[0031] The technical solution provided in the embodiments of the present invention is to solve the technical problems of insufficient dynamic response capability, low control balance and low economy in the prior art. The overall idea adopted is as follows: First, the array topology of the target capacitor array is obtained, and an array graph relationship network is constructed; then, the array state information of the target capacitor array is collected in real time, and the node state marks of multiple array nodes in the array graph relationship network are initialized according to the array state information; then, the control target of the target capacitor array is obtained, wherein the control target includes energy direction, energy capacity, and energy rate; then, according to the control target, the call constraint of the target capacitor array is defined, and according to the call constraint and the array graph relationship network, a random call decision of the target capacitor array is made to obtain an initial call strategy set; then, by calling a cost function, a cost evaluation of multiple initial call strategies in the initial call strategy set is performed, and the optimal selection is made according to the evaluation result to obtain the target call strategy; finally, the target call strategy is transmitted to the array control unit of the target capacitor array for common mode control.

[0032] The above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods of the specification to better understand the above technical solution. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments of the present invention. It should be understood that the present invention is not limited to the example embodiments used only to explain the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all of them.

[0033] Embodiment 1 Figure 1 The present invention is a flowchart of a common mode control method for a capacitor array, wherein the method comprises: The array topology relationship of the target capacitor array is obtained, and an array graph relationship network is constructed.

[0034] Specifically, the array topology relationship refers to the connection method and relative position between each unit in the capacitor array, including series connection, parallel connection and specific geometric arrangement. The topology data of the target capacitor array can be derived from the output of the actual circuit design file, schematic diagram or simulation software.

[0035] Exemplarily, the array topology relationship includes the position coordinates and arrangement pattern of each capacitor in the capacitor array; the endpoint connection relationship of each capacitor, such as whether adjacent capacitors are directly connected or connected to specific nodes through wires; and the parameters of each capacitor, such as capacitance value, withstand voltage value, etc.

[0036] Specifically, a graph structure is used to represent the topological relationship of the capacitor array. The nodes in the graph structure represent capacitor units, and the edges represent the connection relationship or wires between the capacitors. For example, each capacitor is defined as a node, and related attributes are stored in the node, such as capacitance value, physical location, connection node identifier, etc.; then, node edges are created to represent the connection relationship between the capacitor units.

[0037] The above process obtains the topological data of the capacitor array and uses graph relational network modeling to effectively represent and analyze the structure and behavior of the complex capacitor array.

[0038] In some embodiments, an array topology relationship of a target capacitor array is obtained, and an array graph relationship network is constructed, wherein the array graph relationship network includes a plurality of array nodes and a plurality of node edges, and the node edges are marked with edge weights based on connection path impedance.

[0039] Specifically, each node edge is marked with an edge weight, and the edge weight is determined based on the impedance of the array connection path corresponding to the node edge, indicating the difficulty of electric energy propagating on the path. Exemplarily, the edge weight is represented by an adjacency matrix, where the matrix element [i][j] represents the edge weight between node i and node j.

[0040] By calculating the path impedance and marking the edge weight, it provides efficient and intuitive information reference for subsequent performance analysis, control optimization and other operations.

[0041] The array state information of the target capacitor array is collected in real time, and the node state marks of multiple array nodes in the array graph relationship network are initialized according to the array state information.

[0042] Specifically, sensors or online monitoring equipment are used to obtain capacitor status data in real time and collect array status information, which may include capacitor operating status, health status, environmental parameters, connection status, etc.

[0043] Specifically, for each capacitor status information collected, the corresponding graph relationship network node is located, and the status information is updated to the node's status attribute. In other words, the node status mark of each array node is used to reflect the current status of the corresponding capacitor, such as working status, performance status, and connection status.

[0044] In some embodiments, real-time acquisition of array state information of the target capacitor array and initialization of node state marks of multiple array nodes in the array graph relationship network according to the array state information include: Interact with the target capacitor array to obtain capacitor status information of the plurality of capacitors, wherein the capacitor status information includes a capacitor characteristic curve and a capacitor SOC; and mark the node status marks of the plurality of array nodes according to a mapping relationship between the plurality of array nodes and the plurality of capacitors, wherein the node status marks include a capacity status mark, a voltage status mark and a current status mark.

[0045] Specifically, first, establish data interaction with the target capacitor array, and obtain the capacitor status information of each capacitor in real time through sensors, data acquisition modules (such as voltage and current sensors), and array management units. The capacitor status information includes the capacitor characteristic curve and capacitor SOC of the capacitor, wherein the capacitor characteristic curve involves the charging and discharging characteristics (such as voltage-current curve), capacity characteristics, aging characteristics, etc. of the capacitor; the capacitor SOC is used to indicate the current state of charge of the capacitor, expressed as a percentage of the capacity. For example, SOC=75% means that the current capacitance is 75% of the nominal capacity.

[0046] Specifically, in the array graph relationship network, each array node represents a capacitor unit, so according to the physical position or electrical connection relationship of the capacitor, a mapping from the capacitor to the array node is established, and the capacitor status information of each capacitor is updated to the status attribute of the corresponding node, and a node status mark is generated, including a capacity status mark reflecting the remaining capacity or health status of the capacitor corresponding to the node, a voltage status mark indicating the state of the voltage across the capacitor, and a current status mark describing the expected current maximum operating current of the capacitor.

[0047] By collecting capacitor status information in real time and mapping this information to node status tags in the array graph relationship network, the operation status of the capacitor array can be dynamically reflected, thereby providing basic data support for the status evaluation and control decision-making of the capacitor array.

[0048] A control target of a target capacitor array is obtained, wherein the control target includes energy direction, energy capacity, and energy rate.

[0049] Specifically, the control target of the target capacitor array refers to the desired power input or output task target of the target capacitor array, which is used to define the operating requirements and direction of the target capacitor array, such as the power compensation size, direction, capacity, etc. in the power compensation of the photovoltaic panel.

[0050] Specifically, energy direction is used to describe the direction of energy flow in the capacitor array, including energy input (charging), energy output (discharging), or both (some units charging, some units discharging); energy capacity specifies the total energy that needs to be stored or released by the target capacitor array; energy rate is the rate of energy transfer of the capacitor array (i.e., charging and discharging power).

[0051] According to the control target, the call constraints of the target capacitor array are defined, and according to the call constraints and the array graph relationship network, a random call decision of the target capacitor array is performed to obtain an initial call strategy set.

[0052] Specifically, based on the control objectives, the call constraints of the target capacitor array are defined to ensure that the initial call strategies obtained all meet the control objectives of the target capacitor array, wherein the call constraints include energy direction constraints, energy capacity constraints, and energy rate constraints. The energy direction constraints are used to ensure that the capacitors corresponding to the initial call strategies have energy flow directions that meet the control objectives, the energy capacity constraints are used to ensure that the capacitors corresponding to the initial call strategies can provide sufficient energy storage / release capacity, and the energy rate constraints are used to ensure that the energy storage / release efficiency of the capacitors corresponding to the initial call strategies meet the control objectives.

[0053] In some embodiments, according to the control target, a call constraint of the target capacitor array is defined, and according to the call constraint and the array graph relationship network, a random call decision of the target capacitor array is made to obtain an initial call strategy set, including: The array graph relationship network is used as a selection space to randomly select the array nodes, and multiple capacitor combinations are obtained based on the selection results; combined performance data of multiple capacitor combinations are calculated according to the node status marks in combination with the physical property program, and the combined performance data includes performance direction, performance capacity, and performance rate; the combined performance data is compared with the call constraint, and if the performance direction, the performance capacity, and the performance rate all satisfy the performance direction, the performance capacity, and the performance rate, the corresponding capacitor combination is stored in the initial call strategy set.

[0054] Specifically, first, the array graph relationship network is used as the selection space to randomly select array nodes, that is, the capacitor array is regarded as a sample space, and nodes (i.e., capacitors) therein are randomly selected to obtain multiple capacitor combinations; then, combined with the physical property program, the combined performance data of each capacitor combination is calculated according to the node status mark, including the performance direction (referring to the direction of current), the performance capacity (referring to the charge capacity of the capacitor) and the performance rate (referring to the transfer rate of charge), wherein the physical property program is software or algorithm used to simulate the performance of capacitor combinations according to the node status mark.

[0055] Furthermore, the calculated combined efficiency data is compared with the previously defined call constraints. When the efficiency direction, efficiency capacity and efficiency rate all meet the constraints, it can be considered that the energy storage / release performance of the corresponding capacitor combination meets the requirements of the control target, and the corresponding capacitor combination is used as an initial call strategy and stored in the initial call strategy set.

[0056] Through the above process, we can preliminarily obtain multiple calling strategies that meet the basic performance requirements of the control target, thereby providing a basis for subsequent optimization selection.

[0057] By calling the cost function, a cost evaluation is performed on multiple initial call strategies in the initial call strategy set, and the optimal selection is performed according to the evaluation result to obtain the target call strategy.

[0058] Specifically, the call cost function is used to evaluate the control costs of multiple initial call strategies based on information such as the capacitor state, capacitor location distribution, and capacitor connection paths of the capacitor combinations of multiple initial call strategies in the initial call strategy set. For example, the greater the path loss corresponding to the initial call strategy, the greater the life consumption of the capacitor, and the more capacitors that need to be called, the greater the corresponding call cost function value.

[0059] In some embodiments, by calling the cost function, performing a cost evaluation of multiple initial call strategies in the initial call strategy set, and performing an optimal selection based on the evaluation result to obtain a target call strategy, including: Construct the call cost function, wherein the call cost function includes a path loss factor and a call scale factor; calculate the call cost values ​​of multiple initial call strategies according to the call cost function, and arrange the call cost values ​​in ascending order to obtain a call cost sequence; based on the call cost sequence, select the initial call strategy corresponding to the call cost value at the first position in the sequence, and output it as the target call strategy.

[0060] Specifically, first, a call cost function is constructed, which includes a path loss factor and a call scale factor, wherein the path loss factor is used to quantify the transmission loss of electric energy in the capacitor array according to the weights of the edges in the array graph relationship network, and the call scale factor refers to the number or scale of the called capacitors; then, according to the call cost function, the call cost value of each initial call strategy in the initial call strategy set is calculated, and the call cost value is a number that quantifies the cost or loss of executing the strategy.

[0061] Furthermore, the calculated call cost values ​​are arranged in ascending order to obtain a call cost sequence. In the call cost sequence, the smaller the value, the lower the cost of the strategy. In other words, the strategies at the front of the call cost sequence have higher execution efficiency and smaller losses. Then, the strategy at the first position (i.e., with the lowest cost) in the call cost sequence is selected as the target call strategy. This strategy is the optimal strategy among all the initial call strategies.

[0062] The target calling strategy is transmitted to an array control unit of a target capacitor array for common mode control.

[0063] Specifically, the target call strategy is first encoded or encapsulated into a format that can be transmitted through a communication interface, such as JSON, XML or binary format; then, the encapsulated target call strategy is transmitted to the array control unit through the communication interface and a standard communication protocol, such as TCP / IP, RS-485 or CAN. After receiving the target call strategy, the array control unit parses or decodes the strategy and converts it into an executable instruction call capacitor.

[0064] In some embodiments, the method further comprises: The cumulative call times of multiple capacitors in the target capacitor array are recorded by an accumulator; the cumulative call depths of multiple capacitors in the target capacitor array are obtained by statistically analyzing the historical control records; and the call weights of multiple capacitors in the target capacitor array are updated in combination with the cumulative call times and the cumulative call depths, wherein the initial values ​​of the call weights of the multiple capacitors are consistent.

[0065] Specifically, first, the cumulative number of calls of each capacitor in the target capacitor array is recorded through an accumulator, that is, each time a capacitor is called, the corresponding cumulative number of calls of the capacitor increases once, and then, the cumulative call depth of each capacitor in the target capacitor array is obtained by statistically analyzing the historical control records. The call depth can be understood as the degree to which the capacitor is used each time it is called, such as the charge consumption or working time of the capacitor. Preferably, the call depth is expressed as the number of cycles of energy storage / release of the capacitor.

[0066] Furthermore, the call weight of each capacitor in the target capacitor array is updated in combination with the cumulative number of calls and the cumulative call depth. For example, the larger the cumulative number of calls and the cumulative call depth, the more frequently the corresponding capacitor is used and the higher the intensity of use, and the call weight of the capacitor is correspondingly reduced.

[0067] Specifically, when the target capacitor array is started, the initial values ​​of the calling weights of all capacitors are consistent, that is, all capacitors have the same probability of being called at the beginning.

[0068] The call weight of the capacitor is updated by tracking and counting the cumulative call times and cumulative call depth of the capacitor to better balance the use of the capacitor and avoid overuse of some capacitors, thereby extending the life of the entire array.

[0069] In some embodiments, the method further comprises: Based on the target call strategy, the call weight is updated; the updated call weight is normalized, and based on the normalization result, the equivalent call probability of multiple capacitors is calculated to obtain an equivalent call probability set; according to the equivalent call probability set, the corresponding information entropy is calculated and output as a balance index for obtaining the target call strategy; if the balance index is less than or equal to a preset balance control limit, a random call decision is iterated until the new target call strategy obtained is greater than the balance control limit.

[0070] Specifically, first, based on the target calling strategy, the calling weights of the capacitors are updated, that is, the target calling strategy is regarded as the applied calling strategy, and the calling weights of multiple capacitors after the target calling strategy is applied are obtained; then, the updated calling weights are normalized so that the sum of the calling weights of all capacitors is 1, thereby converting the calling weights of multiple capacitors into equivalent calling probabilities, and obtaining an equivalent calling probability set.

[0071] Furthermore, according to the equivalent call probability set, the corresponding information entropy is calculated as the balance index of the target call strategy, wherein the information entropy can be used to measure the distribution balance of the calls to the capacitors in the target capacitor array. The larger the value of the information entropy, the more balanced the distribution of the equivalent call probability, and it can be considered that the calls to the target capacitor array are more balanced.

[0072] Specifically, if the balance index is less than or equal to the preset balance control limit, there is a call imbalance in the target capacitor array, and it is necessary to iterate the random call decision, re-acquire multiple initial call strategies, and make the best selection based on the above-mentioned optimization process until the balance index corresponding to the new target call strategy obtained is greater than the balance control limit.

[0073] The above method steps further quantitatively evaluate the balance of the target call strategy by introducing a balance index based on information entropy. If the balance index is lower than the preset balance control limit, the target call strategy is optimized by iterative random call decisions until its balance index reaches the preset limit, thereby ensuring the balanced use of the capacitor array and improving the stability and reliability of the capacitor array.

[0074] In summary, the common-mode control method for a capacitor array provided by the present invention has the following technical effects: By acquiring the array topology of the target capacitor array, the corresponding array graph relationship network is constructed; the state information of the target capacitor array is collected in real time, and the state mark of each array node in the array graph relationship network is initialized based on the collection result; the control target of the target capacitor array is obtained, and the control target includes energy direction, energy capacity and energy rate; the call constraint of the target capacitor array is defined according to the control target, and the call constraint and the array graph relationship network are combined to perform random call decision and generate an initial call strategy set; the call cost function is used to evaluate the cost of multiple strategies in the initial call strategy set, and the optimal strategy is selected based on the evaluation result to generate the target call strategy; the target call strategy is transmitted to the control unit of the target capacitor array to implement common mode control. Thus, the technical effect of improving control responsiveness, improving control balance and economy is achieved.
