An optimal scheduling strategy for an integrated energy system considering user-side electricity and hydrogen demand response

In order to solve the problems of increasing the total operation cost and load difference between peaks and valleys due to the low participation of users in energy dispatching in the current integrated energy system, this paper proposes an optimal scheduling strategy for integrated energy system considering the user-side electricity and hydrogen demand response. The user-side demand response electricity and hydrogen load is divided into translational, transferable and reducible loads according to load types, and participating in dispatching respectively. The compensation of demand response is converted into the operation cost of the comprehensive energy system. Finally, a comprehensive energy system economic scheduling model with the minimum total operation cost as the goal was established. Cplex was used to solve the calculation example, and the optimization results of demand response electricity and hydrogen load participating in scheduling were obtained under three scenarios. The simulation results show that the electricity and hydrogen coupling scheduling and the interaction between the electric and hydrogen loads in demand response can significantly reduce the operating cost of the system and reduce the peak-valley load difference.
