Optimization method for joint flood dispatching of cascade reservoirs coupled with flood control and power generation

Abstract

The invention discloses a cascade reservoir combined flood scheduling optimization method coupled with flood control and power generation, which can coordinate flood control and power generation goals in flood scheduling, and adopt corresponding models for different standard floods, timely power generation pre-discharging and closing gates and staggered peaks, reducing flood seasons It is useless to abandon water to maximize the benefits of cascade reservoir flood control and power generation. The technical solution is: judge the level of the flood according to the real-time hydrometeorological information and flood forecast results. When the average inflow flow during the flood period is greater than the full flow of the power station, it will be judged as a major flood, otherwise it will be judged as a small flood; according to the different levels Different models are used to optimize the scheduling of different control objectives; under each different flow, constraint settings and control objectives, a number of different flood control schemes are obtained, which constitute a set of flood control schemes corresponding to a flood, as the basis for decision-making, if In the flood control scheme set, it is necessary to modify the inflow flow, so the simulated flood control calculation under various inflow conditions is repeated.

Description

technical field [0001] The invention relates to a flood dispatch optimization method, in particular to a cascade reservoir combined flood dispatch optimization method coupled with flood control and power generation. Background technique [0002] The combined flood regulation of cascade reservoirs has attracted more and more attention. At present, most of the optimization methods for cascade reservoir joint flood dispatching take large floods as the research object, mainly for the benefit of flood control. The scheduling of reservoirs during flood periods essentially involves two aspects of flood control and power generation. Flood characteristics, project storage and discharge control capabilities, and actual flood control requirements should be considered comprehensively, and the contradictions between flood control and power generation, economic benefits, and flood control safety should be scientifically handled. At present, there is a lack of models and methods in the jo...
