Renewable energy electric power management method, device and system

The invention discloses a renewable energy power management method, device and system, which are applied to a block chain. The method comprises the following steps: acquiring demand information and supply information; obtaining the matching degree of the demand information and the supply information through a smart contract; when the matching degree is greater than or equal to a preset threshold,obtaining an accounting node; broadcasting the renewable energy power transaction to the accounting node; and when the accounting node is successfully verified through a consensus mechanism, settlingthe renewable energy power transaction. According to the renewable energy electric power management method provided by the invention, a multi-stage asynchronous layered calling mechanism is adopted, and the execution speed of the transaction is improved, so that the high concurrency demand of renewable energy electric power transaction is met. 本申请公开了一种可再生能源电力的管理方法、装置及系统，应用于区块链。所述方法包括获取需求信息与供给信息；通过智能合约获得所述需求信息与所述供给信息的匹配度；当所
