Cascade power generation and ecological balance optimization scheduling method and device, equipment and medium

Abstract

The invention provides a cascade power generation and ecological balance optimization scheduling method and device, equipment and a medium. The method comprises the following steps: obtaining the annual runoff change of a river of the cascade hydropower station, calculating the ecological flow of the cascade hydropower station by adopting a ten-day-by-ten-day frequency method, and determining theupper and lower limits of the ecological suitable flow and the minimum and maximum ecological flows of the cascade hydropower station; setting an objective function and constraint conditions to establish a power generation and ecological balance optimization scheduling model; and optimizing a scheduling result according to the power generation and ecological balance optimization scheduling model based on an improved whale algorithm. The method can achieve organic unification of economic benefits and ecological benefits of the cascade power station, find out the optimal balance point of the power generation benefits and the ecological benefits, and effectively improve the ecological flow environment of the riverway under the stress of water conservancy projects. By changing the hydropower station scheduling mode, the water requirement of the river ecosystem is met to the maximum extent, the natural runoff mode of the river channel is well maintained, and the influence of human power generation requirements on river ecology is reduced.

Description

technical field [0001] The present application relates to the technical field of computer data processing, in particular to a cascaded power generation and ecological balance optimization scheduling method, device, equipment and medium. Background technique [0002] The cascade hydropower station group refers to a hydraulic engineering system composed of multiple hydropower stations with upstream and downstream relationships and hydraulic connections located in the same river basin. If the hydropower stations in the basin operate independently, it is very likely to cause local imbalances such as too much water discarded by some hydropower stations or insufficient water flow from downstream power stations. On the premise of weighing the comprehensive needs of each hydropower station, it is particularly important to maximize the complementary benefits between hydropower stations. A reasonable cascade power station joint optimization dispatch strategy must not only meet the or...
