[0010] Hereinafter, an embodiment of a communication system, a communication method, and a communication program according to the present disclosure will be described with reference to FIGS.

[0011] [1. Communication Systems] 1 processes at least carbon neutral information and private power generation information. More specifically, the communication system 1 processes carbon neutral information, private power generation information, wheeling charge information, wheeling charge requirement information, wheeling charge record information, levy information, private consumption information, power amount information, type information, and business operator identification information. First, each piece of information will be explained below.

[0012] Carbon neutral information means information indicating whether the electricity is of carbon neutral origin. For example, as shown in Table 1, carbon neutral information is expressed as "TRUE (electricity is of carbon neutral origin)" or "FALSE (electricity is not of carbon neutral origin)."

[0013] [Table 1]

[0014] Carbon-neutral sources here mean electricity generated using, for example, solar cells, wind power, hydroelectric power, geothermal power, wave power, tidal power, or biomass. The private power generation information means information indicating whether or not the power is self-generated. For example, the private power generation information is expressed as "TRUE (the power is self-generated)" or "FALSE (the power is not self-generated)" as shown in Table 1. The private power generation here means power generation using, for example, a solar cell or a generator.

[0015] Wheeling charge information refers to information that indicates the wheeling charge (transportation fee) for electricity. Wheeling charge here refers to the fee set by the general electricity transmission and distribution company as a usage fee for the electricity transmission and distribution network when transmitting electricity. A flat wheeling charge is charged for electricity purchased from outside. On the other hand, when that electricity is returned to the outside, the wheeling charge for that electricity is waived. The wheeling charge information includes wheeling charge requirement information and wheeling charge record information. The wheeling charge requirement information indicates whether wheeling charges are charged for electricity. For example, the wheeling charge requirement information is expressed as "TRUE (wheeling charges are charged for electricity)" or "FALSE (wheeling charges are not charged for electricity)." The wheeling charge record information refers to information indicating the wheeling charge record required for electricity. For example, the wheeling charge record information refers to information indicating the amount of wheeling charge required for electricity.

[0016] The surcharge information means information indicating the renewable energy surcharge for electricity and information on whether the surcharge is required. The renewable energy surcharge applies to the purchase and sale of electricity. For example, if you generate your own electricity and send it to your own factory, you will not be charged the renewable energy surcharge. For example, information indicating the renewable energy surcharge for electricity means information indicating the amount of the renewable energy surcharge for electricity. The levy requirement information indicates whether or not a renewable energy levy is applied to electricity.

[0017] The self-consumption information means information indicating whether or not the power is self-consumed. For example, the self-consumption information is expressed as "TRUE (power is self-consumed)" or "FALSE (power is not self-consumed)." The power amount information refers to information indicating the amount of power (kWh: kilowatt-hours). The type information indicates the type of carbon-neutral power generation method, such as solar cell, wind power, etc. The business operator identification information refers to information that identifies a business operator that transmits electric power.

[0018] Next, the communication system 1 will be described. 1, the communication system 1 is a computer. For example, the communication system 1 includes a CPU (Central Processing Unit) 10, a main memory device 15, an auxiliary memory device 20, an input / output interface (IO / I / F) 25, a recording / playback device 30, and a sensor 35. The CPU 10, the main memory device 15, the auxiliary memory device 20, the input / output interface 25, the recording / playback device 30, and the sensor 35 are connected to one another by a bus 40. The main storage device 15 is a RAM (Random Access Memory) or the like that serves as a work area for the CPU 10. The input / output interface 25 is connected to an input device 26 such as a keyboard and a mouse, and a display device 27 . A recording / playback device 30 records and plays back data on a recording medium 31 such as a USB (Universal Serial Bus) memory.

[0019] The auxiliary storage device 20 is an SSD (Solid State Drive) or the like that stores various data, programs, etc. The auxiliary storage device 20 stores various programs, such as a communication program 21 for causing the computer to function as the communication system 1, and an OS program. The various programs, including the communication program 21, are loaded into the auxiliary storage device 20 from a recording medium 31 via a recording / playback device 30. The communication program 21, etc. are stored in the recording medium 31. These programs may be loaded into the auxiliary storage device 20 from a disk-type recording medium such as a CD or DVD, or from an external device via a communication device (not shown).

[0020] The information shown in Table 1 is stored in the auxiliary storage device 20 and the recording / reproducing device 30 in a mutually associated manner. Table 1 may be displayed as an image on the display device 27. When this display is performed, the information shown in Table 1 is displayed on the display device 27 in a mutually associated manner.

[0021] The sensor 35 is connected to the storage battery 45. The storage battery 45 stores power. The sensor 35 measures the amount of power stored in the storage battery 45. Table 1 shows an example of the power stored in the storage battery 45. The storage battery 45 stores power No. 1 and power No. 2.

[0022] The CPU 10 executes various types of arithmetic processing. As shown in FIG. The transmission control means 11 is connected to a transmission unit 46 such as a router that actually transmits various information. Carbon neutral information, self-generation information, transmission fee information, transmission fee requirement information, actual transmission fee information, levy information, self-consumption information, power amount information, type information, and operator identification information may be transmitted in JSON (JavaScript Object Notation) format, for example, as shown in Figure 2.

[0023] The transmitter 46 is connected to a power transmission and distribution company system 50 and a guarantee company system 51, respectively. The power transmission and distribution company system 50 is a system used by a power transmission and distribution company (such as a general power transmission and distribution company). The communication system 1 performs forward power flow (power purchase) and reverse power flow (power sale) of power. The guarantee company system 51 is a system used by a guarantee company. The guarantee company guarantees that the electricity is of carbon-neutral origin.

[0024] The display control means 12 is connected to a display unit 47 such as a display that actually displays various information. The control means 13 is connected to an electricity transmission and distribution company system 50 and a storage battery 45 .

[0025] For example, the transmission control means 11 causes the transmission unit 46 to transmit the business operator identification information, the carbon neutral information, the private power generation information, and the power amount information in association with each other. The display control means 12 causes the display unit 47 to display the business operator identification information, the carbon neutral information, the private power generation information, and the power amount information in association with each other.

[0026] For example, a method for associating business operator identification information, carbon neutral information, private power generation information, and power amount information includes a method for assigning a common identifier to the array that stores the information.A method for associating business operator identification information, carbon neutral information, private power generation information, and power amount information and displaying them on display unit 47 includes a method for displaying the associated information in the same column, as shown in Table 1. In addition to business operator identification information, carbon neutral information, self-generation information, and power quantity information, Table 1 also displays transmission fee information, information on whether transmission fee is required, actual transmission fee information, levy information, self-consumption information, and type information.

[0027] The control means 13 causes the power to flow backward based on at least one of these pieces of information.

[0028] The transmission control means 11, display control means 12, and control means 13, which are functional components of the CPU 10, function when the CPU 10 executes a communication program 21, etc. stored in the auxiliary storage device 20. The communication program 21, etc. are programs for the communication system 1. The communication program 21 causes the communication system 1 to function as the transmission control means 11, display control means 12, and control means 13. The communication program 21 causes the computer to function as the communication system 1. For example, the transmission control means 11 causes the transmission unit 46 to transmit the business operator identification information, the carbon neutral information, the private power generation information, and the power amount information in association with each other. The display control means 12 causes the display unit 47 to display the business operator identification information, the carbon neutral information, the private power generation information, and the power amount information in association with each other.

[0029] [2. Communication Method] FIG. 3 is a flowchart showing the communication method S1 of this embodiment. The communication method S1 includes a transmission control step S10, a display control step S11, and a control step S12. In the transmission control step S10, the business operator identification information, the carbon neutral information, the private power generation information, and the power amount information are associated with each other and transmitted to the transmission unit 46. In the display control step S11, the business operator identification information, the carbon neutral information, the private power generation information, and the power amount information are displayed on the display unit 47 in association with each other. The control step S12 causes the power to flow backward based on the business operator identification information, carbon neutral information, private power generation information, power amount information, and the like.

[0030] 3. Modifications of the Communication System Embodiment In the communication system 1, the transmission control means 11, the display control means 12, and the control means 13 may be operated as follows. The transmission control means 11 causes the transmission unit 46 to transmit the carbon neutral information and the private power generation information in association with each other. The display control means 12 causes the display unit 47 to display the carbon neutral information and the private power generation information in association with each other.

[0031] The transmission control means 11 causes the transmission unit 46 to transmit the wheeling charge information, the carbon neutral information, and the private power generation information in association with each other. The display control means 12 causes the display unit 47 to display the carbon neutral information, private power generation information, and wheeling charge information in association with each other.

[0032] The transmission control means 11 causes the transmission unit 46 to transmit the wheeling charge requirement information, the carbon neutral information, and the private power generation information in association with each other. The display control means 12 causes the display unit 47 to display the carbon neutral information, the private power generation information, and the information on whether or not a wheeling charge is required in association with each other.

[0033] The display control means 12 causes the display unit 47 to display, in a distinguishable manner, which of the electric power is subject to a wheeling charge and which is not, as shown in Fig. 4. In Fig. 4, the electric power is displayed on the display unit 47 as a stacked bar graph. The height of the bar graph represents the amount of total power stored in the storage battery 45. The height of the unhatched area R1 represents the amount of power for which a wheeling charge is required. The height of the hatched area R2 represents the amount of power for which no wheeling charge is required. Areas R1 and R2 make it possible to distinguish between power for which a wheeling charge is required and power for which no wheeling charge is required.

[0034] The transmission control means 11 causes the transmission unit 46 to transmit the wheeling charge actual result information, the carbon neutral information, and the private power generation information in association with each other. The display control means 12 causes the display unit 47 to display the carbon neutral information, private power generation information, and wheeling charge record information in association with each other.

[0035] The transmission control means 11 causes the transmission unit 46 to transmit the levy information, the carbon neutral information, and the private power generation information in association with each other. The display control means 12 causes the display unit 47 to display the carbon neutral information, private power generation information, and levy information in association with each other.

[0036] The transmission control means 11 causes the transmitter 46 to transmit the self-consumption information, the carbon neutral information, and the self-power generation information in association with each other. The display control means 12 causes the display unit 47 to display the carbon neutral information, the private power generation information, and the private consumption information in association with each other.

[0037] The transmission control means 11 causes the transmission unit 46 to transmit the power amount information, the carbon neutral information, and the private power generation information in association with each other. The display control means 12 causes the display unit 47 to display the carbon neutral information, private power generation information, and power amount information in association with each other.

[0038] The transmission control means 11 controls the transmission unit 46 to transmit the self-generation information and the amount of power information to the power transmission and distribution company system 50, and to transmit the carbon neutral information, type information, and amount of power information to the guarantee company system 51.

[0039] The display control means 12 causes the display unit 47 to display the private power generation information, the power amount information, the carbon neutral information, and the type information transmitted by the transmission unit 46 in association with each other.

[0040] The control means 13 causes the power to flow backward (sell) based on the carbon neutral information, the private power generation information, and the power amount information. Generally, electricity that is shown to be of carbon-neutral origin by the carbon-neutral information and that is shown to be self-generated by the self-generation information can be sold at a higher price than other electricity because it can be used for advertising purposes by companies that consume that electricity. For this reason, the control means 13 causes that electricity to flow back to the power grid (not shown) within the amount indicated by the power amount information.

[0041] The control means 13 reverse-flows (sells) the power corresponding to the carbon-neutral information indicating that the power is of carbon-neutral origin (carbon-neutral information is TRUE) based on the private power generation information and the power amount information. In this case, for example, the control means 13 reverse-flows the power stored in the storage battery 45 to the power grid. The control means 13 reverses the flow of power corresponding to the carbon neutral information indicating that the power is not of carbon neutral origin (carbon neutral information is FALSE) based on the private power generation information and the power amount information. Generally, power that is not of carbon neutral origin may be reversed, for example, according to settings determined by one's own factory.

[0042] For example, if a company aims to have 100% of the electricity it uses come from carbon-neutral sources, it would reverse-flow all electricity that is not from carbon-neutral sources. For example, if your company aims to have 90% of the electricity it uses come from carbon-neutral sources, you would consume the 10% that fits within that figure, and reverse the flow of any excess.

[0043] 4. Effects of this embodiment As described above, in the communication system 1 and communication method S1 of this embodiment, the transmission control means 11 (in the transmission control step S10) can determine not only whether the power is carbon-neutral, but also whether the power is self-generated, for example, by an external device of the communication system 1. This makes it possible to advertise to the outside world that the power is self-generated and clean, carbon-neutral. Furthermore, the transmission control means 11 (in the transmission control step S10) determines that the electricity is not self-generated, and therefore, for example, if the electricity is purchased, no transmission charge is incurred when selling the electricity, and therefore it is determined that the transmission charge when selling the electricity will be cheaper.

[0044] Furthermore, the transmission control means 11 causes the transmitter 46 to transmit the business operator identification information, the carbon neutral information, the private power generation information, and the power amount information in association with each other. Therefore, the user of the communication system 1 can know whether the power is carbon neutral, whether the power is privately generated, the amount of the power, and the information identifying the business operator transmitting the power in association with each other. And because it is clear that the electricity is self-generated, it becomes easier to obtain subsidies that are available when, for example, 50% of the self-generated electricity is self-consumed. Furthermore, clean electricity can be purchased at a relatively higher price through transactions using the FIT (Feed-In Tariff) system, the FIP (Feed-In Premium) system, or through private transactions with businesses.

[0045] The transmission control means 11 may cause the transmission unit 46 to transmit the carbon-neutral information and the self-generated electricity information in association with each other. In this case, whether or not the electricity is carbon-neutral is associated with whether or not the electricity is self-generated, and the user can more easily understand this by visually checking what is displayed on the display unit 47. The display control means 12 may cause the carbon-neutral information and the private power generation information to be displayed in association with each other on the display unit 47. In this case, the user can understand whether the electricity is carbon-neutral, whether the electricity is privately generated, and the wheeling charges for that electricity, all in association with each other.

[0046] The transmission control means 11 may cause the transmission unit 46 to transmit the wheeling charge information, the carbon-neutral information, and the private power generation information in association with each other. In this case, it is possible to grasp whether the electricity is of carbon-neutral origin, whether the electricity is privately generated, and the wheeling charge for that electricity in association with each other. The display control means 12 may cause the carbon neutral information, the private power generation information, and the wheeling charge information to be displayed in association with each other on the display unit 47. In this case, whether or not the electricity is carbon neutral, whether or not the electricity is privately generated, and the wheeling charge for that electricity are associated with each other, and the user can more easily understand by visually checking what is displayed on the display unit 47.

[0047] The transmission control means 11 may cause the transmission unit 46 to transmit the wheeling charge requirement information in association with the carbon neutral information and the private power generation information. In this case, whether the electricity is carbon neutral or not, whether the electricity is privately generated or not, and whether wheeling charges are required for the electricity are associated with each other, making it easier for users to understand. The display control means 12 may cause the display unit 47 to display the carbon-neutral information, the private power generation information, and the information on whether or not a wheeling charge is required in association with each other. In this case, whether or not the electricity is carbon-neutral, whether or not the electricity is privately generated, and whether or not a wheeling charge is required for the electricity are associated with each other, and the user can more easily understand by visually checking what is displayed on the display unit 47.

[0048] The display control means 12 may cause the display unit 47 to distinguish between electricity that requires a wheeling charge and electricity that does not require a wheeling charge. In this case, the user can more easily understand the difference by visually checking the distinguishable display on the display unit 47 of electricity that requires a wheeling charge and electricity that does not require a wheeling charge.

[0049] The transmission control means 11 may cause the transmission unit 46 to transmit the wheeling charge record information in association with the carbon neutral information and the private power generation information. In this case, the user can understand whether the electricity is carbon neutral or not, whether the electricity is privately generated or not, and the wheeling charge record for that electricity in association with each other. The display control means 12 may cause the carbon-neutral information, the private power generation information, and the wheeling charge record information to be displayed in association with each other on the display unit 47. In this case, whether or not the electricity is carbon-neutral, whether or not the electricity is privately generated, and the wheeling charge record for that electricity are associated with each other, and the user can more easily understand by visually checking what is displayed on the display unit 47.

[0050] The transmission control means 11 may cause the transmission unit 46 to transmit the levy information, the carbon neutral information, and the private power generation information in association with each other. In this case, the user or the like can understand whether the electricity is of carbon neutral origin, whether the electricity is privately generated, and the renewable energy levy for that electricity, all in association with each other. The display control means 12 may cause the carbon neutral information, the private power generation information, and the levy information to be displayed in association with each other on the display unit 47. In this case, whether or not the electricity is of carbon neutral origin, whether or not the electricity is privately generated, and the renewable energy levy for that electricity are associated with each other, and the user can more easily understand by visually checking what is displayed on the display unit 47.

[0051] The transmission control means 11 may cause the transmitter 46 to transmit the self-consumption information, carbon-neutral information, and self-power generation information in association with each other. In this case, the users can understand whether the electricity is carbon-neutral, whether the electricity is self-generated, and whether the electricity is self-consumed, by associating these information. This allows the users to understand, for example, the renewable energy ratio of the facility that uses the electricity and whether a wheeling charge is required to transmit the electricity. The renewable energy electricity ratio of a facility here refers to the proportion of renewable energy (carbon-neutral energy) electricity out of the total electricity used at the facility.

[0052] The display control means 12 may cause the carbon-neutral information, the self-generation information, and the self-consumption information to be displayed in association with each other on the display unit 47. In this case, whether or not the electricity is of carbon-neutral origin, whether or not the electricity is self-generated, and whether or not the output is self-consumed are associated with each other, and the user can more easily understand by visually checking what is displayed on the display unit 47.

[0053] The transmission control means 11 may cause the transmission unit 46 to transmit the power amount information, the carbon neutral information, and the private power generation information in association with each other. In this case, whether the power is carbon neutral or not, whether the power is privately generated or not, and the amount of the power can be determined by associating them with each other, for example, by an external device of the communication system 1. The display control means 12 may cause the carbon-neutral information, the private power generation information, and the power amount information to be displayed in association with each other on the display unit 47. In this case, whether or not the electricity is of carbon-neutral origin, whether or not the electricity is privately generated, and the amount of the electricity are associated with each other, and the user can more easily understand by visually checking what is displayed on the display unit 47.

[0054] The transmission control means 11 may control the transmission unit 46 to transmit the private power generation information and the power amount information to the power transmission and distribution company system 50, and to transmit the carbon neutral information, type information, and power amount information to the guarantee company system 51. In this case, for example, the power transmission and distribution company using the power transmission and distribution company system 50 and the guarantee company using the guarantee company system 51 can each more reliably confirm the necessary information. The display control means 12 may cause the display unit 47 to display the in-house power generation information, the amount of power information, the carbon-neutral information, and the type information transmitted by the transmission unit 46 in association with each other. In this case, whether or not the power is in-house generated, the amount of that power, whether or not the power is carbon-neutral, and the type of power generation method are associated with each other, and the user can more easily understand the information displayed on the display unit 47 by visually checking it.

[0055] The control means 13 may cause the reverse flow of power based on the carbon-neutral information, the private power generation information, and the power amount information. In this case, the control means 13 may cause the reverse flow of power based on whether the power is of carbon-neutral origin, whether the power is privately generated, and the amount of the power. The control means 13 may reverse flow the power corresponding to the carbon-neutral information indicating that the power is of carbon-neutral origin based on the self-generation information and the power amount information. In this case, the control means 13 may reverse flow the power corresponding to the carbon-neutral information indicating that the power is of carbon-neutral origin based on whether the power is self-generated or not and the amount of the power.

[0056] The control means 13 may reverse flow power corresponding to carbon-neutral information indicating that the power is not of carbon-neutral origin based on the self-generation information and the power amount information. In this case, the control means 13 may reverse flow power corresponding to the carbon-neutral information indicating that the power is not of carbon-neutral origin based on whether the power is self-generated or not and the amount of the power.

[0057] The communication system 1 includes a sensor 35. Therefore, the sensor 35 makes it possible to more reliably grasp the amount of power. The power is discharged by the storage battery 45. Therefore, the storage battery 45 can reliably discharge the power.

[0058] Furthermore, the communication program 21 of this embodiment causes the computer to function as the communication system 1. Therefore, the communication program 21 allows the computer to function as the communication system 1.

[0059] One embodiment of the present disclosure has been described above in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and configuration changes, combinations, deletions, etc. are also included within the scope that does not deviate from the gist of the present disclosure. For example, in the above embodiment, the CPU 10 may not have at least one of the display control means 12 and the control means 13. In this case, the communication method S1 may not have at least one of the display control step S11 and the control step S12.

[0060] The communication system 1 does not necessarily have to include the sensor 35 . The transmitter 46 does not have to be connected to at least one of the electricity transmission and distribution company system 50 and the guarantee company system 51.

[0061] (Addendum) (1) Aspect 1 of the present disclosure is a communication system including a transmission control means that causes a transmitting unit to transmit carbon-neutral information indicating whether or not the electricity is of carbon-neutral origin and self-generation information indicating whether or not the electricity is self-generated, in association with each other.

[0062] In this disclosure, the transmission control means allows, for example, an external device of the communication system to determine not only whether the power is carbon-neutral but also whether the power is self-generated, thereby making it possible to advertise (appeal) to the outside world that the power is self-generated and clean, carbon-neutral. Furthermore, since the transmission control means determines that the power is not self-generated, for example, if the power is purchased, no wheeling charge is incurred when selling the power, and therefore it is determined that the wheeling charge when selling the power will be cheaper.

[0063] (2) A second aspect of the present disclosure may be a communication system according to (1), further comprising a display control means for displaying the carbon neutral information and the private power generation information in association with each other on a display unit. In this disclosure, whether or not the electricity is carbon-neutral is associated with whether or not the electricity is self-generated, and the user can more easily understand this by visually checking what is displayed on the display unit.

[0064] (3) Aspect 3 of the present disclosure may be a communication system described in (1) or 2, in which the transmission control means causes the transmitting unit to transmit, in association with transmission fee information indicating the transmission fee for the electricity, the carbon neutral information, and the self-generation information. This disclosure makes it possible to correlate and grasp whether electricity is carbon-neutral, whether that electricity is self-generated, and the wheeling charges for that electricity.

[0065] (4) Aspect 4 of the present disclosure may be a communication system as described in (3), further comprising a display control means for displaying the carbon neutral information, the self-generation information, and the wheeling charge information in association with each other on a display unit. In this disclosure, whether or not the electricity is carbon-neutral, whether or not the electricity is self-generated, and the transmission charges for that electricity are correlated, and the user can more easily understand this by visually checking what is displayed on the display unit.

[0066] (5) Aspect 5 of the present disclosure may be a communication system described in any one of (1) to (4), in which the transmission control means causes the transmitting unit to transmit, in association with transmission charge requirement information indicating whether or not transmission charges are required for the electricity, the carbon neutral information, and the self-generation information. This disclosure makes it easier to understand whether electricity is carbon-neutral, whether that electricity is self-generated, and whether or not a wheeling charge is incurred for that electricity by correlating these two.

[0067] (6) Aspect 6 of the present disclosure may be a communication system described in (5), further comprising a display control means for displaying the carbon neutral information, the self-generation information, and the information on whether or not a wheeling charge is required in association with each other on a display unit.
