Demand Response Strategy of Integrated Energy System Considering Electricity-Hydrogen Energy Storage Under The Carbon Market

With the improvements of energy coupling and carbon market mechanism, the traditional power demand response no longer meets the current development status of the integrated energy system (IES). In order to improve the integrated demand response capability of IES, a bi-level model of IES-user considering carbon market and electric-hydrogen energy storage is established. The upper-level is IES model that considers the investment cost of electricity-hydrogen energy storage, carbon cost, and multi-energy coupling, and the lower-level is users model that includes the transferable and reduced loads. Then, the operator is introduced as the park manager. A framework of stackelberg game between operators and users is constructed, and the objective function is to maximize the operator's profit and minimize the user's cost. Finally, the case study analyzes the impact of electricity-hydrogen energy storage on the demand response effect under the carbon market, and the impact of the carbon market and electricity-hydrogen energy storage on IES carbon emissions. And the electric-hydrogen energy storage capacity under different conditions is configured. The results verify the effectiveness of the interactive method.
