Abstract

The integration of multi-energy systems is an important feature of energy internet system. The traditional energy systems, such as electric power, thermal power, gas and other energy systems, are operating separately. All kinds of energy systems have been separated and self-made in a long time. They are managed by different departments, and it is difficult to set up a centralized dispatching agency for operation management, which restricts the development of energy internet system greatly. Block chain technology has the main characteristics of decentralization and transparency. Therefore, a decentralization dispatching and operation control mechanism based on block chain technology for multi-energy fusion system is proposed in this paper. Through the establishment of decentralized dispatching agencies for operation management, it is proposed to share the information of energy supply and demand relationship between different energy systems and different regions in multiple energy systems. An optimal operation model of self-dispatching decision-making is established to obtain the results of energy self-dispatching transaction of each energy demand node. Finally, a simulation is conducted of a multi-energy system, and the calculation results verify the effectiveness and feasibility of the self-scheduling decision-making optimization model proposed in this paper.
