Research On Optimal Operation Function Of Reservoir

The optimal operation of reservoir/multireservoir is to develop rules for managing reservoir/multireservoir for more benefits. There are a variety of methods, such as stochastic optimal method and implicit stochastic optimal method. The main difficulty of stochastic optimal method is how to establish the transfer probability matrix and escape the"curse of dimensionality"in the course of solving. Two steps included in implicit stochastic optimal method: (1) Using the deterministic optimization of reservoir operation algorithm and finding out a optimal operation mode with the historical information of runoff. (2) Based on the results of the first step, choose the decision-making relate to the operation and establish the regression equations as a function of scheduling rules through regression analysis of the regression equation, which guides the operation of reservoir/multireservoir.This paper introduces the optimal reservoir management background, history, general principles and methods and expatiates on the Progressive Optimization Algorithm and Support Vector Machine (SVM), which was showed on how to use it and proved more available compared with other methods. There are some thoughts and suggestions at the last.This paper will focus on:(1) In order to solve the"curse of dimensionality",the Progressive Optimization Algorithm and Variable Step-Size Two-way Search Algorithm are used. They are convergent and get global optimal solution fleetly.(2) According to the complexity and non-linearity of the reservoir operation function and the finiteness of the hydrographic information,an optimization reservoir operation function is established using SVM technology. Compared with different methods and instances, it has been confirmed having better performance than others.(3) Based on two points above, we also discuss the essential difficulty of the optimal operation of reservoir by the Information Theory and give some annotations and suggestions. But the complexity and uncertainty of this difficulty induce a long, difficult and hazardous further exploration, which we will work hard on.
