Description
technical field [0001] The invention relates to the technical field of electrolyzed water, in particular to a non-grid-connected wind power electrolyzed water hydrogen production system and a coordinated control method thereof. Background technique [0002] Non-grid-connected wind power technology is a wind power generation technology that directly applies wind power to high energy-consuming industries, and can effectively deal with the impact of wind power itself on the power grid due to intermittency and volatility. The non-grid-connected wind power hydrogen production composed of non-grid-connected wind power + electrolytic water hydrogen production has realized the green energy conversion of "wind energy-electric energy-hydrogen energy". In addition, the use of hydrogen energy has completely achieved zero carbon emissions and zero pollution, forming a 100 % renewable energy cycle system. [0003] In the non-grid-connected wind power electrolysis water hydrogen productio...
