Description

Technical Field

[0001] The present invention belongs to the technical field of reservoir optimization, and particularly relates to a method for adaptively allocating flood control and water supply of a reservoir and related equipment. Background Art

[0002] At present, the economy is developing rapidly and the urbanization process is accelerating continuously. The demand for water resources in some areas has increased rapidly. To solve the problem of uneven spatio-temporal distribution of water resources, a large number of water conservancy projects have been built to regulate water resources. As an important water resource regulation and storage facility, a reservoir undertakes the task of urban water supply on the one hand, and on the other hand, it also undertakes an important flood control task and takes into account power generation at the same time. The flood control task of the reservoir requires the reservoir to lower the water level during the flood season to ensure that it can accommodate a larger peak flood flow and protect the lives and property safety of the downstream. However, its water supply task requires the reservoir to have a high water level to ensure a high water supply guarantee rate and can also take into account power generation to increase revenue. Therefore, reservoir allocation is a multi-objective and multi-constraint non-linear allocation strategy. However, at present, the operation of multi-objective reservoirs mostly relies on empirical allocation or single-objective optimization models. This traditional allocation method often fails to comprehensively consider the complex relationships and mutual influences among multiple objectives such as flood control, water supply, and power generation of the reservoir, resulting in poor adaptability of the reservoir in flood control and water supply.

Obviously, the following drawings are some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0024] Figure 1 It is a flowchart of a method for adaptively allocating flood control and water supply of a reservoir according to the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0026] As Figure 1 shown, the embodiment of the present invention provides a method for adaptive allocation of reservoir flood control and water supply. By constructing an allocation model that comprehensively considers maximizing reservoir benefits and maximizing the water supply reliability index, the optimal management of reservoir water resources is achieved. The method for adaptive allocation of reservoir flood control and water supply specifically includes the following steps: S1. Under the constraint of ensuring the safe operation of the reservoir, with the goals of maximizing reservoir benefits and maximizing the water supply reliability index, construct an adaptive allocation model for reservoir flood control and water supply.

[0027] In this embodiment, the reservoir benefits consider two parts: water supply benefits and power generation benefits. The water supply benefits are obtained by multiplying the water prices in different regions by the water supply flow rate and time; the power generation benefits are calculated based on the unit price of hydropower grid connection, the efficiency of the water turbine generator set, the net head, the flow rate through the water turbine, and the power generation time. At the same time, a penalty factor for the high water level risk of the reservoir is introduced to reflect the risk cost of dam breakage that may be brought about by too high a water level.

[0028] Specifically, with the goal of maximizing reservoir benefits, specifically:

[0029] In the formula, is the reservoir benefit; is the corresponding reservoir water supply price in different regions, yuan / m 3 ; is t the water intake flow rate at the reservoir water intake at time 3 / s; is the reservoir water supply time, s; is the unit price of hydropower grid connection, yuan; is the efficiency of the water turbine of the water turbine generator set, generally taking values between 0.8 and 0.9; is t the net head at time is t the flow rate through the water turbine at time 3 / s; is the operation time of the water turbine generator, s. This model conducts allocation on a second scale, so the time duration is taken as 1 s; is the penalty factor for the risk of dam breakage of the reservoir caused by the high water level of the reservoir; ist Reservoir water level at a certain moment, m.

[0030] In this embodiment, the water supply reliability index is measured by calculating the proportion of the duration during which the water supply volume meets the demand in each water supply period within the entire allocation period, ensuring the stable and reliable water supply service.

[0031] Specifically, with the goal of maximizing the water supply reliability index, specifically:

[0032] In the formula, is the water supply reliability index; is the total water supply duration within the entire allocation period; is the water supply period i The duration during which the water supply volume meets the water supply demand.

[0033] In this embodiment, the reservoir safe operation constraints include water balance constraint, reservoir storage capacity constraint, water level constraint, flood discharge flow constraint, water supply flow constraint, and reservoir power generation flow constraint. The specific situations of each constraint are as follows: The water balance constraint takes into account factors such as the upstream inflow of the reservoir, precipitation, evaporation loss, seepage loss, flood discharge flow, and water intake flow to ensure the dynamic balance of water volume. Specifically, the water balance constraint is specifically:

[0034] In the formula, is the incoming water runoff at the upstream inflow control section t of the reservoir at a certain moment, m 3 / s; is the calculation time length, s; is t the precipitation per unit time at a certain moment, m / m 2 *s; is the reservoir water surface area, m 2 ; is the evaporation loss of the reservoir within the 3 time period, m is the seepage loss of the reservoir within the 3 time period, m is t the flood discharge flow of the reservoir at a certain moment, m 3 / s.

[0035] It should be noted that before establishing the water balance constraint, the water level and reservoir capacity data of the target reservoir, as well as the water level and reservoir water surface area data, are first collected. The polyfit function in MATLAB is used to fit the water level and reservoir capacity data and the water level and reservoir water surface area data respectively, and the reservoir capacity - water level fitting relationship and the reservoir water surface area - water level fitting relationship are obtained respectively. The parameters required for the water balance constraint can be obtained according to the reservoir capacity - water level fitting relationship and the reservoir water surface area - water level fitting relationship.

[0036] The reservoir capacity constraint sets the minimum and maximum reservoir capacity limits to prevent potential safety hazards caused by excessive or insufficient water volume. Specifically, the reservoir capacity constraint is as follows:

[0037] In the formula, is the minimum allowable reservoir capacity, m 3 ; is the maximum allowable reservoir capacity, m 3 ; is the initial water volume of the reservoir, m 3 .

[0038] It should be noted that according to the reservoir capacity - water level fitting relationship, the reservoir capacities at the lowest and highest water levels are found .

[0039] The water level constraint stipulates that the water level of the reservoir at any time must be between the allowable minimum and maximum water levels to ensure the safety of the reservoir structure and the surrounding areas. Specifically, the water level constraint is as follows:

[0040] In the formula, is the water level of the reservoir at t time, m; is the minimum allowable water level of the reservoir at t time, m; is the maximum allowable water level of the reservoir at t time, m.

[0041] The flood discharge flow constraint limits the maximum flood discharge flow to prevent threats to the downstream caused by excessive flood discharge flow. Specifically, the flood discharge flow constraint is as follows:

[0042] In the formula, is the maximum flood discharge flow of the reservoir.

[0043] The water supply flow constraint sets the maximum water intake flow at the water intake to ensure that the water intake activity will not have too much impact on the reservoir water level. Specifically, the water supply flow constraint is as follows:

[0044] Wherein, is the maximum water intake flow allowed at the reservoir water intake.

[0045] The reservoir power generation flow constraint stipulates the upper limit of the flow passing through the water turbine to ensure the safe and efficient operation of the water turbine. Specifically, the reservoir power generation flow constraint is specifically:

[0046] Wherein, is the upper limit of the flow allowed to pass through the water turbine.

[0047] In one embodiment, in MATLAB, using the modeling language of Yalmip, the variables, parameters, objective function, and constraint conditions defined above are integrated into a complete reservoir flood control and water supply adaptive allocation model.

[0048] S2. Solve the reservoir flood control and water supply adaptive allocation model to obtain a reservoir flood control and water supply adaptive allocation plan.

[0049] In this embodiment, the constructed reservoir flood control and water supply adaptive allocation model is passed to the Cplex solver for solution. After the Cplex solver returns the solution result, MATLAB is used to analyze the result, extract the water volume allocation strategies for each time period in the optimal allocation plan, and calculate the obtained maximum benefit value.

[0050] S3. Perform reservoir flood control and water supply adaptive allocation according to the reservoir flood control and water supply adaptive allocation plan.

[0051] That is to say, according to the obtained reservoir flood control and water supply adaptive allocation plan, a specific reservoir operation plan is formulated. For example, including but not limited to adjusting the flood discharge strategy, optimizing the water supply flow, arranging the power generation time period, etc., to ensure maximizing the reservoir benefit and water supply reliability while meeting the flood control requirements.

[0052] Exemplarily, using Yalmip modeling + Cplex to solve the multi-objective and multi-constraint nonlinear optimal solution provides guidance for the reservoir water volume allocation. This method greatly reduces the complexity of modeling and solution. During the actual operation process, if the original measured data can be continuously and real-timely output, the model can realize real-time synchronous output of the allocation plan. In addition, the Yalmip + Cplex combination used in this model can easily adapt to different scales and types of optimization problems, and can be adapted to different types of reservoirs by modifying their objective functions and constraint conditions.
