[0053] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0056] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0057] The embodiment of the present application provides an energy router for a hybrid hydrogen production system, which may include multiple power generation interfaces, and different power generation interfaces are used to couple with different power generation units. Figure 1Taking the architecture shown in the figure as an example, the power generation unit is a new energy power generation unit, which includes a photovoltaic power generation unit, a wind power generation unit, a hydropower generation unit and a tidal power generation unit. In some schemes, a biomass power generation unit may also be included. Different power generation units may include one or more.

Accordingly, the energy router has a power generation interface coupled with the n power generation units. In actual application, the power generation interface can match the number and type of the actually connected power generation units.
[0058] The hybrid hydrogen production system includes n hydrogen production modules, of which 1-(m-1) are alkaline hydrogen production modules and mn are PEM hydrogen production modules. The energy router has corresponding 1 to (m-1) output ports connected to the alkaline hydrogen production modules, and mn output ports connected to the PEM hydrogen production modules.
[0059] It can be understood that in actual application, the number of power generation units and the number of hydrogen production modules may be the same or different.
[0060] As shown in the figure, the energy router is equipped with a power supply unit, and the power supply unit can adopt a low-power power supply unit. The low-power power supply can adopt battery energy storage, fuel cell power generation unit or other energy storage equipment, and is used as an emergency power supply for the energy router. Among them, the electric energy generated by the small-power power supply unit is used to meet the normal power supply and basic frequency of various auxiliary equipment when the new energy output is insufficient and the system is in standby state, so as to ensure that the hydrogen production system is in a hot standby state. Preferably, the small-power power supply unit adopts a fuel cell power generation unit, and the hydrogen produced by the alkaline hydrogen production module and the PEM hydrogen production module can be directly used to generate electricity. Alternatively, as shown in the connection method in the figure, the power supply unit itself is coupled and connected to each external power supply including the new energy power generation unit, and when the energy router is in working state, the power supply unit receives and stores the electric energy of the external power supply.
[0061] As shown in the figure, the power generation interface is used as the input port of the energy router. According to the type of the new energy power generation unit coupled to it, different converters are used to convert the connected electric energy. The converted electric energy is connected to the energy router. As shown in the figure, each converter is equipped with a local controller as a converter controller. The alkaline hydrogen production module and the PEM hydrogen production module are coupled and connected to the output port of the energy router as the output devices of the energy router. Each output port of the energy router is provided with a converter and a local controller matching the output device.
[0062] Furthermore, if Figure 1As shown, the central controller of the energy router is configured with an energy management module, a coordination control module, a communication module, a fault protection module, a hydrogen production status monitoring module and a load type active identification module. The energy management module is used to schedule the hydrogen production module and send scheduling instructions; the coordination control module formulates the real-time operation instructions of each hydrogen production module based on the scheduling instructions and controls the operation status of each hydrogen production module based on the real-time operation instructions; the communication module is used to realize the communication connection between the energy management module, the coordination control module, the hydrogen production status monitoring module, the fault protection module and the load active identification module, as well as the central controller and the power supply unit controller; the hydrogen production status monitoring module is used to monitor the hydrogen and oxygen content and auxiliary equipment status information in each hydrogen production module; the fault protection module is used to diagnose and clear the faults of each hydrogen production module and the redundant allocation between each hydrogen production module; the load active identification module detects the type of hydrogen production module by impedance method or equipment response rate, and determines the control logic and parameters associated with the type of hydrogen production module according to the type of hydrogen production module. When implemented specifically:
[0063] The energy management module is used to predict the power generation information of the new energy power generation unit and formulate the energy scheduling plan for each hydrogen production module of the hybrid hydrogen production system. The power generation information prediction of the new energy power generation unit includes the medium- and short-term prediction of the output power of the new energy power generation unit. The power generation information prediction of the new energy power generation unit is based on the medium- and short-term weather forecast, specifically including information such as temperature, light intensity, wind speed, water flow, etc., combined with a large amount of historical data, based on prediction algorithms such as regression algorithms, time series algorithms, neural network algorithms, etc., respectively, with minutes and hours as the time scale, predict the medium- and short-term output power of the new energy power generation unit, and provide data for the energy scheduling plan. Among them, the energy scheduling plan for each hydrogen production module of the hybrid hydrogen production system is based on the photovoltaic day-ahead predicted power value, and comprehensively considers the power characteristics and basic parameters of each hydrogen production module of the hybrid hydrogen production system, establishes the energy management model of each hydrogen production module of the hybrid hydrogen production system, and formulates the medium- and short-term output plan of the hybrid hydrogen production system based on the scheduling algorithm, respectively, with minutes and hours as the basic scheduling period, and the energy scheduling algorithm is not limited to model predictive control, hybrid integer programming, genetic algorithm, etc.
[0064] The coordination control module includes real-time control and power quality compensation. The real-time control includes system black start and real-time power distribution compensation; the power quality compensation includes ripple control, voltage deviation, voltage flicker, etc.
[0065] The communication module is divided into upper layer communication and lower layer communication. The upper layer communication is responsible for the precise issuance of scheduling, operation control, and protection instructions; the lower layer communication mainly realizes the transmission of equipment-level coordinated control and protection of hydrogen production.
[0066] The hydrogen production status monitoring module is mainly used to monitor the hydrogen and oxygen content, auxiliary equipment status and other information in the hydrogen production system, and upload it to the energy management and fault protection unit.
[0067] The fault protection module includes fault diagnosis, fault protection mode, and fault rapid removal. The fault diagnosis classifies and warns faults by considering information such as DC fault current and fault voltage; the fault protection mode selects the protection mode according to the system fault characteristics, without limiting the directional current method and the segmented protection method; the fault rapid removal uses the circuit breaker and the power electronic equipment to perform joint actions.
[0068] Based on the above functional modules, the central controller in the embodiment of the present application can formulate a medium- and short-term output plan for the hybrid hydrogen production system based on the dispatching control algorithm, according to the medium- and short-term power forecast data of wind and solar power, the operation and cache status and parameters of the alkaline hydrogen production module and the PME hydrogen production module, with minutes as the basic dispatching period. The plan is issued to real-time control. The real-time control distributes power to each device in real time based on the dispatching instructions issued, combined with the real-time data of the alkaline hydrogen production module and the PME hydrogen production module; the real-time control can also realize dynamic compensation of the operation of each device based on the system power quality detection, and real-time correction of the distributed power to ensure that the power quality meets the system requirements, such as bus voltage fluctuations not exceeding ±7%, harmonics not exceeding 3%, and short-term voltage drops not exceeding 0.625s.
[0069] Furthermore, the load type active identification module in the above scheme has the functions of active load identification and adaptive control. Before the load device is powered on, the type of hydrogen production equipment can be automatically detected by impedance method or device response rate, and the control mode and control parameters can be updated. Specifically, the type of hydrogen production module is detected in the following way:
[0070] Method 1: Connect a low-frequency signal to the energy router to detect the voltage and current information of the electrolyzer port of each hydrogen production module; determine the electrolyzer impedance value according to the port voltage and current information; determine the type of the hydrogen production module according to the electrolyzer impedance value.
[0071] Method 2: Connecting a current pulse signal to the energy router; obtaining a response slope of each of the hydrogen production modules when the current pulse signal is injected; and determining the type of the hydrogen production module based on a comparison result between the response slope and a preset standard response slope of each hydrogen production module.
[0072] In this solution, the hybrid hydrogen production interface may not limit the device type, and automatically detect the type of hydrogen production equipment through the impedance method or the device response rate, and update the control method and control parameters without defining each port.
[0073] In some other embodiments, a control method for an energy router of a hybrid hydrogen production system is provided, such as Figure 2 As shown, including:
[0074] S10: Monitor whether the external power supply of the hybrid hydrogen production system is disconnected.
[0075] S20: If the external power supply is disconnected, controlling the power supply unit to provide power and basic frequency to auxiliary equipment of the hybrid hydrogen production system.
[0076] In the scheme of this embodiment, when there is no power input to the hydrogen production system, the normal operation of the auxiliary equipment of the hydrogen production equipment is maintained, the hydrogen production time delay caused by the cold start of the hydrogen production system is avoided, the minimum operating requirements of the hybrid hydrogen production system are guaranteed, the frequent startup of the system is avoided, and the operating efficiency and service life of the hybrid hydrogen production system are improved.
[0077] Preferably, the above control method further includes:
[0078] S30: According to the operation objectives of the hybrid hydrogen production system, combined with the power generation prediction information of the new energy power generation, the energy consumption prediction information of the hybrid hydrogen production system, the hydrogen storage / cache prediction data of the hybrid hydrogen production system and the power consumption and power generation prediction data of the power supply unit, the system state of the hybrid hydrogen production system is determined; wherein, the system state of the hybrid hydrogen production system is determined based on a preset energy scheduling algorithm; the preset energy scheduling algorithm includes: model predictive control algorithm, hybrid integer programming algorithm and genetic algorithm.
[0079] S40: Determine the real-time operating status of each of the hydrogen production modules according to the system status of the hybrid hydrogen production system.
[0080] S50: Controlling the hydrogen production modules to operate in coordination according to the operating status.
[0081] When implementing it specifically, Figure 1 and Figure 3The energy management module establishes a system energy scheduling model based on the operation target of the hybrid hydrogen production system, combined with the prediction information of the power generation unit, the energy consumption prediction information of the hydrogen production system, the hydrogen storage / cache prediction data of the hydrogen production system, and the power consumption and power generation prediction data of the power supply unit. The output plan of each subunit of the hybrid hydrogen production system is formulated based on the energy scheduling algorithm, with minutes as the basic scheduling moment. The energy scheduling algorithm is not limited to model predictive control, hybrid integer programming, genetic algorithm, etc. The energy management module sends the output plan of each subunit of the hybrid hydrogen production system to the coordination control module. The coordination control module formulates real-time output instructions for each subunit of the hydrogen production based on the measured new energy power generation data, the hydrogen production demand data, the hydrogen storage / cache data of the hydrogen production system, and the operation data of the power supply unit, combined with the output plan of each subunit of the hydrogen production, and sends the output instruction to different converter controllers and power supply unit controllers to realize the coordinated operation of the hybrid hydrogen production system. The coordinated control has the ability to compensate for power quality, and dynamically generates the output command in combination with the real-time voltage fluctuation, harmonics and short-term voltage drop range of the terminal bus; the coordinated control module also has the ability to start in black. When the hybrid hydrogen production system operates in an isolated grid, it relies on its own new energy power generation unit and power supply unit to establish the system's basic frequency and voltage, and is not limited to voltage-frequency control and droop control.
[0082] Preferably, the above method further comprises:
[0083] S601: Connect a low-frequency signal to the energy router to detect the voltage and current information of the electrolyzer port of each hydrogen production module;
[0084] S602: Determine the impedance value of the electrolytic cell according to the port voltage and current information;

The type of hydrogen production equipment can be automatically detected through the impedance method or the device response rate, and the control mode and control parameters can be updated without defining each port.
[0091] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
