And S2, establishing a peer-to-peer network of the elementary nodes.
And S3, submitting energy requirements such as an energy output plan and an energy purchase plan to the system by the primary node in the energy Internet.
And S4, the high-level nodes in the system receive and process the energy transaction plan, match transaction prices and energy transaction quantity according to the electricity price checking principle, broadcast transaction information such as the matched prices and the like in the primary node network, and write the transaction information into the high-level node block chain.
And S5, the primary node conducts transaction according to the block information in the high-level node block chain, writes the transaction information into the primary node block chain, and forms an energy transaction intelligent contract.
The peer-to-peer network of higher nodes in step S1 has the following specific features:
a peer-to-peer network, i.e., a peer-to-peer computer network, is a distributed application architecture that distributes tasks and workloads among peers (nodes), and is a networking or networking form of the peer-to-peer computing model formed in the application layer. It can be defined as: participants of the network share a portion of the hardware resources (processing power, storage power, network connectivity, printers, etc.) they own, which provide services and content over the network and which can be accessed directly by other peer nodes without going through intermediate entities. Participants in this network are both providers and acquirers of resources, services and content.
The higher node is a computer node used by a supervising authority that transacts and operates the energy internet transaction and participates in a higher node peer-to-peer network in order to participate in supervising the energy transaction.
The network has the main functions of realizing a high-level node block chain, collecting transaction information, performing centralized bidding and matching on transactions, generating a high-level node block, verifying block information and other system primary functions.
The peer-to-peer network of higher nodes in step S2 has the following specific features:
the organization form of the peer-to-peer network of the elementary nodes is the same as that of the peer-to-peer network of the higher nodes in S1.
The primary node is a computer node used by a user who needs to perform energy transaction, including an energy producer and seller, a power generation enterprise, a power grid enterprise, an auxiliary service provider, and other enterprises or individuals who perform energy transaction, and participates in a peer-to-peer network of primary nodes in order to participate in energy transaction.
The network has the main functions of realizing elementary node block chains, collecting transaction information, verifying matching transaction information, generating blocks, verifying block information and other system elementary functions.
The specific information provided by the primary node to the system in step S3 is characterized by:
the information comprises ID of the elementary node, wherein the ID is unique in the energy Internet and is recorded in a supervisor to form a binding mechanism of a transaction main body and the ID, so that real-name transaction of energy transaction is realized; the types of the energy trading plans, such as electric energy trading, heat power trading, gas trading and other different energy trading types; specific energy trading plans are quantifiable unified trading information such as energy purchase amount (sales volume), willingness trading price, energy availability period and the like.
The centralized bidding and matching transaction implementation method in the step S4 is characterized in that:
the high-level node continuously collects primary network transaction intention information in the network through the primary peer-to-peer network, processes backlog transaction information at a certain specific time, and simultaneously receives new round of transaction intention information. The high-level peer-to-peer network divides the calculation information into blocks, utilizes the strong calculation capacity of the high-level peer-to-peer network and the distributed calculation function to finally broadcast the calculation result of the time interval, verifies the final transaction information through other nodes in the high-level peer-to-peer network, creates a high-level node block containing the matched transaction information through a high-level node block chain system after verification, and broadcasts the high-level node block to the full-level peer-to-peer network system.
The elementary node block chain system in step S5 and the method for implementing the intelligent contract are characterized by the following:
when the peer-to-peer network receives the matching transaction information broadcasted in step S4, the peer-to-peer node participating in the transaction automatically sends a transaction request to the peer-to-peer blockchain system from the personal computer, and broadcasts to the whole network and performs authentication through the consensus algorithm of the peer-to-peer blockchain system.
When the verification result is true, creating a block of the transaction and forming an intelligent contract of both parties of the transaction.
When the trigger mechanism of the intelligent contract is false, the intelligent contract does not trigger. When the trigger mechanism of the function contract is true, the system automatically records the transaction information from the electronic wallets of the two parties and records the transaction information into the elementary node block chain to indicate that the transaction is completed.
In order to facilitate the technical solutions further understood by those skilled in the art, the following description is made with reference to examples:
s1, establishing a peer-to-peer network of high nodes. As in fig. 2, a peer-to-peer network is established between higher nodes.
And S2, establishing a peer-to-peer network of the elementary nodes. As shown in fig. 3, a peer-to-peer network is established between the primary nodes. Subsequently, the nodes between the elementary node network and the higher node network want to be interconnected, so as to form an energy internet weak centralized transaction system peer-to-peer network based on the block chain network, as shown in fig. 4.
And S3, submitting energy requirements such as an energy output plan and an energy purchase plan to the system by the primary node in the energy Internet. For example, the energy producer A, B assumes the roles of energy consumer and energy producer, respectively, based on its own load imposed. First, the energy consumer a and the energy producer B send transaction requests to the elementary peer-to-peer network, waiting for the advanced node peer-to-peer network to process the data.
And S4, the high-level nodes in the system receive and process the energy transaction plan, match transaction prices and energy transaction quantity according to the electricity price checking principle, broadcast transaction information such as the matched prices and the like in the primary node network, and write the transaction information into the high-level node block chain. For example, the higher node network receives transaction request information from the energy producers A, B of the first node network, packages the transaction information according to different energy types, and distributes computing tasks in the higher node network. And then, the high-level node network finishes the operation task and submits the high-level node peer-to-peer network for verification, and after the verification is passed, the matching result is recorded into the high-level node block chain. And finally, broadcasting the formed transaction matching information to all primary nodes through an energy internet weak centralized transaction system peer-to-peer network based on a block chain network. For example, the energy consumer a matches the best energy producer C, the latter a combination of other energy best energy producers, according to the price he offers and the amount of energy needed. Meanwhile, the system also approves or rejects certain transaction information which may influence the system safety on the basis of ensuring the safe and stable operation of the system according to the operation key parameters of the energy system, such as active power, reactive power balance, heat balance, gas balance and the like.
And S5, the primary node conducts transaction according to the block information in the high-level node block chain, writes the transaction information into the primary node block chain, and forms an energy transaction intelligent contract. For example, the first-class node packages and encrypts the energy transaction amount paid to the energy producer C by receiving the broadcast information fed back by S4. And sends the public key encryption (including the transaction address) with the energy producer C to C, which decrypts the transaction with his private key. Namely, the energy consumer A and the energy producer C utilize the elementary node blockchain to carry out energy transaction, and the energy transaction information record is broadcasted to the blockchain to form an intelligent contract. When the intelligent contract effective condition is judged to be true, for example, the effective time period of the energy required by A and the energy provided by C is from 12 noon to 3 afternoon of the next day, the transaction is already logged into the elementary node block chain and the intelligent contract is generated, and when the system time does not reach the appointed transaction time, the intelligent contract is not triggered. When the system time reaches the effective time, the intelligent contract is triggered, the transaction information is written into the elementary node block chain, and the elementary node block chain is submitted to the whole network for verification.
