Also good.

  FIG. 1 is a diagram showing a system and equipment installed in the facility 1. FIG. 2 is a block diagram illustrating configurations of the information display system 10 and the output control system 40 which are an example of the embodiment. As illustrated in FIGS. 1 and 2, the information display system 10 includes an information terminal 11 including a display unit 12 that displays information related to the grid-connected power supply system 2, and a control device 16. The control device 16 has a function of causing the display unit 12 to display a first screen including information on an output control period, which is a period in which output control of the power supply system 2 based on power supply and demand prediction of the power provider is executed.

  In addition, the control device 16 causes the first screen to display at least one of the power generation amount and the power sale amount of the power supply system 2 in the first period and the output control period in the first period on the same time axis. In this specification, the power generation amount of the power supply system 2 includes not only the integrated value of the power generated during a predetermined period but also instantaneous generated power. Similarly, the amount of power sold by the power supply system 2 includes not only an integrated value of power sold during a predetermined period but also instantaneous power sold.

  The information display system 10 is a preferred example of a system for realizing an information display method for displaying an output control period of the power supply system 2 executed at the request of the power provider on the display unit 12. According to the information display system 10, the power generation company can easily check the output control period. In this specification, a power generation company means a person who sells power to a power company using the power supply system 2 and includes an individual who owns a household power generation facility. The power supply system 2 is a system that supplies power to the power system.

  In the example shown in FIG. 1, an information display system 10 is installed in a facility 1 (a detached house) where a power supply system 2 is installed. However, the information display system 10 may not be installed in the facility 1. The information display system 10 may be installed in a different place from the facility 1 and may be configured by a mobile terminal such as a notebook computer, a tablet terminal, or a smartphone.

  The facility 1 is provided with a watt hour meter to which a trunk line (primary trunk line) of an AC power source is connected, and a distribution board 20 that branches the secondary trunk line from the watt hour meter. In the example shown in FIG. 1, as a watt hour meter, a power purchase meter 21 that measures the power consumption and power consumption of the facility 1 and the power supply system 2 supply the system (hereinafter sometimes referred to as “reverse power flow”). And a power sale meter 22 for measuring the electric power and the electric energy. The two meters may be integrated. The watt hour meter has a communication function, for example, and the information display system 10 may acquire measurement data to be displayed on the display unit 12 of the information terminal 11 from the watt hour meter.

  The facility 1 is provided with a television 23, a refrigerator 24, an air conditioner 25, an IH cooking heater 26, an illumination 27, and the like as electric devices that use electric power. The electric equipment used in the facility 1 is not limited to these, and examples include a microwave oven, a personal computer, a washing machine, a dryer, and floor heating.

  In the facility 1, a solar power generation device 30 and a fuel cell device 32 are installed as a grid-connected power supply system 2. The power supply system 2 is not limited to these. In addition, a power storage device 34 is installed in the facility 1. In the present embodiment, power is generated by the solar power generation device 30 and the fuel cell device 32, and the remaining electric power that is not used in the electrical equipment is charged to the power storage device 34 and supplied to the system. The electric power charged in the power storage device 34 is used, for example, at night when the solar power generation device 30 does not generate power. The total amount of power generated by the solar power generation device 30 may be supplied to the system, and in some cases, the power stored in the power storage device 34 may be supplied to the system.

  The solar power generation device 30 is a power generation facility that includes a plurality of solar cell modules and generates power by receiving sunlight in the daytime when sunlight is irradiated. The solar power generation device 30 is installed on the roof of the facility 1, for example. In general, a power conditioner 31 (hereinafter referred to as “power converter 31”) is connected to the photovoltaic power generation apparatus 30, and DC power generated by the photovoltaic power generation apparatus 30 by the power conditioner 31 is converted into AC power. . The power conditioner 31 has a function of controlling the output of the solar power generation device 30 and controlling the effective power supplied to the system.

  The fuel cell device 32 is a power generation facility that generates power by reacting hydrogen extracted from gas with oxygen in the air, and can generate power for 24 hours. It is preferable that the fuel cell device 32 also has a function of a water heater that boils hot water using heat generated during power generation. A power conditioner 33 (hereinafter referred to as “power converter 33”) is connected to the fuel cell device 32, and the DC power generated by the fuel cell device 32 by the power converter 33 is converted into AC power. In the fuel cell device 32, the active power supplied to the system by the power conditioner 33 may be controlled, but the power generation amount is preferably controlled by changing the operating state of the fuel cell device 32.

  The power storage device 34 is a device for storing the electric power generated by the solar power generation device 30 and is formed of a secondary battery that can be repeatedly charged and discharged. The electric power converted from direct current to alternating current by the power conditioner 31 is converted again to direct current by the power conditioner 35 (hereinafter referred to as “power conditioner 35”) and stored in the power storage device 34. In the example shown in FIG. 1, the power conditioners 31 and 35 are provided, but they can be integrated.

  The active power supplied to the system from the power supply system 2 is controlled based on, for example, an output control schedule. The output control schedule is an output control plan provided by an electric power company in order to realize stable power supply by controlling the output of the power supply system 2. In the present embodiment, an output control system 40 that controls the output of the power supply system 2 based on the output control schedule is installed in the facility 1.

  The output control system 40 includes an acquisition unit 41 that acquires output control schedule information, a storage unit 42 that stores the schedule information, and an output unit 43 that controls the output of the power supply system 2 based on the schedule information. And have. The output control schedule includes a fixed schedule that is determined based on the power supply / demand prediction for the predetermined period A and an update schedule that is determined based on the power supply / demand prediction for the predetermined period B shorter than the predetermined period A. Here, an example of the predetermined period A is one year, and an example of the predetermined period B is one day.

  The acquisition unit 41 accesses the server 45 of the electric power company through, for example, an Internet line or a dedicated line, and acquires output control schedule information. Hereinafter, output control schedule information (including information related to the schedule) may be simply referred to as “output control schedule”. Moreover, the acquisition part 41 may acquire the output control schedule transmitted from the server 45, and may acquire the said schedule via a specific delivery provider. The acquisition unit 41 causes the storage unit 42 to store the acquired output control schedule.

  The acquisition unit 41 acquires an output control schedule at a predetermined frequency through communication with the server 45 or the like. When the output control schedule is automatically acquired by the acquisition unit 41, for example, the schedule is acquired with a frequency of about once a day. On the other hand, when the output control system 40 is not configured to communicate with the server 45, the output control schedule is manually rewritten, for example, once a year.

  In addition to the output control schedule, the storage unit 42 may store a control program for realizing the functions of the output control system 40, the amount of power generated by the power supply system 2, the amount of power sold, and the like. The storage unit 42 is configured by a non-temporary storage medium such as a computer-readable ROM, an optical disk, or a hard disk drive.

  The output unit 43 outputs a control command for suppressing the active power supplied to the system to the power conditioner 31, the fuel cell device 32, and the like based on the output control schedule, for example. The power conditioner 31 that has received such a control command may suppress the amount of power generated by the solar power generation device 30 itself, or input power (reactive power) from the system and suppress active power that is reversely flowed. Further, for example, the power generation of the fuel cell device 32 is stopped or the amount of charge of the power storage device 34 is increased by the control command of the output unit 43, so that the active power that flows backward is suppressed. The output unit 43 may transmit a signal (control command) to a relay device that relays communication with a control target device such as the power conditioner 31. Further, the communication protocol used in the output control system 40 and the information display system 10 is not particularly limited. For example, the signal of the output unit 43 may be transmitted by Echonet-lite.

  In addition, since the accuracy of power supply and demand prediction one year ahead is lower than the accuracy of the previous day's supply and demand prediction, output control of the power supply system 2 tends to increase in output control based on a fixed schedule. Therefore, the output unit 43 executes output control based on the update schedule when the update schedule is acquired, and executes output control based on the fixed schedule when the update schedule does not exist. When the output control system 40 is not in the communication environment, for example, the output of the power supply system 2 is controlled only by a fixed schedule.

  The output control system 40 further includes a time setting unit 44 that sets a time used for execution of output control based on the output control schedule. The time set by the time setting unit 44 is stored in the storage unit 42, for example. The output unit 43 outputs a control command to the power supply system 2 based on the time and the output control schedule. The time setting unit 44 acquires clock information from the server 45 or the server of the distributor through, for example, an Internet line or a dedicated line, and sets a time synchronized with the clock information. The time setting unit 44 may perform time synchronization using a global positioning system (GPS).

  The time setting unit 44 may set a time manually input by a service person as a time used for executing the output control. The time setting unit 44 may set a manually input time on condition that an authentication code is received, for example. The authentication code is a code that is input by the service person and is unknown to the power generation company. As will be described in detail later, the time setting unit 44 may have a manual time adjustment function. However, in order to prevent tampering of the clock, it is preferable to limit the change of time within a predetermined range, such as within ± 10 minutes per day.

  As described above, the information display system 10 is a system for displaying information on the grid-connected power supply system 2 on the display unit 12 of the information terminal 11 to inform the power generation company. The information display system 10 acquires information related to output control of the power supply system 2 through communication with, for example, the server 45 of the power company or the server of the distribution company. In the present embodiment, the information display system 10 acquires information related to output control including the output control schedule via the output control system 40 and displays the information on the display unit 12 of the information terminal 11.

  The information display system 10 can use information, programs, and the like stored in the storage unit 42 of the output control system 40. For example, the information display system 10 reads information including the output control schedule from the storage unit 42 and displays the information on the display unit 12. The information display system 10 may have the same function as the acquisition unit 41 and may acquire the output control schedule at a predetermined frequency through communication with the server 45 or the like.

  The information display system 10 is constructed by a computer including one or a plurality of devices including, for example, a processor (CPU), a memory, an input / output port, and the like. In the example illustrated in FIG. 1, the control device 16 is configured by the home server 15, and the information terminal 11 and the control device 16 are configured by different devices, but these may be configured by one device. That is, the information display system 10 can be composed of one or a plurality of devices. Further, the information display system 10 may be constructed by one or a plurality of servers in which a part of the system is connected by a network such as the Internet.

  The information display system 10 may be configured as a part of the output control system 40. In addition, the facility 1 may be provided with an energy management system that monitors the power consumption of the entire facility and controls each electrical device. The information display system 10 and the output control system 40 are connected to the energy management system. It may be configured as a part. Although the control device 16 and the output control system 40 of the information display system 10 may be configured by different devices, in the present embodiment, the control device 16 and the output control system 40 are configured by one home server 15. .

  The information terminal 11 is a terminal device having a display unit 12 that can display information related to the power supply system 2. A suitable display unit 12 is a display such as a liquid crystal display or an organic EL display. The information terminal 11 preferably further includes an operation unit 13 for switching the screen of the display unit 12. Examples of the operation unit 13 include a button, a numeric keypad, and a keyboard, and may be a touch panel integrated with the display unit 12.

  The information terminal 11 is a dedicated terminal installed in the facility 1, for example, but may be installed in a different place from the facility 1, and may be configured by a mobile terminal such as a laptop computer, a tablet terminal, or a smartphone. . Further, a plurality of information terminals 11 may be provided, and the information terminal 11 may be used as a terminal device for the output control system 40 and the energy management system. In the example shown in FIG. 1, the information terminal 11 and the home server 15 are configured by different devices, but they may be configured by one integrated device.

  The control device 16 causes the display unit 12 of the information terminal 11 to display information regarding the power supply system 2. The control device 16 causes the display unit 12 to display a first screen including information on an output control period that is a period during which output control of the power supply system 2 based on power supply and demand prediction of the power provider is executed. Have On the first screen, the first output unit 17 includes at least one of the power generation amount and the power sale amount of the power supply system 2 in the first period (hereinafter sometimes referred to as “power generation amount”) and the output control in the first period. The period is displayed on the same time axis. In the present embodiment, the output control period is a period during which effective power supplied to the system of the power supply system 2 is suppressed based on the output control schedule.

  The control device 16 preferably includes a second output unit 18 that causes the display unit 12 to display a second screen including information on the presence or absence of an output control period for each first period in a second period including a plurality of first periods. . Furthermore, it is preferable that the control device 16 includes a third output unit 19 that causes the display unit 12 to display a third screen including detailed information on output control in the output control period. The control device 16 may acquire information on the output control schedule from the server 45 of the electric power company and display the screens based on the information. In the present embodiment, the control device 16 stores the information in the storage unit 42 of the output control system 40. Stored power control schedule information can be used.

  The control device 16 may display the home screen on the display unit 12 of the information terminal 11. The home screen is a screen displayed when the information display system 10 is activated. Further, when the display unit 12 has not been operated for a predetermined period, when the display unit 12 has been operated after a predetermined period has not been operated, or when a reset operation has been performed, the first operation unit is displayed on the display unit 12. A home screen may be displayed as a screen (operation reception screen). The control device 16 may display the type of the output control schedule on the home screen or another screen. As the type of output control schedule, a fixed schedule and an update schedule can be exemplified as described above.

  FIG. 3 is a diagram illustrating an example of the home screen. As illustrated in FIG. 3, a wallpaper image, a menu button, and an information box are displayed on the home screen. In the example shown in FIG. 3, a house illustration is displayed as a wallpaper image, but the wallpaper image is not particularly limited. Moreover, although information on generated power and power consumption is displayed on the home screen, the displayed information is not particularly limited. Menu buttons and notification boxes are displayed at the bottom of the home screen. In the notification box, for example, information related to the facility 1 including information on the power supply system 2 may be displayed, and information distributed from the power company may be displayed.

  The menu button is an operation unit 13 for performing various settings, for example, and an input screen for receiving various setting information is displayed by operating the menu button. The menu button may be a button for switching from the home screen to another screen such as the first screen, and the power generator (hereinafter sometimes referred to as “user”) supplies power by operating this button. Various information related to the system 2 can be displayed on the display unit 12. When the information terminal 11 is also used as a terminal device such as the output control system 40 and the energy management system, the setting of the power supply system 2 can be changed by operating a menu button or the like.

  As illustrated in FIG. 3A, when the output control of the power supply system 2 based on the fixed schedule is being executed, the characters “output control in progress” are displayed on the home screen. Further, as illustrated in FIG. 3B, when output control based on the update schedule is being executed, a bar (underbar) is displayed below the characters in addition to the characters “output control is in progress”. . In this case, the type of the output control schedule that is the basis of the output control being executed can be easily confirmed by the presence or absence of the underbar.

  The “output control in progress” display on the home screen may be displayed as a button operated by the user. When a button on which “in output control” is displayed is pressed, an explanation regarding output control may be displayed in a pop-up. This button may be an operation button for switching from the home screen to the first screen.

  FIG. 4 is a diagram illustrating another example of the home screen. As illustrated in FIG. 4, the home screen displays a photovoltaic power generation device 30 that constitutes the power supply system 2, a power generation amount for each fuel cell device 32, a power generation amount on the previous day, a charging time for the power storage device 34, and the like. May be. In addition, on the home screen, the amount of power purchased, the amount of power sold, the amount of power used, the amount of hot water, water, and the amount of gas used may be displayed in units of a predetermined period of day, week, month, or year. In the example shown in FIG. 4, the operation button for displaying the power generation amount is selected, and the selected button is displayed in a mode different from the other buttons (the same applies to the screens illustrated in FIGS. 5 and 6). Furthermore, an “output control calendar” button that functions as a first operation button described later may be displayed on the home screen. In the example shown in FIG. 4, in the bar graph indicating the power generation amount and the like, the solar power generation data is displayed on the fuel cell power generation data (the same applies to the screen illustrated in FIG. 5). In this case, it becomes easy to confirm changes in the amount of power generated by solar power generation. In the graph, the amount of power generation on a specified date such as the previous day may be displayed as comparison data in a line graph. Note that the screen illustrated in FIG. 3 may be a home screen, and the screen illustrated in FIG. 4 may be a screen other than the home screen.

  3 and 4 display the time corresponding to the output control schedule, that is, the time used for executing the output control based on the output control schedule. For example, the control device 16 acquires clock information from the output control system 40 and displays the time together with the date. This time is synchronized with the power company that is the provider of the output control schedule.

  The first output unit 17 reads information on the output control period from the output control schedule, and causes the display unit 12 to display a first screen including the information. Then, the amount of power generated by the power supply system 2 in the first period and the output control period in the first period are displayed on the same time axis. Thereby, the electric power generation company can grasp | ascertain easily the influence of the electric power generation amount etc. of the electric power supply system 2 by output control. An example of the first period is a period within one day (24 hours), and may be 12 hours or 24 hours. On the first screen, for example, the power generation amount for each predetermined period shorter than the first period, such as every 30 minutes or every hour, is displayed.

  The first output unit 17 preferably displays the degree of output control together with the output control period on the first screen. The output control schedule includes, for example, the date and time when the active power supplied to the system from the power supply system 2 is suppressed, and information on the control rate indicating the degree of output control. The first output unit 17 reads control rate information from the output control schedule and causes the display unit 12 to display a first screen including the information.

  As described above, the output control schedule defines the control rate of the power supply system 2 as the degree of output control. The control rate is a predetermined time unit for every day or a specific day, such as a control rate of 50% from 9:00 to 9:30 on day A and a control rate of 100% from 9:30 to 10:00 on day A. May be specified. Here, the control rate of 50% means that 50% of the active power capable of reverse flow is limited. When the control rate is 100%, the output of the power supply system 2 is not limited and the output of 100% is obtained. Is possible.

  The first output unit 17 may form a part of the power supply system 2 on the first screen, or may further display an operation state of a predetermined device to which power is supplied from the power supply system 2. As a specific example, when the power storage device 34 is installed in the facility 1, the first output unit 17 may display the charging operation period of the power storage device 34 on the first screen. In this case, it is preferable to display the power generation amount of the power supply system 2 in the first period, the output control period in the first period, and the charging operation period of the power storage device 34 in the first period on the same time axis.

  By displaying the charging operation period of the power storage device 34 on the first screen, it is possible to easily grasp that the power generated during the output control period is effectively used by charging the power storage device 34. Alternatively, when the power storage device 34 is in a chargeable state and charging is not performed, it is possible to change the setting of the power storage device 34 to increase the amount of charge. On the first screen, the charging rate (SOC) of the power storage device 34 may be displayed together with the charging operation period.

  When the water heater is installed in the facility 1, the first output unit 17 displays at least one of the boiling operation period and the boiling increase operation period (hereinafter referred to as “boiling operation period etc.”) on the first screen. May be displayed. In this case, it is preferable to display the power generation amount of the power supply system 2 in the first period, the output control period in the first period, the boiling operation period of the water heater in the first period, and the like on the same time axis. . Here, the boiling operation is an operation for boiling required hot water in advance, and is distinguished from a boiling operation that is performed as the amount of stored hot water decreases.

  By displaying the boiling operation period of the water heater on the first screen, the power generated during the output control period is effectively used by being used for the boiling operation of the water heater, etc. Easy to grasp. Alternatively, when the boiling operation or the like is not executed even though the amount of hot water in the water heater is decreasing, it is possible to change the setting of the water heater to increase the amount of hot water. On the first screen, the amount of hot water supplied from the water heater may be displayed together with the boiling operation period and the like.

  Note that the devices whose operation state is displayed on the first screen are not limited to the power storage device 34 and the water heater, and the first screen includes a washing machine operation period, a dryer operation period, a dishwasher operation period, An electric vehicle battery charging operation period or the like may be displayed.

  FIG. 5 is a diagram illustrating an example of the first screen. As illustrated in FIG. 5, the power generation amount of the power supply system 2 and the output control period are displayed on the same time axis on the first screen, and the above control is performed as the degree of output control in the output control period. The rate is displayed. The power generation amount of the power supply system 2 is displayed as a bar graph in which the power generation amount of the solar power generation device 30 and the power generation amount of the fuel cell device 32 can be distinguished. In the first screen illustrated in FIG. 5, the power generation amount and the like are displayed in units of 30 minutes. For example, the bar graph of the power generation amount at 12:00 shows the power generation amount from 12:00 to 12:30. By matching the time interval of the bar graph indicating the power generation amount of the power supply system 2 and the time interval of the output control schedule, it becomes easier to compare the power generation amount of the power supply system 2 and the output control schedule.

  The output control period is displayed as a first bar below the bar graph indicating the power generation amount of the power supply system 2. In the example shown in FIG. 5, in the first period, April 23, 2017, 12:00 to 16:30 is displayed as the output control period. The control rate is displayed as a single straight line from 0 o'clock to 24 o'clock in the same place as the bar graph indicating the power generation amount.
