Researchers Develop Post-Disaster Emergency Dispatching Strategy for Hydrogen Energy Port

In a study published in the July 2025 issue of the Journal of Engineering, a team of researchers from China Three Gorges University have developed a post-disaster emergency dispatching strategy for hydrogen energy ports that considers frequency constraints. The researchers aim to address the severe load interruption and economic losses caused by extreme disasters in port distribution networks. The strategy involves establishing an operational model for port hydrogen energy systems and incorporating frequency stability constraints of distribution networks. Simulation results demonstrate the effectiveness of the proposed strategy in reducing post-disaster losses while ensuring power supply reliability and grid security.

Key Takeaways:

• The researchers proposed a post-disaster emergency dispatching strategy for hydrogen energy ports that considers frequency constraints to address load interruption and economic losses.
