[0074] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0075] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant regulations.

[0076] At present, the pumped storage units are managed and controlled by dispatching system A and dispatching system B. These two dispatching systems will increase or decrease the load and capacity of the pumped storage units according to the load requirements of their respective power grids. Therefore, the load transfer function is often used between the two dispatching systems to transfer the load of the pumped storage units to achieve the role of load regulation and balance of their respective power grids. Due to the limitations of the communication protocol, the various analog set values ​​issued by dispatching system A and dispatching system B will have a deviation of 0.01 to 0.02. The load transfer module in the original host computer control program did not take into account the slight error caused by the data format conversion during the communication process, which may cause deviations from the calculation results of the subsequent execution value assignment module. The possible results are: when the load transfer is set by the dispatcher, it is possible that the capacity and load setting values ​​of one party's dispatch are judged by the load transfer module and sent to the subsequent execution value assignment module for execution, while the setting values ​​of the other party are judged by the load transfer module but cannot be judged by the subsequent execution value assignment module, and the setting values ​​before the transfer are maintained, so that the two dispatching capacities and loads actually executed are greater than or less than the dispatching setting values, which may cause the unit to start or stop extra. The most serious consequence is that the pumped-storage unit is completely shut down for power generation or pumping, which will cause a large amount of load shortage to the power grid. In order to ensure the operating stability of the power grid system where the pumped-storage unit is located, it is very important to accurately transfer the load of the pumped-storage unit. However, in the process of load transfer of the pumped-storage unit, manual adjustment is generally adopted; however, this manual adjustment method has subjective factors and is prone to errors, resulting in low accuracy of load transfer of the pumped-storage unit. Therefore, the present application provides a method for load transfer of pumped-storage units, which can solve the problem of low accuracy of load transfer of pumped-storage units and achieve the effect of improving the accuracy of load transfer of pumped-storage units.

[0077] In an exemplary embodiment, Figure 1 As shown, a method for load transfer of a pumped storage unit is provided. This embodiment uses the method applied to a server as an example for illustration; it can be understood that the method can also be applied to a terminal, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. Among them, the terminal can be but is not limited to various personal computers, laptops, smart phones and tablets; the server can be implemented with an independent server or a server cluster composed of multiple servers. In this embodiment, the method includes the following steps:

[0078] Step S101, obtaining a first load setting value, a first capacity setting value, a second load setting value, a second capacity setting value, a first load execution value, a first capacity execution value, a second load execution value and a second capacity execution value of the pumped-storage unit to be analyzed.

[0079] Among them, the pumped-storage unit to be analyzed refers to the pumped-storage unit that needs to be loaded with load transfer.

[0080] Among them, the first load setting value refers to the load setting value of the pumped-storage unit to be analyzed set by the dispatching system A.

[0081] Among them, the first capacity setting value refers to the capacity setting value of the pumped-storage unit to be analyzed set by the dispatching system A.

[0082] Among them, the second load setting value refers to the load setting value of the pumped-storage unit to be analyzed set by the dispatching system B.

[0083] Among them, the second capacity setting value refers to the capacity setting value of the pumped-storage unit to be analyzed set by the dispatching system B.

[0084] Among them, the first load execution value refers to the load execution value of the pumped-storage unit to be analyzed set by the dispatching system A.

[0085] Among them, the first capacity execution value refers to the capacity execution value of the pumped-storage unit to be analyzed set by the dispatching system A.

[0086] Among them, the second load execution value refers to the load execution value of the pumped-storage unit to be analyzed set by the dispatching system B.

[0087] Among them, the second capacity execution value refers to the capacity execution value of the pumped-storage unit to be analyzed set by the dispatching system B.

[0088] Exemplarily, the server determines, from multiple candidate scheduling systems, a candidate scheduling system corresponding to the pumped-storage unit to be analyzed as a target scheduling system (such as scheduling system A and scheduling system B); then, the server obtains the first load setting value, the first capacity setting value, the second load setting value, the second capacity setting value, the first load execution value, the first capacity execution value, the second load execution value and the second capacity execution value of the pumped-storage unit to be analyzed through the target scheduling system.

[0089] Step S102, obtaining a first difference value according to the first capacity setting value, the second capacity setting value, the first capacity execution value, and the second capacity execution value, and obtaining a second difference value according to the first load setting value, the second load setting value, the first load execution value, and the second load execution value.

[0090] The first difference is used to represent the difference between the capacity setting value and the capacity execution value of the pumped-storage unit to be analyzed.

[0091] The second difference is used to represent the difference between the load setting value and the load execution value of the pumped-storage unit to be analyzed.

[0092] Exemplarily, the server constructs a first correspondence between the first capacity setting value, the second capacity setting value, the first capacity execution value, the second capacity execution value and the first difference, and constructs a correspondence between the first load setting value, the second load setting value, the first load execution value, the second load execution value and the second difference; then, the server queries the first correspondence based on the first capacity setting value, the second capacity setting value, the first capacity execution value, the second capacity execution value to obtain the first difference; then, the server queries the second correspondence based on the first load setting value, the second load setting value, the first load execution value and the second load execution value to obtain the second difference.

[0093] Step S103, updating the first capacity setting value and the second capacity setting value respectively according to the first difference, to obtain a first updated capacity setting value and a second updated capacity setting value of the pumped storage unit to be analyzed.

[0094] The first updated capacity setting value is used to represent the adjusted first capacity setting value of the pumped-storage unit to be analyzed.

[0095] The second updated capacity setting value is used to represent the adjusted second capacity setting value of the pumped-storage unit to be analyzed.

[0096] Exemplarily, the server updates the first capacity setting value based on the first difference to obtain a first updated capacity setting value of the pumped-storage unit to be analyzed; then, the server updates the second capacity setting value based on the first difference to obtain a second updated capacity setting value of the pumped-storage unit to be analyzed.

[0097] For example, the server may obtain the first updated capacity setting value through the following formula:

[0098] QCOG ' = QCOG + DIFF1*QCOG / (QCOG-QCOC), formula (1)

[0099] Wherein, QCOG ′ refers to the first updated capacity setting value, QCOG refers to the first capacity setting value, QCOC refers to the second capacity setting value, and DIFF1 refers to the first difference value.

[0100] For example, the server can obtain the second updated capacity setting value through the following formula:

[0101] QCOC ' = QCOC + DIFF1* QCOC / (QCOG-QCOC), formula (2)

[0102] Wherein, QCOC ' refers to the second updated capacity setting value.

[0103] Step S104, updating the first load setting value and the second load setting value respectively according to the second difference, to obtain a first updated load setting value and a second updated load setting value of the pumped storage unit to be analyzed.

[0104] The first updated load setting value is used to represent the adjusted first load setting value of the pumped-storage unit to be analyzed.

[0105] The second updated load setting value is used to represent the adjusted second load setting value of the pumped-storage unit to be analyzed.

[0106] Exemplarily, the server updates the first load setting value according to the second difference to obtain a first updated load setting value of the pumped-storage unit to be analyzed; then, the server updates the second load setting value according to the second difference to obtain a second updated load setting value of the pumped-storage unit to be analyzed.

[0107] For example, the server can obtain the first updated load setting value through the following formula:

[0108] QLOG ' = QLOG + DIFF2*QLOG / (QLOG-QLOC), equation (3)

[0109] Wherein, QLOG ' refers to the first updated load setting value, QLOG refers to the first load setting value, QLOC refers to the second load setting value, and DIFF2 refers to the second difference value.

[0110] For example, the server can obtain the second updated load setting value through the following formula:

[0111] QLOC ' = QLOC + DIFF2*QLOC / (QLOG-QLOC), equation (4)

[0112] Wherein, QLOC ' refers to the second updated load setting value.

[0113] Step S105, inputting the first updated capacity setting value, the second updated capacity setting value, the first updated load setting value and the second updated load setting value into a pre-trained load transfer instruction prediction model to obtain a target load transfer instruction corresponding to the pumped-storage unit to be analyzed.

[0114] Among them, the load transfer instruction prediction model refers to a network model that can use the first updated capacity setting value, the second updated capacity setting value, the first updated load setting value and the second updated load setting value of the pumped-storage unit to be analyzed to obtain the target load transfer instruction corresponding to the pumped-storage unit to be analyzed, such as a long short-term memory network model.

[0115] The target load transfer instruction refers to instruction information for load transfer processing of the pumped storage unit to be analyzed.

[0116] Exemplarily, the server preprocesses the first updated capacity setting value, the second updated capacity setting value, the first updated load setting value, and the second updated load setting value, respectively, to obtain the first preprocessed capacity setting value, the second preprocessed capacity setting value, the first preprocessed load setting value, and the second preprocessed load setting value of the pumped-storage unit to be analyzed; then, the server inputs the first preprocessed capacity setting value, the second preprocessed capacity setting value, the first preprocessed load setting value, and the second preprocessed load setting value into a pre-trained load transfer instruction prediction model to obtain the target load transfer instruction corresponding to the pumped-storage unit to be analyzed.

[0117] Step S106: performing corresponding load transfer processing on the pumped storage unit to be analyzed according to the target load transfer instruction.

[0118] Exemplarily, the server performs integrity verification on the target load transfer instruction and obtains a verification result corresponding to the target load transfer instruction; when the verification result indicates that the target load transfer instruction is passed, the server performs corresponding load transfer processing on the pumped-storage unit to be analyzed according to the target load transfer instruction.

[0119] In the above-mentioned pumped storage unit load transfer method, the first load setting value, the first capacity setting value, the second load setting value, the second capacity setting value, the first load execution value, the first capacity execution value, the second load execution value and the second capacity execution value of the pumped storage unit to be analyzed are first obtained, and the first difference is obtained according to the first capacity setting value, the second capacity setting value, the first capacity execution value and the second capacity execution value, and the second difference is obtained according to the first load setting value, the second load setting value, the first load execution value and the second load execution value, and then the first capacity setting value and the second capacity setting value are respectively updated according to the first difference to obtain the pumped storage unit to be analyzed. The first updated capacity setting value and the second updated capacity setting value of the unit are obtained, and then, according to the second difference, the first load setting value and the second load setting value are updated respectively to obtain the first updated load setting value and the second updated load setting value of the pumped-storage unit to be analyzed, and then, the first updated capacity setting value, the second updated capacity setting value, the first updated load setting value and the second updated load setting value are input into the pre-trained load transfer instruction prediction model to obtain the target load transfer instruction corresponding to the pumped-storage unit to be analyzed, and finally, according to the target load transfer instruction, the corresponding load transfer processing is performed on the pumped-storage unit to be analyzed. In this way, in the process of load transfer for pumped-storage units, by obtaining multi-dimensional data associated with different aspects of the pumped-storage units to be analyzed, and through a series of processing such as difference processing, update processing, and model processing, it is avoided to rely solely on single data for judgment, so that more accurate load transfer instructions for the pumped-storage units to be analyzed can be obtained, and then the corresponding load transfer processing can be performed more accurately on the pumped-storage units to be analyzed, which is beneficial to improving the load transfer accuracy of the pumped-storage units; moreover, the entire process does not require human intervention, avoiding the subjective factors in the manual adjustment method, which is prone to errors and leads to the defect of low load transfer accuracy of the pumped-storage units, thereby improving the load transfer accuracy of the pumped-storage units.

[0120] In an exemplary embodiment, the above step S105, inputting the first updated capacity setting value, the second updated capacity setting value, the first updated load setting value, and the second updated load setting value into a pre-trained load transfer instruction prediction model to obtain a target load transfer instruction corresponding to the pumped storage unit to be analyzed, specifically includes the following steps:

[0121] Step S201, input the first updated capacity setting value, the second updated capacity setting value, the first updated load setting value and the second updated load setting value into a pre-trained load transfer instruction prediction model to obtain multiple predicted load transfer instructions corresponding to the pumped-storage unit to be analyzed, and the predicted probability of each predicted load transfer instruction.

[0122] Step S202 , selecting the predicted load transfer instruction with the largest predicted probability from each predicted load transfer instruction as the target load transfer instruction.

[0123] The predicted load transfer instruction is used to indicate the predicted instruction corresponding to the load transfer processing of the pumped storage unit to be analyzed.

[0124] The prediction probability is used to indicate the possibility that the load transfer instruction prediction model determines that the predicted load transfer instruction is correct.

[0125] Exemplarily, the server uses the first updated capacity setting value as the main data, and the second updated capacity setting value, the first updated load setting value, and the second updated load setting value as auxiliary data, and inputs them into the feature extraction model for feature extraction processing to obtain a first feature vector corresponding to the first updated capacity setting value; then, the server uses the second updated capacity setting value as the main data, and the first updated capacity setting value, the first updated load setting value, and the second updated load setting value as auxiliary data, and inputs them into the feature extraction model for feature extraction processing to obtain a second feature vector corresponding to the second updated capacity setting value; then, the server uses the first updated load setting value as the main data, and the first updated capacity setting value, the second updated capacity setting value, and the second updated load setting value as auxiliary data, and inputs them into the feature extraction model for feature extraction processing to obtain a first The server then uses the second updated load setting value as the main data, and the first updated capacity setting value, the second updated capacity setting value and the first updated load setting value as auxiliary data, and inputs them into the feature extraction model for feature extraction processing to obtain the fourth feature vector corresponding to the second updated load setting value; then, the server inputs the first feature vector, the second feature vector, the third feature vector and the fourth feature vector into the pre-trained load transfer instruction prediction model, and obtains multiple predicted load transfer instructions corresponding to the pumped-storage unit to be analyzed, and the predicted probability of each predicted load transfer instruction through the pre-trained load transfer instruction prediction model; finally, the server selects the predicted load transfer instruction with the largest predicted probability from each predicted load transfer instruction, and uses the predicted load transfer instruction as the target load transfer instruction.

[0126] In this embodiment, the predicted load transfer instruction with the highest predicted probability is screened out as the target load transfer instruction, so as to ensure that the selected instruction is highly consistent with the actual current situation of the unit, thereby making the unit smoother and more efficient when performing load transfer operations, avoiding problems such as equipment loss and unstable operation due to unreasonable instructions.

[0127] In an exemplary embodiment, the above step S102 obtains a first difference value according to the first capacity setting value, the second capacity setting value, the first capacity execution value, and the second capacity execution value, and specifically includes the following contents: weighting the first capacity setting value and the second capacity setting value to obtain a weighted capacity setting value, and weighting the first capacity execution value and the second capacity execution value to obtain a weighted capacity execution value; performing a difference processing on the weighted capacity setting value and the weighted capacity execution value to obtain the first difference value.

[0128] According to the first load setting value, the second load setting value, the first load execution value and the second load execution value, a second difference is obtained, which specifically includes the following contents: weighting the first load setting value and the second load setting value to obtain a weighted load setting value, and weighting the first load execution value and the second load execution value to obtain a weighted load execution value; performing difference processing on the weighted load setting value and the weighted load execution value to obtain the second difference.

[0129] The weighted capacity setting value refers to a capacity setting value obtained by weighting the first capacity setting value and the second capacity setting value.

[0130] The weighted capacity execution value refers to a capacity execution value obtained by weighting the first capacity execution value and the second capacity execution value.

[0131] The weighted load setting value refers to a load setting value obtained by weighting the first load setting value and the second load setting value.

[0132] The weighted load execution value refers to a load execution value obtained by weighting the first load execution value and the second load execution value.

[0133] Exemplarily, the server performs weighted processing on the first capacity setting value and the second capacity setting value to obtain the weighted capacity setting value as the weighted capacity setting value, and performs weighted processing on the first capacity execution value and the second capacity execution value to obtain the weighted capacity execution value as the weighted capacity execution value; then, the server performs difference processing on the weighted capacity setting value and the weighted capacity execution value to obtain the difference between the weighted capacity setting value and the weighted capacity execution value as the first difference; then, the server performs weighted processing on the first load setting value and the second load setting value to obtain the weighted load setting value as the weighted load setting value, and performs weighted processing on the first load execution value and the second load execution value to obtain the weighted load execution value as the weighted load execution value; then, the server performs difference processing on the weighted load setting value and the weighted load execution value to obtain the difference between the weighted load setting value and the weighted load execution value as the second difference.

[0134] For example, the server can obtain the weighted capacity setting value through the following formula:

[0135] CAPAO = QCOG + QCOC, formula (5)

[0136] Among them, CAPAO refers to the weighted capacity setting value.

[0137] For example, the server can obtain the weighted capacity execution value through the following formula:

[0138] CAPAE = QCEG + QCEC, formula (6)

[0139] Among them, CAPAE refers to the weighted capacity execution value, QCEG refers to the first capacity execution value, and QCEC refers to the second capacity execution value.

[0140] For example, the server may obtain the first difference through the following formula:

[0141] DIFF1=CAPAE – CAPAO, equation (7)

[0142] For example, the server can obtain the weighted load setting value through the following formula:

[0143] LOADO=QLOG+QLOC, formula (8)

[0144] Among them, LOADO refers to the weighted load setting value.

[0145] For example, the server can obtain the weighted load execution value through the following formula:

[0146] LOADE = QLEG + QLEC, formula (9)

[0147] Among them, LOADE refers to the weighted load execution value, QLEG refers to the first load execution value, and QLEC refers to the second load execution value.

[0148] For example, the server may obtain the second difference value by the following formula:

[0149] DIFF2=LOADO – LOADE, formula (10)

[0150] In this embodiment, the first difference and the second difference can be quickly and directly obtained through multiple data associated with the pumped-storage unit to be analyzed. The entire process does not require human intervention, avoiding the need for manual calculation that easily consumes a lot of time and manpower, which is conducive to improving the efficiency of determining the first difference and the second difference.

[0151] In an exemplary embodiment, the above step S102, after obtaining the first difference according to the first capacity setting value, the second capacity setting value, the first capacity execution value, and the second capacity execution value, and obtaining the second difference according to the first load setting value, the second load setting value, the first load execution value, and the second load execution value, specifically includes the following contents: obtaining the capacity setting value tolerance rate and the load setting value tolerance rate of the pumped-storage unit to be analyzed.

[0152] Then, according to the first difference, the first capacity setting value and the second capacity setting value are updated respectively to obtain the first updated capacity setting value and the second updated capacity setting value of the pumped-storage unit to be analyzed, which specifically includes the following contents: when the first difference is less than the capacity setting value tolerance rate, according to the first difference, the first capacity setting value and the second capacity setting value are updated respectively to obtain the first updated capacity setting value and the second updated capacity setting value of the pumped-storage unit to be analyzed.

[0153] Then, according to the second difference, the first load setting value and the second load setting value are updated respectively to obtain the first updated load setting value and the second updated load setting value of the pumped-storage unit to be analyzed, which specifically includes the following contents: when the second difference is less than the load setting value tolerance rate, according to the second difference, the first load setting value and the second load setting value are updated respectively to obtain the first updated load setting value and the second updated load setting value of the pumped-storage unit to be analyzed.

[0154] The capacity setting value error tolerance rate is used to indicate the range ratio of the capacity setting value error.

[0155] The load setting value error tolerance rate is used to indicate the range ratio of the load setting value error.

[0156] Exemplarily, the server determines the capacity setting value fault tolerance rate and the load setting value fault tolerance rate of the pumped-storage unit to be analyzed based on the manually set fault tolerance rate parameters; then, the server judges the first difference based on the capacity setting value fault tolerance rate; when the first difference is less than the capacity setting value fault tolerance rate, the server updates the first capacity setting value based on the first difference to obtain the first updated capacity setting value of the pumped-storage unit to be analyzed, and updates the second capacity setting value based on the first difference to obtain the second updated capacity setting value of the pumped-storage unit to be analyzed; when the first difference is greater than or equal to the capacity setting value fault tolerance rate, the server generates early warning information for the pumped-storage unit to be analyzed, and sends The warning information is sent to the target terminal associated with the pumped-storage unit to be analyzed; then, the server judges the second difference according to the load setting value tolerance rate; when the second difference is less than the load setting value tolerance rate, the server updates the first load setting value according to the second difference to obtain the first updated load setting value of the pumped-storage unit to be analyzed, and updates the second load setting value according to the second difference to obtain the second updated load setting value of the pumped-storage unit to be analyzed; when the second difference is greater than or equal to the load setting value tolerance rate, the server generates warning information for the pumped-storage unit to be analyzed, and sends the warning information to the target terminal associated with the pumped-storage unit to be analyzed.

[0157] In this embodiment, by obtaining the capacity setting value tolerance rate and the load setting value tolerance rate, a reasonable allowable error range is set for the capacity and load parameters of the pumped-storage unit during operation, thereby avoiding frequent and unnecessary changes in the set values ​​due to excessive sensitivity to small deviations, thereby ensuring that the pumped-storage unit can continue to operate in a relatively stable state.

[0158] In an exemplary embodiment, the above-mentioned step S101, after obtaining the first load setting value, the first capacity setting value, the second load setting value, the second capacity setting value, the first load execution value, the first capacity execution value, the second load execution value and the second capacity execution value of the pumped-storage unit to be analyzed, specifically includes the following contents: verifying the first load setting value, the first capacity setting value, the second load setting value and the second capacity setting value to obtain a verification result; when the verification result meets a preset condition, generating early warning information of the pumped-storage unit to be analyzed; and sending the early warning information to the target terminal associated with the pumped-storage unit to be analyzed.

[0159] The verification result is used to indicate the verification status corresponding to the first load setting value, the first capacity setting value, the second load setting value and the second capacity setting value.

[0160] The preset condition refers to a pre-set judgment condition used to judge the verification result. For example, the absolute value of the first load setting value is less than or equal to the absolute value of the first capacity setting value, or the absolute value of the second load setting value is less than or equal to the absolute value of the second capacity setting value, or the first load setting value and the first capacity setting value have opposite signs, or the second load setting value and the second capacity setting value have opposite signs. It should be noted that the preset condition depends on the circumstances.

[0161] Among them, the early warning information is used to indicate that the pumped storage unit to be analyzed is abnormal.

[0162] The target terminal refers to the terminal associated with the pumped storage unit to be analyzed.

[0163] Exemplarily, the server verifies the first load setting value, the first capacity setting value, the second load setting value and the second capacity setting value according to their respective corresponding absolute values ​​and signs, to obtain a verification result; when the verification result meets a preset condition, the server generates early warning information of the pumped-storage unit to be analyzed according to the unit identification of the pumped-storage unit to be analyzed; then, the server determines the target terminal associated with the pumped-storage unit to be analyzed, and sends the early warning information to the target terminal through the network path between the server and the target terminal.

[0164] In this embodiment, by verifying the key parameters such as the first load setting value, the first capacity setting value, the second load setting value and the second capacity setting value, the rationality and accuracy of the load and capacity settings of the pumped-storage unit can be comprehensively checked, so that the pumped-storage unit can maintain a stable and reliable operating state.

[0182] The actual load transfer instruction corresponding to the sample pumped-storage unit is used to indicate the actual instruction corresponding to the load transfer processing for the sample pumped-storage unit.

[0183] Exemplarily, in response to a model training instruction for a load transfer instruction prediction model to be trained, the server obtains from a database a first sample load setting value, a first sample capacity setting value, a second sample load setting value, a second sample capacity setting value, a first sample load execution value, a first sample capacity execution value, a second sample load execution value, and a second sample capacity execution value of a sample pumped-storage unit; then, the server obtains a first sample difference value according to the first sample capacity setting value, the second sample capacity setting value, the first sample capacity execution value, and the second sample capacity execution value, and obtains a second sample difference value according to the first sample load setting value, the second sample load setting value, the first sample load execution value, and the second sample load execution value; then, the server updates the first sample capacity setting value and the second sample capacity setting value according to the first sample difference value, respectively, to obtain a first updated sample capacity setting value and a second updated sample capacity setting value of the sample pumped-storage unit; then, the server updates the first sample load setting value and the second sample capacity setting value according to the second sample difference value, respectively.

[0196] Step S311, according to the target load transfer instruction, corresponding load transfer processing is performed on the pumped storage unit to be analyzed.

[0197] In the above-mentioned load transfer method for pumped-storage units, in the process of load transfer to the pumped-storage units, by obtaining multi-dimensional data associated with different aspects of the pumped-storage units to be analyzed, and through a series of processing such as difference processing, update processing, and model processing, it is avoided to rely solely on a single data for judgment, so that a more accurate load transfer instruction for the pumped-storage units to be analyzed can be obtained, and then the corresponding load transfer processing can be more accurately performed on the pumped-storage units to be analyzed, which is beneficial to improving the load transfer accuracy of the pumped-storage units; moreover, the entire process does not require human intervention, avoiding the subjective factors in the manual adjustment method, which is prone to errors and leads to the defect of low load transfer accuracy of the pumped-storage units, thereby improving the load transfer accuracy of the pumped-storage units.

[0198] In an exemplary embodiment, in order to more clearly illustrate the load transfer method of the pumped storage unit provided in the embodiment of the present application, the load transfer method of the pumped storage unit is specifically described below with a specific embodiment. In one embodiment, Figure 4 As shown, the present application also provides a control method for a pumped storage unit. In the process of load transfer of the pumped storage unit, the first load setting value, the first capacity setting value, the second load setting value, the second capacity setting value, the first load execution value, the first capacity execution value, the second load execution value and the second capacity execution value of the pumped storage unit to be analyzed are first obtained, and a first difference is obtained according to the first capacity setting value, the second capacity setting value, the first capacity execution value and the second capacity execution value, and a second difference is obtained according to the first load setting value, the second load setting value, the first load execution value and the second load execution value, and then the first capacity setting value and the second capacity setting value are respectively controlled according to the first difference. Update processing is performed to obtain the first updated capacity setting value and the second updated capacity setting value of the pumped storage unit to be analyzed. Then, according to the second difference, the first load setting value and the second load setting value are respectively updated to obtain the first updated load setting value and the second updated load setting value of the pumped storage unit to be analyzed. Then, the first updated capacity setting value, the second updated capacity setting value, the first updated load setting value and the second updated load setting value are input into the pre-trained load transfer instruction prediction model to obtain the target load transfer instruction corresponding to the pumped storage unit to be analyzed. Finally, according to the target load transfer instruction, the corresponding load transfer processing is performed on the pumped storage unit to be analyzed. Specifically, it includes the following contents:

[0199] The pumped storage units in this scheme are managed and controlled by dispatching system A and dispatching system B. The two dispatching systems will increase or decrease the load and capacity of the pumped storage units according to their respective grid load requirements. Therefore, the load transfer function is often used between the two dispatching systems. The specific steps are as follows:

[0200] M1, load transfer mode start module: the load transfer mode is started by dispatching system A or dispatching system B, and the load setting value and capacity setting value before and after the transfer are set.

[0201] After transfer: QLOG, QCOG, QLOC, QCOC.

[0202] Before transfer: QLEG, QCEG, QLEC, QCEC.

[0203] M2, Dispatch Setting Value Analysis and Judgment Module: judge the setting value of the dispatch setting. If one of the following conditions is met, exit the load transfer mode and send an alarm. The operator can re-perform the load transfer operation;

[0204] (1) The absolute value of the load setting value QLOG of dispatching system A is greater than the absolute value of the capacity setting value QCOG of dispatching system A, or the signs of the load setting value and the capacity setting value of dispatching system A are opposite.

[0205] (2) The absolute value of the load setting value QLOC of dispatching system B is greater than the absolute value of the capacity setting value QCOC of dispatching system B, or the signs of the load setting value and the capacity setting value of dispatching system B are opposite.

[0206] Otherwise, continue with the load transfer.

[0207] M3, set value, execution value and fault tolerance calculation module: calculate the sum of the two dispatching load and capacity set values ​​and the sum of the two dispatching load and capacity execution values ​​(i.e. the values ​​before load transfer):

[0208] The sum of the two dispatch capacity setting values: CAPAO = QCOG + QCOC, formula (5)

[0209] The sum of the two dispatch capacity execution values: CAPAE = QCEG + QCEC, formula (6)

[0210] The sum of the two dispatching load setting values: LOADO = QLOG + QLOC, formula (8)

[0211] The sum of the two dispatching load execution values: LOADE = QLEG + QLEC, formula (9)

[0212] Among them, the capacity setting value fault tolerance rate: CAPA10 = DIFSTM / 100; the load setting value fault tolerance rate: LOAD10 = DIFSTM / 100. DIFSTM is the fault tolerance rate parameter manually set in the system interface.

[0213] M4, fault tolerance analysis and judgment module: calculate whether the difference between the sum of the load and capacity setting values ​​of the two dispatches and the sum of the execution values ​​is greater than the fault tolerance rate. If the difference is greater than the fault tolerance rate, the load transfer mode is exited and an alarm is issued. The load and capacity setting values ​​of the two dispatches are maintained at the values ​​before the transfer, and the operator can perform the load transfer operation again.

[0214] If the difference is less than the fault tolerance rate, that is, within the fault tolerance range, the load transfer mode continues and the difference is calculated.

[0215] The difference between the capacity setting value and the execution value: DIFF1 = CAPAE – CAPAO, formula (7)

[0216] The difference between the load setting value and the execution value: DIFF2 = LOADO – LOADE, formula (10)

[0217] M5, set value calculation module after load transfer: calculates the load and capacity set values ​​of the two dispatches after load transfer.

[0218] QCOG ' = QCOG + DIFF1*QCOG / (QCOG-QCOC), formula (1)

[0219] QCOC ' = QCOC + DIFF1*QCOC / (QCOG-QCOC), formula (2)

[0220] QLOG ' = QLOG + DIFF2*QLOG / (QLOG-QLOC), equation (3)

[0221] QLOC ' = QLOC + DIFF2*QLOC / (QLOG-QLOC), equation (4)

[0222] M6, load transfer calculated set value analysis and judgment module: judge the load and capacity set values ​​of the two dispatches calculated by the load transfer program. If one of the following conditions is met, exit the load transfer mode and issue an alarm. The load and capacity set values ​​of the two dispatches maintain the values ​​before the transfer, and the duty officer can re-perform the load transfer operation;

[0223] (1) The absolute value of the load setting value QLOG' of dispatching system A is greater than the absolute value of the capacity setting value QCOG' of dispatching system A, or the signs of the load and capacity setting values ​​of dispatching system A are opposite.

[0224] (2) The absolute value of the load setting value QLOC' of dispatching system B is greater than the absolute value of the capacity setting value QCOC' of dispatching system B, or the signs of the load and capacity setting values ​​of dispatching system B are opposite.

[0225] Otherwise, continue with the load transfer.

[0226] M7, load transfer mode end module: After calculating the required set value according to the load transfer program, the host computer monitoring system allows the load transfer mode to end.

[0227] M8, execute load transfer calculation result module: determine whether the load setting value calculated by load transfer is greater than the capacity setting value. If it is greater, it will not be executed; if it is less than or equal to, the load and capacity setting values ​​will be written into the load and capacity execution values ​​for execution.

[0228] In the above-mentioned embodiment, during the process of load transfer for the pumped-storage unit, multi-dimensional data associated with different aspects of the pumped-storage unit to be analyzed is obtained, and a series of processing such as difference processing, update processing, and model processing are performed to avoid relying on a single data for judgment, so that a more accurate load transfer instruction for the pumped-storage unit to be analyzed can be obtained, and then the corresponding load transfer processing can be performed more accurately on the pumped-storage unit to be analyzed, which is beneficial to improving the load transfer accuracy of the pumped-storage unit; moreover, the whole process does not require human intervention, avoiding the defect of low load transfer accuracy of the pumped-storage unit caused by subjective factors and prone to errors in the manual adjustment method, thereby improving the load transfer accuracy of the pumped-storage unit.

[0229] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
