As described above, when the first user wants to purchase power, the external server 200 may be a server that serves as an intermediate medium.

The external server 200 may perform a role of transmitting information on coins used when the first user purchases power to at least one node constituting the blockchain network 400.

For example, the external server 200 may transmit information that the first user has purchased power by consuming a certain amount of coins to at least one node constituting the blockchain network 400. In this case, a plurality of nodes constituting the block chain network 400 may record the received information in the block based on the consensus algorithm as the above-described information is received. Here, the blockchain address may mean a wallet address in the blockchain network where the user's coin is stored.

Meanwhile, the power management server 300 may mean a server used by a power supplier. However, the present invention is not limited thereto, and a server used by a government agency that supplies power may be the power management server 300.

In the present disclosure, the power management server 300 receives first information on power purchase of a first user who wants to purchase power from the external server 200, and supplies power to the first user based on the first information. You can perform an operation such as doing. A detailed description of this will be described later with reference to FIG. 2.

Power management server 300 may include any type of computer system or computer device, such as, for example, microprocessors, mainframe computers, digital processors, portable devices and device controllers, and the like.

The power management server 300 may include a processor 310, a storage unit 320, a communication unit 330, and a power supply unit 340. However, since the above-described components are not essential to implement the power management server 300, the power management server 300 may have more or fewer components than the components listed above. Here, each of the components may be configured as a separate chip, module or device, or may be included in one device.

The account management unit 311 may update the amount of coins stored in the first virtual wallet of the first user based on the power purchase information of the first user. Here, the first virtual wallet may mean the wallet address of the first user managed by the power management server 300. The coins managed in the first virtual wallet may correspond to the amount of power to be supplied to the power supply associated with the first user. The first virtual wallet may be an address different from the block chain address of the first user managed by the block chain network 400 (ie, the block chain address managed by the first user terminal 100).

Specifically, information on the amount of coins stored in the first virtual wallet of the first user may be stored in the storage unit 320 of the power management server 300. When the account management unit 311 receives the first information on the power purchase of the first user from the external server 200 (or the first user's request from the blockchain address corresponding to the wallet of the first user terminal 100) 1 In the case of receiving the first information indicating that the coin has been transmitted to the block chain address corresponding to the virtual wallet), using the first information, the second information regarding the amount of the first coin currently being stored in the first virtual wallet of the first user Information can be updated.

For example, the first coin may be a coin having the same value as a cash product, or a coin in which a proportional (inversely proportional) relationship is formed with the value of the cash product. However, it is not limited thereto. In this case, the value of the first coin may be pre-stored in the storage unit 320 of the power management server 300. However, it is not limited thereto.

In conjunction with the power management server 300 managing virtual wallets of each of the plurality of users, transfer details of coins of each of the plurality of users may be stored in the blockchain network 400. In this case, since it is difficult for any subject to modify the information recorded in the determined block due to the nature of the blockchain technology, the amount of coins owned by each of the plurality of users can be prevented from being forged by hacking.

Meanwhile, the account management unit 311 may also update the amount of change in coins stored in the server wallet of the power management server 300. Here, the server wallet may mean a wallet address of the power management server 300 managed by the account management unit of the power management server 300. In addition, the server wallet may be an address different from the blockchain address of the server managed in the blockchain network 400.

Specifically, information on the amount of coins stored in the server wallet of the power management server 300 as well as the first virtual wallet of the first user may be stored in the storage unit 320 of the power management server 300. .

For example, when the amount of coins stored in the server wallet stored in the storage unit 311 is increased, the account management unit 311 may compare the amount of coins stored in the server wallet managed by the blockchain network 400. . In addition, when the account management unit 311 recognizes that the compared amount of coins is the same, it may determine that the increased amount of coins is maintained in the server wallet.

In addition, when it is recognized that the compared amount of coins is not the same, the account management unit 311 may roll back the amount of coins stored in the server wallet stored in the storage unit 320 to the amount of coins before increasing. I can. A detailed description of this will be described later with reference to FIG. 2.

Meanwhile, the coin change recognition unit 312 may recognize whether the amount of the first coin currently being stored in the first virtual wallet changes. A detailed description of this will be described later with reference to FIG. 2.

When the coin change recognition unit 312 recognizes that the amount of the first coins currently stored in the first virtual wallet has changed, it may recognize the first amount of power to be supplied to the first user based on the changed amount of coins.

Specifically, mapping information may be stored in the storage unit 320. Here, the mapping information may be information on how much power can be provided when how much coin is used. The coin change recognition unit 312 may recognize the first amount of power corresponding to the changed amount of coins by using the mapping information stored in the storage unit 320. In addition, the coin change recognition unit 312 may transmit power amount information about the first amount of power to the power supply unit 340.

Meanwhile, the storage unit 320 may include a memory and/or a permanent storage medium. Memory is a flash memory type, hard disk type, multimedia card micro type, card type memory (for example, SD or XD memory, etc.), RAM (Random Access).

The communication unit 330 may include at least one of a mobile communication module, a wired Internet module, and a wireless Internet module.

The power supply unit 340 may supply power to a power supply associated with the first user. As another embodiment, the power supply unit 340 determines to supply power to a power supply associated with the first user, and the actual power supply may be performed through another entity.

Specifically, when it is recognized that the updated second information is valid, the account management unit 311 may transmit a signal indicating that the updated second information is valid to the power supply unit 340. In this case, the power supply unit 340 may recognize that the updated second information is valid as the signal is received. When the power supply unit 340 recognizes that the second information is valid, the power supply unit 340 may recognize the power amount information on the first amount of power to be supplied to the first user based on the first information about the power purchase of the first user. Here, the power amount information may be information transmitted by the coin change recognition unit 312 to the power supply unit 340. As the power supply unit 340 recognizes the power amount information, the power supply unit 340 may supply power to a power supply related to the first user based on the power amount information. A detailed description of this will be described later with reference to FIG. 2.

Power in the present disclosure may mean energy that can be supplied to a power supply related to the first user through the power management server 300. However, although expressed as power in the present disclosure, energy that can be supplied to the first user may include gas and water as well as power.

In some embodiments of the present disclosure, the power supply of the first user may include a meter or a smart meter installed in the home of the first user. The power supply may determine power consumption for home appliances in the home of the first user and/or a cost corresponding to the power consumption, and perform and manage power supply to the home appliances.

The power supply of the first user may correspond to the first virtual wallet of the power management server 300. Therefore, based on the amount of power corresponding to the coin of the first user managed in the first virtual wallet and the amount of power determined by the power supply of the first user, the power management server 300 supplies power to the first user. Or you can decide to block.

The blockchain network 400 is a network including a plurality of nodes, and nodes included in the blockchain network 400 may be operated by a blockchain core package according to a hierarchical structure. The above structure defines the structure of the data handled by the blockchain network 400, a data layer that manages the data, and performs mining to verify the validity of the block and generates a block, and the commission paid to the miner during the mining process. A consensus layer in charge of processing, a P2P network protocol, a hash function, a common layer implementing and managing digital signatures, encoding and common storage, and an application layer in which various applications are created, processed, and managed may be included.

Further, according to some embodiments of the present disclosure, a power management server 300 may be included in a node included in the blockchain network 400.

Meanwhile, in some embodiments of the present disclosure, a plurality of nodes included in the blockchain network 400 may be a full block chain node or a light weight node.

A full block chain node can contain all block information from the first block of the block chain to a block that is currently newly created. In addition, the full blockchain node collects and stores all blockchain information, and can verify the received block to add a new block.

The Lightweight Node does not have the original of all block information, and may include only header information. In order for the Lightweight Node to verify the transaction, it can perform Simple Payment Verify (SPV).

For example, a lightweight node can request block information from a full blockchain node, and the authentication content of a transaction can be verified through Merkle Root.

However, for convenience of explanation, it is assumed that a plurality of nodes included in the block chain network 400 are full block chain nodes.

A block is a unit in which information described in some embodiments of the present disclosure is stored in the block chain network 400, and may form a block chain by being connected to adjacent blocks.

Since at least one piece of information is recorded in a block using the consensus algorithm of the blockchain technology, the effect of preventing hacking of the power management system occurs.

Meanwhile, in the present disclosure, the structure of the blockchain network 400 may be a public type or a private type. In the case of the public blockchain network 400, there is a disadvantage that it is inefficient in terms of consensus time, transaction processing speed, and efficiency of use of computing resources, since it is necessary to perform verification work on all nodes to verify transactions. Because the participation of the data is possible, there may be an advantage in the transparency and integrity of the stored data. In addition, in the case of a private (or consortium) block chain, since the operating entity is clear, there is an advantage of being efficient in terms of consensus time, transaction processing speed, and efficiency of use of computing resources, but transparency about the transaction processing process and results. There may be advantages in terms of

The consensus algorithm in this disclosure may be preferably a private or consortium-type blockchain network in order to improve the user experience through efficient use of computing resources and increase in transaction processing speed, but is not limited thereto, and depends on implementation aspects. If you want to further emphasize the transparency of power management information, the public type may be used as the consensus algorithm.

In the present disclosure, the power management server 300 may transmit a query or a transaction to the blockchain network 400. Here, the query may be used to inquire information stored in the blockchain network 400. In addition, the transaction in the present disclosure may be used to perform an update (modification/change/delete/add) on data recorded in the blockchain network 400.

You can enter in Here, the blockchain address may mean a wallet address in the blockchain network 400 in which the coin of the first user is stored. When the first user inputs information about his block chain address and the amount of coins into the first user terminal 100, the first user terminal 100 provides information on the block chain address of the first user and the amount of coins. Information may be transmitted to the external server 200. When the external server 200 receives information on the block chain address of the first user and the amount of coins from the first user terminal 100, the external server 200 generates first information on the power purchase of the first user, and the power management server It can be sent to 300. In this case, the communication unit 330 of the power management server 300 may receive first information on the power purchase of the first user from the external server 200.

As another example, when the external server 200 is a server that directly provides a platform related to power purchase to a user, the display unit of the external server 200 may display a screen related to power purchase. The first user may input information about his block chain address and the amount of coins into the external server 200 in order to purchase power. When the first user inputs information on his block chain address and the amount of coins into the external server 200, the external server 200 generates first information on the power purchase of the first user to the power management server. It can be sent to 300. In this case, the communication unit 330 of the power management server 300 may receive first information on the power purchase of the first user from the external server 200.

On the other hand, the external server 200 interlocks with generating the first information to at least one node constituting the block chain network 400, the amount input by the user from the block chain address of the first user to the block chain address of the server. You can send information (or transaction) that you transfer as many coins as you like. In this case, a plurality of nodes constituting the blockchain network 400 may record the received information (or transactions) as blocks based on a consensus algorithm.

Meanwhile, according to some embodiments of the present disclosure, the first information may include information encrypted with a private key of the external server 200 based on an asymmetric key encryption algorithm. Here, when the first information includes information encrypted with the private key of the external server 200, the processor 310 uses the public key of the external server 200 to store the encrypted information based on an asymmetric key encryption algorithm. It can be decrypted. In addition, when the processor 310 recognizes that the decoded data matches the first information, the processor 310 may recognize that the first information is information transmitted from the external server 200. That is, the processor 310 may decrypt the encrypted information by using the public key of the external server to confirm whether the external server 200 transmits the first information.

The asymmetric key encryption algorithm performed by the external server 200 is: RSA (Rivest, Shamir and Adleman) algorithm, Diffie-Hellman key exchange algorithm, Rabin cryptosystem algorithm, Elgamal encryption ( ElGamal) algorithm, DSA (Digital Signature Algorithm), and elliptic curve cryptography (Elliptic curve cryptography) algorithm may be included.

Meanwhile, the coin change recognition unit 312 of the processor 310 may recognize power amount information on the first amount of power to be supplied to the first user based on the first information about power purchase.

Specifically, the coin change recognition unit 312 may recognize a change amount of coins stored in the virtual wallet of the first user based on the first information. When the coin change recognition unit 312 recognizes that the amount of coins of the first user has changed, it may recognize power amount information on the first amount of power to be supplied to the first user based on the changed amount of coins. In addition, the coin change recognition unit 312 may transmit power amount information about the first amount of power to the power supply unit 340. The power supply unit 340 may determine to supply power to a power supply associated with the first user as the amount of power information is received from the coin change recognition unit 312.

Meanwhile, according to some embodiments of the present disclosure, before determining to supply power to the power supply associated with the first user, the processor 210 uses the first information to use the first information to be stored in the first virtual wallet. You can verify the validity of information about the amount of coins.

Specifically, the account management unit 311 of the processor 310 may update second information on the amount of the first coin currently being stored in the first virtual wallet by using the first information (S120).

As an example, the account management unit 311 stores information indicating that the first user's coin has decreased by a second amount while the first coin is stored in the first virtual wallet, and the coin change recognition unit 312 Can be received from In this case, the account management unit 311 may update the second information to indicate that the third amount subtracted from the first amount by the second amount is the amount of the first coin currently being stored in the first virtual wallet.

As another example, the account management unit 311 receives information from the external server 200 indicating that the first user's coin has increased by a second amount while the first coin is being stored in the first virtual wallet. You can receive it. In this case, the account management unit 311 may update the second information to indicate that the third amount increased by the second amount from the first amount is the amount of the first coin currently being stored in the first virtual wallet.

Meanwhile, according to some embodiments of the present disclosure, the account management unit 311 of the power management server 300 determines the amount of the first coin stored in the server wallet based on the amount of change in the first coin in the recognized first virtual wallet. You can also update it.

Specifically, when receiving a power purchase request from the first user, the account management unit 311 may move at least one first coin from the first virtual wallet of the first user to the server wallet of the power management server 300. have. However, it is not limited thereto.

On the other hand, the account management unit 311 is linked to the movement of at least one first coin from the first virtual wallet to the server wallet to at least one node constituting the blockchain network 400 from the block chain address of the first user. Information (or transaction) indicating that the amount of coins entered by the user is transferred can be transmitted to the server's blockchain address. In this case, a plurality of nodes constituting the blockchain network 400 may record the received information (or transactions) as blocks based on a consensus algorithm.

According to some embodiments of the present disclosure, the processor 310 may receive a public key related to the private key of the external server 200 from the external server 200 through the communication unit 330. In addition, the processor 310 may decrypt the first information using the public key received through the communication unit 330. And, when the processor 310 compares the decrypted data with the plain text of the first information and recognizes that they match, the account management unit 311 uses the first information to determine the amount of the first coin currently being stored in the first virtual wallet. The second information for may be updated.

As described above, when the first information includes information encrypted with the private key of the external server 200 based on the asymmetric key encryption algorithm, the first information will be decrypted only with the public key of the external server 200. I can. When the first information includes information encrypted with the private key of the external server 200, the processor 310 decrypts the encrypted information based on an asymmetric key encryption algorithm using the public key of the external server 200. I can. In addition, when the processor 310 recognizes that the decoded data matches the first information, the processor 310 may recognize that the first information is information transmitted from the external server 200. Meanwhile, if the decoded data and the first information do not match, the processor 310 may ignore the received information.

According to some embodiments of the present disclosure, the account management unit 311 may recognize the remaining amount of first coins currently stored in the first virtual wallet of the first user. In addition, the account management unit 311 may control the communication unit 330 to transmit a message requesting charging of the first coin to the first user terminal 100 when the remaining amount of the first coin is less than the threshold value. Hereinafter, a description of the operation of requesting charging of the first coin will be described in detail later with reference to FIG. 5.

The account management unit 311 may determine whether to roll back the updated second information based on whether the updated second information is valid in step S120 (S130). Here, the rollback may mean returning the update of the second information on the amount of change of the first coin stored in the first virtual wallet. A detailed description of a method of recognizing whether the second information is valid will be described later in detail with reference to FIG. 3.

Similarly, when the amount of coins stored in the server wallet stored in the storage unit 320 is increased, the account management unit 311 may compare the amount of coins stored in the server wallet managed by the blockchain network 400. In addition, when the account management unit 311 recognizes that the compared amount of coins is the same, it may determine that the increased amount of coins is maintained in the server wallet. In addition, when it is recognized that the compared amount of coins is not the same, the account management unit 311 may roll back the amount of coins stored in the server wallet stored in the storage unit 320 to the amount of coins before increasing. have.

When the account manager 311 recognizes that the updated second information is invalid in step S120, the updated second information may be rolled back.

Specifically, when updating the second information, the account management unit 311 may store information before being updated in the storage unit 320 for a preset time. In addition, when it is recognized that the updated second information is not valid, the account management unit 311 may delete the updated second information and load the previously updated information stored in the storage unit 320.

Meanwhile, when the account management unit 311 recognizes that the updated second information is valid in step S120, the updated second information may be maintained without rolling back. In this case, the account management unit 311 may delete information before being updated stored in the storage unit 320 after a preset time. Here, the preset time may be longer than the time required to recognize whether the second information is valid. As described above, when information stored in the storage unit 320 before being updated is deleted after a preset time, the storage space of the storage unit 320 can be efficiently used.

On the other hand, when the power supply unit 340 of the power management server 300 recognizes that the updated second information in step S120 is valid, based on the first information received from the external server 200 in step S110 Accordingly, the power amount information on the first amount of power to be supplied to the first user may be recognized (S140).

Specifically, when it is recognized that the updated second information is valid in step S120, the account management unit 311 may maintain the second information. In this case, the coin change recognition unit 312 may recognize that the amount of the first coin currently being stored in the first virtual wallet has changed. When the coin change recognition unit 312 recognizes that the amount of the first coins currently stored in the first virtual wallet has changed, it may recognize the first amount of power to be supplied to the first user based on the changed amount of coins. In addition, the coin change recognition unit 312 may transmit power amount information about the first amount of power to the power supply unit 340. As the power supply unit 340 receives the power amount information, the power supply unit 340 may recognize power amount information on the first amount of power to be supplied to the first user.

More specifically, when the account manager 311 recognizes that the updated second information is valid in step S120, it may maintain the second information. In this case, the coin change recognition unit 312 may recognize whether the amount of the first coin currently being stored in the first virtual wallet has decreased. The coin change recognition unit 312 may recognize the decrease amount of the first coin when it is recognized that the amount of the first coin stored in the first virtual wallet has decreased. The coin change recognition unit 312 may recognize a first amount of power corresponding to a decrease amount of the first coin. In addition, the coin change recognition unit 312 transmits the power amount information on the first power amount to the power supply unit 340, so that the power supply unit 340 can recognize the power amount information on the first amount of power to be supplied to the first user. . That is, the coin change recognition unit 312 may determine the reduction amount of the first coin according to the updated second information as the amount of power purchased by the first user, and recognize the first amount of power corresponding to the decrease amount of the first coin. .

Meanwhile, the coin change recognition unit 312 may use the mapping information stored in the storage unit 320 when recognizing the first amount of power to be supplied to the first user. Here, the mapping information may be information on how much power can be provided when how much coin is used.

Specifically, the coin change recognition unit 312 may search for a first amount of power corresponding to the amount of coins reduced in the first virtual wallet from mapping information stored in the storage unit 320. In addition, the coin change recognition unit 312 may recognize the searched first amount of power as an amount of power to be provided to the first user who is the owner of the first virtual wallet.

Meanwhile, as the power supply unit 340 of the power management server 300 recognizes the power amount information in step S140, it may determine to supply power to a power supply related to the first user based on the power amount information (S150). ). Here, the power supply may mean an electric meter, a circuit breaker, a distribution board, a switchboard, a switchboard, and the like that can receive power from the power management server 300 and/or the power generation device related to the power management server 300.

According to some embodiments of the present disclosure, the power supply unit 340 may recognize an amount of power supplied to a power supply associated with the first user.

Specifically, the power supply unit 340 may include a virtual meter assigned to a power supply associated with the first user. Here, the virtual meter may be a memory for recording the amount of power supplied from the power supply unit 340 to the power supply associated with the first user. When power is supplied to the power supply associated with the first user, the processor 310 may recognize the amount of power recorded in the virtual meter allocated to the power supply associated with the first user.

According to some embodiments of the present disclosure, when the amount of power supplied to the power supply associated with the first user is recorded in the memory, the processor 310 may separately issue a transaction and write the communication unit 330 to the blockchain network 400. Can be controlled.

In this case, since the amount of power supplied to the power supply related to the first user is recorded in at least one node in the blockchain network 400, it may be stored in a state in which forgery and tampering by a third party can be prevented. have.

Meanwhile, when the amount of power supplied to the power supply related to the first user exceeds a preset value, the processor 310 recognizes whether a second coin different from the first coin exists in the first virtual wallet of the first user. can do.

Here, the second coin may be a coin to which a tag is added to the first coin. In addition, the tag may be an identifier indicating that the coin is issued by selling eco-friendly energy.

When the second coin exists in the first virtual wallet, additional costs for the use of power may not be incurred even when the amount of power used by the power supply device associated with the first user by the first user exceeds a preset value. Hereinafter, a detailed description of the second coin will be described later in FIG. 4.

Meanwhile, the second coin may be a non-stable coin. Here, the non-stable coin may be a coin whose value changes according to the amount of electricity produced.

Specifically, eco-friendly energy produced by at least one individual power producer may not be constant every year. In addition, the power management server 300 may determine the value of the second coin based on the production amount of eco-friendly energy.

For example, in the year (or month) when the production of eco-friendly energy is low, the value of the second coin may increase. For another example, in the year (or month) when the production of eco-friendly energy is high, the value of the second coin may decrease. However, it is not limited thereto.

According to some embodiments of the present disclosure, the processor 310 may recognize a value obtained by subtracting the third amount of power supplied to the power supply associated with the first user through the power supply unit 340 from the first amount of power. And, when the value obtained by subtracting the third power amount from the first power amount is less than the threshold value, the processor 310 transmits a message to the first user terminal 100 to confirm whether the first coin stored in the first virtual wallet is additionally used. The communication unit 330 can be controlled so as to be performed.

That is, the processor 310 may transmit a message to the first user terminal 100 through the communication unit 330 so that power supplied to the first user is not cut off. Hereinafter, an operation of transmitting a message confirming whether the first coin is additionally used will be described in detail later with reference to FIG. 6.

On the other hand, when the power supply unit 340 recognizes that the power equivalent to the first amount of power is supplied to the power supply associated with the first user based on the power amount information, the power supply to the power supply related to the first user terminal 100 is supplied. You can decide to be blocked. That is, the power supply unit 340 recognizes that power supply to the power supply associated with the first user has been completed and determines not to supply power any more, thereby preventing the user from incurring unexpected additional costs.

3 is a flowchart illustrating an example of a method of determining whether the updated second information is valid by the power management server according to some embodiments of the present disclosure.

First, in step S120 of FIG. 2, the account management unit 311 of the power management server 300 may update second information on the amount of the first coin currently being stored in the first virtual wallet of the first user. have.

Meanwhile, referring to FIG. 3, the processor 310 blocks a signal for requesting third information on the amount of coins stored in the block chain address of the first user in order to check whether the updated second information is valid. It is possible to control the communication unit 330 to transmit to the chain network 400 (S131). Here, the third information may be information on the amount of current coins stored in the block chain address of the first user recorded in at least one node in the block chain network 400.

Since the third information is recorded in at least one node in the blockchain network 400, it may be stored in a state in which forgery and tampering by a malicious third party can be prevented.

At least one node constituting the blockchain network 400 may search for third information based on a signal for requesting third information received from the power management server 300 (S132).

Specifically, the block chain network 400 may store transfer details of coins stored in the block chain addresses of not only the first user but also all users. In this case, the signal for requesting third information received from the power management server 300 may include information on the block chain address of the first user. In addition, the blockchain network 400 may search only the transfer details related to the block chain address of the first user among all the coins transfer details of the user.

The blockchain network 400 may calculate third information, which is information on the amount of the final coin recorded in the block chain address of the first user based on the searched transfer history.

On the other hand, in the case of the operation of searching for information within the blockchain network 400, because the state value stored in the DB (Data Base) can be inquired without changing the data of the blockchain, the query information for such search is synchronized to the blockchain. There is no need to do it. Therefore, the nodes of the blockchain network 400 can check their DB for the query and immediately respond to the query regardless of the block synchronization timing. As described above, the processing of the search query in the blockchain network 400 is because the response to the query is performed using the internal DB of the node that received the query, and because the same result can be obtained no matter which node is connected. , Query response speed may be fast.

The blockchain network 400 may transmit the third information to the power management server 300 (S133).

Specifically, the power management server 300 may transmit the public key of the power management server 300 together when transmitting a signal for requesting third information in step S131. In addition, at least one node of the blockchain network 400 may encrypt the third information using the received public key based on an asymmetric key encryption algorithm.

As described above, when the third information is information encrypted with the public key of the power management server 300 based on an asymmetric key encryption algorithm, the third information may be decrypted only with the private key of the power management server 300. In addition, since the private key of the power management server 300 may only have the power management server 300, a malicious third user is transmitted from the blockchain network 400 to the power management server 300. You can prevent information from being hacked and modified.

Meanwhile, the account management unit 311 of the power management server 300 may compare the updated second information and the third information received from the blockchain network 400 to determine whether the updated second information is valid ( S134).

Specifically, when the updated second information and the third information match, the account management unit 311 may recognize that the updated second information is valid.

Meanwhile, when the updated second information and the third information do not match, the account management unit 311 may recognize that the updated second information is not valid. In this case, the account management unit 311 may roll back the updated second information to a state before being updated.

Accordingly, information on the amount of the first coin currently stored in the first virtual wallet of the first user stored in the power management server 300 may exist in a state in which integrity is guaranteed.

4 is a flowchart illustrating an example of a method of determining, by a power management server, that a second coin is used, according to some embodiments of the present disclosure.

Referring to FIG. 4, the coin change recognition unit 312 of the power management server 300 may recognize the amount of power supplied to the power supply associated with the first user through the power supply unit 340.

Specifically, the power supply unit 340 may include a virtual electricity meter allocated to a power supply associated with the first user. In addition, the power supply unit 340 may recognize the amount of power supplied to the power supply associated with the first user through the provided virtual meter.

On the other hand, when the amount of power supplied recognized through the power supply unit 340 exceeds a preset value (S210, Yes), the account management unit 311 provides a second, different from the first coin in the first virtual wallet of the first user. It is possible to recognize whether a coin exists (S220). Here, the preset value may be a value in which a section in which additional cost according to the use of power starts to be generated is set. For example, it may be a value for a point in time when the progressive tax is applied. However, the rate plan that incurs additional costs is not limited to progressive tax, but the Real Time Pricing, Two-Part rate schedule, Critical Peak Pricing, and Time Of Use. And the like. However, in the present disclosure, for convenience of explanation, it is assumed that the fee related to the fee incurred in additional costs is progressive, and will be described below.

In the present disclosure, the amount of power produced by the power generation device managed by the power management server 300 may be insufficient to supply all of a plurality of users. In this case, the first user may generate electricity in a power generation device owned by the first user, and may supply the generated electricity to the power management server 300. In addition, the power management server 300 may provide a second coin to which a tag is added to the first coin as compensation for power supplied by the first user. That is, the tag may be an identifier indicating that the coin is issued by selling eco-friendly energy.

Specifically, when the second coin exists in the first virtual wallet, additional costs for the use of power will not be incurred even if the amount of power used by the power supply associated with the first user by the first user exceeds a preset value. I can. That is, the second coin may be a coin that is not affected by the progressive tax.

Specifically, for example, when the amount of power used by the first user is less than a preset value, the coin change recognition unit 312 controls the power supply unit 340 to supply 10 kwh of power when it recognizes that the first coin has decreased by one. can do. And, when the amount of power used by the first user exceeds a preset value, the coin change recognition unit 312 may control the power supply unit 340 to supply 5 kwh of power when it recognizes that the first coin has decreased by one. have. On the other hand, regardless of the amount of power used by the first user, the coin change recognition unit 312 may control the power supply unit 340 to supply 10 kwh of power when it recognizes that the second coin is reduced by one. However, the amount of power supplied according to the change amount of the first coin and the second coin is not limited to the above-described example.

Therefore, if the amount of power used by the first user is less than a preset value, the first coin purchased from the external server 200 is used, and if the amount of power used exceeds the preset value, the second coin is used to purchase power. You can reduce the cost consumed by the product.

Meanwhile, the first user can purchase the second coin from another user through the coin exchange. In addition, the first user may sell the second coin to other users through the coin exchange. However, the present invention is not limited thereto, and the first user may purchase or sell the second coin in various ways.

When the second coin exists in the first virtual wallet of the first user (S220, Yes), the account management unit 311 of the power management server 300 is instead of the first coin for the second amount of power exceeding a preset value. It may be determined that the second coin is used (S230).

Specifically, the account management unit 311 exceeds a preset value (S210, Yes) and the amount of power supplied through the power supply unit 340 to the power supply associated with the first user, and is added to the first virtual wallet of the first user. 2 It can be recognized that the coin exists (S220, Yes). In this case, the account management unit 311 may determine that the first coin equal to the second amount corresponding to the second amount of power exceeding a preset value is maintained in the first virtual wallet. In addition, the account management unit 311 may determine that the second coin equal to the third amount corresponding to the second amount of power is reduced in the first virtual wallet in conjunction with determining that the first coin is maintained in the first virtual wallet. .

That is, the account management unit 311 consumes the second coin in response to the second amount of power exceeding a preset value, thereby preventing the first user's assets from being wasted unnecessarily.

Meanwhile, according to some embodiments of the present disclosure, the account management unit 311 of the power management server 300 determines the amount of the second coin stored in the server wallet based on the amount of the second coin change in the recognized first virtual wallet. You can also update it.

Specifically, when it is determined that the second coin is reduced in the first virtual wallet, the account management unit 311 may move at least one second coin from the first virtual wallet to the server wallet of the power management server 300. However, it is not limited thereto.

On the other hand, the account management unit 311 is linked to the movement of at least one second coin from the first virtual wallet to the server wallet, to at least one node constituting the block chain network 400 from the block chain address of the first user. Information (or transaction) indicating that the amount of coins entered by the user is transferred can be transmitted to the server's blockchain address. In this case, a plurality of nodes constituting the blockchain network 400 may record the received information (or transactions) as blocks based on a consensus algorithm.

In the present disclosure, the first user may set the second coin not to be used even when the power supplied to the power supply associated with the first user through the first user terminal 100 exceeds a preset value. That is, the first user can store the second coin in preparation for a period in which power consumption is expected to be large by using the first coin even when the value at the time when the progressive tax is applied exceeds a preset value.

On the other hand, the account management unit 311 is determined to use the second coin instead of the first coin for the second amount of power exceeding the preset value in step (S230), the first coin as much as the second amount in the first virtual wallet. It is possible to generate fourth information indicating that this has not been used, and that the third amount of the second coin has been used. In addition, the account management unit 311 controls the communication unit 330 to transmit the fourth information to a plurality of nodes constituting the block chain network 400, so that a consensus algorithm at a plurality of nodes constituting the block chain network 400 May cause the fourth information to be recorded in blocks.

When the fourth information is recorded in the blockchain network 400, it is virtually impossible to forge or falsify. Accordingly, it is possible to prevent a malicious third party from hacking and modifying the fourth information, and the recorded fourth information may be stored in a state in which integrity can be guaranteed.

On the other hand, when the account management unit 311 recognizes that the amount of power supplied to the power supply related to the first user through the power supply unit 340 does not exceed a preset value (S210, No), the first amount of power is You can decide to use the coin.

The account management unit states that the amount of power supplied to the power supply related to the first user through the power supply unit 340 exceeds a preset value (S210, Yes), and that the second coin does not exist in the first virtual wallet of the first user. When it is recognized (S220, No), it may be determined that the first coin is used for the second amount of power exceeding a preset value (S240).

Meanwhile, in the present disclosure, when the account management unit 311 recognizes that the amount of power supplied to the power supply related to the first user through the power supply unit 340 does not exceed a preset value (S210, No), the first user If there is only a second coin in the first virtual wallet of, the second coin may be used.

According to some embodiments of the present disclosure, in addition to the first coin and the second coin, a third coin may be stored in the first virtual wallet of the first user. Here, the third coin may be a coin that can be used in a section in which further additional costs begin to occur beyond a section in which additional costs according to the use of power begin to occur.

For example, assuming that the section using the first coin is the first section, the section using the first progressive tax is applied, and the section using the second coin is applied with the second section and the second progressive tax, so that the third coin is used. The section may be a third section. However, the section in which the third coin is used is not limited thereto. In addition, the coins stored in the first virtual wallet of the first user are not limited to the first coin, the second coin, and the third coin.

Meanwhile, the third coin may be a coin to which a tag is added to the first coin or the second coin. In addition, the tag may be an identifier indicating that the coin is issued by selling eco-friendly energy.

Meanwhile, the third coin may be a non-stable coin. In addition, the non-stable coin may be a coin whose value changes according to the amount of electricity produced. According to some embodiments of the present disclosure, a tag that can indicate that the coin is issued by selling eco-friendly energy is It may include a first tag according to sales and a second tag according to sales of renewable energy.

Here, the non-renewable energy may be energy collected from non-renewable resources. For example, non-renewable energy may include at least one of biomass, waste, marine energy, or landfill gas. In addition, non-renewable energy is not renewable energy, but may be eco-friendly energy compared to existing coal or petroleum energy. In addition, coins issued by selling non-renewable energy may be attached with a first tag. However, it is not limited thereto.

Meanwhile, the renewable energy may be energy collected from renewable resources. For example, the renewable energy may include at least one of solar heat, solar power, wind power, or geothermal heat. That is, the renewable energy may be energy in which an amount used by a natural process is regenerated even after being used once. In addition, a second tag may be added to coins issued by selling renewable energy. However, it is not limited thereto.

5 is a flowchart illustrating an example of a method of transmitting a message requesting a coin charge to a first user terminal by the power management server according to some embodiments of the present disclosure.

Referring to FIG. 5, the account management unit 311 of the power management server 300 may recognize the remaining amount of the first coins currently being stored in the first virtual wallet of the first user.

And, when the remaining amount of the first coin currently being stored is less than the threshold value (S310, Yes), the account management unit 311 transmits a message requesting the charging of the first coin to the first user terminal 100 so that the communication unit 330 It can control (S320).

Here, the threshold value may be generated by a request received from the first user terminal 100 through the first user. As another example, information on the threshold may be pre-stored in the storage unit 320.

Meanwhile, when the remaining amount of the first coin currently being stored is greater than or equal to the threshold value (S310, No), the account management unit 311 may not transmit a message requesting to charge the first coin to the first user terminal 100.

In the present disclosure, the account management unit 311 may control the communication unit 330 to transmit a message requesting charging of the first coin to the first user terminal 100 at predetermined intervals.

As an example, the preset interval may be an interval generated by the coin change recognition unit 312 analyzing a pattern for the amount of power consumed by the first user.

As another example, the preset interval may be an interval generated based on time intervals such as week, month, and year.

On the other hand, the account management unit 311 controls the communication unit 330 to transmit a message requesting the charging of the first coin to the first user terminal 100, thereby preventing additional costs for the first user to use power. can do.

Similarly, the account management unit 311 may recognize the remaining amount of the second coin currently being stored in the first virtual wallet of the first user. In addition, the account management unit 311 may control the communication unit 330 to transmit a message requesting charging of the second coin to the first user terminal 100 when the remaining amount of the second coin currently being stored is less than the threshold value. .

6 is a flowchart illustrating an example of a method of transmitting a message confirming whether a first coin is additionally used by a power management server according to some embodiments of the present disclosure.

6, the coin change recognition unit 312 is based on the power amount information from the power supply unit 340 to the power supply associated with the first user from the amount of power determined to be supplied to the power supply associated with the first user. It is possible to recognize a value obtained by subtracting the third amount of power that has been supplied.

That is, the coin change recognition unit 312 may recognize a value obtained by subtracting the first amount of power, which is the amount of power to be supplied through the power supply unit 340, and the third amount of power, which is the amount of power that has been supplied.

In addition, when the value obtained by subtracting the third amount of power from the first amount of power is less than the threshold value (S410, Yes), the coin change recognition unit 312 provides a message confirming whether to use the first coin stored in the first virtual wallet. 1 It is possible to control the communication unit 330 to transmit to the user terminal 100 (S420).

The power management server 300 may receive a first signal including a response to a message confirming whether to use the first coin from the first user terminal 100 through the communication unit 330. In this case, the account management unit 311 may allow the first coin to be additionally used in the first virtual wallet of the first user.

Specifically, the account management unit 311 generates fifth information on the amount of change in the coin of the first user based on the first signal received from the first user terminal 100, and uses the fifth information to generate the fifth information. The sixth information on the amount of the first coin currently being stored in the user's first virtual wallet may be updated. In addition, the account management unit 311 may verify the validity of the updated sixth information through the above-described methods.

The communication unit 330 of the power management server 300 may not be able to receive a signal including a response to a message confirming whether to use an additional first coin from the first user terminal 100 for a preset time. In this case, the account management unit 311 may control the communication unit 330 to retransmit a message confirming whether the first coin is additionally used to the first user terminal 100. Here, information on a preset time may be pre-stored in the storage unit 320.

Accordingly, the coin change recognition unit 312 may induce the power supply to not be cut off when the first user uses power.

On the other hand, when the account management unit 311 recognizes that the coins stored in the first virtual wallet of the first user are exhausted without receiving the first signal from the first user terminal 100, the account management unit 311 311 may control the power supply unit 340 so that power is not supplied to the power supply associated with the first user.

When the value obtained by subtracting the third amount of power from the first amount of power is equal to or greater than the threshold value (S420, No), the coin change recognition unit 312 may not transmit a message confirming whether the first coin is additionally used.

The external server 200 may transmit first information, which is the power purchase information of the first user, to the power management server 300 based on the power purchase request received from the first user (S520).

Specifically, when the external server 200 receives information on the block chain address of the first user and the amount of coins from the first user terminal 100, the external server 200 generates first information on the power purchase of the first user. It can be transmitted to the power management server 300.

On the other hand, the external server 200 interlocks with generating the first information to at least one node constituting the block chain network 400, the amount input by the user from the block chain address of the first user to the block chain address of the server. You can send information (or transaction) that you transfer as many coins as you like. In this case, a plurality of nodes constituting the blockchain network 400 may record the received information (or transactions) as blocks based on a consensus algorithm.

In addition, the power management server 300, which has received the first information from the external server 200, sends a signal for requesting third information about the amount of coins stored in the blockchain address by the first user to the blockchain network 400. It may be transmitted to at least one node constituting the (S530).

Specifically, the power management server 300 sends a signal for requesting third information on the amount of coins stored in the block chain address of the first user in order to check whether the information on the coin change amount is valid or not to the blockchain network ( The communication unit 330 may be controlled to transmit to 400).

Meanwhile, at least one node constituting the blockchain network 400 may transmit third information on the amount of coins based on the signal received in step S530 (S540).

Specifically, the blockchain network 400 searches only the transfer details related to the block chain address of the first user, and based on the searched transfer details, the first user, which is information on the amount of the final coin recorded in the block chain address of the first user. 3 You can search for information. In addition, the searched third information may be transmitted to the power management server 300.

In addition, the account management unit 311 of the power management server 300 may verify whether the coin change amount is valid (S550).

Specifically, the account management unit 311 may determine whether the second information updated in the first virtual wallet of the first user and the third information received from at least one node constituting the blockchain network 400 match. I can. In addition, the account management unit 311 may recognize that the coin change amount is effective when the updated second information and the third information match.

Finally, when it is recognized that the coin change amount is valid, the account management unit 311 may control the power supply unit 340 to supply power to the power supply associated with the first user (S560).
