[0057] Step S202: determining an optimization target based on the clean energy abandoned power sequence.

[0058] Specifically, in order to maximize the reduction of the electricity cost of the clean energy abandoned electricity hydrogen production coupled with hydrogen liquefaction system, in this embodiment, the maximum utilization of the clean energy abandoned electricity is taken as the optimization goal, as shown in the following relationship (1):

[0059]

[0060] Where: m represents the total operation period of the clean energy abandoned electricity hydrogen production coupled with hydrogen liquefaction system; P a (t) represents the abandoned power of the clean energy abandoned power hydrogen production coupled with hydrogen liquefaction system at time t; P g (t) represents the power absorbed by the water electrolysis hydrogen production device in the clean energy abandoned electricity hydrogen production coupled with hydrogen liquefaction system at time t; P l (t) represents the power absorbed by the hydrogen liquefaction device in the clean energy power generation coupled hydrogen liquefaction system at time t.

[0062] Specifically, taking maximizing the utilization of clean energy curtailment as the optimization goal, the clean energy curtailment power sequence and operating power data set are used to solve the clean energy curtailment hydrogen production coupled with hydrogen liquefaction operation control model, and an operation control data set of the clean energy curtailment hydrogen production coupled with hydrogen liquefaction system that meets the preset constraint condition set can be obtained.

[0063] Step S204, based on the operation control data set, after being processed by a preset genetic algorithm, an operation control result of the clean energy abandoned electricity hydrogen production coupled with hydrogen liquefaction system is obtained.

[0064] The operation control method of the clean energy abandoned power hydrogen production coupled with hydrogen liquefaction system provided in this embodiment determines the optimization target based on the clean energy abandoned power power sequence. At the same time, under the constraint control of the preset constraint condition set, the operation control data set of the clean energy abandoned power hydrogen production coupled with hydrogen liquefaction system is obtained. Further, based on the preset genetic algorithm, the target operation control data of the clean energy abandoned power hydrogen production coupled with hydrogen liquefaction system is determined. Therefore, by implementing the present invention, the operation power of clean energy abandoned power hydrogen production and hydrogen liquefaction can be reasonably allocated, and the hydrogen storage and release process of the gas tank can be reasonably controlled, which effectively improves the safety and stability of the system operation and reduces the production cost of liquid hydrogen.

[0069] Among them, Figure 1 As shown, the clean energy abandoned electricity hydrogen production coupled with hydrogen liquefaction system 1 includes: a water electrolysis hydrogen production device 11, a hydrogen storage device 12 and a hydrogen liquefaction device 13.

[0070] Specifically, based on the randomness and volatility of clean energy power generation, its abandoned power also has uncertainty, resulting in the hydrogen output per unit time of the water electrolysis hydrogen production device 11 being unstable. In order to meet the stable operation conditions of the water electrolysis hydrogen production device 11 and the hydrogen liquefaction device 13, a hydrogen storage device 12 is added between the water electrolysis hydrogen production device 11 and the hydrogen liquefaction device 13 to store part of the hydrogen output by the water electrolysis hydrogen production device 11 as a cache, so that the clean energy abandoned power hydrogen production coupled with hydrogen liquefaction system 1 can meet the safe and stable operation conditions.

[0071] Furthermore, the operating power data set of the clean energy power-wasting hydrogen production coupled with hydrogen liquefaction system 1 may include a first operating power data set of the water electrolysis hydrogen production device 11 , a second operating power data set of the hydrogen storage device 12 , and a third power operating data set of the hydrogen liquefaction device 13 .

[0077] Step S302: Determine the optimization target based on the clean energy curtailment power sequence. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0078] Step S303, based on the clean energy power abandonment power sequence and the operating power data set, using the optimization goal and the preset constraint condition set, solve the clean energy power abandonment hydrogen production coupled with hydrogen liquefaction operation control model to obtain the clean energy power abandonment hydrogen production coupled with hydrogen liquefaction system operation control data set. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0079] Step S304: Based on the operation control data set, after being processed by a preset genetic algorithm, the operation control result of the clean energy abandoned power generation and hydrogen liquefaction system is obtained. Figure 2 Step S204 of the illustrated embodiment will not be described in detail here.

[0080] The operation control method of the clean energy abandoned power hydrogen production coupled with hydrogen liquefaction system provided in this embodiment comprehensively considers the characteristics of clean energy power generation, incorporates hydrogen liquefaction into the integrated configuration of clean energy grid-connected coupled hydrogen production, and cooperates with water electrolysis hydrogen production equipment and hydrogen storage devices to form a clean energy abandoned power hydrogen production coupled with hydrogen liquefaction system, filling the gap in the clean energy liquid hydrogen system.

[0081] In this embodiment, a method for controlling the operation of a clean energy abandoned electricity hydrogen production coupled with hydrogen liquefaction system is provided, wherein: Figure 1 As shown, the clean energy abandoned electricity hydrogen production coupled hydrogen liquefaction system 1 is connected to the clean energy monitoring system 2. Figure 4 : is a flow chart of an operation control method of a clean energy abandoned electricity hydrogen production coupled with hydrogen liquefaction system according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0082] Step S401, obtain the operating power data set of the clean energy abandoned power production and hydrogen liquefaction system and the clean energy abandoned power sequence sent by the clean energy monitoring system. Figure 3 Step S301 of the illustrated embodiment will not be described in detail here.

[0083] Step S402: Determine the optimization target based on the clean energy curtailment power sequence. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0084] Step S403: obtaining a preset constraint condition set.

[0085] The preset constraint condition set may include power balance constraints, energy conservation and mass conservation constraints, and device parameter constraints:

[0086] (1) Power balance constraint: The power curtailment of clean energy, the operating power of the water electrolysis hydrogen production device, and the operating power of the hydrogen liquefaction device must meet the power balance constraint, as shown in the following relationship (2):

The first hydrogen balance constraint: A portion of the hydrogen produced by the water electrolysis hydrogen production equipment is directly transported by pipeline to the hydrogen liquefaction device for liquefaction, and a portion is stored in a hydrogen storage device (such as a hydrogen storage tank, etc.). Therefore, the hydrogen input source of the hydrogen liquefaction device includes the hydrogen sent by the hydrogen storage device and part of the hydrogen produced by the water electrolysis hydrogen production device; at the same time, the abandoned electricity of clean energy is supplied to the two types of devices, water electrolysis hydrogen production and hydrogen liquefaction, and should meet the power balance and power balance conditions. Among them, the balance relationship between hydrogen and electric energy is as follows: Figure 5 shown.

[0096] Wherein: ΔV(t) represents the change in the amount of hydrogen in the hydrogen storage device at time t, wherein the hydrogen input of the hydrogen storage device is a positive value and the output is a negative value; V0 represents the amount of hydrogen in the hydrogen storage device at the initial moment.

[0097] C. Second hydrogen balance constraint: The total amount of hydrogen produced by water electrolysis and the total amount of liquefied hydrogen should also meet the mass balance condition, that is, the cumulative amount of hydrogen produced by water electrolysis is the sum of the current hydrogen storage capacity of the hydrogen storage device and the cumulative amount of liquefied hydrogen, as shown in the following relationship (5):

[0098]

[0099] (3) Equipment parameter constraints: To ensure the safe and stable operation of the system, the water electrolysis hydrogen production equipment and the hydrogen liquefaction equipment must meet the equipment's rated power range requirements and power change rate requirements. Therefore, the equipment parameter constraints may include water electrolysis hydrogen production device constraints, hydrogen liquefaction device constraints, and hydrogen storage device constraints:

[0100] A. Constraints of water electrolysis hydrogen production device: The water electrolysis hydrogen production device must meet the rated power range requirements of the equipment itself, as shown in the following relationship (6):

[0102] Where: Indicates the lower limit of the rated power of the water electrolysis hydrogen production device; Indicates the upper limit of the rated power of the water electrolysis hydrogen production device.

[0103] B. Hydrogen liquefaction unit constraints:

[0104] First, the hydrogen liquefaction device needs to meet the rated power range requirements of the equipment itself, as shown in the following relationship (7):

[0105]

[0106] Where: Indicates the lower limit of the rated power of the hydrogen liquefaction device; Indicates the upper limit of the rated power of the hydrogen liquefaction device.

[0107] Secondly, the hydrogen liquefaction device also needs to meet the power change rate requirement, as shown in the following equation (8):

[0108] |P l(t)-P l (t+1)|≤ΔP lmax (8)

[0109] Where: P lmax Indicates the maximum power change rate of the hydrogen liquefaction device.

[0110] C. Hydrogen storage device constraint: The amount of hydrogen stored in the hydrogen storage device must be less than the maximum storage capacity V of the hydrogen storage device. max .
