Cooperative value evaluation method for reservoir scheduling and downstream river ecological environment protection

Abstract

The invention discloses a cooperative value evaluation method for reservoir scheduling and downstream river ecological environment protection, and the method comprises the steps of carrying out the improvement of an initial method through employing an Eckhardt filtering technology before reservoir ecological scheduling, and generating a daily-scale ecological base flow; taking power generation benefits and ecological indexes of the hydropower station as different targets, and building a multi-target optimization model comprehensively considering power generation, ecology and shipping processes; meanwhile, considering a cooperation mode between a hydropower station power generation target and an ecological target, and setting a cooperation scheduling scene of two subject alliances; and evaluating the ecological value of the complex reservoir system for cooperative ecological scheduling on the downstream riverway through the optimal calculation result among different scenes and the cooperative ecological value under different weight conditions. The cooperative value evaluation model is established by evaluating the ecological value of cooperative ecological scheduling carried out bythe complex reservoir system on the downstream river channel, and a multi-dimensional theoretical basis is provided for reservoir scheduling.

Description

technical field [0001] The invention belongs to the field of optimal dispatching of reservoirs, and relates to a set of ecological cooperation value evaluation system, in particular to a cooperation value evaluation method for reservoir dispatching and ecological environment protection of downstream rivers. Background technique [0002] The reservoir system is changeable, and it is a complex system with multiple objectives and multiple subjects. It also has the functions of flood control, power generation, ecology, shipping and water supply. There are conflicting and mutually supportive relationships among these goals. Now, the ecological value of rivers and lakes system is being emphasized more and more, but a common evaluation standard in the industry has not yet been produced. On the basis that the ecological value of rivers has not yet been fully evaluated, reservoirs across the country have vigorously promoted ecological regulation programs with different standards.

Problems solved by technology

Ecological dispatch means that during the dispatching process, the reservoir deliberately maintains a certain amount of discharge to maintain the ecological environment inside and outside the river. This dispatching method will affect the power generation efficiency of hydropower stations
