Study On The United Optimal Dispatching Of Cascaded Hydropower Plant In Lower Reaches Of Dadu River Basin

With the Pubugou, Shenxigou, and so on the development and construction of power stations have been put into operation, the lower reaches of the Dadu River valley in the near future will be formed to Pubugou, Shenxigou, Gongzui, Tongjiezi station of the four major sub-components of the cascade hydropower stations group, the Large-scale capacity, the number of power stations, good conditioning, water and electricity in the domestic industry in the forefront. Pubugou dam in order to represent the lower reaches of the River cascade hydropower stations of the four major joint operation of power generation optimization for improving the Dadu River in Sichuan basin of water and electricity as well as the overall generation capacity, to improve the quality of electricity supply to ease power grid in Sichuan between water peak period and dry season, between peak and valley, optimization Sichuan power structure, will play an increasingly important role. In this paper, the Dadu River valley downstream of the actual situation, mainly on the lower reaches of the Dadu River valley in order to control for the Pubugou dam's hydroelectric power generation in four steps optimization problems more systematically studied, the research include:First of all, the analysis of the selection of background papers, as well as hydroelectric power generation at home and abroad for the optimal operation of the aspects of research on this thesis research purposes, and to establish a research and papers to be the main problem-solving, as specified in the direction of the research paper.Secondly, the use of dynamic programming approach to the cascade power stations in the largest power generation and water years, the minimum time and effort as far as possible, a significant goal of the Dadu River valley had a cascade power generation and long-term optimal operation, using examples of calculation and analysis of the results of the optimization.Then, successive use of optimization and genetic algorithms to generate electricity on income and the largest daily load between the plant targets for the rational allocation of the Dadu River valley cascade power generation short-term optimization studies, using examples of calculation and analysis of the results of the optimization.Finally, based on the establishment of the Cascade River Power generation optimization model for the Dadu River valley cascade power generation planning system design and simulation to guide the actual production scheduling.
