Research on Full Capacity Deep Peak Shaving Scheme for Thermal Power Units with Hydrogen Electric Dual Supply
Thermal power enterprises are facing a dual dilemma of increased costs caused by high coal prices and decreased revenue due to competition in new energy. Carrying out technological transformation to improve deep peak shaving performance and enrich business types is the key to the future survival and development of thermal power plants. By using hydrogen energy storage devices combined with peak shaving thermal power units,a low-cost hydrogen production and efficient hydrogen consumption industry chain is constructed. Based on the establishment of an electrochemical reaction model,the process flow is simulated using Aspen,and the energy efficiency of the hydrogen fire coupling system is calculated to reach 50.15％,which is more than 10％ higher than the conventional electrolytic water hydrogen production peak shaving scheme. The research results indicate that hydrogen electric dual supply thermal power units can bring significant economic benefits to thermal power enterprises.
