Abstract

The invention relates to a reservoir scheduling method based on spiral local search. The method comprises the following steps: step 1, establishing a reservoir optimization scheduling generating capacity maximum model; 2, a spiral local search algorithm and a bat algorithm are combined, so that the objective function of the mathematical model established in the step 1 is maximum, namely the reservoir generating capacity is maximum. The method has the beneficial effects that a spiral local search algorithm and a bat calculation method are combined to solve the problem of complicated constraintof reservoir scheduling, the reservoir scheduling level is effectively improved, and a new method is provided for solving the problem of complicated constraint of reservoir scheduling.

Description

technical field [0001] The invention relates to a reservoir optimization scheduling algorithm in the field of water resources, in particular to a reservoir scheduling method based on spiral local search. Background technique [0002] Reservoir optimal dispatch is an important means of optimal utilization of water resources. Reservoirs usually take into account functions such as power generation, flood control, irrigation, and water supply. In the power generation dispatching of reservoirs, the reservoir optimal dispatching problem is a high-dimensional, multi-constraint, nonlinear complex optimization problem. Research on this problem has always been a hot topic among scholars. Traditional dynamic programming algorithms are prone to the curse of dimensionality. Therefore, evolutionary algorithms are often used in research this year to solve optimal reservoir scheduling problems. However, most of the evolutionary algorithms have premature problems, and the final result is no...
