摘要
介绍了模拟退火算法的基本原理,在原算法的基础上,针对实际应用中最后当前解是近似最优解且有可能比中间解差的情况,提出了将搜索过程与最优解更新序列分离的改进措施,通过设定阈值分别判断抽样过程和退火过程是否结束以保证解的最优性。最后,通过IEEE—30节点和IEEE—118节点系统无功优化算例说明改进算法具有建模简单,对系统的规模量不敏感,计算内存小及具有较好鲁棒性等优点。
This paper introduces a simulated annealing algorithm and presets an improved simulated annealing algorithm with a decomposition of searh procedure and iteraive order of optimization, which ensure an optimal soution by defining a limitation in order to judge a sample procedure and annealing procedure. Finally, the experimental results are given to prov it's effccency.
