Abstract: To realize intelligent distributed micro-energy trading, based on the structure, characteristics and application of blockchain technique, this paper analyzes the general process of Brooklyn case of electrical energy trading between consumers and power generation system. It proposes the information and physical processes of electric energy transaction between electricity consumers and generations using blockchain technique. And the three nodes are established in the private chain of blockchain to simulate the information matching, authentication and value transfer of electricity transaction. The challenges and advantages of blockchain technique applied in micro-energy trading are analyzed and summarized.
