Description

Technical Field

[0001] The present application relates to the field of hydrogen energy storage technology, and in particular to a methanol hydrogen fuel cell power generation and solar energy integrated power supply system and a control method thereof. Background Art

[0002] At present, with the increasing global demand for clean energy, solar energy and hydrogen energy as two important renewable energy sources have received widespread attention, especially for application areas that require 24-hour uninterrupted power supply, such as cruise ships and ferries, which need to ensure the continuous operation of various electrical equipment on board (such as navigation instruments, communication devices, and air-conditioning systems) during voyage.

[0003] Existing battery technology cannot sustain high-power electricity consumption for a long time, and the use of fuel engines will increase operating costs and environmental pollution risks. If an emergency occurs during navigation, such as fuel exhaustion, there may be a risk of power outages. The power supply system based on renewable energy such as solar energy and hydrogen energy still has some shortcomings in practical applications: whether it is based on a single energy source (such as solar energy alone) or a hybrid energy system, when faced with changes in natural conditions (such as night or cloudy days) and sudden increases in load, it may encounter the challenge of unstable power supply and is difficult to meet complex and changing workload requirements. In particular, overload may occur during peak hours, causing power outages. Therefore, the existing power supply system generally has the defects of unstable power supply and low energy utilization efficiency, and there is room for improvement. Summary of the invention

[0004] In order to improve the power supply stability of the power supply system and enhance the energy utilization efficiency, the present application provides a methanol hydrogen fuel cell power generation and solar energy integrated power supply system and a control method thereof.

[0005] In the first aspect, the invention objective of the present application is achieved by adopting the following technical solutions: The methanol hydrogen fuel cell power generation and solar energy integrated power supply system includes: an energy management mechanism, a solar power generation device, a battery energy storage device, and multiple methanol hydrogen battery power generation devices; The energy management mechanism obtains the power supply demand parameters of the target electrical equipment, and based on the current power storage status of the solar power generation device, the multiple methanol hydrogen battery power generation devices and the battery energy storage device, controls each power supply device to start and stop supplying power to supply power to the target electrical equipment; When the methanol-hydrogen battery power generation device is supplying power, the energy management mechanism switches different methanol-hydrogen battery power generation devices or different combinations of methanol-hydrogen battery power generation devices to supply power based on a preset hydrogen energy power generation management strategy and in combination with the current electrical energy storage status of each methanol-hydrogen battery power generation device. The preset hydrogen energy power generation management strategy is used to manage the simultaneous power supply status and power supply parameter ratio of multiple methanol-hydrogen battery power generation devices.

[0006] By adopting the above technical scheme, the target power-consuming equipment includes hydrogen fuel cell vehicle refueling stations, electrical loads inside and around buildings, data centers and other high-power consumption facilities. In order to achieve stable power supply to the target power-consuming equipment and optimize energy utilization efficiency, the present application adopts a collaborative comprehensive management method of intelligent power supply control, power supply mode priority management (such as giving priority to solar power supply, power supply to methanol hydrogen battery power generation device, and finally power supply to battery energy storage device), and hydrogen power generation management strategy. Specifically, after analyzing the power supply demand parameters of the target power-consuming equipment, an evaluation is first performed based on the current power storage status of the solar power generation device, multiple methanol hydrogen battery power generation devices and battery energy storage devices. According to the above evaluation results, each power supply device is dynamically turned on or off to meet the needs of the target power-consuming equipment. If solar power supply meets the power demand of the target power-consuming equipment, solar power supply is used first and only. When solar energy does not meet the power demand, the methanol hydrogen battery power generation device or the battery energy storage device can be controlled (when the methanol hydrogen battery power generation device also cannot meet the power supply demand). By combining solar power generation with hydrogen energy storage, solar energy can be fully utilized during the day, and the excess energy can be used to produce hydrogen and stored in the methanol hydrogen battery power generation device; at night or other times when light is insufficient, hydrogen power generation is relied upon to provide stable power support, which not only improves the self-sufficiency rate of the overall energy system, but also reduces dependence on the external power grid; further, when the methanol hydrogen battery power generation device is supplying power, the energy management agency decides how to switch different methanol hydrogen battery power generation devices to supply power based on a preset hydrogen energy power generation management strategy, so as to select the optimal power supply combination for power supply, and ensure the continuity and stability of power output, that is, according to different time periods or load changes, the power supply parameter ratio between each methanol hydrogen battery power generation device is flexibly adjusted. Since there are multiple methanol hydrogen battery power generation devices, even if a device fails or the energy storage level is low, it can immediately switch to other normally operating devices to continue supplying power, avoiding the risk of power outages caused by failure of a single power source point, thereby enhancing the reliability and safety of the power supply system.

[0007] In a preferred example of the present application, when the methanol hydrogen battery power generation device supplies power, the energy management mechanism switches different methanol hydrogen battery power generation devices or different methanol hydrogen battery power generation device combinations to supply power according to a preset hydrogen energy power generation management strategy and in combination with the current electric energy storage status of each methanol hydrogen battery power generation device, specifically including: The energy management mechanism acquires the current electric energy storage data of a plurality of methanol hydrogen battery power generation devices in real time and associates the corresponding device identifications; Send different energy storage data to the judgment model to identify and determine the current energy storage level of each methanol hydrogen battery power generation device, and determine the methanol hydrogen battery power generation device with sufficient energy storage; The energy management agency selects the best methanol hydrogen battery power generation device for power supply switching according to the energy storage level evaluation result; when the energy storage level of a methanol hydrogen battery power generation device is lower than the set threshold, it automatically switches to the methanol hydrogen battery power generation device with sufficient energy storage to continue power supply; When the energy levels of all methanol hydrogen battery power generation devices are lower than the corresponding set thresholds, a battery energy storage processing prompt instruction is triggered based on the device identification.

[0008] By adopting the above technical scheme, the energy storage level changes of multiple methanol hydrogen battery power generation devices are monitored in real time to achieve accurate grasp of the energy storage status of multiple methanol hydrogen battery power generation devices, reduce the occurrence of power supply interruptions caused by insufficient energy storage, and when the energy storage level of a methanol hydrogen battery power generation device is lower than the set threshold, it is automatically switched to the methanol hydrogen battery power generation device with sufficient energy storage to continue supplying power, thereby ensuring the continuity and stability of power supply; the hydrogen energy power generation management strategy of the present invention selects the optimal methanol hydrogen battery power generation device for power supply switching based on the energy storage level evaluation result, ensuring that each power supply is provided by the most suitable energy storage device at the moment, thereby maximizing energy utilization efficiency. The hydrogen energy power generation management strategy supports dynamic adjustment of power supply arrangements based on real-time load changes and energy storage conditions, further improving the response speed and adaptability of the system and reducing unnecessary energy waste.

[0009] In a preferred example of the present application: the hydrogen power generation management strategy is a dynamic control strategy, and the method for obtaining the hydrogen power generation management strategy includes: The energy management mechanism monitors the real-time power consumption of the target electrical equipment, records the power demand at each moment and classifies the loads according to the load priority, and obtains load change information and corresponding load priority; Creating multiple power supply time periods according to the power consumption time periods in the multiple load change information and the demand patterns of loads with different priorities; According to the multiple power supply time periods, the multiple load change information is classified and processed to obtain multiple power supply task sets, each of which includes a power demand forecast and a corresponding power supply arrangement within a specific time period; A hydrogen power generation management strategy is generated based on the multiple power supply task sets and the current energy storage levels of the multiple methanol hydrogen battery power generation devices.

[0010] By adopting the above technical scheme, in order to improve the response speed, adaptability and energy utilization efficiency of the integrated power supply system of methanol hydrogen fuel cell power generation and solar energy, the present application monitors the real-time power consumption of the target power-consuming equipment through the energy management mechanism, classifies the loads according to the load priority, and generates a hydrogen power generation management strategy; specifically, according to the power consumption period in multiple load change information and the demand pattern of loads with different priorities, multiple power supply periods are created, allowing the system to flexibly adjust the power supply plan according to actual needs, and by classifying and processing multiple load change information, multiple power supply task sets are obtained, each of which contains a power demand forecast and corresponding power supply arrangement within a specific time period. Through accurate classification, energy resources can be allocated more effectively. Based on multiple power supply task sets and the current energy storage level of multiple methanol hydrogen battery power generation devices, a hydrogen power generation management strategy is generated, which not only takes into account the load demand, but also combines the status of the energy storage device to achieve optimal energy allocation; through load priority classification, the system can give priority to meeting the needs of critical loads when resources are limited, thereby improving the reliability and safety of the entire system.

[0011] In a preferred example of the present application, when multiple power supply periods are created according to the power consumption periods in the multiple load change information and the demand patterns of loads with different priorities, the method includes: Determining a plurality of different first load change information pieces according to the power demand cycles in the plurality of load change information pieces; According to a plurality of different first load change information and preset fixed power supply durations, combined with the current energy storage levels of the plurality of methanol hydrogen battery power generation devices, a plurality of initial power supply time periods are correspondingly created, and the maximum power supply time of each initial power supply time period satisfies the sum of the power demand cycle of the first load change information and the fixed power supply duration; Based on the power demand cycle of the currently processed load change information, the power supply period to be combined and the corresponding power supply task set are determined, and the currently processed load change information is merged into the power supply task set corresponding to the power supply period to be combined.

[0012] By adopting the above technical solution, the first load change information is identified and processed, and the system can quickly respond to new load demands, ensuring that each new load change can be promptly included in the power supply plan, and creating an initial power supply period based on the first load change information and the fixed power supply duration, so that each power supply period can accurately match the actual load demand, avoiding excessive or insufficient power supply. At the same time, the power supply period and task set are dynamically adjusted according to the currently processed load change information to ensure that resource allocation always meets actual needs, further improving energy utilization efficiency. When a power supply period ends or needs to be adjusted, the system can quickly find a suitable power supply period to be combined and merge the new load change information into it, ensuring the continuity of power supply. The present application determines the power supply period to be combined based on the power demand cycle of the currently processed load change information. The system can flexibly respond to new load demands while maintaining the existing power supply arrangement, thereby enhancing the adaptability of the system.

[0013] In a preferred example of the present application: the energy management mechanism further comprises: determining the currently processed load change information and the created power supply period according to the power demand cycle in the multiple load change information, the created power supply period is associated with the power supply task set, and the created power supply period includes an expandable power supply period; If new load change information appears during the created power supply period, determine whether the new load change information is consistent with the existing power supply period: If the power demand cycle of the currently processed load change information is within the created power supply period, the currently processed load change information is merged into the corresponding power supply task set; If the power demand cycle of the currently processed load change information is not within the created power supply period, but within the extendable period of the created power supply period, then the power supply time range and the extendable period time range of the power supply period are updated with the power demand cycle of the current load change information, and the currently processed load change information is merged into the updated power supply period; If the power demand cycle of the currently processed load change information is not within the created power supply period and cannot be merged with the created power supply period, a new power supply period and its corresponding power supply task set are created based on the power demand cycle of the currently processed load change information, and the currently processed load change information is merged into the new power supply period.

[0014] By adopting the above technical solution, in order to improve the ability to quickly respond to dynamic load changes and enable the system to maintain efficient operation under various working conditions, the present application continuously updates and adjusts the power supply period and task set, and performs self-optimization based on historical data and real-time feedback to ensure long-term stable operation. By continuously monitoring the energy storage level and load demand, an early warning can be issued when the energy storage level approaches the critical value, and preventive measures can be taken, such as starting the backup energy storage device or adjusting non-critical loads. Through precise power supply period management and flexible task set adjustment, the power supply at the user end is more stable and smooth, reducing the inconvenience caused by unstable power supply and improving user experience. For new load change information that cannot be merged with the existing power supply period, the system will create a new power supply period and its corresponding power supply task set based on its power demand cycle to ensure that each load can get reasonable resource allocation.

[0015] In a preferred example of the present application: the extendable period of the power supply period includes: The expandable power supply period is expanded into an increased power supply period or a reduced power supply period according to a preset dynamic adjustment duration; the time range of the increased power supply period is calculated based on the time increase of the next load change information to be processed, and the time range of the reduced power supply period is calculated based on the time reduction of the next load change information to be processed; The preset dynamic adjustment duration is obtained by association mapping based on the device identification of the methanol hydrogen battery power generation device, and is optimized and adjusted based on the current energy storage level of the methanol hydrogen battery power generation device.

[0016] By adopting the above technical solution, the time range of the increased power supply period and the reduced power supply period is calculated based on the specific load change information, ensuring that each adjustment is to better match the actual load demand and avoiding unnecessary energy waste. By optimizing and adjusting based on the current energy storage level of the methanol hydrogen battery power generation device, the system can extend the power supply period when the energy storage is sufficient and shorten the power supply period when the energy storage is insufficient, thereby maximizing the use of existing energy storage resources and improving the overall energy utilization efficiency. When the power supply period needs to be extended, the system can smoothly incorporate the new load change information into the existing power supply plan to ensure the continuity of power supply.

[0017] In the second aspect, the invention objective of the present application is achieved by adopting the following technical solutions: A control method based on methanol hydrogen fuel cell power generation and solar energy integrated power supply is applied to the methanol hydrogen fuel cell power generation and solar energy integrated power supply system as described above, and the method comprises: Obtaining power supply demand parameters of the target electrical equipment, and obtaining the current power storage status of the solar power generation device, the plurality of methanol hydrogen battery power generation devices and the battery energy storage device, and controlling each power supply device to start and stop power supply to supply power to the target electrical equipment; When the methanol-hydrogen battery power generation device is supplying power, the energy management mechanism switches different methanol-hydrogen battery power generation devices or different combinations of methanol-hydrogen battery power generation devices to supply power based on a preset hydrogen energy power generation management strategy and in combination with the current electrical energy storage status of each methanol-hydrogen battery power generation device. The preset hydrogen energy power generation management strategy is used to manage the simultaneous power supply status and power supply parameter ratio of multiple methanol-hydrogen battery power generation devices.

[0018] By adopting the above technical solutions, the energy management agency can flexibly switch different methanol hydrogen battery power generation devices or combinations according to the preset hydrogen power generation management strategy and the current energy storage status, thereby enhancing the adaptability and flexibility of the system. By accurately evaluating the energy storage level and optimizing the power supply parameter ratio, the existing energy storage resources can be maximized and energy utilization efficiency can be improved.

[0019] In a preferred example of the present application: the method further includes: When multiple power supply time periods are created, correspondingly recording the creation time of the multiple power supply time periods; Determining whether the creation time of the plurality of power supply time periods satisfies a preset timeout period; If it is identified that the creation time of a certain power supply period meets the preset timeout period, the power supply period is finally confirmed and the power supply switching control instruction is triggered.

[0020] By adopting the above technical solution, according to the preset timeout time, the system can quickly identify the power supply period that has not been completed beyond the preset time, and take corresponding measures to avoid power supply interruption or instability caused by delays. When the power supply period reaches the preset timeout time, the system will make a final confirmation and trigger the power supply switching control instruction to ensure the reasonable allocation and efficient utilization of resources and avoid occupying unnecessary energy storage devices for a long time; once the power supply period timeout is identified, the system immediately triggers the power supply switching control instruction to ensure that the new power supply arrangement can be quickly replaced to maintain the continuity of power supply.

[0021] In the third aspect, the invention objective of the present application is achieved by adopting the following technical solutions: A computer device comprises a memory, a processor and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the control method based on methanol hydrogen fuel cell power generation and solar energy integrated power supply are implemented.

[0022] In a fourth aspect, the invention objective of the present application is achieved by adopting the following technical solutions: A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of the control method based on the integrated power supply of methanol hydrogen fuel cell power generation and solar energy.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. After analyzing the power supply demand parameters of the target power-consuming equipment, first evaluate the current power storage status of the solar power generation device, multiple methanol hydrogen battery power generation devices and battery energy storage devices. According to the above evaluation results, dynamically open or shut down each power supply device to meet the needs of the target power-consuming equipment. If solar power supply meets the power demand of the target power-consuming equipment, solar power supply is used first and only. When solar power does not meet the power demand, the methanol hydrogen battery power generation device or the battery energy storage device (when the methanol hydrogen battery power generation device also cannot meet the power supply demand) can be controlled to supply power. By combining solar power generation with hydrogen energy storage, solar energy can be fully utilized during the day, and the excess energy can be used to produce hydrogen and stored in the methanol hydrogen battery power generation device; at night or other times when there is insufficient light, hydrogen power generation is relied on to provide stable power support, which not only improves the self-sufficiency rate of the overall energy system, but also reduces dependence on the external power grid; 2. In order to improve the ability to respond quickly to dynamic load changes and keep the system running efficiently under various working conditions, this application continuously updates and adjusts the power supply period and task set, performs self-optimization based on historical data and real-time feedback, and ensures long-term stable operation. Through continuous monitoring of energy storage levels and load demand, early warnings can be issued when the energy storage level approaches the critical value, and preventive measures can be taken, such as starting backup energy storage devices or adjusting non-critical loads. Through precise power supply period management and flexible task set adjustment, the power supply at the user end is more stable and smooth, reducing the inconvenience caused by unstable power supply and improving user experience; 3. According to the preset timeout time, the system can quickly identify the power supply period that has not been completed beyond the scheduled time, and take corresponding measures to avoid power supply interruption or instability caused by delays. When the power supply period reaches the preset timeout time, the system will make a final confirmation and trigger the power supply switching control instruction to ensure the rational allocation and efficient use of resources and avoid occupying unnecessary energy storage devices for a long time; once the power supply period timeout is identified, the system will immediately trigger the power supply switching control instruction.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings.

[0026] In one embodiment, if Figure 1 and Figure 2 As shown, the present application discloses a methanol hydrogen fuel cell power generation and solar energy integrated power supply system, which includes an energy management mechanism, a solar power generation device, a battery energy storage device, and multiple methanol hydrogen battery power generation devices. The solar power generation device refers to a device that generates solar power based on a solar panel assembly, and the battery energy storage device is a device based on an energy storage battery. The methanol hydrogen battery power generation device is a power generation device based on methanol water fuel that is reformed to produce rich hydrogen and purified by palladium or pressure swing adsorption to obtain more than 99.975% pure hydrogen, which is then generated through a hydrogen fuel cell (a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy), and finally outputs through power distribution.

[0027] The energy management agency obtains the power supply demand parameters of the target electrical equipment, and based on the current electric energy storage status of the solar power generation device, multiple methanol hydrogen battery power generation devices and the battery energy storage device, controls each power supply device to start and stop supplying power to supply power to the target electrical equipment; when the methanol hydrogen battery power generation device is supplying power, the energy management agency switches different methanol hydrogen battery power generation devices or different combinations of methanol hydrogen battery power generation devices to supply power according to a preset hydrogen energy power generation management strategy and in combination with the current electric energy storage status of each methanol hydrogen battery power generation device. The preset hydrogen energy power generation management strategy is used to manage the simultaneous power supply status and power supply parameter ratio of multiple methanol hydrogen battery power generation devices.

[0028] Specifically, the energy management agency obtains the current electric energy storage data of multiple methanol-hydrogen battery power generation devices in real time, and associates the corresponding device identifications; sends different energy storage data to the judgment model, identifies and determines the current energy storage level of each methanol-hydrogen battery power generation device, and determines the methanol-hydrogen battery power generation device with sufficient energy storage; the energy management agency selects the optimal methanol-hydrogen battery power generation device for power supply switching based on the energy storage level evaluation results; when the energy storage level of a methanol-hydrogen battery power generation device is lower than the set threshold, it automatically switches to the methanol-hydrogen battery power generation device with sufficient energy storage to continue supplying power; when the energy storage level of all methanol-hydrogen battery power generation devices is lower than the corresponding set threshold, based on the device identification, the battery energy storage processing prompt instruction is triggered.

[0029] Example scenario: Assume that an industrial zone has installed a methanol hydrogen fuel cell power generation and solar energy integrated power supply system to provide power for multiple important production equipment in the zone. The energy management agency in the system obtains energy storage data once a minute through sensors installed on each methanol hydrogen battery power generation device, and associates it with the corresponding device identification. For example, devices A, B, and C correspond to ID1, ID2, and ID3 respectively; the collected data is sent to the judgment model in the energy management agency, which calculates the current energy storage level of each device based on historical data and algorithms. Assuming that the energy storage level of device A is 80%, device B is 70%, and device C is 90%, the energy management agency selects device C with the highest energy storage level for power supply based on the energy storage level evaluation results. As production activities continue, the energy storage level of device C gradually drops to 45%, which is lower than the set threshold of 45%, and automatically switches to device A with a relatively high energy storage level to continue powering, ensuring that the power supply of production equipment is not affected; Assume that after a period of time, due to long-term high-load operation, the energy storage levels of devices A, B, and C all drop to 40%, which is lower than the set threshold of 45%. At this time, the energy management agency triggers the battery energy storage processing prompt instruction and immediately starts the backup battery energy storage device to ensure that the power supply of key production equipment is not interrupted.

[0030] In one embodiment, when there are many target power-consuming devices and the area where power supply is required is widely distributed, for example, a large commercial complex installs a methanol hydrogen fuel cell power generation and solar energy integrated power supply system to provide power for shopping malls, office areas and data centers, in order to improve the intelligent management level of the methanol hydrogen fuel cell power generation and solar energy integrated power supply system.

[0031] Specifically, the hydrogen power generation management strategy is a dynamic control strategy, and the method for obtaining the hydrogen power generation management strategy includes: S1: The energy management agency monitors the real-time power consumption of the target electrical equipment, records the power demand at each moment and classifies the loads according to the load priority, and obtains the load change information and the corresponding load priority.

[0032] Specifically, high-precision current and voltage sensors are installed to collect power consumption data of electrical equipment in real time, and machine learning or rule engines are used to classify loads. The priority of each load is determined based on historical data and preset rules. For example, office equipment in a data center is a high priority, factory production lines are a medium priority, and lighting equipment in office areas is a low priority. The priority of each load can also be customized according to specific usage requirements.

[0033] S2: Create multiple power supply time periods according to the power consumption time periods in the multiple load change information and the demand patterns of loads with different priorities.

[0034] Specifically, based on the time series analysis of historical load data, different power consumption patterns (such as the morning peak period, midday period, and night period on weekdays) are identified, and corresponding power supply periods are created.

[0035] S3: According to multiple power supply time periods, multiple load change information is classified and processed to obtain multiple power supply task sets, each of which includes a power demand forecast and corresponding power supply arrangement within a specific time period.

[0036] Specifically, a clustering algorithm is used to classify load change information to ensure that similar load demands are classified into the same category, and a prediction model (such as time series prediction, regression analysis, etc.) is used to predict future power demand to ensure the accuracy of power supply arrangements.

[0037] S4: Generate a hydrogen power generation management strategy based on multiple power supply task sets and current energy storage levels of multiple methanol hydrogen battery power generation devices.

[0038] Specifically, the optimization algorithms of linear programming and genetic algorithm are used, combined with the real-time status of the energy storage device and the load demand, to generate the most reasonable power supply strategy.

[0039] In one embodiment, in step S2, multiple power supply periods are created according to the power consumption periods in the multiple load change information and the demand patterns of loads with different priorities, specifically including: S21: Determine a plurality of different first load change information pieces according to power demand cycles in the plurality of load change information pieces.

[0040] In this embodiment, the first load change information is the basis for creating a power supply period. By analyzing the time series of historical load data, the first significant load change in different time periods is identified, and preset rules (such as the mutation point of power demand, changes at specific time points, etc.) are used to determine which load change information can be used as the first one, such as the peak power consumption of the data center at 8 am on weekdays and the start-up of the factory production line at 3 pm.

[0041] S22: Based on several different first load change information and preset fixed power supply durations, combined with the current energy storage levels of multiple methanol hydrogen battery power generation devices, multiple initial power supply time periods are created accordingly, and the maximum power supply time of each initial power supply time period meets the sum of the power demand cycle of the first load change information and the fixed power supply duration.

[0042] In this embodiment, based on the power demand cycle of the first load change information and the preset fixed power supply duration, the start and end time and the maximum power supply time of each initial power supply period are dynamically planned, and the energy storage level of each methanol hydrogen battery power generation device is evaluated in real time to ensure that the created initial power supply period can meet the demand when there is sufficient energy storage. For example, if the power demand cycle of a first load change information is 60 minutes and the fixed power supply duration is 30 minutes, then the maximum power supply time of the initial power supply period is 90 minutes. By finely tracking and monitoring the power demand of each power load, while meeting the power demand of the target power equipment, the adaptability of the integrated power supply system to complex and changeable load power demands is improved.

[0043] S23: Determine the power supply period to be combined and the corresponding power supply task set based on the power demand cycle of the currently processed load change information, and merge the currently processed load change information into the power supply task set corresponding to the power supply period to be combined.

[0044] In this embodiment, a matching algorithm (such as a greedy algorithm or an optimization algorithm) is used to find the power supply period and task set that best suits the current load change information. Once a suitable power supply period and task set are determined, the currently processed load change information is immediately merged into the corresponding task set, and the task set content is updated. For example, based on the currently processed load change information (such as the startup of a new temporary equipment at 9 a.m.), a matching algorithm is used to find the most suitable power supply period and task set (such as the data center power supply period at 8 a.m.).

[0045] In one embodiment, the energy management mechanism of the methanol hydrogen fuel cell power generation and solar energy integrated power supply system further includes: S10: Determine the currently processed load change information and the created power supply time periods according to the power demand cycles in the multiple load change information, wherein the created power supply time periods are all associated with the power supply task set, and the created power supply time periods include expandable power supply time periods.

[0046] Specifically, the expandable power supply period includes: expanding the expandable power supply period into an increased power supply period or a reduced power supply period according to a preset dynamic adjustment duration; the time range of the increased power supply period is obtained by calculating the time increase based on the next load change information to be processed, and the time range of the reduced power supply period is obtained by calculating the time decrease based on the next load change information to be processed; the preset dynamic adjustment duration is obtained by associating and mapping based on the device identification of the methanol hydrogen battery power generation device, and is optimized and adjusted based on the current energy storage level of the methanol hydrogen battery power generation device.

[0047] For example, let the power supply period be [T x , T y ], the dynamic adjustment duration is C, and the expandable power supply period is [T y -C, T x +C]; Determine whether the power demand period t of the currently processed load change information is within the initial extended power supply period. If T x ≤t≤T y , it is confirmed that the next load change information to be processed is within the existing power supply period and no extended processing is required, that is, the power supply period [T x , T y ] and scalable power supply period [T y -C, T x +C] unchanged; If T y <t≤T x +C, it is determined that the power supply period corresponding to the next load change information to be processed is the increased power supply period, and the power supply period is extended by T new Expanded to [T x , t], the scalable call log compression time interval is [tC, T x +C]; If T y -C<t<T x , then the next extension to be processed is determined to be [t, T y ], the power supply period corresponding to the load change information is the reduced power supply period, and the power supply period is extended by T new The scalable call log compression time interval is [T y -C, t+C].

[0048] S20: If new load change information appears within the created power supply period, determine whether the new load change information is consistent with the existing power supply period.

[0049] S30: If the power demand cycle of the currently processed load change information is within the created power supply period, the currently processed load change information is merged into the corresponding power supply task set.

[0050] S40: If the power demand cycle of the currently processed load change information is not within the created power supply period, but within the extendable period of the created power supply period, the power supply time range and the extendable period time range of the power supply period are updated with the power demand cycle of the current load change information, and the currently processed load change information is merged into the updated power supply period.
