Control method, device and system of solar hydrogen production system and storage medium

Abstract

The invention relates to a control method, device and system of a solar hydrogen production system and a storage medium, and belongs to the field of electrolytic hydrogen, the method is applied to a central controller in the solar hydrogen production system, and the method comprises the following steps: determining a power grid power value output by a solar energy collection device; under the condition that the power grid power value is larger than or equal to the preset multiplying power of the rated power of the hydrogen production equipment, the working state of each hydrogen production equipment in the solar hydrogen production system is controlled according to the power grid power value and the rated power; and under the condition that the power grid power value is smaller than the preset multiplying power of the rated power, all the hydrogen production equipment is controlled to enter a shutdown heat preservation state. Parts of equipment are automatically allocated to shut down or work according to power grid fluctuation in multi-equipment parallel combined operation, an automatic heat preservation treatment mechanism is adopted, it is guaranteed that the shut-down equipment can be rapidly and stably started next time, and efficient operation of the equipment is achieved.

Description

technical field [0001] The present disclosure relates to the field of electrolysis of hydrogen, and in particular, to a control method, device, system and storage medium for a solar-powered hydrogen production system. Background technique [0002] Solar hydrogen production is regarded as one of the most promising hydrogen production methods. The technology that combines solar power generation and water electrolysis to produce hydrogen into a system is the current mainstream development direction. Hydrogen production from solar energy realizes the production of clean energy from clean energy, and can effectively absorb photovoltaic power generation, and can realize the effective combination application between two important new energy sources.

AI Technical Summary

Problems solved by technology

[0003] Alkaline electrolytic water hydrogen production technology is still the mainstream of commercial scale. The maximum capacity of a single alkaline electrolytic water hydrogen production equipment can reach 1000Nm3 / h, but a single equipment cannot meet the demand for hydrogen consumption in large-scale chemical, metallurgical and other industries. It is necessary to rely on multiple hydrogen production equipment to jointly produce hydrogen to meet the enterprise's demand for hydrogen consumption

However, solar power generation has the characteristics of intermittent power generation, day and night differences, time period differences, weather differences, etc. In related technologies, traditional hydrogen production equipment is mainly controlled by a single unit on the premise of providing stable power supply, lacking systematic Global analysis and scheduling mechanism, traditional hydrogen production control can no longer adapt to the control of large-scale parallel joint operation of multiple equipment
