[0009] Hereinafter, a display control system according to one embodiment of this disclosure will be described with reference to the drawings. Before describing the display control system, a power generation system including the display control system according to this embodiment will be described first.

[0010] Figure 1 is a schematic block diagram showing the system configuration of a power generation system 1 according to an embodiment. As shown in Figure 1, the power generation system 1 includes a power generation facility 10, an EMS 20 (Energy management system), and a display and control system 30. The power generation facility 10 and the EMS 20, and the EMS 20 and the display and control system 30 are communicated to each other via a network 70. The network 70 may be a wireless communication network or a wired communication network. The network 70 may be configured using, for example, the Internet, or a local area network (LAN). The network 70 may be configured by combining multiple networks.

[0011] The power generation facility 10 is, for example, a known facility. The power generation facility 10 may be, for example, a power plant, or it may be a facility that generates electricity secondarily by utilizing energy generated inside the plant. In this embodiment, the power generation facility 10 generates electricity using renewable energy or depletable energy. Renewable energy includes, for example, solar power, wind power, geothermal energy, and biomass. Depletable energy includes, for example, fossil fuels. In this embodiment, the electricity generated by the power generation facility 10 is charged into a battery provided by the power generation facility 10. The electricity charged into the battery may be discharged as needed.

[0012] The EMS20 is a system that manages the operating status of the power generation facility 10. In this embodiment, the EMS20 communicates with the power generation facility 10 via the network 70 to manage the charge and discharge amount of the battery installed in the power generation facility 10 and the intensity of the battery degradation suppression.

[0013] The display control system 30 acquires information about the power generation facility 10 by communicating with the EMS 20 via the network 70. The display control system 30 then displays the information acquired from the power generation facility 10, as well as other information necessary for the operation of the EMS 20. The user of the power generation system 1 determines the operational policy of the EMS 20 by understanding the various information displayed by the display control system 30. Hereinafter, the user of the power generation system 1 will be simply referred to as the user.

[0014] In this power generation facility 10, the ratio of electricity generated from renewable energy to electricity generated from depletable energy sources changes depending on the time of day. At this time, electricity derived from renewable energy sources has a relatively high value, while electricity derived from depletable energy sources has a relatively low value. Furthermore, a fast charging and discharging rate in a battery accelerates its degradation. A slow charging and discharging rate in a battery suppresses its degradation. Hereinafter, the charging and discharging rate in a battery may be referred to as the C rate. In this embodiment, the C rate may represent the time it takes for the battery to be charged to its maximum capacity, or the time it takes for the battery to be completely discharged. In this embodiment, the magnitude of the current required to completely charge or discharge the battery in one hour is defined as 1C.

[0015] In this embodiment, the user understands, for example, the ratio of electricity generated from renewable energy to electricity generated from non-renewable energy, the degradation rate of the storage battery, the C-rate, etc., from various information displayed by the display control system 30. The user then sets the charge and discharge amount of the storage battery and the intensity of suppression of storage battery degradation in a way that can increase profitability. In this way, the user determines the operational policy of the EMS 20.

[0016] Figure 2 is a schematic block diagram showing a specific example of the functional configuration of the display control system 30. The display control system 30 is configured using an information device such as a smartphone, a tablet, a personal computer, or a dedicated device, for example. The display control system 30 includes a communication unit 31, an input unit 32, a display unit 33, a storage unit 34, and a control unit 35.

[0017] The communication unit 31 is a communication device. The communication unit 31 may be configured as a network interface, for example. The communication unit 31 performs data communication with other devices via the network 70 under the control of the control unit 35. The communication unit 31 may be a device that performs wireless communication or a device that performs wired communication.

[0018] The input unit 32 is configured using an existing input device such as a keyboard, a pointing device (such as a mouse or a tablet), a button, or a touch panel. The input unit 32 is operated by a user when the user inputs an instruction to the display control system 30. The input unit 32 may be an interface for connecting an input device to the display control system 30. In this case, the input unit 32 inputs, to the display control system 30, an input signal generated according to a user's input in the input device. The input unit 32 may be configured using a microphone and a voice recognition device. In this case, the input unit 32 acquires an acoustic signal generated by a user's utterance, performs voice recognition on the wording uttered by the user, and inputs character string information of a recognition result to the display control system 30. The voice recognition process may be executed by the control unit 35. The input unit 32 may be configured in any manner as long as it can input a user's instruction to the display control system 30.

[0019] The display unit 33 outputs information in a form recognizable to a user. The display unit 33 may be, for example, an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 33 may be an interface for connecting an image display device to the display control system 30. In this case, the display unit 33 generates a video signal for displaying image data, and outputs the video signal to the image display device connected thereto. Note that the display unit 33 may be configured as a touch panel integrated with the input unit 32.

[0020] The storage unit 34 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 34 stores data used by the control unit 35. The storage unit 34 stores data required when the control unit 35 performs processing.

[0021] The control unit 35 is configured using a processor such as a CPU (Central Processing Unit) and a memory (main storage device). The control unit 35 functions as a display control means 351, a selection means 352, a change means 353, and a calculation means 354 when the processor executes a program. Note that all or part of the functions of the control unit 35 may be implemented using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded in a computer-readable recording medium. Examples of the computer-readable recording medium include portable media such as flexible disks, magneto-optical disks, ROMs, CD-ROMs, and semiconductor storage devices (e.g., SSD: Solid State Drive), and storage devices such as hard disks and semiconductor storage devices built into a computer system. The above program may be transmitted via a telecommunication line.

[0022] The control unit 35 may, for example, execute an application installed on its own device (display control system 30). A program installed on the display control system 30 may cause the computer to function as the display control system 30 according to this embodiment. A specific example of such an application is an application provided to the display control system 30 as a dedicated application for the display control system 30. Another specific example of such an application is a web browser application. Such an application may be pre-installed on the display control system 30, or it may be downloaded each time a determination process is executed. For example, if it is implemented as a web browser application, the display control system 30 may download and execute the application from a device specified by the web server (for example, the web server itself or another server) when the display control system 30 connects to a specific web server. The control unit 35 operates according to the program of the application being executed.

[0023] The display control means 351 causes various types of information to be displayed on the display unit 33. In this embodiment, the information displayed on the display unit 33 by the display control means 351 includes intensity information, power consumption information, time period information, degradation degree information, period information, revenue information, C-rate information, maximum value information, and renewable energy information. As will be described later, the display control means 351 may display each of these types of information as an image on the display unit 33. The following explains the specific contents of this information.

[0024] The intensity information indicates the intensity at which battery degradation is suppressed by the EMS20. Hereinafter, the intensity at which battery degradation is suppressed will be referred to as the degradation suppression intensity. In this embodiment, the degradation suppression intensity is indicated by, for example, a level. In this embodiment, the degradation suppression intensity level may be indicated by, for example, an integer. Specifically, when the numerical value of the degradation suppression intensity level is 0, no degradation of the battery is suppressed by the EMS20. The degradation suppression intensity increases as the numerical value of the degradation suppression intensity level increases.

[0025] The degradation rate of a storage battery varies depending on factors such as the C-rate, SOC level, and temperature. Therefore, in this embodiment, the degradation suppression strength may correspond to any one of the C-rate, SOC level, or temperature. If the degradation suppression strength corresponds to the C rate, then an increase in degradation suppression strength indicates a decrease in the C rate. As mentioned above, a fast charge-discharge rate in a battery accelerates battery degradation. A slow charge-discharge rate in a battery suppresses battery degradation. Therefore, in order to suppress battery degradation, it is preferable to lower the C rate using EMS20 and slow down the charge-discharge rate in the battery. When the degradation suppression intensity corresponds to the SOC level (State of Charge level), that is, when the degradation suppression intensity corresponds to the charge level of the battery, an increase in the degradation suppression intensity indicates a decrease in the charge level of the battery. In a battery, a high charge level accelerates battery degradation. In a battery, a low charge level suppresses battery degradation. Therefore, in order to suppress battery degradation, it is preferable to reduce the charge level of the battery using the EMS20. Reducing the charge level of the battery may include, for example, not only simply reducing the charge level of the battery, but also shortening the time that the battery is in a high charge state. If the degradation suppression strength corresponds to temperature, an increase in degradation suppression strength indicates a decrease in the battery temperature. High battery temperatures accelerate battery degradation. Low battery temperatures suppress battery degradation. Therefore, to suppress battery degradation, it is preferable to lower the battery temperature using the EMS20. To lower the battery temperature, the power generation facility 10 may be equipped with cooling equipment (not shown). In this embodiment, the intensity information may be one of the following: one corresponding to the C-rate of the battery, one corresponding to the SOC level of the battery, and one corresponding to the temperature of the battery. That is, the degradation suppression intensity may be determined based on one of the above. Alternatively, the degradation suppression intensity may be determined based on a combination of the above, or on all of the above.

[0026] The power quantity information indicates the amount of power that the EMS20 uses to discharge the battery at the intensity indicated by the intensity information. In other words, the power quantity information is, for example, the amount of power that discharges the battery corresponding to the battery degradation suppression intensity by the EMS20. The power quantity information may also indicate the amount of power that discharges the battery and the amount of power that charges the battery. In this embodiment, the amount of energy may be the amount of energy corresponding to an arbitrarily determined time period, or it may be the amount of energy per unit time. In this embodiment, the length of the unit time may be set to every 30 minutes, every 1 hour, or any other arbitrary length.

[0027] Time zone information is information indicating the time period during which electricity is discharged from the storage battery. In this embodiment, the time zone information includes first time zone information and second time zone information. The first time zone information indicates the first time period during which electricity is discharged from the battery. The second time zone information indicates the second time period during which electricity is discharged from the battery. In this embodiment, the length of time represented by the first time zone and the second time zone may be set arbitrarily. For example, the length of time may be set in 30-minute intervals, in 1-hour intervals, or for any other arbitrary length. In this embodiment, the first time zone and the second time zone may be different time zones. Also, the first time zone and the second time zone may have different lengths. Furthermore, in this embodiment, the time zone information may include a third time zone and a fourth time zone, in addition to the first and second time zones, or it may include a fifth time zone and beyond.

[0028] The degradation level information indicates the degree to which the battery degrades, corresponding to the intensity level indicated by the intensity information. In other words, the degradation level information represents the degree of battery degradation corresponding to the degradation suppression intensity of the battery by EMS20. The degree of battery degradation can be indicated, for example, by the State of Health (SOH). SOH can be expressed as, for example, the percentage of the battery's full charge capacity after degradation compared to its initial full charge capacity (which is set at 100%), or as the change in full charge capacity from the initial state to the degraded state. For example, if the battery's full charge capacity falls to 80% of its initial capacity, this can be expressed as a 20% degradation of the battery. In this embodiment, the degradation degree information may indicate, for example, the degree to which the battery degrades at the intensity indicated by the intensity information and the amount of energy indicated by the energy information. That is, the degradation degree information may indicate the degree to which the battery degrades per unit time, which is assumed to occur when the battery is used at the amount of energy used to charge and discharge the battery, corresponding to the degradation suppression intensity of the battery by the EMS20. In this embodiment, the length of the unit time may be set to every 30 minutes, every 1 hour, or any other arbitrary length. Furthermore, the degradation degree information may indicate, for example, the degree to which the battery degrades over a period of time that corresponds to the intensity indicated by the intensity information and the period indicated by the period information described later. In other words, the degradation degree information may indicate the degree to which the battery degrades after a period of time that is expected when the battery is used with an amount of power to charge and discharge the battery corresponding to the degradation suppression intensity of the battery by the EMS20, for an arbitrarily determined period. In this embodiment, the degree of deterioration information includes first degree of deterioration information and second degree of deterioration information. The first degradation level information is the degradation level information for the first time period, which is the time period during which discharge occurs. The second degradation level information is the degradation level information for the second time period, which is the time period during which discharge occurs.

[0029] The period information indicates the period over which the battery is discharged. In this embodiment, the length of time indicated by the period information may be set arbitrarily. For example, the length of time indicated by the period information may be set on a daily basis, on a weekly basis, on a monthly basis, on a yearly basis, or on any other arbitrary period. Alternatively, the unit time may be set to the same unit time used in the degradation degree information to indicate the degree to which the battery degrades.

[0030] The revenue information is information that indicates the revenue corresponding to the amount of electricity discharged from the battery, and represents the revenue from the EMS20. In this embodiment, the revenue from the EMS20 is the revenue from selling the electricity discharged from the battery. In this embodiment, revenue information includes first revenue information and second revenue information. The first revenue information shows the revenue during the first time period, which is the period when the discharge occurs. The second revenue information shows the revenue during the second time period, which is the period when the discharge occurs.

[0031] C-rate information is information indicating the C-rate of the storage battery. As mentioned above, the C-rate is information indicating the charge and discharge speed of the storage battery. In this embodiment, the C-rate of the storage battery may be changed as appropriate by the EMS20.

[0032] The maximum value information indicates the maximum charge / discharge amount of the battery. As described above, a high charge amount in the battery accelerates battery degradation, while a low charge amount suppresses battery degradation. In this embodiment, the maximum charge / discharge amount of the battery is the maximum SOC level, set considering the balance between the battery degradation rate and the revenue generated from selling the electricity discharged from the battery, based on the aforementioned relationship. In this embodiment, the maximum charge / discharge amount of the battery may be changed as appropriate by the EMS20.

[0033] Renewable energy information indicates whether or not the electricity discharged from the battery originates from renewable energy sources. This renewable energy information may be expressed as a percentage (%) or other ratio. In this embodiment, the display control means 351 may convert the various types of information described above into information that can be visually viewed by the user as appropriate and display it on the display unit 33.

[0034] The selection means 352 is a means for selecting whether to associate the intensity information with the C rate, the SOC level, or the temperature. In this embodiment, associating the intensity information with any of these means, for example, determining the degradation suppression intensity based on any of these. The selection means 352 may, based on user instructions, determine whether to associate the degradation suppression intensity related to the intensity information with C-rate, SOC level, or temperature. The user may determine the degradation suppression intensity related to the intensity information to be one of these by appropriately inputting instructions, for example, via the input unit 32. The user interface of the selection means 352 may be displayed on the display unit 33 as appropriate. Details of the user interface of the selection means 352 will be described later.

[0035] The modification means 353 is a means for changing the intensity information. The modification means 353 may determine the degradation suppression intensity based on user instructions. As described above, in this embodiment, the degradation suppression intensity is indicated by a level. The user may appropriately set the level of the degradation suppression intensity related to the intensity information by appropriately inputting instructions via the input unit 32, for example. The user interface of the modification means 353 may be displayed on the display unit 33 as appropriate. Details of the user interface of the modification means 353 will be described later.

[0036] The calculation means 354 is a means for calculating the various information mentioned above that is displayed by the display control means 351, based on various information regarding the state of the storage battery and the contents set or changed by the selection means 352 and the change means 353. In this embodiment, the calculation processing by the calculation means 354 may be performed at any time while the display control system 30 is in operation. In addition, the various information used in the calculations of the calculation means 354 may be stored in the storage unit 34, in addition to being displayed on the display unit 33 by the display control means 351. The display control system 30 according to this embodiment is configured with the above-described components.

[0037] (Display control method) Next, the display control method according to this embodiment will be described. Figure 3 shows a flowchart of the display control method according to the embodiment. As shown in Figure 3, the display control method according to this embodiment comprises an information processing step S1, a display control step S2, and a confirmation step S3.

[0038] Information processing step S1 is a step in which the display control system 30 communicates with the EMS 20 via the communication unit 31. In information processing step S1, the display control system 30 obtains information from the EMS 20, for example, such as the power generation status of the power generation facility 10 and the status of the storage battery. In addition, in information processing step S1, the display control system 30 may appropriately transmit to the EMS 20 content corresponding to the intensity information set by the selection means 352 and information on the degradation suppression intensity set by the modification means 353. Furthermore, in the information processing step S1, the calculation means 354 may calculate various information to be displayed on the display unit 33 in the display control step S2. The various information calculated in this way, as well as the various conditions obtained from the EMS 20, may be stored in the storage unit 34 in the information processing step S1.

[0039] Display control step S2 is a step in which the display control means 351 in the display control system 30 causes various information to be displayed on the display unit 33. Figure 4 shows an example of a screen displayed on the display unit 33 by the display control step S2. In the example shown in Figure 4, the display unit 33 displays the information table I1, the period image I2, the selected image I3, and the changed image I4.

[0040] Information Table I1 organizes and displays the various pieces of information mentioned above. In the example shown in Figure 4, Information Table I1 is displayed at the top of the screen of the display unit 33, but it may be displayed in any other location. Information Table I1 displays the time period image G1, the intensity image G2, the power consumption image G3, the degree of degradation image G4, the revenue image G5, the C-rate image G6, the maximum value image G7, and the renewable energy image G8.

[0041] The time zone image G1 is an image that shows time zone information. In the example shown in Figure 4, the time zone image G1 is displayed in the first row from the top of information table I1. As shown in Figure 4, the leftmost part of the first row from the top of information table I1 may also contain the notation "Time Zone" to indicate that the time zone image G1 is being displayed. As shown in Figure 4, the time-of-day image G1 includes, for example, a first time-of-day image G1a, a second time-of-day image G1b, a third time-of-day image G1c, a fourth time-of-day image G1d, and a fifth time-of-day image G1e. The first time zone image G1a is the image corresponding to the first time zone information. In the example shown in Figure 4, the first time zone image G1a shows 0:00 to 4:00. The second time zone image G1b is the image corresponding to the second time zone information. In the example shown in Figure 4, the second time zone image G1b represents the period from 4:00 to 12:00. The third time zone image G1c is the image corresponding to the third time zone information. In the example shown in Figure 4, the third time zone image G1c represents the period from 12:00 to 16:00. The fourth time zone image G1d is the image corresponding to the fourth time zone information. In the example shown in Figure 4, the fourth time zone image G1d shows 16:00 to 20:00. The fifth time zone image G1e is the image corresponding to the fifth time zone information. In the example shown in Figure 4, the fifth time zone image G1e shows the period from 20:00 to 0:00. Thus, in this embodiment, a day (24 hours) may be divided into five parts by the first to fifth time zones. Depending on the length of the time zones, a day (24 hours) may also be divided into two, three, four, or six or more parts.

[0042] Intensity image G2 is an image that shows intensity information. In the example shown in Figure 4, intensity image G2 is displayed in the second row from the top of information table I1. As shown in Figure 4, the left end of the second row from the top of information table I1 may also contain the notation "Degradation Suppression Intensity" to indicate that intensity image G2 is being displayed. As shown in Figure 4, the intensity image G2 indicates the degradation suppression intensity level, which is the intensity at which battery degradation is suppressed by the EMS20, as an integer. In intensity image G2, it is acceptable to indicate that the degradation suppression intensity level increases as the magnitude of the integer increases. In this embodiment, the display control means 351 may, for example, display the first time period information and the intensity information in correspondence with each other on the display unit 33. That is, as shown in Figure 4, the intensity image G2 corresponding to the first time period may be displayed below the first time period image G1a. In the example shown in Figure 4, the intensity image G2 displayed below the first time period image G1a indicates that the degradation suppression intensity corresponding to the first time period is "Lv.7". Furthermore, the display control means 351 may display the first time period information and the intensity information for the first time period in association with each other on the display unit 33, and may also display the second time period information and the intensity information for the second time period in association with each other on the display unit 33. That is, as shown in Figure 4, in addition to the intensity image G2 corresponding to the first time period being displayed below the first time period image G1a, the intensity image G2 corresponding to the second time period may be displayed below the second time period image G1b. In the example shown in Figure 4, the intensity image G2 displayed below the second time period image G1b indicates that the degradation suppression intensity corresponding to the second time period is "Lv.2". The above display method is the same for the third to fifth time slots, so no further explanation is provided. Thus, the intensity image G2 may be displayed corresponding to each of the time periods divided as described above. In other words, in this embodiment, the degradation suppression intensity may be set corresponding to each of the time periods divided as described above.

[0043] The power consumption image G3 is an image that displays power consumption information. In the example shown in Figure 4, the power consumption image G3 is displayed in the third row from the top of information table I1. As shown in Figure 4, the leftmost part of the third row from the top of information table I1 may also contain the text "Power Consumption" to indicate that the power consumption image G3 is being displayed. As shown in Figure 4, the power quantity image G3 shows, for example, the amount of power used to discharge the battery and / or the amount of power used to charge the battery, in kilowatt-hours (kWh). In this embodiment, for example, the amount of power used to discharge the battery may be shown as a positive (+) value, and the amount of power used to charge the battery may be shown as a negative (-) value. In this embodiment, the display control means 351 displays the intensity information as an intensity image G2 and the power quantity information as a power quantity image G3 on the display unit 33. At this time, the display control means 351 may display the intensity information and the power quantity information on the display unit 33 in correspondence with each other. In other words, in this embodiment, the display control step S2 can be said to be a step of displaying on the display unit 33 intensity information indicating the intensity at which battery degradation is suppressed by the EMS 20, and power quantity information indicating the amount of power that the EMS 20 discharges from the battery at the intensity indicated by the intensity information. Furthermore, in the display control step S2, images corresponding to the various types of information described below may be displayed on the display unit 33. In this embodiment, the amount of energy displayed by the energy quantity image G3 may be a numerical value corresponding to the degradation suppression intensity level shown by the intensity image G2. Also, similar to the intensity image G2, the energy quantity image G3 may be displayed corresponding to each of the time periods divided as described above. In the example shown in Figure 4, the energy quantity image G3 displayed below the first time period image G1a indicates that the amount of energy (amount of energy discharged) corresponding to the first time period is "+100kWh". The above display method is the same for the second to fifth time periods, so the explanation is omitted. In other words, in this embodiment, the amount of energy may be displayed corresponding to each of the time periods divided as described above.

[0044] The degradation level image G4 is an image that shows information about the degree of degradation. In the example shown in Figure 4, the degradation level image G4 is displayed in the fourth row from the top of the information table I1. As shown in Figure 4, the left end of the fourth row from the top of the information table I1 may also contain the notation "Degradation Level" to indicate that the degradation level image G4 is displayed. As shown in Figure 4, the degradation level image G4 displays the degradation level information, for example, in percentage (%). In this embodiment, the display control means 351 may display the degree of deterioration information as a degree of deterioration image G4 on the display unit 33, along with the intensity information and the power consumption information. Furthermore, as shown in Figure 4, the degree of deterioration image G4 may be displayed corresponding to each of the time periods divided as described above. In the example shown in Figure 4, the degradation level image G4 displayed below the first time period image G1a indicates that the degradation level of the battery corresponding to the first time period is "0.1%". This indicates that, for example, if the battery is used with the amount of power corresponding to the first time period, the battery is expected to degrade by 0.1%. The above display method is the same for the second to fifth time periods, so the explanation is omitted. In other words, in this embodiment, the expected degradation level of the battery may be displayed corresponding to each of the time periods divided as described above.

[0045] Revenue image G5 is an image that shows revenue information. In the example shown in Figure 4, revenue image G5 is displayed in the fifth row from the top of information table I1. As shown in Figure 4, the word "Revenue" may be displayed at the left end of the fifth row from the top of information table I1 to indicate that revenue image G5 is being displayed. As shown in Figure 4, revenue image G5 displays revenue information, for example, using circles. In this embodiment, the display control means 351 may display the revenue information as a revenue image G5 on the display unit 33 along with the intensity information and the power consumption information. Also, as shown in Figure 4, the revenue image G5 may be displayed corresponding to each of the time periods divided as described above. In the example shown in Figure 4, the revenue image G5 displayed below the first time period image G1a indicates that the revenue corresponding to the first time period is "28,000 yen". This indicates that if the battery is used with the amount of power corresponding to the first time period, a revenue of 28,000 yen is expected. The above display method is the same for the second to fifth time periods, so the explanation is omitted. In other words, in this embodiment, the expected revenue may be displayed corresponding to each of the time periods divided as described above.

[0046] The C-rate image G6 is an image that shows the C-rate. In the example shown in Figure 4, the C-rate image G6 is displayed in the sixth row from the top of Information Table I1. As shown in Figure 4, the words "C-rate" may be displayed at the left end of the sixth row from the top of Information Table I1 to indicate that the C-rate image G6 is being displayed. As shown in Figure 4, the C-rate image G6 indicates the C-rate, for example, in units of "C". In this embodiment, the display control means 351 may display the C-rate information as the C-rate image G6, together with the intensity information and the power information, on the display unit 33. Also, as shown in Figure 4, the C-rate image G6 may be displayed corresponding to each of the time periods divided as described above. In the example shown in Figure 4, the C-rate image G6 displayed below the first time period image G1a indicates that the C-rate corresponding to the first time period is "0.25C". This indicates that the C-rate in the first time period is a current value of one-quarter of 1C, and that this is a current value that can fully charge or discharge the battery in 4 hours. The above display method is the same for the second to fifth time periods, so the explanation is omitted. In other words, in this embodiment, the C-rate may be displayed corresponding to each of the time periods divided as described above.

[0047] The maximum value image G7 is an image that displays the maximum value information. In the example shown in Figure 4, the maximum value image G7 is displayed in the 7th row from the top of the information table I1. As shown in Figure 4, the words "Maximum Value" may be displayed at the left end of the 7th row from the top of the information table I1 to indicate that the maximum value image G7 is being displayed. As shown in Figure 4, the maximum value image G7 indicates the maximum charge / discharge amount of the set battery, for example, in percent (%). In this embodiment, the display control means 351 may display the maximum value information as a maximum value image G7 on the display unit 33, along with the intensity information and the power consumption information. Also, as shown in Figure 4, the maximum value image G7 may be displayed corresponding to each of the time periods divided as described above. In the example shown in Figure 4, the maximum value image G7 displayed below the first time period image G1a indicates that the maximum charge / discharge amount of the battery corresponding to the first time period is "13.3%". This indicates, for example, that in the first time period, the charge / discharge amount of the battery is set to 13.3% of the battery's full charge capacity. The above display method is the same for the second to fifth time periods, so no explanation is given. In other words, in this embodiment, the maximum charge / discharge amount of the battery may be displayed corresponding to each of the time periods divided as described above.

[0048] The renewable energy image G8 is an image that displays renewable energy information. In the example shown in Figure 4, the renewable energy image G8 is displayed in the 8th row from the top of Information Table I1. As shown in Figure 4, the leftmost column of the 8th row from the top of Information Table I1 may also contain the notation "Renewable Energy Rate" to indicate that the renewable energy image G8 is being displayed. As shown in Figure 4, the renewable energy image G8 indicates, for example, whether the electricity discharged from the battery originates from renewable energy, using a percentage (%). In this embodiment, the display control means 351 may display the renewable energy information as a renewable energy image G8 on the display unit 33 in association with the intensity information. Also, as shown in Figure 4, the renewable energy image G8 may be displayed corresponding to each of the time periods divided as described above. In the example shown in Figure 4, the renewable energy image G8 displayed below the first time period image G1a indicates that the renewable energy information corresponding to the first time period is "20%". This indicates, for example, that 20% of the electricity discharged from the battery during the first time period is derived from renewable energy. The above display method is the same for the second to fifth time periods, so no further explanation is provided. In other words, in this embodiment, whether or not the electricity discharged from the battery is derived from renewable energy may be displayed corresponding to each of the time periods divided as described above. In this embodiment, information table I1 displays the various types of information described above.

[0049] The period image I2 is an image that shows period information. In the example shown in Figure 4, the period image I2 is displayed at the bottom of the screen of the display unit 33, but it may be displayed in any other location. In the example shown in Figure 4, the period image I2 is labeled "September 1, 2024 - September 30, 2024". This indicates that the battery is scheduled to be used in accordance with the amount of power displayed in the information table I1 during the above period. In this embodiment, the display control means 351 may display the period information on the display unit 33 together with the intensity information, power amount information, and degradation degree information. That is, in this embodiment, the period image I2 may be displayed on the display unit 33 together with the information table I1 containing the various types of information mentioned above. In this embodiment, the user may appropriately change the period related to the period information by appropriately inputting the period displayed in the period image I2 using the input unit 32.

[0050] The selection image I3 is the user interface of the selection means 352. That is, the selection image I3 is displayed to allow the user to select whether the intensity information corresponds to the C rate, the SOC level, or the temperature. In the example shown in Figure 4, the selection image I3 is displayed at the bottom of the screen of the display unit 33, but it may be displayed in any other location. In the example shown in Figure 4, the selection image I3 displays "C rate," indicating that the intensity information is set to correspond to the C rate. In this way, the display control means 351 may display on the display unit 33 in a way that makes it possible to determine whether the intensity information corresponds to the C rate, the SOC level, or the temperature. In this embodiment, the selected image I3 may be, for example, a dropdown list. That is, for example, the user may select the selected image I3 by clicking or tapping, thereby setting the intensity information to correspond to one of the contents described above.

[0051] The change image I4 is the user interface of the change means 353. That is, the change image I4 is used by the user to set the level of battery degradation suppression intensity. In the example shown in Figure 4, the period image I2 is displayed at the bottom of the screen of the display unit 33, but it may be displayed in any other location. In the example shown in Figure 4, the change image I4 includes a numerical display I4a and two triangular buttons I4b. The numerical display I4a indicates the current degradation suppression intensity level. In the example shown in Figure 4, the degradation suppression intensity is "Lv.7". Also, in the example shown in Figure 4, the intensity image G2 corresponding to the first time period image G1a is displayed in an inverted color compared to the other intensity images G2. This may indicate that the degradation suppression intensity corresponding to the first time period has been set by the modified image I4. When setting the degradation suppression intensity for any time period, the user may select the intensity image G2 corresponding to the time period to be set by clicking or tapping. The two triangular buttons I4b are displayed on the screen of the display unit 33 such that one of each vertex points in opposite directions. In the example shown in Figure 4, one of the vertices of the two triangular buttons I4b are displayed pointing up and down relative to each other. However, this is not the only option; one of the vertices of the two triangular buttons I4b may also be displayed pointing left and right relative to each other. For example, a user may increase the degradation suppression level by clicking or tapping one of the triangular buttons I4b shown in Figure 4, where one of the vertices is pointing upwards on the screen. Similarly, a user may decrease the degradation suppression level by clicking or tapping one of the triangular buttons I4b shown in Figure 4, where one of the vertices is pointing downwards on the screen.

[0052] Here, as described above, if the degradation suppression strength corresponds to the C rate, then an increase in degradation suppression strength indicates a decrease in the C rate. For this reason, in this embodiment, if the degradation suppression strength corresponds to the C rate, the C rate information may change in accordance with the change by the changing means 353. In other words, the EMS 20 may change the C rate in accordance with the change in degradation suppression strength by the changing means 353. Furthermore, if the degradation suppression intensity corresponds to the SOC level (State of Charge level), an increase in degradation suppression intensity indicates a decrease in the amount of charge in the battery. Therefore, in this embodiment, if the degradation suppression intensity corresponds to the SOC level, the SOC level may change in response to the change by the modification means 353. In other words, the EMS 20 may change the amount of charge in the battery in response to the change in degradation suppression intensity by the modification means 353. Furthermore, in this embodiment, the maximum value information may change in accordance with the changes made by the modification means 353. In other words, the EMS 20 may change the maximum value of the charge / discharge amount of the storage battery in accordance with the change in the degradation suppression intensity made by the modification means 353. Furthermore, if the degradation suppression strength corresponds to temperature, an increase in degradation suppression strength indicates a decrease in the battery temperature. Therefore, in this embodiment, if the degradation suppression strength corresponds to temperature, the battery temperature may change in response to the change by the modification means 353. In other words, the EMS 20 may change the battery temperature in response to the change in degradation suppression strength by the modification means 353. Furthermore, in this embodiment, the power quantity information may change in accordance with the change in degradation suppression intensity by the modification means 353. In other words, the EMS 20 may change the amount of power when charging or discharging the storage battery in accordance with the change in degradation suppression intensity by the modification means 353.

[0053] In the display control step S2, the various information described above may be displayed on the screen of the display unit 33 as needed. As mentioned above, electricity derived from renewable energy sources has relatively high value, while electricity derived from depletable energy sources has relatively low value. In addition, at the power generation facility 10, the ratio of electricity generated from renewable energy sources to electricity generated from depletable energy sources changes depending on the time of day, etc. Users can also understand the ratio of electricity generated from renewable energy sources to electricity generated from depletable energy sources, the degradation rate of the storage battery, the C-rate, etc., by visually checking the various information displayed on the screen of the display unit 33. Users can then set the charge / discharge amount of the storage battery and the degradation suppression intensity of the storage battery to maximize profitability. At this time, in order to make it easier for the user to more accurately set the charge / discharge amount of the storage battery and the degradation suppression intensity of the storage battery, it is preferable that the display control means 351 displays the screen of the display unit 33 as follows in the display control step S2.

[0054] In other words, for example, the display control means 351 may change the display mode of the intensity information according to the amount of electricity generated from renewable energy. Specifically, for example, if the amount of electricity generated from renewable energy increases and it is expected that higher profits can be expected by increasing the charge / discharge rate by lowering the degradation suppression intensity of the storage battery, the display control means 351 may prompt the user to lower the degradation suppression intensity by, for example, flashing the intensity image G2 for the corresponding time period in the information table I1. Also, for example, if the amount of electricity generated from renewable energy decreases and it is expected that higher profits can be expected by lowering the charge / discharge rate by increasing the degradation suppression intensity of the storage battery, the display control means 351 may prompt the user to increase the degradation suppression intensity by, for example, flashing the intensity image G2 for the corresponding time period in the information table I1. Furthermore, when flashing the intensity image G2, the flashing speed of the intensity image G2 and the color on the screen may be changed depending on whether the goal is to encourage a lower degradation suppression intensity or an increase in degradation suppression intensity.

[0055] Furthermore, for example, the display control means 351 may cause the display unit 33 to display a message prompting the user to increase the intensity. Figure 5 shows a first example of a message to be displayed on the display unit 33. As shown in Figure 5, the display control means 351 may, for example, display a message box on the display unit 33 that reads, "Please increase the degradation suppression intensity." Such a message box may be displayed superimposed on the screen shown in Figure 4, for example. Such a message box may be displayed when, as described above, a higher profit can be expected by reducing the charge / discharge amount by increasing the degradation suppression intensity of the storage battery. Furthermore, if lowering the degradation suppression intensity of the storage battery would lead to higher profits by increasing the charge and discharge rate, the display control means 351 may display a message box on the display unit 33 that reads, for example, "Please reduce the degradation suppression intensity."

[0056] Furthermore, for example, the display control means 351 may display a message on the display unit 33 prompting the user to confirm if the confirmed intensity information is changed by the modification means 353. The message prompting the user to confirm may also include revenue information indicating the revenue after the change made by the modification means 353. Figure 6 shows a second example of a message to be displayed on the display unit 33. As shown in Figure 6, the display control means 351 may, for example, display a message box on the display unit 33 that reads, "The degradation suppression intensity has been changed. The expected revenue based on the changed degradation suppression intensity is 30,000 yen." Such a message box may be displayed superimposed on the screen shown in Figure 4, for example. Such a message box may be displayed, for example, to prompt the user to confirm whether it is okay to reflect the change when the user changes the degradation suppression intensity using the modified image I4. In this embodiment, it is preferable that the degradation suppression strength of the storage battery be determined by the day before the operating day (for example, two days before). For example, the message shown in Figure 6 may be displayed if the degradation suppression strength of the storage battery is changed on the day of the operating day.

[0057] Confirmation step S3 is a step to confirm whether or not the user has given an instruction to terminate. As shown in Figure 3, the information processing step S1 and the display control step S2 are repeatedly executed if the user does not give an instruction to terminate (step S3: NO). The execution of the information processing step S1 and the display control step S2 may be performed at any time. If the user gives an instruction to terminate (step S3: YES), the flow shown in Figure 3 is terminated. The user may give an instruction to terminate, for example, by inputting an instruction to terminate via the input unit 32.

[0058] The display control method according to this embodiment is performed according to the above flow. While the information processing step S1 and the display control step S2 are repeatedly executed, the EMS 20 may communicate with the display control system 30 as needed to receive instructions from the user and control the power generation facility 10 as appropriate. Specifically, the EMS 20 may take the following actions based on the content corresponding to the intensity information set by the selection means 352 and the degradation suppression intensity set by the modification means 353. For example, if the selection means 352 is set to correspond to the C rate, the EMS 20 may decrease the C rate and reduce the charging and discharging speed of the battery as the degradation suppression intensity level increases by the modification means 353. Alternatively, the EMS 20 may increase the C rate and increase the charging and discharging speed of the battery as the degradation suppression intensity level decreases by the modification means 353. Furthermore, if the intensity information is set by the selection means 352 to correspond to the SOC level, the EMS 20 may decrease the SOC level and reduce the battery charge amount as the degradation suppression intensity level increases by the modification means 353. Alternatively, the EMS 20 may increase the SOC level and increase the battery charge amount as the degradation suppression intensity level decreases by the modification means 353. Furthermore, if the intensity information is set to correspond to temperature by the selection means 352, the EMS 20 may lower the temperature of the battery by cooling the battery with cooling equipment (not shown) or the like, as the degradation suppression intensity level increases by the modification means 353. Also, the EMS 20 may reduce the intensity of the battery cooling or stop the battery cooling altogether as the degradation suppression intensity level decreases by the modification means 353.

[0059] Figure 7 is a schematic diagram showing an example of the hardware configuration of the information processing device 90 applied to this embodiment. The information processing device 90 comprises a processor 91, main memory 92, communication interface 93, auxiliary storage device 94, input / output interface 95, and internal bus 96. The processor 91, main memory 92, communication interface 93, auxiliary storage device 94, and input / output interface 95 are connected to each other via the internal bus 96 so as to be able to communicate with each other. The information processing device 90 may be applied to, for example, a display control system 30. In this case, for example, the communication unit 31 may be configured using the communication interface 93. For example, the storage unit 34 may be configured using the auxiliary storage device 94. Furthermore, the control unit 35 may be configured using the processor 91 and the main memory 92.

[0060] As described above, according to the display control system 30 of this embodiment, the display control means 351 causes the display unit 33 to display intensity information indicating the intensity at which battery degradation is suppressed by the EMS 20, and energy amount information indicating the amount of energy that the EMS 20 discharges from the battery at the intensity indicated by the intensity information. This makes it possible to display the amount of battery discharge by the EMS 20 as energy amount information on the display unit 33. Furthermore, since the intensity information and power consumption information are displayed on the display unit 33, users can easily understand, for example, how much battery degradation is suppressed by the EMS 20, how much is discharged from the battery by the EMS 20, and how much the battery degrades. Therefore, it becomes easier for users to consider the amount of battery discharge in the EMS 20. Consequently, for example, users can flexibly change the amount of battery discharge in the EMS 20 depending on the time of day.

[0061] Furthermore, the display control means 351 displays the intensity information and the power consumption information in association with each other on the display unit 33. This ensures that the user can reliably grasp the intensity information and the corresponding power consumption information.

[0062] Furthermore, the display control means 351 displays the first time period information, which is the time period during which the battery is discharged, and the intensity information in association with each other on the display unit 33. This allows the user to reliably grasp the intensity information and the corresponding time period information. In addition, for example, by referring to the revenue information for the first time period, the user can easily understand how much the battery will deteriorate after the first time period has elapsed and how much profit can be obtained from the electricity discharged from the battery.

[0063] Furthermore, the display control means 351 displays on the display unit 33 the first time period information indicating the first time period for discharge and the intensity information for the first time period in association with each other, and also displays on the display unit 33 the second time period information indicating the second time period for discharge and the intensity information for the second time period in association with each other. This ensures that the user can reliably grasp the intensity information for the first time period and the corresponding first time period information, and also the intensity information for the second time period and the corresponding second time period information. Therefore, for example, by referring to revenue information for the first time period, users can easily understand how much the battery will degrade after the first time period has elapsed, and how much profit can be made from the electricity discharged from the battery. Similarly, by referring to revenue information for the second time period, users can easily understand how much the battery will degrade after the second time period has elapsed, and how much profit can be made from the electricity discharged from the battery.

[0064] Furthermore, the display control means 351 displays degradation degree information, which indicates the degree to which the storage battery has deteriorated based on the intensity information, on the display unit 33 along with the intensity information and the power consumption information. This allows the user to understand the degradation degree information along with the intensity information and the power consumption information.

[0065] Furthermore, the display control means 351 displays period information indicating the discharge period on the display unit 33 along with intensity information, power consumption information, and degradation degree information. The degradation degree information indicates the degree to which the battery degrades over the period indicated by the intensity information and the duration information. This allows the user to understand the period information along with the intensity information, power consumption information, and degradation degree information. Moreover, it allows the user to understand how much the battery will degrade after the period indicated by the period information has elapsed.

[0066] Furthermore, the degradation level information indicates the degree to which the battery degrades based on the intensity indicated by the strength information and the amount of power indicated by the power consumption information. This allows users to understand, through the degradation level information, how much the battery degrades based on the intensity indicated by the strength information (where degradation is suppressed) and the amount of discharge indicated by the power consumption information.

[0067] Furthermore, the degradation level information includes first degradation level information, which is the degradation level information for the first time period during which the battery is discharged, and second degradation level information, which is the degradation level information for the second time period during which the battery is discharged. This allows users to understand, based on the degradation level information, how much the battery degrades in the first time period and how much it degrades in the second time period.

[0068] Furthermore, the display control means 351 displays revenue information, which is the revenue generated by the EMS 20 and corresponds to the amount of electricity discharged, on the display unit 33 along with the intensity information and the amount of electricity. This allows the user to grasp the revenue information along with the intensity information and the amount of electricity.

[0069] Furthermore, the revenue information includes first revenue information, which is the revenue during the first time period when the battery is discharged, and second revenue information, which is the revenue during the second time period when the battery is discharged. This allows users to understand the revenue during the first time period and the revenue during the second time period through the revenue information.

[0070] Furthermore, the display control means 351 causes the display unit 33 to display C-rate information, which indicates the C-rate of the storage battery, along with intensity information and power consumption information. This allows the user to understand the C-rate information along with the intensity information and power consumption information.

[0071] Furthermore, the intensity information corresponds to one of the following: the C-rate of the battery, the SOC level of the battery, or the temperature of the battery. This allows the user to understand the intensity information corresponding to the C-rate, the SOC level, and the temperature of the battery.

[0072] Furthermore, the display control means 351 displays on the display unit 33 in a way that allows the user to determine whether the intensity information corresponds to the C rate, the SOC level, or the temperature. This allows the user to determine which of the above the intensity information corresponds to.

[0073] Furthermore, the display control system 30 includes a selection means 352 for selecting whether to associate the intensity information with the C-rate, the SOC level, or the temperature. This allows the user to arbitrarily decide which of the above to associate the intensity information with. Thus, for example, the user can appropriately grasp the necessary intensity information.

[0074] In this context, electricity derived from renewable energy sources is relatively valuable. Therefore, for example, if the amount of electricity generated from renewable energy sources increases, it may be possible to increase profits by increasing the amount of charge added to the battery, even if it means lowering the level at which battery degradation is suppressed. Therefore, the display control means 351 changes the display mode of the intensity information according to the amount of electricity generated from renewable energy. This allows the display control means 351 to change the display mode of the intensity information according to the amount of electricity generated from renewable energy. Thus, for example, it becomes easier for the user to appropriately set the intensity level that suppresses battery degradation and the amount of charge to the battery according to the amount of electricity generated from renewable energy.

[0075] Furthermore, the display control means 351 causes the display unit 33 to display a message prompting the user to increase the intensity of the suppression of battery degradation. This makes it easier for the user to realize that it is preferable to increase the intensity of the suppression of battery degradation.

[0076] Furthermore, the display control system 30 further includes a modification means 353 for changing intensity information. The power consumption information changes in response to the change in intensity information by the modification means 353. This allows the power consumption information to be appropriately changed in response to changes in intensity information by the modification means 353, for example. Thus, the user can obtain more accurate power consumption information.

[0077] Furthermore, the display control means 351 displays C-rate information, which indicates the C-rate of the storage battery, on the display unit 33 along with the intensity information and the power consumption information. The C-rate information changes in response to changes in the intensity information by the changing means 353. This allows the C-rate information to be appropriately changed in response to changes in the intensity information by the changing means 353, for example. Thus, the user can obtain more accurate C-rate information.

[0078] Furthermore, the display control means 351 displays maximum value information, which indicates the maximum charge / discharge amount of the storage battery, on the display unit 33 along with the intensity information and the power amount information. The maximum value information changes in response to changes in the intensity information by the modification means 353. This allows the maximum value information to be appropriately changed in response to changes in the intensity information by the modification means 353, for example. Thus, the user can obtain more accurate maximum value information.

[0079] Furthermore, the display control means 351 displays a message on the display unit 33 prompting the user to confirm if the confirmed intensity information is changed by the modification means 353. This makes it easier for the user to notice that the confirmed intensity information has been changed by the modification means 353.

[0080] Furthermore, the display control means 351 displays revenue information, which is the revenue generated by the EMS 20 corresponding to the amount of electricity discharged, on the display unit 33 along with the intensity information and the amount of electricity. The message prompting the user to confirm includes revenue information indicating the revenue after the intensity information has been changed by the modification means 353. This allows the user to understand the revenue corresponding to the changed intensity information, for example, when the confirmed intensity information is changed by the modification means 353. Thus, for example, it becomes easier for the user to decide whether or not to change the intensity that suppresses battery degradation.

[0081] Furthermore, the display control means 351 displays renewable energy information on the display unit 33, indicating whether or not the electricity discharged from the battery is derived from renewable energy, in association with the intensity information. This allows the user to understand whether or not the electricity discharged from the battery is derived from renewable energy.

[0082] Furthermore, the power consumption information indicates the amount of power used to discharge the battery and the amount of power used to charge the battery. This allows users to understand the amount of power used to discharge and charge the battery based on the power consumption information.

[0083] The technical scope of this disclosure is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of this disclosure. For example, in addition to the various types of information mentioned above, information table I1 may also display any other information as appropriate. Furthermore, the degradation degree information may include not only the first degradation degree information corresponding to the first time period and the second degradation degree information corresponding to the second time period, but also the third degradation degree information corresponding to the third time period and the fourth degradation degree information corresponding to the fourth time period. Furthermore, revenue information may include not only the first revenue information corresponding to the first time period and the second revenue information corresponding to the second time period, but also the third revenue information corresponding to the third time period and the fourth revenue information corresponding to the fourth time period.

[0084] Furthermore, it is possible to replace the components in the above embodiments with well-known components as appropriate, without departing from the spirit of this disclosure, and the above-described modifications may be combined as appropriate.

[0085] (Note) The display control system, display control method, and program according to the above embodiment can be understood, for example, as follows.

[0086] <1> A display control system according to one aspect of the present disclosure is characterized by comprising a display control means that causes a display unit to display intensity information indicating the intensity at which battery degradation is suppressed by the EMS, and energy amount information indicating the amount of energy that the EMS discharges from the battery at the intensity indicated by the intensity information.

[0087] According to the above-described display control system, the display control means displays intensity information indicating the strength at which battery degradation is suppressed by the EMS, and energy amount information indicating the amount of energy that the EMS discharges from the battery at the intensity indicated by the intensity information, on the display unit. This makes it possible to display the amount of battery discharge by the EMS as energy amount information on the display unit. Furthermore, by displaying both intensity and power consumption information on the display unit, users can easily understand, for example, how much battery degradation is suppressed by the EMS, how much is discharged from the battery by the EMS, and how much the battery degrades. Therefore, it becomes easier for users to consider the amount of battery discharge in the EMS. Consequently, for example, users can flexibly change the amount of battery discharge in the EMS depending on the time of day.

[0088] <2> the above <1> In the display control system relating to the above, the display control means may employ a configuration characterized by displaying the intensity information and the power amount information in association with each other on the display unit.

[0089] Furthermore, the display control means displays the intensity information and the power consumption information in association with each other on the display unit. This ensures that the user can reliably grasp the intensity information and the corresponding power consumption information.

[0090] <3> the above <1> or <2> In the display control system relating to the above, the display control means may employ a configuration characterized by displaying the first time period information indicating the first time period for discharge and the intensity information in association with each other on the display unit.

[0091] Furthermore, the display control means displays the first time period information, which is the time period during which the battery is discharged, and the intensity information in association with each other on the display unit. This allows the user to reliably grasp the intensity information and the corresponding time period information. In addition, for example, by referring to the revenue information for the first time period, the user can easily understand how much the battery will degrade after the first time period has elapsed, and how much profit can be obtained from the electricity discharged from the battery.

[0092] <4> the above <1> from <3> In a display control system according to any one of the embodiments, the display control means may be configured to display on the display unit a first time period information indicating a first time period for discharge and the intensity information during the first time period in association with each other, and to display on the display unit a second time period information indicating a second time period for discharge and the intensity information during the second time period in association with each other.
