Description

  The present invention relates to an environmental value-added securitization system, and more particularly to a system in which a green power generator and an environmental value-added purchaser can smoothly trade by securitization.

  Energy supply systems using fossil fuels such as coal, oil, and natural gas are not only depleted of fossil fuels, but also have an impact on global warming due to increased carbon dioxide emissions This is also a big problem. As the problems resulting from consumption of fossil fuels become more serious, expectations for new energy that does not depend on fossil fuels are increasing year by year.

  For example, nuclear power generation has an advantage in that it does not consume fossil fuels. However, in recent years, power generation using renewable energy such as geothermal power generation, tidal power generation, wave power generation, wind power generation, hydropower generation, solar power generation, etc. For example, there is no worry about exhaustion of resources and no carbon dioxide emissions from combustion. Furthermore, there is great expectation because it does not involve energy imports and is considered to be highly safe and environmentally friendly.

  Furthermore, among power generation using renewable energy, hydropower, geothermal power, tidal power generation, wind power generation, etc. generally require large-scale facilities. Compared with these, solar power generation is a unit of capital investment. Is small, making it easy to enter even small businesses. In addition, in order to encourage the use of such small-scale solar power generation, Japan has also adopted a policy of purchasing generated power at a fixed price. Furthermore, the power generated by small-scale power generation companies with unstable supply is managed in detail in real time using smart meters, making it easier to buy and sell power.

  Electricity generated by power generation that does not involve combustion of fossil fuels and does not emit carbon dioxide is called green power, and is a burden on the environment compared to power generated by the generation of carbon dioxide by combustion of fossil fuels. This value is called “environmental added value”, “environmental value”, or “green power added value” as the cost of the product is low.

  For this reason, for example, as shown in Patent Document 1, a system is proposed in which the environmental value added of a green power generator is separated from the supply of power and the environmental value added is bought and sold through a communication system. It was.

  FIG. 7 is a schematic diagram showing conventional securitized environmental value added and power transactions. The upper side of the figure shows the flow of information on the environmental value added through the communication line, and the lower side shows the flow of actual power transactions.

  As a mechanism for promoting the introduction of conventional renewable energy into the market, the green power generator 102 performs solar power generation and sells the green power GE to the power transmission and distribution company 107. On the other hand, the power transmission / distribution company 107 pays a consideration (purchased power charge) for the green power GE purchased from the green power generator 102.

  The green power generator 102 transfers the environmental value-added EV generated by the green power generation to the green power certificate issuer 105, and through the green power certificate issuer 105, the incorporated foundation Japan Apply for power generation facilities and power consumption at the Institute of Energy Economics and Clean Energy Certification Center 106. The green energy authentication center 106 authenticates the facilities of the green power generator 102 and authenticates the amount of power. In response to this authentication, when the green power certificate issuer 105 has applied for purchase of the green power certificate TGC from the certificate purchaser 103 who is a power consumer, the environment held by the green power certificate issuer 105 Based on the value-added EV, the environmental value-added EV is transferred to the certificate purchaser 103, and a green power certificate TGC is issued as proof. The certificate purchaser 103 pays a value corresponding to the transferred environmental value added EV.

  The certificate purchaser 103 supplies the green power GE within the range having the green power certificate TGC even when the non-green power EP generated by fossil fuel other than renewable energy is supplied from the transmission / distribution company 108. It is regarded as having been received.

  In other words, the securities purchaser 103 who is a large power consumer purchases the “Green Power Certificate TGC” securitized separately from the power, and how the power generation method of the non-green power EP supplied by himself / herself is determined. Regardless, it is recognized by society that it has contributed to the environment as being equivalent to using green power GE.

JP 2003-108655 A

  Traditionally, Japan has adopted a feed-in tariff system in terms of policy, and electricity has been purchased at a flat rate. For this reason, environmental added value was generated at a fixed rate according to the amount of power generation, so that the transaction was relatively simple, and it was easy to securitize small-scale environmental added value together in a fixed unit.

  However, the price of electricity fluctuates when the green electricity market opens and the feed-in tariff system ends. Then, the value of environmental added value will fluctuate accordingly. Furthermore, environmental added value and electric power are separated and traded. As a result, a large number of environmental value-added items whose prices are not decided on a small scale per unit time are generated by small-scale power generation companies, and these are put on the market. If these are to be traded in real time, the processing is enormous and complicated, and it is expected that the current method cannot be used.

  Therefore, the present invention aims to provide an environmental value securitization system that enables even a small green power generator to smoothly and easily conduct environmental value transactions that are securitized with a consumer on a network. .

  In order to solve the above problems, in the environmental value-added securitization system of the present invention, a power generator terminal of a power generator that generates a plurality of green powers, a consumer terminal of a plurality of power consumers, an environmental securities transaction A computer network that constitutes a blockchain having a transaction server at a place, the transaction server receives information on the amount of power generated by the green power generator, and responds to the environmental added value generated according to the amount of power generated Giving an environmental certificate with environmental value-added points to a power generator terminal, the consumer terminal holding virtual currency points purchased by a power consumer, and the transaction server from the power generator terminal to the environmental security A sell order which is a request to exchange the virtual currency points for the virtual currency points, and a buy order which is a request to exchange the virtual currency points for the environmental securities from the consumer terminal Is received, the exchange rate is calculated based on the quantity of the sell order and the quantity of the buy order in a specific aggregation time zone, and the exchange rate calculated on the basis of the aggregation time zone is a constant value thereafter. The environmental securities are exchanged for virtual currency points for newly received selling orders during the trading time period, virtual currency points are given to the power generator terminals, and the virtual currency points are exchanged for environmental securities for buying orders. The gist is that environmental securities are given to the consumer terminal, and the transaction is organized into blocks by the transaction server and registered in a block chain list.

  According to the present invention, environmental securities certifying possessing environmental added value are virtually issued and granted in the blockchain, so that the participants of the blockchain can easily view the records and illegal And tampering are prevented.

Moreover, since the invisible environmental added value is securitized as environmental securities on the network, it can be visualized and traded easily and instantaneously on the network.
And since the determination of the exchange rate and the exchange of environmental securities and virtual currency points at the exchange rate are performed continuously, the green power generators and the power consumers are able to appropriately reflect the supply and demand situation of the environmental securities. You can buy and sell environmental securities on the condition that the exchange rate is fixed.

  In the present invention, preferably, the amount of power generated by the power generator is detected and accumulated by a smart meter arranged in each power generator, and smart meter data is stored in a trading server of the environmental stock exchange at regular intervals. By being transmitted, the environmental security is granted to the power generator corresponding to the transaction server at regular intervals.

Further, in the present invention, preferably, the next counting time zone is continuous after the end of the counting time zone, and the next buying and selling time zone is continued after the end of the trading time zone.
Desirably, the transaction server presents the environmental added value generated in the power generator and the required amount of the environmental added value generated in the consumer to each power generator and each consumer so that they can be compared at regular intervals. To do.

  According to the present invention, even a small-scale green power generator can smoothly and easily transact the environmental value securitized with a large consumer in a small unit on the network.

(First embodiment)
Hereinafter, an embodiment of an environmental value-added securitization system embodying the present invention will be described with reference to FIGS. FIG. 1 is a schematic diagram showing a transaction of power itself, and FIG. 2 is a schematic diagram showing a transaction of environmental added value.

<Entire configuration of environmental value securitization system>
As shown in FIG. 1, the environmental value-added securitization system as a whole includes a plurality of participants' computers including a power generator terminal 21, a consumer terminal 31, a CIS terminal 41, an SM server 51, and a transaction server 61. Further, the block chain 1 is configured. Each computer is configured as a network terminal and includes well-known input means, storage means, display means, communication means (not shown), and a CPU for controlling them. As a communication method, cloud computing can be used using the Internet or a dedicated line.

<Block chain>
The block chain 1 of the present invention is a distributed ledger technology, and a plurality of individual transactions (transactions) are collected into a set called a block. This block has a continuously increasing list ordered like a chain. Since the addition of blocks to the list is performed simultaneously on each participant's terminal, the same list is stored in each participant's terminal. Each block includes a time stamp and a link to the previous block. Since the contents of a block depend on the hash value of the previous block, it is assumed that it is impossible to tamper with a block once added to the chain (unless all subsequent blocks are discarded). Once recorded, the data in the block cannot be retroactively changed. Therefore, the blockchain database is autonomously managed without a specific administrator by using a P2P network and a distributed time stamp server.

  The block list is recorded by one of the participants called the minor. Therefore, mining to determine a participant who is a minor is performed, and the determination method is generally Proof of Work (POW) determined by the answer time of a specific problem, or Proof of Staces determined by the amount of possession of virtual coins. (POS), etc., but it is also possible to use Proof of Importance (POI) in which participants who play an important role are fixed minor. In this embodiment, the environmental stock exchange is used for its processing capability and management. Six transaction servers 61 always perform minor functions.

  In general, blockchains also include permission-less types (permission-less type / open type) that do not require permission for participation, such as virtual currency. The block chain 1 of the present invention is of a private type, which is a permission type (permissioned type / closed type) in which permission for participation is given only to the environmental stock exchange 6.

  The block chain 1 of the present invention is a POI type block chain with a fixed minor, but has the following merits compared with a conventional so-called centralized server system. That is, since the block chain is a multiple ledger, it is highly secure against loss or alteration of records. Unlike the centralized system, it is not necessary to perform expensive multiplexing in order to ensure the trading server 61 of the environmental stock exchange 6 and the system introduction cost can be reduced.

  In addition, the fact that it is difficult to falsify the transaction history of blockchain is publicly recognized from the operation of virtual currency, etc., and it becomes possible to reduce public certification and labor costs related to national tax processing.

  Further, in the block chain 1 of the present invention, a smart contract is adopted in which each participant can not only directly view the transaction balance but also write / view the contract content itself in the block chain 1 in a complicated transaction. Therefore, the contract between each participant can be recorded and viewed. Therefore, each participant can easily check the existence of various contracts as needed, and the safety of transactions is greatly improved.

<Generator terminal>
The power generator terminal 21 is disposed on each power generator 2 that is a plurality of green power generators that generate green power GE with the solar panel 22 or the like.

<Customer terminal>
The consumer terminal 31 is arranged for each consumer 3 that is a plurality of power consumers such as a factory that desires to supply power EP.

<CIS terminal>
A CIS (Customer Information System) terminal 41 is arranged in a retail electric company 4 that retails electric power by signing a retail sales contract with each power generator 2. The CIS terminal 41 stores contract information of each power generator 2 that retails electric power. It also responds to information inquiries from the trading server 61 of the environmental stock exchange 6.

<SM server>
The SM server 51 is arranged in the smart meter control management center 5 and controls the smart meter 23 arranged in the power generator 2 to read the SM data, which is the power generation amount transmitted from the smart meter 23, and is necessary for a necessary terminal. It is a server computer that transmits various SM data.

<Transaction server>
The trading server 61 issues an environmental securities TEC corresponding to the environmental value-added EV based on the SM data placed on the environmental securities exchange 6 and received from the SM server 51. Also, virtual currency points Vpt are issued by exchanging with real currency. It is a server computer that forms, exchanges, and transfers a market. Moreover, it is always a minor of the block chain 1.

<Terminals of transmission / distribution companies / transmission / distribution companies>
As shown in FIG. 1, a power transmission / distribution company 7 that purchases power from a power generator 2 and a power transmission / distribution company 8 that supplies power to a consumer 3 are the blockchains that constitute the environmental value-added securitization system. It is not a required component. However, it can also be included in the block chain as a distribution destination such as paying an electric power fee with a virtual currency point Vpt.

<Smart meter>
The smart meters 23 and 32 are originally widely used for digitally measuring electricity, gas, water, and the like. However, in this embodiment, the meter further has a communication function, and autonomously sends the power amount to the transmission destination. A watt-hour meter that can be transmitted as SM data. The SM data is transmitted to the power transmission / distribution company 7 that purchases or supplies the power generated by the power generator 2 or the power transmission / distribution business 8 that the consumer 3 is supplied with, which is arranged in the power generator 2 or the consumer 3 And automate the meter reading work. For example, suitable smart meters include Mitsubishi Smart Meter (registered trademark) manufactured by Mitsubishi Electric Corporation.

  In addition, the use of electricity can be visualized through EMS (Energy Management System) or HEMS (Home Energy Management System). The electric power in each electric power generator 2 is controlled by these, for example, there are cases where power is transmitted during sunny days and the electric power is supplied during nighttime. The smart meter 23 detects and integrates both.

  In the present embodiment, the accumulated data of the power (kWh) measured by the smart meter is sent as SM data to the transaction server 61 of the environmental stock exchange 6 via the SM server 51 of the smart meter control management center 5 every 30 minutes. It is transmitted, and the supply and demand situation of the environmental value added EV is calculated.

<Blockchain participants>
Next, the participant in which each terminal of the block chain 1 is arranged will be described. In this specification, communication from each participant's computer to another participant's computer may be expressed as communication between the participants.

<Green power generator>
In the present embodiment, the power generator 2 that is a green power generator is cited as an example of solar power generation, but is not limited to solar power generation. Any green power generation that generates added value EV may be used.

  In the present embodiment, the power generator 2 includes a solar panel 22 and transmits the power generated here to the power transmission and distribution company 7 through a power transmission line. The power generation amount at this time is recorded in the smart meter 23.

  The power generator terminal 21 of the power generator 2 is a computer connected to a block chain as a private network, but it goes without saying that various transactions can be made by connecting to the Internet (not shown).

  The power generator 2 manages solar power generation, self-consumption power, etc. with HEMS, and the smart meter 23 automatically reads the transmitted power (kWh) every 30 minutes and transmits it to the SM server 51. As a transmission method, it is possible to perform wireless transmission by configuring a network with only smart meter terminals without using the network infrastructure by the wireless multi-hop method in addition to using the Internet. Further, there is no particular limitation on the communication means such as a 1: N wireless system using a wireless line of a communication carrier or a PLC (Power Line Communication) system using a commercial power line. Furthermore, SM data can be read from the smart meter 23 with a handy type maintenance handy terminal.

  In addition, when it is not generating electric power, such as at night, power is supplied from the power transmission and distribution company 7 by HEMS. Also in this case, it is recorded by the smart meter 23, SM information is transmitted to the power transmission and distribution company 7, and a fee is generated.

<Smart Meter Control Management Center>
The SM server 51 of the smart meter control management center 5 receives the smart meter data (SM data) transmitted from the smart meter 23. The SM data includes time information, identification ID, and power transmission amount (kWh) for 30 minutes.

The received SM data is transmitted to the trading server 61 of the environmental stock exchange 6 as a block chain terminal.
In addition, the sales / purchase information of the power of the power generator 2 is transmitted to the power transmission / distribution company 7 via the CIS terminal 41 of the retail electricity company 4.

<Retail electricity supplier>
The retail electricity company 4 concludes a power sales contract between the power generator 2 and the power transmission and distribution company 7 and manages it. For this reason, the CIS terminal 41 stores contract information in the storage means. The contract information includes the contract date, generator name, address, power generation equipment, and capacity. For a single purchase price, the purchase price under the fixed price purchase system (FIT) is determined by the fiscal year when the power generation equipment is certified and the capacity of the power generation equipment. For this reason, the transaction server 61 of the environmental stock exchange 6 also stores these pieces of information. If there is an inquiry from the trading server 61 of the environmental stock exchange 6, the CIS terminal 41 of the retail electricity supplier 4 determines whether the green power sold by the power generator 2 is subject to purchase by the fixed price purchase system (FIT). In order to determine whether the power generation facility is certified, information on the year when the power generation facility is certified and the capacity of the power generation facility is provided.

<Environmental stock exchange>
The environmental stock exchange 6 includes a trading server 61 as a terminal of the block chain 1 constituting the environmental value-added securitization system. The transaction server 61 receives the environmental value added EV sequentially based on the SM data sequentially transmitted from the smart meters 23 of the plurality of power generators 2 via the SM server 51 of the smart meter control management center 5. As this consideration, an environmental value-added point Ept is given to the power generator 2, and an environmental security TEC is issued as a proof thereof. However, the securities are not based on paper, but are electronic records indicating that the power generator 2 holds the environmental securities TEC in the block chain 1.

  Regarding this environmental value-added EV, the power generator 2 has concluded a sales contract for the environmental value-added EV together with the retail electric power company 4 in advance together with the power sales contract that has been concluded. The transaction server 61 collates the contract information of the power generator 2 with the CIS terminal 41, determines whether it is a target of the fixed price purchase system FIT, and is not an object of the fixed price purchase system FIT, and is an environment for purchasing at a variable price. When it is determined that the value added EV is obtained, a virtual environmental security TEC to which an environmental value added point Opt corresponding to the amount of power generation based on the SM data is issued is issued.

  When there is an order for selling the environmental securities TEC from the power generator terminal 21 of the power generator 2 during the trading time zone Tc (see FIG. 6), the transaction server 61 receives the environmental securities TEC and presents the exchange rate X that has been presented. Thus, virtual currency points Vpt are given according to the environmental value-added points Opt of the environmental securities TEC.

  On the other hand, when there is a purchase order for the environmental securities TEC from the consumer terminal 31 of the consumer 3 (securities buyer) to the environmental securities trading market, the trading server 61 requires the virtual currency points Vpt required at the presented exchange rate X. In exchange for the environmental securities TEC.

  The trading server 61 forms an environmental securities trading market based on the supply and demand in the simultaneous time zone Ta (see FIG. 6) from the orders of both the seller and the buyer, and uses the exchange rate X for the next trading time zone Tc. Is calculated.

  That is, the transaction server 61 responds to a sell order and a buy order at the exchange rate X presented as the trading time zone Tc. At the same time, the same sell order and buy order are the basis for calculating the next exchange rate X from the supply and demand relationship between the sell order and the buy order as the total time period Ta.

<Customer (buyer of securities)>
The customer 3 who is a securities purchaser is basically supplied with non-green power EC from the power transmission and distribution company 8. This electric energy is recorded by the smart meter 32 as with the power generator 2, and is transmitted as SM data to the SM server 51 of the smart meter control management center 5 every 30 minutes. The SM data is transmitted to the power transmission / distribution company 8, and the power transmission / distribution company 8 charges the amount of electricity used as a price based on this power usage.

  Since the generation of carbon dioxide is accompanied when the non-green electric power EP used is generated, the consumer 3 is responsible for the cost that is incurred as a cost to deal with this naturally. Therefore, we will fulfill our social responsibility by purchasing the added value of the environment generated by the generation of green power GE.

  As described above, the amount of power supplied from the power transmission / distribution company 8 of the consumer 3 is transmitted to the SM server 51 by the smart meter 32. This SM data is stored in the transaction server 61 of the environmental securities trader 6. Has also been sent. Therefore, in the transaction server 61, the environmental added value EV required by the consumer 3 is grasped.

  When the consumer 3 wants to obtain this environmental value added EV, the customer 3 is traded in the virtual environmental trading market EX in the trading server 61 of the environmental stock exchange 6, but the environmental value added EV is the environment of the environmental securities TEC. Transactions are performed by exchanging the value-added points Ept and the virtual currency points Vpt.

  The virtual currency point Vpt is traded with the actual currency (for example, Japanese yen) at a fixed exchange rate on the environmental stock exchange 6 as 1 yen = 1 Vpt. The consumer 3 obtains a virtual currency point Vpt necessary in real currency from the environmental stock exchange 6 in advance and obtains it in the block chain 1 in order to obtain an environmental value added point Ept corresponding to the necessary environmental value added EV. sign up.

<Transmission and distribution companies>
As described above, the power transmission / distribution company 7 concludes a contract between the power generator 2 of the green power GE and the retail power company 4, and purchases the green power GE generated by the power generator 2. In addition, when the power generator 2 in the power generator 2 exceeds the generated green power GE by the contract, power can be supplied from the power transmission / distribution company 7 by HEMS. Power transmission / distribution company 7 is not an indispensable participant of blockchain 1, but by joining blockchain 1, it is possible to pay for electricity charges with virtual currency points Vpt and to enhance its convenience. Can do.

<Transmission and distribution companies>
Here, the power transmission / distribution company 8 supplies the non-green power EP by thermal power generation other than renewable energy to the consumer 3 who is a large-scale electricity consumer. The transmission / distribution company 8 is not basically an essential participant of the block chain 1, but by participating in the block chain 1, it is possible to pay for the electricity fee with the virtual currency point Vpt and to enhance its convenience. Can do.

Of course, the power transmission / distribution business operator 7 and the power transmission / distribution business operator 8 do not preclude being the same power transmission / distribution business operator, but are distinguished in this specification for the sake of simplicity.
<Transactions with environmental value-added securitization systems>
Next, FIG. 3 is a diagram for explaining environmental value-added transactions by the environmental value-added securitization system of the present invention. A transaction procedure will be described with reference to FIGS. In addition, each computer performs processing, physical transmission, etc. for the transaction by a participant. Symbols S1, S2,... Are attached to the respective procedures.

<Environmental securities trading procedures (example)>
First, when the solar panel 22 and the smart meter 23 are ready, the power generator 2 concludes a power sales contract with the retail electric company 4 and transmits the contract information to the retail electric company 4 (S1). The contract information includes the contract date, generator name, address, power generation equipment, and capacity.

The retail electricity supplier 4 transmits the contract information for each power generator 2 to the environmental stock exchange 6 (S2).
When the power generator 2 generates power and transmits it to the power transmission / distribution company 7, the smart meter control and management center stores SM data as SM data by the smart meter 23 in units of 0.01 kWh. 5 (S3). The smart meter control management center 5 that has received the SM data aggregates and transmits this SM data to the environmental stock exchange 6 (S4).

  The environmental stock exchange 6 that has received the SM data receives the transfer from the power generator 2 of the environmental value-added EV generated according to the electric energy (kWh) in terms of 0.01 kWh = 0.01 Ept. Then, the corresponding environmental value-added point Ept is given to the power generator 2 at a ratio of green power generation amount 0.01 kWh = environmental value-added point Ept 0.01 point, and an environmental certificate TEC is issued and transmitted as a proof (S5). ).

  The environmental stock exchange 6 is preliminarily processed in the processing time zone Tb (see FIG. 6, here 30 minutes) on the basis of the results of selling orders and buying orders in the totaling time zone Ta (see FIG. 6, here 2 hours). The exchange rate X is calculated (S6). The calculated exchange rate X is presented to the power generator 2 and the consumer 3 (S7). The selling order (S8) and the buying order (S11) at the exchange rate X are accepted from this presentation during the trading time zone Tc (see FIG. 6, 2 hours here).

  The power generator 2 who wants to sell the environmental securities TEC places a selling order on the environmental stock exchange 6 (S8). When there is a sell order (S8), the environmental stock exchange 6 receives the environmental security TEC and transfers the environmental value-added EV (S9), and at the exchange rate X displayed when the order is received, A virtual currency point Vpt corresponding to the environmental added value point Opt of TEC is given (S10).

  On the other hand, the customer 3 (securities purchaser) who wants to obtain the environmental securities TEC places a purchase order on the environmental securities exchange 6 (S11). When there is a buy order (S11), a virtual currency point Vpt required according to the number of pt points of the buy order is requested at the exchange rate X presented at the time of order receipt (S12), and the virtual currency point Vpt is received. (S13), the environmental securities TEC is given to the consumer, and the environmental value added EV corresponding to the environmental value added point Opt is transferred (S14).

<Environmental securities trading market formation procedure>
FIG. 4 is a table showing the supply and demand balance between the environmental value added EV generated in the block chain 1 and the potentially required environmental value added EV based on the SM data received by the transaction server. FIG. 5 is a table showing the exchange rate X calculated based on the order quantity of the environmental securities TEC selling and buying orders in the trading of the environmental securities TEC. FIG. 6 is a time chart for explaining the total time zone Ta, the processing time zone Tb, and the trading time zone Tc in the procedure for forming the environmental securities trading market price. The procedure for forming the environmental securities trading market price (S6) will be described in detail with reference to FIGS.

<Demand and supply balance of ept generated in the block chain>
As shown in FIG. 4, the transaction server 61 uses the SM data received from the SM server 51 to determine the value added to the environment by the participants of the blockchain 1 based on the amount of power (kWh) generated by the green generators A, B, and C. The amount of EV generated (supply amount) is known. Therefore, based on the generated environmental value-added EV, it is grasped how many environmental value-added points Ept have been issued.

  On the other hand, the non-green power EP used by each of the X and Y consumers 3 is recorded by the smart meter 32 installed in each consumer 3, and this is fed back to the transaction server 61. It also grasps the number of points of the environmental value-added EV necessary for the consumer 3 to be considered to have used the complete green power GE. These are tabulated every 30 minutes. That is, the potential demand for the environmental value-added EV is known. This data is presented to the power generator 2 and the consumer 3 at the transaction server 61 every hour.

  In the present invention, the exchange rate X between the environmental value-added point Ept and the virtual currency point Vpt is determined based on the actual purchase order / sell order, but the exchange rate X is immediately determined based on the generated amount. It is not something. Therefore, this information is positioned as reference data for determining the supply and demand balance with respect to the timing of a buy order or a sell order. The power generators 2 of A, B, and C and the consumers 3 of X and Y determine the timing of selling orders and buying orders of the environmental securities TEC while observing this supply and demand balance. The next exchange rate X is determined by the balance of the number of orders.

<Calculation of exchange rate X>
FIG. 5 shows a selling order for environmental securities TEC of A, B, and C and a buying order for environmental securities TEC required by consumers of X and Y among the environmental value-added points shown in FIG.

  The order is divided into time zones such as “0: 00-0: 30” and “0: 30-1: 00” by the elapsed time every 30 minutes from the start of the transaction, for example. Sell orders and buy orders are registered for each time period. For example, in the time zone of “0: 00-0: 30”, power generator A places a selling order of 0.15 points, and power generator B places a selling order of 0.10 points. Further, the consumer X places a purchase order of 1.00 points, and the consumer Y places a purchase order of 2.00 points. In this way, the selling order and the buying order in the four time zones from the start of the transaction until the lapse of 2:00 are closed at 2:00, and the total time zone Ta of 0: 00-2: 00 (see FIG. 6). ) During the processing time period Tb (see FIG. 6) of “2: 00-2: 30”.

  In the example of this embodiment, the exchange rate X is basically obtained by dividing the number of points of a buy order by the number of points of a sell order. In Table 5, since the sell order (0.15 + 0.10 + 0.15 + 0.10 + 0.07) is a buy order (1.00 + 2.00 + 1.00 + 2.00 + 1.00), the exchange rate X = buy order / sell Order = 7.00 / 0.57≈12.28 (rounded to the second decimal place). Therefore, the exchange rate X = 12.28 is determined.

  Then, the exchange rate X is presented to the power generator terminal 21 and the consumer terminal 31 at 2:30. The buy and sell orders received in the trading time zone Tc (see FIG. 6) of 2: 30-4: 30 are exchanged for the virtual currency point Vpt by the environmental value TEC of the environmental securities TEC at this exchange rate X. Is done.

  In addition, for the sake of explanation, the calculation here was calculated with a simple inverse proportion of the value as an example, but for adjustment, it does not hinder the application of a coefficient or subtraction of a fixed amount such as a fee. It goes without saying that it may be based on a value calculation model.

  In addition, since the buy order / sell order for determining the exchange rate X and the buy order / sell order actually exchanged at the exchange rate X are different, there may be a margin or loss at the environmental stock exchange 6. The exchange rate X between the selling order and the buying order may be different, and this difference may be eliminated.

<Total time zone Ta, processing time zone Tb, and trading time zone Tc>
With reference to FIG. 6, next, such a transaction is demonstrated with a time chart. First, transactions between 0: 00-2: 00 in the first total time zone Ta1 are totaled between 2: 00-2: 30 in the processing time zone Tb1 by the method described above, and the exchange rate X1 is calculated. calculate. Then, it is presented to each power generator terminal 21 and each consumer terminal 31 when the elapsed time is 2:00. Then, in the selling order and the buying order received during 2: 30-4: 30 in the trading time zone Tc1, the environmental value-added point Ept is exchanged for the virtual currency point Vpt at the exchange rate X1.

  In parallel with this, the trading server 61 of the environmental stock exchange 6 performs the same trading for the next totaling time zone Ta2 between 2:00 and 4:00, similarly in the processing time zone Tb2 at 4: 00-4: The exchange rate X2 is calculated by counting during 30. Then, it is presented to each power generator terminal 21 and each consumer terminal 31 when the elapsed time is 4:00. Then, in the selling order and the buying order received during 4: 30-6: 30 in the trading time zone Tc2, the environmental value-added point Ept is exchanged for the virtual currency point Vpt at the exchange rate X2.

  In this way, the totaling time zones Ta1, Ta2, Ta3, Ta4. In addition, in the trading time zones Tc1, Tc2, Tc3, Tc4.

  Therefore, the power generator 2 and the consumer 3 always have a smooth exchange of all transactions at the constant exchange rate X that the environmental stock exchange 6 presents at the start of the trading time period Tc based on the past buy and sell orders. To be done.

  Note that there is a time difference between the determination of the exchange rate X and the actual exchange of the environmental value-added point Ept and the virtual currency point Vpt. In the trading time zone Tc, all buy orders and sell orders are received and exchanged. There may be a shortage of environmental securities TEC in the market due to the purchase of TEC. The environmental value-added EV that supports the environmental securities TEC is a substance that is generated by the generation of green power, so short selling is not desirable. Therefore, the environmental stock exchange 6 stocks sufficient surplus beforehand so that the environmental stock TEC does not run short.

<Relative transactions>
Basically, the consumer 3 purchases the environmental securities TEC from the power generator 2 via the trading server 61 of the environmental securities exchange 6. However, for example, there are cases where the consumer 3 desires a stable transaction continuously from a specific power generator 2 at a fixed amount directly. In such a case, a direct transaction contract (S15) may be exchanged directly between the specific power generator 2 and the specific consumer 3. Regarding the relative transaction, it is free to follow the exchange rate X presented by the environmental stock exchange 6 by an individual sales contract, or the exchange rate X may be fixed for a certain period.

  As shown in FIGS. 2 and 3, the specific power generator 2 delivers the environmental securities TEC to the specific consumer 3 (S16), and the consumer 3 receives the virtual currency point Vpt according to the individual contract. (S17). In this case, since the smart contract is adopted for the block chain 1, detailed records are surely left in the block chain 1 for both the contents of the individual relative transaction contract and the transfer of the environmental securities TEC and the virtual currency point Vpt. .

<Virtual currency point Vpt>
In the present embodiment, the power generator 2 that has obtained the virtual currency point Vpt can be exchanged for cash at the environmental stock exchange 6. It is also possible to use the virtual currency point Vpt for the settlement of the electricity bill in the over-purchased state. Furthermore, if there is a solar panel for power generation as a participant in the block chain 1, the power generator 2 can purchase the solar panel for power generation using the accumulated virtual currency points Vpt. .

According to the environmental value added securitization system of the above embodiment, the following effects can be obtained.
(1) According to the present embodiment, since the environmental securities TEC that proves possession of the environmental value-added EV are virtually issued and granted in the block chain 1, the power generator who is a participant in the block chain 1 2. The consumer 3 can easily view the record and prevent falsification.

  (2) Since the environmental value-added EV that cannot be seen is securitized as environmental securities TEC on the network, it can be visualized on the network and can be traded easily and instantaneously.

  (3) Since the exchanged value X pt and the virtual currency point Vpt of the environmental securities TEC are continuously exchanged at the exchange rate X while presenting the confirmed exchange rate X, the green power generator 2 And the electric power consumer 3 can buy and sell the environmental securities TEC on the condition that the appropriate exchange rate X reflecting the supply and demand situation of the environmental securities TEC is fixed.

  (4) In this embodiment, the amount of green power generated by the power generator 2 is transmitted by the smart meter 23 to the environmental stock exchange 6 that is a participant in the block chain 1 every 30 minutes. As a result, the environmental value-added EV generated by the power generator 2 is sequentially securitized as the environmental server TEC is issued by the transaction server 61 and includes a certain environmental value-added point Ept corresponding to the environmental value-added EV. Trading becomes easy.

  (5) By using the smart meter 23, it is possible to grasp the amount of power every predetermined time, for example, every 30 minutes, in units of 0.01 kWh. The environmental value added EV can be securitized.

(6) The environmental securities TEC transaction does not deal with an actual paper certificate, but is basically a record on the virtual block chain 1, and therefore is easy to trade and manage.
(7) Since trading of the environmental securities TEC is performed using the virtual currency point Vpt in the block chain 1, it can be performed regardless of actual cash. Since the virtual currency point Vpt can be exchanged for cash at the environmental stock exchange 6, the virtual currency point Vpt and cash necessary for the transaction can be exchanged with each other.

  (8) In this embodiment, the power transmission / distribution company 7 and the power transmission / distribution company 8 can participate as participants in the block chain 1. In this case, the electricity fee is settled with the virtual currency point Vpt. be able to.

  (9) Furthermore, by making the solar panel for power generation a participant in the blockchain 1, the power generator 2 securitizes the environmental value-added EV obtained by green power generation and exchanges it for virtual currency points Vpt. You can make it possible to purchase solar panels for power generation.

  (10) In the present embodiment, the order quantity is preliminarily calculated based on the quantity of selling orders and buying orders in a predetermined total time period Ta, the exchange rate X is calculated in the processing time period Tb, and then in the trading time period Tc. Since buy orders and sell orders are received uniformly at this constant exchange rate X, even if there are a large number of orders, processing can be immediately performed.

(11) The trading time zones Tc1, Tc2, Tc3, Tc4... Are continuous and can be traded at all times, so that the order can be processed immediately without delaying the order.
(12) Further, the total time periods Ta1, Ta2, Ta3, Ta4... Are continuous, and the trading time periods Tc1, Tc2, Tc3, Tc4. Although the order between the bands Ta and the order in the trading time zone Tc in which they actually buy and sell are different, they are averaged by continuing long-term trading.

  (13) Since the same exchange rate X is always displayed within one trading time zone Tc and trading can be performed immediately, both the power generator 2 and the consumer 3 can make a transaction with a firm transaction result. it can.

  (14) Since the block chain 1 is a multiple ledger, it is not necessary to perform expensive multiplexing in order for the trading server 61 of the environmental stock exchange 6 to be complete, unlike the conventional centralized system. Introduction cost can be reduced.

(15) The fact that the transaction history of the block chain 1 is difficult to falsify is publicly recognized from the operation of virtual currency, etc., and it is possible to reduce proofs related to national tax processing and personnel costs.
(16) Further, in the block chain 1 of the present embodiment, a smart contract is employed in which each participant can not only directly view the transaction balance but also write the contract content itself into the block chain 1 in a complicated transaction. As a result, contracts between each component can be recorded and viewed. Therefore, each participant can easily confirm the existence of various contracts, and the safety of transactions is greatly improved.

  (17) Therefore, even a partner who does not know can use a smart contract to record a sales contract and cannot falsify it, so that a relative transaction or the like can be performed with peace of mind. In the case of a relative transaction, a specific consumer can continue the transaction at a fixed amount without being influenced by the fluctuation rate from a specific power generator.

  (18) In this embodiment, in the participants of the block chain 1, there are required amounts of the environmental value added EV generated in the power generator 2 by the smart meter 23 and the environmental value added EV generated in the consumer 3 by the smart meter 32. The transaction server 61 presents each power generator 2 and each consumer 3 at regular intervals. For this reason, each power generator 2 and each consumer 3 can determine the selling order and buying order timing of the environmental securities TEC while looking at the supply and demand relationship of the environmental securities TEC.

  It goes without saying that the above embodiments can be added, omitted, and replaced by those skilled in the art without departing from the technical idea of the present invention.
