Coordinated Optimization of Hydrogen Integrated Energy System Considering Demand Response

To respond to China’s dual carbon policy, improving energy efficiency, and reducing the dependence on the superior network for energy supply, this paper proposes a coordinated optimization strategy of hydrogen integrated energy system with demand response. Firstly, hydrogen-related energy equipment such as electrolyzers, hydrogen fuel cells, and hydrogen storage tanks are introduced to give full play to the low-carbon cleanliness of hydrogen energy and promote the deep decarbonization of the system. Secondly, the demand response strategy is designed to guide users in pursuing optimal energy efficiency by comprehensively studying the load characteristics of various loads on the user side. Finally, the system is considered to participate in carbon market trading, and a stepped carbon trading mechanism is introduced to calculate the system operation costs. The simulation results show that the proposed coordinated optimization strategy can improve the efficiency of energy equipment, reduce the operating pressure by adjusting loads, realize the horizontal transfer of multiple energy sources in time, and achieve a balance between low carbon and economy.
