Optimal Operation Study of Qing River Cascade Reservoirs Based on GA with Uncertainty and Flow Transmission Considered

摘要

This paper presented a simulation method which considers the uncertainty and flow transmission in optimal operation of Qing River cascade reservoirs. Latin hypercube method was applied to simulate the uncertain inflow, and its sampling frequency and accuracy were very satisfied. Linear regression method was used to deal with the damping and deformation in the process of flow transmission. And Genetic algorithm(GA) was found application for solving the optimal operation model of Qing River cascade reservoirs. According to the method presented we could obtain the scheduling scheme of cascade reservoirs under different risk rates which were helpful to the decision-making. The result showed that the method is practical.
