Hydrogen-electric coupled energy storage is an effective way to solve the contradiction between the large-scale development of photovoltaic/wind power new energy and consumption.It is based on the"electric-hydrogen-electricity"(P2P)conversion process,which can regulate the fluctuating wind power generation to the stable power supply required for hydrogen energy storage,and reduce the impact of the volatility and intermittently of local wind power generation on the efficiency of electrolytic water hydrogen production.This paper carried out the design and simulation of the off-grid hydrogen-electric coupl-ing energy storage system,designed the overall system architecture mainly based on wind/light power generation,electro chemical energy storage,hydrogen production and hydrogen storage devices by electrolytic water,built the key unit model and the overall system model with power matching.Based on the actual meteorological input data,the system model was simulated and verified,and the expected regulation effect was achieved.It can provide basis and support for hydrogen electricity conversi-on and renewable energy consumption regulation strategy.
