FAQS about Source-grid-load hydrogen storage peak-shaving power station

Does peak shaving affect the power generation capacity of light-storage-hydrogen power generation system?

To improve the capacity of the light-storage-hydrogen power generation system and its influence on the peak shaving effect of the system, the net load curve is compared between the case of peak shaving and frequency modulation and the case of no energy storage (no peak shaving and frequency modulation), as shown in Fig. 6.

Does energy storage play a role in peak shaving?

This is because the light output without peak shaving and frequency modulation is much higher than that without peak shaving and frequency modulation, and the low net load of the system shows that energy storage plays a role in peak shaving in the system.

What are the uses of hydrogen energy in a power grid?
