Blockchain-based Energy Transaction Model for Multiple Energy Hubs

Abstract

Promoting the effective use of energy with the Energy Hub(EH) is an important part of the construction of the Energy Internet. In this paper, an energy transaction model for the Multiple Energy Hub System(MEHS) based on blockchain technology is proposed, which is a distributed system composed of multiple energy hubs. Firstly, the concept of the EH and the current research and application of the energy hub technology are introduced. Then the definition, structure, classification, consensus mechanism, and smart contract of blockchain technology are described. The feasibility of applying blockchain technology to energy network is analyzed. Thirdly, the model structure and energy transaction framework based on blockchain technology are established. Meanwhile, a series of algorithms that give transaction priority are designed. Finally, the model of MEHS based on blockchain technology is given in detail, and compared with the traditional scheduling model to illustrate the superiority of using blockchain technology.
