Energy Internet is a major innovation in energy development, it involves the concept of Internet of Things, all the existing energy information (distributed generation, supply, consumption) can be connected through the network, get timely feedback, and select control according to demand. Energy development has undergone a micro-energy network, centralized supply, and then to distributed, decentralized, and to achieve ubiquitous state. Now in the distribution of the need for energy stations, there need to achieve synergy among the distribution energy. The Energy Internet distributed collaboration requires artificial intelligence to support its distribution, and distributed optimization synergy in turn requires a lot of artificial intelligence tools. Blockchain technology, as a distributed and shared database technology, has been applied to the concept of energy Internet because of its centrality, transparency, fairness and openness.
