Embodiment Construction
[0088] In order to make the purpose, technical solution and points of the present invention clearer, the technical solution of the present invention will be introduced below in conjunction with the embodiments of the present invention.
[0089] A cooperative value assessment method for reservoir dispatching and ecological environment protection of downstream rivers, comprising the following steps:
[0090] Step 1: Identification of ecological base flow by Eckhardt double-parameter filtering method
[0091] First, divide the annual flow process of the hydrological control station into m segments according to a given time interval N, and determine the minimum flow sequence of each segment (q 1 ,q 2 ,...,q m ); and then determine the inflection point from it (if satisfying k×q t less than q t-1 and q t+1 , then q t is the inflection point); then connect all the inflection points to obtain the base flow process, and the base flow between the inflection points is obtained by ...

The invention discloses a cooperative value evaluation method for reservoir dispatching and ecological environment protection of downstream rivers. Before carrying out reservoir ecological dispatching, the initial method is improved by using Eckhardt filter technology to generate a daily scale ecological base flow; Taking ecological indicators as different goals, a multi-objective optimization model that comprehensively considers power generation, ecology, and shipping processes is established; at the same time, considering the cooperation model between hydropower generation goals and ecological goals, a cooperative scheduling scenario of two main alliances is established; and The ecological value of the complex reservoir system for cooperative ecological regulation on the downstream channel is evaluated by the optimal calculation results between different scenarios and the cooperative ecological value under different weight conditions. The present invention establishes a cooperative value evaluation model by evaluating the ecological value of the complex reservoir system for cooperative ecological regulation on downstream rivers, and provides multi-dimensional theoretical basis for reservoir regulation.
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. E...
