Optimization of Parallel Reservoirs for Flood Control Based on the Aggregation-Decomposition Method
Abstract: The optimal operating rules for parallel reservoirs were built based on the aggregation-decom- position method. The relationship between the total release of the reservoirs and the aggregation reservoir storage could be expressed by piecewise-linear operating rules in the aggregation step, and the release was decomposed to each parallel reservoir according to its ratio of inflow in the decomposing procedure. Then the optimization model of parallel reservoirs was built, and its key parameters were calibrated by the Genetic Algorithm. Three parallel reservoirs (the Baise, Longtan and Qingshitan reservoirs) of the Xijiang River in China were selected for a case study. The optimal flood operating rules were compared with the conventional operating rules, and the flood peak of reference station for flood control could be decreased by 970 m3/s and 1320 m3/s in calibrated and validation periods, respectively. Thus, this method is beneficial for the reservoir’s real- time operation to decrease the flood disasters.
