[0002] The hydrogen production power supply is a core component of the hydrogen production system. Its main function is to provide stable, high-quality DC power to the electrolyzer. During hydrogen production, the power supply needs to meet the requirements of low voltage and high current output, and be able to adapt to the operating needs of the electrolyzer over a wide power range. Simultaneously, to ensure the efficient, safe, and stable operation of the hydrogen production system, extremely high requirements are placed on the power quality (such as current ripple and steady-state accuracy) and dynamic response speed of the power supply.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The hydrogen production power supply is a core component of the hydrogen production system. Its main function is to provide stable, high-quality DC power to the electrolyzer. During hydrogen production, the power supply needs to meet the requirements of low voltage and high current output, and be able to adapt to the operating needs of the electrolyzer over a wide power range. Simultaneously, to ensure the efficient, safe, and stable operation of the hydrogen production system, extremely high requirements are placed on the power quality (such as current ripple and steady-state accuracy) and dynamic response speed of the power supply.

[0032] Currently, hydrogen production power supplies generally employ the traditional current PI (proportional-integral) control method. This method involves real-time acquisition of the power supply output current, comparison with a set current value, generation of an error signal, and then calculation by the PI controller to generate drive pulses for adjusting the power supply switching devices.

[0033] However, PI controllers are single-loop feedback controllers, and their response speed is limited by the controller bandwidth. When faced with rapid power fluctuations or sudden load changes, the dynamic response of PI control lags and is prone to overshoot or oscillation. In other words, the control of hydrogen production power supply is prone to overshoot and oscillation, which cannot meet the requirements of hydrogen production system for rapid response.

[0034] To address the aforementioned technical problems, this application proposes a power control method. The following detailed description of the power control method is provided through various embodiments.

[0035] Reference Figure 1 , Figure 1 A flowchart of a power control method provided in this application embodiment Figure 1 .like Figure 1 As shown, the power control method provided in this embodiment includes: Step S101: Obtain the actual current value of the hydrogen production power supply at the current moment, and determine the expected current value of the hydrogen production power supply under the first-order inertial step response based on the actual current value.

[0036] In this embodiment, the executing entity is a power control device. For ease of description, the term "device" will be used to refer to the power control device below. The device can be the hydrogen production power source itself, or a device used to control the hydrogen production power source. During the process of the hydrogen production power source providing current to the electrolyzer for hydrogen production, the device will collect the current value of the hydrogen production power source to the electrolyzer in real time, and use the currently collected current value as the actual current value of the hydrogen production power source at the current moment.

[0037] After obtaining the actual current value, the desired current value of the hydrogen production power supply under the first-order inertial step response is determined based on the actual current value. For example, for the step response of the electrolyzer current, it is desired that the electrolyzer current exhibits a dynamic change process of a first-order inertial element with no overshoot, no oscillation, and small steady-state error. Therefore, a first-order filter element is used to generate the desired trajectory. The desired trajectory is an output current change curve composed of P discrete desired current values ​​w(k+1) at time K. The desired trajectory can be expressed as: ,in, The smoothness of the desired trajectory (range 0~1). The smaller the value, the faster the expected trajectory response; The current setting value for the hydrogen production power supply. This is the actual current value.

[0038] Step S102: Determine the predicted current value of the hydrogen production power source at the next moment based on the expected current value.

[0039] After obtaining the desired current value, the predicted current value of the hydrogen production power source at the next moment is determined based on the desired current value. For example, the predicted current value I(k+1) = × +（1- ）× ， in, The attenuation coefficient is the attenuation coefficient. , This represents the desired current value.

[0040] Step S103: Perform rolling optimization on the predicted current value to obtain the target current value, and determine the target current adjustment value based on the target current value.

[0041] After determining the predicted current value, the target current value can be obtained by performing rolling optimization on the predicted current value. For example, the previous current adjustment value of the hydrogen production power source can be obtained, and the predicted current value can be compensated based on the previous current adjustment value to obtain the target current value. For example, the sum of the predicted current value and the current predicted current can be used as the target current value.

[0042] Once the target current value is determined, the target current adjustment value can be determined. For example, the difference between the target current value and the actual current value at the current moment is used as the target current adjustment value.

[0043] Step S104: Adjust the current value currently output by the hydrogen production power supply according to the target current adjustment value.

[0044] After determining the target current adjustment value, the current value currently output by the hydrogen production power supply is adjusted based on the target current adjustment value; that is, the target current adjustment value is added to the current output current value of the hydrogen production power supply. In this embodiment, the hydrogen production power supply is controlled based on the desired current of the step response of first-order inertia, which has a certain robustness to changes in the hydrogen production system and can maintain good control performance of the hydrogen production power supply under different operating conditions.

[0045] In this embodiment, the actual current value of the hydrogen production power supply at the current moment is obtained, and the expected current value of the hydrogen production power supply under the first-order inertial step response is determined based on the actual current value. The predicted current value of the hydrogen production power supply at the next moment is then determined based on the expected current value. The predicted current value is then subjected to rolling optimization to obtain the target current value. Based on the target current value, a target current adjustment value is determined, and finally, the current output value of the hydrogen production power supply is adjusted using the target current adjustment value. In this embodiment, by using the expected current under the first-order inertial step response and performing rolling optimization on the predicted current, the current rise process can be accurately planned, effectively avoiding overshoot and oscillation phenomena common in PI control, and significantly improving the dynamic performance and stability of the hydrogen production system.

[0046] Reference Figure 2 , Figure 2 A flowchart of a power control method provided in this application embodiment Figure 2 ,based on Figure 1 In the embodiment shown, step S102 includes: Step S201: Predict the current value of the hydrogen production power source at the next moment based on the expected current value, use it as an intermediate current value, and determine the prediction current error.

[0047] In this embodiment, the predicted current value of the hydrogen production power source at the next moment is first determined by the expected current value, and this value is used as an intermediate current value.

[0048] For example, the intermediate current value I(k+1) = × +（1- ）× ， in, The attenuation coefficient is the attenuation coefficient. , This represents the desired current value.

[0049] After determining the intermediate current value, the predicted current error is then determined. In one example, the predicted current error is obtained by subtracting the actual current value from the intermediate current value.

[0050] In another example, a reference current value is determined based on the current current adjustment value of the hydrogen production power source and the smoothness of the expected current value. The predicted current error is then determined by the difference between the intermediate current value and the reference current value. For example, the predicted current error... ,in, = , For smoothness, This is the current current adjustment value. This is the intermediate current value.

[0051] Step S202: Based on the predicted current error, the intermediate current value is compensated to obtain the predicted current value of the hydrogen production power source at the next moment.

[0052] After obtaining the predicted current error, the intermediate current value is compensated for by the predicted current error to obtain the predicted current value. In one example, the predicted current error is superimposed on the intermediate current value to obtain the predicted current value. In another example, a compensation matrix is ​​obtained, and the intermediate current value is supplemented based on the product of the compensation matrix and the predicted current error to obtain the predicted current value. For example, the predicted current value is represented as: , To supplement the coefficients, which take values ​​between 0 and 1, the matrix representation is as follows: ,in, Both are P×1 matrices. To predict current error.

[0053] In this embodiment, accurate predicted current values ​​are obtained through error compensation and trajectory correction, thereby improving the stability accuracy of the hydrogen production power supply and reducing current ripple.

[0054] Figure 3 A flowchart of a power control method provided in this application embodiment Figure 3 ,based on Figure 1 or Figure 2 In the embodiment shown, step S103 includes: Step S301: Obtain the displacement matrix corresponding to the current rolling.

[0055] In this embodiment, the device obtains the displacement matrix S corresponding to the current rolling. Matrix S is a preset matrix. For example, the displacement matrix S is represented as: .

[0056] Step S302: Perform rolling optimization on the predicted current value based on the displacement matrix to obtain the target current value.

[0057] After obtaining the displacement matrix, the predicted current value is optimized using a rolling process based on the displacement matrix to obtain the target current value. In one example, the product of the predicted current value and the displacement matrix is ​​determined as the target current value, such as: ， Where S is the displacement matrix. For the target current value, To predict the current value.

[0058] In another example, the predicted current value is rolled over based on the displacement matrix to obtain the current value to be determined. Then, the dynamic matrix of the hydrogen production power source is determined. Based on the current value to be determined and the dynamic matrix, the target current value is determined. For example, the current value to be determined is: The dynamic matrix is ​​a preset matrix, therefore the target current value is: ,in, For the current dynamic matrix, The change in current that needs to be adjusted (this is an unknown parameter). The value of the current to be determined.

[0059] The current dynamic matrix A can be pre-stored based on actual measurements, and the device retrieves the current dynamic matrix from the storage area. When the electrolyzer powered by the hydrogen production power source is in steady-state operation, a step signal is applied to the current output by the hydrogen production power source to obtain the current values ​​of multiple electrolyzers. Based on the current values ​​of each electrolyzer, the current dynamic matrix of the hydrogen production power source is constructed.

[0060] For example, when the electrolyzer is operating in steady state, a step signal is applied to the current output by the hydrogen production power source to obtain the electrolyzer current step response curve, and the electrolyzer current values ​​a1, a2, a3, ..., a1 at P discrete sampling times are recorded. P Then, through the discrete values ​​of the step response a1, a2, a3, ..., a P Construct the eastward flow dynamic matrix A. The expression for matrix A is: Where P is the prediction step size and M is the control step size, M < P.

[0061] In this embodiment, the displacement matrix corresponding to the current rolling is obtained, and the predicted current value is rolled optimization based on the displacement matrix to accurately obtain the target current value.

[0062] Figure 4 A flowchart of a power control method provided in this application embodiment Figure 4 .based on Figures 1 to 3 In any of the embodiments shown, step S103 includes: Step S401: Obtain the steady-state constraints of the hydrogen production power source.

[0063] In this embodiment, the device obtains the steady-state constraints of the hydrogen production power source. The constraints include: the steady-state error value of the hydrogen production power source is less than a preset error value and / or the energy required by the hydrogen production power source in the steady-state state is less than a preset energy.

[0064] Step S402: Based on the constraints, construct the objective function relationship between the desired current value, the predicted current value, and the target current adjustment.

[0065] After obtaining the constraints, an objective function relationship is constructed between the desired current value, the predicted current value, and the target current adjustment value. For example, the objective function relationship is: Where q is the weighting factor for the system output tracking effect, and r is the weighting factor for the control quantity with the least energy. To predict the current value, The desired current value, This is the target current adjustment value.

[0066] Step S403: Determine the target current adjustment value based on the objective function relationship, the desired current value, and the predicted current value.

[0067] The target current adjustment value can be determined by using the objective function relationship, the desired current value, and the predicted current value. For example, under constraints, the objective function relationship is solved, that is, the constraint-satisfied value is obtained. As the target current adjustment value.

[0068] In this embodiment, the objective function relationship constructed based on constraints considers both output tracking accuracy and control energy, resulting in minimal current ripple and high steady-state accuracy in the hydrogen production system after reaching steady state, providing a high-quality and stable power supply for the electrolyzer. Furthermore, the objective function includes minimizing control energy waste (r*Δu²), meaning that the controller will minimize unnecessary control actions while ensuring performance, thereby reducing the control pressure on the hydrogen production power supply, lowering switching losses, and improving overall control efficiency.

[0069] Figure 5A flowchart of a power control method provided in this application embodiment Figure 5 .based on Figure 4 In the embodiment shown, step S403 includes: Step S501: Transform the objective function relationship into matrix form to obtain the intermediate function relationship.

[0070] In this embodiment, after determining the objective function relationship, the objective function relationship is transformed into matrix form. For example, the objective function relationship in matrix form is as follows: Where the Q matrix is ​​q×E p×p The R matrix is ​​r×E M×M E is the identity matrix. The objective function relation in matrix form is defined as the intermediate function relation.

[0071] Step S502: Based on the desired current value and the predicted current value, determine the optimal solution for the intermediate function relationship to obtain the target current adjustment value.

[0072] After obtaining the intermediate function relationship, the optimal solution of the intermediate function relationship is determined based on the expected current value and the predicted current value, and then the optimal solution is used as the target current value.

[0073] Furthermore, based on the desired and predicted current values, the optimal solution is obtained from the intermediate function relationship to arrive at the optimal output matrix. The first output element of the optimal output matrix is ​​then obtained, and the target current adjustment value is determined based on this output element and the current adjustment value of the hydrogen power supply at the previous moment. For example, the target current adjustment value is: Where ΔU(1,1) is the first output element of the optimal output matrix. It is the current adjustment value of the hydrogen production power source at the previous moment.

[0074] In this embodiment, the target current adjustment value is calculated more conveniently by performing a matrix transformation through the objective function relationship.
