Referring to fig. 1, fig. 1 is a schematic diagram illustrating steps of a control method for producing hydrogen from new energy according to an embodiment of the present application, and the steps are as follows:
step S100, acquiring electric quantity required by hydrogen production of new energy, and output parameters and minimum operation parameters of a new energy power supply in a preset working time period;
in some embodiments, the new energy power source described in this embodiment and subsequent embodiments may be any new energy power source that can be applied to a grid-connected hydrogen production apparatus in the prior art, and in a specific application, the new energy power source may be, for example, a photovoltaic power generation system, a wind power generation system, and the like, which is not specifically limited in this disclosure.
Correspondingly, because the new energy power supply often has certain limitation or requirement on the working time, taking a photovoltaic power generation system as an example, the new energy power supply can only generate electric energy in the time period with the sunlight, therefore, if the new energy power supply is realized based on the photovoltaic power generation system, the corresponding preset working time period can be set based on the time period with the sunlight in any day; correspondingly, if the wind power generation system adopted by the new energy power supply is adopted, the preset working time period corresponds to the time period of wind power which can enable the wind power generation system to normally generate electric energy. Based on the foregoing, in practical applications, the preset working time period needs to be combined with specific type selection of the new energy power supply, and environmental conditions are flexibly selected.
Step S110, obtaining the rated capacity of the new energy power supply according to the minimum operation parameter, and determining the rated power of the new energy power supply according to power fluctuation;
in some embodiments, the predicted output power value of the new energy power source in the preset working time period can be predicted based on the historical power generation data of the new energy power source or a related prediction system. Moreover, the output power predicted value of the new energy power supply in the preset working time period can be embodied in various forms, for example, a power prediction curve form can be embodied, and the output power predicted value corresponding to each working moment in the preset working time period can be definitely obtained through the curve; for another example, the recording may be performed in the form of an array, and each group of data records the working time and the predicted output power value corresponding to the working time, and of course, the recording may also be performed in other manners, which are not listed here.
And S120, controlling hydrogen production equipment to produce hydrogen in a preset working time period according to the rated power and the rated capacity required by hydrogen production.
In some embodiments, in practical applications, the hydrogen production amount of the hydrogen production equipment is determined every day or within a certain specified time period, and accordingly, the required hydrogen production electric quantity corresponding to the hydrogen production amount is also determined.
Example 2

and S200, controlling the receiving quantity of corresponding parameters of hydrogen production from the new energy source to be corresponding values when only power is taken from the new energy source under the required electric quantity.
And S210, controlling the corresponding parameter receiving quantity of the new energy hydrogen production as an output parameter of the new energy power supply in a preset working time period, and supplementing the output parameter with power corresponding to the minimum operation parameter output by the new energy power supply.
And S220, determining the electric quantity which is provided by the rated capacity of the new energy power supply and can be used for hydrogen production in a preset working time period according to the rated capacity of the new energy power supply to obtain the available hydrogen production electric quantity.
And step S230, determining a target constraint condition of the calculation model according to the corresponding relation between the available hydrogen production electric quantity and the rated power requirement of the new energy power supply.
And S240, controlling the output parameters of the hydrogen production equipment until the electric quantity of the new energy power supply is in the electric quantity corresponding to the output parameters in the preset working time period, so that the new energy power supply absorbs the power fluctuation of the hydrogen production equipment.
And S250, regulating the hydrogen production power output to the hydrogen production equipment by the AC/DC converter in the hydrogen production equipment according to the rated power required by hydrogen production and the actual value of the rated capacity and the relationship between the power required by the lowest hydrogen production and the highest hydrogen production power, so as to control the hydrogen production equipment to produce hydrogen.
In some embodiments, the energy storage system or the controller is further configured to obtain a bus voltage reference value according to a maximum power point of the new energy power source, and control an output voltage of the energy storage system according to the bus voltage reference value; it should be understood that obtaining the reference value of the bus voltage from the maximum power point of the new energy power source is a mature technology and is not described herein again. For example, when the new energy power source is a photovoltaic system, the bus voltage reference value can be obtained according to the maximum power point of the photovoltaic system.
The hydrogen production equipment is also used for controlling the input voltage of the hydrogen production equipment according to the bus voltage reference value and obtaining a first target value of the current loop reference value according to the bus voltage loop; the power control device is also used for obtaining a second target value of the current loop reference value according to the preset proportion electric quantity of the energy storage system and the actual electric quantity of the energy storage system, obtaining a current reference value of the hydrogen production equipment according to the first target value of the current loop reference value and the second target value of the current loop reference value, and controlling the input power of the hydrogen production equipment according to the current reference value. It should be understood that the input power is equal to the input voltage multiplied by the input current of the hydrogen plant, the input voltage of the hydrogen plant is the bus voltage, and the input current of the hydrogen plant can be controlled according to the current reference value, so that the input power of the hydrogen plant can be controlled by controlling the input current of the hydrogen plant on the premise that the bus voltage is controlled.
