Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The method aims to guarantee the reliability of a whole chain of autonomous negotiation, interaction, transaction, settlement and the like between a user and a demand response system under the condition that massive demand response users participate, ensure the safety and reliability of the implementation of demand response services, ensure the safe and efficient operation of a power grid, and effectively avoid false response and malicious response. The invention mainly solves the functions of identity authentication of a demand response main body, contract storage, intelligent contracts, response data audit and the like through a block chain technology, and realizes the flow and the data reliability of the demand response business.
Example 1:
fig. 1 shows a schematic diagram of a block chain-based high-confidence demand response system provided by the present invention, which includes: a plurality of nodes; each node is connected to form a block chain;
each demand response user participating in electric power and data transaction is connected with the node;
the node is configured to: the method includes storing identity information of connected demand response customers, demand response contracts, and data for demand response electricity transactions, and executing the demand response contracts when trigger conditions of the demand response contracts are satisfied.
With the development of energy internet and electric power market, the automatic demand response ADR which does not need manual intervention and spontaneously adjusts load is the main development trend of energy management and control of an energy local area network system, and the fitting degree of the ADR and the block chain concept is mainly embodied in the following 3 aspects:
(1) and (3) embodying the decentralized idea. The block chain technology supports point-to-point direct transaction of massive users, information is public and transparent, and a credible distributed system without a center is formed by relying on distributed technologies of accounting, transmission, storage and the like. The peer-to-peer and decentralized characteristics of the block chain can provide important technical support for response main bodies to make optimal decisions autonomously and realize efficient energy utilization.
(2) Emphasizing the development of marketization. The block chain technology as a new generation information technology may radically change the behavior mode of market trading, and the characteristics of disclosure and decentralization are favorable for forming a transparent market pattern. The advantage of the block chain in the aspect of market trading can promote the trading and interaction of the energy system which is participated in from multiple directions at the demand side, and the improvement of the autonomous supply and demand balance level of the ADR project and the exertion of the market mechanism function are facilitated by combining the transparent symmetry and credibility of the information.
(3) The intellectualization and the reduction are emphasized. The intelligent contract is decentralized and trusted shared program codes deployed on a blockchain, and based on the decentralized and trusted program codes, various social system functions can be automatically executed by being packaged on the decentralized and trusted blockchain. Decisions, transaction behaviors and the like in the ADR project have the tendency of intelligent development, and the intelligent contract based on the block chain can regulate the electric power transaction behaviors of the energy storage system, so that fair and efficient execution of transactions and benefit distribution is automatically guaranteed.
Block chain based demand response service architecture
According to the difference of development objects of the block chains, the block chains can be divided into three types: public, private, and federation chains. The public chain is opened to all people, and nodes can be added randomly; private chains are open only to individual entities, such as within a company; a federation chain may be open to a particular organization.
The alliance chain is controlled by a plurality of centers, the system is subjected to distributed accounting by a plurality of authoritative organizations, and the nodes work cooperatively according to a consensus mechanism. This is a partially decentralized blockchain that allows users to review and transact, but requires inter-federation decisions to validate transactions. The most remarkable characteristic of the alliance chain is that each node corresponds to an entity organization, any entity organization node wants to join the alliance connection and needs to obtain the permission of the alliance, and the organizations jointly maintain the stable development of the system.
The demand response service has strict requirements on problems of data privacy, safety, supervision and the like because the demand response service relates to power grid and user power operation data, and therefore a alliance chain mode is proposed to carry out verification of the test point project. As shown in fig. 2, in the demand response architecture based on the block chain, demand response implementation subjects such as a power grid company, an electricity selling company, a load aggregator, an integrated energy service company, and a part of large users may join the alliance chain, and an electric power scientific research institution may join the alliance chain as a third-party consulting institution and a government as a regulatory institution. And other users participating in the response access the load aggregator or are hosted by the integrated energy service company and then join the load aggregator. The accounting node and the supervision node in fig. 2 are all nodes on the block chain, and are the same in nature; when the user of the node is a third-party consulting organization and a demand response implementation main body, the node is called a billing node; when the user of a node is a supervising authority, the node is referred to as a supervising node.
Block chain-based demand response terminal
According to the main category participating in the demand response, the demand architecture of the blockchain data network and the terminal is designed, and the overall network structure of the system is schematically shown in fig. 3. The blockchain link point server and the distributed transaction unit in fig. 3 are both nodes on the blockchain; when the node is connected with the gateway of energy metering, the node can be called a distributed transaction unit, and if the node is not connected with the gateway of energy metering, the node is called a node server.
And each energy metering gateway is accessed to the block chain network through a distributed transaction unit.
Each distributed transaction unit is physically connected with the adjacent transaction units, each distributed transaction unit must be connected with at least one node on the chain, and the distributed transaction units and the node servers corresponding to all the demand response implementation bodies form a block chain storage network structure.
The application server provides data support for the final service presentation through the block chain service provided by the node server.
And the external system switch is connected with the application server and is respectively connected with the monitoring client and the operation client.
A demand response implementation user monitors a demand response system through a monitoring client;
and the demand response implementation user carries out the operation of the demand response service through the operation client.
The system switch is also connected with a mobile phone transmission network, and a user can access the block chain through intelligent equipment such as a mobile phone.
Block chain main side chain application design
The high-reliability demand response system based on the block chain is established as an alliance chain which participates in multiple parties and shares resources and data, and users, power grid enterprises, load aggregators, electricity selling companies, comprehensive energy companies and governments can fully realize value exchange, efficiency improvement and development promotion by means of a platform. FIG. 4 shows a block chain main side chain application design. The master nodes in fig. 4 represent important nodes on the main chain, and are essentially the same as the other nodes.
(1) The main chain is used as a sharing platform of all participants, and the main chain is used for proving that electric power and data transaction is carried out among the members of the alliance;
(2) the participator selects to build or participate in Distributed Application (DAPP) of the existing business according to the business and the client of the participator, and can select to independently issue internal certificates to meet different business requirements;

Responding to subject identity authentication
The identity authentication mainly comprises functional modules of member registration, user login, user verification, user query, identity management, access audit, access control and the like. The business flow is schematically shown in figure 5.
The identity management unit cooperates with an authentication node which provides a certificate signature for the member (including the transaction of course) and only the client who obtains a legitimate certificate can submit the transaction or inquire about the transaction. The authentication node is also a node on the blockchain, and is called an authentication node because it is more biased to the application of authentication.
In the electric power trading market system, the management of the user identity has a strict auditing function, and the registration, application and issuance of all users are recorded on a block chain.
Demand response contract deposit certificate
And constructing a demand response contract deposit certificate system based on the block chain. When the contract text (doc/docx/pdf and other format files) confirmed by each party of the demand response service is uploaded to the cloud, a digital fingerprint corresponding to the contract text is generated, the digital fingerprint is stored on the block chain platform, and the relevant parties of the contract use the respective reserved private keys to carry out digital signature.
When the cloud contract is required to be verified, only a digital fingerprint is generated from the contract text stored in the cloud according to the same algorithm and is compared with the digital fingerprint anchored on the block chain, and the verification of the authenticity of the cloud electronic contract text can be completed.
