The Reservoir's Optimal Operation Modeling Based on Mixed DE-PSO Algorithm

WANG Fang;YANG Hushan;Department of Mathematics,Xinzhou Teachers College;  
The calculation of reservoir's optimal operation is discussed in the paper as a problem of a nonlinear inequation's constraint and optimization.After some comparison and analysis,it is found out that accuracy and constraint disposal have always been given scant attention in the extant calculating methods,and that the related research is sparse as well.In order to overcome these defects,the particle swarm optimization and differential evolution algorithms are proposed to build an optimal DE-PSO model for reservoir's operation avoiding the bottleneck in the optimizing process.To solve the problems of complex constraints existing in the the particle swarm and differential evolution algorithms,this paper puts forward an annealing penalty function to effectively overcome the above shortcomings in reservoir optimal operation.Through the computation and analysis,the availability and feasibility of the DE-PSO algorithm are verified by its application to reservoir's optimal operation.
