[0072] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0073] The electricity for the hydrogen production system can come from the power grid. Figure 1 , and can also come from new energy power generation systems (such as Figure 1 The new energy power generation system and / or the power grid supplies power to the hydrogen production unit in the hydrogen production system, so that the hydrogen production unit uses electrical energy to perform water electrolysis to produce hydrogen.
[0074] The power generation status of the new energy power generation system will affect the hydrogen production status of the hydrogen production unit. At present, the new energy power generation system is easily affected by environmental factors such as light intensity, wind force, temperature, humidity, etc., which makes the power generation of the new energy power generation system random and unstable. If the electric energy is directly connected to the electrolyzer of the hydrogen production unit, the fluctuating current and voltage of the input electric energy will cause the random drift of the electrolyzer working point, and the hydrogen production power of the electrolyzer may be large and small, and start and stop frequently, which will affect the mass transfer inside the electrolyzer, and affect the hydrogen production, life and efficiency of the electrolyzer. In other words, directly using the power generation parameters of the new energy power generation system, such as the power generation power to adjust the start and stop of the hydrogen production unit and the size of the hydrogen production power in real time, will reduce the life and hydrogen production efficiency of the hydrogen production unit.
[0075] To this end, the inventors have found through research that if the status of the hydrogen production units in the hydrogen production system in the previous cycle can be adjusted based on the target number and hydrogen production parameters of the hydrogen production units that should be in operation in the current cycle, the frequent start and stop of the hydrogen production units can be avoided. In order to solve the problem of large changes in hydrogen production power, if the target number and hydrogen production parameters of the hydrogen production units that should be in operation in the hydrogen production system in the current cycle can be determined based on the power generation parameters and the equipment parameters as a whole, the frequent start and stop of the hydrogen production units caused by the independent control of each hydrogen production system and the operation of all the operating hydrogen production units in the fluctuating power hydrogen production mode can be avoided. The problem of reduced system efficiency and life caused by the frequent start and stop of the hydrogen production units can be avoided.
[0076] Specifically, in the present invention, the target number and hydrogen production parameters of the hydrogen production units that should be in operation in the hydrogen production system in the current cycle, which correspond to the power generation parameters of the new energy power generation system and the equipment parameters of the hydrogen production units in the hydrogen production system, can be determined. When adjusting the state of the hydrogen production units in the hydrogen production system in the current cycle, in addition to considering the target number and hydrogen production parameters of the hydrogen production units that should be in operation in the current cycle, the state of the hydrogen production units in the hydrogen production system in the previous cycle will also be considered, that is, the state of the current cycle is determined from both the external situation and the internal situation of the hydrogen production unit, thereby avoiding the method of directly controlling the start and stop of the hydrogen production unit and the size of the hydrogen production power in real time according to the power generation parameters of the new energy power generation system, resulting in large changes in the hydrogen production power of the hydrogen production unit and frequent start and stop of the hydrogen production unit, thereby reducing the life of the hydrogen production unit and the hydrogen production efficiency.
[0077] Based on the above content, an embodiment of the present invention provides an operating state control method of a hydrogen production unit, which is applied to a controller in a hydrogen production system, referring to Figure 1 The hydrogen production system includes at least two hydrogen production units, each of which includes: a hydrogen production power supply and hydrogen production equipment, and the hydrogen production equipment includes a post-processing unit and a purification unit.
[0078] The electricity generated by photovoltaic power generation can be transmitted to the hydrogen production unit through the photovoltaic grid-connected inverter, the wind power can be transmitted to the hydrogen production unit through the wind power converter, and the electricity from the power grid can be directly transmitted to the hydrogen production unit.
[0079] Each hydrogen production unit in this embodiment is controlled by a controller, and the controller can control the start and stop of the hydrogen production unit and the size of the hydrogen production power. In this embodiment, a fluctuating new energy power generation system such as wind energy and photovoltaic power is used for power supply.
[0080] Reference Figure 2 , the operating state control method of the hydrogen production unit may include:
[0081] S11. Acquire power generation parameters of the new energy power generation system and equipment parameters of the hydrogen production unit in the hydrogen production system.
[0082] In this embodiment, the power generation parameter of the new energy power generation system may be the real-time power generation power P of the new energy power generation system. N And the power fluctuation threshold ΔP max , power fluctuation threshold ΔP max It can be the maximum value of power fluctuation.
[0083] The power fluctuation threshold may be the maximum value of the power change within a preset time period from the current cycle. Specifically, the power fluctuation threshold ΔP of the new energy power generation system is determined according to the characteristics of the new energy system, such as light intensity, wind speed, time and other factors. max If the photovoltaic system has sunlight in the time period of 8:00-18:00, the power change every 5 minutes in the past day is taken as the basic data, the maximum power change is screened out, and used as the power fluctuation threshold ΔP max In addition, the power fluctuation threshold for a period of time in the future can be predicted by forecasting.
[0084] It should be noted that the power generation parameters in this embodiment may include the power generation power P N And the power fluctuation threshold ΔP max In addition, it can also be the power generation current and the current fluctuation threshold, or the power generation voltage and the voltage fluctuation threshold. In this embodiment, the power generation parameter is the above-mentioned power generation power P N And the power fluctuation threshold ΔP max The same is true when the power generation parameters are the power generation current and the current fluctuation threshold, or the power generation voltage and the voltage fluctuation threshold.
[0085] In this embodiment, the equipment parameters of the hydrogen production unit in the hydrogen production system include:
[0086] The total number of hydrogen production units in the hydrogen production system is I. If there are 5 hydrogen production units in the hydrogen production system, the total number I is 5.
[0087] The power range of the hydrogen production unit [P H_min ,P H_max ]; The interval boundary of the power range is the minimum power value P H_min And the maximum power P H_max Among them, the minimum power P H_min And the maximum power P H_max is the minimum power of a single hydrogen production unit P H_min And the maximum power P H_max .
[0088] From the above, the power generation parameters of the new energy power generation system and the equipment parameters of the hydrogen production unit in the hydrogen production system are obtained, including:
[0089] Obtain the power generation power and power fluctuation threshold of the new energy power generation system;
[0090] The total number of hydrogen production units in the hydrogen production system and the power range of the hydrogen production units are obtained; the boundaries of the power range are the minimum power value and the maximum power value.
[0091] S12. Determine the target number and hydrogen production parameters of the hydrogen production units that should be in operation in the hydrogen production system in the current cycle, corresponding to the power generation parameters and the equipment parameters.
[0092] In this embodiment, the hydrogen production parameter includes the hydrogen production power. The target number refers to the number of hydrogen production units that should produce hydrogen in the current cycle.
[0093] It should be noted that it is necessary to determine the power generation parameters P of the new energy power generation system. N Is it greater than the minimum power value P of the hydrogen production unit? H_min If it is greater than, execute step S12. If it is not greater than, it means that the power generation parameters of the current new energy power generation system cannot meet the minimum power requirement of a hydrogen production unit. At this time, continue to judge until it is greater than, execute step S12.
[0094] In this embodiment, the operation state control method of the hydrogen production unit in the embodiment of the present invention is executed according to a cycle, and the cycle may be 10 minutes or other values to avoid frequent start and stop of the hydrogen production unit.
[0095] S13, obtaining the status of the hydrogen production unit in the hydrogen production system in the previous cycle.
[0096] In this embodiment, the state includes a state identifier and a duration corresponding to the state identifier; the state identifier includes an operating state or a non-operating state; the operating state includes a stable hydrogen production state or a fluctuating hydrogen production state.
[0097] The non-operating state means that the hydrogen production unit is not working, and may be in a standby state or a shutdown state.
[0098] The operating status can also be divided into two types. One is the stable hydrogen production state. In the stable hydrogen production state, the hydrogen production power of the hydrogen production unit is fixed.
[0099] The other is the fluctuating hydrogen production state. In the fluctuating hydrogen production state, the hydrogen production power of the hydrogen production unit fluctuates according to the power fluctuation trend of the new energy power generation system.
[0100] In this embodiment, in addition to recording the above-mentioned state identifiers, the duration of each state is also recorded.
[0101] In this embodiment, the total number of hydrogen production units is represented by I, the number of hydrogen production units in operation is represented by i, the number of hydrogen production units in a stable hydrogen production state is represented by i1, and the number of hydrogen production units in a fluctuating hydrogen production state is represented by i2.

[0103] Among them, when the hydrogen production unit is running, the parameter t of the hydrogen production unit 3i Clear, when the hydrogen production unit is not running, the parameter t of the hydrogen production unit 1i ,t 2i That is to say, a hydrogen production unit has three time attributes. When the hydrogen production unit works in one state, the corresponding time attribute starts timing, and the other two time attributes are reset.
[0104] S14. Adjust the status of the hydrogen production units in the hydrogen production system in the current cycle according to the status of the hydrogen production units in the hydrogen production system in the previous cycle and the target number of hydrogen production units that should be in operation in the current cycle.
[0105] In this embodiment, the state of the hydrogen production unit that was in the operating state in the previous cycle can be adjusted to the non-operating state, or the working state of the hydrogen production unit that was in the non-operating state in the previous cycle can be adjusted to the operating state. In addition, the hydrogen production unit can be adjusted from a stable hydrogen production state to a fluctuating hydrogen production state, or the hydrogen production unit can be adjusted from a fluctuating hydrogen production state to a stable hydrogen production state.
[0106] In this embodiment, the target number and hydrogen production parameters of the hydrogen production units that should be in operation in the hydrogen production system in the current cycle can be determined, corresponding to the power generation parameters of the new energy power generation system and the equipment parameters of the hydrogen production units in the hydrogen production system. When adjusting the state of the hydrogen production units in the hydrogen production system in the current cycle, in addition to considering the target number and hydrogen production parameters of the hydrogen production units that should be in operation in the current cycle, the state of the hydrogen production units in the hydrogen production system in the previous cycle will also be considered, that is, the state of the current cycle is determined from both the external situation and the internal situation of the hydrogen production unit, thereby avoiding the method of directly controlling the start and stop of the hydrogen production unit and the size of the hydrogen production power in real time according to the power generation parameters of the new energy power generation system, resulting in large changes in the hydrogen production power of the hydrogen production unit and frequent start and stop of the hydrogen production unit, thereby reducing the life of the hydrogen production unit and the hydrogen production efficiency.
[0107] In another implementation of the present invention, referring to Figure 3 , step S12 may include:
[0108] S21. Calculate the minimum number of hydrogen production units according to the generated power and the maximum power, and calculate the maximum number of hydrogen production units according to the generated power and the minimum power.
[0109] In this embodiment, the minimum number of hydrogen production units is i min express.
[0110]
[0111] Among them, P N is the power generation of the new energy power generation system, P H_max is the maximum power value mentioned above.
[0112] The maximum number of hydrogen production units is i max express.
[0113]
[0114] Among them, P H_min is the minimum power mentioned above.
[0115] In this embodiment, i can be determined once in each execution cycle. min and i max The execution cycle can be set to 10 minutes or other values to avoid frequent start and stop of the hydrogen production unit.
[0116] S22. Calculate a number compensation value according to the power fluctuation threshold and the maximum power value.
[0117] In this embodiment, in order to ensure that there is a surplus of hydrogen production units, a number of hydrogen production units equal to the number compensation value may be set to be added to the hydrogen production work.
[0118] In this embodiment, the number compensation value is represented by Δi.
[0119]
[0120] Among them, ΔP max Indicates the power fluctuation threshold, P H_max is the maximum power value mentioned above.
[0121] S23, calculating the minimum number of hydrogen production units and the sum of the number compensation values, and using the sum as the target number of hydrogen production units that should be in operation in the hydrogen production system.
[0122] In this embodiment, the target number is represented by i. Where i=i min +Δi.
[0123] In actual applications, the calculated target number i may exceed the total number I of hydrogen production units in the hydrogen production system, resulting in the determined target number being unable to be used normally. Therefore, in this embodiment, after the minimum number of hydrogen production units and the sum of the number compensation value are calculated, the sum is verified.
[0124] Specifically, step S23 may include:
[0125] 1) Calculate the minimum number of hydrogen production units and the sum of the number compensation value, and use it as the initial number of hydrogen production units that should be in operation in the hydrogen production system.
[0126] 2) Determine whether the initial quantity is within a preset range.
[0127] The preset interval range is an interval range constructed by the maximum number of hydrogen production units, the total number of hydrogen production units, and the minimum number of hydrogen production units.
[0128] In this embodiment, it should be ensured that the number i of hydrogen production units in operation satisfies:
[0129] i∈[i min ,min(I,i max )],in
[0130] 3) If so, the initial number is determined as the target number of hydrogen production units that should be in operation in the hydrogen production system.
[0131] If it is within the above range, the initial quantity is used as the target quantity.
[0132] If i is less than i min , then i takes the value i min. If i is greater than min(I,i max ), then i takes the value min(I,i max ).
[0133] S24, determining hydrogen production parameters of the hydrogen production units that should be in operation in the hydrogen production system in the current cycle.
[0134] In this embodiment, the hydrogen production parameters include hydrogen production power. In this embodiment, a power average distribution method can be adopted to evenly distribute the power generated by the new energy system to each hydrogen production unit in operation. The power P of each hydrogen production unit is H for

[0136] Among them, P N is the power generation power of the new energy power generation system, i is the target number mentioned above, that is, the ratio of the power generation power to the target number is used as the hydrogen production power of the hydrogen production unit that should be in operation in the hydrogen production system in the current cycle.
[0137] This method is a simple power allocation method. If the purpose is to further reduce the power variation range, the optimal allocation method can be used to divide the hydrogen production units in operation into the above-mentioned stable hydrogen production state and fluctuating hydrogen production state, and determine the hydrogen production power of each state respectively.

[0139] S31. Calculate the first number of hydrogen production units that should be in a stable hydrogen production state in the current cycle and the second number of hydrogen production units that should be in a fluctuating hydrogen production state in the current cycle according to the target number, the number compensation value and the specified multiple.
[0140] In this embodiment, the specified multiple may be a value between 1.5 and 2. When the calculated first number and the second number are not positive integers, the first number and the second number may be determined by rounding.
[0141] The value of the first number i1 of the hydrogen production units that should be in a stable hydrogen production state in the current cycle is the target number i-the number compensation value Δi*the specified multiple.

[0143] S32. Calculate the hydrogen production power of the hydrogen production unit that should be in a stable hydrogen production state in the current cycle according to the generated power, the power fluctuation threshold and the first number.
[0144] Specifically, the hydrogen production power of the first number i1 hydrogen production unit is P H_con1 ,
[0145] Among them, P N is the power generation of the new energy power generation system, ΔP max Indicates the power fluctuation threshold.
[0146] S33. Calculate the hydrogen production power of the hydrogen production unit that should be in the fluctuating hydrogen production state in the current cycle based on the power generation power, the second number, the hydrogen production power of the hydrogen production unit that should be in the stable hydrogen production state in the current cycle, and the first number.
[0147] Specifically, the second number, the hydrogen production power of the i2 hydrogen production units, is P H_con2 It is expressed as:
[0148]
[0149] Among them, P N is the power generation of the new energy power generation system, P H_con1 is the hydrogen production power of i1 hydrogen production unit.
[0150] In this embodiment, after determining the power generation parameters and the equipment parameters, the target number and hydrogen production parameters of the hydrogen production units that should be in operation in the hydrogen production system in the current cycle can be determined through the method steps in this embodiment, so as to control the working state of the current hydrogen production unit and avoid frequent starting and stopping.
[0151] In another implementation of the present invention, referring to Figure 5 Step S14 "adjusting the state of the hydrogen production unit in the hydrogen production system in the current cycle according to the state of the hydrogen production unit in the hydrogen production system in the previous cycle and the target number of hydrogen production units that should be in operation in the current cycle" may include:
[0152] S41. Determine whether the target quantity is greater than the first historical quantity; if so, execute step S42; if not, execute step S43.
[0153] Specifically, it is determined whether the target number in the current cycle is greater than the first historical number of hydrogen production units in operation in the hydrogen production system in the previous cycle.
[0154] In this embodiment, the first historical number refers to the number of hydrogen production units in operation in the hydrogen production system in the previous period.
[0155] It is necessary to determine whether the target quantity of the current cycle is greater than the first historical quantity, that is, to determine whether the number of hydrogen production units required to produce hydrogen in the current cycle is greater than the number in the previous cycle.
[0156] S42. Select first target hydrogen production units that are not in operation in the current cycle and whose number is a first difference from the hydrogen production system, and adjust the state of the first target hydrogen production units to a fluctuating hydrogen production state.
[0157] The first difference is the absolute difference between the target quantity and the first historical quantity.
[0158] When the target quantity is greater than the first historical quantity, it indicates that a new hydrogen production unit is needed to produce hydrogen. At this time, a first difference is calculated, which is the absolute difference between the target quantity and the first historical quantity.
[0159] Then, the first target hydrogen production units having a number equal to the first difference are selected from the hydrogen production units that are not in operation. In this embodiment, the first target hydrogen production units can be selected randomly or in ascending order of serial numbers.
[0160] Then, the working state of the first target hydrogen production unit is controlled to be adjusted to a fluctuating hydrogen production state, and the hydrogen production power is calculated according to the method in the above embodiment.
[0161] S43, selecting fourth target hydrogen production units whose number is the first difference from the hydrogen production system in descending order of the operation time in the operation state, and adjusting the state of the fourth target hydrogen production units to a non-operating state.
[0162] When the target quantity is not greater than the first historical quantity, it indicates that the number of hydrogen production units needs to be reduced.
[0163] At this time, when reducing the number of hydrogen production units, the hydrogen production units with longer operating time can be shut down, and the operating time in the operating state can be the above t 1i or 2i That is, no matter it is a stable hydrogen production state or a fluctuating hydrogen production state, it is calculated as the operating time in the operating state.
[0164] In this embodiment, fourth target hydrogen production units having a first difference value are selected from the hydrogen production system in descending order of the operation time in the operation state. The first difference value in this embodiment is the same as the first difference value described above.
[0165] Then, the working state of the fourth target hydrogen production unit is adjusted to a non-operating state, that is, the fourth target hydrogen production unit is controlled to stop working.
[0166] S44, determine whether the first number is greater than the second historical number; if so, execute step S45; if not, execute step S46.
[0167] Specifically, it is determined whether the first number of the current cycle is greater than the second historical number of hydrogen production units in the hydrogen production system in the previous cycle that are in a stable hydrogen production state.
[0168] The first number is the number of hydrogen production units that should be in a stable hydrogen production state in the current cycle. The second historical number refers to the number of hydrogen production units in the hydrogen production system that were in a stable hydrogen production state in the previous cycle.
[0169] That is, in this embodiment, it is determined whether the number of cells in the stable hydrogen production state required in the current cycle is greater than the number of cells in the stable hydrogen production state in the previous cycle.
[0170] S45. Select second target hydrogen production units whose number is the second difference according to the order of the operation time of the hydrogen production units in the fluctuating hydrogen production state from large to small, and adjust the state of the second target hydrogen production units to the stable hydrogen production state.
[0171] The second difference is the absolute difference between the first number and the second historical number.
[0172] That is to say, in this embodiment, when the number of hydrogen production units required to be in a stable hydrogen production state in the current cycle is greater than the number of hydrogen production units in a stable hydrogen production state in the previous cycle, the working state of the hydrogen production units in the fluctuating hydrogen production state is controlled to be adjusted to a stable hydrogen production state.
[0173] In this embodiment, when screening the hydrogen production units in the fluctuating hydrogen production state, the order of the operating time in the fluctuating hydrogen production state can be descending, that is, according to t 2i The hydrogen production units with the second difference are selected in order from large to small and used as the second target hydrogen production units. Then, the working state of the second target hydrogen production unit is adjusted to a stable hydrogen production state.
[0174] S46. Filter out third target hydrogen production units whose number is the second difference in order of the operation time in a stable hydrogen production state from small to large.
[0175] S47, adjusting the working state of the third target hydrogen production unit to a fluctuating hydrogen production state.
[0176] The second difference is the absolute difference between the first number and the second historical number.
[0177] In this embodiment, when the number of hydrogen production units required to be in a stable hydrogen production state in the current cycle is smaller than the number of hydrogen production units in a stable hydrogen production state in the previous cycle, it is necessary to control some hydrogen production units in a stable hydrogen production state to exit the stable hydrogen production state and adjust to a fluctuating hydrogen production state.
[0178] When screening hydrogen production units in a stable hydrogen production state, the order of operation time in a stable hydrogen production state from small to large is used, that is, according to t 1i In order from small to large, the third target hydrogen production units having a quantity equal to the second difference value are screened out.
[0179] In this embodiment, the factors affecting the life and efficiency of the hydrogen production equipment are taken into consideration, and the operation cycle of the hydrogen production unit is reasonably allocated to avoid the situation where some hydrogen production units work for a long time and cause equipment loss, and some hydrogen production units do not work for a long time and cause low equipment utilization. In this way, the operation cycle of the hydrogen production unit is reasonably arranged, the life cycle of each hydrogen production unit is balanced, the life and efficiency of the entire hydrogen production system are improved, and the frequent start and stop of the hydrogen production unit is avoided.
[0180] S48. Swap the states of the first target hydrogen production unit to be adjusted, whose operating time is greater than a preset operating time threshold, with the second target hydrogen production unit to be adjusted, whose number is the same as the first target hydrogen production unit to be adjusted and which is not in the operating state.
[0181] In this embodiment, in order to avoid the problem of long operating time of some hydrogen production units resulting in large losses, a preset operating time threshold can be set in this embodiment, such as half an hour. When the operating time in the operating state is greater than the preset operating time threshold, the state of the second target hydrogen production unit to be adjusted is swapped with the second target hydrogen production unit to be adjusted, which is arranged in descending order of the time not in the operating state and has the same number as the first target hydrogen production unit to be adjusted whose operating time in the operating state is greater than the preset operating time threshold.
[0182] For example, if there are five first target hydrogen production units to be adjusted whose operating time in the operating state is greater than the preset operating time threshold, then five second target hydrogen production units to be adjusted are selected in descending order of the time they are not in the operating state, and the states of the first target hydrogen production units to be adjusted and the second target hydrogen production units to be adjusted are swapped.
