[0043] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0044] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0045] First, the application scenario of this disclosure is explained. This disclosure is applied to the scenario of hydrogen production. In the existing controlled hydrogen production method, the total hydrogen production power is distributed to the multiple electrolyzers in a preset order according to the maximum safe hydrogen production power.

[0046] However, the inventors discovered that the hydrogen production efficiency of the electrolyzer decreases as the hydrogen production power increases after the electrolyzer reaches its minimum safe power. Therefore, this leads to the problem that the hydrogen production efficiency of the electrolyzer is lower when producing hydrogen at its maximum safe power than when producing hydrogen at its minimum safe power, resulting in lower energy utilization efficiency.

[0047] Therefore, to solve the above problems, this disclosure provides a method, apparatus, storage medium, and electronic device for controlling hydrogen production. The method includes: determining one or more target electrolyzers from a plurality of electrolyzers based on a total hydrogen production power and a minimum safe power of each electrolyzer in a pre-set plurality of electrolyzers; allocating the total hydrogen production power to the one or more target electrolyzers according to a first preset power allocation method; the first preset power allocation method includes allocating power to the one or more target electrolyzers according to the minimum safe power of the one or more target electrolyzers; obtaining the remaining hydrogen production power after the total hydrogen production power is allocated according to the first preset power allocation method; allocating the remaining hydrogen production power to the one or more target electrolyzers according to a second preset power allocation method, the second preset power allocation method including allocating the remaining hydrogen production power to the one or more target electrolyzers according to a power efficiency curve, the power efficiency curve representing the ratio of hydrogen production power to hydrogen production efficiency of the electrolyzer; and controlling the one or more target electrolyzers to produce hydrogen according to the hydrogen production power allocated to the one or more target electrolyzers. In this way, by prioritizing the hydrogen production control method that meets the minimum safe power of the electrolyzer, it is beneficial to improve the hydrogen production efficiency of the electrolyzer. The remaining hydrogen production power is then allocated according to the power efficiency curve of the electrolyzer, enabling the electrolyzer to produce more hydrogen with the same energy consumption, thereby improving energy utilization efficiency.

[0048] The present disclosure will now be described in conjunction with specific embodiments.

[0049] Figure 1 This application illustrates a controlled hydrogen production method according to an exemplary embodiment, such as... Figure 1 As shown, the method includes:

[0050] S101. Based on the total hydrogen production power and the minimum safe power of each of the multiple electrolyzers pre-set, determine one or more target electrolyzers from the multiple electrolyzers.

[0051] The total hydrogen production power represents the total power required to produce hydrogen, and the minimum safe power represents the minimum hydrogen production power at which the electrolyzer can operate safely. The electrolyzer is prohibited from producing hydrogen at an operating power lower than the minimum safe power corresponding to the electrolyzer.

[0052] In one possible implementation, the hydrogen production power can be allocated according to the first preset power allocation method based on the total hydrogen production power and the minimum safe power of each of the plurality of electrolyzers to obtain one or more allocation schemes; the remaining hydrogen production power corresponding to the one or more allocation schemes can be obtained respectively; the target allocation scheme corresponding to the minimum remaining hydrogen production power among the one or more allocation schemes can be determined; and one or more electrolyzers corresponding to the target allocation scheme can be determined as target electrolyzers.

[0053] For example, a hydrogen production system may have three hydrogen production units, each corresponding to one electrolyzer. The basic parameters of these three electrolyzers are shown in Table 1 below:

[0054]

[0055] Table 1

[0056] As shown in Table 1 above, the minimum safe power of electrolytic cell A is 0.625MW, the minimum safe power of electrolytic cell B is 0.425MW, and the minimum safe power of electrolytic cell C is 0.45MW.

[0057] Assuming the total hydrogen production capacity is 1.3MW, based on the minimum safe power of the three electrolyzers and the first preset power allocation method, there are three allocation schemes: Scheme 1: Allocate the total hydrogen production capacity to electrolyzers A and B; Scheme 2: Allocate the total hydrogen production capacity to electrolyzers B and C; Scheme 3: Allocate the total hydrogen production capacity to electrolyzers A and C. The remaining hydrogen production capacity corresponding to these three allocation schemes are: Scheme 1: 1.3 - (0.625 + 0.425) = 0.25MW; Scheme 2: 1.3 - (0.425 + 0.45) = 0.425MW; Scheme 3: 1.3 - (0.625 + 0.45) = 0.225MW.

[0058] Based on the remaining hydrogen production power corresponding to the above three allocation schemes, it can be determined that Scheme 3 has the smallest remaining hydrogen production power. Therefore, Scheme 3 is determined as the target allocation scheme, and the electrolyzers A and C corresponding to Scheme 3 are determined as the target electrolyzers.

[0059] In this way, by determining the target electrolyzer corresponding to the allocation scheme with the minimum remaining hydrogen production power among multiple allocation schemes, it is beneficial to reduce the allocation of the remaining hydrogen production power, reduce the hydrogen production power of the target electrolyzer after reaching the minimum safe power, and improve the hydrogen production efficiency of the target electrolyzer.

[0060] S102. Distribute the total hydrogen production power to the one or more target electrolyzers according to the first preset power distribution method.

[0061] The first preset power allocation method includes allocating power to the one or more target electrolytic cells according to the minimum safe power of the one or more target electrolytic cells.

[0062] In this step, as described in step S101 above, after determining the target electrolyzer, the total hydrogen production power is allocated to the target electrolyzer according to the first preset power allocation method.

[0063] It should be noted that, since the electrolyzer is prohibited from producing hydrogen at an operating power lower than the minimum safe power corresponding to the electrolyzer, when the total hydrogen production power is less than the minimum safe power of each of the multiple electrolyzers, the multiple electrolyzers are controlled to stop producing hydrogen. In addition, the electrolyzer is also prohibited from producing hydrogen at an operating power higher than the maximum safe power corresponding to the electrolyzer, so when the total hydrogen production power is greater than the sum of the maximum safe power of the multiple electrolyzers, the multiple electrolyzers are controlled to produce hydrogen at the maximum safe power.

[0064] In this way, the total hydrogen production power is allocated to the target electrolyzer according to the first preset power allocation method, which is conducive to improving the hydrogen production efficiency of the target electrolyzer and improving energy utilization efficiency. In addition, it also limits the range of hydrogen production power of the target electrolyzer, which is conducive to ensuring safe production.

[0065] S103. Obtain the remaining hydrogen production power after the total hydrogen production power is allocated according to the first preset power allocation method.

[0066] In this step, as described in step S101 above, after the total hydrogen production power is allocated to the target electrolyzer according to the first preset power allocation method, the minimum safe power of the target electrolyzer is subtracted from the total hydrogen production power to obtain the remaining hydrogen production power.

[0067] S104. Allocate the remaining hydrogen production power to the one or more target electrolyzers according to the second preset power allocation method.

[0068] The second preset power allocation method includes allocating the remaining hydrogen production power to the one or more target electrolyzers according to the power efficiency curve, wherein the power efficiency curve characterizes the ratio of the hydrogen production power to the hydrogen production efficiency of the electrolyzer.

[0069] In this step, the first step is to obtain the power efficiency curve corresponding to the target electrolyzer, which can be obtained from the historical hydrogen production data records of the target electrolyzer.

[0070] For example, Figure 2 The power efficiency curve of electrolytic cell A in Table 1 is obtained from... Figure 2 It can be seen that the linear first-order polynomial fitting formula for electrolytic cell A is:

[0071]

[0072] in, Characterize the hydrogen production efficiency of electrolyzer A. and Let be the fitting parameters of the fitting formula, where This characterizes the theoretical hydrogen production efficiency of electrolyzer A under zero power conditions. The ratio representing the change in hydrogen production efficiency to the change in hydrogen production power of electrolyzer A is... Characterizing the power of the electrolyzer for water electrolysis, This characterizes the rated power of the electrolytic cell.

[0073] In actual hydrogen production, the electrolyzer is not producing hydrogen. The hydrogen production equipment containing the electrolyzer also incurs other non-hydrogen-producing energy consumption, such as insulation energy consumption. Taking insulation energy consumption as an example, under the condition that the electrolyte temperature and ambient temperature remain constant, the insulation energy consumption of the hydrogen production equipment is approximately constant. For instance, if the surface temperature of the hydrogen production equipment is 60℃ and the ambient temperature is 25℃, the insulation energy consumption of the hydrogen production equipment containing electrolyzer A is 32.96KW.

[0074] It should be noted that when the electrolyzer is in hydrogen production mode, the energy consumption of the hydrogen production equipment to which the electrolyzer is located is the hydrogen production energy consumption.

[0075] The power control of the hydrogen production system adopts an efficiency optimization control strategy, specifically:

[0076] The goal is to find multiple hydrogen production devices in the hydrogen production system that achieve low-energy hydrogen production, minimizing the overall energy consumption of the system. The energy consumption calculation formula for this hydrogen production system is as follows:

[0077]

[0078] Among them, the The energy consumption of this hydrogen production system is represented by T and N, respectively, representing the hydrogen production period and the total number of target electrolyzers. , These represent the hydrogen production energy consumption and non-hydrogen production energy consumption of unit i during time period t, respectively.

[0079] Therefore, when all of these electrolyzers are in a non-hydrogen-producing state, only In this case, some of the multiple electrolyzers produce hydrogen, while others do not. , Item, when all of the multiple electrolyzers produce hydrogen, only item.

[0080] Therefore, the hydrogen production energy consumption of this hydrogen production equipment can be obtained according to the linear first-order polynomial fitting formula of the electrolyzer A mentioned above:

[0081]

[0082] in, The state of the hydrogen electrolyzer is a 0-1 variable. =1 and =0 indicates that electrolytic cell i is in the running and shutdown state at time t, respectively; Let i be the energy consumption power of electrolyzer i in time period t. Let be the hydrogen production efficiency of electrolyzer i during time period t.

[0083] Non-hydrogen production energy consumption can be calculated using the insulation energy consumption-time fitting function:

[0084]

[0085] in, The state of the hydrogen electrolyzer is a 0-1 variable. =0 and =1 indicates that electrolytic cell i is in the running and stopped state respectively during time period t. Let be the heat preservation energy consumption of electrolytic cell i during time period t.

[0086] From the above formulas for calculating hydrogen production energy consumption and non-hydrogen production energy consumption, it can be seen that when some electrolyzers produce hydrogen and others do not, the energy consumption calculation formula can be:

[0087]

[0088] In addition, the constraints on these multiple electrolyzers include not only the minimum and maximum safe power, but also the energy power required to power the hydrogen production system. Therefore, the limitations on the hydrogen production power of these electrolyzers also include:

[0089]

[0090] Among them, the This represents the minimum value among the minimum safe power of all electrolytic cells in the plurality of electrolytic cells. Characterized by the energy power that provides energy to the hydrogen production system.

[0091] Based on the above energy consumption calculation formula and the constraints of the multiple electrolytic cells, the objective function can be constructed as follows:

[0092]

[0093] By obtaining the minimum value of the above objective function, the specific hydrogen production power allocation data for allocating the remaining hydrogen production power to the target electrolyzer can be obtained.

[0094] In this way, by allocating the remaining hydrogen production power to the target electrolyzer according to the second preset power allocation method, it is beneficial to improve the hydrogen production efficiency of the target electrolyzer, save energy consumption, and improve energy utilization efficiency.

[0095] S105. Control the hydrogen production of the one or more target electrolyzers according to the hydrogen production power allocated to the one or more target electrolyzers.

[0096] In this step, the total hydrogen production power can be allocated to the target electrolyzer for hydrogen production based on the specific hydrogen production power allocation data obtained in steps S101 to S104 above.

[0097] By adopting the above technical solution, based on the total hydrogen production power and the minimum safe power of each of the multiple electrolyzers pre-set, one or more target electrolyzers are determined from the multiple electrolyzers; the total hydrogen production power is allocated to the one or more target electrolyzers according to a first preset power allocation method; and the remaining hydrogen production power is allocated to the one or more target electrolyzers according to a second preset power allocation method. In this way, by prioritizing the hydrogen production control method that meets the minimum safe power of the electrolyzer, the hydrogen production efficiency of the electrolyzer is improved, and by allocating the remaining hydrogen production power according to the power efficiency curve of the electrolyzer, the hydrogen production system can produce more hydrogen with the same energy consumption, thus improving energy utilization efficiency.
