Study on dimension reduction for optimal operation of large-scale hydropower system Ⅱ.Example for the method
摘要
Abstract
In order to solve the curse of dimensionality of joint optimal operation of large-scale hydropower system,orthogonal dimension reduction search algorithm (ODRSA) is presented on the basis of orthogonal experiment design.ODRSA solves the joint optimization scheduling problem of hydropower system by carrying out the orthogonal experimental design in the neighborhood of initial solution.During the iteration,some representative solutions are selected to calculate and the starting point will be replaced if the better solution is found.Analysis shows that the time complexity and space complexity of ODRSA are square.Simulation results of the cascade hydropower stations on the Wujiang River indicate that:ODRSA is a novel method for large-scale hydropower system with less calculation parameters,fast convergence speed and strong robustness.关键词
