Abstract:

Hydrogen and ammonia production from wind power offers a practical solution for addressing the on-site consumption challenges of wind energy in China's "Three North" region. To enhance the economic performance and operational stability of wind-hydrogen-ammonia synthesis systems, this study proposes an optimal allocation strategy that considers multi-factor constraints in source-storage-load coordination. First, a system model for wind turbine-driven hydrogen and ammonia production is established, incorporating variables such as hydrogen production equipment power, energy storage configuration ratio, hydrogen storage tank capacity, grid electricity consumption, annual shutdown frequency, hydrogen and ammonia outputs, and liquid ammonia costs under different operational conditions. Second, an economic objective model is formulated as a boundary condition to guide a source-storage-load collaborative optimization strategy. This strategy identifies optimal output levels for grid electricity extraction, hydrogen storage, and battery energy storage to achieve cost-effective configurations across different scenarios. Finally, using typical annual wind speed data from Urad Middle Banner as a benchmark, an economic comparison is conducted across four working scenarios. Results demonstrate that the proposed control strategy effectively meets field demands, achieving the lowest unit ammonia cost, maximum system output, minimal downtime, and the shortest payback period. This study enhances the local consumption and self-balancing capabilities of wind power systems and offers engineering insights for improving the economic viability of hydrogen and ammonia production based on coordinated source-storage-load operation.
