Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The hydrogen production control method provided by the application is used for controlling the hydrogen production process of a hydrogen production system comprising a plurality of hydrogen production power supplies, and adjusting the predicted hydrogen production power and the hydrogen production duration output by each hydrogen production power supply in the hydrogen production process so as to ensure that the hydrogen production amount in a certain time meets the actual application requirements. The hydrogen production control method provided by the application can be applied to electronic equipment capable of executing a preset control program and performing corresponding data processing functions, wherein the electronic equipment can be a computer, a palm computer or a data processing server, and can be applied to a server implementation at a network side in certain cases. Referring to fig. 1, fig. 1 is a flowchart of a hydrogen production control method provided in an embodiment of the present application, where the flow of the hydrogen production control method provided in the embodiment may include:
s100, obtaining hydrogen production predicted power of each hydrogen production power supply in each hydrogen production time period.
As mentioned above, the hydrogen production power source of the hydrogen production system in the existing application mainly includes a new energy power generation system, an energy storage system and an ac power grid, where the new energy power generation system includes a wind power generation system and a photovoltaic power generation system, and of course, other types of hydrogen production power sources are also possible, which are not listed here. In consideration of the obvious periodicity of the power supply process of the photovoltaic power generation system, that is, the hydrogen production power can be output only in the daytime, in the hydrogen production control method provided in this embodiment and the subsequent embodiments, the hydrogen production process is controlled with one natural day as a period, and the natural day for controlling the hydrogen production process is defined as the hydrogen production day.
Further, considering that the hydrogen demand of users is different in different time periods in practical application, taking a hydrogen station of a bus as an example, a large amount of hydrogen is generally required in three time periods of morning, noon and evening, and the hydrogen demand of the rest time periods is obviously lower than that of the three time periods, so that the hydrogen supply in the time period with the large hydrogen demand is required to be preferentially ensured in practical application. Based on the above, in practical application, the hydrogen demand of different time periods of the hydrogen production day can be predicted according to the hydrogen demand prediction data, the hydrogen production day is divided into different hydrogen production time intervals based on the prediction result, any hydrogen production time interval is taken as a target hydrogen production time interval, and the hydrogen production process is controlled according to the target hydrogen production time interval. The hydrogen production time period described in this embodiment is further divided from the target hydrogen production time period.
Based on the foregoing, each hydrogen production period described in this embodiment belongs to the same target hydrogen production period, and thus is continuous in time, not discrete.
Optionally, for any hydrogen production power source, the output power of the hydrogen production power source in the hydrogen production day can be predicted, meanwhile, the hydrogen production device in the hydrogen production system has a certain rated hydrogen production power, the hydrogen production power input by the hydrogen production device cannot be larger than the rated hydrogen production power of the hydrogen production device, and therefore, the part of the output power of the hydrogen production power source, which is larger than the rated hydrogen production power of the hydrogen production device, cannot be used for hydrogen production, so that after the predicted power of the hydrogen production power source in the hydrogen production time period and the rated hydrogen production predicted power of the hydrogen production device are obtained, the smaller value of the predicted power of the hydrogen production power source and the rated hydrogen production predicted power of the hydrogen production device is required to be used as the available hydrogen production predicted power of the hydrogen production power source in the hydrogen production time period.
Alternatively, referring to fig. 2, fig. 2 is a schematic diagram of the relationship between the output power curves of the hydrogen generation power supplies and the available hydrogen generation predicted power curves according to the embodiment of the present application, it can be seen from fig. 2 that the output powers of the hydrogen generation power supplies have different variation characteristics, meanwhile, fig. 2 also shows the power curves when the wind power generation system and the photovoltaic power generation system are commonly used for hydrogen generation, which can be understood as the power curves of the new energy power generation system and the power curves when the ac power grid and the energy storage system are commonly used for hydrogen generation, where, in the power curves corresponding to the new energy power generation system, pmax corresponds to the maximum hydrogen generation power of the hydrogen generation device, pmin is the minimum hydrogen generation power of the hydrogen generation device, no matter how the hydrogen generation power supplies are allocated, the total hydrogen generation power is in the power ranges corresponding to Pmin and Pmax, and the curves based on the available hydrogen generation power obtained on the premise are shown as the right-hand curves in fig. 2.
The power curves shown in fig. 2 are schematic diagrams, and the performance of the hydrogen production power supply is specific in practical application.
In order to adjust the hydrogen production power of various hydrogen production power sources in the target hydrogen production time interval, specifically to each hydrogen production time period, the embodiment sets corresponding energy supply proportion for various hydrogen production power sources, so that in the step, under the condition that the available hydrogen production predicted power of each hydrogen production power source is determined, the available hydrogen production predicted power of each hydrogen production power source in each hydrogen production time period is obtained, the energy supply proportion of each hydrogen production power source in each hydrogen production time period can also be understood as the energy supply proportion of each hydrogen production power source is obtained, and after the energy supply proportion of each hydrogen production power source and the available hydrogen production predicted power in each hydrogen production time period are obtained, the product of the energy supply proportion and the available hydrogen production predicted power in each hydrogen production time period is calculated, and the hydrogen production predicted power of each hydrogen production power source in each hydrogen production time period is obtained. It is conceivable that the power supply ratio of each hydrogen production power source may use a preset initial value when the present control method is first executed on any hydrogen production day.
The above-mentioned processes of predicting the output power of various hydrogen production power sources, predicting the hydrogen demand of the hydrogen production system, and the like may be implemented based on the prior art, and the present application is not limited thereto.
S110, adjusting hydrogen production time length of each hydrogen production power supply operated with corresponding hydrogen production predicted power to obtain a plurality of hydrogen production schemes.
As described above, the target hydrogen production time interval described in this embodiment is obtained by dividing the hydrogen production day, and further, any hydrogen production time period is obtained by dividing the target hydrogen production time interval, so it can be seen that the hydrogen production time period in any hydrogen production time period of any hydrogen production power source is longest, that is, the time period corresponding to the hydrogen production time period, so when the hydrogen production time periods of each hydrogen production power source operating with the corresponding predicted hydrogen production power are adjusted, the adjustment should be performed within the time period range of the hydrogen production time period, and each adjustment obtains a hydrogen production scheme for operating with the corresponding predicted hydrogen production power for the corresponding hydrogen production time period, and all possible hydrogen production time periods are traversed, so as to obtain multiple hydrogen production schemes.
Optionally, in the process of adjusting the hydrogen production duration, in order to reduce the calculation amount and improve the program execution efficiency, the hydrogen production duration may be adjusted according to a certain step, for example, the step is 10 minutes. Furthermore, the hydrogen production time periods can be equal in duration or different in duration, and in order to simplify the adjustment process, the target hydrogen production time intervals can be equally divided to obtain the hydrogen production time periods with equal duration. Of course, the hydrogen production day may be defined as a reference, and the hydrogen production day may be divided into a plurality of hydrogen production time periods first, and then the number of hydrogen production time periods included in the hydrogen production time period may be determined according to a specific range of the hydrogen production time period.
In summary, this step ultimately results in a plurality of hydrogen production schemes operating for different hydrogen production durations with corresponding predicted hydrogen production power outputs.
S120, respectively calculating the hydrogen output of each hydrogen production scheme according to the hydrogen production predicted power and the hydrogen production duration corresponding to each hydrogen production power supply in each hydrogen production scheme.
After the hydrogen production schemes are obtained through the steps, the hydrogen output of each hydrogen production scheme can be calculated according to the hydrogen production predicted power and the hydrogen production duration corresponding to each hydrogen production power supply in each hydrogen production scheme. According to the prior art, the hydrogen production device absorbs electric energy and generates hydrogen based on the electric energy, and energy loss inevitably exists in the hydrogen production process, namely, the hydrogen production system corresponds to certain energy conversion efficiency in the hydrogen production process, and the energy conversion efficiency is determined for the determined hydrogen production device.
S130, judging whether a target hydrogen production scheme with the hydrogen output in a preset hydrogen production range exists, if not, executing S140, and if so, executing S150.
As described above, the hydrogen production control method provided in this embodiment is to ensure that the hydrogen production amount meets the application requirement, so after the hydrogen production amount of each hydrogen production scheme is obtained, it is determined whether there is a hydrogen production scheme whose hydrogen production amount is within the preset hydrogen production range, as the target hydrogen production scheme, if there is, S150 is executed, and if there is no hydrogen production scheme, S140 is executed.
It is conceivable that if the hydrogen production schedule in which the hydrogen production amount is within the preset hydrogen production range includes a plurality of hydrogen production schedules, the hydrogen production schedule in which the hydrogen production amount is the largest should be selected as the target hydrogen production schedule.
S140, adjusting hydrogen production predicted power of each hydrogen production power supply.
As described above, the predicted power of each hydrogen generation power supply in the hydrogen generation day is determined, and the power of each hydrogen generation power supply for hydrogen generation is adjusted by adjusting the energy supply ratio in the present step, therefore, in the present step, the predicted power of each hydrogen generation power supply is adjusted by adjusting the energy supply ratio of each hydrogen generation power supply, and after the adjustment of the predicted power of hydrogen generation is completed, the process returns to S100.
It is conceivable that, after returning, S100 obtains the hydrogen production predicted power adjusted by each hydrogen production power source.
S150, controlling the hydrogen production system to produce hydrogen according to the target hydrogen production scheme.
If a target hydrogen production scheme with the hydrogen output in a preset hydrogen production range exists, the corresponding hydrogen production power sources can be controlled to supply power to the hydrogen production device according to the hydrogen production power and the hydrogen production duration of each hydrogen production power source in the target hydrogen production scheme to generate hydrogen.
In summary, according to the hydrogen production control method provided by the application, the hydrogen production predicted power and the hydrogen production time length of each hydrogen production power supply are adjusted to obtain a plurality of hydrogen production schemes, so that the hydrogen production schemes meeting the preset hydrogen production requirements control the operation of the hydrogen production system, the hydrogen production of the hydrogen production system is effectively ensured to meet the expected requirements, and the problems in the prior art are solved.
Based on the implementation process of the hydrogen production control method provided by the embodiment, it can be seen that even if the hydrogen production duration is adjusted according to the determined hydrogen production power, the obtained hydrogen production schemes are very numerous, and accordingly, calculating the hydrogen output of all the hydrogen production schemes consumes a great deal of time, so that the control efficiency is seriously affected, and a great deal of hardware resources are occupied. To solve this problem, the embodiment provides another hydrogen production control method based on the embodiment shown in fig. 1, and the specific flow of this method may be shown in fig. 3. It should be noted that, only the portion of the present embodiment that is different from the embodiment shown in fig. 1 will be expanded, and the rest of the present embodiment can be seen from the foregoing, which will not be repeated here.
Specifically, when hydrogen production time length of each hydrogen production power supply operated with corresponding hydrogen production power is adjusted, a plurality of hydrogen production schemes are obtained, and the following steps are executed:
s1201, hydrogen production contribution values of all hydrogen production schemes are calculated respectively.
It should be noted that, in this embodiment, the hydrogen production contribution value is used to characterize the economy of the hydrogen production scheme, and the higher the hydrogen production contribution value, the lower the hydrogen production cost required in the case of producing the same hydrogen, or the higher the hydrogen production contribution value, the greater the amount of the obtained hydrogen at the same hydrogen production cost.
Optionally, in order to accurately calculate the hydrogen production contribution value of each hydrogen production scheme, the preset weight coefficient is set for each hydrogen production power supply in each hydrogen production time period in this embodiment. In this embodiment, the weight coefficient of the hydrogen production power source is mainly equal to the energy capacity of the hydrogen production power source, such as the installed capacity of the photovoltaic power generation system and the wind power generation system, the energy storage capacity of the energy storage system, and besides the energy capacity, the power unit price of the hydrogen production power source, the availability convenience of the hydrogen production power source, and other conditions, and in practical application, the weight coefficient of the hydrogen production power source can be set according to the specific situation of the hydrogen production power source. It should be emphasized that the preset weight coefficient mentioned in this embodiment is inversely related to the hydrogen production cost of the hydrogen production power supply in the corresponding hydrogen production period, that is, the higher the hydrogen production cost is, the smaller the corresponding preset weight coefficient is.
It is conceivable that the preset weight coefficients of the wind power generation system, the photovoltaic power generation system and the energy storage system are often fixed for a certain hydrogen production system, and the preset weight coefficients of the ac power grid are different in different hydrogen production time periods due to the fact that the power prices of the ac power grid are changed in different time periods.
Based on the above premise, the calculation process of the hydrogen production contribution value is described below by way of a specific example:

Correspondingly, the hydrogen production power vector of the available energy storage system isHydrogen production power vector of wind power generation system is +.>The hydrogen production power vector of the photovoltaic power generation system is
Under the condition that N hydrogen production time periods are equal in length, the hydrogen production time length of the alternating current power grid, the energy storage system, the wind power generation system and the photovoltaic power generation power grid in any one hydrogen production time period can be expressed as T 1j 、T 2j 、T 3j 、T 4j The foregoing process of adjusting the hydrogen production duration should be performed within a duration range corresponding to the hydrogen production time period, that is, the following rule is satisfied:
wherein j represents a jth hydrogen production period;
T Z indicating the duration of the target hydrogen production time interval.
The matrix QT is used for representing the hydrogen production contribution value of the hydrogen production scheme, and the following calculation formula is provided:
in the above formula, k ij I is 1, i is 2, i is 3, i is 4, i is a preset weight coefficient of the alternating current power grid in the jth hydrogen production time period, i is 2, i is 3, i is 4, i is a preset weight coefficient of the energy storage system in each hydrogen production time periodThe power generation system presets weight coefficients in each hydrogen production time period; wherein P is ij I values 1, 2, 3, 4 of the above-mentioned four hydrogen production power sources, respectively, in the jth hydrogen production time zone.
The matrix is further calculated, and then:
based on the above formula, when calculating the hydrogen production contribution value of the hydrogen production scheme, the hydrogen production contribution value of the hydrogen production scheme in each hydrogen production time period can be calculated respectively, that is, the hydrogen production contribution value is calculated according to the preset weight coefficient, the hydrogen production predicted power and the hydrogen production duration of each hydrogen production power source in any hydrogen production time period, specifically, the product of the preset weight coefficient, the hydrogen production predicted power and the hydrogen production duration of each hydrogen production time period of the hydrogen production power source is calculated to obtain a corresponding first calculation result, and the above formula is exemplified by k 11 P 11 T 11 Namely one of the first calculation results is calculated, and then the sum of the first calculation results corresponding to the same hydrogen production time period is calculated, so as to obtain the hydrogen production contribution sub-value of the hydrogen production scheme in the corresponding hydrogen production time period, and the above formula is taken as an example 11 P 11 T 11 +k 2 P 21 T 21 +k 3 P 31 T 31 +k 4 P 41 T 41 The result is that the hydrogen production contribution sub-value of each hydrogen production power supply in the first hydrogen production time period is further obtained, and the sum of the hydrogen production contribution sub-values of each hydrogen production power supply in each hydrogen production time period is further obtained, so that the hydrogen production contribution value of the scheme is obtained, and the method can be specifically expressed as follows:
qt＝k 11 P 11 T 11 +k 2 P 21 T 21 +k 3 P 31 T 31 +k 4 P 41 T 41 +k 12 P 12 T 12 +k 2 P 22 T 22 +
k 3 P 32 T 32 +k 4 P 42 T 42 +L+k 1N P 1N T 1N +k 2 P 2N T 2N +k 3 P 3N T 3N +k 4 P 4N T 4N
and executing the calculation process aiming at each hydrogen production scheme to obtain the hydrogen production contribution value corresponding to each hydrogen production scheme.
S1202, judging whether at least one candidate hydrogen production scheme with the hydrogen production contribution value larger than a preset threshold exists in the hydrogen production schemes, if not, executing S1203, and if so, executing S1204.
In the obtained hydrogen production schemes, the hydrogen production schemes are screened according to the size relation that the hydrogen production contribution value corresponding to the hydrogen production scheme is smaller than a preset threshold value, if the hydrogen production contribution value of the hydrogen production scheme is larger than the preset threshold value, the hydrogen production scheme is reserved as a candidate hydrogen production scheme, and conversely, if the hydrogen production contribution value of the hydrogen production scheme is smaller than or equal to the preset threshold value, the hydrogen production scheme is not needed. Based on this, if the hydrogen production contribution value of each hydrogen production scheme is equal to or less than the preset threshold, S1203 is executed, and if there is at least one candidate hydrogen production scheme whose hydrogen production contribution value is greater than the preset threshold, S1204 is executed.
It should be noted that, for the preset threshold, specific control precision and actual application requirement setting can be combined, and the specific setting of the preset threshold is not limited by the present application.
S1203, adjusting hydrogen production predicted power of each hydrogen production power supply.
Alternatively, the execution of S1203 may be implemented with reference to S140 in the embodiment shown in fig. 1, which will not be repeated here, and returns to S100 after the adjustment of the predicted power for hydrogen production is completed.
S1204, taking the candidate hydrogen production scheme with the largest hydrogen production contribution value in the candidate hydrogen production schemes as a target hydrogen production scheme.
If a plurality of candidate hydrogen production schemes exist, the candidate hydrogen production scheme with the largest hydrogen production contribution value in the candidate hydrogen production schemes is selected as a target hydrogen production scheme in order to obtain better hydrogen production yield.
S1205, calculating the hydrogen output of the target hydrogen production scheme.
As described above, the hydrogen production device corresponds to the preset conversion efficiency in the hydrogen production process, and after determining the target hydrogen production scheme, the hydrogen production power supply amount of the target hydrogen production scheme may be calculated first, specifically, may be calculated according to the following formula:
Q＝P 11 T 11 +P 21 T 21 +P 31 T 31 +P 41 T 41 +L+P 1N T 1N +P 2N T 2N +P 3N T 3N +P 4N T 4N
after the total hydrogen production electric quantity is obtained, calculating the product of the preset conversion efficiency and the total hydrogen production electric quantity to obtain the hydrogen output of the target hydrogen production scheme. Specifically, the method can be calculated by referring to the following formula:
Hq＝δ(P 11 T 11 +P 21 T 21 +P 31 T 31 +P 41 T 41 +L+P 1N T 1N +P 2N T 2N +P 3N T 3N +P 4N T 4N )
it is conceivable that after the hydrogen output of the target hydrogen production scheme is obtained, the step S130 directly judges whether the hydrogen output of the target hydrogen production scheme is within the preset hydrogen production range, and the other schemes do not need to perform calculation of the hydrogen output and subsequent steps, so that the calculated amount can be effectively reduced, and the control efficiency is improved. For the execution of the remaining steps, reference may be made to the embodiment shown in fig. 1, and details thereof are not repeated here.
According to practical operation experience and a power generation principle, the power generation process of the wind power generation system and the photovoltaic power generation system has obvious fluctuation, and in order to fully utilize the electric energy output by the wind power generation system and the photovoltaic power generation system, the electric energy of the wind power generation system and the photovoltaic power generation system should be preferentially used in the hydrogen production process, and when the electric energy output by the wind power generation system and the photovoltaic power generation system is difficult to meet the hydrogen production requirement, the energy storage system and the alternating current power grid are considered.

Meanwhile, the energy storage system is controlled to be in a charging mode, and it is conceivable that the energy storage system can play a role of a buffer pool with more charging and less supplementing in the whole hydrogen production system, the output power of the photovoltaic power generation system and the wind power generation system at least can meet the hydrogen production requirement, and if the output power of the photovoltaic power generation system and the wind power generation system are still remained, the output power of the photovoltaic power generation system and the wind power generation system can be stored in the energy storage system, so that the energy storage system is controlled to be in the charging mode in the step, which is just a description of the running state of the energy storage system, and is not a description of continuous charging of the energy storage system, and the specific charging process is also determined by combining the magnitude relation between the output power of the photovoltaic power generation system and the wind power generation system and the rated hydrogen production power of the hydrogen production device.
