Distributed power supply settlement clearing method and system

Abstract

The invention discloses a distributed power supply settlement clearing method and system, and the method comprises the steps that the power supply transaction settlement is carried out on a block chain network, a clearing contract stored on a block chain is automatically triggered, and the clearing between distributed power supply settlement clearing objects is completed; if the objects of the two groups of clearing transactions comprise the same object, the clearing contract is executed in a serial calculation mode, and otherwise parallel calculation is adopted; the block chain network takes a distributed power supply settlement object as a node, and a node consensus adopts a group architecture; and finally, settlement and clearing results are stored on the chain, and perfect man-machine interaction functions of querying historical transactions, displaying user information on the chain and the like can be provided through a client of the block chain network. According to the method, the block chain network with low operation and maintenance complexity and high node consensus speed is constructed, the contract execution efficiency is improved by adopting a parallel computing mode based on the dependency relationship, the fairness and reliability of settlement and clearing are ensured, and the settlement and clearing cost is reduced.

Description

technical field [0001] The invention relates to a method and system for settlement and clearing of distributed power sources. Background technique [0002] There are many types and quantities of market entities involved in distributed energy transactions, and the transaction frequency is high and the transactions are relatively scattered. In the traditional centralized transaction mode, transaction data is stored in the transaction center, which is easy to cause data loss and poor security; high frequency, decentralized The transaction will occupy a lot of system resources, the execution efficiency of the centralized system is low, and the operation and maintenance cost and operation cost are high; this centralized transaction mode is no longer applicable to the current energy transaction. At present, the blockchain smart contract technology is often used to realize the automatic settlement of distributed transactions by using the blockchain smart contract to provide a fair ...

[0002] There are many types and quantities of market entities involved in distributed energy transactions, and the transaction frequency is high and the transactions are relatively scattered. In the traditional centralized transaction mode, transaction data is stored in the transaction center, which is easy to cause data loss and poor security; high frequency, decentralized The transaction will occupy a large amount of system resources, the execution efficiency of the centralized system is low, and the operation and maintenance cost and operating cost are high; this centralized transaction mode is no longer applicable to the current energy transaction

At present, the blockchain smart contract technology is often used to realize the automatic settlement of distributed transactions by using the blockchain smart contract to provide a fair trading environment for all market players. However, the relationship between nodes in the existing trading network is unequal, and most of the data is still It needs to be transmitted to the trading center for calculation, the node operation and maintenance complexity is high, and the smart contract execution efficiency is low
