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.
