Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Specific steps are as follows:

[0036] 1. Choose to participate in the calculation of the reservoir, and set the water level, output, flow range of each reservoir, system output range and other constraints, termination conditions ε and other parameters

[0037] 2. Select the optimal calculation method according to the number N of reservoirs involved in the calculation.

[0038] If more than one reservoir is involved in the calculation, go to step 3; otherwise, use the stepwise optimization algorithm to solve directly.

[0039]3. Set the discrete number L of the water level, and select an appropriate orthogonal table from the reservoir number N and the discrete number L.

[0040] Reservoir is the test factor, its number N is the total number of columns in the orthogonal table, the number of discrete states of water level L is regarded as the factor leve...

Abstract

The invention relates to the field of reservoir scheduling and discloses an orthogonal successive approximation algorithm based reservoir scheduling method. The reservoir scheduling method includes the steps: firstly, determining number of reservoirs, and adopting the orthogonal successive approximation algorithm for calculation if one reservoir is available; otherwise, setting scattering-state step length and scattering number and selecting a proper orthogonal table according to the number of the reservoirs and number of scattering states; determining initial reservoir scheduling trajectories involved in optimal calculation; resolving the original reservoir optimal scheduling problem into multiple subproblems by the successive approximation algorithm; calculating each state combination and performing statistic analysis by a penalty function method according to reservoir condition combination evenly distributed in a constraint space of an orthogonal table structure, and rapidly acquiring the optimal state combination of the subproblems; performing the optimal calculation on the subproblems in sequence, and successively approximating an optimal solution of the original problem. By the application of the reservoir scheduling method, calculation dimensions of the reservoir optimal scheduling problems can be lowered, calculation efficiency can be improved, and the reservoir scheduling method is applicable to a single-reservoir optimal scheduling and group-reservoir optimal scheduling as well as water resource optimal allocation.

Description

technical field [0001] The invention relates to a reservoir (group) scheduling method based on an orthogonal successive approximation algorithm, and belongs to the technical field of water resources and reservoir (group) optimization scheduling. technical background [0002] Reservoir (group) optimal dispatching seeks reasonable and feasible dispatching plans and programs to guide the operation of reservoirs (groups) under the principle of dispatching, which can increase economic benefits by 1% to 7% compared with conventional dispatching. Therefore, it is very necessary to carry out joint optimization of reservoirs and groups Research on scheduling problems. The long-term operation of reservoirs (groups) generally adopts the maximum power generation model, which is mathematically described as the process of the beginning and end water levels and inflow flow of each reservoir within the known operation period, comprehensively considering various constraints such as water lev...
