Analysis On Optimized Reservoir Scheduling Coupling Model

The researchers usually take the output power factor as a constant in the mid or long-term optimal reservoir scheduling calculation, but it is a dynamic factor that changes with working condition and has much influencing factor. Operators who have experience should confirm it on the basis of working condition subjectively. In addition, operators don't take into account of operational aspect of sets when they ensure the decision variable Q of reservoir operation. For example, sets locate in shake area for the decision variable Q. This paper proposes optimized reservoir scheduling coupling model on the basis of run off prediction and economic operation situation of plant in order to obtain higher precision. The model takes the decision variable Q as coupling variable and reservoir operation and in-plant economic operation are connected by it. At last, operators can get multiple output factors according to operational condition of sets.This paper mainly contains below work in allusion to the above problem:(1) It proposes optimized reservoir scheduling coupling model, in addition, reservoir operation and in-plant economic operation are connected according to coupling variable Q. Multiple output factors are confirmed on the basis of real operational aspect.(2) In order to obtain higher precision, this paper adopts dynamic programming method to solve the model and works out C++ calculation program.(3) This paper takes the YanShan reservoir as example. It applies the model into the example and compares the YanShan reservoir with reservoir operation model which has constant multiple output factors. Calculated results manifest the model is reasonable and have higher precision.At last, this paper proposes some shortcomings and further study's direction for time limit and concludes the above.
