Abstract:

With the accelerated progress on internet information technology，renewable energy technology and electric
power reform，integrated energy service has become an important tactic to improve energy efficiency，reduce energy costs，
and stimulate the competition and cooperation. Blockchain，as a core technology for innovative development in energy
industry，is a good match for the integrated energy service model. By analyzing the service model，an integrated energy
service model with master-slave multi-chain structure based on blockchain was constructed，and the election method for
main chain nodes and the block structure of the energy blockchain were introduced，and finally the operation mode of the
integrated energy service supported by blockchain was expounded. The analysis provides a reference for the development of
the integrated energy model.

Key words: integrated energy service, energy blockchain, energy internet, master-slave multi-chain structure, urgency,
main chain nodes, election method
