Description

Credit mechanism method for electric power transaction
Technical Field
The invention relates to the technical field of block chains, in particular to a credit mechanism method facing to electric power transaction.
Background
A large number of distributed electric energy producers and consumers enter the electric power system, and the surge of a large number of producers and consumers with independent decision-making capability puts new demands on data disclosure transparency, transaction safety and fairness in the electric power system. Therefore, establishing a safe, efficient and transparent transaction mechanism will become the key of the reform of the Chinese electric power system.
The credit management mechanism is an important link in the design of a block chain-based electric power trading platform and a trading model. How to accurately evaluate the credit level of each party of the electric power transaction and effectively stimulate each party to improve the active performance of the contract is the key of the design of a credit management mechanism. At present, the credit management of the power market is not perfect enough, and the credit rating has the problems of weak performance awareness of market members, oligopolism, lack of a reasonable mechanism and the like. How to establish a credit incentive mechanism based on transaction data in a transaction system to promote users to actively reduce default behaviors and maintain own credit is a problem worthy of deep research.

Mtotal＝Pcontact×Ndeal+M
wherein N iscontactTransaction power amount for intelligent contract, NdealIs the electricity amount of the actual two parties transaction.
The invention achieves the following technical effects:
the block chain is used as a technically supported transaction model, transaction data can not be falsified when being stored in the block chain, and the privacy of the transaction can be guaranteed on the premise that the transaction is public and transparent. The blockchain can automatically generate intelligent contract contents without interference of other factors. The node credit level is improved, and the key of the healthy operation of the distributed power trading platform taking credit as a core is provided. Therefore, the node default behaviors are reduced, and the performance and the reasonability of the node in the real-time electric power market transaction are improved.
