[0002] With the global energy structure transitioning towards renewable energy, wind power has become an important component of the power system. However, the inherent intermittency and volatility of wind energy lead to significant uncertainty in its power output. To achieve efficient energy integration, wind power-to-hydrogen technology has emerged and become a research hotspot. As the core equipment of a wind power-to-hydrogen system, the performance of the electrolyzer is highly dependent on the characteristics of the input electrical energy. Therefore, it is necessary to test and optimize the electrolysis process through simulation to improve the matching degree of system control strategies and operational efficiency.

[0003] Currently, the simulation and experimentation of wind power hydrogen production systems have obvious limitations: one approach relies on pure algorithm simulation, which is low in cost but has a large gap with the actual operating environment and lacks reliability; the other approach is to build a physical platform based on real wind turbines, converters and electrolyzers, which consumes a lot of resources, is extremely costly, and the test conditions are limited by natural wind speed, making it difficult to be flexible and controllable.

[0004] Furthermore, there is a lack of a wind power hydrogen production simulation system with multi-output and dynamic power distribution capabilities in the relevant technologies. Summary of the Invention

[0005] Therefore, it is necessary to provide a wind power hydrogen production simulation system and method that can dynamically allocate the output power of wind power hydrogen production simulation, addressing the aforementioned technical problems.

[0006] In a first aspect, this application provides a wind power hydrogen production simulation system, which includes: AC / DC converter module, the input terminal is used to connect to AC power; The DC / DC conversion module has its input end connected to the output end of the AC / DC conversion module, and its multiple output ends are used to connect to hydrogen electrolyzers with different power ratings. The controller, connected to the control terminal of the DC / DC conversion module, is used to acquire simulated wind power output parameters, select at least one hydrogen electrolyzer that matches the output power corresponding to the wind power output parameters, and adjust the power distribution of the DC / DC conversion module connected to the corresponding hydrogen electrolyzer.

[0007] In one embodiment, the DC / DC conversion module includes multiple DC / DC conversion modules; The input terminals of each DC / DC converter module are connected to the output terminals of the AC / DC converter module; The output terminals of each DC / DC conversion module are used to connect to hydrogen electrolyzers with different power ratings.

[0025] With the transformation of the global energy structure and the increasing emphasis on renewable energy, wind power, as a clean and sustainable energy source, is gradually becoming an important component of the power system. However, the intermittent and fluctuating nature of wind energy results in significant uncertainty in its power output. To achieve effective utilization of a high proportion of wind power, wind-to-hydrogen technology has been proposed and extensively studied.

[0026] In wind power-to-hydrogen systems, water electrolysis is the core component. The electrolyzer, as a key piece of equipment in this process, is significantly affected by parameters such as input power, voltage, and current. To improve the performance matching of the electrolyzer, optimize system control strategies, and assess overall efficiency, simulation and testing of the wind power-to-hydrogen system are typically required.

[0027] Currently, wind power hydrogen production technology is not mature. In most cases, the situation of wind power hydrogen production is inferred through algorithm simulation and simulation, but it is impossible to simulate the characteristics of wind power generation and conduct hydrogen production experiments in electrolyzers. This pure algorithm simulation has a large gap with the actual use environment and is not very reliable.

[0028] In some scenarios, data collection and control optimization are performed using actual wind power hydrogen production equipment. This method requires a great deal of resources, such as wind turbines, wind power converters, hydrogen production power supplies, and electrolyzers, making it extremely costly. Furthermore, the power generation is dependent on wind power and is uncontrollable.

[0029] Due to the difficulty in simulating the wind power hydrogen production environment, how to realistically simulate wind turbine power generation and verify hydrogen production is a major challenge before large-scale engineering implementation. This invention is a multi-output wind power hydrogen production simulation system used to simulate the output characteristics of wind farms and provide controllable power input to the electrolyzer. It is an indispensable tool in the system research, development, testing, and optimization process.

[0030] In addition, there is a lack of a wind power hydrogen production simulation system with multiple outputs and dynamic power distribution capabilities.

[0031] Based on the above reasons, this application provides a wind power hydrogen production simulation system and method, which can realize dynamic allocation and real-time adjustment of multiple power sources, enabling the wind power hydrogen production simulation system to have dynamic output power allocation capability.

[0032] In one exemplary embodiment, Figure 1 This is a schematic diagram of a wind power hydrogen production simulation system provided in an embodiment of this application, as shown below. Figure 1 As shown, the wind power hydrogen production simulation system 10 includes: an AC / DC conversion module 120, a DC / DC conversion module 130, and a controller 140, wherein: AC / DC conversion module 120, the input terminal is used to connect to AC power.

[0033] The AC / DC conversion module 120 can refer to an active rectifier or rectifier-filter circuit composed of fully controlled devices, which can be used to convert unstable AC power generated by an AC source into stable DC power, and can establish a DC bus to provide an energy source for subsequent DC / DC conversion.

[0034] The DC / DC conversion module 130 has its input terminal connected to the output terminal of the AC / DC conversion module 120. The multiple output terminals of the DC / DC conversion module 130 are used to connect to hydrogen electrolyzers 20 with different power ratings.

[0035] The DC / DC conversion module 130 can refer to an assembly containing multiple independent DC / DC conversion units. Each conversion unit has independent voltage, current and on / off control functions, which can be used to perform secondary conversion and distribution of the electrical energy of the DC bus to accurately adapt to the electrical parameter requirements of electrolytic cells with different rated power.

[0036] The controller 140 is connected to the control terminal of the DC / DC conversion module 130. It is used to acquire simulated wind power output parameters, select at least one hydrogen electrolyzer that matches the output power corresponding to the wind power output parameters, and adjust the power distribution of the DC / DC conversion module connected to the corresponding hydrogen electrolyzer.

[0037] The controller 140 can be a microprocessor unit (MCU) or digital signal processor (DSP) with a built-in power distribution algorithm. It can be used to collect system status parameters, store electrolytic cell power configuration information and generate PWM control signals to accurately manage the power flow direction and magnitude of each output channel.

[0038] For example, the input terminal of the AC / DC conversion module 120 can be connected to current or voltage; for instance, AC power can be connected from the power grid or from an AC generator, allowing simulated wind power AC power to be supplied to the AC / DC conversion module 120. The output terminal of the AC / DC conversion module 120 can be connected to the total input terminal of the DC / DC conversion module 130, supplying stable DC power to the DC / DC conversion module 130. Each independent output terminal of the DC / DC conversion module 130 can be connected to an electrolytic cell of a specific power. The controller 140 can perform AC / DC conversion by connecting to the AC / DC conversion module 120 and the DC / DC conversion module 130, realizing AC / DC power simulation conversion. It can also simulate the DC power output of the wind power hydrogen production simulation system by converting DC power. By monitoring the output power of each DC / DC conversion module 130 in real time and combining it with a preset power distribution algorithm, the controller can dynamically adjust the output voltage and current of each output terminal. It can select the matching hydrogen production electrolyzer according to the wind power output parameters and issue power distribution commands. For example, it can use PID control algorithm and state feedback mechanism to realize closed-loop correction to ensure that the power output of each channel is accurately matched with the requirements of the electrolyzer, thereby realizing a wind power hydrogen production simulation system with dynamic output power distribution capability.

[0039] Optionally, the communication bus of the controller 140 can be connected to the control interface of each DC / DC conversion module in the DC / DC conversion module 130, and its signal acquisition end can be connected to the sensors of each key node in the system.

[0040] Optionally, the AC / DC conversion module 120 may employ a three-phase full-bridge rectifier circuit to convert AC power to DC power. The DC / DC conversion module 130 may contain multiple Buck-Boost converters, each with a corresponding output terminal. The controller 140 may employ a digital signal processor (DSP) and communicate with the DC / DC conversion module 130 via a CAN bus.

[0041] In practical applications, the AC / DC conversion module 120 can be connected to AC power via the AC input interface to convert AC power into DC power. The input terminal of the DC / DC conversion module 130 is connected to the output terminal of the AC / DC conversion module 120, and can receive DC power. The controller 140 can be connected to the control terminal of the DC / DC conversion module 130 to achieve dynamic power allocation through the following steps: simulated wind power output parameters can be obtained through the communication interface, including real-time power, voltage fluctuation range and rate of change, etc. Based on a preset power matching algorithm (such as capacity priority matching or efficiency optimal matching), at least one target electrolyzer that matches the current wind power output parameters is selected from multiple hydrogen electrolyzers. A power allocation scheme can be generated according to the rated power of the target electrolyzer and the current operating conditions. The voltage and current of the output terminal of the DC / DC conversion module connected to the target electrolyzer can be adjusted through PWM control signals to ensure that the target electrolyzer is in a full-load operating state. At the same time, the matching degree between the output power and the electrolyzer's requirements can be monitored in real time through the status feedback channel. If the deviation exceeds the threshold, secondary adjustment can be triggered, thereby ensuring that the target electrolyzer is always in a full-load operating state.

[0042] In this embodiment, by setting up a DC / DC conversion module 130 with multiple independent output capabilities and coordinating it with a central controller 140, the parallel driving and precise power distribution of a single wind power simulation source to multiple electrolytic cells with different power is realized. This can greatly improve the testing efficiency and flexibility of the simulation device and overcome the limitation that traditional single-output simulation devices cannot meet the testing requirements of multiple electrolytic cells at the same time.

[0043] Furthermore, by adjusting the input power of each electrolyzer in real time, efficient operation of the electrolyzers can be maintained under different wind speed conditions, improving overall hydrogen production efficiency. Simultaneously, the dynamic power allocation mechanism reduces frequent start-ups and shutdowns of the electrolyzers due to power mismatch, thereby extending equipment lifespan. It also enables power priority control of multiple electrolyzers, maintaining partial hydrogen production capacity even under low wind speed conditions, thus improving wind power utilization and hydrogen production stability.

[0044] In one exemplary embodiment, Figure 2 A schematic diagram of a wind power hydrogen production simulation system with multiple DC / DC conversion modules is provided as an embodiment of this application, as shown below. Figure 2 As shown, it is possible to Figure 1 Based on this, the specific structure of the wind power hydrogen production simulation system 10 is further illustrated by example, wherein: DC / DC conversion module 130 includes multiple DC / DC conversion modules 131.

[0045] The input terminals of each DC / DC conversion module 131 are connected to the output terminals of the AC / DC conversion module 120.

[0046] The output terminals of each DC / DC conversion module 131 are used to connect to hydrogen electrolyzers 20 with different power ratings.

[0047] The controller 140 is connected to the control terminal of each DC / DC conversion module 131. The controller 140 is used to allocate and adjust the output power of each DC / DC conversion module 131 according to the output power corresponding to the wind power output parameters.

[0048] The DC / DC conversion module 131 can refer to a DC-DC converter circuit of type Buck, Boost, or Buck-Boost. Each module can be an independent power channel with independent hardware and software configurations, and can be customized according to the power level of the connected load.

[0049] For example, the unified DC bus voltage output by the AC / DC conversion module 120 can be connected in parallel to the input terminal of each DC / DC conversion module 131. Each DC / DC conversion module 131 can independently convert the bus voltage to the required output voltage and current values ​​by adjusting the duty cycle of its switching transistor, according to the rated voltage and current of its corresponding target electrolytic cell. The controller 140 can send commands to each DC / DC conversion module 131 through an independent communication link (such as a CAN bus or PWM signal) to set its target output power.

[0050] Specifically, when AC source 110 generates fluctuating AC power, AC / DC conversion module 120 can convert it into stable DC power and supply it to multiple parallel DC / DC conversion modules 131. Controller 140 can send a boost command to the corresponding DC / DC conversion module 131 based on a preset electrolytic cell power demand table. For example, if it detects that electrolytic cell #3 needs to be boosted to 80% of its rated power, the controller 140 can adjust the input voltage to match the electrolytic cell's output voltage through internal IGBT switching frequency adjustment. Power regulation between each DC / DC conversion module 131 can be independent; when an electrolytic cell stops, its corresponding DC / DC conversion module 131 can be completely shut down to avoid no-load losses. Thus, the independent control architecture allows for arbitrary proportional distribution of total power among different electrolytic cells; for example, the 20kW AC / DC output can be divided into 5kW, 8kW, and 7kW to supply the three electrolytic cells respectively.

[0051] In practical applications, flexible control of multiple power outputs can be achieved. Therefore, the output power of the corresponding DC / DC conversion module 131 can be adjusted according to the different power requirements of the hydrogen electrolyzers 20, improving the dynamic power allocation capability of the wind power hydrogen production simulation system 10, thereby enhancing the adaptability and flexibility of the system. Simultaneously, by setting up multiple DC / DC conversion modules 131, multiple hydrogen electrolyzers 20 with different power outputs can be powered simultaneously, improving the system's parallel processing capability and overall efficiency. Furthermore, the independent control of each DC / DC conversion module 131 by the controller 140 allows the system to more accurately match the power requirements of each hydrogen electrolyzer 20, thereby improving energy utilization efficiency.

[0052] In this embodiment, a distributed and modular DC / DC conversion architecture is adopted, which makes the system configuration more flexible and easier to expand and maintain. At the same time, the independent control of each power channel avoids mutual interference, realizes precise and independent power supply to each electrolytic cell, improves the dynamic power allocation capability, and meets the needs of complex test scenarios.

[0053] In one exemplary embodiment, Figure 3 This application provides a schematic diagram of the specific connection structure of a wind power hydrogen production simulation system 10; as shown in the embodiment of this application. Figure 3 As shown, it is possible to Figure 1 Based on this, the specific connections of the wind power hydrogen production simulation system 10 are further illustrated by example, wherein: The controller 140 is connected to the control terminal of the AC / DC conversion module 120.

[0054] The controller 140 is used to control the output power of the AC / DC conversion module 120 based on the wind power output parameters of the AC source 110, so that the output power of the AC / DC conversion module changes with time in accordance with the wind power output parameters.

[0055] Among them, wind power output parameters can refer to wind power output parameters determined by real-time voltage, current, frequency and power values, which can reflect the strength changes of simulated wind energy. For example, wind power output parameters can be the output parameters output by the wind turbine simulation module.

[0056] For example, the controller 140 can acquire the real-time output power corresponding to the wind power output parameters. Based on this power value, the controller 140 can dynamically adjust the DC bus voltage or total power output of the rectifier device in the AC / DC conversion module 120 by adjusting the control strategy (such as phase control or PWM modulation), so that the input energy at the front end and the total load energy allocated at the back end are kept in dynamic balance, thereby improving the energy utilization rate and operational stability of the entire system.

[0057] Specifically, the simulated wind power output parameters can be input or transmitted to the controller 140, which can convert the wind power output parameters into the target output power value of the AC / DC conversion module 120 according to a preset algorithm. The power semiconductor devices of the AC / DC conversion module 120 can adjust their conduction state according to the control signal to make the rectified DC power consistent with the power generation characteristics of the simulated wind turbine. For example, when the output power in the simulated wind power output parameters suddenly increases, the controller 140 can increase the DC voltage setting value of the AC / DC conversion module 120 to avoid triggering the protection mechanism due to the input power exceeding the capacity of the DC / DC conversion module 130. In this way, the output power of the AC / DC conversion module 120 can always match the dynamic characteristics of the wind power output parameters, providing an accurate simulated wind power output basis for the subsequent power allocation of the multi-channel hydrogen electrolyzer 20.

[0058] For example, when the wind power output parameters show an increase in wind speed, the controller 140 increases the output power of the AC / DC conversion module 120 accordingly; when the wind power output parameters show a decrease in wind speed, the controller 140 decreases the output power of the AC / DC conversion module 120 accordingly. Thus, the output power of the AC / DC conversion module 120 can be dynamically adjusted according to changes in wind power output.

[0059] In this embodiment, the output power of the AC / DC conversion module 120 is adjusted based on real-time wind power output parameters to ensure that the output power of the AC / DC conversion module 120 is consistent with the actual power generation of the wind turbine. This dynamic adjustment improves the simulation accuracy of the wind power hydrogen production simulation system 10, allowing the simulation device to more realistically reflect the operating status of the actual wind power hydrogen production system. Furthermore, by incorporating the front-end AC / DC conversion module 120 into a unified control loop, global coordination and optimization from wind energy simulation to DC power output are achieved. This provides a stable and reliable power input for subsequent DC / DC conversion and electrolysis hydrogen production processes, ensuring that the hydrogen production simulation device can operate efficiently and stably under different simulated wind conditions, thereby improving the realism and accuracy of the wind power hydrogen production simulation.

[0060] In one exemplary embodiment, Figure 4 This application provides a schematic diagram of the structure of a wind power hydrogen production simulation system with a wind turbine simulation module, as shown in the embodiments of this application. Figure 4 As shown, it is possible to Figure 1 Based on this, the structure of the wind power hydrogen production simulation system 10 will be further illustrated by example, wherein the wind power hydrogen production simulation system may further include: The wind turbine simulation module 150 is connected to the controller and is used to simulate and output the wind power output parameters.

[0061] The wind turbine simulation module 150 can refer to a programmable AC power supply device integrating a wind speed simulation algorithm. It may include a rectifier-inverter circuit, an energy storage unit, and a microprocessor. It can dynamically adjust the frequency, amplitude, and phase of the output AC power according to a preset wind speed curve to reproduce the wind power output characteristics of a real wind turbine under different wind conditions, providing power input that conforms to wind power fluctuations for the subsequent hydrogen electrolysis process. The wind turbine simulation module 150 can be integrated into the control system with the controller 140, or it can be a separate module from the controller 140; the specific implementation is not limited here.

[0062] For example, the wind turbine simulation module 150 can execute a wind speed-to-power conversion algorithm through its built-in microprocessor, receive externally input wind speed curve data or real-time wind speed commands, calculate the target output power of wind power by combining the wind turbine mathematical model (including tip speed ratio, power coefficient, and pitch angle adjustment characteristics), and dynamically adjust and correct the output wind power parameters, thereby accurately simulating wind power parameters under different wind speed conditions.

[0063] In this embodiment, the dynamic characteristic simulation of the wind turbine simulation module 150 enables the wind power hydrogen production simulation system to realistically reproduce the impact of the intermittency or fluctuation of wind energy on the real hydrogen production system, providing a reliable source of wind power input simulation for testing the response characteristics of the electrolyzer under different wind power conditions.

[0064] In one exemplary embodiment, such as Figure 4 As shown, the wind power hydrogen production simulation system also includes: AC power source 110, connected to the AC / DC conversion module, is used to provide input AC power.

[0065] Here, AC source 110 can refer to a system for AC input, such as an AC transmission network or an AC generator, to provide dynamic energy input for the wind power hydrogen production simulation system.

[0066] AC power source 110 can generate AC power.

[0067] For example, AC source 110 can provide AC power input to wind power hydrogen production simulation system 10 to provide power source for AC / DC conversion module 120. Controller 140 is used to control AC conversion, for example, by adjusting the PWM duty cycle of AC / DC conversion module to achieve stable AC to DC conversion, and also to control DC conversion distribution. Thus, a wind power hydrogen production simulation system with dynamic power simulation and multi-electrolyzer adaptation capabilities can be realized through AC source 110.

[0068] In one exemplary embodiment, such as Figure 3 As shown, controller 140 is connected to the output terminal of AC / DC conversion module 120; The controller 140 is used to control the output power of multiple output terminals of the DC / DC conversion module 130 based on the output power detected from the AC / DC conversion module 120.

[0069] The output on / off state can refer to the on and off state of the semiconductor switching devices (such as MOSFETs and IGBTs) in the output circuit of each DC / DC conversion module 131, so as to connect or disconnect the power supply to the corresponding electrolytic cell.

[0070] For example, the controller 140 can monitor the total DC power output by the AC / DC conversion module 120 in real time. Based on this total power and the preset power requirements of each electrolyzer, the controller 140 can execute a power allocation logic algorithm to calculate the specific DC / DC output channel that should be activated at the moment, and send an on or off command to the corresponding DC / DC conversion module 131. This ensures that the sum of the power required by all connected electrolyzers does not exceed the total power available in the current wind power simulation, thus achieving safe and reliable power management.

[0071] Specifically, the controller 140 continuously monitors the output power of the AC / DC conversion module 120 and performs matching calculations between the real-time power value and the rated power of each output terminal of the DC / DC conversion module 130. When the AC / DC output power changes, the controller 140 dynamically adjusts the conduction combination of the output terminals according to the current total power. For example, if the AC / DC output power drops from 800W to 600W, the controller 140 can shut down the original 800W output terminal and enable the two 300W output terminals to achieve power matching. This process ensures that the power distribution strictly corresponds to the actual AC / DC output through a real-time feedback mechanism, avoiding equipment damage caused by power mismatch, and improving the adaptability of simulated hydrogen production to wind power fluctuations.

[0072] For example, the controller 140 can control the on-time of the switching transistors of each DC / DC conversion module 131 in the DC / DC conversion module 130 through the PWM signal, thereby adjusting the output voltage and current of each output terminal and achieving precise control of the power of each output terminal.

[0073] In this embodiment, the power distribution of each output terminal of the DC / DC conversion module 130 can be flexibly adjusted according to the actual output power of the AC / DC conversion module 120, thereby improving the system's adaptability and flexibility. Furthermore, by controlling the on / off state of the output terminals of the DC / DC conversion module 130, hydrogen electrolyzers 20 with different power levels can be selectively started and stopped according to actual needs, ensuring that the hydrogen electrolyzers 20 operate at full load and avoiding energy waste caused by low-load operation, thus improving the energy utilization efficiency of the entire wind power hydrogen production system. Simultaneously, by dynamically managing the on / off state of the output channels based on the total available power, faults such as DC bus collapse and voltage drops caused by the total load demand exceeding the input supply can be effectively prevented, thereby enhancing robustness and safety.

[0074] In an exemplary embodiment, the total output power of at least two output terminals of the DC / DC conversion module used for outputting DC power is dynamically matched with the total rated power of the hydrogen electrolyzer. Specifically, the rated power parameters of each hydrogen electrolyzer can be collected in real time by the controller. Combined with the total input power of the DC / DC conversion module, the total power is allocated to each output terminal. The target power of each output terminal is calculated by a preset dynamic allocation algorithm (such as capacity ratio allocation or priority allocation), a PWM control signal is generated and sent to the corresponding DC / DC conversion module, and the duty cycle of the power device is adjusted to change the output voltage and current. At the same time, the actual power and current of each output terminal are monitored in real time by the status feedback unit, and closed-loop correction is performed by the PID adjustment algorithm to ensure that the power deviation of each output terminal is controlled within the preset deviation threshold. The current sharing control and data interaction between the modules are realized through the CAN bus so that each hydrogen electrolyzer can operate at full load under rated power.

[0075] In an exemplary embodiment, the total output power of at least two output terminals of the DC / DC conversion module used for outputting DC power is dynamically matched with the total rated power of the hydrogen electrolyzer. Specifically, the rated power parameters of each hydrogen electrolyzer can be collected in real time by the controller, and combined with the total input power of the DC / DC conversion module, the total power is distributed to each output terminal to ensure the output power of each output terminal, so that each hydrogen electrolyzer can operate at full load under rated power.

[0076] In an exemplary embodiment, the total output power of at least two output terminals of the DC / DC conversion module used for outputting DC power is dynamically matched with the total rated power of the hydrogen electrolyzer. The controller can collect the rated power parameters of each hydrogen electrolyzer in real time, and combine them with the total input power of the DC / DC conversion module. The total power is allocated to each output terminal through a dynamic allocation algorithm based on capacity priority. At the same time, the PWM duty cycle can be corrected through a PID adjustment algorithm to ensure that the deviation between the actual power of each output terminal and the rated power of the electrolyzer is controlled within a preset threshold, thereby enabling each hydrogen electrolyzer to operate stably at full load under rated power.

[0077] For example, if the DC / DC conversion module contains three independent modules with output capacities of 1MW, 2MW, and 3MW, respectively, and each module is connected to a hydrogen electrolyzer of the same power level; when the simulated wind power output is less than 3MW, the controller can start only the single electrolyzer matching the current power (such as 1MW or 2MW); when the simulated wind power output is 5MW, the controller can coordinate the start of a combined output of 2MW and 3MW electrolyzers. Compared to the scenario where a traditional single-output simulator needs to be matched with a 5MW electrolyzer, this solution can avoid efficiency losses caused by the electrolyzer being idle under low power conditions, thereby improving the resource utilization rate of the wind power hydrogen production simulation system.

[0078] For example, when wind conditions are favorable and the AC / DC module output power is high, the controller can control multiple DC / DC conversion modules to operate simultaneously, with each module driving one electrolyzer, and the sum of the output power of all modules equal to the output power of the AC / DC module. When wind conditions are poor and the AC / DC module output power is low, the controller can activate only one DC / DC conversion module to drive an electrolyzer with lower power requirements, and the output power of this module equals the output power of the AC / DC module. Through this dynamic matching, the controller ensures that electrical energy can be effectively utilized under any wind conditions, allowing the hydrogen production electrolyzer to operate at full capacity.

[0079] In one exemplary embodiment, Figure 5 This application provides a schematic flowchart of a wind power hydrogen production simulation method, applicable to the system described above. Figure 5 As shown, the method includes: S501. Obtain the simulated wind power output parameters and select at least one hydrogen electrolyzer that matches the output power corresponding to the wind power output parameters. S502. Adjust the power distribution of the DC / DC conversion module connected to the hydrogen electrolyzer.

[0080] Among them, wind power output parameters refer to electrical parameters reflecting wind energy characteristics output by the wind turbine simulation module. These parameters can include real-time power, voltage amplitude, frequency, power fluctuation range, and rate of change, and can be used to characterize the power output characteristics of the simulated wind farm under different wind speed conditions. For example, wind power output parameters can be wind power output curves.

[0081] A matched hydrogen electrolyzer refers to an electrolyzer whose rated power range is compatible with the real-time power output parameters of the current wind power generation and can adapt to the fluctuations in wind power. Adjusting power distribution refers to the DC / DC converter module, under the controller's command, adjusting the PWM duty cycle of each output power device to change the voltage and current values ​​of the corresponding output channels, thereby dynamically distributing the total input power among multiple hydrogen electrolyzers and ensuring that the deviation between the actual input power and the rated power of each electrolyzer does not exceed a preset threshold.

[0082] For example, the controller can acquire wind power parameters input by the user, including basic parameters such as wind speed curve, rated power, and cut-in / cut-out wind speed. Further, it can perform power conversion calculations using a wind turbine mathematical model (including aerodynamic model, transmission chain model, and generator model), and combine this with real-time meteorological correction coefficients to obtain wind power output parameters. Wind power output parameters can also be generated through a wind turbine simulation module. For instance, the wind turbine simulation module can generate a simulated wind power output signal containing voltage fluctuations, frequency deviations, and power ramp-up characteristics based on preset dynamic characteristic parameters such as turbulence intensity, wind speed fluctuation frequency, and gust coefficient.

[0083] Select a hydrogen electrolyzer whose output power matches the wind power output parameters, and adjust the power distribution of the DC / DC conversion module connected to the corresponding hydrogen electrolyzer.

[0084] For example, if the output power of a wind power source is 5kW, the controller can select a hydrogen electrolyzer with a rated power of 5kW and allocate 5kW of power to it through the corresponding output terminal of the DC / DC conversion module. Alternatively, it can select multiple hydrogen electrolyzers with a total rated power of 5kW and allocate power to each hydrogen electrolyzer through the corresponding output terminal of the DC / DC conversion module. For example, if two hydrogen electrolyzers with a rated power of 2.5kW are selected, the controller sends a power allocation command to the DC / DC conversion module to allocate the 2.5kW power to the two output terminals respectively. Each output terminal can control the output voltage and current by adjusting the PWM duty cycle, and the actual power of each electrolyzer can be monitored in real time through the status feedback unit.

[0085] For example, during regulation, the IGBT switching frequency of each DC / DC module can be automatically adjusted according to load changes to stabilize the output voltage within a set range. When the total input power is insufficient, low-priority output channels can be shut down according to a preset priority algorithm to ensure continuous power supply to high-priority electrolytic cells. This process can be achieved through multi-threaded control.

[0086] In this embodiment, by selecting the target hydrogen production electrolyzer that matches the output power of the wind power output parameters in S501, and by dynamically adjusting the power distribution of the DC / DC conversion module in S502, the output power of the wind power output parameters and the electrolyzer can be accurately matched. This enhances the dynamic power distribution capability of the wind power hydrogen production simulation system, thereby improving the dynamic simulation output capability of the wind power hydrogen production simulation system and increasing the flexibility of the output.

[0087] In an exemplary embodiment, when the controller is connected to the control terminal of the AC / DC conversion module, the method includes: Based on the wind power output parameters, the output power of the AC / DC conversion module is controlled so that the change in the output power of the AC / DC conversion module over time is consistent with the wind power output parameters.

[0088] The control of the output power of the AC / DC conversion module can refer to the strategy of adjusting its control signal so that the output DC bus voltage or total current changes with the wind power output.

[0089] For example, the controller can calculate the real-time active power by acquiring the wind power output parameters. The controller uses this power value as a feedforward signal to generate control commands for the AC / DC conversion module through a specific control algorithm (such as PID control), so that the DC power output can quickly track the changes in the simulated wind power, thereby reflecting the fluctuation of wind energy on the DC bus in real time.

[0090] Optionally, the controller can acquire wind power output parameters from the wind turbine simulation module. These parameters may include data such as wind speed, wind direction, and wind turbine rotational speed. Based on the acquired wind power output parameters, the controller calculates the corresponding wind turbine output power. The controller can also send control commands to the AC / DC conversion module to adjust its output voltage and current, ensuring that its output power matches the calculated wind turbine output power.

[0091] In this embodiment, the controller can dynamically adjust the output of the AC / DC conversion module based on real-time wind data, ensuring that the output characteristics of the simulation system are consistent with those of an actual wind turbine. This enables front-end management of wind energy fluctuations, allowing subsequent power allocation to be based on a realistic and dynamic energy supply, thereby improving the simulation accuracy of the wind power-to-hydrogen simulation system.

[0092] In one exemplary embodiment, when the controller is connected to the AC / DC conversion module, the method includes: Receive the output power from the output terminal of the AC / DC conversion module; Based on the output power of the AC / DC conversion module, adjust the output power of multiple output terminals of the DC / DC conversion module.

[0093] The received output power refers to the real-time power obtained by collecting the voltage and current values ​​on the DC bus through voltage and current sensors and performing calculations.

[0094] For example, the controller can periodically read the measurements from voltage and current sensors connected to the DC bus and calculate the total available power. The controller may internally store a load switching logic (e.g., based on electrolytic cell priority or a preset order) that compares the total available power with the power requirements of each electrolytic cell, determining which cells to connect and which to disconnect. It can also send on / off commands to the electronic switching devices in the DC / DC conversion module to adjust and distribute the output power across multiple output terminals.

[0095] Optionally, when the output of the AC / DC conversion module is connected to the controller, the DC bus voltage and output current values ​​can be collected in real time using voltage and current sensors, and the output power can be calculated. For example, if the output power of the AC / DC conversion module is detected to be 500kW, the controller can call the pre-stored rated power parameters of each output of the DC / DC conversion module, such as 200kW for the first output, 300kW for the second output, and 500kW for the third output. According to the preset power matching logic, the third output can be selected to conduct, outputting 500kW of power to the corresponding electrolytic cell. When the output power of the AC / DC conversion module is detected to drop to 450kW, the controller can shut down the third output while activating the first and second outputs, making the total output power equal to 450kW. The on / off state of the output can be controlled by solid-state relays.

[0096] In this embodiment, through precise power detection and multi-output control logic, it is ensured that electrolyzers of different power levels can obtain appropriate input power, thereby enabling the wind power hydrogen production simulation system to have dynamic power allocation capability, dynamically manage the load according to the real-time available energy, and prevent the risk of shutdown due to overload.

[0097] In one exemplary embodiment, obtaining simulated wind power output parameters includes: Obtain wind power data input by the user, and simulate and determine wind power output parameters based on the wind power data; And / or, receive wind power output parameters output by the wind turbine simulation module connected to the controller.

[0098] Among them, wind data can refer to a set of basic parameters used to characterize wind energy characteristics, including wind speed, wind direction, turbulence intensity, wind speed change rate and gust coefficient, etc., to reflect the wind energy input characteristics under different meteorological conditions and provide raw data support for simulating wind power output parameters.

[0099] For example, a user can input wind power data into the controller, which can then acquire the input wind power data and convert it into a corresponding electrical power signal using a wind turbine mathematical model. This allows the controller to simulate and generate wind power output parameters that include real-time power, voltage fluctuations, and frequency characteristics.

[0100] And / or, it can receive wind power output parameters output by the wind turbine simulation module connected to the controller. These parameters can be dynamically generated by the wind turbine simulation module based on a preset wind speed curve or real-time meteorological data, and include electrical quantities such as voltage amplitude, frequency, active power and reactive power. The controller can receive these parameters through the CAN bus or Ethernet interface and process them as the basis for power allocation.

[0101] In this embodiment, by combining user input with module output to obtain wind power output parameters, the flexibility and accuracy of wind energy characteristic simulation can be achieved. It can not only convert wind power data into electrical power signals that conform to the characteristics of actual wind farms, but also directly receive dynamic electrical parameters generated by the simulation module, providing a multi-dimensional simulation data foundation for subsequent power allocation. This can improve the adaptability of the wind power hydrogen production simulation system to different test scenarios and the power control accuracy.

[0102] In some exemplary embodiments, the wind power hydrogen production simulation system and method provided in this application are illustrated with reference to the structure and control of the aforementioned wind power hydrogen production simulation system. The following can be considered as specific implementations of this application, such as... Figure 6 As shown, Figure 6 This application provides a schematic diagram of the specific structure of a wind power hydrogen production simulation system, which includes the following modules: Wind turbine simulation module: Three-phase AC voltage input, providing input power for the entire system.

[0103] AC / DC conversion module: Converts the input three-phase AC voltage to DC voltage. All DC / DC conversion modules draw power from this DC voltage.

[0104] DC / DC conversion module: Includes multiple independent DC-DC conversion modules, each of which can independently adjust the output voltage and current to drive multiple electrolytic cells respectively.

[0105] The controller can dynamically adjust the output of each DC / DC conversion module according to the power requirements of the electrolyzer, so as to achieve reasonable power distribution; it can collect data such as voltage, current and power of each module in real time, support data analysis and storage, and facilitate subsequent research and optimization; and it can simulate the output fluctuation characteristics of the wind farm based on the input wind speed, wind direction and wind turbine parameters.

[0106] The wind power-to-hydrogen simulation system can be scheduled via a controller, providing multiple outputs and supporting simultaneous power supply and independent control of multiple electrolyzers to improve testing efficiency, reduce costs, and enhance system simulation capabilities. It also supports simulating the wind power output curve of wind turbines, dynamically adjusting the load of electrolyzers based on the curve, optimizing scheduling strategies, increasing the load duration, and, combined with specific wind speed probability distribution characteristics, conducting wind-hydrogen collaborative optimization design to effectively smooth wind power fluctuations and improve energy utilization efficiency. Specific implementation methods are as follows: Input the simulated wind power output curve (i.e., wind power processing parameters) into the controller: The wind power output curve can be a curve describing the power output characteristics of the wind turbine under different wind speed conditions. Wind speed is related to environmental factors, time, and other factors. Therefore, the final curve is a time versus power curve, used to simulate the fluctuation characteristics of the wind farm output.

[0107] The controller controls the output power of the AC / DC module according to the wind power output curve, so that the relationship between its output power and time is consistent with the curve.

[0108] The controller adjusts the output power of the DC / DC module based on the current power to keep the electrolytic cell it drives operating within the optimal efficiency range, avoiding inefficient operation or frequent start-stop.

[0109] The efficiency and output hydrogen volume of an electrolyzer are closely related to its input power. Electrolyzers can only operate efficiently after reaching a certain power level, typically exhibiting higher efficiency in the medium-to-high power range. However, electrolyzer power regulation response is slow, making frequent adjustments unsuitable. To increase the load duration of the electrolyzer and match the volatility of wind power, a multi-timescale adjustment strategy is adopted for power dispatching. The specific implementation is as follows: Short-term: When the short-term power fluctuates on an hourly basis, the wind power output fluctuates less. The controller adjusts the output power of each DC / DC in real time to match the wind power output.

[0110] Mid-term: During the mid-term, when power fluctuates daily, wind power output fluctuates significantly. Since the electrolyzer's power adjustment response is slow, frequent adjustments are not suitable. Therefore, at this stage, adjustments can be made based on the daily wind power output fluctuations, combined with wind speed forecasts and load demand, to formulate an operating plan and maximize the efficiency of hydrogen production from the electrolyzer.

[0111] For example, the DC / DC modules of this wind power hydrogen production simulation system have output capacities of 1MW, 2MW, and 3MW, respectively, which are connected to electrolyzers of corresponding power levels. If the simulated daily wind power output is less than 3MW, only the corresponding power electrolyzer can be started; if the simulated daily wind power output is 5MW, both the 2MW and 3MW electrolyzers can be started simultaneously. If the original single-output wind power hydrogen production simulation system is used, only the 5MW electrolyzer can be considered for startup, which would lead to low hydrogen production efficiency when the wind power output is low.

[0112] Long-term: When the time span is measured in years, the wind power output varies greatly between different times and seasons. This time, the capacity configuration of the electrolyzer can be optimized based on the annual wind speed distribution and grid demand, and the output characteristics of each DC / DC output module can be reasonably set.

[0113] Optionally, the wind power hydrogen production simulation system can simultaneously output multiple DC voltages to power multiple electrolyzers, with the voltage and current of each output independently adjustable and without interference. It can implement load matching and power distribution strategies for multiple outputs, supporting parallel, independent, or coordinated power supply to multiple electrolyzers. The control system can centrally control and coordinate multiple DC-DC modules to simulate the fluctuating characteristics of wind farm outputs and provide adjustable and independently controllable power inputs to multiple electrolyzers. Multi-timescale scheduling strategies can be employed to increase the load duration of the electrolyzers and match the volatility of wind power.

[0114] In practical applications, it breaks through the limitations of the traditional wind power hydrogen production simulation system with its single-channel output, significantly improving the simulator's practicality and testing capabilities.

[0115] In this embodiment, the wind power hydrogen production simulation system and method provided in this application can have multi-output capability: supporting simultaneous power supply to multiple electrolyzers, simulating the scenario of multiple loads operating in parallel in a real wind power hydrogen production system, improving the accuracy and comprehensiveness of the test. It achieves modular design: each DC-DC module can work independently or collaboratively, supporting flexible configuration and rapid expansion to meet the experimental needs of different scales and types. It achieves high-precision control: the main control system can precisely adjust the output of each DC-DC module, realizing independent control and load matching of each electrolyzer. It achieves good cost-effectiveness: compared with the traditional method requiring multiple independent devices, this invention greatly reduces the purchase and maintenance costs of testing equipment and improves resource utilization.
