Power transaction method based on multi-chain block chain architecture

Abstract

The invention discloses a power transaction method based on a multi-chain type block chain architecture, and the method comprises the steps: pre-constructing the multi-chain type block chain architecture, enabling a plurality of block chains to be coupled through a plurality of common nodes, and setting a transaction target function and a constraint condition; when a transaction demand is generated, each node carries out a transaction in a manner of signing an intelligent contract according to a preset transaction objective function and a constraint condition, and competes for an accounting right according to an accounting right consensus algorithm based on an integrity value, and the shared node carries out cross-chain processing on information between different block chains in the transaction process. According to the invention, the multi-chain block chain is adopted, and various types of information related to the transaction can be selectively shared and verified in a multi-chain architecture through common node coupling, so that the security is improved; the accounting right is competed through the accounting right consensus algorithm based on the honesty value, the node user can be guided to comply with the intelligent contract, the priority of the honesty node is improved, malicious behaviors are avoided, and the transaction efficiency and quality are improved.

Description

technical field [0001] The invention relates to the field of data security, in particular to a power transaction method based on a multi-chain block chain architecture. Background technique [0002] With the development of distributed energy technology and strong support at the policy level, distributed energy equipment (DER) will be more and more widely used. Traditional electricity consumers are transformed into prosumer consumers with dual attributes of electricity production and consumption. As a relatively independent power grid structure, the microgrid can directly meet the transaction needs of production and consumption users and realize the efficient use of clean energy. The traditional microgrid power trading strategy has the phenomenon of lack of trust between the two parties and opaque information, which makes the transaction data in the microgrid system easy to be tampered with and the transaction efficiency cannot be effectively guaranteed. Therefore, the key ...
