Optimal Control of Large Flood of Ankang Reservoir

Abstract

Located in the upper stream of the Hanjiang River, the Ankang Reservoir is a large hydro-junction mainly for electric power generation as well as for flood prevention and shipping. Rainstorms in the Hanjiang River in summer have high occurrence with concentrated floods characterized by sudden surge and sudden fall. Considering staggering the Hanjiang River and the Yuehe River flood peaks, on the premise of ensuring the dam safety and meeting the flood prevention requirements of Ankang Town, this Thesis establishes the mathematical model for the Ankang Reservoir large flood multi-objective optimal deployment, adopts the progressive optimality algorithm (POA) to solve the model to work out the optimal control with the inconsistent objectives of flood prevention and power generation during large flood and gives examples. The result shows that the mathematical model is workable and practicable and the solution methods are rapid and accurate.
