Genetic algorithms often cause premature convergence and can not give out global optimality in solving UC problems,while the simulated annealing algorithm shows better performance in accepting new solutions.By introducing annealing algorithm to the evaluation functions and the selection manipulation,the selection manipulation and the global convergency can be improved.Using decimal coding with no decoding,both the calculation error and time for calculation can be reduced.The example shows that this hybrid algorithm can improve the economic performance of UC scheme while various restrictions for security and reliability are still satisfied. |
