[0002] In the field of wind power hydrogen production, due to the high cost of off-grid power channels, local consumption has become an important solution for the development of wind power resources. Due to the cost control of batteries that are only suitable for short-term energy storage characteristics and the requirements for cycle life, the battery capacity configuration is often reduced, which makes the battery unable to assume the main peak power function.

[0048] The following is a detailed description of an electrolytic cell cluster control method provided in an embodiment of the present application.

[0049] Reference Figure 1 As shown, it is a flow chart of a method for controlling an electrolytic cell cluster provided in an embodiment of the present application. The exemplary steps of the embodiment of the present application are described below:

[0050] S101, obtaining the actual total power of the current electrolytic cell group corresponding to the electrolytic cell cluster, the target total cell group power increment, the electrolytic cell group operation boundary, the planned operation number of the electrolytic cell group at the next moment, and the actual start and stop status of each electrolytic cell group.

[0051] In an embodiment of the present application, the electrolytic cell cluster includes at least one electrolytic cell group, and each electrolytic cell group includes a plurality of electrolytic cells. The actual total power of the electrolytic cell group corresponding to the electrolytic cell cluster refers to the sum of the actual powers of all electrolytic cell groups in the electrolytic cell cluster, which can be converted by the current actual wind power. The target total cell group power increment and the planned operation number of the electrolytic cell group are obtained by planning based on the wind power at the next moment; the target total cell group power increment refers to the value obtained by subtracting the actual total power of the electrolytic cell group from the planned total power of the electrolytic cell group at the next moment of the upper-level planning corresponding to the electrolytic cell cluster (planned based on the wind power at the next moment). The planned operation number of the electrolytic cell group refers to the number of electrolytic cell groups running at the next moment in the electrolytic cell cluster planned by the upper layer. The start-stop state includes the shutdown state and the running state; the running state includes the startup state (the state in which the target power cannot be received) and the target working state (the state in which the target power can be received); the target working state includes the static tank state and the dynamic tank state; the dynamic tank state includes the dynamic tank load increase and decrease state, and the dynamic tank leveling state.

[0052] Among them, the static tank state means that the target power assigned to the tank group does not change over time. The dynamic tank state means that the target power assigned to the electrolytic cell group changes over time. Dynamic tank leveling means that the electrolytic cell group is assigned a leveling function, and the power change is random. The dynamic tank load-up and load-down state means that a fixed load-up and load-down rate is assigned, and the power change is determined.

[0053] In addition, the electrolytic cell group operating boundaries include an upper operating power limit power boundary, a lower operating power limit power boundary, a load-up ramp power boundary, and a load-down ramp power boundary.

[0054] Among them, the upper limit power boundary of operating power = the number of electrolytic cell groups currently in operation * the rated power of the electrolytic cell group + the number of electrolytic cell groups currently in the startup state * the startup power of the electrolytic cell group. The lower limit power boundary of operating power = the number of electrolytic cell groups currently in operation * the lower limit power of the electrolytic cell group + the number of electrolytic cell groups currently in the startup state * the startup power. The load-up ramp power boundary = the number of electrolytic cell groups currently in operation * the maximum load-up ramp rate of the electrolytic cell group. The load-down ramp power boundary = the number of electrolytic cell groups currently in operation * the maximum load-down ramp power of the electrolytic cell group.

[0055] S102. According to the numerical relationship between the actual total power of the electrolytic cell group and the operating boundary of the electrolytic cell group, the planned operating number of the electrolytic cell group and the actual start / stop status of each electrolytic cell group, a start / stop status instruction is issued to the electrolytic cell groups in the electrolytic cell cluster, so that the electrolytic cell groups operate according to the start / stop status instruction.

[0056] In the implementation manner of the present application, the start-stop state instruction includes a start instruction, a shutdown instruction and a normal operation instruction. The normal operation instruction refers to an instruction to operate within a normal power working range.

[0057] Specifically, the start and stop status instructions are issued to the electrolytic cell groups in the electrolytic cell cluster through the following steps:

[0058] Step 1: Determine the target number of electrolytic cell groups in operation at the next moment in the electrolytic cell cluster according to the numerical relationship between the actual total power of the electrolytic cell group and the operation boundary of the electrolytic cell group and the planned operation number of the electrolytic cell group.

[0059] In the embodiment of the present application, the target number of electrolytic cell groups in operation at the next moment refers to the number of electrolytic cell groups in operation in the electrolytic cell cluster at the next moment.

[0060] Here, the target number of electrolytic cell groups in operation at the next moment is determined by the following steps:

[0061] a. If the actual total power of the electrolytic cell group is within the operating boundary of the electrolytic cell group, the first planned start-up quantity is increased by one to obtain the first initial electrolytic cell group operating quantity; otherwise, the first planned start-up quantity is determined as the first initial electrolytic cell group operating quantity.

[0062] In an embodiment of the present application, it is determined whether the actual total power of the electrolytic cell group is greater than the upper limit power boundary of the operating power or less than the lower limit power boundary of the operating power; if the actual total power of the electrolytic cell group is greater than the upper limit power boundary of the operating power or less than the lower limit power boundary of the operating power, the first planned opening quantity is increased by one to obtain the first initial electrolytic cell group operation quantity; if the actual total power of the electrolytic cell group is less than or equal to the upper limit power boundary of the operating power and greater than or equal to the lower limit power boundary of the operating power, it is determined whether the actual total power of the electrolytic cell group is greater than the load climbing power boundary or less than the load reducing climbing power boundary; if the actual total power of the electrolytic cell group is greater than the load climbing power boundary or less than the load reducing climbing power boundary, the first planned opening quantity is increased by one to obtain the first initial electrolytic cell group operation quantity; if the actual total power of the electrolytic cell group is less than or equal to the load climbing power boundary and greater than or equal to the load reducing climbing power boundary, the first planned opening quantity is determined as the first initial electrolytic cell group operation quantity.

[0063] b. Determine the second initial electrolytic cell group operation quantity based on the difference between the second planned start-up quantity and the first planned start-up quantity.

[0064] In an embodiment of the present application, the difference obtained by subtracting the first planned start-up number from the second planned start-up number is determined as the standby number of the electrolytic cell group; if the standby number of the electrolytic cell group is equal to 0, the first planned start-up number is determined as the second initial electrolytic cell group operation number; if the standby number of the electrolytic cell group is greater than 0, the predicted wind power after the shortest time for the electrolytic cell group with the standby number of the electrolytic cell group to run from the startup state to the target working state is predicted based on the wind force prediction model; the predicted wind power is subtracted from the current actual wind power to obtain the wind power fluctuation power; the total fluctuating power of the electrolytic cell group corresponding to the wind power fluctuation power is determined from the historical fluctuation data; if the total fluctuating power of the electrolytic cell group is greater than 0 and the actual total power of the electrolytic cell group does not meet the upper limit power boundary and the upper limit climbing capacity under the first planned start-up number, the first planned start-up number is increased by one to obtain the second initial electrolytic cell group operation number; if the total fluctuating power of the electrolytic cell group is less than or equal to 0 or the actual total power of the electrolytic cell group meets the upper limit power boundary and the upper limit climbing capacity under the first planned start-up number, the first planned start-up number is determined as the second initial electrolytic cell group operation number.

[0065] The historical fluctuation data includes the total fluctuating power of the electrolyzer group corresponding to each wind power fluctuation power.

[0066] c. Determine the maximum value of the first initial electrolytic cell group operating quantity and the second initial electrolytic cell group operating quantity as the target electrolytic cell group operating quantity.

[0067] Step 2: according to the actual start / stop status of each electrolytic cell group, the numerical relationship between the number of electrolytic cell groups whose actual start / stop status is the running status and the target number of running electrolytic cell groups, a start / stop status instruction is issued to the electrolytic cell groups in the electrolytic cell cluster.

[0068] In an embodiment of the present application, if the number of electrolytic cell groups whose actual start-stop state is the running state is greater than the target number of running electrolytic cell groups, it is determined whether there is an electrolytic cell group whose actual start-stop state is the starting state. If there is an electrolytic cell group whose actual start-stop state is the starting state, a shutdown command is issued to any electrolytic cell group in the starting state; if there is no electrolytic cell group whose actual start-stop state is the starting state, a shutdown command will be issued to the electrolytic cell group in the running state with the shortest shutdown time.

[0069] In addition, when the electrolytic cell group is required to stop urgently due to sudden failure of the wind turbine, sudden weather causing serious shortage of wind power load, etc., it is determined whether there is an electrolytic cell group that needs to enter the shutdown state and is currently in the operating state in the current electrolytic cell group scheduling information planned by the upper layer. If there is an electrolytic cell group that needs to enter the shutdown state and is currently in the operating state, a shutdown command is issued to any electrolytic cell group that needs to enter the shutdown state and is currently in the operating state; if there is no electrolytic cell group that needs to enter the shutdown state, a shutdown command is issued to the electrolytic cell group in the operating state with the shortest remaining life.

[0070] The remaining life of the electrolytic cell group is calculated based on the number of starts and stops and the operating time of the electrolytic cell group.

[0071] If the number of electrolytic cell groups in the actual start-stop state is equal to the target number of electrolytic cell groups in operation, a normal operation instruction is issued to the electrolytic cell groups in the electrolytic cell cluster.

[0072] If the number of electrolytic cell groups in the actual start-stop state is less than the target number of electrolytic cell groups in operation, determine whether there is an electrolytic cell group that needs to enter the operating state and is currently in the shutdown state in the current electrolytic cell group scheduling information planned by the upper layer. If there is an electrolytic cell group that needs to enter the operating state and is currently in the shutdown state, a startup instruction is issued to any electrolytic cell group that needs to enter the operating state and is currently in the shutdown state; if there is no electrolytic cell group that needs to enter the operating state and is currently in the shutdown state, a startup instruction is issued to the electrolytic cell group that has the shortest running time from the startup state to the target working state and is currently in the shutdown state.

[0073] In addition, when the electrolytic cell group is required to start up quickly due to sudden failure of the wind turbine group, sudden weather causing serious overload of wind power, etc., a startup command is issued to the electrolytic cell group that has the shortest running time from the startup state to the target working state and is currently in the shutdown state.

[0074] The running time from the start-up state to the target working state is determined according to the temperature of the electrolytic cell group. The running time from the start-up state to the target working state is different for different temperatures.

[0075] S103, and according to the target total cell group power increment and the actual start and stop status of each electrolytic cell group, determine the electrolytic cell group load change trend corresponding to the electrolytic cell cluster, the number of electrolytic cell groups in each operating state at the next moment, and the cell group power change rate.

[0076] The following steps are used to determine the load variation trend of the electrolytic cell group corresponding to the electrolytic cell cluster, the number of electrolytic cell groups in each operating state at the next moment, and the power variation rate of the cell group:

[0077] Step 1: If the target total cell group power increment is greater than or equal to 0, the load change trend of the electrolytic cell group corresponding to the electrolytic cell cluster is an increasing trend; if the target total cell group power increment is less than 0, the load change trend of the electrolytic cell group corresponding to the electrolytic cell cluster is a decreasing trend.

[0078] In the implementation mode of the present application, if the target total cell group power increment is greater than or equal to 0, it means that the electrolytic cell cluster needs to be loaded up to reach the total power of the electrolytic cell group planned by the upper layer, so the electrolytic cell group load change trend corresponding to the electrolytic cell cluster is a load increase trend. If the target total cell group power increment is less than 0, it means that the electrolytic cell cluster needs to be loaded down to reach the total power of the electrolytic cell group planned by the upper layer, so the electrolytic cell group load change trend corresponding to the electrolytic cell cluster is a load reduction trend.

[0079] Step 2: Calculate the cell group load-up power deviation and cell group load-down climbing power boundary corresponding to the electrolytic cell cluster according to the number of electrolytic cell groups whose actual start-stop state is the start state and the number of electrolytic cell groups whose actual start-stop state is the target working state.

[0080] In an embodiment of the present application, the product of the number of electrolytic cell groups whose actual start-stop state is the start state and the upper limit of the electrolytic cell group load-up climbing rate is determined as the cell group load-up power deviation Del_P1 corresponding to the electrolytic cell cluster; the product of the number of electrolytic cell groups whose actual start-stop state is the target working state and the upper limit of the electrolytic cell group load-down climbing rate is determined as the cell group load-down climbing power boundary Del_P2 corresponding to the electrolytic cell cluster; the upper limit of the electrolytic cell group load-up climbing rate and the upper limit of the electrolytic cell group load-down climbing rate are vectors, that is, the cell group load-up power deviation Del_P1 and the cell group load-down climbing power boundary Del_P2 are also vectors.

[0081] Step three, according to the load change trend of the electrolytic cell group corresponding to the electrolytic cell cluster and the numerical relationship among the target total cell group power increment, the cell group load increase power deviation and the cell group load reduction climbing power boundary, determine the number of electrolytic cell groups and the cell group power change rate in each operating state at the next moment corresponding to the electrolytic cell cluster.

[0082] In the implementation manner of the present application, the number of electrolytic cell groups in each operating state includes the number of electrolytic cell groups in the load-down state, the number of electrolytic cell groups in the static state, and the number of electrolytic cell groups in the dynamic state. The cell group power change rate refers to the cell group power change rate of the electrolytic cell group at the next moment.

[0083] Specifically, the number of electrolytic cell groups and the cell group power change rate of each operating state at the next moment corresponding to the electrolytic cell cluster are determined by the following steps:

[0084] (1) If the load change trend of the electrolytic cell group corresponding to the electrolytic cell cluster is a load increase trend, determine whether the cell group load reduction and climbing power boundary Del_P2 is less than or equal to the value obtained by subtracting the cell group load increase power deviation Del_P1 from the target total cell group power increment Del_P, and obtain a first judgment result.

[0085] (2) If the cell group load reduction and ramping power boundary Del_P2 is greater than the value obtained by subtracting the cell group load increase power deviation Del_P1 from the target total cell group power increment Del_P, it means that the target total cell group power increment exceeds the smoothing capacity of the electrolytic cell cluster. Then, the upper limit load reduction and ramping rate of the electrolytic cell group is determined as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the target working state; the value obtained by (Del_P-Del_P2) / the number of electrolytic cell groups whose actual start-stop state is the start state is determined as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the start state.

[0086] (3) If the cell group load reduction and ramping power boundary Del_P2 is less than or equal to the value obtained by subtracting the cell group load increase power deviation Del_P1 from the target total cell group power increment Del_P, it means that the target total cell group power increment is within the range of the electrolytic cell cluster's smoothing capability. Then, the electrolytic cell group upper limit load increase and ramping rate is determined as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the start state; the value obtained by (Del_P-Del_P1) / the number of electrolytic cell groups whose actual start-stop state is the target working state is determined as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the target working state;

[0087] (4) Determine the number of electrolytic cell groups in each operating state at the next moment based on the first judgment result and the actual start / stop status of each electrolytic cell group, so that the electrolytic cell cluster can operate according to the planned total power of the electrolytic cell group at the next moment.

[0088] (5) If the load change trend of the electrolytic cell group corresponding to the electrolytic cell cluster is a load reduction trend, the target total cell group power increment Del_P is deducted from the value of the cell group load reduction climbing power boundary Del_P1 to determine the target smoothing power Del_P3; and determine whether the cell group load increase power deviation Del_P1 is greater than the target total cell group power increment Del_P.

[0089] (6) If the cell group load power deviation Del_P1 is less than or equal to the target total cell group power increment Del_P, determine whether the cell group load power deviation Del_P1 is greater than the target smoothing power Del_P3; if the cell group load power deviation Del_P1 is greater than the target smoothing power Del_P3, it means that all electrolytic cell groups can meet the allocated power requirements when they are loaded. Then, according to the principle of taking the electrolytic cell group upper limit load ramp rate as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the start state, and the target smoothing power Del_P3 as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the target working state, the number of electrolytic cell groups in each operating state at the next moment and the cell group power change rate are determined according to the actual start-stop state of each electrolytic cell group, so that the electrolytic cell cluster can operate according to the planned total power of the electrolytic cell group at the next moment.

[0090] (7) If the cell group load power deviation Del_P1 is less than or equal to the target smoothing power Del_P3, it means that all electrolytic cell groups can meet the allocated power requirements when they are loaded, otherwise it means that all electrolytic cell groups cannot meet the allocated power requirements when they are loaded. In this case, according to the principle of taking the upper limit load ramp rate of the electrolytic cell group as the load ramp rate of all electrolytic cell groups, the number of electrolytic cell groups in each operating state and the cell group power change rate at the next moment are determined according to the actual start and stop status of each electrolytic cell group, so that the electrolytic cell cluster can operate according to the planned total power of the electrolytic cell group and the cell group power change rate at the next moment; the power beyond the smoothing capacity range is compensated by the battery charging and discharging power correction. If it still cannot be smoothed, the power beyond the smoothing capacity range is requested to be abandoned.

[0091] (8) If the cell group load-up power deviation Del_P1 is greater than the target total cell group power increment Del_P, determine whether the cell group load-down climbing power boundary Del_P2 is greater than the target smoothing power Del_P3, and obtain a second judgment result; if the cell group load-down climbing power boundary Del_P2 is greater than the target smoothing power Del_P3, it means that the target total cell group power increment exceeds the smoothing capacity of the electrolytic cell cluster, and the electrolytic cell group upper limit load-down climbing rate is determined as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the target working state; the value obtained by (Del_P-Del_P2) / the number of electrolytic cell groups whose actual start-stop state is the start state is determined as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the start state.

[0092] (9) If the cell group load reduction climbing power boundary Del_P2 is less than or equal to the target smoothing power Del_P3, it means that the target total cell group power increment is within the smoothing capacity of the electrolytic cell cluster, and the upper limit load reduction climbing rate of the electrolytic cell group is determined as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the shutdown state; when the electrolytic cell group whose actual start-stop state is the shutdown state is loaded down according to the upper limit load reduction climbing rate of the electrolytic cell group, the target smoothing power Del_P3 is determined as the cell group power change rate of the electrolytic cell group whose actual start-stop state is the target working state.

[0093] (10) Determine the number of electrolytic cell groups in each operating state at the next moment based on the second judgment result and the actual start / stop state of each electrolytic cell group, so that the electrolytic cell cluster can operate according to the planned total power of the electrolytic cell group at the next moment.

[0094] S104. Determine the target power corresponding to each electrolytic cell group according to the cell group power change rate, the target total cell group power increment, the actual start and stop status of each electrolytic cell group, the electrolytic cell group load change trend corresponding to the electrolytic cell cluster, and the number of electrolytic cell groups in each operating state at the next moment, so that each electrolytic cell group operates according to the corresponding target power.

[0095] Step 1: Determine the power change rate or target power of each electrolytic cell group at the next moment according to the power change rate of the cell group, the load change trend of the electrolytic cell group corresponding to the electrolytic cell cluster, the number of electrolytic cell groups in each operating state at the next moment, and the actual start and stop state of each electrolytic cell group.

[0096] (1) If the number of electrolytic cell groups in the load-down state at the next moment is greater than 0, and the load-change trend of the electrolytic cell groups is a load-down trend, the power change rate is preferentially allocated to the electrolytic cell groups whose actual start-stop state is the shutdown state according to the power change rate of the cell groups.

[0097] (2) If the number of electrolytic cell groups in the load-changing state at the next moment is greater than 0, and the load-changing trend of the electrolytic cell groups is an increasing trend, the power change rate is preferentially allocated to the electrolytic cell groups whose actual start-stop state is the start-up state according to the power change rate of the cell groups; if the number of electrolytic cell groups whose actual start-stop state is the start-up state is 0, the power change rate is preferentially allocated to the electrolytic cell groups with small actual operating power according to the power change rate of the cell groups.

[0098] (3) If the number of electrolytic cell groups in the static state at the next moment is greater than 0, determine whether the number of cell groups in the static state at the actual start / stop state is less than the number of electrolytic cell groups in the static state at the next moment; if the number of cell groups in the static state at the actual start / stop state is less than the number of electrolytic cell groups in the static state at the next moment, determine whether there is a moving cell group whose actual operating power is within a preset operating power threshold; if there is a target moving cell group whose actual operating power is within the preset operating power threshold, jump the target moving cell group within the preset operating power threshold to a static cell group, that is, determine the actual operating power of the target moving cell group as the target power of the target moving cell group.

[0099] The preset operating power threshold is [the planned power distribution of the electrolyzer group in the static state planned by the upper layer - the preset threshold, the planned power distribution of the electrolyzer group in the static state planned by the upper layer + the preset threshold]. The planned power distribution of the electrolyzer group in the static state planned by the upper layer is obtained by planning based on the wind power at the next moment, and refers to the power of the electrolyzer group in the static state planned by the upper layer at the next moment;

[0100] (4) If the number of electrolytic cell groups in the dynamic tank suppression state at the next moment is greater than 0, determine whether there is an electrolytic cell group whose actual start-stop state is the dynamic tank suppression state; if there is an electrolytic cell group whose actual start-stop state is the dynamic tank suppression state, the power change rate is preferentially allocated to the electrolytic cell group whose actual start-stop state is the dynamic tank suppression state according to the power change rate of the cell group.

[0101] (5) If there is no electrolytic cell group whose actual start-stop state is in the dynamic cell stabilization state, then when the electrolytic cell cluster has sufficient upper standby power to cope with random fluctuations, the power change rate is allocated to the electrolytic cell group whose actual start-stop state is in the load-increasing state and whose actual operating power is large, priority is given to allocating the power change rate according to the cell group power change rate; when the electrolytic cell cluster has sufficient lower standby power to cope with random fluctuations, the power change rate is allocated to the electrolytic cell group whose actual start-stop state is in the load-increasing state and whose actual operating power is small, priority is given to allocating the power change rate according to the cell group power change rate.

[0102] Step 2: for each electrolytic cell group whose power change rate at the next moment has been determined, the sum of the power change rate of each electrolytic cell group at the next moment and the target total cell group power increment is determined as the target power corresponding to each electrolytic cell group.

[0103] In an embodiment of the present application, for an electrolytic cell group assigned a power change rate, the sum of the power change rate of the electrolytic cell group at the next moment and the target total cell group power increment is determined as the target power corresponding to each electrolytic cell group.

[0104] The embodiment of the present application provides a control method for an electrolyzer cluster, the method comprising: according to the numerical relationship between the actual total power of the electrolyzer group and the operating boundary of the electrolyzer group, the planned operating number of the electrolyzer group and the actual start-stop state of each electrolyzer group, a start-stop state instruction is issued to the electrolyzer group in the electrolyzer cluster, so that the electrolyzer group operates according to the start-stop state instruction; and according to the target total tank group power increment and the actual start-stop state of each electrolyzer group, the electrolyzer group load change trend corresponding to the electrolyzer cluster, the number of electrolyzer groups in each operating state at the next moment, and the tank group power change rate are determined; according to the tank group power change rate, the target total tank group power increment, the actual start-stop state of each electrolyzer group, the electrolyzer group load change trend corresponding to the electrolyzer cluster and the number of electrolyzer groups in each operating state at the next moment, the target power corresponding to each electrolyzer group is determined, so that each electrolyzer group operates according to the corresponding target power. Through the method of the present application, the electrolyzer cluster can be reasonably controlled to achieve the stabilization of the random fluctuation power of wind power.

[0106] S201. Determine the target number of operating electrolytic cell groups of the electrolytic cell cluster at the next moment according to the numerical relationship between the actual total power of the electrolytic cell group and the operating boundary of the electrolytic cell group and the planned operating number of the electrolytic cell group.

[0107] S202, according to the actual start / stop status of each electrolytic cell group, the numerical relationship between the number of electrolytic cell groups whose actual start / stop status is in operation and the target number of electrolytic cell groups in operation, issuing start / stop status instructions to the electrolytic cell groups in the electrolytic cell cluster.
