Abstract

The invention provides a reservoir optimization scheduling decision-making method and device for aquatic community system stability, and the method comprises the steps: 1, determining a research scene, collecting basic data and historical scheduling data of a reservoir group system, and hydrological data and biomass data of a downstream station, and determining an impact factor and a decision variable of a reservoir scheduling behavior; 2, considering interaction among multiple populations, and constructing a random multi-population dynamic model; 3, calculating hydrological variation degree, describing disturbance of hydrological variation on the aquatic community through noise intensity, establishing a'flow-ecology 'relationship, and analyzing the stability of the aquatic community system under the influence of the hydrological variation; 4, identifying the resilience and the resistance of the multi-population system by adopting two ecological indexes, namely steady-state time ST and a variable coefficient CVST at the steady-state time; and 5, comprehensively considering reservoir water supply and power generation targets and ST and CVST ecological targets, optimizing a reservoir operation curve, and obtaining a reservoir optimization scheduling decision.

Description

technical field [0001] The invention belongs to the technical field of reservoir dispatching, and in particular relates to a decision-making method and device for optimal dispatching of reservoirs oriented to the stability of aquatic community systems. [0002] technical background [0003] Reservoirs are widely used flood storage and dry-water projects. According to the "2018 National Water Conservancy Development Statistical Bulletin", a total of 98,822 reservoirs have been built in my country. With the global socio-economic development at the expense of ecological and environmental benefits, the sustainable development of wetland ecosystems has received more and more attention. How to enhance the stability and sustainability of aquatic ecosystems through optimal reservoir scheduling decisions has become a research hotspot, which has prompted relevant scholars to focus on hydrological processes as well as physical and ecological processes that are beneficial to aquatic comm...
