Background With the rapid development of renewable energy sources such as wind power, photovoltaic and the like, the installed scale of the renewable energy sources is continuously enlarged, and the occupied ratio of the renewable energy sources in a power system is continuously improved. However, because the wind and light output has the characteristics of intermittence, randomness, volatility and the like, large-scale direct grid connection can bring obvious impact to the peak regulation capacity, stability margin and safe operation of a power grid, and a large amount of renewable energy sources can not be effectively utilized, so that serious energy waste problems such as wind abandoning, light abandoning and the like are formed. In order to promote the in-situ level of new energy, introducing flexible load with rapid power adjustment capability becomes a key technical path. The electrolytic water hydrogen production equipment can flexibly match the fluctuation characteristic of wind and light output by virtue of the characteristics of high response speed, capability of adjusting power in a large range and the like, effectively reduces the impact of new energy grid connection on a power grid, and is an important means for improving the new energy absorption capability and supporting the development of a novel power system. Through converting surplus electric energy into hydrogen, the efficient storage of electric energy can be realized, and energy guarantee can be provided for future low-carbon economy. The method is characterized in that the basic water electrolysis is a common method in the hydrogen production technology by water electrolysis, the core equipment is an alkaline electrolysis tank, the array design of the basic electrolysis tank is usually composed of a plurality of electrolysis tanks connected in series and parallel, in the traditional electrolysis tank control strategy, the influence of the operation time and the start-stop times on the service life of the electrolysis tank is usually ignored, and in the long-term operation process, serious uneven operation time and start-stop times of different electrolysis tanks can be caused, so that the aging degree difference of the different electrolysis tanks is obvious. The aging difference not only causes the reduction of the working efficiency of the system, but also can increase the maintenance cost, and the uneven aging of the electrolytic cells not only improves the maintenance cost of a single unit, but also aggravates the overall maintenance complexity and the energy consumption cost of the system, and particularly, when the single electrolytic cell is aged or failed, if only individual elements are replaced, the maintenance is complex, the cost is high, the performance is difficult to match with new equipment, as part of the electrolytic cells are aged, the operation stability of the electrolytic cells is reduced, more frequent maintenance and calibration are needed, the operation maintenance workload and the shutdown loss are increased, when few electrolytic cells in the array are obviously aged, the operation maintenance cost is further improved for maintaining the stability of the system, the polar plate resistance of the aged electrolytic cells is increased, the local heat production and the energy efficiency are easily reduced, and the failure risks such as overheat, liquid leakage and the like are increased. In conclusion, the uneven aging of the electrolytic cell not only improves the maintenance cost of a single unit, but also aggravates the overall maintenance complexity and the energy consumption cost of the system. Therefore, how to reasonably arrange the electrolytic tanks so that the operation of the electrolytic tanks is more balanced, the service life of the whole system is prolonged, and the electrolytic tanks become an important task for improving the economy and the reliability of the grid-connected type electric hydrogen production system.
