Research on optimal operation strategy of fuel cell vehicle charging-discharging-storage integrated station

Abstract

Abstract The construction of energy supply facilities supporting fuel cell vehicles is the basis for the development of fuel cell vehicles. Aiming at the large-scale environmental protection supply of hydrogen energy for fuel cell vehicles, this paper proposes a construction idea and function setting for a fuel cell vehicle integrated station. Then, an optimized operation model of the fuel cell vehicle charging-discharging-storage integrated station is established. The model takes the total operating cost of the integrated station as the objective function, and considers the power balance and constraints of the electric-hydrogen system in the integrated station. Nonlinear programming tool is used to solve the model. It is verified by calculation examples that the integrated station proposed in this paper can effectively improve the power grid’s peak and frequency modulation capabilities based on the total daily income of ¥25,431, and increase the renewable energy consumption rate from 48.0% to 84.6%.
