Abstract:
Objective In order to solve the problem of the construction of a new power system under the dual carbon strategic goal, this paper discusses the realization of fuel synthesis through carbon capture and hydrogen electrolysis technology, and studies the effective combination of virtual power plant and power-to-fuel technology, so as to promote large-scale new energy consumption and reduce carbon dioxide emissions, and realize the sustainable development of low-carbon energy.
Method To solve this problem, a multi-energy collaborative optimization model of virtual power plant considering power-to-fuel was established. Firstly, the types of power-to-fuel and their related technical principles are introduced, and the corresponding devices were modeled. Secondly, the multi-energy complementary structure and operation mode of the virtual power plant integrating electricity, heat, hydrogen, fuel and carbon dioxide were determined. Then, a collaborative optimization model of virtual power plant was constructed under different carbon price mechanisms.
Result The feasibility of the proposed model is verified by simulation and comparison of different scenarios, and the results show that the virtual power plant considering power-to-methanol has significant advantages in improving economic and environmental benefits compared with the virtual power plant considering power-to-methane.
Conclusion This paper provides theoretical guidance for the construction of virtual power plants in the context of achieving the dual carbon goals and distributed energy consumption.
