[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 a conceptual 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. In particular, the management system 100 manages electric energy and thermal energy. The management system 100 is applied to, for example, residential facilities, industrial facilities, or residential and industrial facilities.

[0011] As shown in Fig. 1, the management system 100 includes a system controller 1. The management system 100 manages electric energy and thermal energy with the system controller 1 at its core. The management system 100 is configured to include equipment (electrical equipment) that is capable of supplying electric power, and equipment (thermal equipment) that is capable of supplying at least one of hot and cold energy. These pieces of equipment are controlled by the system controller 1.

[0012] Note that hot heat is warm heat, and cold heat is cold heat. In other words, when heat is classified into warm heat and cold heat, warm heat is hot heat, and cold heat is cold heat. For example, hot heat is air that is at a higher temperature than the room temperature, and cold heat is air that is at a lower temperature than the room temperature. Furthermore, the equipment shown in FIG. 1 is merely an example, and the configuration may be changed to one in which any of the equipment shown in FIG. 1 is missing, or to one in which equipment not shown in FIG. 1 is added.

[0013] 1, the management system 100 includes, as the above-mentioned electrical 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 control of a system controller 1.

[0014] The renewable energy power generation device 2 is a device that generates power using renewable energy such as solar, wind, hydroelectric, 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 is capable of supplying the power obtained by power generation to a power supply line of the management system 100. The storage battery 3 stores power generated by a power generation facility such as the renewable energy power generation device 2, and discharges the stored power as needed. In other words, the storage battery 3 is capable of supplying power to the power supply line of the management system 100. The storage battery 3 may be, for example, a lithium-ion battery.

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

[0016] 1, the management system 100 includes, as the heat-related facilities, a boiler 4, a heat pump 5, and a hot water tank 6. The boiler 4, the heat pump 5, and the hot water tank 6 operate under the control of a system controller 1.

[0017] The boiler 4 can supply the thermal energy of steam or hot water obtained by burning a fuel such as gas to the heat supply line of the management system 100. The heat pump 5 operates an engine fueled by gas or the like to drive a compressor that compresses a refrigerant, thereby controlling temperature using the condensation heat or evaporation heat of the refrigerant. Here, temperature control refers to, for example, adjusting the temperature of indoor air when the heat pump 5 is applied to an air conditioner, or adjusting the temperature of the circulating fluid for the chiller when the heat pump 5 is applied to a chiller. A representative example of the circulating fluid is water. The heat pump 5 can perform a cooling operation to cool a temperature-controlled object and a heating operation to heat the temperature-controlled object. In other words, the heat pump 5 can switch between hot and cold energy and supply it to the heat supply line of the management system 100. The hot water storage tank 6 is connected to the boiler 4 or the like and can store hot energy by heat exchange between the aqueous medium in the tank and high-temperature hot water. The heat stored in the hot water tank 6 can be supplied to a 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 used for both the electrical and thermal facilities. The cogeneration system 7 operates under the control of a system controller 1. The cogeneration system 7 drives an engine using a fuel such as gas fuel, and generates electricity using a generator that is driven by the engine. The electricity generated by the generator can be supplied to a power supply line of the management system 100. The cogeneration system 7 can also supply thermal energy of steam or hot water obtained in a heat recovery boiler that utilizes heat (waste heat) generated by the engine to a heat supply line of the management system 100.

[0019] Electric power is supplied to the power load included in the management system 100 from a renewable energy power generation device 2, a storage battery 3, a power grid 10, or a cogeneration system 7. Examples of the power load include electric lights and various electrical appliances. Furthermore, hot or cold heat is supplied to the thermal load included in the management system 100 from a boiler 4, a heat pump 5, a hot water tank 6, or a cogeneration system 7. Examples of the thermal load include an air conditioner, a heating device, a refrigerator, a freezer, a hot water tank, etc.

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

[0021] The control device 11 controls the entire management system 100. The control device 11 is configured to include an integrated circuit for calculations such as a CPU, a RAM (Random Access Memory), and a ROM (Read Only Memory), etc. The control device 11 performs various functions by the integrated circuit for calculations such as the CPU executing calculation processes in accordance with computer programs stored in memory such as the ROM.

[0022] The input device 12 is provided to enable input of commands to the control device 11. The input device 12 is configured to include 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. Furthermore, the control device 11 may be included in this integrated device.

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

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

[0025] (3-1. Screen display overview) 3 is a schematic diagram showing a state in which a login screen 131 is displayed on a screen 130 of the display device 13. A person (user) who wishes to access the management system 100 is first required to input predetermined information on the login screen 131. In other words, the screens that display various information related to the management system 100 and the 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] 3, the login screen 131 has a login information input area 1311. The login information input area 1311 has a username input area 1311a for inputting a username, a password input area 1311b for inputting a password previously associated with the username, and a login button 1311c. That is, the login screen 131 requests input of a username and a password.

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

[0028] In this embodiment, the login screen 131 has a header area 200 at the top that extends in the left-right direction of the screen 130. The login screen 131 also has a footer area 300 at the bottom that extends in the left-right direction of the screen 130. The header area 200 and footer area 300 are also displayed as appropriate on screens other than the login screen 131. For example, the header area 200 displays a company logo, a menu related to the screen display, etc. The footer area 300 displays, for example, the time, the name of a user who is permitted to log in, etc.

[0029] After the username and password are entered, when the login button 1311c is operated by touching or the like, the home screen 132 is displayed. If at least one of the username and password is incorrect, an error message is displayed 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 a home screen 132 is displayed on the screen 130 of the display device 13. In this embodiment, the home screen 132 is a screen designed to allow the demand and supply of electric energy and thermal energy in the management system 100 to 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 that indicates the types of screen display that can be selected. In this 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 settings button 405. Each of the buttons 401 to 405 may be operated using, for example, a touch panel, a mouse, or a keyboard.

[0031] 4, home screen 132 is in a selected state, and therefore a selection indication indicating this selected state is displayed. In detail, a frame surrounding home button 401 is displayed as the selection indication. However, the selection indication is not limited to a frame surrounding a button, and other configurations may be used, such as a configuration in which the button is a different color from 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 thermal devices and electrical devices. Thermal devices include, for example, the above-mentioned thermal-related equipment (including equipment that also serves as electrical-related equipment) and thermal loads (air conditioning equipment, footbath equipment, etc.). Electrical devices include, for example, the above-mentioned electrical-related equipment (including equipment that also serves as thermal-related equipment) and power 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 magnitude of the heat load and power load for each hour of the day and a breakdown of the output of each device relative 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 this embodiment, the operation setting screen is configured to allow selection of whether optimization control and demand control are enabled or disabled.

[0036] Optimization control is a control method that performs control according to an optimization target selected by a user (a typical example is a customer) who uses the management system 100. Examples of optimization targets include cost priority, which prioritizes reducing various fees borne by the user; carbon dioxide emission priority, which prioritizes reducing carbon dioxide emissions generated by equipment operation; and primary energy consumption priority, which prioritizes reducing the consumption of primary energy required for equipment operation. In this embodiment, the user can select one of these three optimization targets. If the user selects cost priority, operation control that prioritizes cost reduction is performed, assuming that optimization control is enabled. If the user selects carbon dioxide emission priority, operation control that prioritizes reducing carbon dioxide emissions is performed, assuming that optimization control is enabled. If the user selects primary energy consumption priority, operation control that prioritizes reducing primary energy consumption is performed, assuming that optimization control is enabled.

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

[0038] As can be seen from the above explanation, the display device 13 can switch between multiple types of screens to display information managed by the management system 100. In the example shown in Fig. 4, the display device 13 can switch between 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] 4, menu area 400 includes a forward button 406. When forward button 406 is operated by touching or the like, the type of button for selecting the screen type displayed in menu area 400 is switched. That is, in the example shown in FIG. 4, it is possible to display screens other than the five types of screens, namely, 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-mentioned five types include a user management screen for inputting user information and a screen setting screen for setting conditions related to the screen.

[0040] 4, the home screen 132 also has a footer area 300. The footer area 300 includes an icon area 301 that indicates the user name and a time information area 302 that includes the date and time. In this embodiment, when the icon area 301 is operated by touching or the like, logout can be performed. In a preferred configuration, when the icon area 301 is operated, a confirmation screen pops up on the screen to confirm whether or not to perform logout, and if logout is permitted on the confirmation screen, logout is performed.

[0041] In the present embodiment, as a preferred embodiment, the various screens selectable by the menu area 400, such as the home screen 132, further include a control status display area 500 that indicates the control status of the management system 100. With this configuration, the user can simultaneously obtain information about the control status of the management system 100 on a screen on which the user can grasp various types of information. In other words, user convenience can be improved.

[0042] In the embodiment, the control status display area 500 is included in the header area 200. More specifically, it is located immediately to the right of the menu area 400. However, the position of the control status display area 500 may be changed as appropriate. In the example shown in FIG. 4, "optimized" is displayed in the control status display area 500. This indicates that the management system 100 is operating under the above-mentioned optimization control. In addition to this, the control status display area 500 may also display, for example, "demand control" or "stopped."

[0043] (3-2. Operation settings screen) [3-2-1. Overview of the operation setting screen] 5 is a schematic diagram showing a state in which an 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 touching an operation setting button 405 displayed in the menu area 400.

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

[0045] In this 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) is displayed, a specific button from among the plurality of buttons 411a to 411e displayed in the submenu area 410 is automatically selected, and a screen corresponding to the selected button is displayed. Which button is designated as the specific button may be determined as appropriate. For example, if 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 settings is displayed.

[0046] Meanwhile, the energy demand in the management system 100 is not necessarily the same every day, but usually fluctuates. On the other hand, the daily energy demand tends to be similar if the type of day is the same. In light of this, in this embodiment, the management system 100 is configured to use one of a plurality of setting patterns classified according to the type of day for daily operation. That is, the management system 100 has a plurality of setting patterns. The types of days include, for example, each day of the week that makes up a week, holidays, weekdays, etc. In this embodiment, the display device 13 is configured to display a setting screen (operation setting screen) 133 that can switch between and display a plurality of setting patterns for each pattern.

[0047] With this configuration, the daily operation settings of the management system 100 can be determined by selecting one of a plurality of setting patterns, thereby reducing the burden of setting up the operation of the management system 100 and enabling the management system 100 to be operated appropriately. Furthermore, each of the plurality of setting patterns can be displayed on a separate screen, making it easier to check and input information for each setting pattern.

[0048] 5, the operation setting screen 133 has a tab area 420 below the submenu area 410. The tab area 420 displays ten setting pattern tabs 421: "Mon," "Tue," "Wed," "Thu," "Fri," "Sat," "Sun," "Holiday," "Special Day (1)," and "Special Day (2)." "Mon," "Tue," "Wed," "Thu," "Fri," "Sat," and "Sun" each represent a day of the week. For example, "Mon" refers to Monday.

[0049] Of the ten setting pattern tabs 421, when the Monday tab is selected, the Monday pattern is displayed. When the Tuesday tab is selected, the Tuesday pattern is displayed. When the Wednesday tab is selected, the Wednesday pattern is displayed. When the Thursday tab is selected, the Thursday pattern is displayed. When the Friday tab is selected, the Friday pattern is displayed. When the Saturday tab is selected, the Saturday pattern is displayed. When the Sunday tab is selected, the Sunday pattern is displayed. When the holiday tab is selected, the holiday pattern is displayed. When the special day (1) tab is selected, the special day (1) pattern is displayed. When the special day (2) tab is selected, the special day (2) pattern is displayed. Note that Figure 5 shows the screen when the special day (2) tab is selected.

[0050] That is, in this embodiment, 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 to the daily operation of the management system 100.

[0051] 5, a load button 411a and a fee button 411b are displayed in the submenu area 410 of the operation setting screen 133. As can be seen from this, in this embodiment, the operation settings include load settings, which are settings related to the load, and fee settings, which are settings related to the fee. In other words, the setting pattern specifically includes a load setting pattern and a fee setting pattern.

[0052] The load includes at least one of an electric power load and a heat load. The heat load includes at least one of a heat load and a cold load. In this embodiment, the load includes an electric power load, a heat load, and a cold load.

[0053] When the load button 411a is operated by touching or the like, a load setting screen is displayed. The screen 133 shown in Fig. 5 is the load setting screen. That is, Fig. 5 can also be expressed 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. Furthermore, when the fee button 411b is operated by touching or the like, a fee setting screen is displayed. That is, the setting screen (operation setting screen) 133 can be switched between displaying a load setting screen and a fee setting screen.

[0054] When the calendar button 411c in the submenu area 410 is operated by touching or the like, a calendar screen is displayed. Details of the calendar screen will be described later. Furthermore, when the operation plan button 411d is operated by touching or the like, an operation plan screen is displayed. The operation plan screen is an input screen that allows the selection of whether the optimization control and demand control described above are enabled or disabled. Furthermore, when the demand control button 411e is operated by touching or the like, a demand control screen is displayed. The demand control screen is an input screen that allows detailed settings of demand control.

[0055] As can be seen from the above, the operation setting screen 133 can be switched to display a load setting screen, a fee setting screen, a calendar screen, an operation plan screen, and a demand control screen. The load setting screen, fee setting screen, and calendar screen will be described in detail below.

[0056] [3-2-2. Load setting screen] The load setting screen displays a set value for at least one of the power load, heating load, and cooling load for each predetermined time period. The predetermined time period may be, for example, every hour. The load set value is a predicted value of the load size.

[0057] As described above, the operation setting screen 133 shown in Fig. 5 is an example of a load setting screen. As shown in Fig. 5, in this embodiment, the load setting screen 133 displays hourly setting values ​​for the power load, heating load, and cooling load. In detail, the load setting screen switches for each load setting pattern and displays hourly setting values ​​for the power load, heating load, and cooling load. Note that the load setting pattern is switched using the setting pattern tab 421 as described above.

[0058] In the example shown in Figure 5, the Special Day (2) tab is selected, and the hourly setting values ​​for the power load, heating load, and cooling load for Special Day (2) are displayed. The screen configuration is the same for each load setting pattern. For this reason, the case where the Special Day (2) tab 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. Setting values ​​are displayed in each cell 1331a of the table 1331. The hatched numbers in the table 1331 represent times displayed in 24-hour format. For example, the hatched number "15" means 3:00 p.m. Setting values ​​for one day (24 hours) are displayed every hour for each of the power load, heating load, and cooling load.

[0060] In the example shown in FIG. 5, a graph 1332 is displayed below a table 1331. The horizontal axis of the graph 1332 represents time, with the left end representing midnight and the right end representing midnight. The vertical axis of the graph 1332 represents the amount of load displayed in kilowatts. The graph 1332 is a graph of the setting values ​​displayed in the table 1331. Displaying the graph 1332 in addition to the table 1331 makes it easier to understand how the setting values ​​of each load change over time.

[0061] The load setting screen 133 is a screen on which a load setting value can be manually input. For example, if a user wishes to modify the load setting value, the user can easily modify the setting value. Note that manual input of the load setting value may be used immediately after the management system 100 is introduced. After the initial setting value is input, the control device 11 may be configured to automatically determine the setting value in accordance with operational performance. The value automatically set by the control device 11 may be manually modified by the user.

[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 manually inputting a set value for each of the power load, heating load, and cooling load, the user selects, by touching or the like, a cell 1331a into which the user wants to input a set value. In this case, the user may select one cell 1331a or multiple cells 1331a. With the cell 1331a selected, the user inputs a value to be set in the input value area 1333. After inputting a value into the input value area 1333, the user operates, by touching or the like, an apply button 1334 displayed next to the input value area 1333. This displays the value input in the input value area 1333 for the selected cell 1331a. Note that the selection of the cell 1331a can be deselected by operating, by touching or the like, a deselect button 1335 displayed to the right of the apply button 1334. After completing the input of values ​​into each cell 1331a, the user can confirm the values ​​input into each cell 1331a by moving away from the deselect button 1335 and operating the apply button 1336 on the right side by touching or otherwise operating it.

[0063] In this embodiment, a check box 1331b is displayed at the left end of each of the three load columns shown in the table 1331. When the check box 1331b is operated by touching or the like, a check mark (not shown) is placed in the check box 1331b, and all the cells 1331a for the corresponding load are selected. In other words, by using the check box 1331b, values ​​can be entered collectively into all the cells 1331a for the checked loads. This is convenient, for example, when you want to enter the same value multiple times.

[0064] In this embodiment, a batch button 422 is provided on the right end 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 when any of the setting pattern tabs 421 is selected (see FIG. 5). However, when the batch button 422 is selected, the values ​​of each cell 1331a in the table 1331 are left blank, as shown in FIG. 6. The user can perform load settings for all load setting patterns (10 patterns in this embodiment, as described above) collectively by performing operations such as entering values ​​in the input value area 1333 on the screen 133a displayed by selecting the batch button 422, as described above with reference to FIG. 5.

[0065] That is, the load setting screen 133 displays a collective button 422 that displays a screen 133a that allows manual input of load setting values ​​for multiple setting patterns (more specifically, load setting patterns) all at once. Note that, when the load setting targets are three types (electrical power load, heating load, and cooling load) as in this embodiment, a configuration may be adopted in which all load setting patterns can be set all at once for all or more of these three types. As another example, a configuration may be adopted in which all load setting patterns can be set separately for the three types all at once.

[0066] [3-2-3. Pricing screen] The fee setting screen displays the set value for the energy fee required to operate the equipment owned by the management system 100 for each predetermined time period. Note that each predetermined time period is, for example, every hour. The energy fee includes, for example, electricity fee and gas fee.

[0067] FIG. 7 is a schematic diagram showing a state in which the price setting screen 133b is displayed on the screen 130 of the display device 13. The price setting screen 133b is displayed by selecting the price button 411b displayed in the submenu area 410. As shown in FIG. 7, in this embodiment, the price setting screen 133b displays hourly setting values ​​for electricity, gas, and gas for cogeneration. In detail, the price setting screen 133b switches for each price setting pattern and displays hourly setting values ​​for electricity, gas, and gas for cogeneration. The price setting pattern is switched using the setting pattern tab 421 as described above.

[0068] In the example shown in Figure 7, the Special Day (2) tab is selected, and the hourly set values ​​for electricity, gas, and cogeneration gas for Special Day (2) are displayed. The screen configuration is the same for each rate setting pattern. For this reason, the case where the Special Day (2) tab is selected will be explained as a representative example.

[0069] As shown in Fig. 7, table 1331X is displayed below tab area 420 on fee setting screen 133b. Setting values ​​are displayed in each cell 1331Xa of table 1331X. Note that hatched numbers in table 1331X represent times displayed in 24-hour format. Setting values ​​for one day (24 hours) are displayed every hour for each of electricity, gas, and gas for cogeneration.

[0070] In the example shown in FIG. 7, graph 1332X is displayed below table 1331X. The horizontal axis of graph 1332X represents time, with the left end being midnight and the right end being midnight. The vertical axis of graph 1332X represents fee. In the example shown in FIG. 7, the fee is measured in yen. Graph 1332X is a graph of the setting values ​​displayed in table 1331X. By displaying graph 1332X in addition to table 1331X, it is possible to easily grasp how the setting values ​​of each fee change over time.

[0071] The fee setting screen 133b is a screen on which a fee setting value can be manually input. For example, if a user wants to modify a fee setting value, the user can easily modify the setting value. In this embodiment, the setting value can be manually input 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 to be a screen on which a setting value can be manually input.

[0072] The procedure for inputting setting values ​​using the input value area 1333X, the reflect button 1334X, the deselect button 1335X, and the apply button 1336X is the same as in the case of the load setting screen 133, and therefore will not be described here. Also, in the fee setting screen 133b, as in the case of the load setting screen 133, values ​​can be input collectively into all cells 1331Xa for the fees of checked items using the check boxes 1331Xb.

[0073] Also, in the fee setting screen 133b, as in 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, it is possible to set fees for all fee setting patterns (10 patterns as described above in this embodiment) all at once. In other words, the fee setting screen 133b displays the batch button 422, which displays a screen that allows manual input of fee setting values ​​for multiple setting patterns (more specifically, fee setting patterns) all at once.

[0074] In addition, when there are three types of targets for which pricing is to be set as in this embodiment, the configuration may be such that all of the pricing patterns for all or a plurality of these three types can be set together in one go. As another example, the configuration may be such that all of the pricing patterns for the three types can be set together in one go.

[0075] In addition, in this embodiment, the all-at-once 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 all-at-once button.

[0076] In this embodiment, the fee setting screen 133b displays a season selection button 1337 for selecting between a summer screen and a winter screen, taking into consideration that electricity and gas fee settings may change depending on the season.

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

[0078] In this embodiment, the fee setting screen 133b further displays period setting buttons 423 for setting the summer period and the winter period.

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

[0080] In the example shown in FIG. 8, a summer period can be set for electricity. Periods other than the summer period are considered to be winter periods. In addition, a winter period can be set for gas and gas for cogeneration. Periods other than the winter period are considered to be summer periods. After a period is entered in the period input field 1330 for each item, the set period is confirmed when the apply button 1336Y is operated by touching or the like. The electricity and gas rates used to calculate the planned values ​​for optimization control are determined according to the set period setting.

[0081] It should be noted that for electricity, it may be possible to set a winter period instead of a summer period. Also, for gas (including gas for cogeneration), it may be possible to set a summer period instead of a winter period. It is also possible to configure that the summer period and the winter period can be set separately for electricity and gas (including gas for cogeneration). However, as in this embodiment, it is more difficult to make an error in 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] Display device 13 further displays a calendar screen that allows the user to set, using a calendar, which of a plurality of setting patterns to apply to each day. That is, display device 13 further displays a calendar screen that allows the user to set, using a calendar, which of a plurality of setting patterns to apply to a given day. In this embodiment, the plurality of setting patterns are configured with 10 types of setting patterns as described above.

[0083] 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. The calendar screen 133d is displayed when the calendar button 411c displayed in the submenu area 410 on the operation setting screen 133 is selected.

[0084] 9, calendar screen 133d displays first calendar 1338a and second calendar 1338b. Second calendar 1338b is the calendar for the month following first calendar 1338a. The calendar displayed on calendar screen 133d can be changed by touching or otherwise operating month return button 601 located to the left of first calendar 1338a and month forward button 602 located to the right of second calendar 1338b.

[0085] 9, first calendar 1338a is a calendar for February, and second calendar 1338b is a calendar for March. When month back button 601 is operated by touching or the like, first calendar 1338a becomes a calendar for January, and second calendar 1338b becomes a calendar for February. When month forward button 602 is operated by touching or the like, first calendar 1338a becomes a calendar for March, and second calendar 1338b becomes a calendar for April. Note that the number of calendars displayed on calendar screen 133d may be one, or three or more. Furthermore, the unit of months changed by month back button 601 and month forward button 602 may be two months instead of one month.

[0086] As shown in FIG. 9, the calendar screen 133d displays four buttons to the right of the second calendar 1338b, positioned further away from the month forward 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. A cancel selection button 1335Y is also displayed in the upper left of the first calendar 1338a. These six buttons 1335Y, 1336Z, and 1339a to 1339d are used to determine the setting pattern to be applied to each date. The arrangement of these six buttons 1335Y, 1336Z, and 1339a to 1339d may be changed as appropriate.

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

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

[0089] 9, for example, on February 3rd, the pattern for Monday, which is the day of the week to which that date belongs (Monday pattern), is applied as the set pattern. For example, on February 24th, the holiday pattern is applied as the set pattern, not the pattern for Monday, which is the day of the week to which that date belongs.

[0090] 10A and 10B are diagrams for explaining the procedure for setting one of the setting patterns for each day using calendar screen 133d. In detail, Fig. 10A is a diagram during the setting process, and Fig. 10B is a diagram after the setting has been made.

[0091] The user first selects, by touching or otherwise, the calendar cell 1338c of the date they wish to set. At this time, the user may select only one calendar cell 1338c, or may select multiple calendar cells 1338c. In FIG. 10A, the user has selected multiple calendar cells 1338c. Note that in FIG. 10A, the selected calendar cells 1338c are indicated by dashed frames. In detail, for February, calendar cells 1338c for dates belonging to Mondays except for the 24th are selected, and for March, calendar cells 1338c for dates belonging to Mondays are selected. Note that the selection can be canceled by operating the cancel selection button 1335Y.

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

[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 a Holiday, and the Holiday setting pattern will be applied to the date displayed as a Holiday. 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 Special Day (2), and the Special Day (2) setting pattern will be applied to the date displayed as Special Day (2).

[0094] The Cancel button 1339d is a button for canceling setting patterns that are specially provided apart from days of the week, such as the Holiday pattern, Special Day (1) pattern, and Special Day (2) pattern. For this reason, in the example described above, if the Cancel button 1339d is selected instead of the Special Day (1) button 1339b, the selection of the selected calendar cell 1338c is cancelled without changing the display. For example, if the Cancel button 1339d is selected while the calendar cell 1338c for February 24 is selected, the calendar cell 1338c for February 24 will be displayed with a white background against a black number. Then, for February 24, the pattern for Monday (Monday pattern), the day of the week to which that date belongs, will be applied as the setting pattern.

[0095] [3-2-5. Modifications] FIG. 11 is a schematic diagram showing a load setting screen 133X of a modified 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 settings for the next day. In detail, it is assumed that the next day is estimated to be the day when the special day (2) pattern should be applied, and the special day (2) tab is selected in the setting pattern tab 421. The load setting screen 133X shown in FIG. 11 differs from the example shown in FIG. 5 in that an estimation reason button 424 is displayed in the tab area 420.

[0096] In a modified example, the management system 100 is configured to be able to estimate at least the setting pattern to be applied the next day. In a preferred embodiment, the management system 100 is configured to be able to estimate at least the load setting pattern to be applied the next day. In this embodiment, the load setting pattern obtained by estimation is one of the 10 types of patterns described above. It may be configured to estimate only the load setting pattern for the next day, or it may be configured to estimate the set load setting pattern to be applied for multiple days from the next day onwards. The load setting pattern to be applied is estimated by the control device 11.

[0097] The above-mentioned inferred reason button 424 is a button for displaying the inferred reason for the setting pattern to be applied (the load setting pattern in this example). When the inferred reason button 424 is operated by touching or the like, an inferred reason display screen showing the inferred reason is displayed. That is, the display device of the modified example further displays an inferred reason display screen showing the inferred reason for the setting pattern (the load setting pattern in this example).

[0098] Fig. 12 is a schematic diagram showing a state in which an inferred reason display screen 133X1 is displayed on the screen 130 of a display device of a modified example. The inferred reason display screen 133X1 shown in Fig. 12 is a screen displayed when the inferred reason button 424 is selected on the screen 133X shown in Fig. 11. As shown in Fig. 12, the inferred reason display screen 133X1 includes an inferred reason display area Ar that displays the inferred reason, and a graph area Gr that displays a graph related to the inferred reason. In this modified example, the inferred reason display area Ar is a part that explains the inferred reason using text. The graph area Gr is an area that displays, for example, a graph or the like that shows the basis of the inferred reason.

[0099] In the example shown in FIG. 12 , the horizontal axis of the graph shown in the graph area Gr represents the maximum temperature of the day, and the vertical axis represents the maximum cooling / heating load. The graph shown in FIG. 12 plots actual values ​​for multiple past days. The graph also shows the results of grouping the past actual values ​​using a grouping algorithm, such as artificial intelligence (AI). Specifically, the grouping is based on whether the day corresponds to a special day (2) (e.g., a busy day). Days that could not be determined to be special days (2) are classified as undeterminable. According to the graph, whether a day's maximum temperature exceeds 29°C can be determined to be a special day (2). In the example shown in FIG. 12 , the next day's maximum temperature is predicted to be 35°C. Based on the determination method using the threshold value of 29°C based on the graph, the next day is estimated to be a special day (2). The estimation reason display area Ar displays the setting pattern as the special day (2) pattern. The provision of the graph area Gr makes it easier for the user to determine the validity of the estimation reason.

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

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

[0102] <4. Things to keep in mind> Various modifications can be made to the various technical features disclosed in this specification without departing from the spirit of the technical creation. Furthermore, multiple embodiments and modifications shown in this specification can be combined to the extent possible. [Explanation of symbols]
