A method and system for fine-tuning control of all ecological elements of a cascade reservoir group

Abstract

The present invention proposes a fine scheduling control method and system for all ecological elements of a cascade reservoir group. The present invention randomly initializes the population under the constraint of the water level of the reservoir to obtain an initial population containing multiple individuals; calculates the individual fitness value in the current population, and updates it The global optimal position of the population and the optimal position of the individual history; the introduction of the individual historical optimal position and the random individual position in the elite individual set increases the diversity of the population, effectively avoiding individual "premature convergence"; the introduction of a refined search strategy effectively improves the population Convergence accuracy; update the positions of all individuals in the population through iterative calculation until the maximum number of iterations of the population is reached; output the global optimal position of the current population as the final scheduling process of the cascade hydropower station. Compared with the classical intelligent optimization method, the present invention has high robustness, can effectively reduce the ecological water shortage of the entire cascade reservoir, thereby achieving the purpose of protecting the watershed ecology; meanwhile, the present invention has a simple principle and high solution accuracy.

Description

technical field [0001] The invention belongs to the field of ecological regulation of cascade reservoir groups, and more particularly relates to a control method and system for fine regulation of all ecological elements of cascade reservoir groups. Background technique [0002] The operation results of many large-scale cascade hydropower stations in operation show that the construction and operation of hydropower stations not only bring huge social and economic benefits, but also change the hydrological regime of natural runoff, which poses a serious threat to the health of the basin ecosystem. [0003] The main purpose of reservoir construction is to regulate the flow of water and play the role of flood retention and water storage, but at the same time it will bring adverse effects such as sediment deposition in the reservoir, rising water temperature, poor water quality and serious erosion of the downstream riverbed. In order to improve the negative impact of reservoir con...
