Description

Apparatus and method for authenticating power consumption history based on blockchain

The present invention relates to a technology for storing power usage history based on block chain and automatically issuing a certificate based on block chain when authentication for power usage is required.

Renewable energy is pollution-free energy that can replace existing fossil fuels and nuclear power, and is generally understood as a component of alternative energy. For example, it refers to energy obtained through solar heat, photovoltaic power generation, biomass, wind power, geothermal and marine energy, and the like.

In addition, whenever electricity is produced through fossil fuels and nuclear power, natural destruction is increasing, and the risk of depletion of fossil fuels and nuclear resources is emerging.

In modern times, as interest in renewable energy increases, a campaign is taking place to use electricity generated through eco-friendly renewable energy sources such as RE100 for 100% of the electricity used by companies.

Meanwhile, in countries or regions where infrastructure and legal systems for renewable energy are not in place, the requirements for obtaining a renewable energy use certification (RE100 initiative, etc.) have not been formed. In addition, although large domestic companies are declaring or considering participation in RE100, the domestic renewable energy market is small and significant results are not being achieved due to legal restrictions on electricity trade.

The present invention distributes and stores data on the power consumption of power consuming objects through block chain technology, generates a certificate based on the stored data, and transfers ownership to a customer who needs authentication. The purpose of this is to ensure that authentication can be performed reliably and easily in terms of security.

In addition, in step (a), if there are a plurality of power consuming objects, the power generating object or server can generate a certificate by dividing the amount of power produced during a specific period into preset transaction units.

In addition, the transaction unit may be divided into either the number of power consumption objects or the minimum transferable power unit.

Also, in step (c), the ownership of the certificate corresponding to the power consumption requested by the second user terminal among all the generated certificates may be changed to be owned by the second user terminal and then sold.

In addition, in step (c), if the power production amount of the generated certificate and the power consumption requested by the second user terminal do not match, the original certificate is discarded and the certificate is regenerated according to the ordered power consumption, and the It can be sold after changing the ownership to the name of the ordered object.

In addition, in step (c), the purchase information and sales information matching the condition are searched, but the condition of the matching is whether the power generation object corresponds to a power consumption object receiving the power supplied, and the searched sales information is used as the second The transaction of the ownership change contract may be triggered depending on whether the second user terminal has been transferred to the user terminal and confirmed the purchase.

In addition, after step (c) (d), the method may include providing a report on the certificate to the second user terminal to which the certificate of ownership has been transferred.

In addition, the report can be automatically generated in the form of comprehensively recording the amount of renewable energy usage for a preset period and its certificate by using the information and certificate of the block chain on the node that attempted authentication.

In addition, after step (d) (e) receiving a power consumption authentication request for a specific power consuming object from the institution terminal; (f) retrieving certificate details for a specific power consuming object; and (g) providing the search result to the institution terminal to verify the use of renewable energy of a specific power consuming object, wherein the institution terminal may refer to a terminal belonging to an institution for authenticating the use of renewable energy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art can easily implement them. However, the present invention may be embodied in several different forms and is not limited to the embodiments described herein. And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the specification.

Throughout the specification, when a part is "connected" with another part, this includes not only the case of being "directly connected" but also the case of being "electrically connected" with another element interposed therebetween. . In addition, when a part "includes" a certain component, it means that other components may be further included, rather than excluding other components, unless otherwise stated, and one or more other components may be included. It should be understood that the existence or addition of features or numbers, steps, operations, components, parts, or combinations thereof, is not precluded in advance.

The following examples are detailed descriptions to help the understanding of the present invention, and do not limit the scope of the present invention. Accordingly, an invention of the same scope performing the same function as the present invention will also fall within the scope of the present invention.

Throughout the specification, the server 100 may refer to a device that authenticates power consumption details based on a block chain.

Referring to FIG. 1 , according to an embodiment of the present invention, a system may include a server 100 , a first user terminal 210 , and a second user terminal 220 . At this time, although not shown in the drawing, the server 100 , the first user terminal 210 , and the second user terminal 220 may be interconnected by wire or wirelessly through a communication network.

According to an embodiment of the present invention, the first user terminal 210 and the second user terminal 220 may be terminals of an object that intends to sell a certificate for power production or purchase a certificate for power usage. there is.

On the other hand, a plurality of objects may participate in the blockchain network 500 . At least one of the power generation object 300 , the power consumption object 400 , the power production amount detection device 310 , the power consumption detection device 410 , and the server 100 participates as a node in the block chain network 500 . can

According to an embodiment of the present invention, the amount of power produced by the power generating object 300 or the power consumption used by the power consuming object 400 is distributed and stored in a block chain.

By being distributed and stored in each object in the block chain network 500, the security and verification level of each generated information is increased, and the calculated block chain data can be divided and stored in several objects. For example, in addition to the power generation object 300 and the power consumption object 400, it may be stored in an object monitoring it or other separate objects, and an object for block chain recording may exist separately.

In this case, the power consumption object 400 means an object that receives power from the power generation object 300 and consumes power. For example, a general household or office may have a power consuming object 400 to receive power produced directly from the power generating object 300, and a factory may receive and use the surplus power remaining after a specific complex consumes it. Therefore, the power consumption object 400 may exist.

In addition, the power generation object 300 may correspond to an object that generates power (energy). For example, it is a large-scale power production object 300 such as a hydroelectric power plant, a thermal power plant, a new renewable energy production power plant (eg, a solar power plant, a geothermal power plant, a wind power plant, etc.), or a small unit such as a solar photovoltaic module It may be a power generation object 300 of

A large-scale power production object 300 such as a hydroelectric power plant, a thermal power plant, or a renewable energy production power plant (eg, a solar power plant, a geothermal power plant, a wind power plant, etc.), or a small-scale power production object such as a photovoltaic module (300) can be managed by grouping it as the first power production object, and conversely, a power production method that does not interest users using fossil fuels, such as thermal power generation, can be classified and managed as a second power production object. In addition, things that are not included in the above two categories (eg, energy flowing into the energy complex from the outside) may be classified as the third power generation object. Meanwhile, in addition to these criteria, arbitrary classification criteria may be further added. For example, classification conditions for each configuration may be formed in various ways as needed, such as a renewable energy group, a renewable energy group excluding biomass, and a new and renewable energy group including fuel cells. Criteria for classifying power generation objects may be set in various ways, and it is not necessarily limited to the example described in the present invention.

On the other hand, the power production object 300 and the power consumption object 400 are provided with a power production amount detection device 310 and a power consumption amount detection device 410, respectively, to check the amount of power produced by the power production object 300 Thus, it is provided to the server 100 or the block chain network 500, or the amount of power consumed by the power consuming object 410 is checked and provided to the server 100 or the block chain network 500.

That is, the power production amount detecting device 310 and the power consumption detecting device 410 are a kind of smart meter, which measures the production or consumption of power and transmits the data to the server 100, the first user terminal ( 210), the second user terminal 220 and the block chain network 500, and the like.

Next, when a specific condition is met, the server 100 generates a certificate for the power production stored in the block chain through a smart contract, and then receives the sales information for the certificate from the first user terminal 210. It is registered and set to be exposed to the second user terminal 220 . In this case, the certificate generated through the smart contract may be the server 100 or the power generation object 300 itself. That is, depending on which object has the authority to execute the smart contract, there is a slight difference in the certificate creation process. For example, when the smart contract is executed with the account of the server 100, it may be implemented to generate certificates of all users, and the smart contract is executed with the account of the server 100 to generate certificates of all users, and power Even with the account of the production object 300, only its own certificate can be generated. Meanwhile, depending on the implementation method, only the power generation object 300, not the server 100, may be implemented to generate its own certificate.

At this time, the certificate may be transferred as a certificate for energy production or use. The certificate includes the type of power produced (whether it is renewable energy or external energy, etc.), identification information on the power generation object, information on the amount of power produced, and information on the power generation time. For example, when object A produces a certificate for renewable energy production in a physically separated power grid, object B that consumes the renewable energy transfers the ownership of the certificate and requires subsequent management agency certification can be used

Thereafter, when the purchase information for the certificate is received from the second user terminal 220 , the server 100 changes the ownership of the certificate through the ownership change contract.

Meanwhile, the server 100 may correspond to a general local server or may be formed to correspond to any one of the cloud servers. Accordingly, the scope of the present invention is not limited because there may be various ways of implementing the server 100 .

According to an embodiment of the present invention, the first user terminal 210 may correspond to a terminal of a user having ownership of the certificate. In general, it may be a terminal belonging to the power generating object 300 that generates power.

The second user terminal 220 may correspond to a terminal of a user who wants to take ownership of the certificate. In general, it may be a terminal belonging to the power consuming object 400 that consumes power.

For example, when the first user who has produced a certain amount of renewable energy provides sales information about the certificate to the server 100 through the first user terminal 210, the second user terminal 220 who wants to authenticate the use of renewable energy ) transmits the purchase information to the server 100, and when the purchase information and the sale information match, the server 100 changes the ownership of the certificate, thereby providing the certificate with the changed ownership to the second user terminal.

Also, the first user terminal 210 and the second user terminal 220 refer to communication terminals capable of using a terminal application in a wired/wireless communication environment. Here, the user terminal 200 may be a user's portable terminal. In FIG. 1 , the first user terminal 210 and the second user terminal 220 are illustrated as a smart phone, which is a type of portable terminal, but may be a terminal such as a desktop, and other various terminals with a built-in CPU. can be

Meanwhile, the communication network serves to connect the server 100 and the first user terminal 210 and the second user terminal 220 . That is, the communication network refers to a communication network that provides an access path so that the first user terminal 210 and the second user terminal 220 can transmit and receive data after accessing the server 100 . The communication network is, for example, wired networks such as LANs (Local Area Networks), WANs (Wide Area Networks), MANs (Metropolitan Area Networks), ISDNs (Integrated Service Digital Networks), and wireless networks such as wireless LANs, CDMA, Bluetooth, and satellite communication. may be encompassed, but the scope of the present invention is not limited thereto.

Referring to FIG. 2 , the server 100 according to an embodiment of the present invention includes a communication module 110 , a memory 120 , a processor 130 , a database 140 , an order system module 150 , and a certificate management module. (160).

In detail, the communication module 110 interworks with the communication network to the server 100 , the first user terminal 210 , the second user terminal 220 , the block chain network 500 , the power production amount sensing device 310 , and the power consumption A communication interface required to provide a transmission/reception signal between the sensing devices 410 in the form of packet data is provided. Furthermore, the communication module 110 receives a data request from the first user terminal 210 , the second user terminal 220 , the block chain network 500 , the power production amount detection device 310 , and the power consumption amount detection device 410 . Receive and transmit data in response thereto.

Here, the communication module 110 may be a device including hardware and software necessary for transmitting and receiving signals such as control signals or data signals through wired/wireless connection with other network devices.

In the memory 120, a program for authenticating power consumption details based on a block chain is recorded. In addition, the processor 130 performs a function of temporarily or permanently storing the processed data. Here, the memory 120 may include magnetic storage media or flash storage media, but the scope of the present invention is not limited thereto.

The processor 130 controls the entire process of authenticating power consumption details based on a block chain as a kind of central processing unit. Each step performed by the processor 130 will be described later with reference to FIGS. 3 and 4 .

Here, the processor 130 may include all kinds of devices capable of processing data, such as a processor. Here, the 'processor' may refer to, for example, a data processing device embedded in hardware having a physically structured circuit to perform a function expressed as a code or command included in a program. As an example of the data processing apparatus embedded in the hardware as described above, a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated (ASIC) circuit) and a processing device such as a field programmable gate array (FPGA), but the scope of the present invention is not limited thereto.

The database 140 stores data on power production or consumption received from each object.

At this time, each data may be stored through a block chain technique. As an optional embodiment, the block information is stored in the block chain network 500 in which the block information is stored, and the block chain network 500 may be any one of a public block chain network, a consortium block chain network, and a private block chain network, and if necessary Data is stored in another blockchain network 500 .

Although not shown in FIG. 2 , some of the data on power production or consumption may be stored in a database (not shown) physically or conceptually separated from the database 140 .

The order system module 150 manages the sale information received from the first user terminal 210 and the purchase information received from the second user terminal 220 , and matches each sale information and purchase information to sell for a certificate will manage

The certificate management module 160 corresponds to a module that performs comprehensive management, such as creating and revoking a certificate and changing ownership through a smart contract.

In an optional embodiment, the database 140 , the order system module 150 , and the certificate management module 160 may be implemented through separate objects. For example, data on the amount of electricity production or consumption is not a database of the server 100, but a power production object

It is stored in the database 140 of the terminal belonging to 300 or the power consumption object 400, a sales server that professionally manages sales orders and external orders is separately provided, or a module for certificate management is installed in the power production object ( 300) or may exist as an independent object in other external areas.

Referring to FIG. 3 , the server 100 records power production in a block chain (S310).

Specifically, in the server 100, the power generation object 300 records and distributes the power production in a block chain. In this case, as the storage technology, distributed ledger technology may be applied.

At this time, as described above, the power consumption is measured by the power consumption detection device 410 provided in the power consumption object 400 , and the power production is measured by the power production amount detection device 310 provided in the power generation object 300 . ) can be measured by

In addition, the power production measured by the power production amount detecting device 310 and the power consumption measured by the power consumption detecting device 410 are recorded in each node in the block chain network 500 .

Next, the server 100 generates a certificate for the power production (S320).

Specifically, the server 100 generates a certificate for the power production stored in the block chain through a smart contract.

At this time, a smart contract is a script that is implemented as a contract code and executes the contract when a specific condition is satisfied.

In addition, in step S320 , the server 100 determines that any one of the nodes included in the block chain network 500 is a smart contract transaction when the power production measured by the power production amount detection device 310 corresponds to a preset condition. to generate a certificate for power production. At this time, although the subject that sets the smart contract is described as the server 100 above, the power generation object 300 may directly set the smart contract to generate a certificate depending on the situation.

In this case, in an optional embodiment, the server 100 may generate a certificate by invoking a smart contract based on the data of the node of the power generating object 300 and the power production for each preset period. For example, a certificate is generated based on data of the amount of electricity produced in a simple cycle of one day or the amount of electricity that the power consuming object 400 uses for one day.

In another optional embodiment, the server 100 determines the power production or power consumption of each node over time when the power generating object 300 produces a preset amount of power or the power consuming object 400 consumes a preset amount of power. Based on the data, a smart contract can be triggered to generate a certificate. For example, the moment the power generation object 300 produces power of 1000 kW, a certificate is generated based on data on power production of 1000 kW and data on time consumed in power production.

Meanwhile, a certificate may be automatically generated based on a preset time. For example, it could automatically generate a certificate for one week's electricity production automatically every Friday at 1:00 PM.

As another optional embodiment, if a plurality of power consuming objects 400 exist, the power generating object 300 or the server 100 divides the amount of power produced during a specific period into preset transaction units to generate a certificate. can

For example, the transaction unit divides the power production by either the number of power consuming objects 400 or the minimum transferable power unit and sells it. For example, in the case of dividing and selling 100 kW of power, 10 10 kW certificates are generated and sold to the nodes of 10 power consuming objects 400 , respectively.

Specifically, in step S340 to be described later, the ownership of the certificate is changed to the ownership of the second user terminal 220 by the quantity corresponding to the power consumption requested by the second user terminal 220 among all the generated certificates. will be. For example, 10 certificates are generated by dividing 100 kW by 10 kW each, and 4 certificates are sold to customers who need ownership of 40 kW of power to provide 40 kW of rights.

Accordingly, through the process performed in step S320 , the initial ownership of the certificate belongs to the power generation object 300 .

Next, when the server 100 receives the sales information for the certificate, it registers the sales information in the ordering system (S330).

Specifically, sales information for the certificate is received from the first user terminal 210 associated with the power generation object 300 , and the server 100 registers the received sales information.

As a further embodiment, the server 100 may transmit a sales interface for selling the certificate to the first user terminal 210, and through the sales interface, the first user terminal 210 may transmit the power of the power to transfer the right. Data such as type, quantity, and production time are set, and the certificate matching the condition selected by the first user terminal 210 is searched for. In addition, when a plurality of pieces of sales information are received from the plurality of first user terminals 210 , they are listed and provided.

Finally, when the purchase information of the certificate is received, the server 100 changes the ownership of the certificate through the ownership change contract (S340).

Specifically, when the purchase information of the certificate is received from the second user terminal 210 associated with the power consuming object 400 and the purchase information and the sale information match, the server 100 transfers the ownership of the certificate through the ownership change contract. will change

At this time, the server 100 searches for the sale information matching the purchase information and the condition, and transmits the searched sale information to the second user terminal 220 , depending on whether the second user terminal 220 confirms the purchase. By triggering the transaction of the ownership change contract, the certificate is transferred. In this case, the matching condition corresponds to whether the power generating object 300 corresponds to a power consuming object receiving the supplied power. For example, it is assumed that the first power generating object supplies power to a plurality of power consuming objects in the first complex, and the second power generating object supplies power to a plurality of power consuming objects in the second complex. , so that the power consuming object of the first complex does not purchase the certificate of the second power producing object, but only the certificate of the first producing object. Therefore, when referring to the identification information of the power generating object and the identification information of the power consuming object, if the power supply/supply relationship matches each other, it is considered that the purchase information and the sales information match each other.

Therefore, as an additional embodiment, the server 100 transmits a purchase interface for receiving purchase information to the second user terminal 220 . The second user terminal 220 may transmit purchase information to the server 100 by inputting conditions such as the type, amount, and production time of the power desired to be transferred through the purchase interface.

In addition, in step S330, if the power production of the generated certificate and the power consumption requested by the second user terminal 220 do not match, the original certificate is discarded and the certificate is regenerated according to the ordered power consumption, After changing the ownership of the regenerated certificate to the name of the ordered object, it can be sold. For example, if there is a customer who wants to transfer 40 kW of rights, but a certificate of 100 kW has already been created, the 100 kW certificate is revoked and 40 kW and 60 kW certificates are generated respectively, and the 40 kW certificate is transferred (i.e. change of ownership) ) will do.

Referring to FIG. 4 , the server 100 provides a report on the certificate after step S340 ( S350 ).

Specifically, the server 100 provides a report on the certificate to the second user terminal 220 to which the certificate of ownership has been transferred.

At this time, it means that the report is automatically generated in the form of comprehensively recording the renewable energy usage for a preset period and its certificate by using the information and certificate of the block chain on the node that attempted authentication.

Next, the server 100 receives a specific power consuming object authentication request from the institution terminal (S360).

Specifically, it means that the server 100 requests power consumption authentication for a specific power consuming object from an institution terminal, and the institution terminal means a terminal belonging to an institution for authenticating the use of renewable energy.

Next, the server 100 searches for certificate details related to the specific power consumption object 400 ( S370 ), and the server 100 provides the search result to the institution terminal, and reproduces the specific power consumption object 400 . The energy usage is verified (S380).

At this time, the server 100 checks whether the report matches either the power consumption or the certificate recorded in the block chain.

As a further embodiment, the report may be provided in the form of a block chain including data within the period requested by the institutional terminal, or may be provided in the form of graphs and texts that can be checked with the naked eye, so that the second user terminal 220 in advance You can choose this.

The description of the present invention described above is for illustration, and those of ordinary skill in the art to which the present invention pertains can understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a dispersed form, and likewise components described as distributed may also be implemented in a combined form.
