Description

Technical Field

[0001] The present application relates to the field of energy technology of wind-solar hydrogen production systems, and in particular to an energy control method and related equipment for a distributed wind-solar hydrogen production system. Background Art

[0002] With the transformation of the global energy structure and the rapid development of renewable energy, wind and solar power generation systems have been widely used. At the same time, hydrogen energy, as a clean and efficient energy carrier, has shown great potential in energy storage and conversion. Combining wind and solar power generation with hydrogen production technology to form a wind and solar hydrogen production system has become an important research direction in the energy field.

[0003] At present, distributed wind and solar power hydrogen production systems usually adopt independent energy management methods. This management mode is adopted because in practical applications, the composition of distributed wind and solar power hydrogen production subsystems may be in various situations: it may only include wind and solar power generation subsystems, it may only include water electrolysis hydrogen production subsystems, or it may include both wind and solar power generation and water electrolysis hydrogen production subsystems. Based on this diversity, independent management methods are widely used. In this mode, the wind and solar power generation subsystem and the water electrolysis hydrogen production subsystem perform energy management separately. The wind and solar power generation subsystem is responsible for converting wind energy and solar energy into electrical energy. The water electrolysis hydrogen production subsystem receives electrical energy and manages the process of water electrolysis hydrogen production through its own control system. The two subsystems operate independently and realize energy transfer through simple power transmission.

[0004] However, the lack of overall coordination results in inefficient energy utilization. Summary of the invention

[0005] The present application provides an energy control method and related equipment for a distributed wind-solar hydrogen production system, which are used to improve energy utilization efficiency.

[0006] In a first aspect, the present application provides an energy control method for a distributed wind-solar hydrogen production system, comprising: Determine multiple virtual roles that can be played simultaneously for each wind-solar hydrogen production subsystem, the virtual roles include at least one of a wind-solar power generator, a hydrogen power generator, a power supplier, an electricity user, and a hydrogen supplier, wherein a single wind-solar hydrogen production subsystem can play multiple virtual roles simultaneously; According to the multiple virtual roles that can be played at the same time, the classification of the upper virtual roles that each wind-solar hydrogen production subsystem can play at the same time is determined. The upper virtual roles include producers, contributors and storage. Among them, a single wind-solar hydrogen production subsystem can play multiple upper virtual roles at the same time: Create a virtual ID card for each upper virtual role of each wind-solar hydrogen production subsystem, and the virtual ID card contains the parameters of the corresponding upper virtual role; Obtain external environment data; According to the external environment data and the virtual ID card of each wind-solar hydrogen production subsystem, the task volume of each wind-solar hydrogen production subsystem is determined, where the contributors plus the storage of each wind-solar hydrogen production subsystem equal the task volume of the producer; Assign tasks to each wind-solar hydrogen production subsystem.

[0007] By adopting the above technical solution, the wind-solar hydrogen production system is disassembled into multiple virtual roles with clear functions, and then these roles are merged into upper-level virtual roles, so as to achieve functional integration and simplified management. Each upper-level virtual role is equipped with a unique virtual ID card, which can quickly capture its key parameters and combine it with external environmental data to achieve personalized task allocation, and jointly manage the wind-solar power generation subsystem and the water electrolysis hydrogen production subsystem, forming an integrated management system and enhancing the comprehensive utilization efficiency of energy.

[0008] In combination with some embodiments of the first aspect, in some embodiments: the correspondence between the upper virtual character classification and the virtual character is: When there are both wind and solar power generators and hydrogen power generators, the output is the sum of wind and solar power generators and hydrogen power generators; When there are only wind and solar power generators, the output is the wind and solar power generators; In the case where there are only hydrogen generators, the output is the hydrogen generator; The storer is the user of electricity; When there are both power suppliers and hydrogen suppliers, the contributor is the sum of the power suppliers and hydrogen suppliers; In the case where there is only a power supplier, the contributor is the power supplier; When there is only a hydrogen donor, the contributor is the hydrogen donor.

[0009] By adopting the above technical solution, this correspondence takes into account the situation where wind and solar power generators and hydrogen power generators may exist simultaneously or separately, so that the producer role can adapt to different system configurations. The definition of the contributor role also takes into account different combinations of power suppliers and hydrogen suppliers. This functional integration and management can better adapt to various possible subsystem combinations and improve versatility.

[0010] In combination with some embodiments of the first aspect, in some embodiments: after the step of allocating a task amount to each wind-solar hydrogen production subsystem, the method further includes: Each wind-solar hydrogen production subsystem performs corresponding energy control tasks according to its assigned task volume; among which: When each wind-solar hydrogen production subsystem executes the producer: When the output capacity of wind and solar power generators is sufficient to meet the task volume of the producer, the wind and solar power generators output the corresponding task volume of the producer; When the output capacity of wind and solar power generators is insufficient to meet the task of the producer, the wind and solar power generators output their maximum output capacity, and the remaining part is supplemented by the hydrogen power generator to meet the task of the producer; When executing contributors for each wind-solar hydrogen production subsystem: When the output capacity of the power supplier is sufficient to meet the task volume of the contributor, the power supplier outputs the corresponding task volume of the contributor; When the power supplier's output capacity is insufficient to meet the contributor's task, the power supplier outputs its maximum output capacity, and the remaining part is supplemented by the hydrogen supplier to meet the contributor's task; When executing the storage for each wind-solar hydrogen production subsystem: The storage task volume is equivalent to the electricity consumption of the electricity user.

[0011] By adopting the above technical solutions, for producers, the method gives priority to wind and solar power generation, and only enables hydrogen power generation when it is insufficient, which reflects the principle of renewable energy priority. For contributors, power supply is given priority, and then hydrogen supply is supplemented, which is conducive to improving the efficiency of power utilization. The task volume of the storage is directly related to the amount of electricity used, which simplifies management. This task execution strategy not only ensures the balance of energy supply and demand, but also optimizes the order of utilization of different energy forms. In this way, various energy forms can be managed and utilized more effectively, improving the overall energy utilization efficiency.

[0012] In combination with some embodiments of the first aspect, in some embodiments: after the step of determining the task amount of each wind-solar hydrogen production subsystem according to the external environment data and the virtual ID card of each wind-solar hydrogen production subsystem, the method further includes: Get current time information; Determine the current preset time period according to the current time information; Determine the priority optimization target according to the preset time period, and the priority optimization target includes the preset weights of producers, contributors and storers; Adjust the task load of each wind-solar-hydrogen production subsystem according to the priority optimization target.

[0013] By adopting the above technical solution, by obtaining the current time information and determining the preset time period, the priority optimization target can be adjusted according to the characteristics of different time periods. This mechanism takes into account the weights of producers, contributors and storers, so that the importance of each role can be flexibly adjusted according to time changes. This dynamic adjustment mechanism enables it to better respond to time-related changes in energy demand, thereby achieving more optimized energy management and utilization.

[0014] In combination with some embodiments of the first aspect, in some embodiments: the step of determining the task amount of each wind-solar hydrogen production subsystem according to the external environment data and the virtual ID card of each wind-solar hydrogen production subsystem specifically includes: Initialize the initial task volume of the producers, contributors and storage of each wind-solar hydrogen production subsystem; Determine the current output capacity of each wind-solar hydrogen production subsystem based on weather conditions and the virtual ID card of each wind-solar hydrogen production subsystem; the external environment data includes weather conditions and energy demand; Determine whether the sum of the current output capacities of the wind and solar hydrogen production subsystems meets energy demand; If the energy demand is met, the task volume of each wind-solar hydrogen production subsystem producer is the corresponding current output capacity; The task volume of each wind-solar hydrogen production subsystem contributor is the corresponding current output capacity multiplied by the demand ratio, where the demand ratio is the ratio of the sum of the current output capacity to the energy demand; The task volume of the storage of each wind-solar hydrogen production subsystem is the task volume of the corresponding producer minus the task volume of the contributor; By adopting the above technical solution, the current output capacity is determined according to weather conditions and virtual ID cards, and whether the output capacity of non-renewable resources meets the demand is judged. When the demand is met, the producer's task volume directly corresponds to the current output capacity, and the contributor's task volume is allocated according to the demand ratio. This method not only ensures energy supply, but also avoids wasting renewable resources.

[0015] In combination with some embodiments of the first aspect, in some embodiments: after the step of determining whether the sum of the current output capacities of the wind-solar hydrogen production subsystems meets the energy demand, the method further includes: If the energy demand is not met, the potential output capacity of each wind-solar hydrogen production subsystem is determined based on the virtual ID card of each wind-solar hydrogen production subsystem; The potential output capacity and current output capacity are equal to the total output capacity of the wind-solar hydrogen production subsystem; Calculate the total output capacity of each wind-solar hydrogen production subsystem, where the total output capacity is equal to the sum of the potential output capacity and the current output capacity; Determine whether the total output capacity of the wind and solar hydrogen production subsystems can meet the energy demand; If the sum of total output capacity meets the energy demand, the task of each wind-solar hydrogen production subsystem producer is the corresponding total output capacity multiplied by the actual demand ratio, where the actual demand ratio is the ratio of energy demand to the sum of total output capacity; The task volume of the contributors of each wind-solar hydrogen production subsystem is the task volume of the corresponding producer; The storage task of each wind-solar hydrogen production subsystem is zero.

[0016] By adopting the above technical solution, by calculating the total output capacity (current output capacity plus potential output capacity), when the total output capacity meets the demand, the system allocates tasks according to the actual demand ratio to ensure full utilization of resources. By setting the contributor task volume equal to the producer task volume, it ensures that non-renewable resources will not be over-consumed while ensuring that the demand is met.

[0017] In combination with some embodiments of the first aspect, in some embodiments: after the step of determining whether the sum of the total output capacity of the wind-solar hydrogen production subsystem meets the energy demand, the method further includes: If the sum of the total output capacity does not meet the energy demand, the task volume of each wind-solar hydrogen production subsystem producer is the corresponding total output capacity; The task volume of the contributors of each wind-solar hydrogen production subsystem is the task volume of the corresponding producer; The task volume of the storage of each wind-solar hydrogen production subsystem is zero; Provide early warning information to relevant systems.

[0018] By adopting the above technical solutions and the mechanism for dealing with extreme situations, when the total output capacity is still insufficient to meet the demand, the strategy of maximizing the use of existing resources is adopted, and the task volume of both the producer and the contributor is set to the total output capacity, ensuring that all available resources are fully utilized. At the same time, by providing early warning information to relevant systems, the system can promptly notify managers or other relevant systems so that further response measures can be taken.

[0019] In the second aspect, the present application provides a distributed wind-solar hydrogen production system energy control system, which includes: one or more processors and a memory; the memory is coupled to the one or more processors, the memory is used to store computer program code, the computer program code includes computer instructions, and one or more processors call computer instructions to enable the distributed wind-solar hydrogen production system energy control system to execute the method described in the first aspect and any possible implementation method of the first aspect.

[0020] In the third aspect, the present application provides a computer program product comprising instructions. When the computer program product runs on a distributed wind-solar hydrogen production system energy control system, the distributed wind-solar hydrogen production system energy control system executes the method described in the first aspect and any possible implementation method of the first aspect.

[0021] In a fourth aspect, the present application provides a computer-readable storage medium comprising instructions, which, when executed on a distributed wind-solar-hydrogen production system energy control system, enables the distributed wind-solar-hydrogen production system energy control system to execute the method described in the first aspect and any possible implementation method of the first aspect.

[0022] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: 1. By disassembling the wind-solar hydrogen production system into multiple virtual roles with clear functions, and then merging these roles into upper-level virtual roles, the integration of functions and simplified management are achieved. Each upper-level virtual role is equipped with a unique virtual ID card, which can quickly capture its key parameters and combine it with external environmental data to achieve personalized task allocation. The wind-solar power generation subsystem and the water electrolysis hydrogen production subsystem are jointly managed to form an integrated management system, which enhances the comprehensive utilization efficiency of energy.

[0023] 2. This correspondence takes into account the situation where wind and solar power generators and hydrogen power generators may exist simultaneously or separately, so that the producer role can adapt to different system configurations. The definition of the contributor role also takes into account different combinations of power suppliers and hydrogen suppliers. This functional integration and management can better adapt to various possible subsystem combinations and improve versatility.

[0024] 3. For producers, the method gives priority to wind and solar power generation, and only enables hydrogen power generation when it is insufficient, which reflects the principle of renewable energy priority. For contributors, power supply is given priority, and hydrogen supply is supplemented, which is conducive to improving the efficiency of power utilization. The task volume of the storage is directly related to the amount of electricity used, which simplifies management. This task execution strategy not only ensures the balance of energy supply and demand, but also optimizes the order of utilization of different energy forms. In this way, various energy forms can be managed and utilized more effectively, improving the overall energy utilization efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more listed items.

[0027] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0028] See also Figure 1 :, Figure 1 It is a flow chart of the energy control method of the distributed wind-solar hydrogen production system in the embodiment of the present application; S101, determining a plurality of virtual roles that can be played simultaneously for each wind-solar hydrogen production subsystem, the virtual roles including at least one of a wind-solar power generator, a hydrogen power generator, a power supplier, a power user, and a hydrogen supplier, wherein a single wind-solar hydrogen production subsystem can play a plurality of virtual roles simultaneously; It should be noted that as long as a system has one of the functions of wind and solar power generation or water electrolysis hydrogen production, it can be defined as a wind and solar hydrogen production subsystem. In relevant technologies, usually only systems that have both wind and solar power generation and water electrolysis hydrogen production functions are identified as wind and solar hydrogen production subsystems.

[0029] The virtual roles represent the functional positioning that the system can assume in the energy network. Wind and solar power generators refer to roles that use wind and solar energy to generate electricity; hydrogen power generators refer to roles that use hydrogen to generate electricity; power suppliers refer to roles that provide electricity to the outside; electricity users refer to roles that consume electricity; and hydrogen suppliers refer to roles that provide hydrogen to the outside.

[0030] In some embodiments, according to the hardware configuration and functional characteristics of each wind-solar hydrogen production subsystem, multiple virtual roles that can be played simultaneously are assigned to it. For example, a subsystem equipped with a wind turbine, photovoltaic panels and power transmission equipment will be assigned two virtual roles of wind-solar power generator and power supplier, a subsystem equipped with an electrolyzer, hydrogen storage equipment, and output pipeline will be assigned two virtual roles of power user and hydrogen supplier, and a subsystem equipped with a wind turbine, hydrogen fuel cell, electrolyzer, hydrogen storage equipment, output pipeline and power transmission equipment will be assigned five virtual roles of wind-solar power generator, hydrogen power generator, power supplier, power user and hydrogen supplier.

[0031] In some specific embodiments, the hardware configuration information of each subsystem is obtained; and a corresponding virtual role is automatically assigned to each subsystem according to a preset rule, which is not limited here.

[0032] In other embodiments, it is not enough to have the corresponding hardware configuration and functional characteristics to play the corresponding virtual role. For example, it is also necessary to evaluate the resource availability and whether the relevant resources are sufficient. For example, whether a wind-solar hydrogen production subsystem with hydrogen storage equipment and output pipeline can serve as a hydrogen supplier requires an evaluation of whether it has sufficient hydrogen reserves.

[0033] In some embodiments, the relevant resources must meet the corresponding minimum thresholds so that the wind-solar hydrogen production subsystem can be identified as the corresponding virtual role.

[0034] In some preferred embodiments, only the hydrogen supplier and hydrogen generator roles need to make a double judgment, that is, consider the hardware configuration information and meet the corresponding minimum threshold at the same time. The other roles only need to confirm the hardware configuration information; the reason for this difference is that hydrogen, as an energy carrier in material form, can be accurately measured and calculated, while factors such as the availability of wind energy and light energy and electricity demand are difficult to accurately quantify.

[0035] In some embodiments, at each preset time point, the wind-solar hydrogen production subsystem needs to be updated to determine multiple virtual roles that can be played simultaneously.

[0036] S102. Determine the upper virtual role classification that each wind-solar hydrogen production subsystem can play simultaneously according to the multiple virtual roles that can be played simultaneously. The upper virtual roles include producers, contributors and storers. A single wind-solar hydrogen production subsystem can play multiple upper virtual role classifications simultaneously: The upper-level virtual role refers to the classification of virtual roles after a higher level of abstraction. The producer refers to the role that can produce energy, including wind and solar power generators and hydrogen power generators; the contributor refers to the role that provides energy to the outside of the system, including power suppliers and hydrogen suppliers; the storer is used to represent the role that consumes or stores energy, mainly referring to electricity users.

[0037] It should be noted that the purpose is to simplify system management and decision-making. According to the preset mapping rules, the virtual role of each wind-solar hydrogen production subsystem is converted into the corresponding upper-level virtual role. For example, if a subsystem has both the virtual roles of wind-solar power generator and power supplier, it will be classified into two upper-level virtual roles: producer and contributor.

[0038] In some specific embodiments, the correspondence between the upper virtual character classification and the virtual character is as follows: S1021. When there are both wind and solar power generators and hydrogen power generators, the output is the sum of wind and solar power generators and hydrogen power generators; When it is detected that a subsystem has the ability to generate electricity from both wind and solar power and hydrogen, the two capabilities will be merged and the subsystem will be given the superordinate virtual role of "producer".

[0039] S1022. When there are only wind and solar power generators, the generator is the wind and solar power generator; In some embodiments, when it is identified that a subsystem only has the ability to generate wind and solar power but not other forms of power generation (such as hydrogen power generation), the wind and solar power generator role will be directly mapped to the producer role.

[0040] S1023. When there is only a hydrogen power generator, the generator is the hydrogen power generator; In some embodiments, when it is identified that a subsystem only has the ability to generate electricity from hydrogen but not other forms of power generation (such as wind and solar power generation), the hydrogen generator role is directly mapped to the producer role.

[0041] S1024, the storage user is the electricity user; In some embodiments, a subsystem with power consumption function is directly mapped to the storage role.

[0042] S1025. When there are both power suppliers and hydrogen suppliers, the contributor is the sum of the power suppliers and hydrogen suppliers; In some embodiments, when it is detected that a subsystem has the ability to supply both electricity and hydrogen, these two capabilities are merged and the subsystem is given the superordinate virtual role of "contributor".

[0043] S1026. When there is only a power supplier, the contributor is the power supplier; In some embodiments, when it is identified that a subsystem only has the ability to supply electricity but not other forms of energy (such as hydrogen), the power supplier role is directly mapped to the contributor role.

[0044] S1027. When there is only a hydrogen supplier, the contributor is the hydrogen supplier.

[0045] In some embodiments, when it is identified that a subsystem only has the ability to supply hydrogen but not other forms of energy supply capabilities (such as electricity), the hydrogen supplier role is directly mapped to the contributor role.

[0046] It can be seen that this correspondence takes into account the situation where wind and solar power generators and hydrogen power generators may exist simultaneously or separately, so that the producer role can adapt to different system configurations. The definition of the contributor role also takes into account different combinations of power suppliers and hydrogen suppliers. This functional integration and management can better adapt to various possible subsystem combinations and improve versatility.

[0047] S103, creating a virtual ID card for each upper virtual role of each wind-solar hydrogen production subsystem, where the virtual ID card contains parameters corresponding to the upper virtual role; The virtual ID card refers to a data structure used to describe and identify the characteristics of the upper virtual role of the wind and solar hydrogen production subsystem. The parameters represent the attributes and capability indicators related to a specific upper virtual role, such as production capacity, efficiency, capacity, etc.

[0048] In some embodiments, a virtual ID card is created for each upper virtual role of each wind-solar hydrogen production subsystem. This ID card contains the key parameters of the role, such as the power generation under different wind speeds, the maximum power generation capacity and rated power generation capacity under sufficient hydrogen conditions, etc. Creating these virtual ID cards can quickly obtain and update the capability information of each subsystem under different roles, thereby providing accurate data support for subsequent task allocation and resource scheduling.

[0049] S104, obtaining external environment data; Among them, external environmental data refers to the data set of various external factors that affect the operation of wind and solar hydrogen production systems. These data may include information such as meteorological conditions, grid load, and energy demand.

[0050] In some embodiments, relevant external environmental data are collected in real time or periodically through various data interfaces and information sources. These data are used to optimize system operation, predict energy output and demand, and adjust operation strategies.

[0051] S105, determining the task amount of each wind-solar hydrogen production subsystem according to the external environment data and the virtual ID card of each wind-solar hydrogen production subsystem, wherein the contributors plus the storages of each wind-solar hydrogen production subsystem equal the task amount of the producer; Among them, the task volume refers to the specific workload assigned to each wind and solar hydrogen production subsystem to be completed under different roles.

[0052] See also Figure 2 , Figure 2 This is a flow chart of step S105 in the embodiment of the present application; In some specific embodiments, step S105 specifically includes: S1051, initializing the initial task volume of the producer, contributor and storage of each wind-solar hydrogen production subsystem; In some embodiments, an initial task volume is set for each of the three roles (producer, contributor, and storage) of each wind-solar hydrogen production subsystem. These initial values ​​may be based on historical data, system default settings, or the results of the previous round of operation. The purpose of initialization is to provide a reference point for subsequent task volume adjustments and ensure that the system has a clear starting state.

[0053] S1052, determining the current output capacity of each wind-solar hydrogen production subsystem according to weather conditions and the virtual ID card of each wind-solar hydrogen production subsystem; the external environment data includes weather conditions and energy demand; Among them, weather conditions refer to the current meteorological conditions, such as wind speed, sunshine intensity, etc.; the virtual ID card refers to a digital description of the characteristics and capability information of the wind and solar hydrogen production subsystem; the current output capacity refers to the maximum energy output that the system can generate under given conditions; external environmental data refers to the set of external factors that affect the operation of the system; and energy demand refers to the amount of energy supply that the current system needs to meet.

[0054] In some embodiments, the maximum output capacity that each wind-solar hydrogen production subsystem can achieve under the current circumstances is calculated by combining real-time weather data and the characteristic information of each subsystem (stored in the virtual ID card). This step takes into account the impact of the external environment on system performance and provides a more accurate basis for subsequent task allocation.

[0055] S1053, determining whether the sum of the current output capacities of the wind-solar hydrogen production subsystems meets the energy demand; S1054. If the energy demand is met, the task volume of the producer of each wind-solar hydrogen production subsystem is the corresponding current output capacity; In some embodiments, when the system confirms that the total output capacity is sufficient to meet demand, the current output capacity of each wind-solar hydrogen production subsystem is directly set as the task volume of its producer role. This approach allows each subsystem to operate at its maximum capacity and make full use of the current favorable conditions to maximize output.

[0056] S1055. The task volume of the contributor of each wind-solar hydrogen production subsystem is the corresponding current output capacity multiplied by the demand ratio, where the demand ratio is the ratio of the sum of the current output capacity to the energy demand; In some embodiments, the system first calculates the demand ratio, which is the sum of the current output capacity of all subsystems divided by the actual energy demand. Then, the current output capacity of each subsystem is multiplied by this demand ratio to obtain the task amount of the contributor role of the subsystem. This calculation method ensures that the total contribution amount just meets the actual demand while maintaining the capacity ratio between the subsystems.

[0057] S1056. The task volume of the storage of each wind-solar hydrogen production subsystem is the task volume of the corresponding producer minus the task volume of the contributor; In some embodiments, the system will calculate each wind-solar hydrogen production subsystem, subtract the task volume of its producer role from the task volume of its contributor role, and the difference is the task volume of the storage role of the subsystem. This calculation method ensures the balance of energy and allocates excess output to the energy storage system for subsequent use.

[0058] It can be seen that the current output capacity is determined according to weather conditions and the virtual ID card, and whether the output capacity of non-renewable resources meets the demand is judged. When the demand is met, the producer's task volume directly corresponds to the current output capacity, and the contributor's task volume is allocated according to the demand ratio. This method not only ensures energy supply, but also avoids wasting renewable resources.

[0059] S1057. Determine the potential output capacity of each wind-solar hydrogen production subsystem according to the virtual ID card of each wind-solar hydrogen production subsystem; the potential output capacity and the current output capacity are equal to the total output capacity of the wind-solar hydrogen production subsystem; In some embodiments, the system will calculate the maximum output capacity that each subsystem can achieve under optimal operating conditions based on the performance parameters and technical indicators stored in the virtual ID card of each wind-solar hydrogen production subsystem. This step is intended to explore the potential resources of the system and provide a basis for subsequent task adjustments and resource optimization.

[0060] Add the potential output capacity and current output capacity of each wind-solar hydrogen production subsystem to obtain the total output capacity of the subsystem.

[0061] This step establishes a comprehensive index that includes actual and potential capabilities, providing a more comprehensive reference for subsequent task allocation and system optimization.

[0062] S1058. Calculate the total output capacity of each wind-solar hydrogen production subsystem, where the total output capacity is equal to the sum of the potential output capacity and the current output capacity; In some embodiments, each wind-solar hydrogen production subsystem is calculated, and its potential output capacity and current output capacity are added to obtain the total output capacity of the subsystem. This step provides an important data basis for subsequent system performance evaluation and task allocation.

[0063] S1059, determine whether the total output capacity of the wind and solar hydrogen production subsystems meets the energy demand; In some embodiments, the total output capacity of all wind and solar hydrogen production subsystems is accumulated, and then this sum is compared with the current energy demand. The purpose of this step is to determine whether the system has sufficient production capacity to meet the demand when it is fully utilized, providing key basis for subsequent task allocation strategies.

[0064] S10510. If the sum of the total output capacity meets the energy demand, the task volume of the producer of each wind-solar hydrogen production subsystem is the corresponding total output capacity multiplied by the actual demand ratio, where the actual demand ratio is the ratio of the energy demand to the sum of the total output capacity; In some embodiments, the system first calculates the actual demand ratio, which is the energy demand divided by the sum of the total output capacity. Then, the total output capacity of each wind-solar hydrogen production subsystem is multiplied by this actual demand ratio to obtain the task volume of the producer role of the subsystem. This calculation method ensures that the total output just meets the actual demand, while allocating tasks according to the capacity ratio of each subsystem.

[0065] S10511. The task volume of the contributor of each wind-solar hydrogen production subsystem is the task volume of the corresponding producer; In some embodiments, the producer task of each wind-solar hydrogen production subsystem is directly assigned to the corresponding contributor task. This practice indicates that in this case, the system expects the power supply of each subsystem to match its hydrogen production to achieve balanced energy utilization.

[0066] S10512. The task volume of the storage of each wind-solar hydrogen production subsystem is zero.

[0067] In some embodiments, the system sets the storage task of each wind-solar hydrogen production subsystem to zero. This setting indicates that in the current situation, all the output of the system is used to meet immediate demand and no additional energy storage is required.

[0068] It can be seen that by calculating the total output capacity (current output capacity plus potential output capacity), when the total output capacity meets the demand, the system allocates tasks according to the actual demand ratio to ensure full utilization of resources. By setting the contributor task volume equal to the producer task volume, it ensures that non-renewable resources will not be over-consumed while ensuring that the demand is met.

[0069] S10513. If the sum of the total output capacity does not meet the energy demand, the task volume of the producer of each wind-solar hydrogen production subsystem shall be the corresponding total output capacity; In some embodiments, the total output capacity of each wind-solar hydrogen production subsystem is directly used as the task of the producer of the system. This approach is intended to enable each subsystem to operate at its maximum capacity, which can minimize the energy gap, although it still cannot meet all demand.

[0070] S10514. The task volume of the contributor of each wind-solar hydrogen production subsystem is the task volume of the corresponding producer; In some embodiments, the producer task of each wind-solar hydrogen production subsystem is directly assigned to the corresponding contributor task. This approach ensures that the system's power supply and hydrogen output are balanced, avoiding energy waste or shortage.

[0071] S10515. The task volume of the storage of each wind-solar hydrogen production subsystem is zero; In some embodiments, the system sets the storage task of each wind-solar hydrogen production subsystem to zero. This setting reflects that in the case of insufficient current energy supply, all available energy should be used directly to meet current demand without additional storage.

[0072] S10516. Provide early warning information to relevant systems.

[0073] In some embodiments, the system generates an early warning message containing key information such as current energy demand, actual total output capacity, and the size of the gap, and sends the message to pre-defined relevant systems or responsible persons through a preset communication channel. The purpose of this step is to enable relevant parties to understand the situation in a timely manner and take necessary countermeasures, such as adjusting energy use plans, finding additional energy supply sources, etc.

[0074] It can be seen that the mechanism for dealing with extreme situations, when the total output capacity is still insufficient to meet the demand, adopts the strategy of maximizing the use of existing resources, setting the task volume of both producers and contributors to the total output capacity, ensuring that all available resources are fully utilized. At the same time, by providing early warning information to relevant systems, the system can promptly notify managers or other relevant systems so that further response measures can be taken.

[0075] S106. Allocate a task volume to each wind-solar hydrogen production subsystem.

[0076] It can be seen that by disassembling the wind-solar hydrogen production system into multiple virtual roles with clear functions, and then merging these roles into upper-level virtual roles, the integration of functions and the simplification of management are achieved. Each upper-level virtual role is equipped with a unique virtual ID card, which can quickly capture its key parameters and combine it with external environmental data to achieve personalized task allocation, jointly manage the wind-solar power generation subsystem and the water electrolysis hydrogen production subsystem, forming an integrated management system and enhancing the comprehensive utilization efficiency of energy.

[0077] See also Figure 3 , Figure 3 This is another flow chart of the energy control method of the distributed wind-solar hydrogen production system in the embodiment of the present application; In some embodiments, after step S106, the method further includes: S107, each wind-solar hydrogen production subsystem performs a corresponding energy control task according to its assigned task amount; In some embodiments, each wind-solar hydrogen production subsystem adjusts the operating status and parameters of its internal components according to the previously assigned task volume to complete the specified energy production, storage or supply task.

[0078] S1071, when each wind-solar hydrogen production subsystem executes a producer: when the output capacity of the wind-solar power generator is sufficient to meet the task volume of the producer, the wind-solar power generator outputs the task volume of the corresponding producer; In some embodiments, the possible maximum output capacity is calculated based on the current wind and solar energy resources. If this capacity is equal to or exceeds the assigned task amount, the wind and solar power generator outputs the corresponding producer's task amount.

[0079] S1072. When each wind-solar hydrogen production subsystem executes a producer: when the output capacity of the wind-solar power generator is insufficient to meet the producer's task, the wind-solar power generator outputs its maximum output capacity, and the remaining part is supplemented by the hydrogen power generator to reach the producer's task.

[0080] In some embodiments, the wind and solar power generation equipment will first be operated at maximum capacity to produce as much electricity as possible. Then, the difference between the actual output and the task amount will be calculated, and the hydrogen fuel cell system will be started to accurately produce the amount of electricity corresponding to this difference. This strategy ensures that the system can still stably complete the assigned output task when renewable energy is insufficient, while maximizing the use of clean energy.

[0081] S1073. When each wind-solar hydrogen production subsystem executes a contributor: when the output capacity of the power supplier is sufficient to meet the task volume of the contributor, the power supplier outputs the task volume of the corresponding contributor; In some embodiments, the maximum output capacity of the power supplier is calculated based on the current power supply system status and available resources. If this capacity is equal to or exceeds the task amount assigned to the contributor, the power supplier outputs the corresponding contributor task amount. This ensures that the system can effectively utilize available resources while meeting demand.

[0082] S1074. When each wind-solar hydrogen production subsystem executes a contributor: when the output capacity of the power supplier is insufficient to meet the task of the contributor, the power supplier outputs its maximum output capacity, and the remaining part is supplemented by the hydrogen supplier to meet the task of the contributor; In some embodiments, the power supply equipment is operated at maximum capacity to output as much power as possible. The system then calculates the difference between the actual power output and the mission amount, and activates the hydrogen supply system to accurately provide the energy (in the form of hydrogen) corresponding to this difference. This strategy ensures that the system can fully utilize the high efficiency of power transmission, while flexibly adjusting through hydrogen supply to accurately meet the requirements of the contribution mission.

[0083] S1075. When each wind-solar hydrogen production subsystem executes a storage device, the task volume of the storage device is equal to the power consumption of the power user.

[0084] In some embodiments, the actual power consumption of the electricity user is used as the task of the storer. This correspondence ensures that the system can accurately balance the production and consumption of energy, which may be manifested as the production of a corresponding amount of hydrogen or the storage of an equivalent amount of energy in other forms of energy storage devices.

[0085] It can be seen that for producers, the method gives priority to wind and solar power generation, and only enables hydrogen power generation when it is insufficient, which reflects the principle of renewable energy priority. For contributors, power supply is given priority, and then hydrogen supply is supplemented, which is conducive to improving the efficiency of power utilization. The task volume of the storage is directly related to the amount of electricity used, which simplifies management. This task execution strategy not only ensures the balance of energy supply and demand, but also optimizes the order of utilization of different energy forms. In this way, various energy forms can be managed and utilized more effectively, improving the overall energy utilization efficiency.

[0086] In actual use, since the purposes of different stages are different, for example, more energy needs to be stored during the low electricity consumption period at night, while more energy needs to be released during the peak electricity consumption period during the day, the method in the above embodiment may not be applicable.

[0087] See also Figure 4 , Figure 4 This is another flow chart of the energy control method of the distributed wind-solar hydrogen production system in the embodiment of the present application; In some embodiments, after step S103, the method further includes: S201, obtaining current time information; S202, determining the current preset time period according to the current time information; ,The preset time period refers to a period of time predefined by the system, which is used to divide a day or longer into different time periods; In some embodiments, the acquired current time information is compared with the preset time period boundary to determine which preset time period the current time belongs to.

[0088] S203, determining a priority optimization target according to a preset time period, wherein the priority optimization target includes preset weights of producers, contributors, and storers; In some embodiments, a priority optimization target suitable for the current preset time period is selected or calculated from a preset optimization target library. This target is reflected by giving different weights to producers, contributors, and storers to guide the system on how to balance and optimize the operation of various subsystems in different time periods.

[0089] S204. Adjust the task amount of each wind-solar-hydrogen production subsystem according to the priority optimization target.

[0090] In some embodiments, the task amount of each wind-solar hydrogen production subsystem previously determined is adjusted accordingly according to the weights of various subsystems set in the priority optimization target. Such adjustment may involve increasing or decreasing the hydrogen production, power supply or energy storage of certain subsystems to achieve the optimal operating state in the current period.

[0091] It can be seen that by obtaining the current time information and determining the preset time period, the priority optimization target can be adjusted according to the characteristics of different time periods. This mechanism takes into account the weights of producers, contributors and storers, so that the importance of each role can be flexibly adjusted according to time changes. This dynamic adjustment mechanism enables it to better respond to time-related changes in energy demand, thereby achieving more optimized energy management and utilization.
