[0049] Within any second preset length period, for any third preset length period within the second preset length period, the actual operating status of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system within the third preset length period can be determined based on the real-time hydrogen inventory of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system within the third preset length period, and then the simulated ammonia production power within the third preset length period can be corrected and adjusted in real time to determine the real-time ammonia production power of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system within the third preset length period.

[0090] Specifically, the normal operating condition may indicate that the target renewable energy water electrolysis hydrogen production ammonia synthesis system operates at a simulated ammonia production power. The hydrogen replenishment storage capacity operating condition may indicate that the target renewable energy water electrolysis hydrogen production ammonia synthesis system operates at a minimum ammonia production power. At this time, the ammonia synthesis unit of the target renewable energy water electrolysis hydrogen production ammonia synthesis system is usually in hot standby mode to reduce the hydrogen consumption of the ammonia synthesis unit and increase the real-time hydrogen inventory. The dehydrogenation storage capacity operating condition may indicate that the target renewable energy water electrolysis hydrogen production ammonia synthesis system operates at a maximum ammonia production power. At this time, the ammonia synthesis unit of the target renewable energy water electrolysis hydrogen production ammonia synthesis system is usually in a high operating mode to increase the hydrogen consumption of the ammonia synthesis unit and reduce the real-time hydrogen inventory.

[0091] The operating adjustment conditions corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system can be used to indicate whether the ammonia synthesis unit of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system needs to adjust its operating status.

For example, the dehydrogenation trigger condition can be set as: the real-time hydrogen inventory is greater than or equal to 100% of the hydrogen storage medium capacity, etc. The present disclosure does not make specific limitations on this.

[0096] The dehydrogenation recovery condition can be used to indicate that the target renewable energy water electrolysis hydrogen production and ammonia synthesis system is adjusted from the dehydrogenation storage capacity operating condition to the normal operating condition. The specific content can be flexibly set according to actual usage requirements. For example, the dehydrogenation recovery condition can be set to: the real-time hydrogen inventory is less than or equal to 50% of the hydrogen storage medium capacity, etc. The present disclosure does not make specific limitations on this.

[0097] For any third preset length period, the real-time ammonia synthesis condition of the target renewable energy water electrolysis hydrogen production ammonia synthesis system within the third preset length period can be determined based on the ammonia synthesis condition of the previous period of the third preset length period, the real-time hydrogen inventory, and the corresponding operating condition adjustment conditions of the target renewable energy water electrolysis hydrogen production ammonia synthesis system.

[0098] Figure 2 FIG. 4 is a flow chart showing a hysteresis control strategy according to an embodiment of the present disclosure. Figure 2 As shown, when the ammonia synthesis condition in the previous time period is the hydrogen storage capacity replenishment condition, it can be determined whether the ammonia synthesis condition of the target renewable energy water electrolysis hydrogen production ammonia synthesis system needs to be adjusted within the third preset length period based on the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system and the condition adjustment conditions.

[0099] Specifically, when the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system meets the hydrogen replenishment recovery conditions, the real-time ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system is restored to the normal operating condition within the third preset length period.

[0100] When the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system does not meet the hydrogen replenishment recovery conditions, within the third preset length period, the real-time ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system is determined to maintain the hydrogen replenishment storage capacity condition.

[0101] When the ammonia synthesis operating condition in the previous time period is normal, it can be determined whether it is necessary to adjust the ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production ammonia synthesis system within the third preset length period based on the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system and the operating condition adjustment conditions.

[0102] Specifically, when the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system meets the hydrogen replenishment trigger condition, the real-time ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production ammonia synthesis system is adjusted to the hydrogen replenishment storage capacity operating condition within the third preset length period; when the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system meets the dehydrogenation trigger condition, the real-time ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production ammonia synthesis system is adjusted to the dehydrogenation storage capacity operating condition within the third preset length period; when the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system meets neither the hydrogen replenishment trigger condition nor the dehydrogenation trigger condition, within the third preset length period, it is determined that the real-time ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production ammonia synthesis system maintains the normal operating condition.

[0103] When the ammonia synthesis operating condition in the previous time period is the dehydrogenation storage capacity operating condition, it can be determined whether the ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production ammonia synthesis system needs to be adjusted within the third preset length period based on the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system and the operating condition adjustment conditions.

[0104] Specifically, when the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system meets the dehydrogenation recovery conditions, the real-time ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system is restored to normal operating condition within the third preset length period.

[0105] When the real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system does not meet the dehydrogenation recovery conditions, within the third preset length period, the real-time ammonia synthesis operating condition of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system is determined to maintain the dehydrogenation storage capacity operating condition.

[0106] For any third preset length period, after using the above process to determine the real-time ammonia synthesis operating conditions of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system within the third preset length period, the simulated ammonia production power can be combined to determine the real-time ammonia production power of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system within the third preset length period.

[0107] Furthermore, in addition to adjusting the operating state of the ammonia synthesis unit of the target renewable energy water electrolysis hydrogen production ammonia synthesis system, the hysteresis control strategy can also make other adjustments to the target renewable energy water electrolysis hydrogen production ammonia synthesis system to achieve overall coordinated optimization of the system and improve control efficiency.

[0108] With the above Figure 2 For example, Figure 2As shown, after determining the operating status of the ammonia synthesis unit of the target renewable energy water electrolysis hydrogen synthesis system, the operating status of its renewable energy power generation unit and water electrolysis hydrogen synthesis unit can be adjusted respectively to reduce the abandoned electricity and off-grid sales electricity of the target renewable energy water electrolysis hydrogen synthesis system.

[0109] Through the above process, the real-time hydrogen inventory can be used as a control signal to fully utilize the buffering capacity and flexibility of hydrogen inventory management, to perform hysteresis control on the ammonia synthesis unit of the target renewable energy water electrolysis hydrogen production ammonia synthesis system, and to adaptively adjust the ammonia synthesis conditions of the ammonia synthesis unit, thereby achieving timing coordinated optimization of chemical production operations and improving the stability and reliability of the target renewable energy water electrolysis hydrogen production ammonia synthesis system.

[0110] Figure 3 A timing diagram showing a coordinated control method of a renewable energy water electrolysis hydrogen synthesis ammonia system according to an embodiment of the present disclosure. Figure 3 As shown in the figure, based on the predicted power generation corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system, the day-ahead plan optimization can be performed to determine the simulated hydrogen production power of the target renewable energy water electrolysis hydrogen production ammonia synthesis system within 15 minutes on January 1, and the simulated ammonia production power within 8 hours on January 1. From 0:15 on January 1, the simulated hydrogen production power can be corrected in real time according to the real-time power generation corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system with a 15-minute adjustment window; at the same time, based on the real-time hydrogen inventory in the hydrogen storage medium, the ammonia synthesis condition can be hysteresis controlled with a 15-minute operating condition adjustment window until 24:00 on January 1. At 24:00 on January 1, the corresponding end-of-day hydrogen inventory and ammonia inventory on January 1 can be determined as a reference for the coordinated control of the target renewable energy water electrolysis hydrogen production ammonia synthesis system on January 2, and the above-mentioned coordinated control process is repeated on January 2.

[0111] In a possible implementation, the method further includes: based on a preset inspection cycle, performing an inventory inspection on the target renewable energy water electrolysis hydrogen production and ammonia synthesis system, and determining the ammonia inventory of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system in each inspection cycle; for any inspection cycle, determining the ammonia retail trading decision corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system based on the ammonia inventory of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system in the inspection cycle and the target schedulable domain, wherein the target schedulable domain is used to reflect the scheduling capacity of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system for the inventory of ammonia, and the ammonia retail trading decision includes the ammonia retail amount of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system in the inspection cycle.

[0112] The specific value of the inspection cycle here can be flexibly set according to actual usage needs and depends on the transaction cycle of ammonia retail. For example, inventory inspection can be set once a week, etc. This disclosure does not make specific limitations on this.

[0113] The target dispatchable domain can be used to reflect the dispatching capacity of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system for the stored ammonia. Its specific value can be flexibly set according to actual usage needs, and is usually affected by factors such as the preset ammonia inventory management target, the capacity of the ammonia storage medium, and the long-term contract ammonia trading demand corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system. The present disclosure does not make specific limitations on this.

[0114] In a possible implementation, the method also includes: determining an initial dispatchable domain of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system in each inspection cycle according to a preset ammonia inventory management target; for any inspection cycle, determining a target dispatchable domain of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system in the inspection cycle according to the initial dispatchable domain of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system in the inspection cycle and the ammonia inventory capacity corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system.

[0115] The ammonia inventory management target here may include the maximum and minimum ammonia inventory corresponding to the ammonia storage medium in each inspection cycle, etc., which can be flexibly set according to actual usage requirements, and the present disclosure does not make specific limitations on this.

[0116] In one example, for any inspection period w, the initial dispatchable domain of the target renewable energy water electrolysis hydrogen production ammonia synthesis system within the inspection period w can be determined according to the ammonia inventory management target within the inspection period w. Specifically, the initial dispatchable domain corresponding to any time within the inspection period w can be expressed as formula (14):

[0117]

[0118] Among them, F W It represents the initial dispatchable domain corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system at time W; It represents the ammonia inventory corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system at time W; It represents the lower boundary of the initial dispatchable domain corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system at time W; It represents the upper boundary of the initial dispatchable domain corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system at time W.

[0119] Let w←W-1. When w is greater than 0, according to the capacity constraint of the ammonia storage medium, the surface representation of the initial dispatchable domain can be determined as formula (15):

[0120]

[0121] Among them, Q w A surface representation of the schedulable domain; It represents the ammonia inventory at any time within the inspection period w.

[0122] Using the dual representation, the surface representation of the initial schedulable domain can be converted into a vertex representation. The vertex representation of the initial schedulable domain can be expressed as formula (16):

[0123] q w ←υertex(Q w ) (16)

[0124] Among them, q w represents the vertex representation of the schedulable domain; υertex(·) represents all vertices of the surface representation.

[0125] According to the prediction interval of renewable energy power generation corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system, the surface representation of the prediction interval can be initialized. The surface representation of the prediction interval can be expressed as formula (17):

[0126] P w+1 ←Ω w+1 (17)

[0127] Among them, P w+1 The surface representation of the forecast interval of renewable energy power generation; Ω w+1 The uncertain set representing the output of renewable energy generators.

[0128] Using the dual representation, the face representation of the prediction interval can be converted into vertex representation. The vertex representation of the prediction interval can be expressed as formula (16):

[0129] p w+1 ←υertex(P w+1 ) (18)

[0130] Among them, p w+1 Vertex representation representing the forecast interval for renewable energy generation.

[0131] Based on formula (16) and formula (18), an augmented vertex set can be constructed. The augmented vertex set can be expressed as formula (19):

[0132]

[0133] Among them, U represents the augmented vertex set.

[0134] When the augmented vertex set is not an empty set, the linear programming problem can be solved for any vertex in the augmented vertex set. w ,ξ′ w+1 ), the linear programming problem can be expressed as formula (20):

[0135]

[0136] Among them, u w represents the vertex to be solved; J represents the objective function to minimize the sum of slack variables; s represents the slack variable; A, B, C, D are constant matrices; x w+1 Indicates the state quantity at the next moment; u w+1 represents the control variable at the next moment; b w+1 is a constant vector; λ represents the Lagrange multiplier; F w+1 Indicates the schedulable domain at the next moment.

[0137] When J is greater than 0, the inequality cut to the surface representation of the initial schedulable domain can be added to obtain formula (21):

[0138] Q w ←Q w ∪{λ T (Cx w -b w+1 )≤0} (21)

[0139] Then, formula (16) and formula (19) can be updated.

[0140] When J is less than or equal to 0, we can get U←U / {(x′ w ,ξ′ w+1 )}.

[0141] Based on the above solution process, it can be determined that within the inspection period w, the target dispatchable domain of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system is F w =Q w , w←w-1.

[0142] After determining the ammonia inventory of the target renewable energy water electrolysis hydrogen production ammonia synthesis system in any inspection cycle, the ammonia retail transaction decision of the target renewable energy water electrolysis hydrogen production ammonia synthesis system in the inspection cycle can be determined in combination with the preset target schedulable domain, and the ammonia retail volume of the target renewable energy water electrolysis hydrogen production ammonia synthesis system in the inspection cycle can be adjusted. Among them, the specific method of determining the ammonia retail transaction decision can be flexibly set according to actual usage needs, and this disclosure does not make specific limitations on this.

[0143] Figure 4A schematic diagram of an ammonia retail transaction decision according to an embodiment of the present disclosure is shown. Figure 4 As shown, for any inspection period, when the ammonia inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system is greater than the upper boundary of the target dispatchable domain within the period, it means that the target renewable energy water electrolysis hydrogen production ammonia synthesis system is expected to meet the ammonia trading demand of the long-term contract within the inspection period, and the ammonia inventory may overflow, and the ammonia retail volume should be increased; when the ammonia inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system is less than the lower boundary of the target dispatchable domain within the period, it means that the target renewable energy water electrolysis hydrogen production ammonia synthesis system is expected to be unable to meet the ammonia trading demand of the long-term contract within the inspection period, and the ammonia retail volume should be reduced; when the ammonia inventory corresponding to the target renewable energy water electrolysis hydrogen production ammonia synthesis system is within the target dispatchable domain within the period, it means that the target renewable energy water electrolysis hydrogen production ammonia synthesis system is expected to meet the ammonia trading demand of the long-term contract within the inspection period, and the ammonia retail volume can be kept unchanged.

[0144] The above process can be expressed as formula (22):

[0145]

[0146] Among them, u w represents the ammonia retail transaction decision; u Inc Indicates the increase of ammonia retail transaction decision; u Rem Indicates that the ammonia retail trading decision is maintained; Dec Represents a reduction in ammonia retail trading decisions; represents the upper boundary of the target schedulable domain; Indicates the amount of ammonia inventory; Represents the lower boundary of the target schedulable region.

[0147] By adopting a periodic inventory inspection strategy based on ammonia storage levels, ammonia inventory management can be carried out for the target renewable energy water electrolysis hydrogen production ammonia synthesis system from the perspective of market scheduling. While ensuring that the ammonia trading needs of long-term contracts are met, the safety risks of excessive ammonia inventory can be reduced, the reliability and safety of system operation can be improved, and the system revenue can be further increased by flexibly adjusting the ammonia retail strategy.

[0148] In the embodiment of the present disclosure, based on the predicted power generation corresponding to the target renewable energy source water electrolysis hydrogen production and ammonia synthesis system, the day-ahead plan optimization of the target renewable energy source water electrolysis hydrogen production and ammonia synthesis system can be achieved, and the full-day multi-period simulated hydrogen production power including the simulated hydrogen production power of the target renewable energy source water electrolysis hydrogen production and ammonia synthesis system in each first preset length period within a single day, and the full-day multi-period simulated ammonia production power including the simulated hydrogen production power of the target renewable energy source water electrolysis hydrogen production and ammonia synthesis system in each second preset length period within a single day are determined, which can provide a basis for the coordinated control of the target renewable energy source water electrolysis hydrogen production and ammonia synthesis system within a single day, thereby improving the reliability of the coordinated control and improving the control efficiency. By real-time monitoring of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system, the real-time power generation power and real-time hydrogen inventory corresponding to the target renewable energy water electrolysis hydrogen production and ammonia synthesis system are determined, and according to the real-time power generation power and real-time hydrogen inventory, real-time correction and adjustment are made to the simulated hydrogen production power for multiple periods throughout the day and the simulated ammonia production power for multiple periods throughout the day, and the real-time ammonia production power for multiple periods throughout the day including the real-time hydrogen production power of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system in each first preset length period within a single day, and the real-time ammonia production power of multiple periods throughout the day including the real-time ammonia production power of the target renewable energy water electrolysis hydrogen production and ammonia synthesis system in each third preset length period within a single day are determined, and the buffering capacity and flexibility of hydrogen and ammonia inventory management are fully utilized to perform closed-loop control and hysteresis control on the target renewable energy water electrolysis hydrogen production and ammonia synthesis system on multiple time scales, so as to achieve coordinated optimization of power generation and utilization balance and chemical production operation sequence, and flexibly adjust ammonia retail trading decisions, reduce the abandonment rate of renewable energy, and improve energy utilization and system benefits.
