Description

Technical Field

[0001] This application relates to the field of new energy control technology, specifically to a load regulation method, device, electronic equipment, and medium for an electro-hydrogen coupling system. Background Technology

[0002] With the continuous growth of installed capacity of renewable energy sources such as wind power and photovoltaics, hydrogen energy is playing an increasingly crucial role in energy systems due to its energy storage and cross-medium coupling characteristics. Electric-hydrogen coupling systems achieve spatiotemporal energy transfer and balance through water electrolysis and fuel cell power generation technologies. In electric-hydrogen control systems, load regulation is a key element in ensuring system power balance, operational stability, and energy utilization efficiency.

[0003] In current technologies for load regulation of electro-hydrogen coupling systems, a specific load value is used as a fixed setpoint, and this fixed setpoint is used as the regulation target. However, since the actual load of the system fluctuates, this rigid setting forces the system to frequently make large-scale adjustments to track a single fixed value. This not only exacerbates the wear and energy consumption of core equipment such as electrolyzers and compressors, but may also cause system instability due to drastic load regulation. Summary of the Invention

[0004] This application provides a load regulation method, apparatus, electronic device, and medium for an electro-hydrogen coupling system to solve the problem in related technologies where using a fixed setpoint as the load regulation target leads to frequent and large-scale adjustments by the system in order to track a single fixed value, which aggravates equipment wear and energy consumption, and may even cause system instability.

[0005] In a first aspect, embodiments of this application provide a load regulation method for an electro-hydrogen coupling system. The method includes: when the electro-hydrogen coupling system is determined to be in a target regulation mode, acquiring the real-time load value of the electro-hydrogen coupling system; performing a reset analysis on the load regulation range of the electro-hydrogen coupling system based on the interval position of the real-time load value relative to the load regulation range of the electro-hydrogen coupling system and the load operation status of the electro-hydrogen coupling system within a preset time window, to obtain analysis results; when the analysis results indicate that the load regulation range meets the reset conditions, resetting the load regulation range based on the target load value of the electro-hydrogen coupling system to obtain a target load regulation range adapted to the electro-hydrogen coupling system; and controlling the target device in the electro-hydrogen coupling system to regulate the load of the electro-hydrogen coupling system according to the target load regulation range.

[0006] In some embodiments of this application, the load adjustment range of the electro-hydrogen coupling system is reset and analyzed based on the interval position of the real-time load value relative to the load adjustment range of the electro-hydrogen coupling system and the duration of the real-time load value being in the interval position, so as to obtain the analysis results. Previously, the method included: when it was determined that the electro-hydrogen coupling system was in the target adjustment mode, obtaining the switching load value when the electro-hydrogen coupling system switched to the target adjustment mode, and determining the switching load value as the initial reference value; and constructing the load adjustment range of the electro-hydrogen coupling system based on the initial reference value.

[0007] In some embodiments of this application, constructing the load adjustment range of the electro-hydrogen coupling system based on an initial reference value includes: determining the upper limit and lower limit of the range based on the initial reference value and a preset adjustment ratio coefficient; and constructing the load adjustment range based on the upper limit and lower limit of the range.

[0008] In some embodiments of this application, based on the position of the real-time load value relative to the load adjustment range of the electro-hydrogen coupling system and the load operation status of the electro-hydrogen coupling system within a preset time window, a reset analysis of the load adjustment range of the electro-hydrogen coupling system is performed to obtain the analysis results. This includes: analyzing the position of the real-time load value relative to the load adjustment range of the electro-hydrogen coupling system to determine whether the real-time load value is in the boundary region of the load adjustment range; if it is determined that the real-time load value is in the boundary region, analyzing the load operation status of the electro-hydrogen coupling system within the preset time window, and resetting the load adjustment range of the electro-hydrogen coupling system according to the load operation status to obtain the analysis results.

[0009] In some embodiments of this application, the method analyzes the position of the real-time load value relative to the load adjustment range of the electro-hydrogen coupling system to determine whether the real-time load value is in the boundary region of the load adjustment range. Previously, the method included: determining the boundary region of the load adjustment range based on the load adjustment range and the boundary triggering coefficient.

[0011] In some embodiments of this application, the preset time window includes a first preset time window and a second preset time window. When the real-time load value is determined to be in a boundary region, the load operation status of the electro-hydrogen coupling system within the preset time window is analyzed. Based on the load operation status, the load adjustment range of the electro-hydrogen coupling system is reset and analyzed. The analysis results include: when the real-time load value is determined to be in a boundary region, taking the time of the real-time load value as the start point of the first preset time window, obtaining the first load value of the electro-hydrogen coupling system corresponding to the end time of the first preset time window; determining whether the first load value is in the boundary region of the load adjustment range based on the load adjustment range; and when the first load value is determined to be in the boundary region of the load adjustment range, analyzing whether the load adjustment range of the electro-hydrogen coupling system meets the reset conditions based on the load operation status of the electro-hydrogen coupling system within the second preset time window, thus obtaining the analysis results.

[0012] In some embodiments of this application, based on the load adjustment range, it is determined whether a first load value is within the boundary region of the load adjustment range. Then, the method includes: if the first load value is not within the boundary region of the load adjustment range, determining that the load adjustment range of the electro-hydrogen coupling system does not meet the reset condition, so as to maintain the load adjustment range unchanged.

[0013] In some embodiments of this application, when it is determined that the first load value is in the boundary region of the load adjustment range, based on the load operation status of the electro-hydrogen coupling system within a second preset time window, the analysis results are obtained by determining whether the load adjustment range of the electro-hydrogen coupling system meets the reset condition. This analysis includes: when the first load value is in the boundary region of the load adjustment range, taking the time of the first load value as the starting point of the second preset time window, determining whether the electro-hydrogen coupling system is in a stable load operation state within the second preset time window; if it is determined that the electro-hydrogen coupling system is in a stable load operation state within the second preset time window, determining that the load adjustment range of the electro-hydrogen coupling system meets the reset condition, and obtaining the analysis results; if it is determined that the electro-hydrogen coupling system is not in a stable load operation state within the second preset time window, determining that the load adjustment range of the electro-hydrogen coupling system does not meet the reset condition, and obtaining the analysis results.

[0017] In some embodiments of this application, when the analysis results indicate that the load adjustment interval meets the reset conditions, the load adjustment interval is reset based on the target load value of the electro-hydrogen coupling system to obtain the target load adjustment interval adapted to the electro-hydrogen coupling system. This includes: when the analysis results indicate that the load adjustment interval meets the reset conditions, determining the first load value at the end of the first preset time window as the target load value, and determining the target load value as the target reference value; and resetting the load adjustment interval based on the target reference value and the preset adjustment ratio coefficient to generate the target load adjustment interval.

[0018] In some embodiments of this application, when it is determined that the electro-hydrogen coupling system is in the target regulation mode, before obtaining the real-time load value of the electro-hydrogen coupling system, the method includes: in response to a mode switching command triggered by a user, determining the current regulation mode of the electro-hydrogen coupling system; if the current regulation mode is the initial regulation mode and the mode switching command indicates switching to the target regulation mode, performing a regulation mode switching operation based on the mode switching command to switch the electro-hydrogen coupling system from the initial regulation mode to the target regulation mode.

[0019] In some embodiments of this application, controlling the target device in the electro-hydrogen coupling system to adjust the load of the electro-hydrogen coupling system according to the target load adjustment range includes: obtaining the target real-time load value of the electro-hydrogen coupling system after resetting the load adjustment range; determining whether to trigger a load adjustment operation based on the target real-time load value and the target load adjustment range; and, if it is determined that a load adjustment operation is triggered, generating a load adjustment command based on the deviation between the target real-time load value and the range boundary value, so as to control the corresponding target device to adjust the load of the electro-hydrogen coupling system according to the load adjustment command, wherein the range boundary value includes the lower limit and the upper limit of the target load adjustment range.

[0020] In some embodiments of this application, determining whether to trigger a load adjustment operation based on a target real-time load value and a target load adjustment range includes: defining the target load adjustment range as the load operating range of the electro-hydrogen coupling system; determining to trigger a load adjustment operation when the target real-time load value is not within the load operating range; and determining not to trigger a load adjustment operation when the target real-time load value is within the load operating range.

[0021] Secondly, embodiments of this application provide a load regulating device for an electro-hydrogen coupling system, the device comprising:

[0022] The acquisition unit is used to acquire the real-time load value of the electro-hydrogen coupling system when it is determined that the electro-hydrogen coupling system is in the target regulation mode; The analysis unit is used to reset the load adjustment range of the electric-hydrogen coupling system based on the interval position of the real-time load value relative to the load adjustment range of the electric-hydrogen coupling system and the load operation status of the electric-hydrogen coupling system within a preset time window, so as to obtain the analysis results. The reset unit is used to reset the load adjustment range based on the target load value of the electro-hydrogen coupling system when the analysis results indicate that the load adjustment range meets the reset conditions, so as to obtain the target load adjustment range adapted to the electro-hydrogen coupling system. The regulating unit is used to control the target equipment in the electro-hydrogen coupling system to regulate the load of the electro-hydrogen coupling system according to the target load regulation range.

[0023] Thirdly, embodiments of this application provide an electronic device, including: a processor and a memory for storing a computer program capable of running on the processor, wherein, when the processor runs the computer program, it performs the method described in any embodiment of the first aspect.

[0024] Fourthly, embodiments of this application provide a non-transitory computer-readable storage medium storing computer instructions, wherein the computer instructions are used to cause a computer to perform the methods described in any embodiment of the first aspect.

[0026] This application provides a load regulation method for an electro-hydrogen coupling system. By analyzing the real-time load value of the electro-hydrogen coupling system in target regulation mode relative to the load regulation range of the system, and the load operation status of the system within a preset time window, the method resets the load regulation range. If the analysis indicates that the load regulation range meets the reset conditions, the method resets the load regulation range according to the target load value of the electro-hydrogen coupling system, obtaining a target load regulation range adapted to the system. Based on this target load regulation range, the method controls the target equipment in the electro-hydrogen coupling system to regulate the load. This method uses a load regulation range instead of a fixed setpoint to regulate the system load. Simultaneously, it automatically triggers a load regulation range reset mechanism based on the real-time load value change trend, always allowing the system load to fluctuate within a reasonable range. This avoids frequent system load adjustments, significantly reducing the number of operations on equipment such as electrolyzers, and lowering equipment wear and maintenance costs.

Detailed Implementation

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. The described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] It should be noted that the terms "system," "device," "unit," and / or "module" used in this application are methods of distinguishing different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they can be replaced by other expressions.

[0032] In the following text, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0033] With the continuous growth of installed capacity of renewable energy sources such as wind power and photovoltaics, hydrogen energy is playing an increasingly crucial role in energy systems due to its energy storage and cross-medium coupling characteristics. Electric-hydrogen coupling systems achieve the spatial and temporal transfer and balance of energy through water electrolysis (power-to-hydrogen) and fuel cell power generation (hydrogen-to-power) technologies. In electric-hydrogen control systems, load regulation is a key link in ensuring system power balance, operational stability, and energy utilization efficiency. Simultaneously, switching regulation modes (taking the switch from manual to automatic regulation mode as an example) is a critical and risky aspect of the load regulation process.

[0034] In related technologies, when an operator switches from manual to automatic adjustment mode, they typically use the load value at the time of switching as a fixed setpoint, and then use this fixed setpoint as the adjustment target to automatically adjust the system's load. However, because the actual system load fluctuates, this rigid setting forces the system to frequently make large adjustments to track a single fixed value. This not only exacerbates the wear and energy consumption of core equipment such as electrolytic cells and compressors, but may also cause system instability due to drastic power adjustments, creating a vicious cycle.

[0035] To address the problems in related technologies, this application proposes a load regulation method for an electro-hydrogen coupling system. By setting a load regulation range during regulation mode switching, instead of adjusting the system load at a fixed setpoint, the system load is allowed to fluctuate within a reasonable range, ensuring a smooth transition to the target regulation mode. Simultaneously, based on the position of the real-time load value within the load regulation range under the target regulation mode and the continuous trend of the real-time load value, a load regulation range reset mechanism is automatically triggered. This ensures that the system load regulation always adapts to the current actual operating conditions, always allowing the load to fluctuate within a reasonable range, avoiding frequent adjustments, greatly reducing the number of operations on equipment such as electrolyzers, and lowering equipment wear and maintenance costs.

[0036] The following section provides a detailed description of a load regulation method for an electro-hydrogen coupling system provided in this application, with reference to the accompanying drawings.

[0037] Figure 1 A flowchart illustrating a load regulation method for an electro-hydrogen coupling system provided in an embodiment of this application is shown. Figure 1 As shown, the load regulation method of the electro-hydrogen coupling system includes steps 101-104.

[0038] Step 101: If it is determined that the electro-hydrogen coupling system is in the target regulation mode, obtain the real-time load value of the electro-hydrogen coupling system.

[0039] In the embodiments of this application, the target adjustment mode specifically refers to the automatic adjustment mode of the electro-hydrogen coupling system. In this mode, the system automatically adjusts the system load according to the adjustment strategy without manual intervention.

[0040] Real-time load value refers to the actual operating load of the electro-hydrogen coupling system at the current moment. It is usually expressed in power and reflects the current power consumption or output level of the system.

[0041] Optionally, before obtaining the real-time load value of the electro-hydrogen coupling system (hereinafter referred to as the system), this application has already switched the system to the target regulation mode (i.e., automatic regulation mode). Specifically, in response to a mode switching command triggered by the user, the current regulation mode of the electro-hydrogen coupling system is determined; if the current regulation mode is the initial regulation mode and the mode switching command indicates switching to the target regulation mode, a regulation mode switching operation is performed based on the mode switching command to switch the electro-hydrogen coupling system from the initial regulation mode to the target regulation mode.

[0042] The initial adjustment mode refers to the manual adjustment mode. Users (operators) can issue mode switching commands, such as switching from "manual adjustment mode" to "automatic adjustment mode," through the equipment's human-machine interface, control panel, or physical buttons. Upon detecting this signal, the system switches from manual to automatic adjustment mode and establishes a load adjustment range based on the load value at the time of switching.

[0043] In automatic adjustment mode, the system load is kept within the load adjustment range by monitoring the real-time load value, rather than forcibly maintaining the system load at a single fixed load value.

[0044] Step 102: Based on the real-time load value relative to the load adjustment range of the electro-hydrogen coupling system and the load operation status of the electro-hydrogen coupling system within a preset time window, the load adjustment range of the electro-hydrogen coupling system is reset and analyzed to obtain the analysis results.

[0045] In the embodiments of this application, the load adjustment range is a load range formed by the load value corresponding to the system mode switching time and fluctuating by a certain percentage (such as 10%), which is used as the target operating range of the system load in the automatic adjustment mode.

[0046] The location of a load interval refers to the positional relationship of the real-time load value relative to the load adjustment interval, including being inside the interval or near the boundary of the interval.

[0047] The preset time window is a pre-defined time length used to observe and analyze the operating status of the system load within a specific time period, including a first preset time window (used to determine whether the system load is continuously at the boundary) and a second preset time window (used to determine whether the system load is stable).

[0048] Reset analysis is the process of determining whether the current load regulation interval needs to be updated or replaced. The analysis results are of two types: the load regulation interval meets the reset conditions, and the load regulation interval does not meet the reset conditions.

[0049] This application comprehensively judges whether the current load adjustment range is still suitable for the actual operating conditions of the system based on the position of the current real-time load value within the load adjustment range (e.g., whether it is located in the boundary area) and the load operation status of the system within a preset time window (e.g., whether the load is continuously at the boundary, whether the load fluctuation is stable). If it is not suitable, the load adjustment range needs to be reset.

[0050] Step 103: If the analysis results indicate that the load adjustment range meets the reset conditions, the load adjustment range is reset based on the target load value of the electro-hydrogen coupling system to obtain the target load adjustment range adapted to the electro-hydrogen coupling system.

[0051] In the embodiments of this application, the reset condition is the criterion for triggering the load adjustment range reset, including the load being continuously in the boundary area of ​​the load adjustment range and the system load operating state being stable.

[0052] The target load value is the load value used to construct a new load adjustment interval when the load adjustment interval meets the reset conditions. In this application, the real-time load value of the system at the end of the first preset time window is taken as the target load value.

[0053] This application uses the target load value as a benchmark to reconstruct a new load regulation range, replacing the original load regulation range, so as to control the system load to operate within the new load regulation range.

[0054] Step 104: Based on the target load adjustment range, control the target device in the electro-hydrogen coupling system to adjust the load of the electro-hydrogen coupling system.

[0055] In the embodiments of this application, the target device refers to the core device in the electro-hydrogen coupling system that can participate in load regulation, including but not limited to core devices such as electrolyzers and fuel cell compressors.

[0056] Specifically, this application uses the constructed target load adjustment range as the new load adjustment target and monitors the system load value in real time. When the real-time load value deviates from the target load adjustment range, a corresponding adjustment command (such as a load increase command or a load decrease command) is sent to the target equipment to bring the system load back within the target load adjustment range. When the actual load value is within the target load adjustment range, no load adjustment operation is triggered, and the current operating state of the equipment is maintained, thereby avoiding frequent adjustments.

[0057] In summary, the load regulation method for an electro-hydrogen coupling system proposed in this application involves obtaining the real-time load value of the electro-hydrogen coupling system when it is determined to be in the target regulation mode; resetting the load regulation range of the electro-hydrogen coupling system based on the position of the real-time load value relative to the load regulation range of the electro-hydrogen coupling system and the load operation status of the electro-hydrogen coupling system within a preset time window to obtain the analysis results; when the analysis results indicate that the load regulation range meets the reset conditions, resetting the load regulation range based on the target load value of the electro-hydrogen coupling system to obtain the target load regulation range adapted to the electro-hydrogen coupling system; and controlling the target equipment in the electro-hydrogen coupling system to regulate the load of the electro-hydrogen coupling system according to the target load regulation range. This method achieves load regulation of the system by replacing the fixed setpoint with the load regulation range, and automatically triggers the load regulation range reset mechanism according to the changing trend of the real-time load value, always allowing the system load to fluctuate within a reasonable range, thereby avoiding frequent system load adjustments, greatly reducing the number of operations of equipment such as electrolyzers, and reducing equipment wear and maintenance costs.

[0058] As one possible implementation method, Figure 2 A flowchart of a second load regulation method for an electro-hydrogen coupling system is shown. Based on the above embodiments, the load regulation range of the electro-hydrogen coupling system is reset and analyzed based on the interval position of the real-time load value relative to the load regulation range of the electro-hydrogen coupling system and the duration of the real-time load value within the interval position, to obtain the analysis results. This includes the following steps: Step 201: When it is determined that the electro-hydrogen coupling system is in the target regulation mode, obtain the switching load value when the electro-hydrogen coupling system switches to the target regulation mode, and determine the switching load value as the initial reference value.

[0059] In the embodiments of this application, the switching load value is the real-time load value of the system at the instant when the electro-hydrogen coupling system switches from the initial adjustment mode (such as manual adjustment mode) to the automatic adjustment mode (such as automatic adjustment mode).

[0060] Specifically, when the electro-hydrogen coupling system switches from manual to automatic adjustment mode, the system records the moment of the mode switch and obtains the real-time load value at that moment. This load value is used as the initial reference value to generate the initial load adjustment range. After the system mode switch, the system load is allowed to fluctuate within this initial load adjustment range. This ensures a smooth transition from manual to automatic adjustment mode.

[0061] Step 202: Based on the initial baseline value, construct the load regulation range of the electro-hydrogen coupling system.

[0062] In the embodiments of this application, after the system switches adjustment modes, the real-time load value L at the time of switching is... current Determined as the initial reference value L base And based on the initial baseline value L base And a preset adjustment ratio coefficient α, determine the upper limit value L of the initial adjustment range. high and the lower limit of the interval L low Based on the upper limit value L of the interval high and the lower limit of the interval L low Construct load adjustment range [L] low , L high ].

[0063] Specifically, using the initial reference value L base Centered on the target value, and using a preset adjustment ratio coefficient α, calculate the upper limit value L of the interval. high and the lower limit of the interval L low This establishes a load regulation range. Where L high = L base × (1 + α), L low= L base ×(1 - α). The default value of α is 0.1 (i.e., 10%, which can be configured according to actual needs and is not limited in the embodiments of this application).

[0064] In summary, this application achieves a smooth transition from manual to automatic adjustment mode by obtaining the switching load value when the system switches to the target adjustment mode and determining it as the initial reference value. Then, based on the initial reference value and the preset adjustment ratio coefficient, a load adjustment range is constructed. This allows the load adjustment range to replace a single fixed setpoint when switching from manual to automatic adjustment mode. In automatic adjustment mode, the system load no longer forcibly tracks a fixed value, but fluctuates autonomously within an allowable range, thus avoiding frequent and large adjustments caused by rigid setpoints.

[0065] As one possible implementation method, Figure 3 A flowchart of a third type of load regulation method for an electro-hydrogen coupling system is shown. Figure 3 based on Figure 1 The illustrated embodiment further defines step 102, in Figure 3 In the illustrated embodiment, step 102 includes steps 301, 302, 303, 304, 305, 306, and 307, as follows: Figure 3 As shown, the method includes the following steps: Step 301: Analyze the position of the real-time load value relative to the load adjustment range of the electro-hydrogen coupling system to determine whether the real-time load value is in the boundary region of the load adjustment range.

[0066] In the embodiments of this application, the boundary region is a sub-interval located near the boundary of the load adjustment interval, used to determine whether the load is approaching and has reached the upper or lower limit of the interval. The boundary region includes an upper boundary region and a lower boundary region.

[0067] Optionally, the boundary region of the load adjustment range can be determined based on the load adjustment range and the boundary triggering coefficient.

[0068] The boundary trigger coefficient is a preset parameter used to define the range of the boundary region. Its default value is 98% (i.e., 0.98, but user-configurable), and its typical range is 95%-100%, which is not limited in the embodiments of this application. This coefficient determines how close the load needs to be to the boundary region.

[0069] Optionally, the upper boundary region is determined based on the boundary triggering coefficient and the upper limit of the load adjustment range, combined with the first boundary division rule; the lower boundary region is determined based on the boundary triggering coefficient and the lower limit of the load adjustment range, combined with the second boundary division rule.

[0070] The first boundary division rule refers to the calculation rule for the upper boundary region, starting from the upper boundary (the upper limit of the interval) and combining it with the boundary triggering coefficient β. Specifically, it is: taking the upper limit of the interval as the endpoint and offsetting downwards by a proportion of (1-β), the upper boundary interval [L] is formed. high × β, L high When β is 98%, the upper boundary region is [L]. high × 0.98, L high ], where L high × 0.98 indicates a 2% narrowing from the upper limit of the interval downwards.

[0071] The second boundary division rule refers to the calculation rule for the lower boundary region, starting from the lower boundary (lower limit of the interval) and combining it with the boundary triggering coefficient β. Specifically, it is as follows: starting from the lower limit of the interval, the lower boundary interval [L] is formed by shifting upwards by a proportion of (1-β). low , L low + L low × (1-β)]. When β is 98%, the lower boundary region is [L]. low , L low [× 1.02], where L low × 1.02 indicates an upward expansion of 2% from the lower limit of the interval. The offset magnitude of both the upper and lower boundary regions is 2%, exhibiting symmetry.

[0072] When the real-time load value falls within the upper or lower boundary area, it is determined that the real-time load value is in the boundary area of ​​the load adjustment range.

[0073] Step 302: If it is determined that the real-time load value is in the boundary region, take the time when the real-time load value is located as the starting point of the first preset time window, and obtain the first load value of the electro-hydrogen coupling system corresponding to the end time of the first preset time window.

[0074] In the embodiments of this application, a timer is started when the real-time load value is in the boundary region. The duration of the timer (i.e., the first preset time window) T set This is a configurable parameter, set to 1 minute by default, and is not limited in the embodiments of this application.

[0075] Specifically, when the system detects the real-time load value L real Approaching and reaching the upper limit L of the load adjustment range high Or lower limit L low When the threshold value is reached or exceeded (e.g., 95% to 100% of the boundary value), the current moment is recorded as the start of the window, and the timer is started. When the timer duration reaches the first preset time window (e.g., 1 minute), the system load value at that moment is read and recorded as the first load value.

[0076] Step 303: Based on the load adjustment range, determine whether the first load value is within the boundary area of ​​the load adjustment range.

[0077] In the embodiments of this application, the obtained first load value is compared with the boundary area of ​​the load adjustment range to determine whether the first load value is still within the boundary area. If it is, it indicates that the load continues to be near the boundary; if it is not, it indicates that the load has left the boundary area.

[0078] Specifically, the timer reaches the set duration T. set Then, based on the magnitude of the first load value, it is determined whether the first load value still remains near the boundary (for example, the first load value is still within the range [L]). high × 0.98, L high ] or [L low , L low [×1.02] (within).

[0079] Step 304: If the first load value is not in the boundary region of the load adjustment range, determine that the load adjustment range of the electro-hydrogen coupling system does not meet the reset condition, so as to maintain the load adjustment range unchanged.

[0080] In the embodiments of this application, when the first load value is not in the boundary region, it indicates that although the system load touched the boundary at a certain moment, it had already left the boundary region by the end of the first preset time window, which is a short-term fluctuation rather than a continuous trend. In this case, it is determined that the load adjustment range does not meet the reset condition, the current load adjustment range is maintained unchanged, the timer is reset, and monitoring continues.

[0081] Step 305: When the first load value is in the boundary region of the load adjustment range, take the time when the first load value is located as the starting point of the second preset time window, and determine whether the electro-hydrogen coupling system is in a stable load operation state within the second preset time window.

[0082] In the embodiments of this application, when the first load value is in the boundary region of the load adjustment range, it indicates that the system load has been continuously near the boundary for a first preset time window (e.g., 1 minute). At this time, it is necessary to further determine whether the load is stable in order to confirm that this boundary state is a continuous trend rather than a short-term, unstable fluctuation.

[0083] Optionally, the starting point of the second preset time window is taken as the time when the first load value is located, and at least one real-time load value of the electro-hydrogen coupling system within the second preset time window is obtained; based on the at least one real-time load value, the load fluctuation amplitude of the electro-hydrogen coupling system is determined; based on the load fluctuation amplitude, it is determined whether the electro-hydrogen coupling system is in a stable load operation state.

[0084] The second preset time window is a duration window used to determine whether the system load is in a stable operating state, denoted as T. stable T stable The default value is 30 seconds, and the typical value range is from 10 seconds to 2 minutes. It can be configured according to actual needs and is not limited in the embodiments of this application.

[0085] Load fluctuation amplitude refers to the degree of change in the load value of the electro-hydrogen coupling system within a second preset time window, used to quantify the severity of load fluctuations within that time window. Specifically, it can be characterized by the difference between the maximum and minimum system load values ​​within the window, the standard deviation of the load data, or the relative percentage of the fluctuation value to a baseline value. This is not limited in the embodiments of this application.

[0086] Optionally, determining whether the electro-hydrogen coupling system is in a stable load operation state based on the load fluctuation amplitude includes: determining whether the electro-hydrogen coupling system is in a stable load operation state based on the load fluctuation amplitude and a preset stability threshold.

[0087] The preset stability threshold, denoted as Δ, is a critical value used to determine whether the system load is in a stable operating state. This threshold can be a relative value (e.g., ±1%L). base () or a fixed absolute power value. The default value for Δ is ±1%L. base The typical value range is ±0.5%L. base Up to ±3%L base The configuration can be adjusted according to the actual operating conditions of the system, and is not limited in the embodiments of this application.

[0088] Optionally, determining whether the electro-hydrogen coupling system is in a stable load operation state based on the load fluctuation amplitude and the preset stability threshold includes: determining that the electro-hydrogen coupling system is not in a stable load operation state when the load fluctuation amplitude is greater than or equal to the preset stability threshold; and determining that the electro-hydrogen coupling system is in a stable load operation state when the load fluctuation amplitude is less than the preset stability threshold.

[0089] Specifically, the condition for determining whether the electro-hydrogen coupling system is in a stable load operation state is: a configurable time window (i.e., the second preset time window) T before the time of the first load value. stable If the fluctuation range of the real-time load of the system is always less than the preset stability threshold Δ within 30 seconds (for example), it indicates that the electro-hydrogen coupling system is in a stable load operation state; if the fluctuation range of the real-time load of the system is always less than the preset stability threshold Δ, it indicates that the electro-hydrogen coupling system is not in a stable load operation state.

[0090] Step 306: If the electro-hydrogen coupling system is in a stable load operation state within the second preset time window, determine that the load adjustment range of the electro-hydrogen coupling system meets the reset condition, and obtain the analysis results.

[0091] Step 307: If it is determined that the electro-hydrogen coupling system is not in a stable load operation state within the second preset time window, then the load adjustment range of the electro-hydrogen coupling system does not meet the reset condition, and the analysis results are obtained.

[0092] In the embodiments of this application, when it is determined that the electro-hydrogen coupling system is in a stable load operation state within the second preset time window, it indicates that the system has simultaneously met the following two adjustment range reset conditions: the system load has been continuously in the boundary region of the load adjustment range for up to the first preset time window (indicating that the load does not leave immediately after briefly touching the boundary, but has a continuous tendency to approach the boundary); and the system load fluctuation amplitude is less than the preset stability threshold within the second preset time window (indicating that the load is running smoothly without violent oscillations, and the current boundary state is a stable and continuous trend). At this time, it is necessary to reset the system's load adjustment range to adapt the system to the current actual operating conditions.

[0093] Conversely, if the electro-hydrogen coupling system is not in a stable load operation state within the second preset time window (i.e., the load fluctuation amplitude is greater than or equal to the preset stability threshold), then even if the load is in the boundary area, it is determined that the load adjustment range does not meet the reset conditions, so the current load adjustment range remains unchanged and the range reset operation is not triggered.

[0094] In summary, this application constructs a complete load adjustment range reset analysis mechanism: first, it determines whether the system's real-time load is continuously within the boundary region of the load adjustment range and whether the system's load fluctuations are stable over a certain period. If both conditions are met, the load adjustment range needs to be reset; otherwise, it does not. Through a three-stage progressive judgment logic of boundary region determination, persistence verification, and stability verification, this application can accurately identify the continuous trend and short-term fluctuations of the load, ensuring that the range reset is triggered only when the load is stably and continuously within the boundary region. This effectively avoids erroneous resets and provides a reliable decision-making basis for generating a target load adjustment range adapted to the current operating conditions.

[0095] As one possible implementation method, Figure 4 A flowchart of the fourth load regulation method for an electro-hydrogen coupling system is shown. Figure 4 based on Figure 1 The illustrated embodiment further defines steps 103 and 104. Figure 4 In the illustrated embodiment, step 103 includes steps 401 and 402, and step 104 includes steps 403, 404, and 405, as follows. Figure 4 As shown, the method includes the following steps: Step 401: If the analysis results indicate that the load adjustment interval meets the reset conditions, determine the first load value at the end of the first preset time window as the target load value, and set the target load value as the target reference value.

[0096] Step 402: Based on the target benchmark value and the preset adjustment ratio coefficient, the load adjustment range is reset to generate the target load adjustment range.

[0097] In the embodiments of this application, when the load adjustment range of the system meets the reset condition, the real-time load value that is currently in a stable state (i.e., the first load value, also known as the target load value) is established as the new reference load value L. base_new Using this new benchmark as the center, the upper and lower limits of the adjustment range are recalculated according to the preset proportional coefficient α to generate a new load adjustment range (i.e., the target load adjustment range) [L]. low_new , L high_new The system will adjust the load with the new adjustment range as the target.

[0098] Among them, L high_new = L base_new × (1 + α), L low_new = L base_new × (1 - α).

[0099] Step 403: Obtain the target real-time load value of the electro-hydrogen coupling system after resetting the load adjustment range.

[0100] Step 404: Based on the target real-time load value and the target load adjustment range, determine whether to trigger a load adjustment operation.

[0101] In the embodiments of this application, after the system load adjustment range is reset, the real-time load value of the system (i.e., the target real-time load value) continues to be monitored, and the system decides whether to trigger a load adjustment operation based on the target real-time load value and the target load adjustment range.

[0102] Optionally, the target load adjustment range is defined as the load operating range of the electro-hydrogen coupling system; if the target real-time load value is not within the load operating range, load adjustment operation is triggered; if the target real-time load value is within the load operating range, load adjustment operation is not triggered.

[0103] Specifically, if the target real-time load value is within the target load adjustment range, it indicates that the current actual load value of the system is already within the allowable range of the new range, and no immediate adjustment is required. In this case, the system does not trigger load adjustment operations, the target equipment maintains its current operating state, and load monitoring continues.

[0104] If the target real-time load value is not within the target load adjustment range, it indicates that the current actual load value of the system has deviated from the new range (i.e., below the lower limit of the range or above the upper limit of the range), and immediate adjustment is required to bring it back to the target load adjustment range. At this time, the system will trigger a load adjustment operation.

[0105] Step 405: If it is determined that a load adjustment operation has been triggered, a load adjustment command is generated based on the deviation between the target real-time load value and the interval boundary value, so as to control the corresponding target equipment to adjust the load of the electro-hydrogen coupling system according to the load adjustment command.

[0106] In the embodiments of this application, the load adjustment command is a control command sent by the system to the target device (such as an electrolyzer, fuel cell, compressor, etc.), which includes the adjustment direction (increase or decrease load) and the adjustment amount (such as power increase or decrease value) to instruct the target device to perform the corresponding power adjustment operation.

[0107] The interval boundary values ​​include the lower limit and upper limit of the target load adjustment interval.

[0108] Specifically, the first step is to determine the positional relationship between the target real-time load value and the target load adjustment range: if the target real-time load value is lower than the lower limit of the range, it indicates that the system load is too low and load increase adjustment needs to be performed; if the target real-time load value is higher than the upper limit of the range, it indicates that the system load is too high and load decrease adjustment needs to be performed.

[0109] Then, based on the direction of deviation, calculate the deviation between the target real-time load value and the corresponding interval boundary value: For load increase regulation: Deviation = Lower limit of the interval - Target real-time load value; For load decrease regulation: Deviation = Target real-time load value - Upper limit of the interval. The deviation reflects the magnitude of the current load's deviation from the target interval boundary. The larger the deviation, the more severe the load deviation, and usually a larger adjustment range is required.

[0110] Finally, based on the calculated deviation and combined with the preset adjustment strategy, specific load adjustment commands are generated. The generation of adjustment commands can employ any one or more of the following methods: Direct command: The target load value is directly set to a target value within the target adjustment range of the zone, generating a set value command (applicable to scenarios with high adjustment accuracy requirements and strong equipment response capabilities).

[0111] Incremental command: Generate power increment values ​​(such as "increase X kW", "decrease Y%") according to the deviation amount proportionally or by a preset step size (for scenarios that require smooth adjustment and avoid shock).

[0112] Step-by-step instructions: When the deviation is large, the adjustment is made in multiple steps. For example, an adjustment instruction of a fixed step size is sent each time to prevent large adjustments from causing system oscillations.

[0113] The generated load adjustment command is sent to the corresponding target device (such as an electrolyzer or fuel cell). After receiving the command, the target device adjusts its operating power according to the command requirements. For example, an electrolyzer changes the system's electrical load by increasing or decreasing its input power; a fuel cell changes the system's power generation load by increasing or decreasing its output power.

[0114] After sending the adjustment command, continue to monitor the target real-time load value of the system and evaluate the adjustment effect. If the target real-time load value still has not returned to the target load adjustment range, repeat the above process for continuous adjustment until the system load stabilizes within the target load adjustment range.

[0115] In summary, this application achieves adaptive reset of the original load regulation range by reconstructing the range using the target load value as the new benchmark when the load regulation range meets the reset conditions. After reset, the system's target real-time load value is acquired and compared with the target load regulation range to determine whether load regulation operation needs to be triggered. If triggering is required, a load regulation command is generated based on the deviation between the target real-time load value and the range boundary value, controlling the target equipment such as the electrolyzer or fuel cell to perform corresponding power adjustments, thereby ensuring that the system load always remains within the target load regulation range. This application, through a closed-loop control mechanism of range reset and load regulation control, achieves dynamic adaptive shifting of the load regulation range, effectively solving the problem of frequent and large-scale adjustments caused by a single fixed setpoint in related technologies, and improving the stability and economy of the electro-hydrogen coupling system.

[0116] Furthermore, to help better understand the load regulation method for the electro-hydrogen coupling system provided in this application, such as... Figure 5 As shown, Figure 5 This is a schematic flowchart illustrating a specific load regulation method for an electro-hydrogen coupling system provided in an embodiment of this application.

[0117] Reference Figure 5 After system startup, the first step is to determine whether the electro-hydrogen coupling system is transitioning from manual control mode (i.e., manual adjustment mode) to automatic control mode (i.e., automatic adjustment mode). When a mode switch is detected, the current real-time load value L at the time of the switch is used. current The initial reference value L base Based on the preset adjustment ratio coefficient, the load adjustment range [L] is calculated and generated. low , L_ high Subsequently, the system maintains the real-time load value L. realWithin this initial load adjustment range, the system's real-time load value Lreal is continuously monitored, and L is determined. real Whether it has reached the vicinity of the boundary of the load adjustment range (i.e., whether it falls into the upper or lower boundary area). If L real If it does not reach the vicinity of the boundary, continue monitoring; if L real Once the boundary is neared, a timer is started, with a preset duration of T. set (i.e., the first preset time window). The timer reaches T. set Then, it is determined whether the current real-time load value (i.e., the first load value) is still near the boundary and in a stable operating state. If the determination result is no (i.e., the load has left the vicinity of the boundary or is fluctuating unstable), the timer is reset, the original load adjustment range remains unchanged, and monitoring continues; if the determination result is yes (i.e., the load continues to be stably near the boundary), the current real-time load value is used as the new reference value L. base_new A new load adjustment range is recalculated and generated, and this new range is used as the target for subsequent automatic adjustment, continuously monitoring the system load and adjustment.
