[0002] The joint scheduling of a reservoir group refers to the unified coordinated scheduling of reservoirs and related engineering facilities with hydrological and hydraulic interrelationships within a basin. It has become one of the key concerns because it can maximize the water conservancy benefits within the basin.

[0003] Currently, the prior art usually generates a fixed storage and release mechanism for the reservoir group based on the empirical method, regulation capacity method or remaining flood control storage method, and realizes the joint scheduling of the reservoir group based on the fixed storage and release mechanism.

[0061] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation of the present application. For the step numbers in the following embodiments, they are only set for the convenience of elaboration and explanation, and no limitation is imposed on the order between the steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0063] Before introducing the embodiments of the present application, the nouns related to the embodiments of the present application are explained as follows:

[0064] The storage and discharge sequence refers to the orderly arrangement of the water storage and discharge of each storage and discharge reservoir in the reservoir group;

[0065] The storage and discharge time refers to the orderly arrangement of the water storage time and discharge time of each storage and discharge reservoir in the reservoir group;

[0066] The control water level refers to the reservoir water level that changes with time during the water storage and discharge processes of the storage and discharge reservoir;

[0067] Currently, the prior art usually realizes the joint operation of the reservoir group based on the empirical method, the regulation capacity method, or the remaining flood control storage method. Specifically:

[0068] The empirical method usually generates the storage and discharge mechanism of the reservoir group based on information such as the geographical location and safe operation requirements of the reservoir group and long-term operation experience. The storage and discharge mechanism can specifically be that the upstream reservoir stores water first and then discharges water, and the downstream reservoir discharges water first and then stores water, etc. Its storage and discharge mechanism is relatively fixed and often cannot be dynamically adjusted according to the actual situation. Moreover, it only considers the control of the storage and discharge sequence and ignores the influence of the control water level and the storage and discharge time on the operation effect of the reservoir group;

[0069] The regulation capacity method usually sets the storage and discharge mechanism of the storage and discharge reservoir with a larger regulation capacity in the reservoir group to store water first and then discharge water, and sets the storage and discharge mechanism of the storage and discharge reservoir with a smaller regulation capacity to discharge water first and then store water. The regulation capacity method is similar to the empirical method. Its storage and discharge mechanism is relatively fixed and often cannot be dynamically adjusted according to the actual situation. Moreover, it only considers the control of the storage and discharge sequence and ignores the influence of the control water level and the storage and discharge time on the operation effect of the reservoir group;

[0070] The remaining flood control storage capacity method usually generates the storage and discharge mechanism of a reservoir group based on the remaining flood control storage capacity of each storage and discharge reservoir in the reservoir group. This storage and discharge mechanism is usually a fixed one and often cannot be dynamically adjusted according to the actual situation. Moreover, it only considers the control of the storage and discharge sequence and ignores the influence of the control water level and the storage and discharge time on the operation effect of the reservoir group.

[0071] In addition, there are also some existing technologies that realize the joint operation of reservoir groups based on the flood area composition method or the index method. Among them, the flood area composition method generates the storage and discharge mechanism of the reservoir group according to the confluence time in the basin or the difference in the impounding effect of each storage and discharge reservoir. This method requires a large amount of data to summarize the composition law of the flood area, has high requirements for hydrological data and hydro-meteorological data, and is difficult to analyze data, making it difficult to generate a dynamically adjustable storage and discharge mechanism.

[0072] The index method usually determines the storage and discharge mechanism of the reservoir group based on index data such as the reservoir regulation capacity, evaporation ratio, water storage index line, water shortage index, and K value. The basic control principle is to discharge water when the index data exceeds the index threshold and store water when the index data is lower than the index threshold. This method has low operability for the scheduling of the storage and discharge mechanism and ignores the influence of the storage and discharge sequence on the operation effect of the reservoir group.

[0073] Furthermore, among the above existing methods, only the index method is applicable to the beneficial operation scenario of the reservoir group, while the flood area composition method, the remaining flood control storage capacity method, the regulation capacity method, and the empirical method are applicable to the flood control operation scenario of the reservoir group. They cannot well balance the flood control operation characteristics and the beneficial operation characteristics of the reservoir group, and the applicable scope of these methods is relatively limited.

[0074] In view of this, the embodiments of the present invention provide a method, system, device, and medium for the joint operation of a reservoir group. Among them, this method can obtain a more targeted dynamically adjustable storage and discharge mechanism for the target reservoir group by screening the optimal scheduling strategy for the first storage and discharge scheduling strategy and screening the optimal storage and discharge sequence for the reservoir storage and discharge sequence set through the target storage and discharge scheduling strategy. This storage and discharge mechanism includes the target storage and discharge scheduling strategy and the target storage and discharge sequence, which can effectively improve the flexibility and operation effect of the joint operation of the reservoir group.

[0075] In addition, this method is based on the target storage and discharge sequence and the target storage and discharge scheduling strategy. The target storage and discharge scheduling strategy includes the storage and discharge time and the control water level, and can realize the joint operation of the reservoir group from multiple dimensions of the storage and discharge sequence, the storage and discharge time, and the control water level, which can further improve the operation effect of the joint operation of the reservoir group.

[0076] In addition, this method is based on screening the optimal scheduling strategy for the first storage and release skipping strategy. Specifically, through the intermediate storage and release order, the inflow flood discharge, and the channel safety discharge, flood routing calculation is performed on the first storage and release scheduling strategy, and then the water level condition verification of the target storage level is carried out through the flood routing calculation data. It can better take into account the flood control operation characteristics and water utilization operation characteristics of the reservoir group, which is beneficial to improving the applicable range of the joint scheduling of the reservoir group.

[0077] Refer to Figure 1 , in the embodiment of the present application, a method for joint scheduling of a reservoir group includes:

[0078] Step 110, obtain the reservoir storage and release order set of the target reservoir group, where the reservoir storage and release order set includes several intermediate storage and release orders;

[0079] In the embodiment of the present application, the target reservoir group may be a reservoir group composed of storage and release reservoirs at different positions in a certain basin, and the target reservoir group includes several storage and release reservoirs; the reservoir storage and release order set is a set of intermediate storage and release orders, and each intermediate storage and release order is used to represent a storage and release order in the target reservoir group.

[0080] In some embodiments, the step 110, obtain the reservoir storage and release order set of the target reservoir group, includes:

[0081] A1. Obtain the storage and release order control index of each storage and release reservoir of the target reservoir group, and obtain the synchronous storage and release order of the target reservoir group;

[0082] A2. According to all the storage and release order control indexes, perform initial order generation on the target reservoir group to obtain a first storage and release order and a second storage and release order, where the first storage and release order is the storage and release order generated in sequence, and the second storage and release order is the storage and release order generated in reverse order;

[0083] A3. Perform intermediate order adjustment on the first storage and release order and the second storage and release order to obtain several third storage and release orders;

[0084] A4. According to the synchronous storage and release order, the first storage and release order, the second storage and release order, and all the third storage and release orders, obtain the reservoir storage and release order set.

[0085] In the embodiment of the present application, the storage and release order control index may be indexes such as the regulation capacity of the storage and release reservoir, the remaining flood control storage capacity, the remaining water utilization storage capacity, and the effective water storage rate; the synchronous storage and release order of the target reservoir group may be the order in which each storage and release reservoir in the target reservoir group stores water or releases water simultaneously.

[0086] It can be understood that step A2 can be to generate the first storage and release order sequentially and the second storage and release order in reverse order based on the magnitude sorting relationship of the storage and release order control indicators corresponding to each storage and release reservoir in the target reservoir group. Step A3 can be to randomly adjust the order numbers of each storage and release reservoir between the first storage and release order and the second storage and release order to generate several third storage and release orders.

[0087] It should be noted that step A4 can be to construct a reservoir storage and release order set based on the synchronous storage and release order, the first storage and release order, the second storage and release order, and all the third storage and release orders. The intermediate storage and release order in this reservoir storage and release order set can be any one of the synchronous storage and release order, the first storage and release order, the second storage and release order, or the third storage and release order.

[0088] Exemplarily, if the target reservoir group includes four storage and release reservoirs, an incompletely exhaustive reservoir storage and release order set can be as shown in Table 1 below:

[0089] Table 1

[0090]

[0091] It is worth mentioning that "3-2 first storage and first release" in Table 1 is used to represent that in the storage and release order of storage and release reservoir 2 and storage and release reservoir 3, storage and release reservoir 3 has priority in water storage and priority in water release compared with storage and release reservoir 2; "3-2 first storage and then release" in Table 1 is used to represent that in the storage and release order of storage and release reservoir 2 and storage and release reservoir 3, storage and release reservoir 3 has priority in water storage, while storage and release reservoir 2 has priority in water release compared with storage and release reservoir 2; "2-3 first storage and first release" and "2-3 first storage and then release" in Table 1 are similar to the foregoing content and can be simply deduced by analogy.

[0092] Step 120, obtain a first storage and release scheduling strategy, an inflow discharge data set, and a river channel discharge data set. The inflow discharge data set is a set of the inflow flood discharges of the target reservoir group, and the river channel discharge data set is a set of the river channel safety discharges of the target reservoir group. Each of the inflow flood discharges corresponds to one of the river channel safety discharges;

[0093] In the embodiments of the present application, the inflow discharge data set includes several inflow flood discharges. Each inflow flood discharge is used to represent the inflow discharge of the target reservoir group in a certain time period, and the time periods corresponding to each inflow flood discharge are different; the river channel discharge data set includes several river channel safety discharges. Each river channel safety discharge is used to represent the maximum discharge that can be safely discharged in the basin where the target reservoir group is located.

[0094] It can be understood that the first storage and release scheduling strategy can be an initial storage and release scheduling strategy or a first storage and release scheduling strategy obtained after strategy update during the screening process of the previous optimal scheduling strategy.

[0095] In some embodiments, step 120, obtaining the first storage and discharge scheduling strategy, includes:

[0096] B1. Obtain the initial operating water level, water level variation limit, target storage water level, and target time of the target storage water level of the policy reservoir, where the policy reservoir is any storage and discharge reservoir in the target reservoir group;

[0097] B2. According to the water level variation limit, the target storage water level, and the target time, perform water level inversion on the initial operating water level to obtain the storage and discharge time and control water level data, where the control water level data is used to record the control water level of the policy reservoir between the storage and discharge time and the target time;

[0098] B3. According to all the storage and discharge times and all the control water level data, obtain the first storage and discharge scheduling strategy.

[0099] In the embodiments of the present application, if the obtained first storage and discharge scheduling strategy is the initial storage and discharge scheduling strategy, it may be to obtain the storage and discharge time and control water level data of each storage and discharge reservoir respectively. Then, taking any storage and discharge reservoir in the target reservoir as the policy reservoir, step B1 may be to obtain the initial operating water level of the policy reservoir in the current period, as well as the water level variation limit during the safe operation of the policy reservoir, the target storage water level of the policy reservoir, and the target time when reaching the target storage water level.

[0100] It can be understood that step B2 may use the target storage water level as the starting point of the calculation, use the maximum water level rise threshold or the maximum water level drop threshold in the water level variation limit as the water level change rate, and inversely deduce the duration required for the water level of the policy reservoir to reach the initial operating water level from the target storage water level, and determine the storage and discharge time based on this duration and the target time, and use the control water level of each period between the target time and the storage and discharge time of the policy reservoir as the control water level data.

[0101] It should be noted that the same applies to the remaining storage and discharge reservoirs. After obtaining the storage and discharge time and control water level data of each storage and discharge reservoir respectively, the first storage and discharge scheduling strategy of the target reservoir group can be constructed for the storage and discharge time and control water level data of each storage and discharge reservoir.

[0102] Step 130. According to several of the intermediate storage and discharge orders, all the inflow flood discharges, and all the channel safety discharges, screen the first storage and discharge scheduling strategy to obtain the target storage and discharge scheduling strategy;

[0103] In the embodiments of the present application, based on one or more intermediate storage and release sequences, as well as all the incoming flood flows and the river channel safety flows, the first storage and release scheduling strategy can be dynamically adjusted and optimally selected to obtain the optimal storage and release scheduling strategy, and this optimal storage and release scheduling strategy is determined as the target storage and release scheduling strategy.

[0104] In some embodiments, step 130, screening the optimal scheduling strategy for the first storage and release scheduling strategy according to several of the intermediate storage and release sequences, all the incoming flood flows, and all the river channel safety discharges to obtain the target storage and release scheduling strategy, includes:

[0105] C1. Obtain the target storage levels of each storage and release reservoir in the target reservoir group;

[0106] C2. Conduct flood routing calculations on the first storage and release scheduling strategy according to several of the intermediate storage and release sequences, all the incoming flood flows, and all the river channel safety discharges to obtain flood routing calculation data;

[0107] Further, step C2, conducting flood routing calculations on the first storage and release scheduling strategy according to several of the intermediate storage and release sequences, all the incoming flood flows, and all the river channel safety discharges to obtain flood routing calculation data, includes:

[0108] C21. Use the first storage and release scheduling strategy at the current calculation period as the second storage and release scheduling strategy, and obtain the first remaining scheduling target corresponding to the second storage and release scheduling strategy;

[0109] C22. Screen the incoming flow data for all the incoming flood flows according to the second storage and release scheduling strategy to obtain the target incoming flow corresponding to the second storage and release scheduling strategy, and screen the river channel discharge data for all the river channel safety discharges according to the second storage and release scheduling strategy to obtain the target river channel discharge corresponding to the second storage and release scheduling strategy;

[0110] C23. Construct a scheduling target for the target incoming flow and the target river channel discharge according to the first remaining scheduling target and the second storage and release scheduling strategy to obtain the first scheduling target;

[0111] In an embodiment of the present application, step C2 may be to obtain flood routing calculation data based on one or more intermediate storage and release sequences, all incoming flood flows, and all river channel safety flows. Specifically, since the first storage and release scheduling strategy is a storage and release scheduling strategy composed of the control water levels of the target reservoir group between the storage and release time and the target time, the first storage and release scheduling strategy records the control water levels of each storage and release reservoir of the target reservoir group at each calculation period. For the first storage and release scheduling strategy (i.e., the second storage and release scheduling strategy) of a certain calculation period, if the calculation period of the second storage and release scheduling strategy is the initial calculation period, its first scheduling remaining target may be empty or zero; or, if the calculation period of the second storage and release scheduling strategy is not the initial calculation period, its first scheduling remaining target may be the second scheduling remaining target corresponding to the intermediate calculation data of the previous calculation period.

[0112] It can be understood that step C22 may be to screen the incoming flood flows of all different periods based on the calculation period corresponding to the second storage and release scheduling strategy, so as to screen out the incoming flood flow in the calculation period of the second storage and release scheduling strategy and determine the incoming flood flow as the target incoming flow; further, the screening of the river discharge data may be to screen the river channel safety discharges of all different periods based on the calculation period corresponding to the second storage and release scheduling strategy, so as to screen out the river channel safety discharge in the calculation period of the second storage and release scheduling strategy and determine the river channel safety discharge as the target river channel discharge.

[0113] Step C23 may be to construct an initial scheduling target based on the control water level, target incoming flow, and target river channel discharge indicated by the second storage and release scheduling strategy, and then determine the first scheduling target by integrating the first scheduling remaining target and the initial scheduling target. The first scheduling target is used to evaluate the total peak shaving amplitude and river channel discharge capacity of the target reservoir group at the current calculation period.

[0114] C24. Perform strategy calculation on the first scheduling target according to several of the intermediate storage and release sequences to obtain intermediate calculation data and the second scheduling remaining target of the intermediate calculation data;

[0115] Further, the step C24, performing strategy calculation on the first scheduling target according to several of the intermediate storage and release sequences to obtain intermediate calculation data, includes:

[0116] C241. Obtain several scheduling water level data corresponding to the first scheduling target, each scheduling water level data corresponding to a storage and release reservoir in the target reservoir group, and the scheduling water level data is used to represent the absolute difference between the operating water level of the corresponding storage and release reservoir and the target storage water level;

[0117] C242. According to a plurality of the intermediate storage and discharge sequences and all the scheduling water level data, perform target allocation and strategy generation for the first scheduling target to obtain the intermediate calculation data.

[0118] In the embodiment of the present application, the operating water levels of each storage and discharge reservoir in the target reservoir group can be respectively obtained in the current calculation period, and then based on the target storage water level of each storage and discharge reservoir, an absolute difference operation is respectively performed with the corresponding operating water level, so as to obtain a plurality of scheduling water level data corresponding to the first scheduling target in the current calculation period.

[0119] It can be understood that in the embodiment of the present application, taking the number of intermediate storage and discharge sequences as 1 as an example, step C42 can be based on the sorting relationship contained in the intermediate storage and discharge sequence, sequentially allocate the scheduling water level data of each storage and discharge reservoir to the first scheduling target, and determine the intermediate calculation data based on the allocated scheduling water level data. The intermediate calculation data records the calculation water levels of each storage and discharge reservoir in the current calculation period, and determines the second scheduling remaining target based on the finally allocated first scheduling target. The same applies to the remaining number of intermediate storage and discharge sequences, and can be simply deduced by analogy.

[0120] Exemplarily, if the intermediate storage and discharge sequence is the "first store and first discharge of 3-2" in Table 1 above, the sorting relationship contained in the intermediate storage and discharge sequence is successively storage and discharge reservoir 3, storage and discharge reservoir 2, storage and discharge reservoir 1, and storage and discharge reservoir 4; for the first scheduling target at the calculation period t Step C42 can first be to obtain the scheduling water level data of storage and discharge reservoir 3, and allocate the scheduling water level data to the first scheduling target. Specifically, if the operating water level of storage and discharge reservoir 3 is greater than or equal to its corresponding target storage water level, it can be the channel discharge capacity in the first scheduling target deduct the scheduling water level data of storage and discharge reservoir 3; or, if the operating water level of storage and discharge reservoir 3 is less than its corresponding target storage water level, it can be the total peak shaving amplitude in the first scheduling target deduct the scheduling water level data of storage and discharge reservoir 3 to obtain the first scheduling target after the first allocation update; then, based on the scheduling water level data of storage and discharge reservoir 2, perform allocation update on the first scheduling target after the first allocation update. The same applies to storage and discharge reservoirs 1 and 4, and can be simply deduced by analogy. The present application will not elaborate here.

[0121] It should be noted that in practical applications, the channel discharge capacity and the total peak shaving amplitude in the first scheduling target both have upper limits. Therefore, the allocation update of the channel discharge capacity in the first scheduling target can be stopped when the channel discharge capacity Stop the allocation update of the total peak shaving amplitude in the first scheduling target. The examples of this application are only for illustration and do not limit this application.

[0122] C25. If the current calculation period is not the last calculation period of the first storage and release scheduling strategy, retain the intermediate calculation data, update the first storage and release scheduling strategy for the current calculation period, and update the first remaining scheduling target according to the second remaining scheduling target. Then return to execute the step of using the first storage and release scheduling strategy for the current calculation period as the second storage and release scheduling strategy and obtaining the first remaining scheduling target corresponding to the second storage and release scheduling strategy;

[0123] Or, C26. If the current calculation period is the last calculation period of the first storage and release scheduling strategy, obtain the flood routing calculation data based on all the intermediate calculation data.

[0124] In the embodiment of this application, after obtaining the intermediate calculation data and the second remaining scheduling target for the current calculation period, if the current calculation period is not the last calculation period of the first storage and release scheduling strategy, it means that there is at least one calculation period in the first storage and release scheduling strategy that has not been calculated. At this time, the intermediate calculation strategy for the current calculation period can be retained, and the first storage and release scheduling strategy for the next calculation period can be used as the second storage and release scheduling strategy in the next strategy calculation process. Also, the second remaining scheduling target for the current calculation period can be used as the first remaining scheduling target in the next strategy calculation process. Then return to execute step C21; or, if the current calculation period is the last calculation period of the first storage and release scheduling strategy, it means that all the calculation periods of the first storage and release scheduling strategy have been calculated. At this time, the scheduling calculation data corresponding to the first storage and release scheduling strategy can be generated based on the intermediate calculation data of each calculation period. The scheduling calculation data records the calculated water levels of each storage and release reservoir in the target reservoir group at each calculation period.

[0125] C3. Verify the water level conditions for all the target storage water levels according to the flood routing calculation data to obtain a water level condition verification result, which is used to represent whether the flood routing calculation data meets all the target storage water levels;

[0126] C4. If the water level condition verification result is that the flood routing calculation data meets all the target storage water levels, determine the first storage and release scheduling strategy as the target storage and release scheduling strategy;

[0127] In an embodiment of the present application, step C3 may be to obtain the calculated water levels of each storage and discharge reservoir at the target time based on the scheduling calculation data, and then verify each calculated water level with the corresponding target storage water level respectively. If all the calculated water levels reach the corresponding target storage water levels, a water level condition verification result indicating that the flood routing calculation data meets all the target storage water levels can be obtained. At this time, the first storage and discharge scheduling strategy corresponding to the flood routing calculation data can be determined as the target storage and discharge scheduling strategy; or, if there is at least one calculated water level that does not reach the corresponding target storage water level, a water level condition verification result indicating that the flood routing calculation data does not meet all the target storage water levels can be obtained.

[0128] Or, C5. If the water level condition verification result is that the flood routing calculation data does not meet all the target storage water levels, update the first storage and discharge scheduling strategy to obtain the updated first storage and discharge scheduling strategy, and then return to execute the steps of obtaining the first storage and discharge scheduling strategy, the inflow dataset, and the river discharge dataset.

[0129] Further, the updating the first storage and discharge scheduling strategy to obtain the updated first storage and discharge scheduling strategy includes:

[0130] C51. Obtain the preset storage and discharge update time and the storage and discharge sequence control index of each storage and discharge reservoir in the target reservoir group;

[0131] C52. Screen all the storage and discharge reservoirs according to the storage and discharge sequence control index to obtain the intermediate reservoir and the storage and discharge update times of the intermediate reservoir;

[0132] C53. Screen the sub-strategies in the first storage and discharge scheduling strategy according to the intermediate reservoir to obtain the reservoir scheduling sub-strategy corresponding to the intermediate reservoir;

[0133] C54. Adaptively update the reservoir scheduling sub-strategy according to the storage and discharge update time and the storage and discharge update times to obtain the updated reservoir scheduling sub-strategy;

[0134] C55. Locally replace and update the first storage and discharge scheduling strategy according to the updated reservoir scheduling sub-strategy to obtain the updated first storage and discharge scheduling strategy.

[0135] In the embodiments of the present application, the specific value of the storage and discharge update time can be flexibly set according to the actual situation, such as any one of 6 hours, 12 hours, 24 hours, 48 hours, etc. This storage and discharge update time is used for the storage and discharge time. In the first feasible implementation manner, step C52 can first randomly select any one of the storage and discharge order control indicators, and determine the corresponding storage and discharge reservoir based on the selected storage and discharge order control indicator, and determine this storage and discharge reservoir as the intermediate reservoir; or, in the second feasible implementation manner, step C52 can first sort the sizes of all storage and discharge order control indicators, and then determine the storage and discharge reservoir corresponding to the largest or smallest storage and discharge order control indicator as the intermediate reservoir.

[0136] It can be understood that step C53 can be to select the reservoir scheduling sub-strategy corresponding to the target reservoir from the first storage and discharge scheduling strategy. This reservoir scheduling sub-strategy records the storage and discharge time and the control water level data of this intermediate reservoir, and this control water level data records the control water level between the storage and discharge time and the target time.

[0137] It should be noted that step C54 can be to update the storage and discharge time of this reservoir scheduling sub-strategy based on the storage and discharge update time. Specifically, taking the storage and discharge update time as a time unit, advance the storage and discharge time of this reservoir scheduling sub-strategy by one time unit to obtain the updated storage and discharge time; and, based on the storage and discharge update times, dynamically update the control water level between the updated storage and discharge time and the target time to obtain the updated control water level data.

[0138] Exemplarily, the dynamic update of the control water level data in the embodiments of the present application can be to advance the control water levels in period t 1 and period t 1 before by one time unit with the storage and discharge update time. This first period can be expressed as:

[0139] t 1 =T - ab + 1

[0140] where T is the original storage and discharge time, a is the storage and discharge update time, and b is the storage and discharge update times.

[0141] And set the control water level after period t 1 to the target storage water level. The example of the update method of the control water level data in the present application is only for illustration. For example, it can also update the control water level at t 2 =T - ab to the average value of this control water level and the target storage water level. The present application does not limit this here.

[0142] It is worth mentioning that after obtaining the updated storage and release time and the updated control water level data, an updated reservoir operation sub-strategy can be generated based on the updated storage and release time and the updated control water level data. Then, based on this updated reservoir operation sub-strategy, the corresponding original reservoir operation sub-strategy in the first storage and release operation strategy is replaced to obtain an updated first storage and release operation strategy, which can be used as the first storage and release operation strategy in the screening process of the next optimal operation strategy. In addition, multiple intermediate reservoirs can also be selected in the embodiments of the present application. In this case, multiple reservoir operation sub-strategies can be updated simultaneously to obtain a first storage and release operation strategy replaced by multiple updated reservoir operation sub-strategies, which will not be elaborated herein.

[0143] Step 140: According to the target storage and release operation strategy, perform optimal storage and release order screening on the reservoir storage and release order set to obtain the target storage and release order.

[0144] In the embodiments of the present application, for the optimal storage and release order screening, first, based on the target storage and release operation strategy, calculate the maximum storage capacity consumption and the storage and release order control index value of the target reservoir group for each intermediate storage and release order in the reservoir storage and release order set respectively; then, with the goal of minimizing the maximum storage capacity consumption, screen out several intermediate storage and release orders; next, based on the goal of optimizing the storage and release order control index value, determine the target storage and release order from the several screened intermediate storage and release orders.

[0145] Step 150: According to the target storage and release operation strategy and the target storage and release order, obtain the joint operation result of the target reservoir group.

[0146] In the embodiments of the present application, after obtaining the target storage and release operation strategy and the target storage and release order, the target storage and release operation strategy and the target storage and release order can be applied to the joint operation of the target reservoir group to obtain the joint operation result of the target reservoir group.
