[0054] With reference to the drawings, the technical solutions in the embodiments of the present application will be clearly described below. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art are within the scope of the present application.
[0055] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a particular order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and are not limited in number, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the front and rear associated objects are in an "or" relationship.
[0056] In the present application, the phrase "embodiments" means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present application can be combined with other embodiments.
[0057] The control method of the hydrogen production system provided by the embodiments of the present application can be executed by an electronic device or a functional module or functional entity in the electronic device capable of realizing the control method of the hydrogen production system. The electronic device mentioned in the embodiments of the present application includes but is not limited to a central processing unit, a microprocessor, a digital signal processor, an artificial intelligence processor, a graphics processor, an application specific integrated circuit, a network processor, a field programmable gate array or other programmable logic device, a gate circuit, a transistor, a discrete hardware component, etc. The control method of the hydrogen production system provided by the embodiments of the present application will be described below taking the electronic device as an example.
[0058] The application scenarios of large-scale hydrogen production are expanding. In order to reduce the cost of green hydrogen production and improve the efficiency of new energy stations, it is particularly important to fully utilize the resources of hydrogen production stations and flexibly schedule hydrogen production units. When hydrogen is used as a chemical raw material to produce ammonia, stable and sufficient supply is needed to ensure the efficiency of the production process and the quality of ammonia. Because the scale of hydrogen storage in the tank is small, the hydrogen production station must ensure stable hydrogen production and minimize fluctuations. If the station also needs to meet other hydrogen demand, such as supplementing hydrogen for hydrogenation stations, the demand is usually intermittent.
[0059] However, in the related art, the control strategy of the hydrogen production system is often designed only for a single hydrogen use scenario. When multiple hydrogen use demands exist simultaneously, especially when the demands have large differences in nature, such a single-scenario control strategy is no longer applicable. Not only can it not effectively cope with complex and variable hydrogen use demands, but it can also lead to waste of hydrogen production resources, seriously affecting the efficient and flexible operation of the hydrogen production site.
[0060] To solve the above problems, the embodiments of the present application provide a control method of a hydrogen production system. The control method of the hydrogen production system, device, hydrogen production system and electronic equipment provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments and their application scenarios.
[0061] Figure 1 is a flowchart of the control method of the hydrogen production system provided by the embodiments of the present application, as Figure 1 indicated, the control method of the hydrogen production system includes steps 110, 120 and 130.
[0062] Step 110, obtaining information of hydrogen use sites and hydrogen use demands of each hydrogen use site;
[0063] It is easy to understand that the hydrogen production site control unit obtains the information of the hydrogen use sites and the hydrogen use demands of each hydrogen use site by interacting with the hydrogen use site control unit.
[0064] Optionally, the information of the hydrogen use sites includes at least one of the number of the hydrogen use sites, the hydrogen use priority of each hydrogen use site, and the hydrogen use scenario corresponding to the hydrogen use site.
[0065] Optionally, the hydrogen use scenario corresponding to the hydrogen use site includes ammonia production, methanol production, hydrogen use in hydrogenation stations, hydrogenation of natural gas, hydrogen storage, etc.
[0066] Step 120, dividing each hydrogen production unit in the hydrogen production site according to the information of the hydrogen use sites and the hydrogen use demands of each hydrogen use site, to obtain a plurality of hydrogen production groups, wherein each hydrogen production group includes at least one hydrogen production unit, and one hydrogen production group corresponds to one hydrogen use site;
[0067] It is easy to understand that the hydrogen production site control unit divides each hydrogen production unit in the hydrogen production site according to the information of the hydrogen use sites and the hydrogen use demands of each hydrogen use site, to obtain a plurality of hydrogen production groups.
[0068] Optionally, the hydrogen production site control unit can evenly divide each hydrogen production unit in the hydrogen production site, for example, there are N hydrogen production units in the hydrogen production site in total, and each two hydrogen production units form a hydrogen production group, and there are N / 2 hydrogen production groups in total.
[0069] Optionally, the hydrogen production station control unit can perform non-equal division on each hydrogen production unit in the hydrogen production station. For example, there are N hydrogen production units in the hydrogen production station, and M hydrogen production units correspond to one hydrogen production group. The value of M can be 1, 2, …, N. When M = N, the N hydrogen production units in the hydrogen production station correspond to one hydrogen production group.
[0070] It should be noted that each hydrogen production group includes at least one hydrogen production unit, and one hydrogen production group corresponds to one hydrogen consumption station. Each hydrogen production unit includes at least one electrolytic cell, and one hydrogen production unit corresponds to one gas-liquid separation and purification unit.
[0071] Optionally, the electrolytic cell can be a proton exchange membrane electrolytic cell, an alkaline electrolytic cell, a solid oxide electrolytic cell, etc. The form of the electrolytic cell is not limited in the embodiments of the present application.
[0072] In step 130, according to the division of each hydrogen production group, the state of the valve between the hydrogen output end of each hydrogen production unit in the hydrogen production group and the hydrogen output buffer device is set. The first end of the hydrogen output buffer device is connected to the valve, the second end of the hydrogen output buffer device is connected to the corresponding hydrogen consumption station, and the hydrogen output buffer device and the hydrogen consumption station are one-to-one corresponding.
[0073] It is easy to understand that the hydrogen production station control unit sets the state of the valve between the hydrogen output end of each hydrogen production unit in each hydrogen production group and the hydrogen output buffer device according to each hydrogen production group. The hydrogen of the hydrogen production unit is delivered to the hydrogen consumption station through the hydrogen output end and the hydrogen output buffer device. The hydrogen output end of each hydrogen production unit is controlled by the valve and can be selectively connected to the hydrogen output buffer device of a certain hydrogen consumption station.
[0074] It should be noted that the hydrogen output buffer device can make the hydrogen pressure delivered to the hydrogen consumption station more stable. For example, the hydrogen output buffer device can be at least one of a hydrogen storage device and a buffer tank.
[0075] It is worth noting that the first end of the hydrogen output buffer device is connected to the valve, the second end of the hydrogen output buffer device is connected to the corresponding hydrogen consumption station, the hydrogen production station control unit can control whether to deliver hydrogen to the hydrogen consumption station by controlling the opening and closing of the valve, and the hydrogen output buffer device and the hydrogen consumption station are one-to-one corresponding.
[0076] The valve can be controlled locally or remotely by the hydrogen production station control unit. Through the control of the valve, the hydrogen production unit can select the hydrogen consumption scene.
[0077] Figure 2 FIG. 1 is a structural schematic diagram of a hydrogen production unit connecting a hydrogen output buffer device provided by the embodiments of the present application, as shown in Figure 2As shown, the hydrogen production unit can be connected with N valves, each of which is connected with a corresponding hydrogen-using station through a hydrogen output buffer device. By controlling the opening and closing states of the valves, the hydrogen produced by the hydrogen production unit can be delivered to a certain hydrogen-using station.
[0078] The control method of the hydrogen production system provided by the embodiments of the present application divides each hydrogen production unit in the hydrogen production station by obtaining the information of the hydrogen-using stations and the hydrogen-using demands of each hydrogen-using station, obtains a plurality of hydrogen production groups, sets the state of the valve between the hydrogen output end of each hydrogen production unit in each hydrogen production group and the hydrogen output buffer device, can select different hydrogen-using scenarios, fully utilizes the resources of the hydrogen production station, avoids the influence of fluctuations between different hydrogen-using scenarios, is conducive to efficient and flexible operation of the hydrogen production station, and improves the control freedom and practicality of the hydrogen production station.

[0083] Optionally, the hydrogen output buffer device can be a hydrogen storage device, which can store excess hydrogen and also stabilize the pressure of the hydrogen, so that the hydrogen can be delivered to the hydrogen-using station stably.
[0084] Illustratively, the hydrogen storage device can be a hydrogen storage tank, a high-pressure storage tank, a liquid hydrogen storage tank, a high-pressure gas cylinder, an adiabatic container, or other devices for storing hydrogen. The storage form of the hydrogen can be one or more of gaseous, liquid, and solid.
[0085] Optionally, the hydrogen output buffer device can be a buffer tank, which can buffer the pressure of the hydrogen, so that the hydrogen can be delivered to the hydrogen-using station stably.
[0086] Optionally, the hydrogen output buffer device can be a buffer tank and a hydrogen storage device, a first end of the buffer tank is connected with the valve, a second end of the buffer tank is connected with a first end of the hydrogen storage device, and a second end of the hydrogen storage device is connected with the corresponding hydrogen-using station. The buffer tank is used to buffer the pressure of the hydrogen, so that the hydrogen can be delivered to the hydrogen-using station stably. The hydrogen storage device is used to store the hydrogen produced by the hydrogen production station.
[0087] It should be noted that the hydrogen output buffer device can be set according to specific scenarios and applications, and the embodiments of the present application do not make any limitation.
[0088] In the technical solution, the hydrogen output buffer device is used as a connecting passage between the valve and the hydrogen-using station, so that the hydrogen can be more smoothly delivered to the hydrogen-using station, the excess hydrogen can be stored, the resources of the hydrogen production station can be fully utilized, the influence of fluctuations between different hydrogen-using scenarios can be avoided, the hydrogen production station can be efficiently and flexibly operated, and the control freedom and practicability of the hydrogen production station are improved.
[0089] In an embodiment of the present application, the information of the hydrogen-using station includes at least one of the following: the number of hydrogen-using stations, the hydrogen-using priority of each hydrogen-using station, and the hydrogen-using scenario corresponding to the hydrogen-using station.
[0090] Optionally, the information of the hydrogen-using station includes the number of hydrogen-using stations and the hydrogen-using priority of each hydrogen-using station. For example, the number of hydrogen-using stations is 5, which are hydrogen-using station 1, hydrogen-using station 2, hydrogen-using station 3, hydrogen-using station 4, and hydrogen-using station 5, and the hydrogen-using priority of the hydrogen-using station is ranked as: hydrogen-using station 1> hydrogen-using station 2> hydrogen-using station 3> hydrogen-using station 4> hydrogen-using station 5.
[0091] Optionally, the information of the hydrogen-using station includes the number of hydrogen-using stations, the hydrogen-using priority of each hydrogen-using station, and the hydrogen-using scenario corresponding to the hydrogen-using station. For example, the number of hydrogen-using stations is 5, which are hydrogen-using station 1, hydrogen-using station 2, hydrogen-using station 3, hydrogen-using station 4, and hydrogen-using station 5, the hydrogen-using scenario corresponding to hydrogen-using station 1 is an ammonia production scenario, the hydrogen-using scenario corresponding to hydrogen-using station 2 is a methanol production scenario, the hydrogen-using scenario corresponding to hydrogen-using station 3 is a hydrogenation station hydrogen-using scenario, the hydrogen-using scenario corresponding to hydrogen-using station 4 is a natural gas hydrogenation scenario, and the hydrogen-using scenario corresponding to hydrogen-using station 5 is a hydrogen storage scenario, and the hydrogen-using priority of the hydrogen-using station is ranked as: hydrogen-using station 1> hydrogen-using station 2> hydrogen-using station 3> hydrogen-using station 4> hydrogen-using station 5.
[0092] It should be noted that the information of the hydrogen-using station can be set according to specific scenarios and applications, and the embodiments of the present application are not limited.
[0093] In the technical solution, by obtaining the information of the hydrogen-using station, the hydrogen production station can be allocated according to the number of hydrogen-using stations, the hydrogen-using priority of each hydrogen-using station, and the hydrogen-using scenario corresponding to the hydrogen-using station, which is beneficial to efficient and flexible operation of the hydrogen production station, and improves the control freedom and practicability of the hydrogen production station.
[0094] In an embodiment of the present application, the method further includes:
[0095] allocating the hydrogen production power of each hydrogen production group according to the hydrogen-using priority of each hydrogen-using station, the hydrogen demand of each hydrogen-using station, and / or the proportion of the hydrogen production unit corresponding to each hydrogen-using station, and the new energy input power;
[0096] Control the hydrogen production groups to work according to the allocated hydrogen production power.
[0097] Optionally, the hydrogen production station control unit allocates the hydrogen production power of each hydrogen production group according to the hydrogen use priority of each hydrogen use station, the hydrogen use demand of each hydrogen use station, the proportion of the hydrogen production unit corresponding to each hydrogen use station, and the new energy input power, and controls each hydrogen production group to work according to the allocated hydrogen production power.
[0098] Optionally, the hydrogen production station control unit allocates the hydrogen production power of each hydrogen production group according to the hydrogen use priority of each hydrogen use station and the proportion of the hydrogen production unit corresponding to each hydrogen use station, and controls each hydrogen production group to work according to the allocated hydrogen production power.
[0099] It should be noted that the hydrogen use station control unit collects information and controls the hydrogen use equipment and the hydrogen output buffer equipment, and obtains the hydrogen use plan (i.e., the hydrogen use demand). The hydrogen use station control unit and the hydrogen production station control unit interact with each other to jointly determine the control method of the hydrogen production station and the hydrogen use station.
[0100] Figure 3 is a schematic diagram of the hydrogen production station and the hydrogen use station provided by the embodiment of the present application, as shown in Figure 3 The hydrogen production station is connected to the new energy station and the power grid at one end, and is connected to the hydrogen use station through the hydrogen output buffer equipment at the other end. The hydrogen production station control unit allocates the hydrogen production groups according to the hydrogen use priority of each hydrogen use station and the hydrogen use demand of each hydrogen use station. The hydrogen production unit in each hydrogen production group is connected to the hydrogen use station through the hydrogen output buffer equipment.
[0101] For example, the hydrogen use scenarios are the ammonia production scenario and the methanol production scenario. The hydrogen use demand of the ammonia production scenario is less than that of the methanol production scenario. The hydrogen production station has 50 hydrogen production units. The hydrogen production units can be divided into two groups according to the hydrogen use demand of the hydrogen use scenario. 20 hydrogen production units of the hydrogen production station are used as hydrogen production group 1 for the ammonia production scenario, and 30 hydrogen production units of the hydrogen production station are used as hydrogen production group 2 for the methanol production scenario.
[0102] The hydrogen production station control unit allocates the hydrogen production power of each hydrogen production group according to the hydrogen production plan of the ammonia production scenario and the methanol production scenario and the new energy input power. For example, the hydrogen production power of the hydrogen production group 1 is 40% of the new energy input power, and the hydrogen production power of the hydrogen production group 2 is 60% of the new energy input power. The hydrogen production station control unit controls each hydrogen production group to work according to the allocated hydrogen production power.
[0103] Optionally, the new energy input power can be allocated according to the priority of the hydrogen use station to meet the more urgent hydrogen use demand first.
[0104] Optionally, the new energy input power can be allocated according to the proportion of the hydrogen production unit, the proportion of the hydrogen production demand.
[0105] Figure 4 is a connection schematic diagram of the hydrogen production system and the hydrogen using station provided by the embodiment of the present application, as shown, Figure 4 The hydrogen production plan curve is input into the hydrogen production control unit, and the hydrogen production plan curve can be a curve with time as the horizontal axis and hydrogen production as the vertical axis, or can be converted into a curve with time as the horizontal axis and power as the vertical axis according to the efficiency curve of the hydrogen production station.
[0106] Optionally, if the new energy input power is greater than the hydrogen production plan demand power, hydrogen is output according to the hydrogen production plan demand, and if the hydrogen production station can accommodate the remaining new energy input power and the hydrogen output buffer device has storage space, the excess hydrogen is stored.
[0107] Optionally, if the new energy input power is greater than the hydrogen production station accommodation power, if (new energy input power-hydrogen production station accommodation power) < upper limit of the charging power of the electric energy storage device, the charging power of the electric energy storage device = (new energy input power-hydrogen production station accommodation power), if (new energy input power-hydrogen production station accommodation power) > upper limit of the charging power of the electric energy storage device, the charging power of the electric energy storage device = upper limit of the charging power of the electric energy storage device, at this time, the new energy input power is limited, and the new energy limit power = hydrogen production station accommodation power + upper limit of the charging power of the electric energy storage device.
[0108] If the hydrogen output buffer device has no storage space, the new energy limit power = hydrogen production plan demand power + upper limit of the charging power of the electric energy storage device, or the excess new energy power is input into the power grid.
[0109] Optionally, if the new energy power is less than the hydrogen production plan demand power, the discharge of the electric energy storage device or the supplement of hydrogen from the hydrogen storage device is considered, and if the upper limit of the electric energy storage device discharge power and the upper limit of the hydrogen output buffer device supplement are reached, the power grid can be powered down to maintain the hydrogen production plan.
[0110] In the above technical solution, according to the hydrogen using priority of each hydrogen using station, the hydrogen using demand of each hydrogen using station, and / or the proportion of the hydrogen production unit corresponding to each hydrogen using station, and the new energy input power, the hydrogen using control unit can divide the hydrogen production unit groups according to the number of hydrogen using scenarios, control the hydrogen production unit groups to work according to the allocated hydrogen production power, which is beneficial to efficient and flexible operation of the hydrogen production station, and improves the control freedom and practicability of the hydrogen production station.
[0111] In an embodiment of the present application, the method further comprises:
[0112] In a case where the first hydrogen production unit of the target hydrogen production group is cut out of the target hydrogen production group, the hydrogen production power of the target hydrogen production group is updated according to the other hydrogen production units remaining in the target hydrogen production group.
[0113] It is easily understood that, in a case where the first hydrogen production unit of the target hydrogen production group is cut out of the target hydrogen production group, the hydrogen production control unit updates the hydrogen production power of the target hydrogen production group according to the other hydrogen production units remaining in the target hydrogen production group.
[0114] For example, the hydrogen production control unit allocates the hydrogen production power to the hydrogen production group 1 and the hydrogen production group 2, and when the hydrogen production input power of the hydrogen production group 1 decreases, controls according to a preset hydrogen production unit switching strategy: if the first hydrogen production unit in the hydrogen production group 1 fails when operating, is cut out of the control sequence in a fault state, and the hydrogen production power is allocated among the remaining operable hydrogen production units.
[0115] If the first hydrogen production unit is restored from the fault state to the operable state, is set to the group after being put back into the corresponding control sequence to participate in operation, and participates in the allocation of the power.
[0116] Optionally, if a hydrogen production unit needs to be overhauled, the hydrogen production unit can be set to an independent operation mode and actively separated from the control sequence.
[0117] In the above technical solution, in a case where the first hydrogen production unit of the target hydrogen production group is cut out of the target hydrogen production group, the hydrogen production power of the target hydrogen production group is updated according to the other hydrogen production units remaining in the target hydrogen production group, which reduces the volatility of the hydrogen production station, improves the stability of the hydrogen production station, and is beneficial to efficient and flexible operation of the hydrogen production station.
[0118] In an embodiment of the present application, the method further comprises:
[0119] In the operation process of the hydrogen production system, if it is detected that the hydrogen consumption station is updated or the hydrogen consumption demand of the hydrogen consumption station changes, each hydrogen production unit in the hydrogen production station is re-divided according to the updated information of the hydrogen consumption station and the current hydrogen consumption demand of each hydrogen consumption station;
[0120] According to the hydrogen production groups obtained after re-dividing, the state of the valve between the hydrogen output end of each hydrogen production unit in each hydrogen production group obtained after re-dividing and the hydrogen output buffer device is set.
[0121] It is easy to understand that, in the operation process of the hydrogen production system, the number of hydrogen production units in different groups can be increased or reduced as the hydrogen use scene is updated or the hydrogen use demand is adjusted. If the hydrogen production station control unit detects that the hydrogen use station is updated or the hydrogen use demand of the hydrogen use station changes, the hydrogen production units in the hydrogen production station are re-divided according to the information of the updated hydrogen use station and the current hydrogen use demand of each hydrogen use station.
[0122] According to the hydrogen production groups obtained after re-division, the hydrogen production station control unit sets the state of the valve between the hydrogen output end of each hydrogen production unit in each hydrogen production group obtained after re-division and the hydrogen output buffer device, and allocates the hydrogen production power of each group of hydrogen production units according to the hydrogen production plan of the hydrogen use scene and the new energy input power.
[0123] Optionally, in the operation process, when the hydrogen use demand of a certain hydrogen use station changes, the hydrogen production station control unit can coordinate the hydrogen production units of other hydrogen use groups to switch to the hydrogen use station, and switch the hydrogen production units to the hydrogen use station by selecting the opening and closing of the valve.
[0124] In the above technical solution, the hydrogen production station control unit can switch the hydrogen production units according to the change of the hydrogen use demand of the hydrogen use station, realize the scheduling of the hydrogen production plan in the hydrogen production station, and is conducive to the efficient and flexible operation of the hydrogen production station, and improves the control freedom and practicability of the hydrogen production station.
