基于混合电解槽制氢系统的功率分配技术
Power Distribution Technology Based on Hybrid-electrolyzer Hydrogen Production System
摘要
Abstract
Photovoltaic(PV)electrolytic water hydrogen production technology is an important way of realizing PV accommodation and green power hydrogen production.In fluctuating power input state,there are many problems in the operation stability of the electrolyzer hydrogen production system and the economy of hydrogen production.Aiming at these problems,a PV hydrogen production strategy based on hybrid-electrolyzer hydrogen production system is constructed,using the combination of alkaline electrolyer(AEL)water hydrogen production systems and proton exchange membrane electrolyzer(PEMEL)systems,and the power optimal control technology and capacity configuration method of the hybrid-electrolyzer hydrogen production system are proposed.Based on the combined operation and reasonable configuration of different types of electrolyzers,the performance of hydrogen production is improved.Results show that the quantity of hydrogen production of the hybrid electrolyzer hydrogen production system is improved by 5%compared with the single AEL hydrogen production system.The fluctuation rate and the hydrogen production cost are dramatically reduced compared with the PEMEL hydrogen electrolytic water production system.With the adoption of the power optimization control technology,the quantity of the hydrogen production is increased in the operation state with the same power.When the single electrolyzer is in the fluctuating working condition,the array rotation mode is adopted to ensure the safe operation of the electrolyzer system.关键词
