Description

TECHNICAL FIELD

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

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

[0003] The existing battery technology cannot maintain high-power electricity for a long time, and the use of fuel engines will increase the operating cost and the risk of environmental pollution. If an emergency occurs during navigation, such as fuel depletion, the ship may face the risk of power failure. The renewable energy power supply system based on solar energy and hydrogen energy still has some deficiencies in practical application: whether the power supply scheme based on a single energy source (such as only relying on solar energy) or a hybrid energy system, when facing changes in natural conditions (such as night or cloudy days), sudden load increases, etc., it may encounter unstable power supply challenges, and it is difficult to meet the demand of complex and variable workloads, especially during peak periods, which may cause overload and power failure. 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

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

[0005] In the first aspect, the application aims to achieve the following technical solutions:

[0006] The methanol hydrogen fuel cell power generation and solar integrated power supply system comprises an energy management mechanism, a solar power generation device, a battery energy storage device, and a plurality of methanol hydrogen battery power generation devices.

[0007] The energy management mechanism obtains the power supply demand parameters of the target electrical equipment, and based on the current energy storage status of the solar power generation device, the plurality of methanol hydrogen battery power generation devices and the battery energy storage device, controls each power supply device to start power supply and shut down to supply power to the target electrical equipment.

[0008] 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 according to a preset hydrogen energy power generation management strategy in combination with the current electric energy storage conditions of each methanol hydrogen battery power generation device when the methanol hydrogen battery power generation device supplies power.

[0009] By adopting the technical scheme, the target power equipment includes a hydrogen fuel cell vehicle hydrogen filling station, electrical loads inside and around a building, a data center, and other high-power consumption facilities. In order to realize stable power supply to the target power equipment and optimize energy utilization efficiency, the application adopts an intelligent power supply control, power supply mode priority management (such as preferential solar power supply, methanol hydrogen battery power generation device power supply, and finally battery energy storage device power supply), and a collaborative comprehensive management mode of hydrogen energy power generation management strategy. Specifically, after analyzing power supply demand parameters of the target power equipment, the current electric energy storage conditions of the solar power generation device, the plurality of methanol hydrogen battery power generation devices, and the battery energy storage device are evaluated. According to the evaluation results, each power supply device is dynamically started or stopped to meet the demand of the target power equipment. For example, when solar power supply meets the power demand of the target power equipment, only solar power supply is used. When solar power cannot 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 demand) is controlled to supply power. By combining solar power generation and hydrogen energy storage, solar energy can be fully utilized during the day, and the excess energy is used to produce hydrogen and stored in the methanol hydrogen battery power generation device. At night or in other insufficient light conditions, hydrogen power is relied on to provide stable power support. This not only improves the self-sufficiency rate of the overall energy system, but also reduces the dependence on external power grids. Further, when the methanol hydrogen battery power generation device supplies power, the energy management mechanism determines how to switch different methanol hydrogen battery power generation devices to supply power according to the preset hydrogen energy power generation management strategy, so as to select the optimal power supply combination to supply power and ensure the continuity and stability of power output. That is, the power supply parameter proportion between each methanol hydrogen battery power generation device is flexibly adjusted according to different time periods or load changes. Since there are multiple methanol hydrogen battery power generation devices, even if a device fails or has a low energy storage level, it can be immediately switched to other normally operating devices for continuous power supply, avoiding the risk of power failure due to failure of a single power supply point, thereby enhancing the reliability and safety of the power supply system.

[0010] In a preferred example, when the methanol hydrogen battery power generation device supplies 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 according to a preset hydrogen energy power generation management strategy in combination with the current electric energy storage conditions of each methanol hydrogen battery power generation device, specifically including:

[0011] The energy management mechanism obtains current energy storage data of a plurality of methanol hydrogen battery power generation devices in real time, and associates corresponding device identifiers;

[0012] Different energy storage data are sent to a 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;

[0013] The energy management mechanism selects the optimal 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 certain methanol hydrogen battery power generation device is lower than a set threshold, it is automatically switched to a methanol hydrogen battery power generation device with sufficient energy storage for continuous power supply;

[0014] When all the methanol hydrogen battery power generation devices are lower than the corresponding set threshold, a battery energy storage processing prompt instruction is triggered based on the device identifier.

[0015] By adopting the above technical solution, the energy storage level changes of a plurality of methanol hydrogen battery power generation devices are monitored in real time to accurately grasp the energy storage state of the plurality of methanol hydrogen battery power generation devices, reduce power supply interruption caused by insufficient energy storage, automatically switch to a methanol hydrogen battery power generation device with sufficient energy storage for continuous power supply when the energy storage level of a certain methanol hydrogen battery power generation device is lower than a set threshold, and ensure the continuity and stability of power supply. The hydrogen energy power generation management strategy of the present application selects the optimal methanol hydrogen battery power generation device for power supply switching according to the energy storage level evaluation result, ensures that each power supply is provided by the current most suitable energy storage device, thereby maximizing energy utilization efficiency. The hydrogen energy power generation management strategy supports dynamic adjustment of power supply arrangement according to real-time load changes and energy storage conditions, further improves the response speed and adaptability of the system, and reduces unnecessary energy waste.

[0016] In a preferred example of the present application, the hydrogen energy power generation management strategy is a dynamic control strategy, and the method for obtaining the hydrogen energy power generation management strategy comprises:

[0017] The energy management mechanism monitors the real-time power consumption of the target power consumption equipment, records the power demand at each moment, and classifies the load according to the load priority to obtain load change information and corresponding load priority;

[0018] According to the power consumption period in the plurality of load change information and the demand mode of different priority loads, a plurality of power supply periods are created;

[0019] According to the plurality of power supply periods, the plurality of load change information are classified and processed to correspondingly obtain a plurality of power supply task sets, each power supply task set containing power demand prediction and corresponding power supply arrangement in a specific time period;

[0020] According to the current energy storage levels of the plurality of methanol hydrogen battery power generation devices and the plurality of power supply task sets, a hydrogen energy power generation management strategy is generated.

[0021] By adopting the above technical solutions, in order to improve the response speed, adaptability and energy utilization efficiency of the methanol hydrogen fuel cell power generation and solar integrated power supply system, the energy management mechanism is used to monitor the real-time power consumption of the target power consumption equipment, and the loads are classified according to the load priority, and a hydrogen energy power generation management strategy is generated. Specifically, according to the power consumption time period in the plurality of load change information and the demand mode of the different priority loads, a plurality of power supply time periods are created, the system is allowed to flexibly adjust the power supply plan according to the actual demand, and a plurality of power supply task sets are obtained by classifying and processing the plurality of load change information. Each power supply task set contains power demand prediction and corresponding power supply arrangement in a specific time period. Through accurate classification, energy resources can be more effectively allocated. Based on the plurality of power supply task sets and the current energy storage levels of the plurality of methanol hydrogen battery power generation devices, a hydrogen energy power generation management strategy is generated. Not only the load demand is considered, but also the state of the energy storage device is combined to realize optimal energy allocation. Through load priority classification, the system can meet the demand of key loads in the case of limited resources, and improve the reliability and safety of the entire system.

[0022] In a preferred example of the present application, when a plurality of power supply time periods are created according to the power consumption time period in the plurality of load change information and the demand mode of the different priority loads, it includes:

[0023] According to the power demand period in the plurality of load change information, a plurality of different first load change information is determined;

[0024] According to the plurality of different first load change information and the preset fixed power supply time length, 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 created. The maximum power supply time of each initial power supply time period satisfies the sum of the power demand period of the first load change information and the fixed power supply time length;

[0025] Based on the power demand period of the currently processed load change information, the power supply time 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 time period to be combined.

[0026] By adopting the technical scheme, the first load change information is recognized and processed, the system can quickly respond to new load demand, ensures that each new load change can be timely included in the power supply plan, creates an initial power supply time period according to the first load change information and the fixed power supply time length, so that each power supply time period can accurately match the actual load demand, and the situation of excessive or insufficient power supply is avoided, and the power supply time period and the task set are dynamically adjusted according to the currently processed load change information, so that the resource allocation always meets the actual demand, and the energy utilization efficiency is further improved, when a power supply time period ends or needs to be adjusted, the system can quickly find a suitable to-be-combined power supply time period, and the new load change information is combined into the to-be-combined power supply time period, and the continuity of power supply is ensured, and the power demand cycle based on the currently processed load change information is used to determine the to-be-combined power supply time period, so that the system can flexibly cope with new load demand while maintaining the existing power supply arrangement, and the adaptability of the system is enhanced.

[0027] 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 time period according to the power demand cycle in the plurality of load change information, the created power supply time period is associated with a power supply task set, and the created power supply time period includes an expandable power supply time period.

[0028] If new load change information appears in the created power supply time period, it is judged whether the new load change information meets the existing power supply time period.

[0029] If the power demand cycle of the currently processed load change information is within the created power supply time period, the currently processed load change information is merged into the corresponding power supply task set.

[0030] If the power demand cycle of the currently processed load change information is not within the created power supply time period, but is within the expandable time period of the created power supply time period, the power supply time range and the expandable time range of the power supply time period are updated according to the power demand cycle of the current load change information, and the currently processed load change information is merged into the updated power supply time period.

[0031] If the power demand cycle of the currently processed load change information is not within the created power supply time period, and cannot be merged with the created power supply time period, a new power supply time 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 time period.

[0032] By adopting the above technical solutions, the dynamic load change response capability is improved, the system maintains high efficiency under various working conditions, the power supply period and task set are continuously updated and adjusted, self-optimization is performed according to historical data and real-time feedback, long-term stable operation is ensured, the energy storage level and load demand are continuously monitored, early warning is given when the energy storage level approaches the critical value, preventive measures are taken, such as starting a backup energy storage device or adjusting non-critical loads, the power supply at the user end is more stable and smooth, the inconvenience caused by unstable power supply is reduced, and the user experience is improved. For new load change information that cannot be merged with the existing power supply period, the system creates a new power supply period and its corresponding power supply task set based on the power demand cycle of the new load change information, ensuring that each load is reasonably allocated resources.

[0033] In a preferred example of the present application, the extendable period of the power supply period includes:

[0034] The extendable power supply period is extended into an extended-time power supply period or a reduced-time power supply period according to a preset dynamic adjustment duration; the time range of the extended-time power supply period is calculated by increasing the time based on the next piece of load change information to be processed, and the time range of the reduced-time power supply period is calculated by reducing the time based on the next piece of load change information to be processed;

[0035] The preset dynamic adjustment duration is obtained by association mapping based on the device identifier 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.

[0036] By adopting the above technical solutions, the time range of the extended-time power supply period and the reduced-time power supply period is calculated based on specific load change information, ensuring that each adjustment is made to better match the actual load demand and avoid 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 overall energy utilization efficiency. When the power supply period needs to be extended, the system can smoothly incorporate new load change information into the existing power supply plan, ensuring the continuity of power supply.

[0037] In a second aspect, the application aims to achieve the following technical solutions:

[0038] The 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:

[0040] When the methanol hydrogen battery power generation device supplies power, the energy management mechanism switches different methanol hydrogen battery power generation devices or different combinations of methanol hydrogen battery power generation devices for power supply according to the preset hydrogen energy power generation management strategy combined with the current energy storage conditions of each methanol hydrogen battery power generation device. The preset hydrogen energy power generation management strategy is used to manage the simultaneous power supply state and power supply parameter ratio of the plurality of methanol hydrogen battery power generation devices.

[0041] By adopting the above technical solution, the energy management mechanism switches different methanol hydrogen battery power generation devices or combinations flexibly according to the preset hydrogen energy power generation management strategy combined with the current energy storage conditions, enhances the adaptability and flexibility of the system, maximizes the use of existing energy storage resources by accurately evaluating the energy storage level and optimizing the power supply parameter ratio, and improves the energy utilization efficiency.

[0042] In a preferred example of the present application, the method further comprises:

[0043] When a plurality of power supply periods are created, the creation time of the plurality of power supply periods is recorded;

[0044] It is judged whether the creation time of the plurality of power supply periods meets the preset timeout time;

[0045] If it is identified that the creation time of a power supply period meets the preset timeout time, the power supply period is finally confirmed and a power supply switching control instruction is triggered.

[0046] By adopting the above technical solution, according to the set preset timeout time, the system can quickly identify the power supply period that is not completed within the predetermined time, and take corresponding measures to avoid power supply interruption or instability caused by delay. When the power supply period reaches the preset timeout time, the system will finally confirm and trigger the power supply switching control instruction, ensuring the reasonable allocation and efficient use of resources, and avoiding the long-time occupation of unnecessary energy storage devices. Once it is identified that the power supply period is overdue, the system immediately triggers the power supply switching control instruction to ensure that the new power supply arrangement can quickly take over and maintain the continuity of power supply.

[0047] In a third aspect, the application achieves the purpose of the invention by adopting the following technical solution:

[0059] The present application will be further described in detail below with reference to the accompanying drawings.

[0060] In an embodiment, as shown in Figure 1 and Figure 2 , the present application discloses a methanol hydrogen fuel cell power generation and solar integrated power supply system, which includes an energy management mechanism, a solar power generation device, a battery energy storage device, and a plurality of methanol hydrogen battery power generation devices. The solar power generation device is a device for generating solar power based on a solar cell panel assembly. The battery energy storage device is a device composed of energy storage batteries. The methanol hydrogen battery power generation device is a device that generates 99.975% or more pure hydrogen after reforming methanol water fuel to produce rich hydrogen and purifying it through palladium or pressure swing adsorption, then generates electricity through a hydrogen fuel cell (a device that directly converts the chemical energy of hydrogen and oxygen into electrical energy), and finally outputs electricity.

[0061] The energy management mechanism obtains the power supply demand parameters of the target power consumption equipment, and controls each power supply device to start power supply and shut down based on the current electric energy storage conditions of the solar power generation device, the plurality of methanol hydrogen battery power generation devices and the battery energy storage device, so as to supply power to the target power consumption equipment; when the methanol hydrogen battery power generation device supplies power, the energy management mechanism switches different methanol hydrogen battery power generation devices or different combinations of methanol hydrogen battery power generation devices for power supply according to a preset hydrogen energy power generation management strategy in combination with the current electric energy storage conditions of each methanol hydrogen battery power generation device. The preset hydrogen energy power generation management strategy is used to manage the simultaneous power supply state and power supply parameter proportion of the plurality of methanol hydrogen battery power generation devices.

[0062] Specifically, the energy management mechanism obtains the current electric energy storage data of the plurality of methanol hydrogen battery power generation devices in real time, and associates the corresponding device identifiers; different storage data are sent to a judgment model to identify and determine the current storage level of each methanol hydrogen battery power generation device, and determine the methanol hydrogen battery power generation devices with sufficient storage; the energy management mechanism selects the optimal methanol hydrogen battery power generation device for power supply switching according to the storage level evaluation result; when the storage level of a certain methanol hydrogen battery power generation device is lower than a set threshold, the energy management mechanism automatically switches to the methanol hydrogen battery power generation device with sufficient storage to continue power supply; when all the methanol hydrogen battery power generation devices are lower than the corresponding set threshold, the energy management mechanism triggers a battery energy storage processing prompt instruction based on the device identifier.

[0063] For example, assume that a methanol hydrogen fuel cell power generation and solar integrated power supply system is installed in an industrial area to provide power for multiple important production equipment in the area. The energy management mechanism in the system obtains storage data from sensors installed on each methanol hydrogen battery power generation device every minute, and associates the data with corresponding device identifiers, for example, devices A, B and C correspond to IDs 1, 2 and 3 respectively. The collected data is sent to a judgment model in the energy management mechanism, which calculates the current storage level of each device according to historical data and algorithms. Assume that the storage level of device A is 80%, device B is 70% and device C is 90%. The energy management mechanism selects device C with the highest storage level for power supply according to the storage level evaluation result. As the production activities continue, the storage level of device C gradually decreases to 45%, which is lower than the set threshold of 45%. The energy management mechanism automatically switches to device A with a relatively high storage level to continue power supply, ensuring that the power supply of the production equipment is not affected.

[0064] Assume that after a period of time, due to long-time high-load operation, the storage levels of devices A, B and C all decrease to 40%, which is lower than the set threshold of 45%. At this time, the energy management mechanism triggers a battery energy storage processing prompt instruction, and immediately starts a backup battery energy storage device to ensure uninterrupted power supply for critical production equipment.

[0065] In an embodiment, when a target power-consuming device is encountered, and the area distribution range of the power supply is wide, for example, a large commercial complex is installed with a methanol hydrogen fuel cell power generation and solar integrated power supply system, which is used to provide power for the shopping mall, office area and data center, in order to improve the intelligent management level of the methanol hydrogen fuel cell power generation and solar integrated power supply system.

[0066] Specifically, the hydrogen energy power generation management strategy is a dynamic control strategy, and the method for obtaining the hydrogen energy power generation management strategy comprises the following steps:

[0067] S1: The energy management mechanism monitors the real-time power consumption of the target power-consuming device, records the power demand at each moment, and classifies the load according to the load priority, to obtain load change information and corresponding load priority.

[0068] Specifically, high-precision current and voltage sensors are installed to collect power consumption data of the power-consuming device in real time, machine learning or rule engine is used to classify the load, and the priority of each load is determined according to historical data and preset rules, such as office equipment in the data center being high priority, production line in the factory being medium priority, and lighting equipment in the office area being low priority. The priority of each load can also be customized according to specific use requirements.

[0069] S2: According to the power consumption period in the plurality of load change information and the demand mode of the different priority loads, a plurality of power supply periods are created.

[0070] Specifically, according to the time series analysis of historical load data, different power consumption modes (such as early peak period, midday period and night period on weekdays) are identified, and corresponding power supply periods are created.

[0071] S3: According to the plurality of power supply periods, the plurality of load change information is classified and processed, and a plurality of power supply task sets are correspondingly obtained, each power supply task set containing power demand prediction and corresponding power supply arrangement in a specific time period.

[0072] Specifically, clustering algorithm is used to classify the load change information, to ensure that similar load demand is classified into the same category, and prediction model (such as time series prediction, regression analysis, etc.) is used to predict future power demand, to ensure the accuracy of power supply arrangement.

[0073] S4: According to the plurality of power supply task sets and the current energy storage level of the plurality of methanol hydrogen fuel cell power generation devices, a hydrogen energy power generation management strategy is generated.

[0074] Specifically, linear programming, genetic algorithm optimization algorithm is used, combined with the real-time state of the energy storage device and the load demand, to generate the most reasonable power supply strategy.

[0075] In an embodiment, in step S2, according to the power consumption period and the demand mode of different priority loads in the plurality of load change information, a plurality of power supply periods are created, specifically including:

[0076] S21: According to the power demand period in the plurality of load change information, a plurality of different first load change information are determined.

[0077] In this embodiment, the first load change information is the basis for creating the power supply period. By analyzing the time series of historical load data, the first significant load change in different time periods is identified, and a preset rule (such as the mutation point of power demand, the change at a certain time point, etc.) is used to determine which load change information can be used as the first one, for example, the data center power consumption peak at 8 am on weekdays, the factory production line start at 3 pm, etc.

[0078] S22: According to the plurality of different first load change information and the preset fixed power supply time length, in combination with the current energy storage level of the plurality of methanol hydrogen battery power generation devices, a plurality of initial power supply periods are created, and the maximum power supply time of each initial power supply period meets the sum of the power demand period of the first load change information and the fixed power supply time length.

[0079] In this embodiment, based on the power demand period of the first load change information and the preset fixed power supply time length, 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 real-time evaluated, to ensure that the created initial power supply period can meet the demand under sufficient energy storage, for example, the power demand period of a certain first load change information is 60 minutes, and the fixed power supply time length 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, the power demand of the target power equipment is met while the adaptability of the integrated power supply system to complex and variable load power demand is improved.

[0080] S23: Based on the power demand period 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.

[0081] In this embodiment, by using a matching algorithm (such as a greedy algorithm or an optimization algorithm), the most suitable power supply period and task set for the current load change information are found, and once the appropriate power supply period and task set are determined, the currently processed load change information is immediately merged into the corresponding task set to update the task set content; for example, according to the currently processed load change information (such as the start of a temporary device at 9 am), the most suitable power supply period and task set (such as the data center power supply period at 8 am) are found using the matching algorithm.

[0082] In one embodiment, the energy management mechanism of the methanol hydrogen fuel cell power generation and solar integrated power supply system further includes:

[0083] S10: Based on the power demand cycle in multiple load change information, determine the currently processed load change information and the created power supply period. The created power supply period is associated with the power supply task set, and the created power supply period includes expandable power supply periods.

[0084] Specifically, the expandable power supply period includes: expanding the expandable power supply period into an extended power supply period or a reduced power supply period according to a preset dynamic adjustment duration; the time range of the extended power supply period is calculated by increasing the time based on the next load change information to be processed, and the time range of the reduced power supply period is calculated by decreasing the time based on the next load change information to be processed; the preset dynamic adjustment duration is obtained by associating and mapping the device identifier 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.

[0085] For example, let the power supply period be [T] x T y The dynamically adjustable duration is C, and the expandable power supply period is [T]. y -C,T x +C];

[0086] Determine whether the power demand period t of the currently processed load change information falls within the initial extended power supply period. If T x ≤t≤T y If the next pending load change information is within the existing power supply period, no further processing is required; that is, the power supply period [T] is considered complete. x T y ] and scalable power supply periods [T y -C,T x +C] remains unchanged;

[0087] If T y <t≤T x +C, then the power supply period corresponding to the next load change information to be processed is determined to be the extended power supply period, and the power supply period is extended by T. new Expanded to [T] x If scalable, the single compression time interval is [tC, T]. x +C];

[0088] If T y -C<t<T x Then the next pending extension 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 extensible billing compression time interval is [T y -C, t+C].
