The invention discloses a renewable distributed energy unified price bidirectional auction transaction method based on a super account book, and the method comprises the following steps that a distributed renewable energy green certificate needs to be audited by a government supervision node, and a platform node creates an intelligent contract and initiates bidirectional auction; prices are unified, and green certificate bidirectional transaction is carried out while electric quantity transaction is carried out. An independent channel is created based on a super account book technology, and related trader nodes are isolated for independent communication. the intelligent contract is deployed in the local database of each node, and the transaction electric quantity and the corresponding green certificate are encrypted and uploaded. And after the intelligent contract triggers the transaction, the settlement data includes green certificate examination, and after verification is performed at each transaction-related node, the transaction pays electric charge and purchases a corresponding green certificate. The invention is used for distributed energy spot transaction, and rapid, safe and efficient transaction of renewable energy sources is achieved.
