Coupling optimization model of hydropower station power dispatching based on complex dispatching constraints and cascade joint commissioning

Abstract

In order to increase the average power generation of a hydropower station and reduce its water consumption, this paper proposes a hydropower dispatching coupling optimization model based on complex dispatch constraints and cascade-connected dispatching. The power generation water consumption and the remaining load of the power grid are used as the objective function to construct a power dispatch coupling optimization model. After all the constraints are met to solve the objective function, the improved genetic algorithm and the coupling constraint adjustment strategy are combined to form a hybrid search method to realize the genetic operation. The strategy is improved to complete the optimization of power dispatch. The experimental results show that the above model can effectively realize the optimization of power dispatch and increase the average power generation of hydropower stations. It is hoped that the model can reasonably optimize the power dispatch during the flood season and the dry season, thereby effectively reducing the water consumption of the cascade and increasing the power generation of the cascade.
