Description

Technical Field

[0001] This application relates to the field of hydrogen production, and in particular to a method, apparatus, and system for load distribution in a hydrogen production system. Background Technology

[0002] Hydrogen energy is a long-cycle, cross-seasonal energy storage resource. my country is vigorously developing hydrogen energy, with numerous wind, solar, and hydrogen production projects emerging. These projects typically combine alkaline water electrolysis and proton exchange membrane (PEM) water electrolysis. Due to differences in power, output, and other hydrogen production parameters and performance between these two types of equipment, hydrogen production stations need to address the load matching issue between the wind / solar power generation side and the hydrogen production side.

[0003] To address the load matching issue between wind and solar power generation and hydrogen production, a common approach is to activate a corresponding number of hydrogen production units based on the power generation data provided by wind and solar power plants. However, fluctuations in power generation data lead to frequent start-ups and shutdowns of the hydrogen production units, causing damage and hindering the efficient operation of the hydrogen production system. Summary of the Invention

[0004] This application provides a method, apparatus, and system for load distribution in a hydrogen production system, which at least solves the problem in the related art that frequent start-ups and shutdowns of hydrogen production equipment can cause damage to the equipment, resulting in the inefficient operation of the hydrogen production system.

[0005] In a first aspect, embodiments of this application provide a method, apparatus, and system for load allocation in a hydrogen production system, including:

[0006] For any hydrogen production equipment, obtain the upper limit and lower limit of the load power of the hydrogen production equipment, and the function of hydrogen production power with respect to hydrogen production efficiency. Based on the function, obtain the lower limit of hydrogen production efficiency corresponding to the upper limit of hydrogen production efficiency and the lower limit of load power.

[0007] All hydrogen production equipment is divided into several scheme libraries in a sequentially decreasing manner according to the number of equipment, and the minimum load power of hydrogen production equipment in the scheme libraries increases sequentially.

[0008] In any given scheme library, between the upper limit and the lower limit of hydrogen production efficiency, the hydrogen production efficiency of different hydrogen production equipment is configured to form several allocation schemes. The total input power of each allocation scheme and the target scheme under the same total input power are determined.

[0009] The solution database is searched in descending order of the number of hydrogen production equipment until the total input power that matches the input power of the hydrogen production system is determined. The hydrogen production equipment is then started according to the target solution corresponding to the determined total input power.

[0010] In one embodiment, several allocation schemes are formed by configuring different hydrogen production equipment between the upper limit and the lower limit of hydrogen production efficiency, including:

[0011] For the hydrogen production equipment in the scheme library, the efficiency of the hydrogen production equipment is configured in order of increasing upper limit of hydrogen production efficiency, and hydrogen production equipment with different efficiencies are combined to form several allocation schemes.

[0012] In one embodiment, determining the total input power of each allocation scheme and the target scheme under the same total input power includes:

[0013] In any allocation scheme, obtain the hydrogen production efficiency of each hydrogen production device in the allocation scheme, determine the input power of each hydrogen production device based on the hydrogen production efficiency, and obtain the hydrogen production power of each hydrogen production device according to the function.

[0014] The total input power and overall efficiency of the allocation scheme are determined based on the input power and hydrogen production efficiency.

[0015] Based on the total input power, several target schemes are determined. If there are allocation schemes with the same total input power among all allocation schemes, the allocation scheme with the best overall efficiency is taken as the target scheme. The target scheme includes the mapping relationship between overall efficiency, total input power and the power of each hydrogen production device.

[0016] In one embodiment, the overall efficiency satisfies the following formula:

[0017]

[0018] Where, η 整体s For the overall efficiency of s hydrogen production devices, P i Let η be the input power of the i-th hydrogen production device. i Let be the hydrogen production efficiency of the i-th hydrogen production device.

[0019] In one embodiment, obtaining the upper and lower limits of the load power of the hydrogen production equipment, and the hydrogen production power as a function of the hydrogen production efficiency, includes:

[0020] Based on the operational tests of the hydrogen production equipment, the upper and lower limits of the load power of the hydrogen production equipment, as well as the hydrogen production efficiency and hydrogen production power, are obtained, and the characteristic curve of hydrogen production power with respect to hydrogen production efficiency is obtained.

[0021] Based on the characteristic curves, a function of hydrogen production power with respect to hydrogen production efficiency is fitted; the function satisfies the following configuration:

[0022] P i =f(η i ),

[0023] Among them, P iη is the input power of hydrogen production equipment i. i Let f be the hydrogen production efficiency of hydrogen production equipment i, and let f be a function mapping relationship.

[0024] Secondly, embodiments of this application provide a load distribution device for a hydrogen production system, characterized in that it includes:

[0025] The module is used to obtain, for any hydrogen production equipment, the upper limit and lower limit of the load power of the hydrogen production equipment, and the function of hydrogen production power with respect to hydrogen production efficiency, and to obtain the lower limit of hydrogen production efficiency corresponding to the upper limit of hydrogen production efficiency and the lower limit of load power.

[0026] The partitioning module is used to divide all hydrogen production equipment into several scheme libraries in a sequentially decreasing manner, and the minimum load power of hydrogen production equipment in the scheme libraries increases sequentially.

[0027] The determination module is used to configure the hydrogen production efficiency of different hydrogen production equipment in any scheme library between the upper limit and the lower limit of hydrogen production efficiency to form several allocation schemes, determine the total input power of each allocation scheme, and the target scheme under the same total input power;

[0028] The startup module is used to query the solution library in descending order of the number of hydrogen production devices until the total input power that is the same as the input power of the hydrogen production system is determined, and then start the hydrogen production device according to the target solution corresponding to the determined total input power.

[0029] Thirdly, embodiments of this application provide a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the hydrogen production system load allocation method as described in the first aspect above.

[0030] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the hydrogen production system load allocation method as described in the first aspect above.

[0031] The hydrogen production system load allocation method, apparatus, and system provided in this application have at least the following technical effects.

[0032] For any hydrogen production equipment, obtain the upper and lower limits of its load power, as well as the function of hydrogen production power with respect to hydrogen production efficiency. Based on this function, determine the lower limit of hydrogen production efficiency corresponding to the upper and lower load power limits. Divide all hydrogen production equipment into several scheme libraries in descending order of equipment number, with the minimum load power lower limit of hydrogen production equipment in each scheme library increasing sequentially. Within any scheme library, configure different hydrogen production efficiencies for different hydrogen production equipment between the upper and lower limits of their respective efficiency limits to form several allocation schemes. Determine the total input power for each allocation scheme and the target scheme under the same total input power. Search the scheme library in descending order of the number of hydrogen production equipment until a total input power matching the input power of the hydrogen production system is determined. Start the hydrogen production equipment according to the target scheme corresponding to the total input power.

[0033] In this manner, the hydrogen production system queries the solution library in descending order of the number of devices, identifies the total input power that matches the system's input power, and then activates the hydrogen production equipment based on the target solution corresponding to that total input power. This process prioritizes the allocation of solutions with a larger number of hydrogen production devices, maximizing the utilization of these devices according to the actual application scenario. Compared to existing technologies that rely on input power to directly activate hydrogen production equipment, this reduces frequent start-ups and shutdowns, thereby improving the system's operational efficiency.

[0047] Hydrogen production systems typically consist of a combination of alkaline water electrolysis and proton exchange membrane water electrolysis equipment, or either separately. The electricity sources for these systems include wind power, solar power, and grid power.

[0048] Firstly, embodiments of this application provide a method for load allocation in a hydrogen production system. Figure 1 This is a flowchart illustrating a load allocation method for a hydrogen production system according to an exemplary embodiment, such as... Figure 1 As shown, the load allocation method for the hydrogen production system includes:

[0049] Step S101: For any hydrogen production equipment, obtain the upper limit and lower limit of the load power of the hydrogen production equipment, and the function of hydrogen production power with respect to hydrogen production efficiency. Based on the function, obtain the lower limit of hydrogen production efficiency corresponding to the upper limit of hydrogen production efficiency and the lower limit of load power.

[0050] Based on the load test of the hydrogen production equipment, the upper and lower limits of the load power of the hydrogen production equipment, as well as the hydrogen production efficiency and hydrogen production power, are obtained, and the characteristic curve of hydrogen production power with respect to hydrogen production efficiency is obtained.

[0051] All hydrogen production equipment underwent operational load testing to obtain the upper and lower limits of the safe operating load power for each unit. Variable operating condition testing was also conducted on all hydrogen production equipment to obtain the hydrogen production efficiency and power output. Based on the obtained hydrogen production efficiency and power output, a characteristic curve of hydrogen production power versus hydrogen production efficiency was obtained.

[0052] In one embodiment, Figure 2 This is a flowchart illustrating the characteristic curve of obtaining hydrogen power versus hydrogen production efficiency according to an exemplary embodiment, such as... Figure 2 As shown, based on the hydrogen production method and the specifications of the hydrogen production equipment, load limit and load lower limit tests were conducted to determine the upper and lower load limits for safe operation of the hydrogen production equipment. Within the range of the upper and lower load limits, variable operating condition tests were conducted to obtain the characteristic curve of hydrogen production power versus hydrogen production efficiency.

[0053] In one embodiment, the hydrogen production system includes several alkaline water electrolysis hydrogen production devices and several proton exchange membrane water electrolysis hydrogen production devices. The lower limit of the safe operating load power for each hydrogen production device is obtained through hydrogen load testing. Optionally, the lower limit of the load power for each hydrogen production device includes P. ALK1 Lower limit, P ALK2 Lower limit, ..., P ALKM Lower limit, P PEM1 Lower limit, P PEM2 Lower limit, ..., P PEMN Lower limit.

[0054] Based on the characteristic curves, a function of hydrogen production power with respect to hydrogen production efficiency is fitted. The function satisfies the following configuration:

[0055] P i =f(η i ),

[0056] Among them, P i η is the input power of hydrogen production equipment i. i Let f be the hydrogen production efficiency of hydrogen production equipment i, and let f be a function mapping relationship.

[0057] Based on the function of hydrogen production power with respect to hydrogen production efficiency, the upper limit of hydrogen production efficiency and the optimal hydrogen production power corresponding to the upper limit of hydrogen production efficiency are determined, as well as the lower limit of hydrogen production efficiency corresponding to the lower limit of hydrogen production equipment load power. Based on the determined upper and lower limits of hydrogen production efficiency, and using a preset efficiency variation step size, the hydrogen production power at different hydrogen production efficiencies is determined to establish a mapping relationship between hydrogen production efficiency and hydrogen production power. For example, if the preset efficiency variation step size is 5%, the upper limit of hydrogen production efficiency is η1, and the lower limit of hydrogen production efficiency is η2, then the hydrogen production power corresponding to each hydrogen production efficiency among 95%η1, 90%η1, ..., η2 is determined to establish a mapping relationship between hydrogen production efficiency and hydrogen production power.

[0058] In one embodiment, Figure 3 This is a flowchart illustrating the mapping relationship between hydrogen production efficiency and hydrogen production power according to an exemplary embodiment. Figure 3 As shown, based on the characteristic curve of hydrogen production power with respect to hydrogen production efficiency, and the function of hydrogen production power with respect to hydrogen production efficiency, the hydrogen production power corresponding to the highest hydrogen production efficiency and the hydrogen production efficiency corresponding to the lower limit of load power are determined according to the function. Based on this, the hydrogen production power corresponding to different proportions of the highest hydrogen production efficiency is determined and the corresponding range of hydrogen production power is obtained.

[0059] Based on the testing of the hydrogen production equipment, the lower limit of load power, hydrogen production efficiency, and hydrogen production power were obtained, thereby obtaining the characteristic curve of the hydrogen production equipment, which laid the foundation for subsequent allocation based on the operating characteristics of the hydrogen production equipment.

[0060] Step S102: Divide all hydrogen production equipment into several scheme libraries in a sequentially decreasing manner according to the number of equipment, and the minimum load power of hydrogen production equipment in the several scheme libraries increases sequentially.

[0061] All hydrogen production equipment was sorted according to its minimum load power limit from smallest to largest, and the equipment with the smallest minimum load power limit was removed sequentially, thus dividing all hydrogen production equipment into several scheme libraries. The number of hydrogen production equipment in each scheme library was different, and the minimum load power of the hydrogen production equipment in each scheme library increased sequentially.

[0062] In one embodiment, the hydrogen production system has M alkaline water electrolysis hydrogen production devices and N proton exchange membrane water electrolysis hydrogen production devices, resulting in a total of M+N hydrogen production devices. These M+N devices form the first solution library. Removing the hydrogen production device with the lowest load power limit from the M+N devices leaves M+N-1 hydrogen production devices, forming the second solution library. Removing the hydrogen production device with the lowest load power limit from the M+N-1 devices leaves M+N-2 hydrogen production devices, forming the third solution library. This process continues by removing hydrogen production devices with the lowest load power limits until M+N solution libraries are formed.

[0063] Based on the number of hydrogen production units included in the hydrogen production system, the hydrogen production units with the lowest minimum load power are removed sequentially, thus ensuring that high-power hydrogen production units are retained in the solution pool. By fully utilizing high-power hydrogen production units, more hydrogen is produced within the same time frame compared to low-power units, thereby improving the hydrogen production efficiency of the system.

[0064] Step S103: In any scheme library, between the upper limit and the lower limit of hydrogen production efficiency, configure the hydrogen production efficiency of different hydrogen production equipment to form several allocation schemes, determine the total input power of each allocation scheme, and the target scheme under the same total input power.

[0065] In any given scheme library, all hydrogen production equipment is sorted in ascending order of its hydrogen production efficiency upper limit. Starting with the hydrogen production equipment with the lowest hydrogen production efficiency upper limit, the hydrogen production efficiency of each equipment is configured sequentially, ensuring that the configured hydrogen production efficiency does not exceed the range of the upper and lower limits of the hydrogen production efficiency. This process is repeated until all hydrogen production equipment and hydrogen production efficiency in the scheme library are combined to form several allocation schemes.

[0066] In one embodiment, a solution library contains three hydrogen production devices. These devices are ordered in ascending order of their hydrogen production efficiency upper limits to obtain a first, second, and third hydrogen production device. If the preset efficiency variation step size is 5%, the upper limit of hydrogen production efficiency is η1, and the lower limit is η2, then the first hydrogen production device (95% η1), the second hydrogen production device (η1), and the third hydrogen production device (η1) form a first allocation scheme; the first hydrogen production device (90% η1), the second hydrogen production device (η1), and the third hydrogen production device (η1) form a second hydrogen production scheme; and so on, until the first hydrogen production device (η2), the second hydrogen production device (95% η1), and the third hydrogen production device (η1) form the Nth allocation scheme, and so on, until three hydrogen production devices with different hydrogen production efficiencies are combined to form several allocation schemes.

[0067] In any allocation scheme, the hydrogen production efficiency of each hydrogen production device in the allocation scheme is obtained. Based on the hydrogen production efficiency, the input power of each hydrogen production device is determined, and the hydrogen production power of each hydrogen production device is obtained according to the function.

[0068] In any allocation scheme, based on the hydrogen production efficiency of each hydrogen production device, the input power of the hydrogen production device at each hydrogen production efficiency is determined, and the hydrogen production power at each hydrogen production efficiency in the allocation scheme is determined according to the function of hydrogen production efficiency with respect to hydrogen production power.

[0069] Based on the input power and hydrogen production efficiency, the total input power and overall efficiency of the allocation scheme are determined. The overall efficiency satisfies the following formula:

[0070]

[0071] Where, η 整体s For the overall efficiency of s hydrogen production devices, P i Let η be the input power of the i-th hydrogen production device. i Let be the hydrogen production efficiency of the i-th hydrogen production device.

[0072] Based on the total input power, a target scheme corresponding to each total input power is determined. If there are allocation schemes with the same total input power among all allocation schemes, then the allocation scheme with the best overall efficiency among these allocation schemes with the same total power is taken as the target scheme. The target scheme includes the mapping relationship between overall efficiency, total input power, and the power of each hydrogen production device.

[0073] Each solution library includes allocation schemes for combinations of hydrogen production equipment with different efficiencies, covering all possible power situations of the hydrogen production equipment during operation. This ensures that there is a corresponding allocation scheme based on the input power of the hydrogen production system, and that the hydrogen production equipment can operate according to the application scenario.

[0074] Step S104: Search the solution library in descending order of the number of hydrogen production equipment until the total input power that is the same as the input power of the hydrogen production system is determined, and start the hydrogen production equipment according to the target solution corresponding to the determined total input power.

[0075] The input power of the hydrogen production system is obtained by searching the solution library in descending order of the number of hydrogen production devices. The input power of the hydrogen production system comes from the output power of power plants in wind power, photovoltaic power, and grid power. Since the solution library is formed by continuously reducing the number of hydrogen production devices with the lowest load power limit, it starts by searching the solution library that includes all hydrogen production devices. Prioritizing the solution library with the largest number of hydrogen production devices, the system searches for the total input power that matches the input power of the hydrogen production system. If the solution library with all hydrogen production devices matches the total input power of the hydrogen production system, then according to the mapping relationship between the overall efficiency, total input power, and power of each hydrogen production device in the target solution corresponding to the total input power, the corresponding hydrogen production device is activated and adjusted to the corresponding power. The activated hydrogen production devices correspond to different hydrogen production efficiencies.

[0076] In one embodiment, the hydrogen production system has M alkaline water electrolysis hydrogen production devices and N proton exchange membrane water electrolysis hydrogen production devices, resulting in a total of M+N hydrogen production devices. A first scheme library contains M+N hydrogen production devices and several first allocation schemes formed by combinations of these devices. A second scheme library contains M+N-1 hydrogen production devices and several second allocation schemes formed by combinations of these devices, and so on, until a M+Nth scheme library contains 1 hydrogen production device and several M+Nth allocation schemes formed by combinations of this device. After obtaining the input power of the hydrogen production system, a search is first performed in the first scheme library to obtain a total input power identical to the system's input power, and a corresponding first allocation scheme is determined based on this total input power. If no total input power identical to the system's input power is found in the first scheme library, the search proceeds to the second scheme library. If a total input power identical to the system's input power is found, a corresponding second allocation scheme is determined based on this total input power. This process continues until a total input power identical to the system's input power is found.

[0077] It should be noted that since the allocation schemes in the entire scheme library cover all possibilities in the operation of the hydrogen production equipment, if no total input power matching the input power of the hydrogen production system is found in the entire scheme library, it indicates that there is an equipment fault in the entire hydrogen production system, and the equipment needs to be repaired so that the hydrogen production system can continue to operate.

[0078] In another embodiment, Figure 4 This is a flowchart illustrating the process of searching for a corresponding allocation scheme in a scheme library, as shown in another exemplary embodiment. Figure 4 As shown, if the input power is greater than or equal to the sum of the lower limits of the load power of all hydrogen production equipment, the system searches in scheme library 1 (i.e., the scheme library with all hydrogen production equipment) for the load allocation scheme with the highest overall hydrogen production efficiency at that input power. If the input power is less than or equal to the sum of the lower limits of the load power of all hydrogen production equipment, the system prioritizes searching in scheme library 2 (i.e., the scheme library with one less hydrogen production equipment than the scheme library 1) for the load allocation scheme with the highest overall hydrogen production efficiency at that input power. This process is repeated in different scheme libraries until a suitable allocation scheme is found.

[0079] In one embodiment, Figure 5 This is a flowchart illustrating a load allocation method for a hydrogen production system according to another exemplary embodiment, such as... Figure 5 As shown, the hydrogen production equipment determines its corresponding power allocation method based on its respective operating characteristics. The power allocation scheme is determined based on the input power of the hydrogen production system, and the power of each hydrogen production unit is adjusted according to the power allocation scheme.

[0080] In summary, the hydrogen production system load allocation method provided in this application determines a scheme library based on the number of hydrogen production devices, includes schemes covering possible operating conditions of these devices, and prioritizes obtaining corresponding allocation schemes from the entire hydrogen production device scheme library based on the hydrogen input power. Then, it sequentially searches for corresponding allocation schemes based on the number of hydrogen production devices and starts the corresponding hydrogen production devices according to the found allocation schemes. This ensures that all hydrogen production devices in the entire hydrogen production system are kept running, reducing frequent start-ups and shutdowns, thus minimizing damage to the devices and ensuring reliable operation. Furthermore, the scheme library includes different numbers of hydrogen production devices, with each scheme library progressively reducing the number of devices with the lowest load limit, ensuring that the hydrogen production power of the devices in the scheme library is high, producing more hydrogen. The allocation schemes in the scheme library are determined based on the operating characteristics of different hydrogen production methods and specifications of the devices. After determining the allocation scheme based on the input power, starting the corresponding hydrogen production device allows it to operate based on its respective operating characteristics, thereby improving the operating efficiency of the hydrogen production system.

[0081] Secondly, embodiments of this application provide a load distribution device for a hydrogen production system. Figure 6 This is a block diagram illustrating a load distribution device for a hydrogen production system according to an exemplary embodiment. Figure 6 As shown, the hydrogen production system load allocation device includes: an acquisition module, used to obtain, for any one of the hydrogen production devices, the upper limit of the load power and the lower limit of the load power of the hydrogen production device, and the function of hydrogen production power with respect to hydrogen production efficiency, and to obtain the lower limit of hydrogen production efficiency corresponding to the upper limit of hydrogen production efficiency and the lower limit of the load power based on the function;

[0082] The partitioning module is used to divide all hydrogen production equipment into several scheme libraries in a sequentially decreasing manner, and the minimum load power lower limit of the hydrogen production equipment in the several scheme libraries increases sequentially.

[0083] The determination module is used to configure the hydrogen production efficiency of different hydrogen production devices to form several allocation schemes between the upper limit of hydrogen production efficiency and the lower limit of hydrogen production efficiency in any of the schemes library, and to determine the total input power of each allocation scheme and the target scheme under the same total input power.

[0084] The startup module is used to query the scheme library in descending order of the number of hydrogen production devices until the total input power that is the same as the input power of the hydrogen production system is determined, and then start the hydrogen production device according to the target scheme corresponding to the determined total input power.

[0085] In summary, the hydrogen production system load allocation device provided in this application, for any hydrogen production equipment, obtains the upper and lower limits of the load power of the equipment, as well as the function of hydrogen production power with respect to hydrogen production efficiency. Based on this function, it obtains the lower limit of hydrogen production efficiency corresponding to the upper and lower limits of the load power. All hydrogen production equipment is divided into several scheme libraries in descending order of the number of equipment, with the minimum load power lower limit of the hydrogen production equipment in each scheme library increasing sequentially. Within any scheme library, and between the upper and lower limits of the hydrogen production efficiency of the equipment, different hydrogen production efficiencies are configured to form several allocation schemes. The total input power of each allocation scheme and the target scheme under the same total input power are determined. The scheme library is queried in descending order of the number of hydrogen production equipment until a total input power matching the input power of the hydrogen production system is determined. Based on the target scheme corresponding to the total input power, the hydrogen production equipment is started.
