Mode for Carrying Out the Invention

[0009] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

[0010] <1. Management System> FIG. 1 is an image diagram of a management system 100 according to an embodiment of the present invention. The management system 100 manages energy. That is, the management system 100 is an energy management system. Specifically, the management system 100 manages electrical energy and thermal energy. The management system 100 is applied to, for example, a residential facility, an industrial facility, or both a residential facility and an industrial facility.

[0011] As shown in FIG. 1, the management system 100 includes a system controller 1. The management system 100 manages electrical energy and thermal energy centering on the system controller 1. The management system 100 includes a facility (electricity-related facility) provided to be able to supply electric power and a facility (heat-related facility) provided to be able to supply at least one of warm heat and cold heat. These facilities are controlled by the system controller 1.

[0012] Note that warm heat is the warm part of heat, and cold heat is the cold part of heat. That is, when heat is distinguished into warm heat and cold heat, the warm heat is warm heat and the cold heat is cold heat. For example, warm heat is air at a temperature higher than the indoor temperature, and cold heat is air at a temperature lower than the indoor temperature. In addition, the facilities shown in FIG. 1 are merely examples, and the configuration may be changed to a configuration in which any of the facilities shown in FIG. 1 is missing, or the configuration may be changed to a configuration in which a facility not shown in FIG. 1 is added.

[0013] In the example shown in FIG. 1, the management system 100 includes, as the above-described electrical-related equipment, a renewable energy power generation device 2 and a storage battery 3. The renewable energy power generation device 2 and the storage battery 3 operate under the management of the system controller 1.

[0014] The renewable energy power generation device 2 is a device that generates electricity using renewable energy such as sunlight, wind power, hydraulic power, or geothermal energy. The renewable energy power generation device 2 may be, for example, a solar power generation device or a wind power generation device. The renewable energy power generation device 2 can supply the electric power obtained by power generation to the power supply line of the management system 100. The storage battery 3 stores the electric power generated by power generation equipment such as the renewable energy power generation device 2 and discharges the stored electric power as needed. That is, the storage battery 3 can supply electric power to the power supply line of the management system 100. The storage battery 3 may be, for example, a lithium-ion battery.

[0015] Note that the management system 100 is connected to the power grid 10. The power grid 10 is a large-scale commercial power grid and supplies power to the power receiving equipment of the management system 100. The management system 100 can purchase electricity from the power grid 10 and receive power supply. The system controller 1 is provided so as to be able to control whether or not to receive power supply from the power grid 10. The system controller 1 may be provided so as to be able to control whether or not to supply power to the power grid 10.

[0016] In the example shown in FIG. 1, the management system 100 includes, as the above-described heat-related equipment, a boiler 4, a heat pump 5, and a hot water storage tank 6. The boiler 4, the heat pump 5, and the hot water storage tank 6 operate under the management of the system controller 1.

[0017] The boiler 4 can supply the thermal energy of steam or hot water obtained by the combustion of fuel such as gas to the heat supply line that the management system 100 has. The heat pump 5 operates an engine using gas fuel or the like as fuel, drives a compression unit that compresses the refrigerant, and performs temperature control by the condensation heat or evaporation heat of the refrigerant. Here, temperature control means, for example, when the heat pump 5 is applied to an air conditioner, it is the temperature adjustment of the air in a room or the like, and when the heat pump 5 is applied to a chiller, it is the temperature adjustment of the circulating liquid for the chiller. The circulating liquid can typically be exemplified by water. The heat pump 5 can execute a cooling operation for cooling the temperature control target and a heating operation for heating the temperature control target. That is, the heat pump 5 can switch between heating and cooling and supply it to the heat supply line that the management system 100 has. The hot water storage tank 6 is connected to the boiler 4 or the like and can store heat by heat-exchanging the water medium in the tank with high-temperature hot water. The heat stored in the hot water storage tank 6 can be supplied to the heat supply line that the management system 100 has.

[0018] In the example shown in FIG. 1, the management system 100 includes a cogeneration system 7 as a facility that is also used for the above-described electrical-related equipment and heat-related equipment. The cogeneration system 7 operates under the management of the system controller 1. The cogeneration system 7 drives an engine with fuel such as gas fuel and generates electricity using a generator that operates by the driving of the engine. The electric power generated by the generator can be supplied to the power supply line that the management system 100 has. In addition, the cogeneration system 7 can supply the thermal energy of steam or hot water obtained by an exhaust heat recovery boiler that uses the heat (exhaust heat) generated by the engine to the heat supply line that the management system 100 has.

[0019] Power is supplied to the power loads included in the management system 100 from the renewable energy power generation device 2, the storage battery 3, the power grid 10, or the cogeneration system 7. Examples of the power loads include electric lights and various electrical appliances. Further, for the heat loads included in the management system 100, heating or cooling is supplied from the boiler 4, the heat pump 5, the hot water storage tank 6, or the cogeneration system 7. Examples of the heat loads include air conditioners, heaters, refrigerators, freezers, hot water storage tanks, etc.

[0020] <2. System Controller> FIG. 2 is a block diagram showing the configuration of the system controller 1 according to an embodiment of the present invention. As shown in FIG. 2, the system controller 1 includes a control device 11, an input device 12, and a display device 13. That is, the management system 100 has the display device 13. The management system 100 further includes the control device 11 and the input device 12.

[0021] The control device 11 controls the entire management system 100. The control device 11 includes an integrated circuit for arithmetic operations such as a CPU, a RAM (Random Access Memory), and a ROM (Read Only Memory). The control device 11 exhibits various functions by executing arithmetic processing according to a computer program stored in a memory such as a ROM by an integrated circuit for arithmetic operations such as a CPU.

[0022] The input device 12 is provided to enable input of commands to the control device 11. The input device 12 includes at least one of, for example, a touch panel, a keyboard, a mouse, a touch pad, a button, a rotary knob, etc. For example, when the input device 12 is a touch panel, the input device 12 and the display device 13 may be an integrated device. Further, the control device 11 may be included in the integrated device.

[0023] The display device 13 displays screens for displaying various types of information related to the management system 100 and input screens for giving commands to the control device 11 under the control of the control device 11. The display device 13 is configured using, for example, a liquid crystal panel, an organic EL panel, or the like. The display device 13 may be configured to include a touch panel. In this case, as described above, the display device 13 also serves as the input device 12.

[0024] <3. Screen Display of Display Device> Next, the screen display of the display device 13 will be described in detail.

[0025] (3-1. Overview of Screen Display) FIG. 3 is a schematic diagram showing a state in which the login screen 131 is displayed on the screen 130 of the display device 13. A person (user) attempting to access the management system 100 is first required to input predetermined information on the login screen 131. That is, screens for displaying various types of information related to the management system 100 and input screens for inputting commands to the control device 11 cannot be viewed unless the user inputs the necessary information on the login screen 131.

[0026] In the present embodiment, as shown in FIG. 3, the login screen 131 has a login information input area 1311. The login information input area 1311 has a user name input area 1311a for inputting a user name, a password input area 1311b for inputting a password associated with the user name in advance, and a login button 1311c. That is, on the login screen 131, input of a user name and input of a password are required.

[0027] The input of the user name and password is performed using, for example, a keyboard or a touch panel. In a configuration where a touch panel or a mouse is used for input, the input may be performed using a soft keyboard (virtual keyboard) that appears within the login screen 131. The soft keyboard may be configured to appear within the login screen 131, for example, when the user touches or clicks on the user name input area 1311a or the password input area 1311b. A similar soft keyboard may be used for inputting characters and numbers on other types of screens other than the login screen 131.

[0028] Note that in the present embodiment, the login screen 131 has a header area 200 extending in the left - right direction of the screen 130 at the upper end. Also, the login screen 131 has a footer area 300 extending in the left - right direction of the screen 130 at the lower end. The header area 200 and the footer area 300 are appropriately displayed on other types of screens other than the login screen 131. In the header area 200, for example, a company logo, a menu related to screen display, etc. are displayed. In the footer area 300, for example, the time, the user name permitted to log in, etc. are displayed.

[0029] After the user name and password are input, when the login button 1311c is operated by touch or the like, the home screen 132 is displayed. Note that if at least one of the user name and password is inappropriate, an error display is shown on the login screen 131 and the home screen 132 is not displayed.

[0030] FIG. 4 is a schematic diagram showing a state in which the home screen 132 is displayed on the screen 130 of the display device 13. In the present embodiment, the home screen 132 is a screen devised so that the demand and supply of electric energy and thermal energy in the management system 100 can be grasped at a glance. In the example shown in FIG. 4, the home screen 132 has a header area 200. The header area 200 includes a menu area 400 indicating the types of selectable screen displays. In the present embodiment, the menu area 400 includes a home button 401, a status monitoring button 402, a graph button 403, a device management button 404, and an operation setting button 405. For the operation of each button 401 to 405, for example, a touch panel, a mouse, or a keyboard may be used.

[0031] In the example shown in FIG. 4, since the home screen 132 is selected, a selection display indicating the selected state is provided. Specifically, as the selection display, a frame surrounding the home button 401 is displayed. However, the selection display is not limited to a frame surrounding the button, and may be other configurations such as a configuration in which the color of the button is different from that of other buttons or a configuration in which the button is hatched differently from other buttons.

[0032] When the status monitoring button 402 is selected, a status monitoring screen is displayed. The status monitoring screen displays details of the operating status of each device included in the management system 100. Each device includes a thermal device and an electrical device. The thermal devices include, for example, the above-described heat-related equipment (including equipment shared with the electrical-related equipment) and thermal loads (such as air conditioning equipment and foot bath equipment). The electrical devices include, for example, the above-described electrical-related equipment (including equipment shared with the heat-related equipment) and electrical loads.

[0033] When the graph button 403 is selected, a graph screen is displayed. The graph screen displays, for example, a graph showing the transition of the magnitudes of the thermal load and the electrical load every hour of a day and the breakdown of the output of each device with respect to the load.

[0034] When the device management button 404 is selected, a device management screen is displayed. The device management screen displays device management information including input / output information of each device.

[0035] When the operation setting button 405 is selected, an operation setting screen is displayed. The operation setting screen includes an input screen for inputting information related to the operation of the management system 100. The information related to the operation includes information related to the control method of the management system 100. In the present embodiment, on the operation setting screen, it is configured such that the validity and invalidity of optimization control and demand control can be selected.

[0036] Optimization control is a control method that performs control according to an optimization target selected by a user (a representative example is a customer) who uses the management system 100. Examples of the optimization target include cost priority that prioritizes reduction of various fees borne by the user, carbon dioxide emission amount priority that prioritizes reduction of carbon dioxide emissions generated during device operation, and primary energy consumption amount priority that prioritizes reduction of the consumption amount of primary energy required for device operation. In the present embodiment, the user can select any one of these three optimization targets. When the user selects cost priority, assuming that the optimization control is set to be effective, operation control that prioritizes cost reduction will be performed. When the user selects carbon dioxide emission amount priority, assuming that the optimization control is set to be effective, operation control that prioritizes reduction of carbon dioxide emissions will be performed. When the user selects primary energy consumption amount priority, assuming that the optimization control is set to be effective, operation control that prioritizes reduction of the consumption amount of primary energy will be performed.

[0037] Demand control is a control method that controls the devices included in the management system 100 so that the power received from the power grid 10 does not exceed the target demand value. The target demand value is set to be equal to or less than the contract power. When the optimization control and the demand control are set to be effective, in principle, the management system 100 operates with the optimization control and switches to the demand control when the received power approaches the target demand value.

[0038] As can be understood from the above description, the display device 13 can switch and display the information managed by the management system 100 on a plurality of types of screens. In the example shown in FIG. 4, it is possible to switch to at least five types of screens: a home screen, a status monitoring screen, a graph screen, a device management screen, and an operation setting screen. However, these screen displays are merely examples, and the types of screens that can be displayed by the display device 13 may be changed as appropriate.

[0039] In addition, in the example shown in FIG. 4, the menu area 400 includes a forward button 406. When the forward button 406 is operated by touch or the like, the types of buttons for selecting the screen type displayed in the menu area 400 are switched. That is, in the example shown in FIG. 4, it is possible to display screens other than the five types of screens: the home screen, the status monitoring screen, the graph screen, the device management screen, and the operation setting screen. Examples of screens other than the above five types include a user management screen for inputting user information and a screen setting screen for setting conditions related to the screen.

[0040] Also, in the example shown in FIG. 4, the home screen 132 has a footer area 300. The footer area 300 includes an icon area 301 indicating the user name and a time information area 302 including the date and time. In the present embodiment, when the icon area 301 is operated by touch or the like, it is possible to log out. As a preferred configuration, when the icon area 301 is operated, a confirmation screen for confirming whether to execute the logout is pop-up displayed on the screen, and when logout is permitted on the confirmation screen, the logout is executed.

[0041] In the present embodiment, as a preferred form, various screens selectable by the menu area 400 such as the home screen 132 further include a control state display area 500 indicating the control state of the management system 100. With such a configuration, the user can obtain information on the control state of the management system 100 on a screen where various information can be grasped. That is, the convenience of the user can be improved.

[0042] In the embodiment, the control state display area 500 is included in the header area 200. Specifically, it is arranged to the immediate right of the menu area 400. However, the position of the control state display area 500 may be changed as appropriate. In the example shown in FIG. 4, "Optimization" is displayed in the control state display area 500. This indicates that the management system 100 is operating under the above-described optimization control. In addition, for example, "Demand Control", "Stopped", etc. are also displayed in the control state display area 500.

[0043] (3-2. Operation Setting Screen) [3-2-1. Overview of Operation Setting Screen] FIG. 5 is a schematic diagram showing a state in which the operation setting screen 133 is displayed on the screen 130 of the display device 13. The operation setting screen 133 can be selected by performing an operation such as a touch on the operation setting button 405 displayed in the menu area 400.

[0044] Specifically, the operation setting screen 133 includes a sub-menu area 410. The operation setting screen 133 displays content corresponding to the button selected from the buttons 411a, 411b, 411c, 411d, and 411e displayed in the sub-menu area 410. In this embodiment, the buttons displayed in the sub-menu area 410 of the operation setting screen 133 include a load button 411a, a charge button 411b, a calendar button 411c, an operation plan button 411d, and a demand control button 411e. FIG. 5 shows the screen when the load button 411a is selected.

[0045] In addition, in the present embodiment, when the operation setting button 405 is selected while a screen other than the operation setting screen 133 (for example, the home screen 132 or the like) is being displayed, a specific button among the plurality of buttons 411a to 411e displayed in the sub-menu area 410 is automatically selected, and the screen corresponding to the selected button is displayed. Which button is to be the specific button may be determined as appropriate. For example, when the load button 411a is designated as the specific button, when the operation setting button 405 is selected, the load button 411a is automatically selected and a screen related to load setting is displayed.

[0046] By the way, the energy demand in the management system 100 is not always the same every day and usually varies. On the other hand, the daily energy demand tends to be the same if the type of day is the same. Taking this into account, in the present embodiment, for the daily operation of the management system 100, a configuration is adopted in which any one of a plurality of setting patterns classified according to the type of day is used. That is, the management system 100 has a plurality of setting patterns. The type of day is, for example, each day of the week, holidays, weekdays, etc. And in the present embodiment, the display device 13 is configured to display a setting screen (operation setting screen) 133 that can switch and display a plurality of setting patterns for each pattern.

[0047] With such a configuration, since the daily operation setting of the management system 100 can be selected and determined from any of the plurality of setting patterns, the management system 100 can be appropriately operated while reducing the burden of the operation setting of the management system 100. And since each of the plurality of setting patterns can be displayed on a separate screen, it is possible to easily check and input information for each setting pattern.

[0048] Specifically, as shown in FIG. 5, the operation setting screen 133 has a tab area 420 below the sub-menu area 410. In the tab area 420, ten types of setting pattern tabs 421, namely, "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday", "Holiday", "Special Day (1)", and "Special Day (2)", are displayed. "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", and "Sunday" are each types of days of the week. For example, "Monday" refers to Monday.

[0049] When the tab for Monday is selected among the ten types of setting pattern tabs 421, the Monday pattern is displayed. When the tab for Tuesday is selected, the Tuesday pattern is displayed. When the tab for Wednesday is selected, the Wednesday pattern is displayed. When the tab for Thursday is selected, the Thursday pattern is displayed. When the tab for Friday is selected, the Friday pattern is displayed. When the tab for Saturday is selected, the Saturday pattern is displayed. When the tab for Sunday is selected, the Sunday pattern is displayed. When the tab for Holiday is selected, the holiday pattern is displayed. When the tab for Special Day (1) is selected, the Special Day (1) pattern is displayed. When the tab for Special Day (2) is selected, the Special Day (2) pattern is displayed. Note that FIG. 5 shows the screen when the tab for Special Day (2) is selected.

[0050] That is, in this embodiment, for the daily operation of the management system 100, any one of the Monday pattern, Tuesday pattern, Wednesday pattern, Thursday pattern, Friday pattern, Saturday pattern, Sunday pattern, holiday pattern, Special Day (1) pattern, and Special Day (2) pattern is applied.

[0051] As shown in FIG. 5, a load button 411a and a charge button 411b are displayed in the sub-menu area 410 of the operation setting screen 133. As can be understood from this, in this embodiment, the operation settings include a load setting, which is a setting related to the load, and a charge setting, which is a setting related to the charge. That is, the setting patterns specifically include a load setting pattern and a charge setting pattern.

[0052] Note that the load includes at least one of an electric load and a heat load. Further, the heat load includes at least one of a heating load and a cooling load. In the present embodiment, the load includes an electric load, a heating load, and a cooling load.

[0053] When the load button 411a is operated by touch or the like, a load setting screen is displayed. The screen 133 shown in FIG. 5 is a load setting screen. That is, FIG. 5 can also be represented as a schematic diagram showing a state in which the load setting screen 133 is displayed on the screen 130 of the display device 13. When the charge button 411b is operated by touch or the like, a charge setting screen is displayed. That is, the setting screen (operation setting screen) 133 can switch between and display a load setting screen and a charge setting screen.

[0054] When the calendar button 411c in the sub-menu area 410 is operated by touch or the like, a calendar screen is displayed. Details of the calendar screen will be described later. When the operation plan button 411d is operated by touch or the like, an operation plan screen is displayed. The operation plan screen is an input screen that enables selection of whether the above-described optimization control and demand control are valid or invalid. When the demand control button 411e is operated by touch or the like, a demand control screen is displayed. The demand control screen is an input screen that enables detailed setting of demand control.

[0055] As can be seen from the above, the operation setting screen 133 can switch between and display, in detail, a load setting screen, a charge setting screen, a calendar screen, an operation plan screen, and a demand control screen. Hereinafter, the load setting screen, the charge setting screen, and the calendar screen will be described in detail.

[0056] [3-2-2. Load Setting Screen] The load setting screen displays set values for each predetermined time for at least one of an electric load, a heating load, and a cooling load. Note that each predetermined time is, for example, every hour. The set value of the load is a predicted value of the magnitude of the load.

[0057] As described above, the operation setting screen 133 shown in FIG. 5 exemplifies a load setting screen. As shown in FIG. 5, in the present embodiment, the load setting screen 133 displays the set values for each hour for the electric load, the thermal load, and the cooling / heating load. Specifically, the load setting screen switches for each load setting pattern and displays the set values for each hour for the electric load, the thermal load, and the cooling / heating load. Note that the switching of the load setting pattern is performed using the setting pattern tab 421 as described above.

[0058] In the example shown in FIG. 5, the tab for the special day (2) is selected, and the set values for each hour of the electric load, the thermal load, and the cooling / heating load on the special day (2) are shown. The screen configuration is the same for each load setting pattern. For this reason, the case where the tab for the special day (2) is selected will be described as a representative example.

[0059] As shown in FIG. 5, a table 1331 is displayed below the tab area 420 on the load setting screen 133. The set values are displayed in each cell 1331a of the table 1331. Note that the hatched numbers in the table 1331 are the times displayed in the 24-hour format. For example, the hatched number "15" means 15:00. The set values for one day (24 hours) are displayed for each hour for each of the electric load, the thermal load, and the cooling / heating load.

[0060] In the example shown in FIG. 5, a graph 1332 is displayed below the table 1331. The horizontal axis of the graph 1332 is time, with the left end being 0:00 and the right end being 24:00. The vertical axis of the graph 1332 is the amount of load displayed in kilowatts. The graph 1332 is a graph of the set values displayed in the table 1331. By displaying the graph 1332 in addition to the table 1331, it becomes easier to grasp the time change of the set values for each load.

[0061] The load setting screen 133 is a screen where the set value of the load can be manually input. For example, when the user wants to modify the set value of the load, the user can easily modify the set value. Note that the manual input of the load set value may be used immediately after the management system 100 is introduced. And after the set value is first input, the control device 11 may be configured to automatically determine the set value according to the operation results. The user may manually modify the value automatically set by the control device 11.

[0062] In the example shown in FIG. 5, an input value area 1333 for inputting a set value (predicted value) is provided between the tab area 420 and the table 1331. When the user manually inputs a set value for each of the power load, the heat load, and the cooling load, the user selects the cell 1331a for which the user wants to input the set value by touching or the like. At this time, the user may select one cell 1331a or a plurality of cells 1331a. With the cell 1331a selected, the user inputs the value to be set in the input value area 1333. After the user inputs a value into the input value area 1333, the user operates the reflection button 1334 displayed beside the input value area 1333 by touching or the like. Thereby, the value input in the input value area 1333 is displayed for the selected cell 1331a. Note that the selection of the cell 1331a can be canceled by operating the deselection button 1335 displayed beside the right of the reflection button 1334 by touching or the like. After the input of the value to each cell 1331a is completed, the user can confirm the value input to each cell 1331a by operating the apply button 1336 existing on the right side away from the deselection button 1335 by touching or the like.

[0063] In this embodiment, check boxes 1331b are displayed at the left ends of the three load columns shown in table 1331. When a check box 1331b is operated by touch or the like, a check mark (not shown) is entered in the check box 1331b, and all cells 1331a of the corresponding load are selected. That is, by using the check box 1331b, values can be input collectively into all cells 1331a for the loads with check marks. For example, it is convenient when you want to input the same value multiple times.

[0064] Also, in this embodiment, a batch button 422 is provided on the right end side of the tab area 420. FIG. 6 is a schematic diagram showing an example of a screen when the batch button 422 is selected on the load setting screen 133. The basic configuration of the screen 133a displayed by selecting the batch button 422 is the same as the screen configuration (see FIG. 5) when any one of the setting pattern tabs 421 is selected. However, when the batch button 422 is selected, as shown in FIG. 6, the values of the respective cells 1331a in the table 1331 are blank. The user can collectively perform load settings for all load setting patterns (10 patterns as described above in this embodiment) by performing operations such as entering values in the input value area 1333 in the same manner as described with reference to FIG. 5 on the screen 133a displayed by selecting the batch button 422.

[0065] That is, the load setting screen 133 displays a batch button 422 that causes a screen 133a to be displayed that enables manual input of load setting values in a batch for a plurality of setting patterns (specifically, load setting patterns). When, as in this embodiment, there are three types of targets for load setting (electric power load, heat load, and cooling / heating load), it may be configured such that the settings for all load setting patterns can be collectively performed for all or a plurality of these three types. As another example, it may also be configured such that the settings for all load setting patterns can be collectively performed separately for the three types.

[0066] [3 - 2 - 3. Screen for tariff setting] The charge setting screen displays the set values for the charges of the energy required when operating the facilities of the management system 100 at predetermined time intervals. The predetermined time intervals are, for example, every hour. The energy charges include, for example, electricity charges and gas charges.

[0067] FIG. 7 is a schematic diagram showing a state in which the charge setting screen 133b is displayed on the screen 130 of the display device 13. The charge setting screen 133b is displayed when the charge button 411b displayed in the sub-menu area 410 is selected. As shown in FIG. 7, in this embodiment, the charge setting screen 133b displays the set values every hour for electricity, gas, and gas for cogeneration. Specifically, the charge setting screen 133b switches for each charge setting pattern and displays the set values every hour for electricity, gas, and gas for cogeneration. The switching of the charge setting pattern is performed using the setting pattern tab 421 as described above.

[0068] In the example shown in FIG. 7, the tab for the special day (2) is selected, and the set values every hour for electricity, gas, and gas for cogeneration on the special day (2) are shown. The screen configuration is the same for each charge setting pattern. For this reason, the case where the tab for the special day (2) is selected will be described as a representative example.

[0069] As shown in FIG. 7, a table 1331X is displayed below the tab area 420 on the charge setting screen 133b. The set values are displayed in each cell 1331Xa of the table 1331X. The numbers with hatching in the table 1331X are the times displayed in the 24-hour format. For each of electricity, gas, and gas for cogeneration, the set values for one day (24 hours) are displayed every hour.

[0070] In the example shown in FIG. 7, a graph 1332X is displayed below a table 1331X. The horizontal axis of the graph 1332X represents time, with the left end being 0 o'clock and the right end being 24 o'clock. The vertical axis of the graph 1332X represents the fee. In the example shown in FIG. 7, the unit of the fee is yen. The graph 1332X is a graphical representation of the set values displayed in the table 1331X. By displaying the graph 1332X in addition to the table 1331X, it becomes easier to grasp the time change of the set values of each fee.

[0071] The fee setting screen 133b is a screen on which the set value of the fee can be manually input. For example, when the user wants to modify the set value of the fee, the user can easily modify the set value. In this embodiment, manual input of the set value is possible on both the load setting screen 133 and the fee setting screen 133b. However, this is an example, and at least one of the load setting screen 133 and the fee setting screen 133b may be configured as a screen on which the set value can be manually input.

[0072] Note that the input procedure for the set value using the input value area 1333X, the reflection button 1334X, the selection cancellation button 1335X, and the application button 1336X is the same as that for the load setting screen 133, so the description is omitted here. Also, on the fee setting screen 133b, similar to the case of the load setting screen 133, by using the check box 1331Xb, values can be input collectively to all cells 1331Xa for the fees of the items with check marks.

[0073] Also, on the fee setting screen 133b, similar to the case of the load setting screen 133, a batch button 422 is provided in the tab area 420. By using the screen displayed by the batch button 422, the fee settings for all fee setting patterns (10 patterns as described above in this embodiment) can be performed collectively. That is, the fee setting screen 133b displays a batch button 422 that enables the manual input of the set value of the fee to be performed collectively for a plurality of setting patterns (specifically, fee setting patterns).

[0074] In addition, when there are three types of objects for which fee settings are made as in this embodiment, it may be configured such that all or a plurality of these three types can be grouped together and all fee setting patterns can be set collectively. As another example, it may also be configured such that the settings of all fee setting patterns can be set collectively for each of the three types separately.

[0075] Also, in this embodiment, the batch button is displayed on both the load setting screen 133 and the fee setting screen 133b, but this is merely an example. At least one of the load setting screen 133 and the fee setting screen 133b may be configured to display the batch button.

[0076] Also, in this embodiment, the fee setting screen 133b displays a season selection button 1337 for selecting a summer screen and a winter screen. This is considered in view of the fact that the fee settings for electricity and gas may change depending on the season.

[0077] As shown in FIG. 7, the season selection button 1337 includes a summer selection area 1337a and a winter selection area 1337b. In FIG. 7, the summer selection area 1337a is selected. When the summer selection area 1337a is selected, a screen reflecting the summer setting values is displayed in the table 1331X and the graph 1332X. Also, the user can input the summer setting values by selecting the summer selection area 1337a. When the winter selection area 1337b is selected, a screen reflecting the winter setting values is displayed in the table 1331X and the graph 1332X. Also, the user can input the winter setting values by selecting the winter selection area 1337b.

[0078] Also, in this embodiment, the fee setting screen 133b further displays a period setting button 423 for setting the summer period and the winter period.

[0079] FIG. 8 is a schematic diagram showing an example of a screen when the period setting button 423 is selected on the charge setting screen 133b. In the present embodiment, since it is possible to perform charge setting for electricity, gas, and gas for cogeneration, it is possible to perform period setting for these three types.

[0080] In the example shown in FIG. 8, for electricity, the summer period can be set. The period other than the summer period is the winter period. Also, for gas and gas for cogeneration, the winter period can be set. The period other than the winter period is the summer period. After a period is input in the period input area 1330 for each item, when the apply button 1336Y is operated by touch or the like, the set period is determined. The electricity and gas charges used for calculating the planned value of the optimization control are determined according to the set period setting.

[0081] Note that for electricity, it may be possible to set the winter period instead of the summer period. Also, for gas (including gas for cogeneration), it may be possible to set the summer period instead of the winter period. For electricity and gas (including gas for cogeneration), a configuration may be adopted in which the summer period and the winter period can be set separately. However, as in the present embodiment, it is possible to make it less likely to cause an error in the period setting by making it possible to set only one of the summer period and the winter period, and making the period outside the set period the other period.

[0082] [3-2-4. Calendar Screen] The display device 13 further displays a calendar screen that enables setting, using a calendar, which of a plurality of setting patterns is to be applied to each day. That is, the display device 13 further displays a calendar screen that enables setting, using a calendar, which of a plurality of setting patterns is to be applied to a predetermined day. Note that in the present embodiment, the plurality of setting patterns are composed of 10 types of setting patterns as described above.

[0083] FIG. 9 is a schematic diagram showing a state in which a calendar screen 133d is displayed on the screen 130 of the display device 13. Note that the calendar screen 133d is displayed when a calendar button 411c displayed in a sub-menu area 410 in the operation setting screen 133 is selected.

[0084] In the present embodiment, as shown in FIG. 9, a first calendar 1338a and a second calendar 1338b are displayed on the calendar screen 133d. The second calendar 1338b is a calendar of the next month of the first calendar 1338a. The calendar displayed on the calendar screen 133d can be changed by operating a previous month button 601 arranged to the left of the first calendar 1338a and a next month button 602 arranged to the right of the second calendar 1338b by touch or the like.

[0085] In the example shown in FIG. 9, the first calendar 1338a is a calendar of February, and the second calendar 1338b is a calendar of March. When the previous month button 601 is operated by touch or the like, the first calendar 1338a becomes a calendar of January, and the second calendar 1338b becomes a calendar of February. When the next month button 602 is operated by touch or the like, the first calendar 1338a becomes a calendar of March, and the second calendar 1338b becomes a calendar of April. Note that the number of calendars displayed on the calendar screen 133d may be one or three or more. Also, the unit of the month changed by the previous month button 601 and the next month button 602 may not be one month at a time, but may be two months at a time.

[0086] As shown in FIG. 9, on the calendar screen 133d, four buttons are displayed to the right of the second calendar 1338b and farther away from the month advance button 602. The four buttons include an apply button 1336Z, a holiday button 1339a, a special day (1) button 1339b, a special day (2) button 1339c, and a cancel button 1339d. Also, a selection cancel button 1335Y is displayed in the upper left side of the first calendar 1338a. These six buttons 1335Y, 1336Z, 1339a to 1339d are used to determine the setting pattern to be applied to each date. Note that the arrangement of these six buttons 1335Y, 1336Z, 1339a to 1339d may be changed as appropriate.

[0087] Each of the calendars 1338a and 1338b has rectangular calendar cells 1338c into which each date can be entered. The display state of the calendar cell 1338c differs depending on the type of setting pattern applied. In the example shown in FIG. 9, when the day-of-week pattern of the day of the week to which the date in the calendar cell 1338c belongs is applied, the background for the black characters in the calendar cell 1338c is white. Note that applying the day-of-week pattern of the day of the week to which the date belongs means, for example, when the day of the week to which the date belongs is Monday, the Monday pattern is applied as the setting pattern.

[0088] When the holiday pattern is applied to the setting pattern, the background for the black characters in the calendar cell 1338c is made the same as the background of the characters in the holiday button 1339a. When the special day (1) pattern is applied to the setting pattern, the background for the black characters in the calendar cell 1338c is made the same as the background of the characters in the special day (1) button 1339b. When the special day (2) pattern is applied to the setting pattern, the background for the black characters in the calendar cell 1338c is made the same as the background of the characters in the special day (2) button 1339c.

[0089] According to the calendar screen 133d shown in FIG. 9, for example, on February 3, the pattern of Monday (Monday pattern), which is the day of the week to which that day belongs, is applied as the setting pattern. For example, on February 24, instead of the pattern of Monday, which is the day of the week to which that day belongs, the holiday pattern is applied as the setting pattern.

[0090] FIGS. 10A and 10B are diagrams for explaining the procedure of setting any one of the setting patterns for each day using the calendar screen 133d. Specifically, FIG. 10A is a diagram during setting, and FIG. 10B is a diagram after setting.

[0091] First, the user selects the calendar cell 1338c of the date to be set by touching or the like. At this time, the user may select only one calendar cell 1338c, or may select a plurality of calendar cells 1338c. In FIG. 10A, the user has selected a plurality of calendar cells 1338c. In FIG. 10A, the selected calendar cell 1338c is indicated by a broken line frame. Specifically, for February, the calendar cells 1338c of the days belonging to Monday except the 24th are selected, and for March, all the calendar cells 1338c of the days belonging to Monday are selected. The cancellation of the selection can be performed by operating the deselection button 1335Y.

[0092] While the calendar cell 1338c is selected, the user selects any one of the holiday button 1339a, special day (1) button 1339b, special day (2) button 1339c, and cancel button 1339d. In FIG. 10A, the special day (1) button 1339b is selected. When the special day (1) button 1339b is selected, as shown in FIG. 10B, the selected calendar cell 1338c is displayed as the special day (1). When the apply button 1336Z is selected in this state, the setting pattern for each day is determined.

[0093] In the above example, if the holiday button 1339a is selected instead of the special day (1) button 1339b, the selected calendar cell 1338c will display as a holiday, and for the date displayed as a holiday, the holiday setting pattern will be applied. Also, if the special day (2) button 1339c is selected instead of the special day (1) button 1339b, the selected calendar cell 1338c will display as special day (2), and for the date displayed as special day (2), the special day (2) setting pattern will be applied.

[0094] By the way, the cancel button 1339d is a button for canceling the setting patterns specially provided separately from the days of the week such as the holiday pattern, the special day (1) pattern, and the special day (2) pattern. For this reason, in the example described above, when the cancel button 1339d is selected instead of the special day (1) button 1339b, the selection of the selected calendar cell 1338c will be canceled without changing the display. For example, when the cancel button 1339d is selected with the calendar cell 1338c of February 24 selected, the calendar cell 1338c of February 24 will have a white background for the black - colored numbers. And on February 24, the pattern of the day of the week to which the date belongs, i.e., the Monday pattern (Monday pattern), will be applied as the setting pattern.

[0095] [3 - 2 - 5. Variation Example] FIG. 11 is a schematic diagram showing the load setting screen 133X of the variation example. The load setting screen 133X shown in FIG. 11 is generally the same as the load setting screen 133 shown in FIG. 5 described above. The screen 133X shown in FIG. 11 is displayed as a screen showing the operation setting for the next day. Specifically, a state is assumed where it is estimated that the next day is a day to which the special day (2) pattern should be applied, and the setting pattern tab 421 has the special day (2) tab selected. In the load setting screen 133X shown in FIG. 11, the estimated reason button 424 is displayed in the tab area 420, which is different from the example shown in FIG. 5.

[0096] In a modification, the management system 100 is provided so as to be able to estimate at least the setting pattern to be applied the next day. In a preferred form, the management system 100 is provided so as to be able to estimate at least the load setting pattern to be applied the next day. In the present embodiment, the load setting pattern obtained by estimation is any one of the above-described 10 types of patterns. It may be configured to estimate only the load setting pattern for the next day, or may be configured to estimate the load setting pattern to be applied for a plurality of days after the next day. The estimation of the load setting pattern to be applied is performed by the control device 11.

[0097] The above-described estimation reason button 424 is a button for displaying the reason for estimating the setting pattern (load setting pattern in this example) to be applied. When the estimation reason button 424 is operated by touch or the like, an estimation reason display screen indicating the estimation reason is displayed. That is, the display device of the modification further displays an estimation reason display screen indicating the reason for estimating the setting pattern (load setting pattern in this example).

[0098] FIG. 12 is a schematic diagram showing a state in which an estimation reason display screen 133X1 is displayed on the screen 130 of the display device of the modification. The estimation reason display screen 133X1 shown in FIG. 12 is a screen in which the estimation reason button 424 is selected and displayed on the screen 133X shown in FIG. 11. As shown in FIG. 12, the estimation reason display screen 133X1 includes an estimation reason display area Ar for displaying the estimation reason and a graph area Gr for showing a graph related to the estimation reason. In the present modification, the estimation reason display area Ar is a portion for explaining the estimation reason in characters. The graph area Gr is an area for showing, for example, a graph indicating the basis of the estimation reason.

[0099] In the example shown in FIG. 12, the horizontal axis of the graph shown in the graph area Gr is the maximum temperature of the day, and the vertical axis is the maximum cooling and heating load. In the graph shown in FIG. 12, the actual values of a plurality of past days are plotted. And in the graph, the results of grouping the past actual values by a grouping algorithm using, for example, artificial intelligence (AI) or the like are shown. Specifically, grouping is performed as to whether or not it corresponds to a special day (2) (for example, a busy day). Note that those for which it was not possible to determine whether or not it was a special day (2) are classified as undeterminable. According to the graph, it is possible to determine whether or not it is a special day (2) depending on whether or not the maximum temperature of the day exceeds 29°C. In the example shown in FIG. 12, based on the fact that the maximum temperature of the next day is predicted to be 35°C and the determination method based on the threshold value of 29°C based on the above graph, it is estimated that the next day is a special day (2), and the setting pattern is set as the special day (2) pattern, which is displayed in the estimation reason display area Ar. By providing the graph area Gr, it becomes easier for the user to judge the validity of the estimation reason.

[0100] Note that a user who determines that the estimation reason is not valid can, for example, change the set value of the load on the load setting screen or change the setting pattern corresponding to that day on the calendar screen.

[0101] FIG. 13 is a schematic diagram showing a calendar screen 133Y of another modification. As shown in FIG. 13, the estimation reason button 424A may be displayed on the calendar screen 133Y. The position of the estimation reason button 424A shown in FIG. 13 is an example, and the position may be changed as appropriate. In the example shown in FIG. 13, when the estimation reason button 424A is operated by touch or the like in a state where the calendar cell 1338c is selected, an estimation reason display screen 133Y1 for displaying the estimation reason is pop-up displayed. In the example shown in FIG. 13, a graph area is not provided in the estimation reason display screen 133Y1, but a graph area may be provided. Note that the pop-up display is an example, and an estimation reason display screen for displaying the estimation reason may be switched and displayed from the calendar screen 133Y.

[0102] <4. Precautions, etc.> Various technical features disclosed in this specification can be modified in various ways without departing from the gist of the technical creation. In addition, a plurality of embodiments and modification examples shown in this specification may be implemented in combination as far as possible.
