Problems solved by technology

The disadvantage of this method is that it only optimizes the scheduling process of reservoir groups for ecological, power generation, and water supply goals, and does not fully consider the regional economic and social development and the preference information of decision makers. It has a shortpart

Abstract

The invention provides a method for coordinated allocation of water resources for ecological power generation and water supply, which includes acquiring data and information, and further comprising the following steps: calculating the water demand of each calculation unit and the suitable ecological flow of each ecological section, and fitting the relationship between the power generation capacity of the reservoir and the power generation water capacity. build a water allocation model for ecology, power generation and water supply, and optimize the solution to obtain the optimal solution set; make decisions on the results of the model solution, and obtain a monthly water allocation plan; The process of daily inflow and runoff of the reservoir in the next month; the short-term regulation model of the reservoir is constructed, and the daily-scale reservoir flow regulation scheme is obtained by optimizing the solution; the daily-scale flow regulation data is integrated into the monthly-scale water volume data, and the input data of the configuration model is modified. The present invention comprehensively considers the synergistic and competitive relationship among river basin ecology, power generation and water supply goals, and provides support for river basin water resources management and comprehensive and efficient utilization of water resources.

Description

technical field [0001] The invention relates to the technical field of water resource allocation, in particular to a water resource coordinated allocation method for ecological power generation and water supply. Background technique [0002] Water resources allocation is an important means to optimize water resources management and improve the efficiency of water resources development and utilization. It consists of two aspects: water resources allocation and reservoir scheduling. The allocation of water resources focuses on the distribution of water resources in the basin to alleviate the contradiction between water supply and demand caused by economic and social development, and has guiding significance for the development, utilization and management of water resources. Reservoir scheduling focuses on regulating the flow process of nodes or sections, including flood control scheduling, ecological scheduling, power generation scheduling, etc. It is the main basis for reserv...
