Dynamic planning improvement algorithm for power generation dispatching of cascade reservoir group

Abstract

The invention discloses a dynamic planning improvement algorithm for power generation dispatching of a cascade reservoir group, and relates to the fields of reservoir operation dispatching and water conservancy information. The method comprises the steps of performing postorder traversal on the cascade reservoir group to obtain an optimized sequence; running a dynamic planning algorithm by an initial solution according to any reservoir A in the optimized sequence to obtain an initial solution sequence of reservoir dispatching of the reservoir A, wherein the initial solution is reservoir capacity or a water level discrete quantity; based on the initial solution sequence, further optimizing the initial solution sequence by using continuous linear planning to obtain an optimized initial solution sequence; and taking the reservoir capacity or a water level value in the optimized initial solution sequence as power discharge of a dispatching decision, and updating outflow runoff of the reservoir A according to the power discharge of the dispatching decision, thereby finishing a reservoir dispatching decision, synthesized based on a reservoir dispatching rule, of the reservoir A. The algorithm is suitable for medium-long-term dispatching of the cascade reservoir group; an actual optimal solution can be obtained; and the solving time is shorter.
