[0021] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present disclosure. However, it should be clear to those skilled in the art that the present disclosure may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obstructing the description of the present disclosure with unnecessary details.

[0022] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1 , Figure 1 A flow chart of a control method for a hydrogenation and hydrogen production integrated station provided in an embodiment of the present disclosure, the method comprising:

[0024] S101: adjusting the feed ratio of each raw material of the hydrogen production equipment based on the reactant concentration of the hydrogen production equipment in the integrated hydrogenation and hydrogen production station; the reactant concentration is the mixed concentration of each raw material in the hydrogen production equipment, and the feed ratio is the feed ratio of each raw material in the hydrogen production equipment.

[0025] In this embodiment, the hydrogen production equipment can produce hydrogen by electrolysis of water, natural gas reforming, alcohols, etc. Taking the electrolysis of water as an example, an electrolyte, such as commonly used sodium hydroxide or potassium hydroxide, is added to the water during the hydrogen production process, and then electricity is passed between the two electrodes. After power is turned on, water molecules undergo electrolysis reaction under the action of the electrolyte to generate hydrogen and oxygen. During the process of hydrogen production by electrolysis of water, the concentration of the electrolyte (that is, the concentration of the reactants) is monitored in real time, and the feed ratio of each raw material of the hydrogen production equipment is adjusted according to the concentration of the reactants, so as to ensure that the concentration of the electrolyte is within the set range to ensure the efficiency of hydrogen production.

[0026] Taking alcohol hydrogen production as an example, in the hydrogen production process, alcohol raw materials (including low-carbon alcohols such as methanol or ethanol) and desalted water are mixed in a certain proportion, enter the gasification superheater for gasification and superheating to the required temperature, and complete the gas phase catalytic cracking and conversion reaction under the action of the catalyst to generate conversion gas containing hydrogen, carbon dioxide and a small amount of carbon monoxide. In the process of alcohol hydrogen production, the concentration of the reactants is monitored in real time, and the feed ratio of each raw material of the hydrogen production equipment is adjusted according to the concentration of the reactants, which can ensure that the concentration of the reactants is within the set range to ensure the efficiency of hydrogen production.

[0027] S102: Determine the hydrogen production efficiency of the hydrogen production equipment based on the operating parameters of the hydrogen production equipment.

[0028] In this embodiment, the degree of reaction between the raw materials during the hydrogen production process will be affected by operating parameters such as temperature or pressure, thereby affecting the hydrogen production efficiency. Taking the water electrolysis hydrogen production equipment as an example, the higher the temperature of the electrolytic cell, the higher the hydrogen production efficiency. However, too high a temperature will cause the water in the electrolyte to evaporate, thereby affecting the hydrogen production efficiency; and the pressure will also affect the distribution and movement speed of the gas in the electrolytic cell, which will directly affect the efficiency of the electrolysis reaction and the rate of hydrogen production. Therefore, the current hydrogen production efficiency can be determined by monitoring the operating parameters of the hydrogen production equipment.

[0029] S103: Determine the feed rate of each raw material of the hydrogen production equipment based on the hydrogen production efficiency and feed ratio of the hydrogen production equipment, and control the hydrogenation and hydrogen production integrated station based on the feed rate of each raw material.

[0030] In this embodiment, by real-time monitoring of the reactant concentration, the feed ratio of each raw material of the hydrogen production equipment can be adjusted according to the reactant concentration. On this basis, the feed rate of each raw material is adjusted according to the hydrogen production efficiency of the hydrogen production equipment, and the hydrogen production rate of the hydrogen production equipment can be adjusted according to the hydrogen production efficiency of the hydrogen production equipment.

[0031] It can be concluded from the above that in the disclosed embodiment, the hydrogen production equipment generates hydrogen by chemically reacting the raw materials (reactants). As the reaction process proceeds, the concentration of the reactants will continue to decrease. In order to ensure the efficiency of hydrogen production, the present embodiment monitors the concentration of the reactants in real time and adjusts the feed ratio of each raw material of the hydrogen production equipment according to the concentration of the reactants. At the same time, considering that the operating parameters (including temperature or pressure, etc.) of the hydrogen production equipment will change during the reaction process, thereby affecting the efficiency of hydrogen production. Therefore, on the basis of ensuring the feed ratio of each raw material, the present embodiment further adjusts the feed rate of each raw material according to the hydrogen production efficiency, so that when the hydrogen production efficiency is high, the feed rate is fast and the hydrogen production rate is fast, and when the hydrogen production efficiency is low, the feed rate is slow and the hydrogen production rate is slow, so as to improve the overall hydrogen production efficiency, thereby improving the energy utilization efficiency of the hydrogenation and hydrogen production integrated station.

[0032] In one embodiment of the present disclosure, adjusting the feed ratio of each raw material of the hydrogen production equipment based on the reactant concentration of the hydrogen production equipment in the hydrogenation and hydrogen production integrated station includes:

[0033] In response to the reactant concentration being greater than a first threshold, the feed ratio is reduced by a first step.

[0034] In response to the reactant concentration being less than a second threshold, the feed ratio is increased by a second step size.

[0035] In this embodiment, still taking the electrolysis water hydrogen production equipment as an example, the reactant concentration is the ratio of electrolyte and water. To ensure the efficiency of hydrogen production, the reactant concentration needs to be maintained between the first threshold and the second threshold. Specifically, an initial feed ratio can be pre-set, and on the basis of the initial feed ratio, the feed ratio is adjusted in real time as the reaction proceeds. For example, when the reactant concentration is detected to be less than the second set threshold for the first time, the second step length can be increased on the basis of the initial feed ratio to obtain the first feed ratio, and then if the reactant concentration is detected to be still less than the second threshold, the second step length can be increased on the basis of the first feed ratio to obtain the second feed ratio, and so on, until the reactant concentration is between the second threshold and the first threshold. If the reactant concentration is detected to be greater than the first threshold after adding each raw material, the first step length can be reduced on the basis of the current feed ratio, and so on, until the reactant concentration is between the second threshold and the first threshold. The first threshold, the second threshold, the first step length and the second step length are all preset constants, and those skilled in the art can set them according to actual needs.

[0036] In one embodiment of the present disclosure, the operating parameters of the hydrogen production equipment include temperature and pressure, and determining the hydrogen production efficiency of the hydrogen production equipment based on the operating parameters of the hydrogen production equipment includes:

[0037] A first efficiency parameter is calculated based on the temperature of the hydrogen generation facility and a temperature threshold.

[0038] A second efficiency parameter is calculated based on the pressure of the hydrogen generation facility and the pressure threshold.

[0039] A third efficiency parameter is calculated based on the first efficiency parameter and the second efficiency parameter.

[0040] The hydrogen production efficiency of the hydrogen production equipment is calculated based on the third efficiency parameter and the efficiency reference value.

[0041] In this embodiment, the temperature threshold of the hydrogen production equipment includes an upper temperature limit and a lower temperature limit. Between the upper temperature limit and the lower temperature limit, the hydrogen production efficiency increases with the increase of temperature. Therefore, the first efficiency parameter can be calculated by the following formula: :

[0042]

[0043] Where T is the current temperature, is the upper temperature limit, is the lower limit of temperature.

[0044] Similarly, the pressure threshold of the hydrogen production equipment includes an upper pressure limit and a lower pressure limit. Between the upper pressure limit and the lower pressure limit, the hydrogen production efficiency increases with the increase of pressure. Therefore, the second efficiency parameter can be calculated using the following formula: :

[0045]

[0046] Where P is the current pressure, is the upper limit of pressure, is the lower limit of pressure.

[0047] On the basis of obtaining the first efficiency parameter and the second efficiency parameter, the influence of the first efficiency parameter and the second efficiency parameter on the hydrogen production efficiency can be comprehensively considered to obtain a third efficiency parameter. For example, the first efficiency parameter and the second efficiency parameter can be weighted summed to obtain the third efficiency parameter, and then the hydrogen production efficiency of the hydrogen production equipment can be calculated based on the third efficiency parameter and the efficiency reference value. The efficiency reference value can be the rated efficiency of the hydrogen production equipment.

[0048] In one embodiment of the present disclosure, the feed rate of each raw material of the hydrogen production equipment is determined based on the hydrogen production efficiency and feed ratio of the hydrogen production equipment, including:

[0049] The first mapping relationship is searched based on the hydrogen production efficiency of the hydrogen production equipment to obtain a feed rate reference value of the hydrogen production equipment.

[0050] The feed rate of each raw material of the hydrogen production equipment is determined based on the feed rate reference value and the feed ratio.

[0051] In this embodiment, each raw material can be regarded as a whole and uniformly referred to as a reactant, and the feed rate of the reactant can be referred to as a feed rate reference value. On this basis, a first mapping relationship between the hydrogen production efficiency and the feed rate reference value can be pre-constructed, and then during the hydrogen production process, the current feed rate reference value can be quickly determined according to the hydrogen production efficiency and the first mapping relationship.

[0052] The feed rate of each raw material can be obtained by multiplying the feed rate reference value by the feed ratio of each raw material.

[0053] In one embodiment of the present disclosure, the control method of the hydrogenation and hydrogen production integrated station further includes:

[0054] The traffic flow information of the hydrogen refueling and hydrogen production integrated station is determined based on the date information.

[0055] A feed speed reference value is determined based on the vehicle flow information.

[0056] In this embodiment, it is considered that there will be different traffic flows on different dates, and thus different demands for hydrogen refueling on different dates. For example, on weekdays, people may rely more on public transportation systems, while on weekends and holidays, people may be more inclined to use private cars, especially during long holidays such as the Spring Festival and National Day, when people will choose to travel by car, thereby increasing the traffic flow of the hydrogen refueling and hydrogen production integrated station, and it is necessary to correspondingly increase the hydrogen production speed of the hydrogen refueling and hydrogen production integrated station.

[0057] Specifically, the corresponding relationship between the traffic volume and the feed speed reference value can be pre-built, and then the feed speed reference value of the corresponding date can be obtained according to the traffic volume information of different dates, and the feed speed of each raw material can be determined by the feed speed reference value.

[0058] This embodiment determines the vehicle flow information according to the date information, and then determines the corresponding feed speed reference value according to the vehicle flow information, so as to adjust the feed speed of each raw material according to the change of date, and then adjust the hydrogen production speed of the hydrogenation and hydrogen production integrated station according to the change of date, so that the hydrogenation and hydrogen production integrated station can better meet the hydrogenation needs of users.

[0059] In one embodiment of the present disclosure, determining the vehicle flow information of the hydrogenation and hydrogen production integrated station based on date information includes:

[0060] In response to the date information belonging to the first category of date information, the first vehicle flow rate is determined as the vehicle flow rate information of the integrated hydrogen refueling and hydrogen production station.

[0061] In response to the date information belonging to the second category of date information, the second vehicle flow is determined as the vehicle flow information of the integrated hydrogen refueling and hydrogen production station.

[0062] In this embodiment, the first type of date information is a weekend or holiday, and the second type of date is a working day. The average value of the traffic flow corresponding to the first type of date information can be pre-counted to obtain the first traffic flow, and the average value of the traffic flow corresponding to the second type of date information can be counted to obtain the second traffic flow. During the operation of the hydrogenation and hydrogen production integrated station, if a certain date is a holiday, the first traffic flow is determined as the traffic flow information of the hydrogenation and hydrogen production integrated station, and the hydrogen production speed is determined by the traffic flow information; if a certain date is a working day, the second traffic flow is determined as the traffic flow information of the hydrogenation and hydrogen production integrated station, and the hydrogen production speed is determined by the traffic flow information.

[0063] In one embodiment of the present disclosure, there is a positive correlation between the vehicle flow information and the feed speed reference value.

[0064] In this embodiment, the vehicle flow information and the feed speed reference value are positively correlated, that is, the feed speed reference value increases with the increase of vehicle flow. Specifically, the feed speed reference value V can be calculated using the following formula:

[0065]

[0066] Among them, a is a preset constant and L is the traffic flow information.
