Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a modular water electrolysis hydrogen production system and a control method thereof. Background technique [0002] With the proposal of the 3060 double carbon target, hydrogen is gradually being mentioned as an energy carrier because of its green and environmental protection characteristics. Among many hydrogen production technologies, water electrolysis hydrogen production technology is considered to be the mainstream hydrogen production technology in the future, because when it is coupled with renewable energy, the entire hydrogen production process can truly achieve zero carbon. However, the current hydrogen production capacity of a single electrolyzer is relatively small, and it is difficult to meet the rapid growth of hydrogen demand in the future industry and other fields. At the same time, the volatility of renewable energy will also bring hidden dangers to the safety...
