Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The hydrogen production control method provided by the invention is used for controlling the hydrogen production process of the hydrogen production system comprising a plurality of hydrogen production power supplies and adjusting the predicted hydrogen production power and the hydrogen production time output by each hydrogen production power supply in the hydrogen production process so as to ensure that the hydrogen output in a certain time meets the actual application requirements. The hydrogen production control method provided by the invention can be applied to electronic equipment which can execute a preset control program and perform a corresponding data processing function, the electronic equipment can be a computer, a palm computer or a data processing server, and certainly, under certain conditions, the hydrogen production control method can also be applied to a server on a network side for realization. Referring to fig. 1, fig. 1 is a flow chart of a hydrogen production control method according to an embodiment of the present invention, where the flow chart of the hydrogen production control method according to the embodiment may include:
s100, obtaining hydrogen production predicted power of each hydrogen production power source in each hydrogen production time period.
As mentioned above, the hydrogen production power supply 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, wherein 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 supplies may be included, which are not listed here. In consideration of the fact that the power supply process of the photovoltaic power generation system has obvious periodicity, that is, 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 by taking one natural day as a period, and the natural day on which the hydrogen production process is controlled is defined as a hydrogen production day.
Further, considering that the demand of the user for hydrogen at different time periods is different in practical application, taking a hydrogen station of a bus as an example, a large amount of hydrogen is generally needed in three time periods of morning, midday and evening, and the demand for hydrogen in the rest time periods is obviously lower than the three time periods, so that the hydrogen supply in the time period with a large hydrogen demand needs to be preferentially ensured in the 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 used as the target hydrogen production time interval, and the hydrogen production process is controlled according to the target hydrogen production time interval. The hydrogen production time interval mentioned in this embodiment is obtained by further dividing the target hydrogen production time interval.
Based on the above, it can be seen that the hydrogen production time periods described in the present embodiment belong to the same target hydrogen production time interval, and thus are continuous in time and not discrete time periods.
Optionally, for any hydrogen production power supply, the output power of the hydrogen production power supply 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, and the hydrogen production power input by the hydrogen production device cannot be larger than the rated hydrogen production power of the hydrogen production device, so that it can be known that, for the hydrogen production power supply, the part of the output power of the hydrogen production power supply, which is larger than the rated hydrogen production power of the hydrogen production device, cannot be used for hydrogen production, and therefore, after the predicted power of the hydrogen production power supply 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 supply and the rated hydrogen production predicted power of the hydrogen production device needs to be used as the available hydrogen production predicted power of the hydrogen production power supply in the hydrogen production time period.
Alternatively, referring to fig. 2, fig. 2 is a schematic diagram of the relationship between the output power curve of each hydrogen production power source and the predicted available hydrogen production power curve according to the embodiment of the present invention, as can be seen from fig. 2, the output power of each hydrogen generation power source has different variation characteristics, and at the same time, also shown in figure 2 is the power curve for a wind power system and a photovoltaic power system when used together to produce hydrogen, can be understood as the power curve of a new energy power generation system and the power curve when an alternating current power grid and an energy storage system are jointly used for producing hydrogen, in the power curve corresponding to the new energy power generation system, Pmax corresponds to the maximum hydrogen production power of the hydrogen production device, Pmin corresponds to the minimum hydrogen production power of the hydrogen production device, and regardless of how each hydrogen production power source is distributed, the total hydrogen production power is within the power range corresponding to Pmin and Pmax, and the curve based on the available hydrogen production power obtained in the foregoing manner is shown as the rightmost curve in fig. 2.
It should be noted that each power curve shown in fig. 2 is a schematic diagram, and in practical application, the performance of a specific hydrogen production power supply is taken as a standard.
In order to adjust the hydrogen production power of each hydrogen production power source in the target hydrogen production time interval, specifically to each hydrogen production time period, the embodiment sets a corresponding function proportion for each hydrogen production power source, so in this 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, and the function proportion of each hydrogen production power source in each hydrogen production time period can also be understood as obtaining the function proportion of each hydrogen production power source in each hydrogen production time period, and after obtaining the energy supply proportion of each hydrogen production power source and the available hydrogen production predicted power in each hydrogen production time period, the product of the function proportion and the available hydrogen production predicted power in each hydrogen production time period is respectively calculated, so that the hydrogen production predicted power of each hydrogen production time period of the hydrogen production power source is obtained. It is contemplated that the functional ratio of each hydrogen production power source may use a preset initial value when the present control method is first performed on any one hydrogen production day.
It should be noted that, the processes mentioned in the above description, such as the output power prediction of various hydrogen production power supplies, the hydrogen demand prediction of hydrogen production systems, and the like, can be implemented based on the prior art, and the present invention is not limited thereto.
And S110, adjusting the hydrogen production duration of each hydrogen production power supply to operate at the corresponding hydrogen production prediction power to obtain a plurality of hydrogen production schemes.
As described above, the target hydrogen production time interval mentioned in this embodiment is obtained by dividing a hydrogen production day, and further, any hydrogen production time period is obtained by dividing the target hydrogen production time interval, so that it can be seen that the hydrogen production time period in any hydrogen production time period of any hydrogen production power supply is longest, that is, the time period corresponding to the hydrogen production time period, therefore, adjusting the hydrogen production time period in which each hydrogen production power supply operates at the corresponding hydrogen production prediction power should be adjusted within the time period range of the hydrogen production time period, a hydrogen production scheme operating at the corresponding hydrogen production prediction power for the corresponding hydrogen production time period is obtained by each adjustment, and a plurality of hydrogen production schemes can be obtained by traversing all possible hydrogen production time periods.
Optionally, in the process of adjusting the hydrogen production time, in order to reduce the calculation amount and improve the program execution efficiency, the hydrogen production time may be adjusted according to a certain step length, for example, the hydrogen production time may be adjusted by taking 10 minutes as the step length. Furthermore, the time duration of each hydrogen production time period can be equal or unequal, and in order to simplify the adjustment process, the target hydrogen production time interval can be equally divided to obtain the hydrogen production time periods with equal time duration. Of course, the hydrogen production day can also be taken as a reference, the hydrogen production day is firstly divided into a plurality of hydrogen production time periods, and then the number of the hydrogen production time periods included in the hydrogen production time interval is determined according to the specific range of the hydrogen production time interval.
In conclusion, a plurality of hydrogen production schemes operating at different hydrogen production durations with corresponding predicted hydrogen production power outputs are finally obtained in the step.
And 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 a plurality of 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 the hydrogen production process inevitably has energy loss, 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 hydrogen output in a preset hydrogen production range exists or not, if not, executing S140, and if so, executing S150.
As described above, in the hydrogen production control method provided in this embodiment, in order to ensure that the hydrogen output meets the application requirements, after obtaining the hydrogen output of each hydrogen production scheme, it is determined whether there is a hydrogen production scheme whose hydrogen output is within the preset hydrogen production range, and if so, S150 is executed, and if not, S140 is executed.
It is conceivable that, if the hydrogen production scheme in which the hydrogen production amount is within the preset hydrogen production range includes a plurality of hydrogen production schemes, the hydrogen production scheme in which the hydrogen production amount is the largest should be selected as the target hydrogen production scheme.
And S140, adjusting the hydrogen production predicted power of each hydrogen production power supply.
As mentioned above, the predicted power of each hydrogen production power supply in the hydrogen production day is determined, and the method adjusts the power of each hydrogen production power supply for hydrogen production by adjusting the function proportion, so in the step, the predicted hydrogen production power of each hydrogen production power supply is adjusted by adjusting the function proportion of each hydrogen production power supply, and the step returns to S100 after the adjustment of the predicted hydrogen production power is completed.
It is conceivable that, after returning, the adjusted hydrogen production predicted power of each hydrogen production power source is obtained in S100.
S150, controlling the hydrogen production system to produce hydrogen according to the target hydrogen production scheme.
If a target hydrogen production scheme that the hydrogen output is within a preset hydrogen production range exists, the corresponding hydrogen production power supplies 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 supply in the target hydrogen production scheme to generate hydrogen.
In summary, the hydrogen production control method provided by the invention obtains a plurality of hydrogen production schemes by adjusting the predicted hydrogen production power and the hydrogen production duration of each hydrogen production power supply, controls the hydrogen production system to operate according to the hydrogen production scheme meeting the preset hydrogen production requirement, effectively ensures that the hydrogen yield of the hydrogen production system meets the expected requirement, and solves the problems in the prior art.
Based on the execution process of the hydrogen production control method provided by the embodiment, even if the hydrogen production time is adjusted according to the determined hydrogen production power, the obtained hydrogen production schemes are very many, correspondingly, the calculation of the hydrogen production amount of all the hydrogen production schemes consumes a lot of time, the control efficiency is seriously influenced, and a large amount of hardware resources are occupied. To solve this problem, this embodiment provides another hydrogen production control method based on the embodiment shown in fig. 1, and the specific flow chart thereof can be seen 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 is expanded, and the rest can be referred to the foregoing, and will not be repeated here.
Specifically, a plurality of hydrogen production schemes are obtained by adjusting the hydrogen production duration of each hydrogen production power supply operating at the corresponding hydrogen production power, and the following steps are executed:
and S1201, respectively calculating the hydrogen production contribution value of each hydrogen production scheme.
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 a higher hydrogen production contribution value indicates that the required hydrogen production cost is lower for the same hydrogen production, or a higher hydrogen production contribution value indicates that the amount of hydrogen produced is larger for 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 source in each hydrogen production time period in this embodiment. In this embodiment, the weight coefficient of the hydrogen production power supply is mainly related to the energy capacity of the hydrogen production power supply, 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 conditions such as the unit price of the hydrogen production power supply, the availability convenience of the hydrogen production power supply, and the like, and in practical application, the weight coefficient of the hydrogen production power supply can be set according to the specific situation of the hydrogen production power supply. It is emphasized that the predetermined weighting factors mentioned in this embodiment are inversely related to the hydrogen production cost of the hydrogen production power source in the corresponding hydrogen production time period, i.e., the higher the hydrogen production cost, the smaller the corresponding predetermined weighting factor.
It is conceivable that, for a certain hydrogen production system, the preset weighting coefficients of the wind power generation system, the photovoltaic power generation system and the energy storage system are often fixed, and the electricity price of the alternating current power grid varies at different time intervals, so that the preset weighting coefficients of the alternating current power grid vary at different hydrogen production time intervals.
Based on the above premise, the calculation process of the hydrogen production contribution value is described below by specific examples:
assuming that a hydrogen production power supply of the hydrogen production system comprises an alternating current power grid, an energy storage system, a wind power generation system and a photovoltaic power generation power grid, and the preset weight coefficients of the four hydrogen production power supplies are respectively marked as k1、k2、k3、k4Wherein, as mentioned above, the preset weighting coefficients of the ac power grid in different hydrogen production periods may change due to the change of electricity prices.
Dividing a target hydrogen production time interval into N equal time periods, and respectively marking preset weight coefficients corresponding to the N hydrogen production time periods of the alternating current power grid as k11、k12、…、k1NThe preset weight coefficient of each hydrogen production time period is multiplied by the corresponding predicted hydrogen production power, so that the hydrogen production power vector of the alternating current power grid can be further obtained
Accordingly, the available hydrogen production power vector of the energy storage system is
The hydrogen production power vector of the 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 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 represented as T1j、T2j、T3j、T4jThe process of adjusting the hydrogen production time period should be performed within a time period range corresponding to the hydrogen production time period, that is, the following rules are satisfied:
wherein j represents the jth hydrogen production time period;
TZrepresenting the duration of the target hydrogen production time interval.
The matrix QT represents the hydrogen production contribution of the hydrogen production schedule, and the following calculation formula is shown:
in the above formula, k isijThe value of i is 1 to represent the preset weight coefficient of the alternating current power grid in the jth hydrogen production time period, the value of i is 2 to represent the preset weight coefficient of the energy storage system in each hydrogen production time period, the value of i is 3 to represent the preset weight coefficient of the wind power generation system in each hydrogen production time period, and the value of i is 4 to represent the preset weight coefficient of the photovoltaic power generation system in each hydrogen production time period; wherein P isijThe i values 1, 2, 3 and 4 are the hydrogen production power of the four hydrogen production power sources in the jth hydrogen production time period respectively.
Further calculation of the above matrix includes:
based on the above formula, when calculating the hydrogen production contribution value of the hydrogen production scheme, the hydrogen production contribution sub-values of the hydrogen production scheme in each hydrogen production time period can be calculated respectively, that is, the hydrogen production contribution sub-value is calculated according to the preset weight coefficient, the hydrogen production predicted power and the hydrogen production duration of each hydrogen production power supply 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 power supply in each hydrogen production time period is calculated to obtain the corresponding first calculation result, where k is given as an example in the above formula11P11T11Namely one of the first calculation results, and then respectively calculating the sum of the first calculation results corresponding to the same hydrogen production time period to obtain the hydrogen production contributor value of the hydrogen production scheme in the corresponding hydrogen production time period, taking the above formula as an example, wherein k is in the above formula11P11T11+k2P21T21+k3P31T31+k4P41T41And further calculating the sum of the hydrogen production contribution sub-values of each hydrogen production power supply in each hydrogen production time period to obtain the hydrogen production contribution value of the scheme, wherein the obtained result is the hydrogen production contribution sub-value of each hydrogen production power supply in the first hydrogen production time period, and the hydrogen production contribution value can be specifically expressed as follows:
qt＝k11P11T11+k2P21T21+k3P31T31+k4P41T41+k12P12T12+k2P22T22+
k3P32T32+k4P42T42+L+k1NP1NT1N+k2P2NT2N+k3P3NT3N+k4P4NT4N
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 each hydrogen production scheme, if not, executing S1203, and if so, executing S1204.
In each obtained hydrogen production scheme, each hydrogen production scheme is screened according to the size relation between the hydrogen production contribution value corresponding to the hydrogen production scheme and 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 contribution value is kept as a candidate hydrogen production scheme, and if the hydrogen production contribution value of the hydrogen production scheme is smaller than or equal to the preset threshold value, the candidate hydrogen production scheme is discarded without use. Based on this, S1203 is executed if the hydrogen production contribution values of the respective hydrogen production schemes are less than or equal to a preset threshold value, and S1204 is executed if there is at least one candidate hydrogen production scheme having a hydrogen production contribution value greater than the preset threshold value.
It should be noted that, for the preset threshold, specific control accuracy and actual application requirement setting may be combined, and the specific setting of the preset threshold is not limited in the present invention.
And S1203, adjusting the hydrogen production predicted power of each hydrogen production power supply.
Alternatively, the execution of S1203 may be realized by referring to S140 in the embodiment shown in fig. 1, which is not repeated here, and after the adjustment of the predicted hydrogen production power is completed, the process returns to S100.
And 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, in order to obtain better hydrogen production yield, the candidate hydrogen production scheme with the largest hydrogen production contribution value in the candidate hydrogen production schemes is selected as the target hydrogen production scheme.
And S1205, calculating the hydrogen output of the target hydrogen production scheme.
As mentioned above, the hydrogen production apparatus may first calculate the hydrogen production power supply amount of the target hydrogen production scheme after determining the target hydrogen production scheme corresponding to the preset conversion efficiency in the hydrogen production process, specifically, may calculate according to the following formula:
Q＝P11T11+P21T21+P31T31+P41T41+L+P1NT1N+P2NT2N+P3NT3N+P4NT4N
and 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 calculation can be performed by referring to the following formula:
Hq＝δ(P11T11+P21T21+P31T31+P41T41+L+P1NT1N+P2NT2N+P3NT3N+P4NT4N)
it is conceivable that after the hydrogen output of the target hydrogen production scheme is obtained, the step S130 directly determines whether the hydrogen output of the target hydrogen production scheme is within the preset hydrogen production range, and the calculation of the hydrogen output and subsequent steps are not necessary for the remaining schemes, so that the calculation amount can be effectively reduced, and the control efficiency can be improved. For the execution process of the rest steps, reference may be made to the corresponding content in the embodiment shown in fig. 1, and details are not described here.

And S1004, controlling the new energy power generation system to supply power to the hydrogen production device, and controlling the energy storage system to be in a charging mode.
Under the condition that the hydrogen production requirement can be met by utilizing the output power of the photovoltaic power generation system and the wind power generation system, the wind power generation system and the photovoltaic power generation system are controlled to supply power to the hydrogen production device, the specific hydrogen production process can be realized by referring to the prior art, and the hydrogen production process is not unfolded.
Meanwhile, the energy storage system is controlled to be in a charging mode, it is conceivable that the energy storage system can play a role of a buffer pool with more charge and less supplement in the whole hydrogen production system, the output power of the photovoltaic power generation system and the wind power generation system can at least meet the hydrogen production requirement, and if the output power of the photovoltaic power generation system and the wind power generation system is further remained, the hydrogen production system can be stored in the energy storage system.
As for the execution process of the remaining steps after S1003 shown in fig. 4, all the steps can be implemented with reference to the embodiment shown in fig. 1, and the description of the embodiment is not repeated.
