Integrated energy system-Hydrogen natural gas hybrid energy storage system optimization model based on cooperative game under carbon neutrality

Under the background that carbon emission reduction has become an important research issue in the world, China has put forward the goal of achieving carbon neutrality by 2060. In order to realize the carbon neutralization of Integrated energy system (IES), this paper first constructs the cooperative game model of Integrated energy system- Hydrogen natural gas hybrid energy storage system (IES-HGESS) considering carbon neutralization. Based on the cooperative game theory, this paper analyzes the driving force of cooperative alliance between IES and HGESS, and puts forward the cooperative game model of IES-HGESS. Secondly, based on the cooperative game, it constructs the clearing model of IES-HGESS in the day ahead market and real-time market. Thirdly, in order to realize the long-term and stable cooperation between IES and HGESS, the cooperation gain coefficient was introduced and the income distribution strategy of IES-HGESS was designed. Finally, the paper takes an IES-HGESS as an example to analyze the case, and the analysis of the calculation example shows that the IES-HGESS alliance can increase the net profit of both parties and achieve mutual benefit and win-win results.
