The invention discloses a community energy autonomous method containing distributed power generation based on a block chain technology. The community energy autonomous method specifically comprises the steps of determining a connection relationship among electrical devices in a community and parameters of the electrical devices; constructing a block chain P2P network covering each electrical device in the community, and establishing a consensus mechanism and decentralized trust of block chain driven community distributed power generation automatic transaction and autonomous scheduling; each electrical device or measurement device is internally provided with a block chain module as an independent node in the block chain P2P network, communicates with the metering module in real time, obtains measurement data, participates in each consensus algorithm, and formulates a scheduling operation scheme; and after the scheduling operation scheme is stored in the block chain, driving the electrical equipment to automatically execute the scheduling operation scheme by utilizing the intelligent contract. According to the invention, the nearby consumption of distributed power generation can be promoted, so that the nearby autonomy of community energy is realized, the energy waste is reduced, the dependence on a centralization mechanism is reduced, and the safe and stable operation of the system is ensured.
