Stochastic scheduling of integrated electricity-heat-hydrogen systems considering power-to-hydrogen and wind power
Wind power is often curtailed due to the strong coupling relationship between power and heat supply of combined heat and power units. Power-to-hydrogen (P2H) is a promising technology to integrate the wind power, by which the surplus wind power can be converted into hydrogen and stored in the hydrogen storage. Then, hydrogen can be not only converted into electricity but also sold to the hydrogen market. The comprehensive utilization of hydrogen can increase the flexibility of the energy system. In this paper, the P2H system considering the sales of hydrogen is modeled and integrated into the stochastic dispatch model of the integrated electricity-heat-hydrogen system. The model considers the constraints of the hydrogen storage, sales of hydrogen, electric power systems, and district heating systems. To verify the feasibility and effectiveness of the proposed method, two case studies are simulated and the results show that P2H systems can improve the wind power integration and reduce the operating cost of the system. The installation location of P2H systems has an impact on the system operation. Moreover, the price of hydrogen will influence the operation of P2H systems.
