Abstract

The invention provides a cascade hydropower dispatching model optimization method and device, electronic equipment and a storage medium. The method comprises the following steps: constructing a first constraint condition of a cascade hydropower dispatching model: generating a hydroelectric power generation function tetrahedral convex envelope. According to the scheme, an original non-convex nonlinear cascade hydropower dispatching model is converted into a linear programming model, the problem that a non-convex model is prone to falling into local optimum is avoided, the problem solving speed is remarkably increased, and efficient making of a dispatching plan is facilitated.

Description

technical field [0001] The invention belongs to the technical field of optimization scheduling, and in particular relates to a cascade hydropower scheduling model optimization method, device, electronic equipment and storage medium. Background technique [0002] With the development and utilization of hydropower resources, the cascade development of hydropower continues to develop, and the thirteen major hydropower bases planned in my country have gradually formed a situation of joint dispatch of cascade hydropower groups. In order to improve the level of scientific development and rational utilization of hydropower resources, and to enhance the comprehensive benefits of hydropower, the cascade hydropower optimal dispatching theory based on operations research was proposed and developed continuously. However, the cascade hydropower group has complex hydraulic and electric power connections, water supply, flood control, forecasting, market and many other factors that need to ...
