As shown in FIG. 1, the target renewable energy water electrolysis hydrogen synthesis ammonia system can be divided into a renewable energy generator unit, a water electrolysis hydrogen synthesis unit and an ammonia synthesis unit.

[0111] In a possible implementation, the method further includes: based on a preset inspection period, performing inventory inspection on the target renewable energy water electrolysis hydrogen synthesis ammonia system to determine the ammonia inventory of the target renewable energy water electrolysis hydrogen synthesis ammonia system within each inspection period; for any one inspection period, determining the ammonia retail transaction decision corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system according to the ammonia inventory of the target renewable energy water electrolysis hydrogen synthesis ammonia system within the inspection period and a target schedulable domain, wherein the target schedulable domain is used to reflect the scheduling capability of the target renewable energy water electrolysis hydrogen synthesis ammonia system for the inventory ammonia, and the ammonia retail transaction decision includes the ammonia retail quantity of the target renewable energy water electrolysis hydrogen synthesis ammonia system within the inspection period.
[0112] The specific value of the inspection period can be flexibly set according to actual use requirements, and depends on the transaction period of ammonia retail, for example, the inventory inspection can be performed once a week, and the present disclosure does not make specific limitations in this regard.
[0113] The target schedulable domain can be used to reflect the scheduling capability of the target renewable energy water electrolysis hydrogen synthesis ammonia system for ammonia in inventory, and the specific value can be flexibly set according to actual use requirements, 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 transaction demand corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system, and the present disclosure does not make specific limitations in this regard.
[0114] In one possible implementation, the method further includes: determining the initial schedulable domain of the target renewable energy water electrolysis hydrogen synthesis ammonia system in each inspection period according to the preset ammonia inventory management target; and determining the target schedulable domain of the target renewable energy water electrolysis hydrogen synthesis ammonia system in each inspection period according to the initial schedulable domain of the target renewable energy water electrolysis hydrogen synthesis ammonia system in the inspection period and the ammonia inventory capacity corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system.
[0115] The ammonia inventory management target can include the maximum and minimum values of the ammonia inventory corresponding to the ammonia storage medium in each inspection period, and can be flexibly set according to actual use requirements, and the present disclosure does not make specific limitations in this regard.
[0116] In an example, for any inspection period w, the initial schedulable domain of the target renewable energy water electrolysis hydrogen synthesis ammonia system in the inspection period w can be determined according to the ammonia inventory management target in the inspection period w. Specifically, the initial schedulable domain corresponding to any time in the inspection period w can be represented by formula (14):
[0117]
[0118] wherein F W represents the initial schedulable domain corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system at time W; represents the ammonia inventory corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system at time W; represents the lower boundary of the initial schedulable domain corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system at time W; represents the upper boundary of the initial schedulable domain corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system at time W.
[0119] Let w←W-1, and under the condition that w is greater than 0, the surface representation of the initial schedulable domain can be determined according to the capacity constraint of the ammonia storage medium, and is represented by formula (15):
[0120]
[0121] wherein Q w represents the face representation of the schedulable domain; represents the ammonia inventory at any time within the checking period w.
[0122] By using the dual representation, the face representation of the initial schedulable domain can be converted into the vertex representation. The vertex representation of the initial schedulable domain can be represented by formula (16):
[0123] q w ←υertex(Q w ) (16)
[0124] wherein q w represents the vertex representation of the schedulable domain; υertex(·) represents all vertices of the face representation.
[0125] According to the prediction interval of the renewable energy power generation corresponding to the target renewable energy water electrolysis hydrogen synthesis ammonia system, the face representation of the prediction interval can be initialized. The face representation of the prediction interval can be represented by formula (17):
[0126] P w+1 ←Ω w+1 (17)
[0127] wherein P w+1 represents the face representation of the renewable energy power generation prediction interval; Ω w+1 represents the uncertainty set of the renewable energy generator unit output.
[0128] By using the dual representation, the face representation of the prediction interval can be converted into the vertex representation. The vertex representation of the prediction interval can be represented by formula (16):
[0129] p w+1 ←υertex(P w+1 ) (18)
[0130] wherein p w+1 represents the vertex representation of the renewable energy power generation prediction interval.
[0131] Based on formula (16) and formula (18), an augmented vertex set can be constructed, which can be represented by formula (19):
[0132]
[0133] wherein U represents the augmented vertex set.
[0134] In the case that the augmented vertex set is not empty, the linear programming problem can be solved for any vertex in the augmented vertex set. For the vertex (x' w , ξ' w+1 ), the linear programming problem can be expressed as formula (20):
[0135]
[0136] wherein u w represents the vertex to be solved; J represents that the objective function is the minimum sum of the slack variables; s represents the slack variable; A, B, C, D are constant matrices; x w+1 represents the state variable at the next time; u w+1 represents the control variable at the next time; b w+1 is a constant vector; λ represents the Lagrange multiplier; F w+1 represents the schedulable domain at the next time.
[0137] In the case that J is greater than 0, the inequality cut can be added to the face representation form of the initial schedulable domain to obtain formula (21):
[0138] Q w ← Q w ∪ {λ T (Cx w -b w+1 )≤0} (21)
[0139] Further, formula (16) and formula (19) can be updated.
[0140] In the case that J is less than or equal to 0, then U←U / {(x′ w , ξ′ w+1 )} can be obtained.
[0141] Based on the above solving process, it can be determined that the target schedulable domain of the target renewable energy water electrolysis hydrogen synthesis ammonia system within the inspection period w is F w = Q w , w←w-1.
[0142] After determining the ammonia inventory of the target renewable energy water electrolysis hydrogen synthesis ammonia system within any inspection period, the ammonia retail transaction decision of the target renewable energy water electrolysis hydrogen synthesis ammonia system within the inspection period can be determined in combination with the preset target schedulable domain, and the ammonia retail quantity of the target renewable energy water electrolysis hydrogen synthesis ammonia system within the inspection period is adjusted. The specific way of determining the ammonia retail transaction decision can be flexibly set according to actual use requirements, which is not limited in the present disclosure.
[0143] Figure 4A schematic diagram of an ammonia retail transaction decision according to an embodiment of the present disclosure is shown. As shown Figure 4 For any one check period, if the ammonia inventory corresponding to the target renewable energy electrolysis water hydrogen synthesis ammonia system in the period is greater than the upper boundary of the target dispatchable domain, it means that the target renewable energy electrolysis water hydrogen synthesis ammonia system is expected to meet the long-term contract ammonia transaction demand in the check period, and the ammonia inventory may overflow, and the ammonia retail quantity should be increased; if the ammonia inventory corresponding to the target renewable energy electrolysis water hydrogen synthesis ammonia system in the period is less than the lower boundary of the target dispatchable domain, it means that the target renewable energy electrolysis water hydrogen synthesis ammonia system is expected to be unable to meet the long-term contract ammonia transaction demand in the check period, and the ammonia retail quantity should be reduced; if the ammonia inventory corresponding to the target renewable energy electrolysis water hydrogen synthesis ammonia system in the period is within the target dispatchable domain, it means that the target renewable energy electrolysis water hydrogen synthesis ammonia system is expected to meet the long-term contract ammonia transaction demand in the check period, and the ammonia retail quantity can be kept unchanged.
[0144] The above process can be represented as formula (22):
[0145]
[0146] wherein u w represents an ammonia retail transaction decision; u Inc represents an increase in ammonia retail transaction decision; u Rem represents maintaining the ammonia retail transaction decision; u Dec represents reducing the ammonia retail transaction decision; represents the upper boundary of the target dispatchable domain; represents the ammonia inventory; represents the lower boundary of the target dispatchable domain.
[0147] By adopting the periodic inventory strategy based on the ammonia storage level, the ammonia inventory of the target renewable energy electrolysis water hydrogen synthesis ammonia system can be managed from the market dispatch level, while ensuring to meet the long-term contract ammonia transaction demand, reducing the safety risk of excessive ammonia inventory, improving the reliability and safety of system operation, and further improving the system revenue by flexibly adjusting the ammonia retail strategy.
