[0025] Secondly, this application provides a method for simulating hydrogen production from wind power, applied to the aforementioned wind power hydrogen production simulation system, the method comprising:

[0026] The same wind power simulation parameters are issued to each wind power hydrogen production simulation device, and the working mode corresponding to at least one hydrogen production electrolyzer is determined.

[0027] According to the working mode of the hydrogen production electrolyzer, the output power of the wind power hydrogen production simulation device connected in groups at each output end is coordinated to test the working results of at least one hydrogen production electrolyzer under the input power corresponding to the wind power simulation parameters when it is in working mode.

Detailed Implementation

[0048] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0050] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.

[0051] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. Furthermore, in the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if there is transmission of electrical signals or data between the connected objects.

[0053] As the global energy structure transitions towards cleaner and lower-carbon energy, wind power, as an important form of renewable energy, continues to see its large-scale application expand. However, the inherent intermittency and volatility of wind energy lead to uncertainty in its output. To achieve efficient energy integration, wind power-to-hydrogen technology has become a key development direction. In this field, wind power-to-hydrogen simulators are used to simulate the power output of wind farms and the behavior of water electrolysis hydrogen production equipment to support the verification of system control strategies and performance evaluation.

[0054] Currently, these simulators are customized based on specific electrolyzer power levels, resulting in fixed power levels and insufficient scalability. They cannot adapt to different power testing scenarios or future system expansion needs, leading to high costs and long development cycles due to repetitive development. Furthermore, existing equipment struggles to achieve multi-machine parallel collaborative testing, limiting its verification capabilities for large-scale hydrogen production systems; and during low-power testing, it results in idle hardware resources, leading to low overall flexibility and resource utilization.

[0055] Therefore, wind power hydrogen production simulation systems suffer from at least the problems of fixed power levels and poor scalability.

[0056] For the reasons mentioned above, this application provides a wind power hydrogen production simulation system and method that can improve the scalability of wind power simulation.

[0057] 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: a wind power hydrogen production simulation device 120 and a central control device 130, wherein:

[0058] At least two wind power hydrogen production simulation devices 120 are set up in parallel.

[0059] The input terminals of each wind power hydrogen production simulation device 120 are used to connect to AC power, and the output terminals of each wind power hydrogen production simulation device 120 are connected in groups to each other. Each group connection is used to connect to the hydrogen production electrolyzer 20 corresponding to each group.

[0060] Optionally, the parallel-connected wind power hydrogen production simulation device 120 can refer to a group of power conversion units with the same topology. This parallel connection allows for the superposition of output capabilities, meeting the power supply requirements of high-power electrolyzers. The interconnected output terminals refer to dividing the output terminals of multiple wind power hydrogen production simulation devices into different groups according to a preset number or power level. Output terminals within the same group are electrically connected in parallel via a busbar, while different groups are independently connected to their corresponding hydrogen production electrolyzers. Specifically, the number of wind power hydrogen production simulation devices in each group can be flexibly configured according to the power requirements of the hydrogen production electrolyzer. Parallel connection in groups enables the superposition of output currents and power synthesis. Simultaneously, each group achieves differentiated power adjustment through independent control links to adapt to the simulated power supply requirements of different types or operating modes of hydrogen production electrolyzers.

[0061] The central control unit 130 is communicatively connected to each wind power hydrogen production simulation unit 120. The central control unit 130 is used to provide each wind power hydrogen production simulation unit with the same wind power simulation parameters and coordinate the output power of each wind power hydrogen production simulation unit 120 connected in groups according to the working mode of at least one hydrogen production electrolyzer 20, so as to test the working results of at least one hydrogen production electrolyzer 20 under the input power corresponding to the wind power simulation parameters when it is in the working mode.

[0062] The central control device 130 can refer to a computing device with centralized monitoring and coordination control functions, which can be used to uniformly issue power distribution commands and manage the coordinated operation of multiple parallel units.

[0063] Wind power simulation parameters refer to a set of key parameters used to characterize the output characteristics of wind turbine generators. Specifically, they may include simulated wind speed, voltage fluctuation range, frequency variation parameters, power ramp rate, and turbulence intensity. For example, wind power simulation parameters may be wind power simulation curves.

[0064] For example, the output bus of AC source 110 can be simultaneously connected to the input ports of each wind power hydrogen production simulator 120 through parallel branch lines, forming a distributed power distribution network to ensure that each device receives synchronous AC input. The DC output terminals of each wind power hydrogen production simulator 120 can be electrically connected in parallel through a busbar to jointly form the DC power supply system of hydrogen electrolyzer 20, realizing the superposition of output current and power synthesis. The central control device 130 can establish a bidirectional data interaction link with each wind power hydrogen production simulator 120 through a communication bus (such as CAN, 485 communication or Modbus), and can adopt a master-slave control architecture to realize command issuance and status feedback, ensuring the coordination and consistency of multiple devices during operation.

[0065] Optionally, in the wind power hydrogen production simulation system 10, each wind power hydrogen production simulation device 120 can be a module, which can operate independently or support the parallel operation of multiple modules, thereby realizing flexible configuration and expansion of output power; the power distribution and coordination control of the parallel wind power hydrogen production simulation devices 120 can be performed by the central control device 130 to ensure that the output power of each wind power hydrogen production simulation device 120 is matched and the current is balanced, avoiding circulating current and imbalance; the wind power hydrogen production simulation device 120 can be combined and configured for hydrogen production electrolyzers 20 of different power levels, adapting to a variety of application scenarios from small laboratory tests to large-scale engineering prototypes.

[0066] For example, wind power hydrogen production simulation devices can be modularly and freely combined according to testing needs, divided into several independent groups based on power level or electrolyzer type. Each group can be coordinated and controlled by a central control device 130, and can simultaneously drive different types of hydrogen production electrolyzers (such as PEM electrolyzers, alkaline electrolyzers, etc.) to achieve parallel testing in multiple scenarios. In specific applications, each group can be configured with 2-4 wind power hydrogen production simulation devices 120. Addressing the differentiated power requirements of 100kW-level PEM electrolyzers and 500kW-level alkaline electrolyzers, the output voltage and current of each group can be independently adjusted via a CAN bus. This supports simultaneous verification of the response characteristics of different electrolyzers to fluctuating wind power input in a laboratory environment, or comparison of hydrogen production efficiency and energy consumption indicators of different technical routes, thereby improving the flexibility and R&D efficiency of wind power hydrogen production testing.

[0067] In practical applications, by setting up groups in parallel, each group of independently connected hydrogen electrolyzers 20 can be tested independently to test the operating characteristics of the hydrogen electrolyzers 20 under different DC input power conditions at its rated power.

[0068] In this embodiment, a flexibly expandable power output system is constructed through a modular parallel design of multiple wind power hydrogen production simulation devices 120. The system capacity can be dynamically adjusted by adding or removing parallel devices according to the actual power requirements of the hydrogen electrolyzer 20, thus adapting to test scenarios for electrolyzers of different specifications. This not only enhances the system's adaptability to diverse application needs but also improves the utilization efficiency of equipment resources, providing a more flexible and practical simulation platform for the research and testing of wind power hydrogen production systems.

[0069] In one exemplary embodiment, Figure 2 This is an exemplary structural diagram of a wind power hydrogen production simulation device provided in 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 will be further illustrated by example, wherein the wind power hydrogen production simulation device 120 includes:

[0070] AC-DC conversion module 121, the input terminal of AC-DC conversion module 121 is connected to AC source 110, and is used to convert the AC power output by AC source 110 into DC power.

[0071] The control module 122 is communicatively connected to the central control device 130. It is used to receive wind power simulation parameters issued by the central control device and adjust the output power of the AC-DC conversion module 121 according to the power distribution command of the central control device 130, so as to realize the power expansion and distribution when multiple wind power hydrogen production simulation devices 120 are running in parallel.

[0072] The AC / DC conversion module 121 can be an AC / DC converter using full-bridge rectification or PWM rectification technology, which can be used to convert the unstable AC power output from AC source 110 into stable DC power. The control module 122 can be an embedded controller with a communication interface, which can be used to receive commands from the upper level and achieve precise control of the local power unit.

[0073] For example, the AC input terminal of the AC-DC conversion module 121 can be electrically connected to the AC source 110 through a circuit breaker with overload protection, and its DC output terminal can be connected to the DC bus system through a busbar to realize the collection and distribution of electrical energy. The control module 122 can establish a data interaction channel with the central control device 130 through an opto-isolated communication interface, and can also be connected to the power device drive circuit inside the AC-DC conversion module 121 through a PWM control signal to form a closed-loop control circuit.

[0074] Optionally, in the wind power hydrogen production simulation system 10, the upper layer can determine the output mode, output voltage, current, power, and other electrical characteristics through the central control device 130; the middle layer control can coordinate the current sharing and phase synchronization between the AC / DC conversion unit 121a and the DC / DC conversion units 121b between each module through master-slave control via the control modules 122 in each wind power hydrogen production simulation device 120. The lower layer control hardware can drive and execute PWM modulation and protection.

[0075] In this embodiment, by dividing the wind power hydrogen production simulation device 120 into a modular structure of AC / DC conversion module 121 and control module 122, a standardized design of the power conversion unit is achieved. This not only simplifies the expansion process of the system at different power levels but also facilitates the rapid replacement and maintenance of faulty units. Simultaneously, the distributed control architecture combining local control by control module 122 with global coordination by central control device 130 reduces communication delays and single-point-of-failure risks associated with centralized control, effectively improving the overall system's operational reliability and dynamic response speed.

[0076] In one exemplary embodiment, Figure 3 This application provides an exemplary structural diagram of an AC / DC conversion module, as shown in the embodiment of this application. Figure 3 As shown, it is possible to Figure 1 Based on this, the specific structure of the wind power hydrogen production simulation system 10 will be further illustrated by example, wherein the AC / DC conversion module 121 includes:

[0077] AC / DC conversion unit 121a has its input terminal connected to AC source 110 and is used to convert the AC power output from AC source 110 into DC power.

[0078] The input terminal of DC / DC conversion unit 121b is connected to the output terminal of AC / DC conversion unit 121a. The output terminal of DC / DC conversion unit 121b is used to connect to hydrogen electrolyzer 20 and to perform voltage conversion and power regulation of DC power according to the power distribution command of control module 122, so as to realize dynamic distribution of output power when multiple wind power hydrogen production simulation devices 120 are connected in parallel.

[0079] The AC / DC conversion unit 121a can be a power conversion device using uncontrolled rectification or PWM rectification technology, which can be used to convert AC input into pulsating DC power. The DC / DC conversion unit 121b can be a DC / DC converter with voltage regulation function, which can be used to realize DC voltage conversion and precise power control.

[0080] For example, the input terminal of AC / DC conversion unit 121a can be connected to AC source 110 through a filter, and the output terminal of AC / DC conversion unit 121a can be connected to the input terminal of DC / DC conversion unit 121b through an energy storage capacitor to form a two-stage power conversion link. The output terminal of DC / DC conversion unit 121b can be connected to DC bus through a current sharing resistor to achieve current balancing when multiple devices are connected in parallel.

[0081] In this embodiment, the AC / DC conversion architecture of AC / DC conversion unit 121a and DC / DC conversion unit 121b enables stable AC-to-DC conversion and precise power regulation, providing a standardized power conversion unit for the parallel operation of multiple wind power hydrogen production simulation devices 120, and improving the system's compatibility and expansion flexibility.

[0082] In one exemplary embodiment, the control module includes:

[0083] The communication unit is connected to the central control device and is used to receive power allocation commands sent by the central control device.

[0084] The power regulation unit, connected to the communication unit, is used to adjust the output voltage and current of the AC-DC conversion module according to the power distribution command;

[0085] The status feedback unit, connected to the power regulation unit, is used to feed back the real-time operating status information of the wind power hydrogen production simulator to the power regulation unit, so that the power regulation unit can balance the output current of the current wind power hydrogen production simulator and other wind power hydrogen production simulators.

[0086] The communication unit can refer to an interface module with data transmission and reception capabilities, used to establish a communication link between the control module and the central control device. The power regulation unit can refer to a controller employing a PID control algorithm, used to convert power allocation commands into specific voltage and current regulation parameters, enabling precise adjustment of output power. The status feedback unit can refer to a monitoring module integrating multiple sensors, such as voltage, current, and temperature sensors, used to collect the device's operating parameters.

[0087] For example, the communication unit can receive power distribution commands from the central control device via CAN bus, RS485 bus, Ethernet communication, etc., and transmit them to the power regulation unit. The power regulation unit can calculate the PWM duty cycle according to the commands and drive the AC-DC conversion module. The status feedback unit collects the output voltage and current data in real time and feeds them back to the power regulation unit to form a closed-loop control.

[0088] In this embodiment, a closed-loop control architecture of communication-regulation-feedback is used to achieve accurate reception and execution of power allocation commands, ensuring dynamic power balance when multiple devices are running in parallel, and improving the control accuracy and stability of the system.

[0089] In one exemplary embodiment, Figure 4 A schematic diagram of a wind power hydrogen production simulation system with data acquisition and monitoring functions is provided as an embodiment of this application. Figure 4 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 the wind power hydrogen production simulation system further includes:

[0090] The data acquisition module 140 is connected to the output end of each wind power hydrogen production simulation device to collect real-time operating parameters of the hydrogen production electrolyzer.

[0091] The power monitoring module 150 is connected to the central control device to monitor the output power of each wind power hydrogen production simulation device and send the monitoring results to the central control device to achieve dynamic power coordination.

[0092] The data acquisition module 140 can refer to a multi-channel data acquisition card or sensor group, which can be used to acquire operating parameters such as voltage, current, and temperature of the electrolytic cell. The power monitoring module 150 can refer to a power metering device based on a Hall sensor, used to monitor the output power of each device in real time.

[0093] For example, the data acquisition module 140 can be connected to the sensor interface of the electrolyzer via a shielded cable to acquire real-time operating parameters at a preset sampling rate. The power monitoring module 150 can acquire the output signals of each wind power hydrogen production simulator via current and voltage sensors, calculate the active power, and then send it to the central control device via a communication interface.

[0094] In this embodiment, the data acquisition module 140 and the power monitoring module 150 can provide the central control device with comprehensive system operation data, enabling dynamic power coordination to have an accurate data foundation, thereby improving the reliability of system control, and providing data support for fault diagnosis and performance optimization.

[0095] In one exemplary embodiment, the wind power hydrogen production simulation system described above further includes:

[0096] The fault protection module is connected in communication with the central control unit and is used to monitor the output parameters of the AC source;

[0097] The fault protection module is used to trigger overload protection or short circuit protection mechanisms when the output parameters are detected to exceed the preset safety threshold, and to send the fault status signal to the central control device so that the central control device can coordinate each wind power hydrogen production simulation device to reduce the output power or stop operation.

[0098] The fault protection module refers to a safety monitoring unit that integrates overvoltage, overcurrent, and overtemperature detection circuits. The preset safety thresholds can be determined based on system design parameters and electrolytic cell safety specifications.

[0099] For example, the sensor input terminal of the fault protection module can be connected to the output bus of an AC source to monitor voltage, current, and frequency parameters in real time. When a parameter is detected to exceed a threshold, the internally injected relay can actuate to cut off the main circuit and send a fault code to the central control device via protocols such as CAN bus, RS485 bus, or Ethernet.

[0100] In this embodiment, the fault protection module can effectively prevent damage to the system from abnormal operating conditions and improve the safety of equipment operation through real-time monitoring and rapid response mechanisms. At the same time, the linkage and coordination with the central control device ensures a stable system transition when a fault occurs, reducing the risk of fault escalation.

[0101] In some exemplary embodiments, such as Figure 3As shown, each wind power hydrogen production simulator may include a standard communication interface, an AC input interface, a control module, an AC / DC conversion unit, a DC / DC conversion unit, and a DC output interface. Each wind power hydrogen production simulator may have an independent control interface and can operate independently or in parallel with other modules.

[0102] Each wind power hydrogen production simulator can be connected via a standard electrical interface to achieve parallel power output. It can also be equipped with a standard communication interface to communicate with the central control unit. The control systems exchange data using a unified communication protocol (such as CAN, Ethernet, or RS485) to ensure the consistency of the parallel system operation.

[0103] The central control unit can coordinate the output power of each wind power hydrogen production simulation unit, dynamically allocate the operating power of each unit according to system testing requirements, and support multi-unit parallel control algorithms and current sharing algorithms to ensure power balance and system stability during parallel operation. A hierarchical control strategy can be adopted.

[0104] Upper-level control can determine the output mode, output voltage, current, power and other electrical characteristics through the central control device.

[0105] The mid-level control can coordinate the current sharing and phase synchronization between the AC / DC conversion unit and the DC / DC conversion unit between each device through master-slave control via the control modules in each wind power hydrogen production simulation device.

[0106] The underlying control hardware can drive and execute PWM modulation and protection.

[0107] Optionally, specific implementation methods may include:

[0108] The central control unit is the main controller, responsible for the coordination and management of the overall system, collecting data from various modules, and performing power distribution and coordinated control.

[0109] The control module in the wind power hydrogen production simulator is a slave controller, responsible for local power conversion, monitoring, and execution of instructions from the main controller.

[0110] Using protocols such as CAN bus, RS485, or Ethernet, real-time data transmission between the master controller and slave controllers is ensured, and a synchronization mechanism is used to ensure time synchronization of each module, avoiding timing issues.

[0111] The system monitors the output current of each module in real time, adjusts the output parameters of each module to balance the current, and uses a feedback mechanism to dynamically adjust the output of each module to ensure current balance and phase synchronization, thereby reducing circulating current.

[0112] After the control signal from the controller is transmitted to the underlying layer, the underlying driver adjusts the duty cycle of the PWM waveform signal and uses PID closed-loop to regulate the output voltage and current of the DC / DC conversion unit. At the same time, the underlying driver also has a protection mechanism that supports hardware protection such as overcurrent, overvoltage, and short circuit.

[0113] In this embodiment, modular design and standardized interfaces enable flexible expansion and independent operation of the wind power hydrogen production simulation device, meeting the testing requirements of different power levels. The hierarchical control strategy combined with a unified communication protocol ensures coordination and data consistency when multiple devices are running in parallel. The application of master-slave control architecture and current sharing algorithm effectively improves the system's power allocation accuracy and operational stability. The closed-loop regulation and hardware protection mechanism of the underlying driver further enhance the system's reliability and anti-interference capabilities, providing an efficient, safe, and scalable simulation platform for the testing and verification of wind power hydrogen production systems.

Figures 1 to 4 The wind power hydrogen production simulation system 10 shown is as follows: Figure 5 As shown, the method includes:

[0116] The determination of the working mode of the hydrogen electrolyzer 20 can be achieved by obtaining the core technical parameters and operating requirements of the hydrogen electrolyzer 20 through automatic system identification or manual configuration. Specifically, this includes the rated operating voltage range, rated operating current range, and preset operating control modes (such as constant voltage mode, constant current mode, or maximum power point tracking mode). This can provide a basic configuration basis for subsequent power coordination.

[0117] For example, the central control device 130 determines the working mode in the following ways: by reading the factory nameplate parameter information (such as rated voltage, rated current, electrolyzer type identification, etc.) of the hydrogen electrolyzer 20 through the data acquisition module, or by automatically identifying and matching by detecting the initial electrical characteristics of the electrolyzer (such as no-load voltage, internal resistance characteristics, etc.); at the same time, the system supports operators to manually select the preset working mode parameter set through the human-machine interface (such as touch screen, physical buttons or remote control terminal) to meet the needs of special test scenarios or manual debugging.

[0118] S502. According to the working mode of the hydrogen production electrolyzer, coordinate the output power of each wind power hydrogen production simulation device to test the working results of at least one hydrogen production electrolyzer under the input power corresponding to the wind power simulation parameters when it is in working mode.

[0119] The coordination of the output power of each wind power hydrogen production simulation device 120 can refer to the process by which the central control device 130 dynamically adjusts the output power ratio of each wind power hydrogen production simulation device 120 according to the working mode requirements of the hydrogen electrolyzer 20 through power allocation commands, thereby achieving a match between the total output power and the working mode. The working power corresponding to the working mode can refer to the real-time power value required by the hydrogen electrolyzer 20 under a specific operating mode (such as constant pressure or constant current).

[0120] For example, the central control device 130 can calculate the total power demand according to the working mode determined in S401, and generate a power distribution command by combining the real-time operating status of each wind power hydrogen production simulation device 120 (such as current output power and load capacity) through a preset current sharing algorithm. The power distribution command can be sent to the control module 122 of each wind power hydrogen production simulation device 120 via the communication bus. The control module 122 can adjust the output voltage and current of the AC-DC conversion module 121, and at the same time, it can monitor the output power in real time through the status feedback unit and feed it back to the central control device 130 to form a closed-loop regulation.

[0121] It should be understood that the wind power hydrogen production simulation method provided in this embodiment has a clear technical correspondence with the above-described wind power hydrogen production simulation system embodiment. The steps S501-S502 can be realized through communication interaction between the central control device 130 and the wind power hydrogen production simulation device 120, specifically relying on the hardware support of the communication unit, power adjustment unit, and status feedback unit in the control module 122. The dynamic power allocation logic in the method can correspond to the current sharing algorithm and hierarchical control architecture in the wind power hydrogen production simulation system. The command issuance and status feedback are realized through communication protocols such as CAN bus or Ethernet, forming a closed-loop control link to ensure the functional matching and technical logic consistency between the method steps and the system hardware components.

[0122] In this embodiment, through the coordinated control of working mode recognition and dynamic power coordination, precise control of the 20 operating points of the hydrogen electrolyzer is achieved, ensuring the power distribution balance when multiple devices are running in parallel. The introduction of the closed-loop feedback mechanism improves the system's response speed to load fluctuations, while the hierarchical control architecture enhances the flexibility and reliability of power regulation, providing a high-precision simulation environment for dynamic characteristic testing of wind power hydrogen production systems.

[0123] In one exemplary embodiment, the method further includes:

[0124] Collect real-time operating parameters of the hydrogen electrolyzer;

[0125] Monitor the output power of each wind power hydrogen production simulator; adjust the power distribution command of each wind power hydrogen production simulator according to the real-time operating parameters and the output power of each simulator.

[0126] Among these, real-time operating parameters refer to status parameters such as voltage, current, and temperature of the hydrogen electrolyzer during operation. Power coordination commands refer to control commands generated by the central control unit based on monitoring data, used to adjust the output power of each wind power hydrogen production simulator.

[0127] For example, the data acquisition module can collect electrolyzer parameters at a preset sampling frequency, the power monitoring module can simultaneously acquire the output power of each wind power hydrogen production simulation device, and the central control device can compare the real-time data with the rated parameters and adjust the power distribution command through the PID algorithm to stabilize the system output at the target value.

[0128] In this embodiment, the system's response speed to changes in operating conditions can be improved by combining real-time data acquisition with dynamic adjustment, thereby ensuring that the hydrogen electrolyzer operates at the optimal operating point. At the same time, it provides data support for fault diagnosis and enhances the reliability of the system.

[0129] In an exemplary embodiment, when the wind power hydrogen production simulation device includes a control module and an AC / DC conversion module, coordinating the output power of each wind power hydrogen production simulation device includes:

[0130] According to the working mode of the hydrogen electrolyzer, a power distribution command is sent to the control module.

[0131] The control module is used to adjust the output power of the AC / DC conversion module according to the power distribution command, so as to realize the power expansion and distribution when multiple wind power hydrogen production simulation devices are running in parallel.

[0132] Sending power allocation commands to the control module can refer to the process by which the central control unit issues specific power values ​​to the control modules of each wind power hydrogen production simulation unit based on the total power demand. Adjusting the AC / DC conversion module by the control module can refer to the control module changing the output power of the AC / DC conversion module by adjusting the PWM duty cycle, etc.

[0133] For example, the central control device can calculate the target power of each wind power hydrogen production simulation device according to the working mode of the hydrogen electrolyzer, package the power allocation command and send it through the communication bus, the control module parses the command and drives the AC-DC conversion module to execute it, and transmits the execution result back in real time through the status feedback unit.

[0134] In this embodiment, the burden on the central control device can be reduced by localizing the control module, thereby improving the system's response speed. At the same time, the standardized command interface facilitates system expansion and reduces the complexity of multi-device collaborative control.

[0135] In an exemplary embodiment, when the control module includes a communication unit, a power regulation unit, and a status feedback unit, the method further includes:

[0136] The power allocation command is sent to the communication unit of the control module, and the communication unit is used to transmit the power allocation command to the power regulation unit.

[0137] The power regulation unit is used to adjust the output voltage and current of the AC-DC conversion module according to the power distribution command. It is also used to balance the output current of the current wind power hydrogen production simulator with other wind power hydrogen production simulators based on the real-time operating status information of the wind power hydrogen production simulator fed back by the status feedback unit.

[0138] The process of the communication unit transmitting power distribution commands can refer to the accurate transmission of commands from the central control device to the power regulation unit through a reliable communication protocol. The process of the power regulation unit adjusting voltage and current can refer to the precise control of the AC / DC conversion module output based on the power distribution command parameters and a control algorithm.

[0139] For example, the communication unit may use CRC check to ensure instruction integrity, the power regulation unit may combine with, for example, a PI algorithm to adjust the output in real time, and the status feedback unit may provide feedback data with high-frequency sampling to form a fast closed-loop control.

[0140] In this embodiment, a modular control architecture is used to achieve efficient coordination of command transmission, power regulation and status monitoring, improve power control accuracy and system anti-interference capability, and provide a guarantee for current sharing control of multiple devices operating in parallel.

[0141] In an exemplary embodiment, when the system further includes a fault protection module, the method further includes:

[0142] The fault protection module monitors the output parameters of the AC source; if the output parameters exceed the preset safety threshold, the fault protection module will trigger overload protection or short circuit protection mechanisms.

[0143] Receive fault status signals sent by the fault protection module.

[0144] Based on the fault status signal, coordinate each wind power hydrogen production simulation unit to reduce its output power or stop operating.

[0145] Among these, the fault status signal refers to a signal generated by the fault protection module when it detects an anomaly, containing information such as the fault type and the time of occurrence. Coordinated reduction of output power or shutdown refers to protective measures taken by the central control unit based on the fault level.

[0146] For example, when the fault protection module detects overvoltage, it immediately cuts off the output and sends a fault signal. After receiving the signal, the central control device can quickly issue a power reduction command to each wind power hydrogen production simulation device and record the fault information at the same time.

[0147] In this embodiment, the linkage mechanism between the fault protection module and the central control device enables rapid fault detection and response, avoids damage to the system caused by the expansion of the fault, improves the safety of equipment operation, and provides a clear fault location basis for system maintenance.

[0148] In one exemplary embodiment, Figure 6 A schematic diagram of the specific structure of a wind power hydrogen production simulation system provided in this application embodiment is shown below. Figure 6 As shown, it is possible to Figure 1 Based on this, a detailed structural description of the wind power hydrogen production simulation device 120 is provided, including the wind power hydrogen production simulation system 10 and the method. Specifically, the wind power hydrogen production simulation system 10 may include an AC power source 110, the wind power hydrogen production simulation device 120, and a central control device 130; wherein:

[0149] AC power source 110 is connected to wind power hydrogen production simulation device 120 to provide input AC power.

[0150] 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.

[0151] For example, AC source 110 can provide AC power input to wind power hydrogen production simulation system 10, and can be used to provide power source for power conversion of AC / DC conversion unit 121a of wind power hydrogen production simulation device 120. Control module 122 of wind power hydrogen production simulation device 120 can be used to control AC conversion, for example, to achieve stable AC to DC conversion by adjusting the PWM duty cycle of AC / DC conversion unit 121a, and also to control DC conversion distribution, thereby realizing a wind power hydrogen production simulation system with multiple power parallel expansion.

[0152] In the wind power hydrogen production simulation system 10, each wind power hydrogen production simulation device 120 can be a module, which can operate independently or support the parallel operation of multiple modules, thereby realizing flexible configuration and expansion of output power. The power distribution and coordination control of the parallel wind power hydrogen production simulation devices 120 can be performed through the central control device 130 to ensure that the output power of each wind power hydrogen production simulation device 120 is matched and the current is balanced, avoiding circulating current and imbalance. The wind power hydrogen production simulation device 120 can be combined and configured for hydrogen production electrolyzers 20 with different power levels, adapting to a variety of application scenarios from small laboratory tests to large-scale engineering prototypes.

[0153] Standardized interface design: The modules use universal and standardized electrical and control interfaces to facilitate quick connection, disassembly and maintenance of the modules;

[0154] Unified Communication and Status Monitoring: Through a unified communication protocol and status monitoring system, information exchange and status synchronization between parallel modules are achieved, thereby improving the reliability and stability of the system.

[0155] Each wind power hydrogen production simulator 120 may include a standard communication interface, an AC input interface, a control module 122, an AC / DC conversion unit 121a, a DC / DC conversion unit 121b, and a DC output interface. Each wind power hydrogen production simulator 120 may have an independent control interface and can operate independently or in parallel with other modules.

[0156] Each wind power hydrogen production simulator 120 can be connected via a standard electrical interface to achieve parallel power output. It can also be equipped with a standard communication interface to communicate with the central control unit 130. The control systems exchange data using a unified communication protocol (such as CAN, Ethernet, or RS485) to ensure the consistency of the parallel system operation.

[0157] The central control unit 130 can coordinate the output power of each wind power hydrogen production simulation unit 120, dynamically allocate the operating power of each unit according to system testing requirements, and support multi-unit parallel control algorithms and current sharing algorithms to ensure power balance and system stability during parallel operation. A hierarchical control strategy can be adopted in the control strategy.

[0158] The upper-level control can make decisions on the output mode, output voltage, current, power and other electrical characteristics through the central control device 130.

[0159] The mid-level control can coordinate the current sharing and phase synchronization between the AC / DC conversion unit 121a and the DC / DC conversion unit 121b between each device through the master-slave control of the control module 122 in each wind power hydrogen production simulation device 120.

[0160] The underlying control hardware can drive and execute PWM modulation and protection.

[0161] Optionally, specific implementation methods may include:

[0162] The central control unit 130 is the main controller, responsible for the overall system coordination and management, collecting data from various modules, and performing power distribution and coordinated control.

[0163] The control module 122 in the wind power hydrogen production simulator 120 is a slave controller, responsible for local power conversion, monitoring and execution of the master controller's instructions.

[0164] Using protocols such as CAN bus, RS485, or Ethernet, real-time data transmission between the master controller and slave controllers is ensured, and a synchronization mechanism is used to ensure time synchronization of each module, avoiding timing issues.

[0165] The system monitors the output current of each module in real time, adjusts the output parameters of each module to balance the current, and uses a feedback mechanism to dynamically adjust the output of each module to ensure current balance and phase synchronization, thereby reducing circulating current.

[0166] After the control signal from the controller is transmitted to the underlying layer, the underlying driver adjusts the duty cycle of the PWM wave signal and uses PID closed-loop to regulate the output voltage and current of the DC / DC conversion unit 121b. At the same time, the underlying driver also has a protection mechanism that supports hardware protection such as overcurrent, overvoltage, and short circuit.
