terminal 1 via the network 4. The information terminal 1 has at least a display unit 11. The information terminal 1 displays a monitoring screen distributed from the server device 3 on the display unit 11. In the present embodiment, as an example, the display control unit 31 generates a monitoring screen based on the measurement value of the measurement system 20.

  Thereby, the display control system 10 of this embodiment can show the monitoring screen regarding the usage condition of the electrical energy in the customer facility 5 to the owner of the information terminal 1. That is, the owner of the information terminal 1 visually uses the electric energy at the customer facility 5 by looking at the screen displayed on the display unit 11 as a customer who receives the service provided by the display control system 10. You can check the situation.

  The customer who receives the service provided by the display control system 10 (the owner of the information terminal 1) may be the same person as the resident (user of the customer facility 5), or a relative living away from the resident, for example. The resident may be a different person.

  In practice, the display control system 10 manages a plurality of customer facilities 5, and a plurality of controllers 2 are installed in the plurality of customer facilities 5, respectively. The plurality of controllers 2 are connected to the server device 3 via the network 4. In the server device 3, for example, a plurality of customer facilities 5 are distinguished by customer identifiers (customer IDs), and for each customer facility 5, generation of a monitoring screen regarding the use status of electric energy, distribution of the monitoring screen, and the like I do. However, in this embodiment, in order to simplify the description, it is assumed that the management target of the display control system 10 is one customer facility 5.

(2) Details (2.1) Measurement System First, the configuration of the measurement system 20 that is connected to the display control system 10 according to the present embodiment and measures the power generation amount, the power sale amount, and the power consumption amount in the customer facility 5. This will be described with reference to FIG.

  The measurement system 20 includes a measurement unit 21, a communication adapter 22, and current sensors 24 and 25. The measurement unit 21, the communication adapter 22, and the current sensors 24 and 25 are arranged in the cabinet of the distribution board 6. The distribution board 6 includes a main breaker 61 electrically connected to the system power supply 9 and a plurality of branch breakers 62 electrically connected to the secondary side of the main breaker 61 in the cabinet.

  The measurement unit 21 is electrically connected to the current sensors 24 and 25. The current sensor 24 is provided on the primary side of the main breaker 61 and measures the value of the current flowing through the main line. The current sensor 25 is provided corresponding to the plurality of branch breakers 62 and measures the value of the current flowing through the plurality of branch circuits. Here, the “branch circuit” means each circuit branched from the main line by a plurality of branch breakers 62. The “branch circuit” includes wiring connected to the branch breaker 62, an electric device 50 provided in the customer facility 5 and consuming electric energy (electric power), an outlet (outlet), a wall switch, and the like. The electric device 50 is, for example, an air conditioner, a washing machine, a lighting fixture, a dishwasher, a water heater, or a cooking appliance. Such a branch circuit is provided for each room such as a living room, a bedroom, an entrance, a toilet, a child's room, a kitchen, etc., or for each electric device 50 in the customer facility 5 that is a house as in the present embodiment.

  The measurement unit 21 measures the power consumption for each of the main line and the plurality of branch circuits using the outputs of the current sensors 24 and 25. The communication adapter 22 transmits the power consumption measured by the measurement unit 21 to the controller 2.

  In short, the power consumption measured by the measurement system 20 includes the power consumption measured by the measurement unit 21 for each of the trunk line and the plurality of branch circuits in the customer facility 5. The power consumption of the main line corresponds to the total power consumption of the customer facility 5 as a whole. In the present embodiment, as an example, the power consumption measured by the measurement system 20 is the power consumption obtained by integrating the power consumption of the trunk line for a certain time (for example, 1 minute).

  The measurement unit 21 is connected to a plurality of power generation devices provided in the customer facility 5, that is, a solar power generation equipment 91, a fuel cell 92, and a power storage device 93. The measurement unit 21 measures the power generation amount for each of the solar power generation equipment 91, the fuel cell 92, and the power storage device 93. Furthermore, the measurement unit 21 also measures the amount of power sold by each of the photovoltaic power generation equipment 91, the fuel cell 92, and the power storage device 93. In the present embodiment, it is assumed that power sale is permitted only for the solar power generation equipment 91 among the solar power generation equipment 91, the fuel cell 92, and the power storage device 93. Therefore, the measurement unit 21 measures only the photovoltaic power generation equipment 91 among the photovoltaic power generation equipment 91, the fuel cell 92, and the power storage device 93 with respect to the power sale amount.

  Here, regarding the power storage device 93, the amount of power discharged from the power storage device 93, that is, the amount of power discharged from the power storage device 93 corresponds to the power generation amount. Therefore, the power generation amount of the customer facility 5 measured by the measurement system 20 includes the discharge power amount of the power storage device 93. On the other hand, the amount of power used for charging the power storage device 93, that is, the amount of power charged for the power storage device 93 corresponds to the amount of power consumption. Therefore, the power consumption amount of the customer facility 5 measured by the measurement system 20 includes the discharge power amount of the power storage device 93.

  The power generation amount and the power sale amount measured by the measurement unit 21 are transmitted to the controller 2 via the communication adapter 22 in the same manner as the power consumption amount.

(2.2) Display Control System Next, the configuration of the display control system 10 according to the present embodiment will be described with reference to FIGS. 2 and 3. As described above, the display control system 10 includes the information terminal 1, the controller 2, and the server device 3. The information terminal 1, the controller 2, and the server device 3 are connected via a network 4 made of the Internet, for example.

  As illustrated in FIG. 3, the information terminal 1 includes a display unit 11, an input unit 12, a communication unit 13, and a control unit 14. The information terminal 1 is mainly composed of a computer having a CPU (Central Processing Unit) and a memory. The information terminal 1 functions as a browser that displays at least content provided from the server device 3 by installing dedicated application software and starting the application software.

  In the example of FIG. 2, as described above, the information terminal 1A is a dedicated monitor used in the customer facility 5, the information terminal 1B is a smartphone in the customer facility 5, and the information terminal 1C is the customer. It is a smartphone outside the facility 5. The information terminal 1A is a dedicated monitor compatible with HEMS (Home Energy Management System).

  The input unit 12 has a function of accepting an operation of a customer (owner of the information terminal 1). In the present embodiment, the information terminal 1 is equipped with a touch panel display, and the touch panel display functions as the display unit 11 and the input unit 12. Therefore, in the following description, various touch operations on icons on the screen displayed on the display unit 11 are expressed as “tap”, “swipe”, “drag”, and the like. However, the input unit 12 is not limited to the touch panel display, and may be a keyboard, a pointing device, a mechanical switch, or the like.

  The communication unit 13 is connected to the network 4 to enable communication between the information terminal 1 and the server device 3. Here, since the information terminal 1 </ b> A is a dedicated monitor in the customer facility 5, it is connected to the router 7 with a LAN cable. Since the information terminal 1 </ b> B is a smartphone in the customer facility 5, the information terminal 1 </ b> B performs short-range wireless communication with the router 7 in accordance with, for example, Wi-Fi (registered trademark). Since the router 7 is connected to the network 4, the information terminals 1 </ b> A and 1 </ b> B are also connected to the network 4 via the router 7. Since the information terminal 1 </ b> C is a smartphone outside the customer facility 5, the communication unit 13 is connected to the network 4 via a mobile phone network (carrier network) provided by a communication carrier. Examples of the mobile phone network include a 3G (third generation) line and an LTE (Long Term Evolution) line. The communication unit 13 may be connected to the network 4 via a public wireless LAN (Local Area Network).

  The control unit 14 controls each of the display unit 11, the input unit 12, and the communication unit 13.

  The controller 2 is installed in the customer facility 5 as shown in FIG. The controller 2 communicates with the communication adapter 22 of the measurement system 20 and acquires a measurement value (energy consumption amount) of the measurement system 20. Further, the controller 2 is a so-called HEMS controller, and communicates with each of the HEMS-compliant electrical devices 50 installed in the customer facility 5 to monitor or control the operating state of these electrical devices 50. The controller 2 is connected to the network 4 via the router 7. Thereby, the controller 2 transmits the measurement value of the measurement system 20 to the information terminal 1 and the server device 3 via the network 4 or receives the control command from the information terminal 1 and the server device 3 to change the electrical device 50. And can be controlled.

  In addition, the information terminals 1A and 1B are connected to the router 7 as described above. Therefore, the controller 2 can display the measurement value of the measurement system 20 on the information terminals 1A and 1B, and can control the electric device 50 by receiving a control command of the information terminals 1A and 1B. The information terminal 1 </ b> A may be configured to be able to communicate directly with the controller 2 without going through the router 7. The communication method of the information terminal 1A is not limited to wired communication, but may be wireless communication such as Wi-Fi (registered trademark) or low power wireless (specific low power wireless) that does not require a license. For this type of low-power radio, specifications such as the frequency band to be used and the antenna power are defined in each country depending on the application. In Japan, low-power radio that uses radio waves in the 920 MHz band or 420 MHz band is defined.

  As shown in FIG. 3, the server device 3 includes a display control unit 31, a storage unit 32, and a communication unit 33. The server apparatus 3 is mainly composed of a computer having a CPU and a memory. The server device 3 realizes a function as the display control unit 31 by executing a program recorded in the memory of the computer by the CPU. The program may be recorded in advance in the memory of the computer, but is not limited to this example, and may be provided through an electric communication line or may be provided by being recorded on a recording medium such as a memory card.

  In the storage unit 32, a customer identifier (customer ID) for identifying the customer facility 5, and identification information (address, etc.) of the information terminal 1 registered in association with the customer facility 5 and the controller 2 are registered. ) Is stored. Further, the storage unit 32 stores the power generation amount, the power sale amount, and the power consumption amount for each customer facility 5. The storage unit 32 accumulates the amount of power generation, the amount of power sold, and the amount of power consumption for a certain period (for example, for one year to several years).

  The communication unit 33 enables communication between the information terminal 1 and the controller 2 and the server device 3 by being connected to the network 4. For example, the server device 3 periodically acquires the measurement value of the measurement system 20 from the controller 2 by communicating with the controller 2 in the communication unit 33. The server device 3 stores the power generation amount, the power sale amount, and the power consumption amount in the customer facility 5 in the storage unit 32 based on the measurement values of the measurement system 20 acquired in this way. Further, the server device 3 communicates with the information terminal 1 through the communication unit 33, so that, for example, the monitoring screen generated by the display control unit 31 is transmitted to the information terminal 1 and displayed.

  The display control unit 31 causes the display unit 11 of the information terminal 1 to display a monitoring screen related to the usage status of the electric energy in the customer facility 5. Details will be described in “(2.3) Operation of display control system”, but the monitoring screen is a screen including at least both self-consumption rate information and self-sufficiency rate information, or self-consumption rate information and self-sufficiency rate. It is a screen including guide information for displaying one of the information and the other on the display unit 11.

  The “self-consumption rate information” here refers to the ratio of the self-consumption amount consisting of the difference between the power generation amount and the power sale amount of the customer facility 5 to the power consumption amount of the customer facility 5 (“self-consumption”). Rate "). In other words, the self-consumption rate information represents the ratio of the self-consumption amount to the power consumption amount of the consumer facility 5 when the difference value between the power generation amount and the power sale amount of the consumer facility 5 is defined as the self-consumption amount. The “self-sufficiency rate information” is information representing the ratio of the power generation amount of the customer facility 5 to the power consumption amount of the customer facility 5 (referred to as “self-sufficiency rate”) in the target period. In other words, the self-sufficiency rate information represents the ratio of the power generation amount of the customer facility 5 to the power consumption amount of the customer facility 5. The “target period” is a period for monitoring the usage status of the electric energy in the customer facility 5 on the monitoring screen. The length of the target period is not constant and is preferably adjustable, for example, the current day, the current month, or one year.

  The display control unit 31 uses the power generation amount, the power sale amount, and the power consumption amount in the storage unit 32 to use the personal consumption amount (power generation amount−the power sale amount) and the ratio of the private consumption amount to the power consumption amount (the private consumption amount / Power consumption) and the ratio of the power generation amount of the customer facility 5 to the power consumption (power generation amount / power consumption amount). From the value thus obtained, the display control unit 31 generates a monitoring screen including at least both the self-consumption rate information and the self-sufficiency rate information. Alternatively, the display control unit 31 generates a monitoring screen including at least one of the self-consumption rate information and the self-sufficiency rate information and guide information for causing the display unit 11 to display the other. The difference between the self-consumption rate and the self-sufficiency rate is whether the amount of power sales is excluded (self-consumption rate) or the amount of power sales is included (self-sufficiency rate) in the value compared with the amount of power consumption. Therefore, if the amount of electricity sold at the customer facility 5 in the target period is zero (0), the self-consumption rate and the self-sufficiency rate are the same. Moreover, the self-consumption rate becomes smaller as compared with the self-sufficiency rate as the amount of power sold at the customer facility 5 in the target period increases.

  In the present embodiment, since the information terminal 1 functions as a browser, the display control unit 31 generates a monitoring screen (content), outputs the generated monitoring screen to the communication unit 33, and the information terminal via the network 4. 1 to send. As a result, a monitoring screen is displayed on the display unit 11 of the information terminal 1. The display control unit 31 sends a push notification to the information terminal 1 at an appropriately set notification timing and outputs a monitoring screen. Furthermore, not only the notification timing, but if there is a request from the information terminal 1, the display control unit 31 outputs a monitoring screen as needed. A specific example of the monitoring screen will be described in the column “(2.3) Operation of display control system”.

(2.3) Operation of Display Control System Next, the operation of the display control system according to the present embodiment will be described with reference to FIG.

  FIG. 1 shows a specific example of a monitoring screen 100 displayed on the display unit 11 of the information terminal 1. The monitoring screen 100 shown in FIG. 1 is a screen that includes both the self-consumption rate information 108 and the self-sufficiency rate information 104. That is, here, a case where the display control unit 31 displays a screen including both the self-consumption rate information 108 and the self-sufficiency rate information 104 as the monitoring screen 100 on the display unit 11 is illustrated. Here, the operation of the display control system 10 at 12 o'clock on December 15, 2016 is illustrated. In FIG. 1, the alternate long and short dash line and the reference symbol indicating the region are merely shown for explanation, and actually, the alternate long and short dash line and the reference symbol are not displayed on the display unit 11 of the information terminal 1.

  In the example of FIG. 1, a screen displayed on the information terminal 1 </ b> A in which the display area of the display unit 11 is horizontally long is assumed. Therefore, the monitoring screen 100 is displayed sideways so that the longitudinal direction of the display area of the display unit 11 is horizontal. That is, the monitoring screen 100 is a horizontally long screen.

  As a basic operation, the information terminal 1 displays the monitoring screen 100 on the display unit 11 when an operation for selecting the self-activity rate mode is performed on the home screen displayed on the display unit 11 when the application software is started. Display (display step). Since the monitoring screen 100 is a screen (content) distributed from the server device 3, the monitoring screen 100 can be displayed only when the information terminal 1 can communicate with the server device 3.

  The monitoring screen 100 shown in FIG. 1 roughly includes two areas, a first area 101 and a second area 102. The first area 101 is displayed on the left side of the second area 102 on the monitoring screen 100. In the first area 101, information related to the self-sufficiency rate is displayed, and in the second area 102, information related to the self-consumption rate is displayed. Further, period selection tabs 103A, 103B, and 103C for selecting a target period are displayed on the left side of the first area 101 on the monitoring screen 100. FIG. 1 illustrates a case where the period selection tab 103A written as “today” is selected and today (the current day) is designated as the target period.

  Specifically, in the first area 101, self-sufficiency rate information 104, explanation information 105, self-sufficiency rate graph 106, and detailed information 107A and 107B are displayed.

  The self-sufficiency rate information 104 is information representing, as a “self-sufficiency rate”, the ratio of the power generation amount of the customer facility 5 to the power consumption amount (power generation amount / power consumption amount) as a percentage. In the example of FIG. 1, the self-sufficiency rate information 104 is “80%”, and represents that the power generation amount of the customer facility 5 in the target period corresponds to 80% of the power consumption amount. The explanation information 105 is information explaining the self-sufficiency rate, and is displayed below the self-sufficiency rate information 104. In the example of FIG. 1, the explanation information 105 is made up of text “The self-sufficiency rate is the ratio of power generation to the amount of power used.

  The self-sufficiency rate graph 106 is an object (graph) that supplements the self-sufficiency rate, and is displayed below the description information 105. The self-sufficiency rate graph 106 includes consumption information G1 representing the power consumption amount of the customer facility 5 in the target period (2.5 kWh in the example of FIG. 1), and the power generation amount of the customer facility 5 in the target period (in the example of FIG. 1). 2.0 kWh) of power generation information G2. That is, the self-sufficiency rate graph 106 includes two graphs of consumption information G1 and power generation information G2. Here, the consumption information G1 and the power generation information G2 are both bar graphs extending in the vertical direction, and are arranged in the order of the consumption information G1 and the power generation information G2 from the left. The consumption information G1 and the power generation information G2 preferably have different display modes such as colors. In the example of FIG. 1, since the self-sufficiency rate is 80%, the ratio of the power generation information G2 to the consumption information G1 is 80%.

  Detailed information 107A and 107B represent consumption information G1 and power generation information G2 by numerical values, respectively. In the example of FIG. 1, the detailed information 107 </ b> A of the consumption information G <b> 1 indicates that the “power consumption” (power consumption) is “2.5 kWh”. Detailed information 107B of the power generation information G2 indicates that the “power generation amount” is “2.0 kWh”. The detailed information 107A and 107B also serves as a legend display of the self-sufficiency rate graph 106.

  On the other hand, in the second area 102, the personal consumption rate information 108, the explanation information 109, the personal consumption rate graph 110, and the detailed information 111A, 111B, 111C are displayed.

  The self-consumption rate information 108 is information representing, as a “self-consumption rate”, the ratio of the self-consumption amount (power generation amount−power sales amount) to the power consumption amount (self-consumption amount / power consumption amount) as a percentage. In the example of FIG. 1, the personal consumption rate information 108 is “70%”, indicating that the personal consumption amount of the customer facility 5 in the target period corresponds to 70% of the power consumption amount. The explanation information 109 is information explaining the self-consumption rate, and is displayed below the self-consumption rate information 108. In the example of FIG. 1, the explanation information 109 is made up of text that “the self-consumption rate is a ratio indicating how much of the generated electricity is consumed at home”.

  The self-consumption rate graph 110 is an object (graph) that supplements the self-consumption rate, and is displayed below the explanation information 109. The self-consumption rate graph 110 includes self-consumption information G3 that represents the self-consumption amount of the customer facility 5 in the target period (1.75 kWh in the example of FIG. 1), and the power purchase amount of the consumer facility 5 in the target period (of FIG. 1). In the example, it includes power purchase information G4 representing 0.75 kWh). The “power purchase amount” here is the amount of power purchased by the consumer, that is, the amount of power supplied from the system power supply 9 to the customer facility 5. In other words, the “amount of power purchased” is the amount of power that cannot be covered by the amount of power generation among the amount of power consumed, and is a difference value between the amount of power consumed and the amount of private consumption (power consumption-private consumption).

  Thus, the private consumption rate graph 110 is composed of two graphs of private consumption information G3 and electricity purchase information G4. Here, the self-consumption information G3 and the power purchase information G4 both form a single ring-shaped (doughnut-shaped) graph. That is, the self-consumption rate graph 110 is expressed by dividing one ring graph into self-consumption information G3 and power purchase information G4 in the circumferential direction. The self-consumption information G3 and the power purchase information G4 are preferably different in display mode such as color and radial width. In the example of FIG. 1, since the self-consumption rate is 70%, 70% of the ring-shaped graph is occupied by self-consumption information G3, and 30% is electricity purchase information G4.

  Furthermore, in this embodiment, the self-consumption information G3 includes self-consumption breakdown information distinguished according to the type of power generation device. Specifically, the self-consumption information G3 includes first breakdown information G31 that represents the self-consumption amount of the solar power generation equipment 91 (difference value between the power generation amount and the power sale amount) and the self-consumption amount of the fuel cell 92. 2 breakdown information G32. The first breakdown information G31 and the second breakdown information G32 constitute self-consumption breakdown information, and it is preferable that display modes such as colors are different.

  The detailed information 111A, 111B, and 111C represent the personal consumption information G3 and the power purchase information G4 as numerical values, respectively. In the example of FIG. 1, since the personal consumption information G3 includes the first breakdown information G31 and the second breakdown information G32, the detailed information 111A that represents the first breakdown information G31 in the detailed information 111A, 111B, and 111C, and the second Detailed information 111B representing the breakdown information G32 is included. Detailed information 111A of the first breakdown information G31 indicates that the amount of personal consumption of “sunlight” (solar piezoelectric equipment 91) is “1.25 kWh”. The detailed information 111B of the second breakdown information G32 represents that the self-consumption amount of “fuel cell” is “0.5 kWh”. The detailed information 111C of the power purchase information G4 indicates that the “power purchase amount” is “0.75 kWh”. The detailed information 111 </ b> A, 111 </ b> B, 111 </ b> C also serves as a legend display of the personal consumption rate graph 110.

  By the way, when the period selection tab 103B or 103C is tapped while the monitoring screen 100 as described above is displayed on the display unit 11, the length of the target period is changed (period change step). That is, when the period selection tab 103B labeled “current month” is tapped, the target period is the current month. When the period selection tab 103C labeled “Total” is tapped, the target period is the past year. When the length of the target period is changed, the display control unit 31 updates the monitoring screen 100 and distributes the updated monitoring screen 100 to the information terminal 1. Thereby, the monitoring screen 100 displayed on the display unit 11 is changed.

(3) Implementation means other than the display control system Functions equivalent to those of the display control system 10 according to this embodiment described above are not limited to the system means, and can also be realized by the following means. Even when the display control system 10 according to the present embodiment is embodied by the following units, the various configurations described above and modifications described below can be applied in appropriate combinations.

(3.1) Display Control Method The display control method according to the present embodiment includes a display step of causing the display unit 11 of the information terminal 1 to display the monitoring screen 100 related to the usage status of electric energy in the customer facility 5. In the display step, a screen including both the self-consumption rate information and the self-sufficiency rate information, or guide information for causing the display unit 11 to display one of the self-consumption rate information and the self-sufficiency rate information, and the other, Is displayed on the display unit 11 as the monitoring screen 100. The self-consumption rate information represents the ratio of the self-consumption amount, which is the difference between the power generation amount of the customer facility 5 and the power sale amount, to the power consumption amount of the customer facility 5 in the target period. The self-sufficiency rate information represents the ratio of the power generation amount of the customer facility 5 to the power consumption amount of the customer facility 5 in the target period.

  Such a display control method is realized, for example, by the CPU executing a program in the server apparatus 3 mainly including a computer.

(3.2) Display Control Program A display control program according to the present embodiment is a program for causing a computer to execute the above-described display control method.

  Such a display control program is executed by the server apparatus 3 mainly composed of a computer, for example. The display control program may be provided through an electric communication line such as the Internet or recorded on a recording medium such as a memory card, or may be recorded in advance in a memory of a computer.

(4) Effect As described above, the display control system 10 of the present embodiment includes the display control unit 31 that displays the monitoring screen 100 on the usage status of the electrical energy of the customer facility 5 on the display unit 11 of the information terminal 1. Prepare. The display control unit 31 causes the display unit 11 to display a screen including both the self-consumption rate information 108 and the self-sufficiency rate information 104, or one of the self-consumption rate information 108 and the self-sufficiency rate information 104, and the other. A screen including the guide information is displayed on the display unit 11 as the monitoring screen 100. The self-consumption rate information 108 represents the ratio of the self-consumption amount composed of the difference between the power generation amount and the power sale amount of the customer facility 5 to the power consumption amount of the customer facility 5 in the target period. The self-sufficiency rate information 104 represents a ratio of the power generation amount of the customer facility 5 to the power consumption amount of the customer facility 5 in the target period.

  According to this configuration, both the self-consumption rate and the self-sufficiency rate can be presented to the customer (customer). To aim for customer facilities 5 that have zero net primary energy consumption, such as ZEH (Net Zero Energy House) and ZEB (Net Zero Energy Building) Self-consumption of energy is desired. In particular, considering that the merit of selling electricity will fade due to, for example, the end of the preferential period of the feed-in tariff (FIT), high self-sufficiency is not enough, and the self-consumption rate is also 100%. It is desirable to be close to If the electric power generated at the customer facility 5 can cover all of the electric energy consumed at the customer facility 5 (self-consumed), the customer (customer) can obtain environmental and economic benefits. growing. Therefore, customers (customers) are required to perform energy saving activities different from mere power saving by increasing both the self-consumption rate and the self-sufficiency rate by introducing, for example, a fuel cell 92 and a power storage device 93. Since both the self-sufficiency rate and the self-consumption rate information can be obtained from the monitoring screen 100, there is an advantage that it is easy to obtain an effect of promoting self-consumption of electric energy in the customer facility 5. The display control method and the display control program described in the section “(3) Implementation means other than display control system” have the same advantages.

  Further, as in the present embodiment, the power storage device 93 is provided in the customer facility 5, and the power consumption amount of the consumer facility 5 includes the amount of electric power charged in the power storage device 93. It is preferable that the amount of generated power includes the amount of electric power discharged from the power storage device 93. According to this aspect, by using the power storage device 93, it is possible to reduce the amount of power sales and increase the self-consumption rate in the target period. However, this aspect is not essential for the display control method according to the present embodiment, and the power storage device 93 may not be provided in the customer facility 5.

  Further, as in the present embodiment, the monitoring screen 100 includes consumption information G1 indicating the power consumption amount of the customer facility 5 in the target period and power generation information G2 indicating the power generation amount of the customer facility 5 in the target period. It is preferable to further include. According to this aspect, not only the self-sufficiency rate information 104 but also information representing each of the power consumption amount and the power generation amount of the customer facility 5 in the target period is displayed on the monitoring screen 100. Therefore, the customer can individually recognize the amount of power consumption and the amount of power generation that determine the self-sufficiency rate.For example, take specific measures such as how much power consumption should be reduced to increase the self-sufficiency rate. Easy to stand. However, this aspect is not essential for the display control method according to the present embodiment, and the monitoring screen 100 may not include the consumption information G1 and the power generation information G2.

  Further, as in the present embodiment, the monitoring screen 100 includes self-consumption information G3 that represents the amount of personal consumption of the customer facility 5 in the target period, and power purchase information G4 that represents the amount of power purchased by the customer facility 5 in the target period. It is preferable that these are further included. According to this aspect, on the monitoring screen 100, not only the self-consumption rate information 108 but also the self-consumption amount (power generation amount-power sales amount) and the power purchase amount (power consumption amount-self-consumption amount) of the customer facility 5 in the target period. ) Is displayed. Therefore, the customer can individually recognize the amount of self-consumption and the amount of power purchased (power consumption) that determine the self-consumption rate. For example, how much power consumption should be reduced to increase the self-consumption rate? It becomes easy to take concrete measures. However, this aspect is not essential for the display control method according to the present embodiment, and the personal consumption information G3 and the power purchase information G4 may not be included in the monitoring screen 100.

  In this case, as in the present embodiment, the self-consumption information G3 preferably includes self-consumption breakdown information (first breakdown information G31 and second breakdown information G32) distinguished according to the type of power generation device. According to this aspect, for example, when a plurality of types of power generation devices such as the solar power generation equipment 91, the fuel cell 92, and the power storage device 93 are provided in the customer facility 5, the plurality of types of power generation devices are displayed on the monitoring screen 100. Information representing the individual consumption of each is displayed. Therefore, the customer can recognize the self-consumption amount for which the self-consumption rate is determined for each power generation device. For example, what kind of power generation device should be added in order to increase the self-consumption rate. It becomes easy to take appropriate measures. However, this aspect is not essential for the display control method according to the present embodiment, and the self-consumption information G3 may be displayed without distinction depending on the type of power generation device, similar to the power generation information G2 shown in FIG.

  Further, as in the present embodiment, the display control method preferably further includes a period changing step for changing the length of the target period. That is, for example, when one of the period selection tabs 103A, 103B, and 103C is selected, the length of the target period is changed. According to this aspect, the customer can check both the self-consumption rate and the self-sufficiency rate while changing the length of the target period. However, this aspect is not essential for the display control method according to the present embodiment, and the length of the target period may be constant.

(5) Modification The configuration described in the first embodiment is merely an example of the present invention, and the present invention is not limited to the first embodiment. The technical idea according to the present invention can be applied to other configurations than the first embodiment. Various changes can be made according to the design or the like as long as they do not deviate. Hereinafter, modifications of the first embodiment will be listed.

(5.1) Modification 1
In FIG. 1, the case where the monitoring screen 100 is a screen including both the self-consumption rate information 108 and the self-sufficiency rate information 104 is illustrated, but the monitoring screen is one of the self-consumption rate information and the self-sufficiency rate information, A screen including guide information for displaying the other on the display unit 11 may be used. That is, in the first modification, the display control unit 31 monitors a screen including both the self-consumption rate information and the self-sufficiency rate information, and the guide information (for displaying the other on the display unit 11). It is displayed on the display unit 11 as a screen. Thereby, in the modification 1, only one of the self-consumption rate information and the self-sufficiency rate information is displayed on the monitoring screen, and information that is not included in the monitoring screen among the self-consumption rate information and the self-sufficiency rate information is monitored. It can be displayed according to the guide information on the screen. Specifically, the monitoring screen is composed of a screen including both self-consumption rate information and guide information for displaying the self-sufficiency rate information on the display unit 11 (hereinafter referred to as “self-consumption rate priority screen”). . Alternatively, the monitoring screen includes a screen including both self-sufficiency rate information and guide information for displaying the self-consumption rate information on the display unit 11 (hereinafter referred to as “self-sufficiency priority screen”).

  When the monitoring screen is a self-consumption rate priority screen, the guide information is information for displaying the self-sufficiency rate information on the display unit 11, for example, a self-sufficiency rate with a link to a screen including the self-sufficiency rate information. Consists of link information. The self-sufficiency rate link information is composed of text such as “here is self-sufficiency rate”, which suggests the display of self-sufficiency rate information. In this case, when the self-sufficiency rate link information is tapped on the monitoring screen, a screen including the self-sufficiency rate information is displayed on the display unit 11. The screen including the self-sufficiency rate information may be displayed as a pop-up on the monitoring screen, or may be switched from the monitoring screen to a screen including the self-sufficiency rate information.

  When the monitoring screen is a self-sufficiency rate priority screen, the guide information is information for causing the display unit 11 to display the self-consumption rate information. For example, the home information on which a link to a screen including self-consumption rate information is pasted Consists of consumption rate link information. The self-consumption rate link information includes, for example, text such as “here is the self-consumption rate” that suggests display of the self-consumption rate information. In this case, when the personal consumption rate link information is tapped on the monitoring screen, a screen including the personal consumption rate information is displayed on the display unit 11. The screen including the personal consumption rate information may be displayed as a pop-up on the monitoring screen, or may be switched from the monitoring screen to a screen including the personal consumption rate information.

  Furthermore, guide information should just be the information for making the display part 11 display the information which is not contained in the monitoring screen among self-consumption rate information and self-sufficiency rate information, and link information (self-sufficiency rate link information or self-consumption rate link) Information). For example, when the monitoring screen is a self-consumption rate priority screen, the screen displayed on the display unit 11 may be switched from the monitoring screen to a screen including self-sufficiency rate information by a swipe operation on the monitoring screen. In this case, the guide information includes, for example, text such as “Swipe the screen to the right to check the self-sufficiency rate” suggesting a swipe operation, or an icon suggesting the swipe operation. Similarly, when the monitoring screen is the self-sufficiency rate priority screen, the screen displayed on the display unit 11 may be switched from the monitoring screen to a screen including self-consumption rate information by a swipe operation on the monitoring screen. In this case, the guide information includes, for example, text such as “Swipe the screen to the right to check the self-consumption rate” suggesting a swipe operation, or an icon suggesting the swipe operation.

  Also in the modification 1, since the information of both the self-sufficiency rate and the self-consumption rate can be obtained from the monitoring screen as in the first embodiment, the effect of promoting the self-consumption of electric energy in the customer facility 5 is obtained. There is an advantage that it is easy. Furthermore, in the first modification, the self-consumption rate information and the self-sufficiency rate information are individually displayed, so that it is possible to secure a large display area on the display unit 11.

(5.2) Other Modifications In the first embodiment, a detached house is described as an example of a customer facility. However, the present invention is not limited to this example, and the customer facility is a detached house such as each dwelling unit of an apartment house. It may be a house other than a house, or a non-house such as an office or a store.

  The information terminal 1 is not limited to a dedicated monitor and a smartphone, but may be an information terminal that can be connected to a network 4 such as a portable information terminal such as a tablet terminal, a personal computer, or a smart TV. Furthermore, although the monitoring screen 100 displayed on the information terminal 1A is illustrated in FIG. 1, the same monitoring screen 100 may be displayed on the other information terminals 1B and 1C.

  The controller 2 may be configured to be able to communicate with a smart meter installed in the customer facility 5. In this case, at least one of the power generation amount, the power sale amount, and the power consumption amount of the customer facility 5 used in the display control system 10 is not the measurement value of the measurement system 20 but the measurement value of the smart meter. Good.

  Further, the display control unit 31 is provided in the server device 3 in the first embodiment. However, the display control unit 31 is not limited to this configuration. For example, the display control unit 31 is distributed to two or more of the information terminal 1, the controller 2, and the server device 3. May be provided. The display control unit 31 may be provided in the controller 2 or the information terminal 1 instead of the server device 3. In this case, even if the server device 3 is omitted, the monitoring screen 100 is generated by the controller 2 or the information terminal 1. Further, the display control unit 31 may be provided in each of the server device 3 and the controller 2. In this case, which of the server apparatus 3 and the controller 2 generates the monitoring screen 100 may be determined depending on the distribution destination of the monitoring screen 100 (any one of the information terminals 1A, 1B, and 1C). As an example, if the distribution destination of the monitoring screen 100 is the information terminal 1A or 1B, the controller 2 generates the monitoring screen 100. If the distribution destination of the monitoring screen 100 is the information terminal 1C, the server device 3 displays the monitoring screen 100. Is generated.

  Furthermore, the display control system 10 does not necessarily include the information terminal 1, the controller 2, and the server device 3. For example, the display control system 10 includes at least one of the information terminal 1, the controller 2, and the server device 3. May be. At least some of the functions of the display control system 10 may be realized by, for example, cloud (cloud computing).

  Further, the measurement system 20 is not limited to the configuration in which the measurement unit 21 is provided in the cabinet of the distribution board 6 as in the first embodiment.

Furthermore, the measurement system 20 may be configured such that a measurement device is built in an outlet (outlet) included in the branch circuit, or a measurement device is connected between an outlet and an electrical device.

  Further, the screen configuration and content of the monitoring screen 100 are not limited to the screen configuration and content illustrated in the first embodiment, and can be changed as appropriate. For example, in the monitoring screen 100, the self-consumption rate information 108 and the self-sufficiency rate information 104 are not limited to numerical values, and may be represented by an animation using a character. In this case, for example, the self-sufficiency rate and the self-consumption rate are expressed by changing the state of the character (such as a facial expression). As for the self-sufficiency rate information 104, if the self-sufficiency rate is 10% to 60%, the image is “normal”. If the self-sufficiency rate exceeds 60%, the image is “good.” The self-sufficiency rate is less than 10% to 60%. The character changes so that the image becomes “bad”.

  Moreover, when the output suppression in which the reverse power flow from the power generation device of the customer facility 5 to the system power supply 9 is restricted by an electric power company or the like is performed, the monitoring screen 100 displays the self-consumption amount of the power generation amount. Of these, the amount of power used without being affected by output suppression may be displayed. Thereby, the amount of electric power obtained without being affected by the output suppression can be presented to the customer.
