[Figure 7] This figure shows a message screen displayed on the display of a measuring device according to an embodiment of the present invention. [Modes for carrying out the invention]

[0009] Hereinafter, a local currency dispensing device, a local currency dispensing method, and a program according to embodiments of the present invention will be described in detail with reference to the drawings. In each drawing, the same or equivalent parts are denoted by the same reference numerals.

[0010] The local currency granting system according to this embodiment is a system that grants local currency to each user in accordance with the amount of renewable energy electricity consumed by the user (amount of electricity consumed by the user). A user is an individual or organization that has installed renewable energy power generation equipment in a building that they own or manage. Renewable energy electricity is electricity derived from renewable energy, such as electricity generated by renewable energy power generation equipment such as solar power generation equipment, wind power generation equipment, and geothermal power generation equipment.

[0011] Self-consumption of renewable energy electricity means that a user generates renewable energy electricity using renewable energy equipment they have installed, and then consumes this renewable energy electricity themselves. The timing of generating renewable energy electricity and the timing of consumption do not need to coincide; the generated renewable energy electricity can be temporarily stored in a battery and consumed at a desired time.

[0012] Self-consumption of renewable energy leads to a reduction in fossil fuel consumption, thus contributing to the reduction of CO2 emissions. When the reduced CO2 emissions are certified by a certification body, they become tradable as emission rights called carbon credits. The purchaser of carbon credits can offset the CO2 emissions they have generated with the purchased carbon credits. Carbon credits are expressed in units of the weight of greenhouse gases and are certified by the J-Credit system operated by the state in Japan.

[0013] Regional currency is a currency that can circulate within a region and is put into practical use in various forms such as banknotes, gift certificates, points, and electronic money. By using regional currency within the region, users can circulate the value of the region within the region and prevent the outflow of that value outside the region. In the regional currency granting system according to the embodiment, funds can be called in from outside the region in exchange for the environmental value guaranteed by carbon credits, and moreover, the added value of regional currency can be improved by associating it with environmental protection. Therefore, the number of users and the circulation volume of regional currency can be increased more than before.

[0014] Hereinafter, referring to FIG. 1, the configuration of the regional currency granting system according to the embodiment will be described. In the embodiment, the case of using a solar power generation facility as a renewable energy power generation facility will be described as an example.

[0015] The regional currency granting system 1 includes a measurement device 100 and a regional currency granting server 200. The measurement device 100 and the regional currency granting server 200 are communicably connected to each other via a communication line such as the Internet, for example.

[0016] The measurement device 100 periodically measures the power generation amount and the power selling amount by the solar power generation facility, calculates the power generation amount and the power selling amount during the measurement target period based on the measured power generation amount and power selling amount, and transmits them to the regional currency awarding server 200. The measurement device 100 includes, for example, a smart meter and a user interface connected to the smart meter for input / output with the user. The measurement device 100 is installed in a building where the solar power generation facility is installed and is electrically connected to the solar power generation facility.

[0017] The regional currency awarding server 200 is an example of a regional currency awarding device that awards regional currency to each user based on the power generation amount and the power selling amount acquired from each measurement device 100. The regional currency awarding server 200 is, for example, a general-purpose computer. The regional currency awarding server 200 is managed by an administrator who implements all or part of the application, acquisition, and sale of carbon credits, and the acquisition and distribution of regional currency. The administrator is, for example, a person belonging to a local government, a company, an NPO (Nonprofit Organization), or other corporation or organization, or a person who has received a commission from them.

[0018] The outline of the procedure until awarding regional currency using the regional currency awarding system according to the embodiment will be described. First, when the regional currency awarding server 200 acquires the power generation amount and the power selling amount during the measurement target period by the solar power generation facility from the measurement device 100, it calculates the total value obtained by summing up the self-consumption power amounts of all users during the measurement target period. Next, the administrator applies to the certification authority for the certification of carbon credits based on the total value of the self-consumption power amounts. When the carbon credits are certified by the certification authority, the administrator sells the carbon credits to the purchaser through market transactions. Next, the administrator requests the regional currency issuer to issue regional currency using the proceeds (funds) obtained from the sale of carbon credits, and obtains regional currency from the regional currency issuer. When the administrator inputs the amount of the regional currency obtained into the regional currency awarding server 200, the regional currency awarding server 200 allocates and awards the amount of the regional currency obtained according to the self-consumption power amount of each user. The above is the outline of the procedure until awarding regional currency.

[0019] Next, with reference to Figure 2, the hardware configuration of the measuring device 100 according to the embodiment will be described. The measuring device 100 includes an operation unit 110, a display unit 120, a measurement unit 130, a communication unit 140, a storage unit 150, and a control unit 160. Each part of the measuring device 100 is interconnected via an internal bus (not shown).

[0020] The operation unit 110 receives instructions from the user managing the measuring device 100 and supplies operation signals corresponding to the received operations to the control unit 160. The display unit 120 displays various images to the administrator based on image data supplied from the control unit 160. The display unit 120 displays, for example, a message regarding the amount of local currency granted to each user.

[0021] The operation unit 110 and the display unit 120 are integrated, for example, by a touch panel. The touch panel displays an operation screen that accepts user input and supplies an operation signal to the control unit 160 corresponding to the position where the user makes a contact operation on the operation screen.

[0022] The measurement unit 130 periodically measures the amount of electricity generated and sold, and stores the data in the storage unit 150. The length of the measurement period is set in advance by the administrator, for example, every week, every month, or every quarter.

[0023] The communication unit 140 is a communication interface for the measuring device 100 to communicate with external devices. The communication unit 140 communicates with external devices via a communication network such as the Internet. For example, the communication unit 140 transmits the amount of power generated and the amount of electricity sold during the measurement period, calculated by the measuring unit 130, to the local currency granting server 200, and also receives a message from the local currency granting server 200 regarding the amount of local currency that the user will receive.

[0024] The storage unit 150 includes, for example, RAM (Random Access Memory), ROM (Read Only Memory), and flash memory. The storage unit 150 stores programs executed by the control unit 160 and various data, such as periodically measured values ​​of power generation and electricity sales, the timing for calculating power generation and electricity sales for each measurement period, and device IDs (Identification) individually assigned to the measuring device 100. The device ID is an example of identification information for identifying the measuring device 100. The storage unit 150 also temporarily stores various information and functions as a work memory for the control unit 160 to execute processing.

[0025] The control unit 160 is equipped with a processor and controls each part of the measuring device 100. The processor is, for example, a CPU (Central Processing Unit). The control unit 160 executes the local currency granting process shown in Figure 5 by executing a program stored in the storage unit 150. Specifically, the control unit 160 causes the measuring unit 130 to periodically measure the amount of electricity generated and the amount of electricity sold, and stores this data in the storage unit 150. At a predetermined timing, the control unit 160 reads the measured values ​​of the amount of electricity generated and the amount of electricity sold within the measurement period from the storage unit 150 and calculates the amount of electricity generated and the amount of electricity sold for each measurement period by summing them up. After that, it controls the communication unit 140 to transmit the amount of electricity generated and the amount of electricity sold during the measurement period, along with the device ID, to the local currency granting server 200. The above describes the hardware configuration of the measuring device 100.

[0026] Next, with reference to Figure 3, the hardware configuration of the local currency distribution server 200 according to the embodiment will be described. The local currency distribution server 200 includes an operation unit 210, a display unit 220, a communication unit 230, a storage unit 240, and a control unit 250. Each part of the local currency distribution server 200 is interconnected via an internal bus (not shown).

[0027] The operation unit 210 receives instructions from the administrator managing the local currency distribution server 200 and supplies operation signals corresponding to the received operations to the control unit 250. The operation unit 210 includes, for example, a mouse and a keyboard. The display unit 220 displays various images to the administrator based on image data supplied from the control unit 250.

[0028] The communication unit 230 is a communication interface for the local currency distribution server 200 to communicate with external devices. The communication unit 230 communicates with external devices via a communication network such as the Internet. For example, the communication unit 230 receives the amount of power generated and the amount of electricity sold transmitted from the measuring device 100 and sends a message to the measuring device 100 regarding the amount of local currency distributed to each user.

[0029] The memory unit 240 includes, for example, RAM, ROM, flash memory, and a hard disk. The memory unit 240 stores programs and various data executed by the control unit 250. The memory unit 240 also temporarily stores various information and functions as work memory for the control unit 250 to execute processing. Furthermore, the memory unit 240 includes an energy storage unit 241 and a local currency storage unit 242.

[0030] As shown in Figure 4(a), the power storage unit 241 stores the amount of power generated, the amount of power sold, and the amount of self-consumption for each measurement period, associating them with the device ID of each measuring device 100.

[0031] As shown in Figure 4(b), the local currency storage unit 242 stores the amount of local currency granted to the user according to the amount of self-consumption of electricity for each measurement period, in association with the device ID of each measuring device 100.

[0032] Returning to Figure 3, the control unit 250 includes a processor and controls each part of the local currency distribution server 200. The processor is, for example, a CPU. The control unit 250 executes the local currency distribution process in Figure 5 and the calculation process in Figure 6 by executing a program stored in the storage unit 240. Functionally, the control unit 250 includes an acquisition unit 251, a calculation unit 252, a distribution unit 253, and an output unit 254.

[0033] The acquisition unit 251 acquires the amount of electricity generated and the amount of electricity sold by the solar power generation equipment during the measurement period, transmitted from each measuring device 100, as well as the device ID of each measuring device 100, and stores them in the power amount storage unit 241 shown in Figure 4(a). The acquisition unit 251 also acquires the amount of local currency entered by the administrator by operating the operation unit 210. Note that data acquisition by the acquisition unit 251 includes not only acquiring data from external devices but also reading data stored in the storage unit 240.

[0034] The calculation unit 252 calculates the amount of self-consumption power for each user during the measurement period and stores it in the power storage unit 241 shown in Figure 4(a). The amount of self-consumption power is calculated by subtracting the amount of electricity sold during the measurement period from the amount of electricity generated by the solar power generation equipment during the same period. The calculation unit 252 also calculates the total amount of self-consumption power for all users during the measurement period by summing up the self-consumption power amounts calculated for each user.

[0035] The distribution unit 253 distributes the local currency obtained based on the total amount of self-consumption of electricity during the measurement period calculated by the calculation unit 252, according to the amount of self-consumption of electricity for each user during the measurement period, and stores it in the local currency storage unit 242 in Figure 4(b). The distribution of local currency involves allocating the amount of local currency to each user based on the ratio of the total amount of local currency to be distributed to the amount of self-consumption of electricity for each user. Specifically, the total amount of local currency obtained is allocated to each user according to the following calculation formula. Amount of local currency to be awarded to each user = Total amount of local currency received × (Each user's self-consumption of electricity / Total self-consumption of electricity)

[0036] The output unit 254 outputs to the outside the total amount of self-consumption power consumed during the measurement period, which is calculated by the calculation unit 252. For example, when the output unit 254 receives an operation from the operation unit 210, it displays the total amount of self-consumption power consumed during the measurement period on the display unit 220 so that the administrator can understand it.

[0037] Furthermore, the output unit 254 outputs to the outside the amount of local currency allocated to each user by the distribution unit 253. For example, the output unit 254 sends an instruction to the local currency server requesting that the amount of local currency allocated to each user by the distribution unit 253 be reflected in each user's local currency balance. Each user's local currency balance is stored in the local currency server's memory unit, and upon receiving the request, the local currency server updates each user's local currency balance by adding the amount of local currency allocated to each user to the balance of each user's local currency stored in the memory unit. The output unit 254 also sends a message regarding the amount of local currency allocated to each user to each measuring device 100. The above describes the hardware configuration of the local currency distribution server 200.

[0038] (Local currency distribution process) The following describes the flow of the local currency distribution process performed collaboratively by the measuring device 100 and the local currency distribution server 200, with reference to the flowchart in Figure 5. The local currency distribution process is the process of distributing local currency to each user according to the amount of renewable energy electricity consumed by the user. The local currency distribution process starts when the target measurement period has elapsed and a timing predetermined by the administrator has been reached. The measuring unit 130 of each measuring device 100 periodically measures the amount of electricity generated and sold by the solar power generation equipment and sequentially stores the measurement results in the storage unit 150.

[0039] First, the control unit 160 of each measuring device 100 calculates the amount of electricity generated and the amount of electricity sold during the measurement period at a predetermined timing (step S11). In this process, the data on the amount of electricity generated and the amount of electricity sold during the measurement period stored in the storage unit 150 of each measuring device 100 is read and summed up. The predetermined timing can be, for example, the first day of the following month if the amount of electricity generated and sold each month is to be calculated. In this case, each measuring device 100 only needs to collect and store the data for that month by the end of the month.

[0040] Next, the control unit 160 of each measuring device 100 controls the communication unit 140 to transmit the amount of power generated and the amount of electricity sold during the measurement period, calculated in step S11, along with the device ID stored in the storage unit 150, to the local currency granting server 200 (step S12).

[0041] The acquisition unit 251 of the local currency granting server 200 receives the amount of electricity generated and sold during the measurement period, along with the corresponding device IDs, from all measuring devices 100, and stores them in the power amount storage unit 241 shown in Figure 4(a) (step S21). Next, the calculation unit 252 performs calculation processing to calculate the amount of self-consumption of all users during the measurement period based on the amount of electricity generated and sold from all measuring devices 100 during the measurement period received in the processing of step S21 (step S22). The flow of calculation processing performed by the local currency granting server 200 will be explained below with reference to Figure 6.

[0042] (Calculation process) First, the calculation unit 252 calculates the amount of self-consumption of electricity for each user during the measurement period based on the amount of electricity generated and sold during the measurement period for each user, and stores it in the power storage unit 241 shown in Figure 4(a) in association with the device ID and the measurement period (step S31).

[0043] Next, the calculation unit 252 calculates the total amount of self-consumption power consumed during the measurement period for all users calculated in step S31 (step S32), and returns the process. Specifically, it simply needs to sum up all the self-consumption power consumed in step S31. The above is the flow of the calculation process.

[0044] When the operation unit 210 receives an operation from the administrator, the output unit 254 displays the total value of the self-consumption power consumption calculated by the calculation process in Figure 6 on the display unit 220 (step S23).

[0045] The administrator refers to the amount of self-consumption of electricity during the measurement period displayed on the display unit 220 and applies to the certification body for carbon credit certification based on this. Under the J-Credit system, carbon credits can be obtained through the following three steps. Note that the application for carbon credits may be made on behalf of the administrator by another business, such as a credit application supporter or a power company. 1. The manager will create a plan outlining how greenhouse gas emission reductions will be achieved and register it as a project with a certification body. 2. The administrator implements the project and monitors the reduction in greenhouse gas emissions resulting from that project. 3. The administrator submits the monitoring results to the certification body. Once the monitoring results are certified by the certification body, the administrator is awarded carbon credits.

[0046] When the administrator obtains carbon credits, they sell the carbon credits to buyers on the trading market and receive funds as a result. These funds may be in the form of legal tender, electronic money, or cryptocurrency. The administrator uses these funds to request a local currency business to issue local currency. When the administrator obtains local currency from the local currency business, they operate the operation unit 210 of the local currency distribution server 200 to input the amount of local currency obtained based on the amount of self-consumption of electricity during the measurement period.

[0047] When the acquisition unit 251 of the local currency distribution server 200 acquires the amount of local currency corresponding to the total amount of self-consumption power consumed during the measurement period (step S24), the distribution unit 253 distributes the local currency to each user according to the amount of self-consumption power consumed during the measurement period stored in the power consumption storage unit 241 in Figure 4(a) (step S25). Specifically, it calculates the amount of local currency to be distributed to each user according to the proportion of each user's self-consumption power consumed during the measurement period, and stores the amount of local currency to be distributed to each user in the local currency storage unit 242 in Figure 4(b), associating it with the target period and device ID.

[0048] Next, the output unit 254 sends an instruction to the local currency server requesting that the amount of local currency allocated calculated in step S25 be reflected in each user's local currency balance, and also sends a message regarding the amount of local currency allocated to the measuring device 100 (step S26). Each user's local currency balance is stored in the local currency server's memory unit, and the local currency server updates each user's local currency balance by adding the amount of local currency allocated to each user to the balance of each user's local currency stored in the memory unit.

[0049] When the control unit 160 of each measuring device 100 receives a message regarding the amount of local currency to be awarded, transmitted in the process of step S26 (step S13), it displays the received message on the display unit 120 in the process of step S13 (step S14), and then terminates the process. The display unit 120 of each measuring device 100 may, for example, display the screen shown in Figure 7. The above is the flow of the local currency distribution process.

[0050] As described above, the local currency distribution server 200 according to the embodiment includes an acquisition unit 251 that acquires the amount of power generated and the amount of electricity sold by the solar power generation equipment installed by each user during the measurement period, a calculation unit 252 that calculates the total amount of self-consumption of all users during the measurement period based on the acquired amount of power generated and the amount of electricity sold for each user, and a distribution unit 253 that distributes the local currency obtained based on the calculated total amount of self-consumption to each user according to the amount of self-consumption of each user during the measurement period.

[0051] Therefore, users do not need to read the amount of electricity generated and sold and report it to the administrator. house There is no need to pre-monitor the relationship between electricity consumption and CO2 emissions. Furthermore, by regularly awarding users local currency based on their self-consumption, users are motivated to reduce their CO2 emissions. This promotes the introduction of renewable energy power generation facilities by users and stimulates the local economic cycle.

[0052] The present invention is not limited to the embodiments described above, and the following modifications are also possible.

[0053] (modified version) In the above embodiment, each measuring device 100 measured and transmitted the amount of power generated and the amount of electricity sold, but the present invention is not limited to this. For example, each measuring device 100 measured and transmitted the amount of power generated and the amount of electricity sold. house The amount of power consumed may be measured and transmitted. In this case, the local currency distribution server 200 will measure each user's own house The calculation of power consumption is omitted, and all users house In calculating power consumption, the data obtained from each user house All you need to do is add up the power consumption.

[0054] In the above embodiment, each measuring device 100 calculated the amount of power generated and the amount of electricity sold for each measurement period at a predetermined timing, but the present invention is not limited to this. For example, the local currency granting server 200 may send polling signals to each measuring device 100 to calculate the amount of power generated and the amount of electricity sold for each measurement period.

[0055] In the above embodiment, the local currency distribution server 200 obtained the amount of electricity generated and sold during the measurement period from each measuring device 100 and calculated the total amount of self-consumption of electricity for all users during the measurement period based on these, but the present invention is not limited to this. The above processing may be performed by a server different from the local currency distribution server 200 (a power server) and the data may be transmitted to the local currency distribution server 200.

[0056] In the above embodiment, the administrator applied to a certification body for carbon credit certification based on the total amount of self-consumption of all users during the measurement period, but the present invention is not limited to this. For example, the local currency granting server 200 applies to a certification body for carbon credit certification based on the total amount of self-consumption of all users during the measurement period. house Alternatively, data showing the relationship between the total amount of electricity consumed and carbon credits may be stored in the storage unit 240 in advance, and carbon credits may be calculated based on the total amount of electricity consumed by all users during the measurement period by referring to this data. Alternatively, the local currency granting server 200 may transmit data on the total amount of electricity consumed by all users to the certification authority server, and the certification authority server may transmit data showing the amount of carbon credits to the local currency granting server 200.

[0057] In the above embodiment, the administrator sold carbon credits to a buyer and obtained funds from the result; however, the present invention is not limited to this. For example, the local currency granting server 200 may transmit carbon credit data to the carbon credit trading server, and the carbon credit trading server may transfer funds to the registered administrator's bank account and transmit data indicating the funds to the local currency granting server 200.

[0058] In the above embodiment, the administrator requested a local currency operator to issue local currency in exchange for funds obtained from the sale of carbon credits, but the present invention is not limited to this. For example, the administrator may use carbon credits to offset the CO2 emissions generated by its own business and request the issuance of local currency using its own funds. Alternatively, the administrator may be commissioned by a local currency operator or may implement a local currency business itself and issue local currency.

[0059] In the above embodiment, the funds obtained from selling carbon credits were used to issue local currency, but the present invention is not limited to this. For example, a portion of the funds obtained from selling carbon credits may be set aside as operating expenses or revenue, and the surplus funds may be used to request the issuance of local currency.

[0060] In the above embodiment, a message regarding the amount of local currency to be awarded was sent to the measuring device 100, but the present invention is not limited thereto. For example, the device ID of the measuring device 100 and the email address of the user who possesses the measuring device 100 may be associated with each other and stored in the storage unit 240 in advance, and a message regarding the amount of local currency to be awarded may be sent to the user's smartphone using the email address. In this case, the operation unit 110 and the display unit 120 of the measuring device 100 may be omitted.

[0061] In the above embodiment, the energy storage unit 241 and the local currency storage unit 242 were separate data tables, but the present invention is not limited thereto. For example, a data table may be created that groups each item of the energy storage unit 241 and the local currency storage unit 242 by device ID.

[0062] In the above embodiment, the measuring device 100 and the local currency distribution server 200 were connected to each other via a communication line such as the Internet, but the present invention is not limited to this. For example, the measuring device 100 and the local currency distribution server 200 may be connected to each other via a dedicated communication line.

[0063] In the above embodiment, various data were stored in the storage units 150 and 240 of the measuring device 100 and the local currency granting server 200, but the present invention is not limited thereto. For example, all or part of the various data may be stored in an external control device or computer via a communication network.

[0064] In the above embodiment, the measuring device 100 and the local currency distribution server 200 operated based on programs stored in the storage units 150 and 240, respectively, but the present invention is not limited thereto. For example, a functional configuration realized by a program may be realized by hardware.

[0065] In the above embodiment, the local currency distribution server 200 was, for example, a general-purpose computer, but the present invention is not limited thereto. For example, the local currency distribution server 200 may be implemented as a computer located on the cloud.
