Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic hydrogen production, and in particular to a hydrogen energy supply and demand control system and method. Background Art

[0002] Hydrogen is known as the most promising clean energy in the 21st century due to its cleanliness, pollution-free and high heat output. With the development of science and technology, the application of hydrogen is becoming more and more extensive, which puts forward higher requirements for the supply and demand regulation of hydrogen.

[0003] In the field of hydrogen energy manufacturing, traditional hydrogen energy supply and demand regulation methods usually adopt a centralized management model. Each demander can log into the system to propose hydrogen production demands to its corresponding hydrogen production manufacturer. Then the hydrogen production manufacturer corresponding to the demander adjusts the hydrogen production capacity of each electrolyzer according to the demander's hydrogen production demand.

[0004] Since this method lacks intelligent control methods, the following problems arise: 1. It is difficult to fully utilize the electrolyzer clusters of different manufacturers, resulting in irrational resource allocation, waste of resources and low efficiency; 2. When the demander proposes a hydrogen production demand, the hydrogen manufacturer needs to manually adjust the hydrogen production capacity of each electrolyzer, which has problems such as slow response speed, inflexible adjustment and easy errors, and cannot meet the demander's immediate hydrogen demand; 3.

[0052] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0053] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0054] This embodiment provides a hydrogen energy supply and demand regulation method, which is implemented based on a hydrogen energy supply and demand regulation system. Figure 1A flow chart of a hydrogen energy supply and demand control method provided in an embodiment of the present invention, referring to Figure 1 As shown, the hydrogen energy supply and demand regulation method includes:

[0055] S110. Receive hydrogen demand from each demander in real time.

[0056] Figure 2 A structural block diagram of a hydrogen energy supply and demand control system provided by an embodiment of the present invention, referring to Figure 2 As shown, the hydrogen energy supply and demand control system includes multiple demand parties 1 and at least one hydrogen storage device 2, and each demand party 1 in the same area is connected to the same hydrogen storage device 2.

[0057] The demand side 1 may include but is not limited to corporate users and individual users with hydrogen demand, i.e., downstream users of hydrogen production plants. The same region may include but is not limited to the region within the same geographical scope or the region within the same administrative scope. This embodiment does not specifically limit this, as long as the distance between the hydrogen storage device 2 and the demand side 1 is short. It should be noted that multiple demand sides 1 may be located in the same region or in different regions. Figure 2 The hydrogen energy supply and demand regulation system is shown by way of example only to include 7 demand parties 1 located in two different regions, but the number and regions of the demand parties 1 are not limited. In other embodiments, the hydrogen energy supply and demand regulation system may also include 6 demand parties 1 located in one region or 9 demand parties 1 located in 4 different regions, etc.

[0058] When demander 1 has a demand for hydrogen, he may issue a hydrogen demand. In an optional embodiment, the hydrogen demand may include a required hydrogen flow rate and a hydrogen usage duration. For example, demander 1 may issue a hydrogen demand with a required hydrogen flow rate of 1000 Nm3 / h and a hydrogen usage duration of 30 days.

[0059] The hydrogen storage device 2 may include, but is not limited to, a hydrogen storage high-pressure steel cylinder or a metal oxide hydrogen storage alloy container, etc., for storing hydrogen. Each demander 1 in the same area is connected to the same hydrogen storage device 2, so that the hydrogen storage device 2 can transmit hydrogen to each demander 1 in the same area, which is beneficial to shorten the distance of hydrogen transmission, thereby saving costs and improving safety performance. In an optional embodiment, the hydrogen storage device 2 includes a hydrogen inlet and a hydrogen outlet, and each demander 1 in the same area is connected to the hydrogen outlet of the same hydrogen storage device 2 through a pipeline.

[0060] S120: When a hydrogen demand is received, an authentication security verification is performed on the party that issued the hydrogen demand.

[0061] Among them, the authentication security verification of the demander 1 who issues the hydrogen demand may include but is not limited to identity verification of the demander 1 who issues the hydrogen demand or the compliance of the hydrogen demand issued, so as to ensure that the hydrogen storage pool is only for the legitimate demander 1, and provides hydrogen when the hydrogen demand issued by the demander 1 is compliant, which is conducive to improving the security of hydrogen energy supply and demand regulation.

[0062] In an optional embodiment, based on the identity information of the demander 1 who issued the hydrogen demand, it is possible to search among all the identity information of the legitimate demanders 1 whether there is a demander 1 whose identity information is the same as that of the demander 1 who issued the hydrogen demand. If there is a legitimate demander 1 whose identity information is the same as that of the demander 1 who issued the hydrogen demand, it is determined that the demander 1 has passed the authentication security verification; on the contrary, if there is no legitimate demander 1 whose identity information is the same as that of the demander 1 who issued the hydrogen demand, it is determined that the demander 1 has not passed the authentication security verification.

[0063] S130: When the demander passes the authentication security verification, the hydrogen storage device in the area where the demander is located is controlled to transmit hydrogen to the demander according to the hydrogen demand.

[0064] Specifically, the hydrogen demand issued by each demander 1 is received in real time, and when the hydrogen demand is received, the demander 1 that issued the hydrogen demand is authenticated and securely verified to ensure the identity of the demander 1 and the compliance of the hydrogen demand. When the demander 1 passes the authentication and security verification, that is, the demander 1 is a legitimate demander 1, and the hydrogen demand issued by the demander 1 is compliant, the hydrogen storage device 2 in the area where the demander 1 is located is controlled to transmit a corresponding flow of hydrogen to the demander 1 according to the hydrogen demand, and the duration of the transmission flow is controlled.

[0065] It is understandable that the demander 1 may change the hydrogen use plan at any time due to its own reasons, for example, ending the hydrogen use demand ahead of schedule, etc. Therefore, in an optional embodiment, the hydrogen supply and demand regulation method also includes: receiving the demand to stop hydrogen use issued by the demander 1 in real time, and upon receiving the demand to stop hydrogen use, controlling the hydrogen storage device 2 to stop transmitting hydrogen to the demander 1, so as to promptly respond to the demand of the demander 1 to end the hydrogen use ahead of schedule, so as to avoid waste of hydrogen energy.

[0066] In this embodiment, by receiving the hydrogen demand issued by each demander in real time, and when receiving the hydrogen demand, the demander issuing the hydrogen demand is authenticated and verified, so that when the demander passes the authentication and verification, the hydrogen storage device in the area where the demander is located is controlled to transmit hydrogen to the demander according to the hydrogen demand, so that only the demander who passes the authentication and verification can use hydrogen, which can prevent the system from being attacked by malicious attacks and causing security problems, avoid possible security loopholes in user authentication, data transmission and pipeline control, etc., and is conducive to improving the security of hydrogen energy supply and demand regulation. In addition, according to the hydrogen demand, the hydrogen storage device in the area where the demander is located is controlled to transmit hydrogen to the demander, so that when the hydrogen flow rate in the hydrogen demand issued by the demander is small, the hydrogen storage device transmits a small flow of hydrogen to the demander, and when the hydrogen flow rate in the hydrogen demand issued by the demander is large, the hydrogen storage device transmits a large flow of hydrogen to the demander, so that the hydrogen produced by the electrolyzer clusters of each manufacturer can be reasonably distributed, which is conducive to improving the utilization rate of hydrogen energy and saving resources.

[0067] Figure 3 A flowchart of another hydrogen energy supply and demand control method provided by an embodiment of the present invention. Based on the above embodiment, this embodiment further explains in more detail how to perform authentication security verification and how to control the hydrogen storage device in the area where the demander is located to transmit hydrogen to the demander, and further defines the steps for determining the working status of each electrolyzer cluster when the demander passes the authentication security verification. Figure 3 As shown, the hydrogen energy supply and demand regulation method specifically includes:

[0068] S210: Receive hydrogen demand from each demander in real time.

[0069] S220. When receiving a hydrogen demand, determine whether the demander is in the target demander set; if so, execute S230; if not, execute S250.

[0070] The target demander set may include a pre-stored set of all legal demanders. By judging whether the demander 1 who issues the hydrogen demand is in the target demander set, it can be determined whether the demander 1 who issues the hydrogen demand is a legal demander.

[0071] S230, determining whether the hydrogen demand issued by the demander is within a preset demand range; if so, executing S240; if not, executing S250.

[0072] The preset demand range may be a compliant demand range of the demander 1, for example, the preset demand range may include but is not limited to a hydrogen flow range and a hydrogen usage time range, etc. It should be noted that the preset demand range of each demander 1 is determined according to a contract or agreement with the demander 1, and the preset demand ranges of different demanders 1 may be the same or different.

[0073] Specifically, by judging whether the hydrogen demand issued by the demander 1 is within a preset demand range, it can be determined whether the hydrogen demand issued by the demander 1 is compliant.

[0074] S240: Determine whether the demander has passed the authentication security verification.

[0075] S250: Determine that the demander has not passed the authentication security verification.

[0076] Specifically, by receiving the hydrogen demand issued by each demander 1 in real time, and when receiving the hydrogen demand, it is determined whether the demander 1 is in the target demander set. If the demander 1 is in the target demander set, it means that the demander 1 is a legitimate demander. Therefore, it is further determined whether the hydrogen demand issued by the demander 1 is within the preset demand range. If the hydrogen demand issued by the demander 1 is within the preset demand range, it means that the hydrogen demand is compliant. Therefore, it can be determined that the demander 1 has passed the authentication security verification, and the hydrogen storage pool can transmit hydrogen to the demander 1; on the contrary, if the demander 1 is not in the target demander set, it means that the demander 1 is not a legitimate demander, or the hydrogen demand issued by the demander 1 is not within the preset demand range, it means that the hydrogen demand is not compliant. Therefore, it can be determined that the demander 1 has not passed the authentication security verification, and the hydrogen storage pool does not transmit hydrogen to the demander 1.

[0077] In an optional embodiment, when the demander 1 fails the authentication security verification, a reminder of the authentication security verification failure is issued to remind the hydrogen energy supplier that there are safety hazards in the hydrogen energy supply and demand regulation, so that the hydrogen energy supplier can eliminate the safety hazards in time and further improve the safety of hydrogen energy supply and demand regulation.

[0078] S260. When the demander passes the authentication security verification, the region where the demander is located is obtained.

[0079] The hydrogen energy supply and demand control system further includes a plurality of electrolyzer clusters 3 , and each electrolyzer cluster 3 in the same area is connected to the same hydrogen storage device 2 through a pipeline.

[0080] The electrolyzer cluster 3 is used to prepare hydrogen, which may include but is not limited to electrolyzer clusters 3 of different types from different manufacturers, for example, including but not limited to PEM electrolyzer clusters, ALK electrolyzer clusters, solid oxide electrolyzer clusters, etc. Each electrolyzer cluster 3 includes at least one electrolyzer. It should be noted that multiple electrolyzer clusters 3 may be located in the same area or in different areas. Figure 2 It is only exemplified that the hydrogen energy supply and demand control system includes 5 electrolyzer clusters 3 located in two different areas, and the number and area of ​​the electrolyzer clusters 3 are not limited. In other embodiments, the hydrogen energy supply and demand control system may also include 6 electrolyzer clusters 3 located in one area or 9 electrolyzer clusters 3 located in 4 different areas. It can be understood that in one area, there may be a situation where there are fewer electrolyzer clusters 3 but more demanders 1, and in other areas, there may be a situation where there are more electrolyzer clusters 3 but fewer demanders 1. Therefore, there is no connection between the number of electrolyzer clusters 3 and the number of demanders 1 in the same area. This embodiment aims to regulate the supply and demand of hydrogen energy in each area.

[0081] Each electrolyzer cluster 3 in the same area is connected to the same hydrogen storage device 2 through a pipeline. In an optional embodiment, each electrolyzer cluster 3 in the same area is connected to the hydrogen inlet of the same hydrogen storage device 2 through a pipeline, so that the hydrogen prepared by each electrolyzer cluster 3 in the same area can be transmitted to the hydrogen storage device 2 for storage for use by the demanders 1 in the area, which is beneficial to the reasonable allocation of the hydrogen production capacity of each electrolyzer cluster 3 and improves resource utilization.

[0082] S270. Determine the working status of each electrolyzer cluster according to the region where the demander is located and the hydrogen demand.

[0083] The working status of the electrolyzer cluster 3 may include, but is not limited to, the current hydrogen production capacity of the electrolyzer cluster 3 .

[0084] Specifically, when the demander 1 who issues a hydrogen demand passes the authentication security verification, the working state of the control switch corresponding to the demander 1 is controlled according to the hydrogen demand, that is, the hydrogen flow passing through the control switch corresponding to the demander 1 is controlled to transmit a corresponding flow of hydrogen to the demander 1. At the same time, by obtaining the area where the demander 1 is located, the working state of each electrolyzer cluster 3 is determined according to the area where the demander 1 is located and the hydrogen demand, so that the corresponding electrolyzer cluster 3 increases the hydrogen production capacity corresponding to the hydrogen demand, thereby making the hydrogen amount in the hydrogen storage tank in the area constant, preventing the hydrogen amount in the hydrogen storage tank from being too small, making it difficult to respond to the hydrogen production demand of the demander 1 in time, or preventing the hydrogen amount in the hydrogen storage tank from being too large, affecting the safety performance of the hydrogen storage tank.

[0085] S280. According to the hydrogen demand, control the working state of the control switch corresponding to the demander.

[0086] Among them, continue to refer to Figure 2 As shown, the hydrogen energy supply and demand regulation system also includes a plurality of control switches 4 corresponding to each demander 1 , and each demander 1 is connected to the hydrogen storage device 2 via a pipeline via the corresponding control switch 4 .

[0087] The control switch 4 is used to control the connection or cutoff of the corresponding pipeline. In an optional embodiment, the control switch 4 may include a flow switch for controlling the flow of the corresponding pipeline and the connection or cutoff of the corresponding pipeline. Each demander 1 is connected to the pipeline of the hydrogen storage device 2 through the corresponding control switch 4, so that the control switch 4 can control the flow of hydrogen provided by the hydrogen storage device 2 to the corresponding demander 1.

[0088] The working state of the control switch 4 includes but is not limited to the control switch 4 being in the closed state, the control switch 4 being in the on state, etc. In an optional embodiment, the working state of the control switch 4 also includes the control switch 4 being in the on state and having different openings through the control switch 4. When the control switch 4 is in the closed state, the corresponding pipeline is cut off, and when the control switch 4 is in the on state, the corresponding pipeline is connected.

[0089] In this embodiment, when receiving the hydrogen demand, it is determined whether the demander is in the target demander set. If the demander is in the target demander set, it means that the demander is a legitimate demander. Therefore, it is further determined whether the hydrogen demand issued by the demander is within the preset demand range. If the hydrogen demand issued by the demander is within the preset demand range, it means that the hydrogen demand is compliant. Therefore, it can be determined that the demander has passed the authentication security verification, and the hydrogen storage pool can transmit hydrogen to the demander. On the contrary, if the demander is not in the target demander set, it means that the demander is not a legitimate demander, or the hydrogen demand issued by the demander is not within the preset demand range, which means that the hydrogen demand is not compliant. Therefore, it can be determined that the demander has not passed the authentication security verification, and the hydrogen storage pool does not transmit hydrogen to the demander, which is beneficial to improving the safety of hydrogen energy supply and demand regulation. In addition, when the demander passes the authentication security verification, the working state of the control switch corresponding to the demander is controlled according to the hydrogen demand, so as to transmit the corresponding flow of hydrogen to the demander. At the same time, the working state of each electrolyzer cluster is determined according to the region where the demander is located and the hydrogen demand, so that the corresponding electrolyzer cluster increases the hydrogen production capacity corresponding to the hydrogen demand, thereby making the amount of hydrogen in the hydrogen storage pool in the area constant, preventing the amount of hydrogen in the hydrogen storage pool from being too small, making it difficult to respond to the hydrogen production demand of the demander in time, or the amount of hydrogen in the hydrogen storage pool from being too large, affecting the safety performance of the hydrogen storage pool, which is conducive to ensuring the continuity of hydrogen supply and demand.

[0090] Figure 4A flowchart of another method for regulating hydrogen supply and demand provided in an embodiment of the present invention. Based on the above embodiment, this embodiment further defines how to control the working state of the control switch corresponding to the demander and the working state of each electrolyzer cluster according to the hydrogen demand, refer to Figure 4 As shown, the hydrogen energy supply and demand regulation method specifically includes:

[0091] S310, receiving hydrogen demand from each demander in real time.

[0092] S320: When a hydrogen demand is received, an authentication security verification is performed on the party that issued the hydrogen demand.

[0093] S330: When the demander passes the authentication security verification, the region where the demander is located is obtained.

[0094] S340. Obtain the remaining hydrogen production capacity of the electrolyzer cluster in the same area as the demand side.

[0095] The remaining hydrogen production capacity of the electrolyzer cluster 3 can be understood as the difference between the rated hydrogen production capacity of the electrolyzer cluster 3 and the current hydrogen production capacity of the electrolyzer cluster 3, that is, the hydrogen production capacity that the electrolyzer cluster 3 can still provide.

[0096] S350: Determine the working status of each electrolyzer cluster according to the remaining hydrogen production capacity and hydrogen demand.

[0097] In an optional embodiment, the hydrogen demand includes the hydrogen flow rate; the working state of each electrolyzer cluster 3 is determined according to the remaining hydrogen production capacity and the hydrogen demand, including: when the remaining hydrogen production capacity is greater than or equal to the hydrogen flow rate, the hydrogen flow rate is matched to the electrolyzer cluster 3 in the same area as the demander 1; when the remaining hydrogen production capacity is less than the hydrogen flow rate, return to execute S340 until the remaining hydrogen production capacity is greater than or equal to the hydrogen flow rate.

[0098] Specifically, by obtaining the remaining hydrogen production capacity of the electrolyzer cluster 3 in the same area as the demander 1, the working state of each electrolyzer cluster 3 is determined according to the remaining hydrogen production capacity and the hydrogen demand. Specifically, when the remaining hydrogen production capacity is greater than or equal to the hydrogen flow rate, the hydrogen flow rate is matched to the electrolyzer cluster 3 in the same area as the demander 1, so that the electrolyzer cluster 3 in the area increases the hydrogen production capacity corresponding to the hydrogen demand, thereby making the amount of hydrogen in the hydrogen storage tank in the area constant. On the contrary, when the remaining hydrogen production capacity is less than the hydrogen flow rate, it indicates that the hydrogen production capacity that can be provided by the electrolyzer cluster 3 in the area is less than the hydrogen flow rate. Therefore, the step of obtaining the remaining hydrogen production capacity of the electrolyzer cluster 3 in the same area as the demander 1 is returned until the remaining hydrogen production capacity is greater than or equal to the hydrogen flow rate, thereby making the amount of hydrogen in the hydrogen storage tank in the area constant, thereby preventing the amount of hydrogen in the hydrogen storage tank from being too small, making it difficult to respond to the hydrogen production demand of the demander 1 in time.

[0099] S360: Control the opening of the control switch corresponding to the demander according to the hydrogen consumption flow rate, and control the opening time and closing time of the control switch corresponding to the demander according to the hydrogen consumption time.

[0100] The hydrogen demand includes hydrogen flow and hydrogen duration. The hydrogen flow can be understood as the hydrogen flow required by demander 1, for example, 500 Nm3 / h or 1000 Nm3 / h. The hydrogen duration can be understood as the total duration that demander 1 needs hydrogen, for example, 50 days or 70 days.

[0101] It can be understood that the flow rate of hydrogen transmitted from the hydrogen storage tank to the corresponding demander 1 is different with different openings of the control switch 4. The smaller the opening of the control switch 4, the smaller the flow rate of hydrogen transmitted from the hydrogen storage tank to the corresponding demander 1. Correspondingly, the larger the opening of the control switch 4, the larger the flow rate of hydrogen transmitted from the hydrogen storage tank to the corresponding demander 1.

[0102] Specifically, when the demander 1 passes the authentication security verification, the opening of the switch 4 is controlled according to the hydrogen flow rate, so that the flow rate of hydrogen transmitted from the hydrogen storage tank to the corresponding demander 1 is equal to the hydrogen flow rate, and, according to the hydrogen usage time, the difference between the opening time and the closing time of the control switch 4 corresponding to the demander 1 is controlled to be equal to the hydrogen usage time.

If the demand party 1 fails the authentication and security verification, a reminder of the failure of the authentication and security verification is issued. If the demand party 1 passes the authentication and security verification, the authentication and security verification unit 51 sends the hydrogen demand of the demand party 1 to the hydrogen production attribution query unit 52. When the hydrogen production attribution query unit 52 receives the hydrogen demand of the demand party 1, it determines the area where the demand party 1 is located, and sends the hydrogen demand to the demand allocation unit 53 in the area where the demand party 1 is located.
