The electricity-to-hydrogen technology provides a new idea for solving the problem of abandoning wind and light. Aiming at the issue of large-scale environmental protection of hydrogen energy, this article proposes an idea for constructing an electricity-hydrogen integrated station. Based on the function settings of peak shaving and valley filling, renewable energy consumption and hydrogen supply, the power purchase strategies of the integrated station in the main energy and new energy markets are analyzed; Then, an optimized operation model of the electric-hydrogen integrated station considering the market environment 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. Conditions, nonlinear programming tool is use 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 and the ability to absorb renewable energy.
