[0002] With global climate change and population growth, the contradiction between water supply and demand is becoming increasingly severe. As an important water resource regulation hub, reservoir optimization and scheduling are of great significance for alleviating water shortage, ensuring flood control safety, promoting agricultural production and maintaining the ecological environment.

[0003] Traditional reservoir operation methods often use conventional optimization algorithms, which have many limitations in the solution process. For example, they may lack pertinence and find it difficult to make optimal decisions in complex and changeable actual situations; at the same time, they may also search randomly in a large range of space, resulting in low search efficiency and poor solution quality. In particular, when faced with optimization solutions involving multiple complex objectives such as large-scale reservoir group coordination, traditional methods are even more incapable of coping.

[0029] S4, determining the dispatching level of the reservoir according to the dispatching score, and taking the first reservoir to be discharged with the highest dispatching level and the first reservoir to be stored with the highest dispatching level as the first reservoir; In some embodiments, the scheduling level of reservoirs (including reservoirs to be flooded and reservoirs to be stored) can be divided into four levels, and each scheduling level corresponds to a corresponding scheduling score value range, such as scheduling scores: reservoirs with 76 points to 100 points are divided into level A (most urgent scheduling), reservoirs with scheduling scores of 51 points to 75 points are divided into level B (normal scheduling), reservoirs with scheduling scores of 26 points to 50 points are divided into level C (low priority scheduling), and reservoirs with scheduling scores of 0 points to 25 points are divided into level D (least urgent scheduling); the reservoir of level A is taken as the first reservoir, wherein the reservoir of level A to be flooded is determined as the first reservoir to be flooded, and the reservoir of level A to be stored is determined as the first reservoir to be stored.

[0030] S5. Determine the total dispatching flow Q of the first reservoir according to the maximum flood discharge flow of the first reservoir to be discharged and the maximum water storage flow of the first reservoir to be stored. 2 ; Furthermore, the S5 specifically includes: The maximum flood discharge of each first flood discharge reservoir is accumulated to determine the total flood discharge; The maximum water storage flow of each first reservoir to be impounded is accumulated to determine the total water storage data; The minimum value of the total flood discharge and the total water storage flow is taken as the total dispatching flow Q of the first reservoir. 2 .

[0031] It is worth noting that the maximum flood discharge flow is the flood discharge flow when the downstream gates of the reservoir are opened to the maximum extent, the maximum water storage flow is the water storage flow when the upstream gates of the reservoir are opened to the maximum extent, and the total dispatching flow is the sum of the flood discharge flows of all reservoirs to be discharged when the river water level changes, or the sum of the water storage flows of all reservoirs to be stored.

[0032] S6. Obtain the maximum flow rate Q of the river 1 , the total dispatching flow of the first reservoir Q 2 and the maximum flow rate of the river Q 1 Performing comparison, and determining the first dispatching flow of each first reservoir in combination with the dispatching score of the first reservoir; Furthermore, the S6 specifically includes: Get the maximum flow rate Q of the river 1 ; The total dispatching flow of the first reservoir Q 2 and the maximum flow rate of the river Q 1 For comparison: When Q 1 ≤Q 2 When the maximum flow rate of the river is Q 1 Determine the maximum dispatch flow Q 3 , the dispatching score of each first reservoir is accumulated to determine the total dispatching score; The maximum dispatching flow Q is calculated based on the ratio of the dispatching score of each first reservoir to the total dispatching score. 3 Perform flow distribution and determine the first dispatching flow of each first reservoir; When Q 1 >Q 2 When the maximum flood discharge flow of the first reservoir to be discharged or the maximum water storage flow of the first reservoir to be stored is used as the first dispatching flow of each first reservoir.

[0033] It should be noted that the maximum flow rate of the river is Q 1 It is determined based on the cross-sectional area of ​​the river, which is the product of the cross-sectional area and the water flow rate. When regulating the water source of the reservoir, priority should be given to ensuring that the water source regulation flow is not greater than the maximum flow of the river. 1 With the total dispatch flow Q 2 For comparison, when Q 1 >Q 2 When the first reservoir is the first reservoir to be flooded, the first dispatching flow of the first reservoir is determined according to the maximum flood discharge flow; when the first reservoir is the first reservoir to be stored, the first dispatching flow of the first reservoir is determined according to the maximum storage flow. The first dispatch flow. When Q 1 ≤Q 2 When Q 3 = Q 1 , that is, the maximum flow rate of the river is Q 1 As the maximum dispatch flow Q 3 , used for subsequent flow distribution, the dispatching score of each reservoir is accumulated to obtain the total dispatching score. This means that the dispatching scores of all first reservoirs (multiple reservoirs in the first reservoir) are counted, and the total dispatching score of these reservoirs is calculated, and the score ratio of each reservoir is calculated, that is, the proportion of the dispatching score of each reservoir to the total dispatching score. According to the score ratio of each reservoir, the maximum dispatching flow Q 3 For flow allocation, the first dispatching flow of each reservoir (i.e. the flow that needs to be dispatched by the reservoir) will be the maximum dispatching flow Q 3 This allocation method can better ensure the fairness and accuracy of flow distribution when multiple reservoirs need to be dispatched, and adapt to different dispatching needs.

[0034] S7, adjusting each first reservoir gate according to the first dispatching flow of each first reservoir; S8. According to the real-time water level of each first reservoir, adjusting the real-time first dispatching flow of each first reservoir, specifically including: S8.1. Sort each of the first reservoirs according to the dispatching score from high to low; if the dispatching levels are the same, the reservoir to be discharged is ranked first; S8.2. Determine the second dispatching flow according to the real-time water level of the reservoir with the highest dispatching score among the first reservoirs; further, S8.2 specifically includes: Obtain the real-time water level height of the reservoir with the highest scheduling score among the first reservoirs; Calculate the real-time dispatching score of the reservoir with the highest dispatching score among the first reservoirs according to the real-time water level height of the reservoir with the highest dispatching score among the first reservoirs; When the real-time dispatching score of the reservoir with the highest dispatching score in the first reservoir is less than a preset dispatching score threshold, determining the second dispatching flow according to the corresponding relationship between the dispatching score and the dispatching flow; S8.3. Determine the real-time first dispatching flow of each first reservoir according to the first dispatching flow and the second dispatching flow of each first reservoir; specifically including: Adjusting the first dispatching flow of the reservoir with the highest dispatching score among the first reservoirs to the second dispatching flow as the real-time first dispatching flow of the reservoir with the highest dispatching score among the first reservoirs; Calculate a first difference flow between a first dispatching flow and a second dispatching flow of the reservoir with the highest dispatching score among the first reservoirs; Determine the first compensatory dispatching flow of other first reservoirs according to the first difference flow and the dispatching score ratio of other first reservoirs; the other first reservoirs refer to the first reservoirs other than the reservoir with the highest dispatching score among the first reservoirs; The first compensating dispatching flow of other first reservoirs is accumulated with the first dispatching flow of the corresponding other reservoirs to determine the real-time first dispatching flow of the other first reservoirs.

[0035] S8.4. Repeat steps S8.2 to S8.3 in sequence according to the ranking of each reservoir until the real-time first dispatching flow of all reservoirs in the first reservoir is the maximum flood discharge flow or the maximum water storage flow, or the real-time first dispatching flow of each first reservoir does not reach the first dispatching flow.

[0036] In some embodiments, during the water source dispatching process of the first reservoir, the real-time water level height of the first reservoir is collected by the sensor device set in the reservoir, and the real-time dispatching score of the first reservoir is calculated in combination with the water use score of the reservoir. The preset dispatching score threshold is set by those skilled in the art according to actual needs. When the real-time dispatching score of the first reservoir is less than the preset dispatching score threshold, the real-time dispatching score is input into the dispatching score and dispatching flow corresponding curve (the system establishes a dispatching score model based on the reservoir related information collected in a certain period of time in the past, and on the basis of the constructed score model, different dispatching scores are matched with corresponding dispatching flows, and the corresponding curve of dispatching score and dispatching flow is drawn), and the corresponding second dispatching flow is determined, and the first dispatching flow of the first reservoir is adjusted to the second dispatching flow, and the second dispatching flow is adjusted according to the real-time dispatching score. At the same time, the first compensatory dispatching flow of each other first reservoir is determined according to the score ratio of the dispatching score of other first reservoirs to the total dispatching score. The first compensatory dispatching flow of other first reservoirs is accumulated with the current first dispatching flow to determine the adjusted first dispatching flow. It is worth noting that when the real-time dispatching score of the reservoir with the highest dispatching score among the first reservoirs does not exceed the preset dispatching score threshold, no adjustment is made, and the analysis of the next first reservoir is carried out according to the dispatching score sorting.

[0037] S9. When the real-time first dispatching flow of each first reservoir does not reach the first dispatching flow, or the real-time first dispatching flow of all reservoirs in the first reservoir is the maximum flood discharge flow or the maximum water storage flow, the reservoir of the next dispatching level is adjusted to the first reservoir for water source dispatching.

[0038] Exemplarily, first, it is necessary to perform a real-time dispatching flow check on each reservoir in the first reservoir, and check the real-time dispatching flow of each reservoir (such as the "first reservoir to be discharged" and the "first reservoir to be stored"), and the real-time flow can be the current flow calculated by sensors, monitoring equipment or systems. For each reservoir, if its real-time first dispatching flow is lower than the calculated first dispatching flow, it is considered that the flow does not meet the standard. Next, it is determined whether the real-time first dispatching flow of all reservoirs is the maximum flood discharge flow or the maximum water storage flow. For flood discharge reservoirs, if the real-time flow reaches the maximum flood discharge flow; for water storage reservoirs, if the real-time flow reaches the maximum water storage flow, it is determined to be "maximum flow". If the real-time flow of all reservoirs has reached the maximum flow (flood discharge or water storage), it means that these reservoirs can no longer bear more flow dispatching, which means that adjustment is required. When one of the above two situations occurs, it is necessary to perform reservoir level adjustment, and select the reservoir of the next dispatching level according to the hierarchical structure of the dispatching system. For example, if the current reservoir is a Class A reservoir, a Class B reservoir can be selected as an alternative. Adjust the next-level reservoir to the first reservoir, upgrade its scheduling task to the level of the first reservoir, and carry out further water source scheduling.

[0039] When the first reservoir cannot meet the dispatching requirements, the system adjusts the reservoir level and flexibly brings the reservoir of the next dispatching level to the first reservoir. Even if the first reservoir cannot work normally, the system ensures that the flow demand is met by adjusting the reservoir level. Through this mechanism, the system can respond to emergencies or complex dispatching requirements and ensure that the dispatching process continues to be smooth.

[0040] Furthermore, a flood prevention and benefit-promoting intelligent dispatching method also includes: When the real-time first dispatching flow of the other first reservoir is greater than the first dispatching flow of the reservoir, the first dispatching flow of the other reservoir is used as the real-time dispatching flow of the other first reservoir.

[0041] It is worth noting that when the reservoir gate is opened to the maximum extent, the flood discharge or water storage flow through the gate is affected by the actual environment. In actual operation, due to the influence of environmental conditions, equipment capacity and other factors, the maximum flow that can be achieved when the reservoir gate is opened to the maximum extent. This flow may be lower than the designed maximum flow, especially in extreme weather, equipment failure or other operational restrictions. Therefore, when the actual maximum flow is less than the first dispatching flow, water source dispatching is carried out according to the actual maximum flow.

[0042] The present invention also provides a flood prevention and benefit-promoting intelligent dispatching system, which is used to implement the above-mentioned flood prevention and benefit-promoting intelligent dispatching method, comprising: The first data acquisition module: acquires reservoir water use data and meteorological forecast data for time interval tn; A first data analysis module: connected to the first data acquisition module, used to determine the type of reservoir according to the reservoir water use data and meteorological forecast data in the time interval tn, the reservoir type including: a reservoir to be flooded and a reservoir to be stored; determine the dispatching score of the reservoir according to the reservoir water use data in the time interval tn; determine the dispatching level of the reservoir according to the dispatching score, and use the first reservoir to be flooded with the highest dispatching level and the first reservoir to be stored with the highest dispatching level as the first reservoir; determine the total dispatching flow Q2 of the first reservoir according to the maximum flood discharge flow of the first reservoir to be flooded and the maximum water storage flow of the first reservoir to be stored; The second data acquisition module is used together with the first data analysis module to obtain the maximum flow rate Q of the river. 1 ; The second data analysis module: connected to the second data acquisition module, compares the total dispatching flow Q2 of the first reservoir with the maximum flow Q1 of the river, and determines the first dispatching flow of each first reservoir in combination with the dispatching score of the first reservoir; adjusts the gate of each first reservoir according to the first dispatching flow of each first reservoir; adjusts the real-time first dispatching flow of each first reservoir according to the real-time water level of each first reservoir; when the real-time first dispatching flow of each first reservoir does not reach the first dispatching flow, or the real-time first dispatching flow of all the reservoirs in the first reservoir is the maximum flood discharge flow or the maximum water storage flow, adjusts the reservoir of the next dispatching level to the first reservoir for water source dispatching.
