Therefore, it is urgent to explore new methods to solve the problem of renewable energy consumption. The production of green hydrogen through renewable energy electrolysis of water and its combination with nitrogen to form green ammonia has become an important direction of exploration both domestically and internationally. At the same time, this is also an important way for the synthetic ammonia industry to achieve carbon emission reduction.

With the goal of maximizing the renewable energy consumption ratio of the renewable energy-based hydrogen production and ammonia synthesis coupled with hydrogen power generation system, an objective function is established based on the multiple operating models and initial installed capacity values. Based on the multiple initial installed capacity values, the objective function is solved using a particle swarm optimization algorithm to obtain the capacity configuration optimization results of the renewable energy-based hydrogen production and ammonia synthesis coupled with hydrogen power generation system.

[0007] The capacity configuration optimization method provided by this invention, by acquiring multiple operating models, can deeply understand the operating rules and interrelationships of various components in the system. Furthermore, by setting the highest renewable energy consumption ratio as the objective and establishing an objective function based on multiple operating models and multiple initial installed capacity values, the complex operating conditions and optimization requirements of the system can be transformed into mathematical expressions, facilitating subsequent solution and optimization using algorithms. Furthermore, it achieves effective integration of system information, enabling the objective function to comprehensively reflect the system's operating characteristics and constraints. This allows for the determination of the system's renewable energy consumption under different installed capacity scales. Thus, the particle swarm optimization algorithm can quickly search the vast space of installed capacity combinations to find the combination of installed capacity that maximizes the renewable energy consumption ratio and determine the final capacity configuration optimization result.

[0038] This embodiment provides a capacity configuration optimization method for controlling a system that is connected to a renewable energy-based hydrogen production and ammonia synthesis coupled hydrogen power generation system.

[0042] Figure 1 This is a flowchart of a capacity configuration optimization method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0043] Step S101: Obtain multiple operating models and multiple initial installed capacity values ​​for a renewable energy hydrogen production and ammonia synthesis coupled with hydrogen power generation system.

[0044] Among them, multiple operating models represent the operating models of each unit in the renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system. They are mathematical descriptions or logical frameworks of the interrelationships and changing patterns of key parameters (such as power, rate, capacity, etc.) between each unit under different operating conditions. They are used to reflect the energy conversion, material flow and synergistic effects of each unit with other units, and help to understand, predict and optimize the system's operating status, so as to improve energy utilization efficiency and economy while ensuring the system's safety and reliability.

[0045] Multiple installed capacity values ​​represent the installed capacity of each unit in a renewable energy hydrogen production and ammonia synthesis coupled with hydrogen power generation system. They are a comprehensive description of the capacity-related parameters of each unit's equipment, reflecting the installed capacity of each unit's equipment. Furthermore, the installed capacity can directly determine the production capacity, energy supply or storage capacity of each unit, thereby affecting the energy conversion efficiency, material output capacity, energy balance and operational economy of the entire system.

[0046] Specifically, multiple operating models may include:

[0047] (1) Operation model of water electrolysis hydrogen production unit: used to describe the relationship between parameters such as hydrogen production power and hydrogen production rate and factors such as renewable energy power generation, equipment installed capacity and operating time during the water electrolysis hydrogen production process.

[0048] (2) Ammonia synthesis unit operation model: used to represent the relationship between parameters such as ammonia synthesis power and hydrogen consumption rate during ammonia synthesis and other factors of the system (such as renewable energy power generation, hydrogen storage, hydrogen power generation, etc.).

[0049] (3) Hydrogen fuel cell power generation unit operation model: It is used to represent the relationship between parameters such as hydrogen power generation power and hydrogen consumption rate during hydrogen fuel cell power generation and factors such as the operating power of water electrolysis hydrogen production unit, the operating power of ammonia synthesis unit, and renewable energy power generation. It can reflect the utilization of hydrogen in the power generation process and the energy balance relationship with other units.

[0050] (4) Hydrogen storage unit operation model: used to describe the relationship between parameters such as hydrogen storage capacity, hydrogen charging rate, and hydrogen release rate in the hydrogen storage unit and the operating status of other parts of the system.

[0051] (5) Electrochemical energy storage unit operation model: used to represent the relationship between parameters such as energy storage discharge power, energy storage charging power, and energy storage charge capacity of the electrochemical energy storage unit and the overall operation of the system. Furthermore, by simulating the charging and discharging process of the electrochemical energy storage unit under different energy input and output conditions, it can reflect its role in balancing the energy supply and demand of the system.

[0052] Furthermore, multiple installed capacity values ​​can include:

[0053] (1) Renewable energy power generation capacity: This represents the total installed capacity of renewable energy power generation units (such as wind turbines and solar photovoltaic panels), which can reflect the system's ability to obtain electricity from renewable energy.

[0054] (2) Installed capacity of water electrolysis for hydrogen production: This represents the total power or production capacity of the water electrolysis hydrogen production unit. It determines the system's ability to produce hydrogen, and thus directly affects the supply of hydrogen required for ammonia synthesis.

[0055] (3) Ammonia synthesis capacity: This represents the total production capacity of the ammonia synthesis unit, which determines the maximum amount of ammonia that the system can produce and is directly related to the ammonia synthesis capacity.

[0056] (4) Installed capacity of hydrogen fuel cell power generation: This represents the total power of the hydrogen fuel cell power generation unit, which reflects the system's ability to generate electricity using hydrogen, and thus affects the redistribution and utilization efficiency of energy within the system.

[0057] (5) Hydrogen storage unit installed capacity: This represents the total storage capacity of the hydrogen storage unit, which determines the system's ability to store hydrogen. It plays a role in regulating the balance of hydrogen supply and demand when renewable energy power generation is unstable or when the demand for synthetic ammonia production changes.

[0058] (6) Installed capacity of electrochemical energy storage unit: This represents the total energy storage capacity of the electrochemical energy storage unit.

[0059] Step S102: With the goal of maximizing the renewable energy consumption ratio of the renewable energy-to-hydrogen-to-ammonia-synthetic-hydrogen-power-generation system, an objective function is established based on multiple operating models and multiple initial installed capacity values.

[0060] The objective function is used to characterize the proportion of renewable energy consumption in the renewable energy-to-hydrogen-to-ammonia-synthetic-hydrogen-power-generation system.

[0061] Specifically, by setting the highest renewable energy consumption ratio as the objective and establishing an objective function that combines multiple operating models and initial installed capacity values, the complex operating conditions and optimization requirements of the system can be transformed into mathematical expressions, facilitating subsequent solution and optimization using algorithms. Furthermore, it achieves effective integration of system information, enabling the objective function to comprehensively reflect the system's operating characteristics and constraints, thereby determining the system's renewable energy consumption under different installed capacity scales.

[0062] Step S103: Based on multiple initial installed capacity values, the objective function is solved using the particle swarm optimization algorithm to obtain the capacity configuration optimization results of the renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system.

[0063] Particle Swarm Optimization (PSO) is a stochastic search optimization algorithm based on swarm intelligence. It simulates the foraging behavior of groups of organisms such as flocks of birds and schools of fish, and treats the solutions to the problem as particles in the search space. Each particle represents a potential solution.

[0064] Specifically, the efficient search and optimization capabilities of the particle swarm optimization algorithm can be utilized to quickly search for the combination of installed capacity that maximizes the proportion of renewable energy consumption within a vast space of installed capacity combinations and determine the final capacity configuration optimization result.

[0065] The capacity configuration optimization method provided in this embodiment can deeply understand the operating rules and interrelationships of various components in the system by acquiring multiple operating models. Furthermore, by setting the highest renewable energy consumption ratio as the objective and establishing an objective function based on multiple operating models and multiple initial installed capacity values, the complex operating conditions and optimization requirements of the system can be transformed into mathematical expressions, facilitating subsequent solution and optimization using algorithms. Furthermore, it achieves effective integration of system information, enabling the objective function to comprehensively reflect the system's operating characteristics and constraints. This allows for the determination of the system's renewable energy consumption under different installed capacity scales. Thus, the particle swarm optimization algorithm can quickly search the vast space of installed capacity combinations to find the combination of installed capacity that maximizes the renewable energy consumption ratio and determine the final capacity configuration optimization result. Therefore, by implementing this invention, various aspects of the system can be comprehensively considered to optimize the system's capacity configuration as a whole, adapting to the characteristics of renewable energy, improving the renewable energy consumption ratio, and alleviating the problem of wind and solar curtailment caused by the randomness, fluctuation, and intermittency of renewable energy output. This provides technical support for achieving efficient utilization and sustainable development of renewable energy.

[0066] This embodiment provides a capacity configuration optimization method for controlling a system that is connected to a renewable energy-based hydrogen production and ammonia synthesis coupled hydrogen power generation system.

[0067] Figure 2 This is a flowchart of a capacity configuration optimization method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0068] Step S201: Obtain multiple operating models and multiple initial installed capacity values ​​for a renewable energy-to-hydrogen-to-ammonia-synthetic-hydrogen-power-generation system. For details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0069] Step S202: With the goal of maximizing the renewable energy consumption ratio of the renewable energy-to-hydrogen-to-ammonia-coupled-hydrogen-power-generation system, an objective function is established based on multiple operating models and multiple initial installed capacity values.

[0070] Specifically, step S202 includes:

[0071] Step S2021: Based on multiple operating models and multiple initial installed capacity values, establish the operating power relationship of each unit in the renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system.

[0072] Specifically, by establishing the operating power relationship formulas of each unit in the renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system, the power relationship and mutual influence between the units of the system can be reflected more accurately.

[0073] In some optional implementations, step S2021 above includes:

[0074] Step a1: Determine multiple installed power values ​​based on multiple initial installed capacity values.

[0075] Step a2: Based on multiple initial installed capacity values ​​and multiple installed power values, establish the renewable energy power generation relationship of the renewable energy power generation unit.

[0076] Step a3: Based on multiple installed capacity values, multiple operating models, and renewable energy power generation power relationship formulas, establish the operating power relationship formulas for each unit.

[0077] Specifically, installed capacity is an indicator that measures the capacity or production / storage capability of each unit, while installed power is related to the actual energy conversion, production, or storage rate of the equipment.

[0078] Furthermore, for renewable energy power generation units, the installed capacity determines the power generation equipment capacity, while the installed power is its actual power generation capacity, which is affected by environmental factors; for water electrolysis hydrogen production units, the installed capacity is used to represent hydrogen production capacity, and the installed power has a proportional relationship with it based on equipment parameters, and is affected by electrolysis efficiency and operating conditions; in ammonia synthesis units, the installed capacity represents production capacity, while the installed power provides energy for the reaction, and is affected by process conditions and catalyst performance; for hydrogen fuel cell power generation units, the installed capacity is the power generation capacity, and the installed power is the rated power, with the actual output affected by fuel cell type and hydrogen supply conditions; for hydrogen storage units, the installed capacity is the hydrogen storage capacity, and the installed power is related to hydrogen compression / liquefaction equipment, and is affected by hydrogen storage methods and conditions; for electrochemical energy storage units, the installed capacity represents energy storage capacity, and the installed power involves charging and discharging, and is affected by battery characteristics.

[0079] Furthermore, based on the relationship between the installed capacity and installed power of each unit, the corresponding installed power value can be determined according to the installed capacity value of each unit.

[0080] Furthermore, the relationship between renewable energy power generation is shown in the following equation (1):

[0081] P RE,t =P HY,t +P W,t +P PV,t +P ST,t (1)

[0082] In the formula: P RE,t P represents the renewable energy power generation at time t; HY,t Let P represent the hydroelectric power generation at time t, as shown in equation (2); W,t Let P represent the wind power generation at time t, as shown in equation (3);PV,t Let P represent the photovoltaic power generation at time t, as shown in equation (4); ST,t Let t represent the solar thermal power generation at time t, as shown in equation (5).

[0083] P HY,t =I HY ·p HY,t (2)

[0084] P W,t =I W ·p W,t (3)

[0085] P PV,t =I PV ·p PV,t (4)

[0086] P ST,t =I ST ·p ST,t (5)

[0087] In the formula: I HY p represents the installed capacity of hydropower generation. HY,t Represents the hydroelectric power output curve at time t; I W Indicates the installed capacity of wind power generation; p W,t Represents the wind power output curve at time t; I PV Indicates the installed capacity of photovoltaic power generation; p PV,t Represents the photovoltaic power output curve at time t; I ST Indicates the installed capacity of concentrated solar power (CSP); p ST,t This represents the solar thermal power output curve at time t.

[0088] Finally, by combining the obtained multiple installed capacity values, multiple operating models, and renewable energy power generation relationship formulas, the operating power relationship formulas for each unit can be established, thereby establishing the operating power correlation between all units in the entire system. Furthermore, through this correlation, the transmission and distribution process of renewable energy power generation in the system, as well as its impact on the operating power of other units, can be more clearly understood. This allows for better coordination of the relationship between renewable energy power generation and other units when optimizing capacity configuration, improving the system's adaptability and absorption capacity for renewable energy, and reducing system instability and energy waste caused by renewable energy fluctuations.

[0089] In some alternative implementations, step a3 above includes:

[0090] Step a31: Based on the renewable energy power generation power relationship, the installed power value and operation model of the water electrolysis hydrogen production unit, establish the first operating power relationship of the water electrolysis hydrogen production unit.

[0091] Specifically, the first operating power relationship is used to characterize the operating power of the water electrolysis hydrogen production unit, as shown in the following relationship (6):

[0092]

[0093] In the formula: P H,t P represents the hydrogen production power at time t, which is also the operating power. Hmax The maximum hydrogen production power is represented by the following relationship (7); P Hmin The minimum hydrogen production power is represented by the following relationship (8); P′ H,t Let P represent the hydrogen production power at time t, as shown in equation (9); Hs This indicates the hot standby power of the hydrogen production system.

[0094] P Hmax =I H ·F Hmax (7)

[0095] P Hmin =I H ·F Hmin (8)

[0096]

[0097] In the formula: P A,t I represents the ammonia synthesis power at time t; H Indicates the installed capacity of hydrogen production facilities; F Hmax Indicates the maximum hydrogen production capacity range; F Hmin Indicates the minimum hydrogen production power range; E H Indicates the energy consumption per unit of hydrogen production; H S,t-1 H represents the amount of hydrogen stored at time t-1; SC Indicates the rated hydrogen storage capacity; η HS Indicates the hydrogen storage adjustment factor; H A,t This represents the rate at which hydrogen is consumed in the synthesis of ammonia at time t.

[0098] Furthermore, the hydrogen production rate at time t can also be calculated, as shown in the following equation (10):

[0099]

[0100] In the formula: H P,t This represents the hydrogen production rate at time t.

[0101] Specifically, in the water electrolysis hydrogen production unit, the hydrogen production rate can affect the operating power through system feedback mechanisms, equipment operating efficiency, and energy balance requirements, which in turn can affect the renewable energy consumption ratio of the renewable energy hydrogen production to ammonia synthesis coupled with hydrogen power generation system.

[0102] Furthermore, the hydrogen storage capacity H at time t can also be calculated. S,t The following relation (11) is shown:

[0103] H S,t =H S,t-1 +H P,t -H A,t -H HP,t (11)

[0104] In the formula: H HP,t This represents the rate at which hydrogen is consumed in hydrogen power generation at time t.

[0105] Specifically, hydrogen storage capacity can be affected by P′ H,t This, in turn, affects hydrogen production capacity, and further, it can affect the proportion of renewable energy consumption in renewable energy-to-hydrogen-ammonia-synthetic-hydrogen-power-generation systems.

[0106] Furthermore, hydrogen storage capacity also influences the operational decisions of hydrogen fuel cell power generation units. When hydrogen storage is sufficient, the hydrogen fuel cell power generation unit can generate electricity more flexibly according to system demand, resulting in variations in its power output. These variations in power output, in turn, affect the calculation of the renewable energy consumption ratio by influencing the system's power balance.

[0107] Step a32: Based on the renewable energy power generation power relationship, the installed power value of the hydrogen fuel cell power generation unit and the operation model, establish the second operating power relationship of the hydrogen fuel cell power generation unit.

[0108] Specifically, the second operating power relationship is shown in the following equation (12):

[0109] P HP,t =max(P H,t +P A,t -P RE,t ,0) (12)

[0110] In the formula: P HP,t E represents the hydrogen power generation capacity at time t. HP This indicates the amount of electricity generated per unit of hydrogen gas.

[0111] Furthermore, P HP,t The range is shown in the following relation (13):

[0112] P HPmin ≤P HP,t ≤P HPmax (13)

[0113] In the formula: P HPmin The minimum hydrogen power generation capacity is represented by the following relationship (14); P HPmaxThe maximum hydrogen power generation capacity is represented by the following relationship (15).

[0114] P HPmax =I HP ·F HPmax (14)

[0115] P HPmin =I HP ·F HPmin (15)

[0116] In the formula: I HP This indicates the installed capacity of hydrogen power generation.

[0117] Furthermore, the hydrogen consumption rate of the hydrogen power generation unit is shown in the following equation (16):

[0118] H HP,t =P HP,t / E HP (16)

[0119] Specifically, the rate at which hydrogen is consumed in hydrogen power generation can affect the operating power of hydrogen fuel cell power generation units, and in turn, the proportion of renewable energy consumption in renewable energy-to-hydrogen-ammonia-synthetic-hydrogen-power-generation systems.

[0120] Step a33: Based on the renewable energy power generation relationship, the installed power value of the electrochemical energy storage unit and the operation model, establish the third operating power relationship of the electrochemical energy storage unit.

[0121] Specifically, the third operating power relationship is shown in the following equations (17) to (19):

[0122] P Bdischa,t =min(max(max(P) H,t +P A,t -P RE,t ,0)-P HP,t ,0),I B (17)

[0123] P Bcha,t =min(max(P) RE,t -P H,t -P A,t ,0),I B (18)

[0124]

[0125] In the formula: P Bdischa,t I represents the energy storage discharge power at time t; B P represents the installed capacity of energy storage; Bcha,t B represents the energy storage charging power at time t;t η represents the energy storage charge capacity at time t; B Indicates the energy storage charging and discharging efficiency; B max This indicates the installed capacity of energy storage.

[0126] Step a34: Based on the renewable energy power generation power relationship, the first operating power relationship, the second operating power relationship, and the third operating power relationship, establish the fourth operating power relationship for the ammonia synthesis unit.

[0127] Specifically, by comprehensively considering the operating characteristics and interrelationships of each key unit in the system and establishing the operating power relationship between each unit in the renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system, it is possible to deeply analyze the power interaction and energy flow between different units. In subsequent capacity optimization, the scale of each unit can be adjusted more precisely, enabling the system to achieve efficient and stable operation under various operating conditions, maximizing the proportion of renewable energy consumption, and meeting the needs of safe production in hydrogen production and ammonia synthesis.

[0128] In some alternative implementations, step a34 above includes:

[0129] Step a341: Determine the power range for ammonia synthesis based on the renewable energy power generation relationship, the first operating power relationship, the second operating power relationship, and the third operating power relationship.

[0130] First, based on the range F of ammonia synthesis power generated by renewable energy power generation. A ′ ,t The following relation (20) is shown:

[0131]

[0132] In the formula: ΔF A Indicates the hourly ammonia synthesis adjustment ratio; F Amin Indicates the minimum ammonia synthesis power range; F Amax Indicates the maximum ammonia synthesis power range; P REmax α represents the maximum renewable energy power generation; α represents the segmentation coefficient of renewable energy power generation calculated based on the synthetic ammonia adjustment ratio, as shown in the following relationship (21); N represents the number of segments of renewable energy power generation calculated based on the synthetic ammonia adjustment ratio, as shown in the following relationship (22).

[0133] α=ΔF A / (F Amax -F Amin +ΔF A ) (twenty one)

[0134] N = 1, 2, ..., (FAmax -F Amin -ΔF A ) / ΔF A (twenty two)

[0135] Secondly, the range of ammonia synthesis power is adjusted according to the hydrogen storage capacity and hydrogen power generation capacity, as shown in the following equations (23) to (25):

[0136]

[0137] In the formula: F A,t This represents the range of ammonia synthesis power after adjustment at time t; This indicates the range of ammonia synthesis power adjusted based on hydrogen storage capacity; η HSU Indicates the upper limit coefficient for hydrogen storage regulation; η HSL Indicates the lower limit coefficient for hydrogen storage regulation; H SCmin Indicates the minimum hydrogen storage capacity; This indicates the range of ammonia synthesis power adjusted based on hydrogen power generation capacity; P Amin This represents the minimum ammonia synthesis power.

[0138] Finally, the power range for ammonia synthesis can be constrained based on the load regulation rate and the need to ensure the safety of key infrastructure, as shown in the following equations (26) to (28):

[0139] F A,t-1 -ΔF A ≤F A,t ≤F A,t-1 +ΔF A (26)

[0140] F As ≤F A,t ≤F Amax (27)

[0141] F As <F Amin (28)

[0142] In the formula: F As This indicates the minimum power range required to ensure the safety of key basic equipment in the ammonia synthesis system.

[0143] Step a342: Establish a second operating power relationship based on the ammonia synthesis power range.

[0144] Specifically, the second operating power relationship is shown in the following equation (29):

[0145]

[0146] In the formula: I A This indicates the installed capacity of the ammonia synthesis plant.

[0147] Furthermore, since the rate of hydrogen consumption in ammonia synthesis affects the ammonia synthesis power, it is also necessary to calculate the rate of hydrogen consumption in ammonia synthesis of the ammonia synthesis unit, as shown in the following relationship (30):

[0148]

[0149] In the formula: η HA E represents the hydrogen-ammonia mass conversion factor. A This indicates the energy consumption per unit of ammonia synthesis.

[0150] Specifically, the rate at which hydrogen is consumed in ammonia synthesis can affect the operating power of the ammonia synthesis unit, which in turn can affect the renewable energy consumption ratio of the renewable energy-to-hydrogen-ammonia-coupled-hydrogen-power-generation system.

[0151] Step S2022: With the goal of maximizing the renewable energy consumption ratio of the renewable energy-to-hydrogen-to-ammonia-synthetic-hydrogen-power-generation system, an objective function is established based on the operating power relationship of each unit.

[0152] Specifically, the objective function is used to characterize the proportion of renewable energy consumption in the renewable energy-to-hydrogen-to-ammonia-synthetic-hydrogen-power-generation system.

[0153] Furthermore, the proportion of renewable energy consumption is shown in the following equation (31):

[0154]

[0155] In the formula: RC represents the renewable energy consumption ratio.

[0156] Step S203: Based on multiple initial installed capacity values, the objective function is solved using the particle swarm optimization algorithm to obtain the capacity configuration optimization results of the renewable energy hydrogen production and ammonia synthesis coupled with hydrogen power generation system. For details, please refer to [link to relevant documentation]. Figure 1 Step S103 of the illustrated embodiment will not be described again here.

[0157] The capacity configuration optimization method provided in this embodiment establishes a renewable energy power generation relationship between renewable energy power generation units by combining the initial installed capacity scale and installed power values. This takes into account the performance parameters of the equipment itself and the impact of external environmental factors on power generation, thus more accurately reflecting the power output characteristics of the renewable energy power generation units. Furthermore, by comprehensively considering the operating characteristics and interrelationships of each key unit in the system and establishing operating power relationships between each unit within the renewable energy hydrogen production / ammonia synthesis coupled hydrogen power generation system, it is possible to deeply analyze the power interaction and energy flow between different units. This allows for more precise adjustment of the scale of each unit during subsequent capacity configuration optimization, enabling the system to achieve efficient and stable operation under various operating conditions, maximizing the proportion of renewable energy consumption, and simultaneously meeting the safety requirements of hydrogen production and ammonia synthesis chemical production. Furthermore, establishing an objective function based on the operating power relationships of each unit allows the objective function to more accurately reflect the system's operating characteristics and optimization requirements, providing support for more effectively guiding the algorithm to find the optimal capacity configuration scheme.

[0158] This embodiment provides a capacity configuration optimization method for controlling a system that is connected to a renewable energy-based hydrogen production and ammonia synthesis coupled hydrogen power generation system.

[0159] Figure 3 This is a flowchart of a capacity configuration optimization method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0160] Step S301: Obtain multiple operating models and multiple initial installed capacity values ​​for a renewable energy-to-hydrogen-to-ammonia-synthetic-hydrogen-power-generation system. For details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0161] Step S302: With the goal of maximizing the renewable energy consumption ratio of the renewable energy-to-hydrogen-to-ammonia-synthetic-hydrogen-power-generation system, an objective function is established based on multiple operating models and multiple initial installed capacity values. For details, please refer to [link to relevant documentation]. Figure 2 Step S202 of the illustrated embodiment will not be described again here.

[0162] Step S303: Based on multiple initial installed capacity values, the objective function is solved using the particle swarm optimization algorithm to obtain the capacity configuration optimization results of the renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system.

[0163] Specifically, step S303 includes:

[0164] Step S3031: Based on multiple initial installed capacity values, the objective function is solved using the particle swarm optimization algorithm to obtain multiple target installed capacity values ​​for the renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system.

[0165] Specifically, multiple initial installed capacity values ​​can be used as initial particles in the particle swarm. Each particle represents a combination of installed capacity from various units (such as renewable energy power generation units, water electrolysis hydrogen production units, ammonia synthesis units, hydrogen fuel cell power generation units, electrochemical energy storage units, etc.) in a renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system. Simultaneously, a velocity is randomly initialized for each particle, which determines the particle's direction of movement and step size in the search space.

[0166] Furthermore, the fitness value corresponding to each particle can be calculated based on the objective function.

[0167] The fitness value reflects the merits of the combination of installed capacity represented by the particle in maximizing the proportion of renewable energy consumption.

[0168] Furthermore, update the individual extrema, global extrema, particle velocity, and position:

[0169] (1) Update individual extreme values: For each particle, compare its current fitness value with the best fitness value in its own history. If the current fitness value is better, update the individual extreme value of the particle, that is, record the current equipment size combination as the best position of the particle.

[0170] (2) Update the global extremum: Compare the fitness values ​​of all particles and find the particle with the highest fitness value. The corresponding equipment size combination is the current global extremum. Furthermore, the global extremum represents the optimal equipment size configuration found for the entire particle swarm.

[0171] (3) Update particle velocity and position: The velocity and position of particles can be updated according to the velocity update formula and position update formula of the particle swarm algorithm.

[0172] Furthermore, the steps of calculating fitness values ​​and updating particle velocities and positions are repeated multiple times. After each iteration, it is checked whether the termination condition is met, such as reaching the preset maximum number of iterations or the change in fitness values ​​being less than a certain threshold. If the termination condition is met, the iteration stops, and the multiple particle positions obtained in the particle swarm at this point represent the multiple target device size values.

[0173] Step S3032: Determine the capacity configuration optimization result of the renewable energy hydrogen production and ammonia synthesis coupled hydrogen power generation system based on multiple target installed capacity values.

[0174] Specifically, for the multiple target installed capacity values ​​obtained from the calculation, their corresponding fitness values ​​can be calculated again based on the objective function.

[0175] Furthermore, by comparing the fitness values ​​of all target installed capacity values, the target installed capacity value with the highest fitness value can be identified.

[0176] Furthermore, the combination of the installed capacity of each unit represented by the target installed capacity value is the capacity configuration optimization result of the renewable energy hydrogen production and ammonia synthesis coupled with hydrogen power generation system.

[0177] Furthermore, in some optional implementations, the obtained capacity configuration optimization results can be further verified and adjusted. For example, it can be checked whether the configuration meets other system constraints, such as physical limitations of the equipment, cost budget, and security requirements. If certain constraints are not met, it may be necessary to adjust the results appropriately or recalculate the optimization.

[0178] The capacity configuration optimization method provided in this embodiment utilizes the efficient search and optimization capabilities of the particle swarm optimization algorithm to quickly search for the combination of installed capacity that maximizes the renewable energy consumption ratio within a vast space of installed capacity combinations and determine the final capacity configuration optimization result. This enables the system to achieve efficient energy utilization and stable operation in off-grid mode, thereby improving the renewable energy consumption ratio.

[0182] (3) Taking the highest renewable energy consumption ratio as the optimization objective, and using the installed capacity of each unit in the system, such as renewable energy, water electrolysis hydrogen production, synthetic ammonia, hydrogen fuel cell power generation, and electrochemical energy storage, as variables, the particle swarm algorithm is used to solve for the optimal capacity configuration scheme of the renewable energy hydrogen production and synthetic ammonia coupled hydrogen power generation system.

Renewable energy power generation supplies the water electrolysis hydrogen production unit and the ammonia synthesis unit, which have a certain degree of flexible response capability. The hydrogen fuel cell power generation unit provides backup power for the entire system when renewable energy power is scarce. The hydrogen produced by the hydrogen production unit is stored in the hydrogen storage unit and then supplied to the ammonia synthesis unit and the hydrogen fuel cell power generation unit. The electrochemical energy storage unit is used to smooth the output of renewable energy power generation and provide a portion of backup power.

[0185] Furthermore, the calculations corresponding to steps (1) to (3) are as shown in the above relations (1) to (31).

[0186] The capacity configuration optimization method for a renewable energy hydrogen production and ammonia synthesis coupled with hydrogen power generation system provided in this example has the following effects:

[0187] (1) By optimizing the operation method of the renewable energy hydrogen production and ammonia synthesis coupled with hydrogen power generation system, efficient energy utilization and stable system operation in off-grid mode can be achieved;

[0188] (2) Based on the interlocking operation of each unit of the system, and based on the flexible and corresponding hydrogen production unit and ammonia synthesis unit, the optimal installed capacity of each unit such as renewable energy, water electrolysis hydrogen production, ammonia synthesis, hydrogen fuel cell power generation, hydrogen storage, and electrochemical energy storage is solved by particle swarm algorithm, which effectively promotes the consumption of renewable energy in the off-grid system.
