Optimal Scheduling of Electricity and Hydrogen Integrated Energy System Considering Multiple Uncertainties

Abstract

The spread of renewable energy (RE) generation not only promotes economy and the environmental protection, but also brings uncertainty to power system. As the integration of hydrogen and electricity can effectively mitigate the fluctuation of RE generation, an electricity-hydrogen integrated energy system is constructed. Then, this paper studies the source-load uncertainties and corresponding correlation, as well as the electricity-hydrogen price uncertainties and corresponding correlation. Finally, an optimal scheduling model considering economy, environmental protection and demand response (DR) is proposed. The simulation results indicate that the introduction of the DR strategy and the correlation of electricity-hydrogen price can effectively improve the economy of the system. After introducing the DR, the operating cost of the system is reduced by 5.59%, 10.5%, 21.06% in each season, respectively. When considering the correlation of EP and HP, the operating cost of the system is reduced by 4.71%, 6.47%, 1.4% in each season, respectively.
