Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.
[0080] First, let’s analyze some of the terms used in this application:
[0081] Electrolytic Cell: An electrolytic cell is a device used to perform the electrolysis process, where a chemical reaction is induced by applying an electric current through an electrolyte. It consists of an anode and a cathode separated by an electrolyte solution, which facilitates the movement of ions during the electrolysis process.
[0082] Overload refers to a situation where the current, power, or load on electrical equipment or systems exceeds their rated operating capacity for a given period of time. This can occur for a short period of time (a transient overload) or for an extended period. Overload can cause equipment performance degradation, damage, or pose a safety risk.
[0083] A load is the current, power, or energy absorbed by a device, appliance, or circuit connected to a power system. The load is the terminal at which the power system delivers power, through which electrical energy is converted into the required work, heat, or other forms of energy.
[0084] With the development of energy technology, more and more people are paying more attention to the efficient development of clean energy. Water electrolysis hydrogen production technology is a clean energy storage technology developed by the mutual conversion of electricity and hydrogen energy. It is regarded as one of the key technologies to solve the energy crisis and absorb renewable energy.
[0085] Among the existing technologies, most of the hydrogen production technologies using electrolysis of water use alkaline water electrolysis technology. Although the technology is very mature, it still has problems such as slow dynamic hydrogen production response and low hydrogen production efficiency caused by hydrogen production through a single electrolyzer. In addition, its controllability and stability are also limited, which is not conducive to mutual cooperation with renewable energy with rapid fluctuation characteristics.
[0086] Based on this, the embodiment of the present application provides a multi-electrolyzer hybrid hydrogen production control method and power generation system, which obtains the electrolysis power parameters of multiple electrolyzers and the real-time power generation power of the power generation system, and then controls multiple electrolyzers to repeatedly perform electrolysis start and stop operations in sequence according to the multiple electrolysis power parameters and the real-time power generation power. In each electrolysis start and stop operation: the target round startup output power is compared with the rated minimum electrolysis power of the target electrolyzer. When the target round startup output power is greater than or equal to the rated minimum electrolysis power of the target electrolyzer, the target electrolyzer is controlled to start and perform electrolysis work, and the corresponding electrolyzer is controlled to perform electrolysis based on the target position sequence of the target electrolyzer. Perform the next electrolysis start-stop operation; when the target round startup output power is less than the rated minimum electrolysis power of the target electrolyzer, determine whether the target round startup output power exceeds the danger warning threshold power. When the target round startup output power exceeds the danger warning threshold power, the corresponding electrolyzer is controlled to stop the electrolysis work based on the target position sequence of the target electrolyzer, and perform the next electrolysis start-stop operation; when the target round startup output power does not exceed the danger warning threshold power, the target electrolyzer is controlled to perform the next electrolysis start-stop operation; thereby improving the hydrogen production efficiency and flexibility of multiple electrolyzers in the hydrogen production power generation system, and improving the stability and service life of the hydrogen production power generation system.
[0087] A multi-electrolyzer hybrid hydrogen production control method and power generation system provided in an embodiment of the present application are specifically illustrated through the following embodiments. First, a multi-electrolyzer hybrid hydrogen production control method in an embodiment of the present application is described.
[0088] 1 , which is a flow chart of a multi-electrolyzer hybrid hydrogen production control method provided in some embodiments of the present application, the multi-electrolyzer hybrid hydrogen production control method may include but is not limited to steps S110 to S120 .
[0089] Step S110: Obtain electrolysis power parameters of multiple electrolytic cells and the real-time power generation power of the power generation system; the electrolysis power parameters include the rated minimum electrolysis power and the rated electrolysis power.
[0090] Specifically, in the process of obtaining the electrolysis power parameters of multiple electrolytic cells, the rated electrolysis powers of the multiple electrolytic cells can be the same or different. For example, if there are 4 electrolytic cells, the rated electrolysis powers of the 4 electrolytic cells can all be 0.5MW, or two of the electrolytic cells can be 0.5MW and the other two can be 1.5MW.
[0091] Step S120: controlling the plurality of electrolytic cells to repeatedly perform electrolysis start and stop operations in sequence according to the plurality of electrolysis power parameters and the real-time power generation power.
[0092] Specifically, it should be noted that, with reference to Figure 2, Figure 2 is a schematic diagram of a method for sequentially repeating electrolysis start and stop operations of multiple electrolytic cells provided in other embodiments of the present application. It can be seen from Figure 2 that sequentially repeating the electrolysis start and stop operations is to cyclically execute the electrolysis start and stop operations according to the ranking sequence of multiple electrolytic cells.
[0093] 3 , FIG3 is a flowchart of an electrolysis start-stop operation in step S120 in FIG1 provided in other embodiments of the present application. The electrolysis start-stop operation may include but is not limited to steps S310 to S350.
[0094] Step S310: Compare the target round startup output power with the rated minimum electrolysis power of the target electrolytic cell to obtain the target round startup result.
[0095] It should be noted that the target round startup output power Pa is the difference between the real-time power generation power Pg and the sum of the rated electrolysis powers Pel of all currently working electrolytic cells, that is, Pa = Pg - Pel. Among them, the working electrolytic cell is the electrolytic cell performing electrolysis work.
[0096] It should also be noted that, assuming that there are k working electrolytic cells, the total number of electrolytic cells is N, and the rated electrolytic power Pi of the working electrolytic cell Eli, the sum of the rated electrolytic powers of all the working electrolytic cells is The formula for obtaining the target round startup output power is as follows:
[0097] Step S320: When the target round startup result is that the target round startup output power is greater than or equal to the rated minimum electrolysis power of the target electrolytic cell, the target electrolytic cell is controlled to start and perform electrolysis work, and the corresponding electrolytic cell is controlled to perform the next electrolysis start and stop operation based on the target position sequence of the target electrolytic cell.
[0098] Specifically, when the target round startup output power Pa is greater than or equal to the rated minimum electrolysis power Ps of the target electrolytic cell (k), the target electrolytic cell is controlled to start performing electrolysis work (that is, the current working electrolytic cell is k=k+1), and the corresponding electrolytic cell is controlled based on the target position sequence of the target electrolytic cell to perform the next electrolysis start and stop operation.
[0099] Step S330: When the target round start result is that the target round start output power is less than the rated minimum electrolysis power of the target electrolytic cell, it is determined whether the target round start output power exceeds the danger warning threshold power, and the target round stop result is obtained.
[0100] It should be noted that the dangerous warning threshold power Pd is a negative power, and the absolute value of the dangerous warning threshold power Pd is equal to 75% of Ps (i.e., |Pa| = 0.75Ps). When the starting output power Pa of the target round is less than the rated minimum electrolysis power Ps of the target electrolytic cell, it is determined whether the starting output power Pa of the target round exceeds the dangerous warning threshold power Pd (i.e., it is determined whether Pa is less than Pd), and the stopping result of the target round is obtained.
[0101] Step S340: When the stopping result of the target round is that the starting output power of the target round exceeds the dangerous warning threshold power, control the corresponding electrolytic cell corresponding to the target electrolytic cell to stop performing electrolysis work, and perform the next electrolysis start-stop operation.
[0102] Specifically, if the starting output power of the target round exceeds the dangerous warning threshold power (i.e., Pa < Pd = -0.75Ps), control the corresponding electrolytic cell corresponding to the target electrolytic cell to stop performing electrolysis work (i.e., the current working electrolytic cell is k = k - 1), and perform the next electrolysis start-stop operation.
[0103] Step S350: When the stopping result of the target round is that the starting output power of the target round does not exceed the dangerous warning threshold power, control the target electrolytic cell to perform the next electrolysis start-stop operation.
[0104] Specifically, if the starting output power of the target round does not exceed the dangerous warning threshold power (i.e., Pa ≥ Pd = -0.75ps), control the target electrolytic cell to perform the next electrolysis start-stop operation (i.e., the current working electrolytic cell is k).
[0105] Referring to FIG. 4, FIG. 4 is a flowchart of step S330 in FIG. 3 provided by some other embodiments of the present application. The electrolysis start-stop operation may include, but is not limited to, steps S410 to S430.
[0106] Step S410: Determine whether the target position sequence is the last sequence, and obtain the first position sequence result.
[0107] Specifically, determine whether the target position sequence of the target electrolytic cell is the last Nth sequence among N electrolytic cells, and obtain the first position sequence result.
[0108] Step S420: When the first position sequence result is that the target position sequence is the last sequence, control the target electrolytic cell to perform the next electrolysis start-stop operation.
[0109] Specifically, when the first position sequence result is that the target position sequence is the last sequence, control the current target electrolytic cell (i.e., the k = Nth electrolytic cell) to repeatedly perform the next electrolysis start-stop operation.
[0110] Step S430: When the first position sequence result is that the target position sequence is not the end sequence, controlling the subsequent electrolytic cell based on the target electrolytic cell to perform the next electrolysis start and stop operation.
[0111] Specifically, when the first position sequence result is that the target position sequence is not the end sequence, the subsequent electrolytic cell (ie, the k+1th electrolytic cell) of the current target electrolytic cell is controlled to perform the next electrolysis start-stop operation.
[0112] Referring to FIG. 5 , FIG. 5 is a flowchart of step S330 in FIG. 3 provided in other embodiments of the present application. The electrolysis start-stop operation may include but is not limited to steps S510 to S530 .
[0113] Step S510: determining whether the target position sequence is a header sequence, and obtaining a second position sequence result;
[0114] Specifically, it is determined whether the target position sequence of the target electrolytic cell is the first sequence at the beginning among the N electrolytic cells, and a second position sequence result is obtained.
[0115] Step S520: When the first position sequence result is that the target position sequence is a head sequence, the target electrolytic cell is controlled to stop performing the electrolysis work, and after stopping the electrolysis work, the next electrolysis start-stop operation is performed.
[0116] Specifically, when the first position sequence result is that the target position sequence is the head sequence, the target electrolytic cell (ie, the k=1th electrolytic cell) is controlled to stop performing the electrolysis work, and then the next electrolysis start-stop operation is performed after the electrolysis work is stopped.
[0117] Step S530: When the first position sequence result is that the target position sequence is not the head sequence, the preceding electrolytic cell based on the target electrolytic cell is controlled to stop performing the electrolysis work, and the next electrolysis start-stop operation is performed after the electrolysis work is stopped.
[0118] Specifically, when the first position sequence result is that the target position sequence is the head sequence, the control is based on the preceding electrolytic cell (i.e., the k=k-1th electrolytic cell) of the target electrolytic cell to stop performing electrolysis work, and after stopping the electrolysis work, the next electrolysis start-stop operation is performed.
[0119] 6 , which is a flow chart of a multi-electrolyzer hybrid hydrogen production control method provided in some other embodiments of the present application, the electrolysis start-stop operation may include but is not limited to steps S610 to S620 .
[0120] Step S610: Acquire the real-time operating parameters of all working electrolytic cells.
[0121] Specifically, the real-time working parameters include the real-time working duration, the minimum working cycle and the minimum cycle cumulative count. The initial count value of the minimum cycle cumulative count Tt is 0.
[0122] Step S620: Asynchronously perform electrolysis load balancing operations on corresponding working electrolytic cells according to all real-time working cycle parameters.
[0123] Specifically, in actual operation, imbalances in the operating hours of electrolyzers can accelerate the aging of multi-electrolyzer hybrid hydrogen production modules, leading to the premature replacement or repair of some electrolyzers and even the unavoidable interruption of production. By asynchronously performing electrolysis load balancing operations on the corresponding active electrolyzers, each electrolyzer can operate under similar external conditions, reducing the risk of system module performance degradation due to uneven operating hours and improving the stability and durability of the system modules.

[0125] Step S710: Determine whether the working time of the target working electrolytic cell reaches the corresponding minimum working cycle, and obtain the load switching result.
[0126] Specifically, it is determined whether the working time Tw of the target working electrolytic cell (ie, the kth cell) reaches the corresponding minimum working period Tmin, and the load switching result is obtained.
[0127] Step S720: When the load switching result indicates that the working time of the target electrolytic cell reaches the corresponding minimum working cycle, the target switching electrolytic cell is obtained based on the minimum cycle cumulative count of the target working electrolytic cell and the matching of the position sequence among the multiple electrolytic cells that have stopped performing electrolysis work, and the preset cumulative value is added to the minimum cycle cumulative count of the target working electrolytic cell;
[0128] It should be noted that the preset cumulative value is a positive value, which can be 1, 2, or 3, and this application does not make any specific limitations.
[0129] At the same time, the target working electrolytic cell is matched with the minimum cycle cumulative count Tt and position sequence (i.e., the kth) of the target working electrolytic cell among the multiple electrolytic cells (i.e., Nk) that have stopped performing electrolysis, and the target switching electrolytic cell is obtained. The matching rule is to match the target switching electrolytic cell that is currently closest to the target working electrolytic cell according to the arrangement order of the electrolytic cells.
[0130] Step S730: According to the matched target switching electrolytic cell, the target working electrolytic cell is controlled to stop performing electrolysis work, and the target switching electrolytic cell is controlled to start performing electrolysis work.
[0131] Specifically, according to the matched target switching electrolytic cell, the target working electrolytic cell (ie, the kth one) is controlled to stop performing electrolysis work, and the target switching electrolytic cell is controlled to start performing electrolysis work.
[0132] It should also be noted that the minimum cycle cumulative count of the target switching electrolytic cell is less than the minimum cycle cumulative count of the target electrolytic cell, and the position distance value between the target switching electrolytic cell and the target electrolytic cell is less than the position distance value between other electrolytic cells that stop performing electrolysis work and the target electrolytic cell.
[0133] Please refer to Figures 9 and 10. Figure 9 is a structural diagram of a wind-photovoltaic complementary power generation system provided in some embodiments of the present application. Figure 10 is a structural diagram of another wind-photovoltaic complementary power generation system provided in some embodiments of the present application. The wind-photovoltaic complementary power generation system 900 can implement the above-mentioned multi-electrolyzer hybrid hydrogen production control method. The wind-photovoltaic complementary power generation system 900 includes:
[0134] The multi-electrolyzer hybrid hydrogen production module 910 is used to execute the multi-electrolyzer hybrid hydrogen production control method as described above, and to provide energy for electrolyzing water to produce hydrogen according to the multi-electrolyzer hybrid hydrogen production control method; the wind power generation module 920 is used to provide energy for the multi-electrolyzer hybrid hydrogen production module 910; the photovoltaic power generation module 930 is used to provide energy for the multi-electrolyzer hybrid hydrogen production module 910; the power storage module 940 is used to store overload electric energy of the wind power generation module 920 and / or the photovoltaic power generation module 930; the power generation control module 950 is used to control the wind power generation module 920 and / or the photovoltaic power generation module 930 to provide electric energy to the multi-electrolyzer hybrid hydrogen production module 910. Energy, and control the power storage module 940 to balance the overload power of the multi-electrolyzer hybrid hydrogen production module 910; the power generation control module 950 is respectively connected to the wind power generation module 920, the photovoltaic power generation module 930, the power storage module 940 and the multi-electrolyzer hybrid hydrogen production module 910; the hydrogen storage module 960, the hydrogen storage module 960 is used to store the hydrogen energy generated by the multi-electrolyzer hybrid hydrogen production module, the hydrogen storage module 960 is connected to the multi-electrolyzer hybrid hydrogen production module 910, and the hydrogen storage module 960 is connected to the power generation control module 950; the hydrogen power generation module 970, the hydrogen power generation module 970 is used to burn the hydrogen energy in the hydrogen storage module 960 to provide electrical energy, the hydrogen power generation module 970 is connected to the hydrogen storage module 960, and the hydrogen power generation module 970 is connected to the power generation control module 950.
[0135] It should be noted that the energy storage module 940 can maintain the energy fluctuation balance of the wind-solar complementary power generation system by storing overload electric energy. At the same time, it can also store the generated excess electric energy and release it when needed. Thereby, the system can operate more stably and can provide renewable energy to the power transmission grid at any time. When the power generation of the wind power generation module 920 or the photovoltaic power generation module 930 is low, the energy storage module 940 can discharge to provide voltage, thereby maintaining the constancy of the voltage of the power transmission grid. When the power generation of the wind power generation module 920 or the photovoltaic power generation module 930 is strong, charging the energy storage module 940 is equivalent to a load, thereby maintaining the constancy of the grid voltage.
[0136] Referring to FIG. 11, FIG. 11 is a flowchart of a wind-solar complementary energy supply control method provided by some embodiments of the present application, which is applied to the power generation control module 950 of the wind-solar complementary power generation system as described above. The wind-solar complementary energy supply control method may include, but is not limited to, steps S1110 to step S1140.
[0137] Step S1110: Obtain the grid-rated output power of the power transmission grid, and the total real-time power generation output power of the wind power generation module and the photovoltaic power generation module.
[0138] Specifically, the total real-time power generation output power Po of the wind power generation module 920 and the photovoltaic power generation module 930 is the sum of the real-time power generation output power P1 of the wind power generation module 920 and the real-time power generation output power P2 of the photovoltaic power generation module 930.
[0139] Step S1120: Determine whether the total real-time power generation output power meets the grid-rated output power, and obtain a first power supply judgment result.
[0140] Step S1130: When the first power supply judgment result is that the total real-time power generation output power does not meet the grid-rated output power, control the combination between the energy storage module or the hydrogen storage module and the hydrogen energy power generation module to perform power generation compensation, obtain the compensation power generation, and use the compensation power generation and the total real-time power generation output power as the rated transmission power to supply power to the power transmission grid.
[0141] Among them, when the total real-time power generation output power does not meet the grid-rated output power (i.e., Po < Pq), the compensation power generation P3 and the total real-time power generation output power Po are used as the rated transmission power Pq <00000 ‘ to supply power to the power transmission grid. The compensation power supply P3 is the difference between the grid-rated output power Pq and the total real-time power generation output power Po, that is, (P3 = Pq - Po).
[0142] Specifically, the hydrogen storage module 960 delivers hydrogen to the hydrogen energy power generation module 970, and the hydrogen energy power generation module 970 generates power for compensation by burning hydrogen, obtaining the compensation power generation P3.
[0143] Step S1140: When the first power supply judgment result is that the total real-time power generation output power meets the grid's rated output power, the sub-power of the total real-time power generation output power that is equal to the grid's rated output power is used as the rated transmission power to supply power to the transmission grid, and the sub-power of the total real-time power generation output power that exceeds the grid's rated output power is used as the total storage power for subsequent power storage operations.
[0144] Specifically, the total real-time power generation output power meets the grid rated output power (i.e., Po ≥ Pq), the sub-power of the total real-time power generation output power Po that is equal to the grid rated output power Pq is used as the rated transmission power Pq' to supply power to the transmission grid, and the sub-power of the total real-time power generation output power Po that exceeds the grid rated output power is used as the total storage power Pr for subsequent power storage operations.
[0145] 12 , which is a flowchart of subsequent power storage operations provided by other embodiments of the present application, the subsequent power storage operations may include but are not limited to steps S1210 to S1260 .
[0146] Step S1210: Obtain the energy supply overload power and energy supply minimum load power of the multi-electrolyzer hybrid hydrogen production module.
[0147] It should be noted that the energy supply overload power Pmax is greater than the energy supply minimum load power Pmin.
[0148] Step S1220: Determine whether the total stored power exceeds the minimum load power for energy supply, and obtain a first stored power determination result.
[0149] Step S1230: When the first power storage judgment result is that the total power storage power does not exceed the minimum load power of energy supply, the total power storage power is used as the input power of the power storage module to supply power to the power storage module.
[0150] Specifically, when the total storage power Pr does not exceed the minimum load power Pmin (i.e., Pr≤Pmin), it indicates that the wind-photovoltaic complementary power generation system is in cloudy and weak wind weather, resulting in insufficient power generation. The total storage power Pr is then used as the input power of the storage module 940 to supply power to the storage module 940.
[0151] Step S1240: When the first power storage judgment result is that the total power storage power exceeds the minimum power supply load power, determine whether the total power storage power exceeds the power supply overload power to obtain a second power storage judgment result.
[0152] It should be noted that the total storage power Pr exceeds the minimum load power Pmin, that is, Pr>Pmin. It also shows that the wind-photovoltaic complementary power generation system is fully generating electricity in weather with sufficient sunlight and strong winds.
[0153] Step S1250: When the second power storage judgment result is that the total real-time power generation output power does not exceed the energy supply overload power, the total power storage power is used as the input power of the multi-electrolyzer hybrid hydrogen production module to supply power to the multi-electrolyzer hybrid hydrogen production module.
[0154] Specifically, when the total storage power Pr does not exceed the energy supply overload power Pmax (i.e., Pr≤Pmax), it indicates that the multi-electrolyzer hybrid hydrogen production module 910 is operating at normal power, and the total storage power is used as the input power of the multi-electrolyzer hybrid hydrogen production module 910 to power the multi-electrolyzer hybrid hydrogen production module 910.
[0155] Step S1260: When the second power storage judgment result is that the total power storage power exceeds the energy supply overload power, the sub-power of the total power storage power that is equal to the energy supply overload power is used as the input power of the multi-electrolyzer hybrid hydrogen production module to supply power to the multi-electrolyzer hybrid hydrogen production module, and the sub-power of the total real-time power generation output power that exceeds the energy supply overload power is used as the input power of the power storage module to supply power to the power storage module.
[0156] Specifically, when the total storage power Pr exceeds the minimum load power Pmax of the energy supply (i.e., Pr>Pmax), it indicates that the multi-electrolyzer hybrid hydrogen production module 910 is operating at full load, and the sub-power of the total real-time power generation output power exceeding the energy supply overload power is used as the input power of the storage module 940 to supply power to the storage module 940.
[0157] 13 , which is a flowchart of step S1130 in FIG. 11 provided in some other embodiments of the present application, the wind-solar-photovoltaic complementary energy supply control method may include but is not limited to steps S1310 to S1330 .
[0158] Step S1310: Determine whether the total real-time power generation output power exceeds a zero value, and obtain a second power supply determination result.
[0159] Step S1320: When the second power supply judgment result is that the total real-time power generation output power exceeds zero, the power storage module is controlled to perform power generation compensation to obtain the compensated power generation power.
[0160] It should be noted that the total real-time power generation output power Pr exceeds zero (i.e., Pr>0), indicating that the wind-photovoltaic complementary power generation system is temporarily in rainy and windless weather, resulting in insufficient power generation. The power storage module 940 is controlled to perform power generation compensation to obtain the compensated power generation power P3.
[0161] Step S1330: Alternatively, when the second power supply judgment result is that the total real-time power generation output power does not exceed the zero value, the combination block between the hydrogen storage module and the hydrogen energy power generation module is controlled to perform power generation compensation to obtain the compensated power generation power.
[0162] It should be noted that the total real-time power generation output power Pr does not exceed zero (i.e., Pr≤0), indicating that the wind-photovoltaic complementary power generation system is continuously in rainy and windless weather and is unable to generate electricity. In this case, the combination block between the hydrogen storage module 960 and the hydrogen energy power generation module 950 is controlled to perform power generation compensation to obtain the compensated power generation power P3.
