Abstract

The embodiment comprises a method and a device for realizing optimization scheduling of a watershed cascade hydropower station and aims to carry out optimization scheduling of a watershed cascade hydropower system. The system comprises at least one hydropower station, the device comprises a computing module, a constraint module, a constraint space generation module and an optimization module. Optimization scheduling model processing is a point of penetration, a water level constraint space contraction method is utilized to contract the water level traversal space, the cascade hydropower system is partitioned on the basis of a large-scale system decomposition coordination idea, coordination optimization is carried out, on the condition that an algorithm optimization mechanism is not changed, an optimization problem is considered, searching optimization efficiency is improved, and relatively good practicality is realized.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method and device for optimal scheduling of cascade hydropower stations in a river basin. Background technique [0002] With the completion and commissioning of large-scale river basin cascade hydropower stations in Southwest my country, their operating status has increasingly significant impact on the safety, stability and operational efficiency of the power system. Therefore, it has become a research hotspot to study the optimal dispatching strategy of river basin cascade hydropower stations to ensure the stable and efficient operation of hydropower stations and power grid systems. . [0003] The coupling relationship between hydraulic power and electric power between cascade hydropower stations in the basin makes the optimal dispatching model present the characteristics of high dimensionality, multi-constraints, nonlinearity, and multi-period. For discrete variables, the calcula...
