The invention relates to an extensible
distributed power transaction method in a multi-
microgrid environment. The method comprises the following steps of S1, constructing a block
chain network; S2, examining the permission allowing a user to enter a transaction market; S3, allocating the public and private keys and the wallet addresses; S4, before each transaction gap, enabling a
consumer to submit the quotation information, and a producer and a salesman to submit the bidding information; encrypting all quotation information and bidding information by the public and private keys; S5, completing the bidding matching according to a bidirectional auction mechanism; S6, judging whether a transaction rule is met or not, if yes, executing S7, and if not, returning to S4; S7, carrying out
power transmission, and enabling an intelligent electric meter to monitor the
electric energy transmission of a node in real time; S8, completing the market clearing; and S9, enabling each
microgrid operatorto compete for an accounting right according to a
workload proof mechanism, and enabling a winner to be an accountant to make a block and embed the block into a block
chain network. According to theinvention, the distributed energy transaction
system can realize the higher energy transaction efficiency and the stronger stability.
