Reservoir optimal scheduling decision-making method and device for aquatic community system stability

Abstract

The invention provides a decision-making method and device for reservoir optimization and dispatching oriented to the stability of an aquatic community system. The method includes: step 1. Determine a research scenario, collect basic data of the reservoir group system, historical dispatch data, hydrological data and biomass data of downstream stations, and determine the reservoir. Influencing factors and decision variables of dispatching behavior; Step 2. Consider the interaction between multiple populations, and build a random multi-population dynamic model; Step 3. Calculate the hydrological variability, and describe the disturbance of the hydrological variability to the aquatic community through the noise intensity. ‑Ecology” relationship, to analyze the stability of the aquatic community system under the influence of hydrological variability; Step 4. Use two ecological indicators, the steady-state time ST and the coefficient of variation CVST at the steady-state time, to identify the resilience and resistance of the multi-population system, respectively. Step 5. Comprehensively consider the reservoir water supply, power generation goals, and ST, CVST ecological goals, optimize the reservoir operation curve, and obtain the reservoir optimization scheduling decision.

Description

technical field [0001] The invention belongs to the technical field of reservoir scheduling, and in particular relates to a decision-making method and device for optimal scheduling of a reservoir oriented to the stability of an aquatic community system. [0002] technical background [0003] Reservoirs are widely used flood storage and dry-up projects. According to the 2018 Statistical Bulletin of National Water Conservancy Development, a total of 98,822 reservoirs have been built in my country. With the global social and 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 decision-making for optimal scheduling of reservoirs has become a hot research issue, which prompts relevant scholars to focus on hydrological processes, as well as physical and ecological processes that benefit aquati...
